Answer: 32, 25, and 13 are possible side lengths.
Step-by-step explanation:
The lengths of any two sides of a triangle must sum up to more than the length of the third side.
15 + 27 = 42
42 = 42
The sum has to be MORE than the third side.
15 + 27 = 42
42 > 11
15 + 11 = 26
26 < 27
The sum of two sides can't be LESS than the third side.
15 + 27 = 42
42 > 32
15 + 32 = 47
47 > 27
27 + 32 = 59
59 > 15
Possible Side Length!
15 + 27 = 42
42 < 45
Can't be less
15 + 27 = 42
42 > 25
15 + 25 = 40
40 > 27
27 + 25 = 52
52 > 15
Possible Side Length!
15 + 27 = 42
42 > 13
15 + 13 = 28
28 > 27
27 + 13 = 40
40 > 15
Possible Side Length!

Levin Furniture buys a living room set with a $4,900 list price and a 50% trade discount. Freight (FOB shipping point) of $45 is not part of the list price. What is the delivered price (including freight) of the living room set, assuming a cash discount of 4/10, n/30, ROG? The invoice had an April 8 date. Levin received the goods on April 19 and paid the invoice on April 25.
Delivered price = $Answer:
Answer:Delivered price=$1,814
Step-by-step explanation
Explanation:
List Price = $4,000
Trade discount = 55%
Price after discount = $4,000 - 55% x $4000
$4000- $2,200 = $1,800
if Levin pays within 10 days he will have a discount of 2 %, which he did
Therefore 2% x $1800 = $36
Delivered price = $1800 -$36+ freight charges ( shipping)
$1800 -$36 + $50=$1814
The speed of the current in a creek is 5 mph. A person clan kayak 3 mi upstream in the same time that it takes him to kayak 13 mi downstream. What is the speed
the person's kayak in still water?
The speed of the person's kayak in still water is
Answer:
8
Step-by-step explanation:
0) the basic formula is: L=v*t, where L - distance, v - speed/velocity; t - time;
1) if the person's speed in still water is 'v' and the speed of water is 5 (according to the condition), then the upstream speed is 'v-5' and the downstream speed is 'v+5';
2) according to the condition the upstream time and the downstream time are the same, it means t₁=t₂=t, where t₁=upstream time and t₂=downstream time;
3) according to the items above it is possible to make up the equation of the upstream travel: t(v-5)=3; ⇒ t=3/(v-5);
4) according to the items above it is possible to make up the equation of the downstream travel: t(v+5)=13; ⇒ t=13/(v+5);
5) if t=3/(v-5) and t=13/(v+5), then
[tex]\frac{3}{v-5} =\frac{13}{v+5}; \ => \ v=8.[/tex]
Please help me with an explanation so i can understand it better
Answer:
9.5
Step-by-step explanation:divide area by 12.3
i think it is right
Answer:
u= 19 miles
Step-by-step explanation:
Area of triangle= ½ ×base ×height
Given that the area is 116.85 mi² and height= 12.3 mi,
116.85= ½ ×u ×12.3
6.15u= 116.85
u= 116.85 ÷6.15 (÷6.15 on both sides)
u= 19 mi
Russell wants to buy three ties and a belt and must spend no more than $80.00. The belt costs $28.50. If the three ties are the same price, then how much can he pay for each tie
Answer:$17.16
Step-by-step explanation:
do you have to start by subtracting the cost of the belt from the total budget: 80-28.5= 51.5. Then you can divide the remaining money by three because he’s buying three ties: 51.5/3≈ $17.16
What is the multiplicative inverse of y?
Answer:
The multiplicative inverse of y is [tex]\frac{1}{y}[/tex].
Step-by-step explanation:
Multiplicative inverse implies a value that you would multiply with the given value so as to give 1.
Let the multiplicative inverse of y be represented by a, so that;
a x y = 1
ay = 1
divide both sides by y to have,
a = [tex]\frac{1}{y}[/tex]
Thus, the multiplicative inverse of y is [tex]\frac{1}{y}[/tex].
This is applicable to any given value. Examples:
i. Given 2, the multiplicative inverse is [tex]\frac{1}{2}[/tex].
⇒ 2 x [tex]\frac{1}{2}[/tex] = 1
ii. What is the multiplicative inverse of 5?
The required answer is [tex]\frac{1}{5}[/tex].

