Answer:
25 years
Step-by-step explanation:
Given data
Principal P= $2000
Interest rate r= 6%
FInal amount A=$5,000
The simple interest formula is given as
A=P(1+rt)
substitute and solve for t
5000=2000(1+0.06*t)
5000=2000+120t
5000-2000=120t
3000=120t
t= 3000/120
t= 25 years
Hence, for a simple interest investment, she will be 25 years

Answer:
a concave lens is exactly the opppostie with outer surfaces curving inward, so it makes parallel light rays curve outward or diverge. That's why concave lenses are sometimes called diverging lenses. ... The distance from the center of the lens to the focal point is, again, the focal length of the lens.
Step-by-step explanation:
4(x + 7) = 38
can you help me find the solution t the equation
Step-by-step explanation:
Given
4(x + 7 ) = 38
4x + 28 = 38
4x = 38 - 28
4x = 10
x = 10 / 4
x = 5 / 2

what is the y intercept of 2y - 2x = 8
Answer:
Step-by-step explanation:
Write in y = mx + b form
here, b ----> y intercept
2y - 2x = 8
2y = 2x + 8 {Divide the equation by 2}
[tex]\frac{2y}{2}=\frac{2x}{2}+\frac{8}{2}\\[/tex]
y = x + 4
y-intercept = 4

Which of the following is true?
choice b.
choice c.
choice d.
choice a.
Answer: THE ANSWER IS
Determine if the relation is a function.
The relation is a function.
Find the domain and range.
Domain:
{−3, −1, 5, 8}
Range:
{−6}
Graph.
{(−3,−6), (−1, −6), (5, −6), (8, −6)}
Determine if the relation is linear.
The relation is linear
Find the inverse.
( − 6 , − 3 ) , ( − 6 , − 1 ) , ( − 6 , 5 ) , ( − 6 , 8 )
Step-by-step explanation: IT'S NOT A OR D.. ig
1: Recall that a function from a set to a set is a relation that assigns to each element in the set exactly one element in the set . The set is the domain (or set of inputs) of the function and the set contains the range (or set of outputs).
The general characteristics of functions are:
A. Each element in A must be matched with an element in B.
B. Some elements in B may not be matched with any element in A.
C. Two or more elements in A may be matched with the same element in B.
D. An element in A (the domain) can not be matched with two different elements in B.
________________________________________________
Solving this problem we have:
1. The mapping diagram is represented in Figure 1. As you can see this is a function. Each element in A is matched with an element in B. All the elements in A are matched with the same element in B. So, this fulfills with the definition of function.
2. The mapping diagram is represented in Figure 2. This is not a function. Notice that an element in A (the domain) is matched with two different elements in B, that is, -8 is matched with -6 and 1.
2: #1) This is a function.
#2) This is not a function.
(The mapping diagrams are not present to match to these.)
Explanation:
A function is a relation in which each element of the domain is matched to no more than one element of the range; in other words, no x gets mapped to more than 1 y.
In #1, no x is mapped to more than 1 y, so it is a function. However, in #2, -8 is mapped to both -6 and to 1; this x is used more than once, so this is not a function.

4: Answer:
Option D is correct.
The relation {(-8, -6) (-5, 2) (-8, 1) (7, 3)} is not a function.
Step-by-step explanation:
Given the relation: {(-8, -6) (-5, 2) (-8, 1) (7, 3)}
Domain is the set of all possible inputs of a relation i.e { -8, -5 , -8 , 7}
Range is the set of output values of a function i.e, {-6, 2 , 1 , 3}
The mapping as shown below in the figure:
A function is a relation in which every element of the domain is matched to not more than one element of the range.
In other words, we can say that ,no value of x gets mapped to more than 1 value of y.
Since, from the mapping you can see that the domain value -8 paired with -6 and 1; as x is used more than once.
Therefore, this relation is not a function

