Question on the image
Answer:
m =10
Step-by-step explanation:
Barry = m
S = m+5 since they are 5 years older
A = m-3 since they are 3 years younger
Add to get the total
m + (m+5) + (m-3) = 32
Combine like terms
3m +2 = 32
Subtract 2 from each side
3m+2-2 = 32-2
3m = 30
Divide by 3
3m/3 = 30/3
m =10

△ABC is reflected across the y-axis on a coordinate plane, resulting in △A′B′C′. If the measure of ∠A is 50 degrees, what is the measure of ∠A′?
Answer:
Reflections across the line y = x
A reflection across the line y = x switches the x and y-coordinates of all the points in a figure such that (x, y) becomes (y, x). Triangle ABC is reflected across the line y = x to form triangle DEF. Triangle ABC has vertices A (-2, 2), B (-6, 5) and C (-3, 6).
At the end of a snow storm, Damian saw there was a lot of snow on his front lawn.
The temperature increased and the snow began to melt at a steady rate. There was a
depth of 15 inches of snow on the lawn when the storm ended and then it started
melting at a rate of 0.75 inches per hour. Make a table of values and then write an
equation for S, in terms of t, representing the depth of snow on Damian's lawn, in
inches, t hours after the snow stopped falling.

Given the function below, if f(x) = -1, find the value of x.
f (x) = 4x + 11
soln
given,
f(x) = 1

f(x) = 4x+11
or, -1 =4x +11
or,4x = 11+1
or, 4x = 12
or, x. =12/4
or x. = 3
Therefore, The value of x is 3.

The Gutierrez family and the Kim family both have pools. The Gutierrez family is filling their
pool, which is modeled by the equation =
1
2 + 1. The Kim family is draining their pool,
which is modeled by the equation = −1.25 + 5. In both equations, represents the time in
hours and represents the depth of the water in the pool in feet. These two situations can be
described by the following system of equations:
y = 1/2x + 1
y= -1.25x + 5
Answer:
x = 2.285 hours
y = 2.1425 feet
Step-by-step explanation:
Let us say that y represents the depth of the pool in feets and x represents the time in hours
The two set of equations are
y = 1/2x + 1
y= -1.25x + 5
Solving the above two equations we get
Subtracting eq (1) from eq (2), we get -
y-y = -1.25 x -0.5 x + 4
0 -1.75 x + 4
x = 4/1.75
x = 2.285 hours
y = 0.5 * 2.285 + 1
y = 2.1425 feet

Answer:

Step-by-step explanation:
The Smith family plans to purchase a new house in 4 years, and they want to make a down payment of 25% of the estimated purchase price of $250,000. Find the amount they need to invest to make the down payment if funds earn 12% compounded quarterly.
Answer:
The Smith Family paid $50, 820 as down payment.
Step-by-step explanation:
Total purchase price the Smith Family Paid = $231,000
Percentage of the amount paid in Down Payment = 22%
This means 22% of the total purchase price was paid in down payment.
The formula to calculate percentage in this case will be:
Percentage Price = (Amount Paid in Down Payment/Total Price) x 100%
Using the values, we get:
22% = (Amount Paid in Down Payment) / 231,000 x 100%
0.22 = (Amount Paid in Down Payment) / 231,000
Amount Paid in Down Payment = 0.22 x 231000 = $50, 820
This means, The Smith Family paid $50, 820 as down payment.
Hope this answer helps you :)

A local charity holds a carnival to raise money. In one activity, participants make a $3 donation for a chance to spin a wheel that has 10 spaces marked with the values 0, 1, 2, 5, and 10. The participant wins the dollar amount marked on the space on which the wheel stops. Let X represent the value of a spin. The distribution of X is given in the table.
A 2-column table with 5 rows. Column 1 is labeled value of a spin with entries 0, 1, 2, 5, 10. Column 2 is labeled probability with entries 0.4, 0.2, 0.2, 0.1, 0.1.
What is the median of the distribution?
1
1.5
2
2.1
Answer:2
Step-by-step explanation:
The median of the probability distribution given in the table is 1.
Given that X, the value of a spin and the corresponding probability distribution.
X : 0 1 2 5 10
P(X) : 0.4 0.2 0.2 0.1 0.1
CF : 0.4 0.6 0.8 0.9 1
So the sum of the cumulative frequency = 1
We have to find the value where the half of the cumulative frequency lies in.
1/2 = 0.5
0.5 lies in between 0.4 and 0.6.
The value of the spin that corresponds to 0.6 is 1.
So the median of the distribution is 1.