You find that you receive on average about 3 pieces of junk mail per week. Find the probability that the number of pieces of junk mail you receive next week will be (a) none at all. (b) exactly four. (c) no more than two. (d) more than two g
Answer:
a) 0.0498 = 4.98% probability that the number of pieces of junk mail you receive next week will be none at all.
b) 0.1680 = 16.80% probability that the number of pieces of junk mail you receive next week will be exactly four.
c) 0.4232 = 42.32% probability that the number of pieces of junk mail you receive next week will be no more than two.
d) 0.5768 = 57.68% probability that the number of pieces of junk mail you receive next week will be more than two.
Step-by-step explanation:
We have only the mean, which means that we use the Poisson distribution to solve this question.
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:
[tex]P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}[/tex]
In which
x is the number of sucesses
e = 2.71828 is the Euler number
[tex]\mu[/tex] is the mean in the given interval.
You find that you receive on average about 3 pieces of junk mail per week.
This means that [tex]\mu = 3[/tex]
(a) none at all.
This is P(X = 0).
[tex]P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}[/tex]
[tex]P(X = 0) = \frac{e^{-3}*3^{0}}{(0)!} = 0.0498[/tex]
0.0498 = 4.98% probability that the number of pieces of junk mail you receive next week will be none at all.
(b) exactly four.
This is P(X = 4).
[tex]P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}[/tex]
[tex]P(X = 4) = \frac{e^{-3}*3^{4}}{(4)!} = 0.1680[/tex]
0.1680 = 16.80% probability that the number of pieces of junk mail you receive next week will be exactly four.
(c) no more than two.
This is:
[tex]P(X \leq 2) = P(X = 0) + P(X = 1) + P(X = 2)[/tex]
[tex]P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}[/tex]
[tex]P(X = 0) = \frac{e^{-3}*3^{0}}{(0)!} = 0.0498[/tex]
[tex]P(X = 1) = \frac{e^{-3}*3^{1}}{(1)!} = 0.1494[/tex]
[tex]P(X = 2) = \frac{e^{-3}*3^{2}}{(2)!} = 0.224[/tex]
[tex]P(X \leq 2) = P(X = 0) + P(X = 1) + P(X = 2) = 0.0498 + 0.1494 + 0.224 = 0.4232[/tex]
0.4232 = 42.32% probability that the number of pieces of junk mail you receive next week will be no more than two.
(d) more than two
[tex]P(X > 2) = 1 - P(X \leq 2) = 1 - 0.4232 = 0.5768[/tex]
0.5768 = 57.68% probability that the number of pieces of junk mail you receive next week will be more than two.
Luis is shopping for gifts. Mugs are on sale for $4 off the regular price,p. Luis vuys 6 muga. H epays $54. What is the regular price of the mug? Show your work.
Answer:
13
Step-by-step explanation:
Divide the total amount he paid by the amount of mugs he bought to find out how much each mug cost.
54 ÷ 6 = $9
Each mug is nine dollars, INCLUDING THE SALE which is $4 off.
Add $4 to $9 to find the regular price
$4 + $9 = 13
The regular price of the mugs based on the given equation will be $13.
What is the equation?There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.
More than one variable may be present inside a linear equation.
Suppose the regular price is x.
Selling price = $4 off of x = x - 4
Number of mugs buys = 6
Paid = $54
54= 6 (x - 4)
(x - 4) = 9
x = 13
Hence "The regular price of the mugs based on the given equation will be $13".

How many times does the line y=-6 intersect with the circle x^2+y^2=36?
Answer:
a) The line intersects with the circle once.
b) Tangent
Step-by-step explanation:
We are given the following equation for the circle:
[tex]x^2 + y^2 = 36[/tex]
How many times does the line y=-6 intersect with the circle?
We have to find the values of x when [tex]y = -6[/tex]
So
[tex]x^2 + y^2 = 36[/tex]
[tex]x^2 + (-6)^2 = 36[/tex]
[tex]x^2 + 36 = 36[/tex]
[tex]x^2 = 0[/tex]
[tex]x = 0[/tex]
Since the line intersects the circle at one point, it is tangent to the circle.
The line intersects with the circle once.

How do scientists identify tectonically active regions
Answer: plate tectonics
Step-by-step explanation:Most earthquakes and volcanic eruptions do not strike randomly but occur in specific areas, such as along plate boundaries. One such area is the circum-Pacific Ring of Fire, where the Pacific Plate meets many surrounding plates. The Ring of Fire is the most seismically and volcanically active zone in the world.

A fruit stand sells bags of apples and tangerines. • Each bag has 3 fewer apples than tangerines. 2 • In each bag, the number of apples is the number of tangerines. Let A represent the number of apples in each bag and T represent the number of tangerines in each bag. Which system of equations can be used to solve for A and T?
Answer: The system we need to use is:
A = T - 3
A = (2/3)*T
Solving this, we get:
In a bag, there are 9 tangerines and 6 apples.
Step-by-step explanation:
The question seems to be incomplete, by a quick online search i've found the complete question:
"A fruit stand sells bags of apples and tangerines. • Each bag has 3 fewer apples than tangerines. 2 • In each bag, the number of apples is 2/3 the number of tangerines..."
We know that:
A = number of apples in one bag
T = number of tangerines in one bag
We also know that:
"Each bag has 3 fewer apples than tangerines"
This can be written as:
A = T - 3
"In each bag, the number of apples is 2/3 the number of tangerines"
This can be written as:
A = (2/3)*T
Then we have a system of equations:
A = T - 3
A = (2/3)*T
This is the system of equations that can be used to solve for A and T, now let's solve this.
Because A means the same thing in both equations, then we can write:
A = T - 3 = A = (2/3)*T
Then:
T - 3 = (2/3)*T
We can solve this for T.
T - 3 = (2/3)*T
T - (2/3)*T = 3
(1 - 2/3)*T = 3
(1/3)*T = 3
T = 3/(1/3) = 3*3 = 9
This means that in each bag we have 9 tangerines in a bag.
Now we can use any of the two equations in the system to find the value of A.
I will use the first one:
A = T - 3
Now let's replace T by 9, then:
A = 9 - 3 = 6
A = 6
So there are 6 apples in a bag.

Answer:
a. (3x² - 2x - 5) units²
b. (x² - x) units²
c. (2x² - x - 5) units²
Step-by-step explanation:
a. Area of the frame = L*W
L = (x + 1) units
W = (3x - 5) units
Area of the frame = (x + 1)(3x - 5)
Apply distributive property
x(3x - 5) +1(3x - 5)
3x² - 5x + 3x - 5
Area of the frame = (3x² - 2x - 5) units²
b. Area of the picture = L*W
L = x units
W = (x - 1) units
Area of the picture = x(x - 1)
Apply distributive property
= x² - x
Area of picture = (x² - x) units²
c. Area of the frame that surrounds the picture = area of frame - area of picture
= (3x² - 2x - 5) - (x² - x)
= 3x² - 2x - 5 - x² + x (distributive property)
Add like terms
= 3x² - x² - 2x + x - 5
= 2x² - x - 5
Area of the frame that surrounds the picture = (2x² - x - 5) units²