Bethany can mow her family’s lawn in 4 hours. Her brother Colin can mow the lawn in 3 hours. Which equation can be used to find the number of hours, x, it would take for Bethany and Colin to mow the lawn together?
Answer:
Step-by-step explanation:
t/4+t/3=1
(3t+4t)/12=1
7t/12=1
7t=12
t=12/7
x=(12/7)hours
Answer:
1/4 + 1/3 = 1/x
Step-by-step explanation:
"Bethany can mow her family’s lawn in 4 hours."
In 1 hour, she does 1/4 of the job.
"Her brother Colin can mow the lawn in 3 hours."
In 1 hour, he does 1/3 of the job.
When they work together, in 1 hour they do 1/4 + 1/3 of the job.
When they work together, they can mow the lawn in x hours.
In 1 hour, they do 1/x of the job. This means that 1/4 + 1/3 must equal 1/x.
1/4 + 1/3 = 1/x

What is the probability of rolling an even number on a number cube containing numbers 1 through 6? *
Answer:
[tex]\frac{1}{2}[/tex] or 50%
Step-by-step explanation:
Cube has 6 sides = 3 odds and 3 even
probability is found using
[tex]\frac{number of favourable outcomes}{number of total outcome}[/tex] which is [tex]\frac{3}{6} or \frac{1}{2}[/tex]
1/2 = 50%
please hlelp meeeeeeeeeeeeee i need help
Answer:
3/4
Step-by-step explanation:
Total number of cases = 8 [1,2,4,2,5,3,1,2]
No. of number less than 4 = 6 [1,2,2,3,1,2]
Probability = 6/8 = 3/4
Answer: 75%
Step-by-step explanation:
Well there are 8 possibilities every time you spin. The chance is 6/8 that you land on a number less than 4, if you spin it once (since 6 out of the 8 possibilities are less than 4). So you just have to divide 6/8 which is 0.75. Multiply by 100 (move the decimal over 2 times to the right) to get the percentage which is 75%.

a taxi company charges passengers 1.75 for a ride,?
a taxi company charges passengers 1.75 for a ride, no matter long the ride is, and an additonal $0.40 for each mile traveled. the rule c=0.40m+1.75 describes the relationship between the number of miles M and the total cost of the ride c.
what is the charge for 2.7 mile ride
A. 5.13
B. 1.08
C. 2.15
D. 2.83
Favorite Answer
D 2.83
c = 0.4. * 2.7 + 1.75
=> c = 2.83
Step-by-step explanation: It Looks Like The Answer is D
c=0.40(2.7)+1.75=$2.83 so $2.83 is the answer
1.75+(2.7*.4)=
1.75+1.08=
2.83
The answer is $2.83

The function y= -0.2 + 0.5 represents the percent y (in decimal form) of battery power remaining x hours after you turn on a laptop computer.
A. Identify and intercept the x- intercept
B. Identify and intercept the y-intercept
Answer:
A
Step-by-step explanation:
intercept the x- intercept
Answer:
Step-by-step explain
x-intercept: 2.8 hours
y-intercept: 0.7 . . . . fraction of power remaining
Step-by-step explanation:
The equation is in slope-intercept form, so the y-intercept can be read directly: 0.7.
To find the x-intercept, set y=0 and solve for x:
0 = -0.25x +0.7
0.25x = 0.7 . . . . . add .25x
x = 2.8 . . . . . . . . . multiply by 4 (that is, the reciprocal of 0.25)
The x-intercept is 2.8; the y-intercept is 0.7.
Simplify fully e x e x e x f/ e x e x f x f
Given:
The given expression is
[tex]\dfrac{e\times e\times e\times f}{e\times e\times f\times f}[/tex]
To find:
The simplified form of given expression.
Solution:
We have,
[tex]\dfrac{e\times e\times e\times f}{e\times e\times f\times f}[/tex]
The common factors in numerator and denominator are e, e, f.
Cancel out the common factors.
[tex]=\dfrac{e}{f}[/tex]
Therefore, the required expression is [tex]\dfrac{e}{f}[/tex].
