Answer:
8/10+7/9+39/90
Step-by-step explanation:
expressing something in the form p/q means basically make it a fraction.
.8 = 80/100
.7bar= .77777777777 (7/9)
0.43 (bar on 3 only is)= 0.433333333333333
how to make a fraction for .777777bar
10x = 7.777777777
X = .7777777777
subtract 10x-x
we get 7/9 for .7777 (10x-x = 9 thats the denominator and, 7.7777-.7777 = 7.)
how to make a fraction for .43bar for 3 only
100x = 43.3333333333
10x = 4.33333333333
100x-10x = 43-4
43-4 = 39, and the 333333333 cancel out 39/90

Step-by-step explanation:
3 + [tex]\sqrt{16}[/tex] ÷ 2 * 4
work for the root first
3 + [tex]\sqrt{4*4}[/tex] ÷ 2 * 4
3 + 4 ÷ 2 * 4
now divide 4 by 2
3 + 2 * 4
then do multiplication
3 + 8
11
Answer:
11
Step-by-step explanation:
Following the order of operations in PEMDAS
Given
3 + [tex]\sqrt{16}[/tex] ÷ 2 × 4 ← evaluate the square root
= 3 + 4 ÷ 2 × 4
When multiplication appear on the same line evaluate from left to right
= 3 + 2 × 4
= 3 + 8

Which formula will correctly calculate the length of side, t, in the triangle?
Answer:
t = [tex]\sqrt{r^2 + s^2}[/tex]
Step-by-step explanation:
Below is the following calculation:
It is given that the one side of the triangle is t. Thus, let the other sides are "r" and "s". Thus, the best way to find the side of a triangle is to use the Pythagorean theorem. Here, let t is the hypotenuse.
Below is the formula:
t = [tex]\sqrt{r^2 + s^2}[/tex]

Find the slope of the line. Describe how one variable changes in relation to the other. How did you find this?
A, 2/3; the amount of water decreases by 2 gallons every 3 minutes.
B, - 2/3; the amount of water decreases by 2 gallons every 3 minutes.
C, - 3/2; the amount of water decreases by 3 gallons every 2 minutes.
D, -1; the amount of water decreases by 1 gallon per minute.
According to the given information, the slope of the line is -1.
What is slope ?In mathematics, slope is a measure of how steep a line is, or how much y (vertical) changes for a given x (horizontal) change. It is represented by the letter "m" and is calculated as the change in y divided by the change in x, or rise over run. The slope can be positive, negative, zero, or undefined.
According to given information :The answer is D, -1; the amount of water decreases by 1 gallon per minute.
To find the slope of the line, we need to use the slope formula:
slope = (change in y)/(change in x)
In this case, the change in y represents the change in the amount of water, and the change in x represents the change in time.
Option A says that the slope is 2/3, which means that for every 3 minutes, the amount of water decreases by 2 gallons. This is incorrect because as time increases, the amount of water should decrease, so the slope should be negative.
Option B says that the slope is -2/3, which means that for every 3 minutes, the amount of water decreases by 2 gallons. This is the same as option A but with a negative slope, which is correct because the amount of water decreases over time.
Option C says that the slope is -3/2, which means that for every 2 minutes, the amount of water decreases by 3 gallons. This is incorrect because the amount of water should decrease by the same amount every minute.
Option D says that the slope is -1, which means that for every minute, the amount of water decreases by 1 gallon. This is the correct answer because it describes a constant rate of change in the amount of water over time.
Therefore, according to the given information, the slope of the line is -1.

Answer:
v = 10
Step-by-step explanation:
Answer:
v = 6
Step-by-step explanation:
8 v - 4 ( v + 8 ) = 8
8 v - 4 v - 32 = 8
4 v - 32 = 8
4 v = 8 + 32
4 v = 40
v = 40 / 4
v = 10

Select the graph of the solution. Click until the correct graph appears. 3x + 1 < 7
Answer:
x < 2
Step-by-step explanation:
Let's actually solve the given inequality 3x + 1 < 7. First we want to combine the constants into one: 3x < 6. Solving for x, we get x < 2.
The graph you have chosen as your answer is correct. x does not equal 2, but rather is less than 2, as the given inequality states. Since x is less than 2, we start at the (open) circle at 2 and move to the left.
find the area of 72 by 108 inches in square yards? pls show work
Step-by-step explanation:
72 times 108 = 7776 sq inches
to convert inches to yds divide by 36
7776/ 36 = 216 sq yds
Answer: 6 yards^2
Step-by-step explanation:
first lets find the area of the space in inches and then convert the total to square yards :)
area = length * width
A = 108 * 72 = 7776 inches^2
now lets convert it
there are 1296 inches in a yard, so we divide 7776 by 1296 to find the number of square yards
7776 / 1296 = 6
so the area of the space is 6 yards^2

geometric sequence multiplies.
hope this helps
Answer:
Third option or 3,9,27,81
Step-by-step explanation:
A geometric sequence is a sequence where the term multiplies by the last term to make the next term.
In these options, we can clearly see the second and fourth one are not geometric as their relationship is not by multiplying.
The first option is also wrong since 4*-16 is -64, not 64.
That leaves the third option. 3*9 = 27, 9*27 is 81. Therefore, it is the third option

A dolphin swims 665,280 feet in 3 hours. Use the formula d = rt, where d represents distance, rrepresents rate, and t represents time to answer the
following questions. Show your work
Part A: Rearrange the distance formula, d = rt, to solve for rate. (2 points)
Part B: Find the dolphin's rate in feet per hour. (3 points)
Part C: Find the dolphin's rate in miles per hour. (3 points)
Part D: Which unit, feet, or miles, makes more sense to use in this scenario, and why?
Answer:
A) r=d/t
B) 221,760 feet per hour
C) 42 miles per hour
D) in this scenario feet per mile makes more sense since the distance is listed in feet.
Step-by-step explanation:
A) you solve for r by divided both sides of the equation by (t)time
B) you take your formula r=d/t and substitute the values of (d) and (t) with 665,280 feet and 3 hours.
C) convert feet to miles by dividing the given amount of feet by 5280 since there are 5,280 feet in 1 mile
D) use feet to make the calculations easier and to avoid making a mistake in converting feet to miles
