First find the perimeter of the rectangle
P = 2(l+w) where l is the length and w is the width
P = 2( 5x-1+x)
Combine like terms
P = 2( 6x-1)
P = 12x -2
Find the perimeter of the triangle
P = s1 + s2 +s3 where s is the side length
P = 5x+12+ 6x+7
Combine like terms
P = 11x+19
We are told the perimeters are equal
12x-2 = 11x+19
Subtract 11x from each side
12x-2 -11x = 11x+19-11x
x-2 = 19
Add 2 to each side
x-2+2 = 19+2
x = 21
The side lengths of the rectangle are
x=21 and 5x-1 = 5*21 -1 = 105-1 = 104
We can find the area
A = l*w where l is the length and w is the width
A = 21 * 104

Jamie earned 18 more points on her test than Paul earned. Their points add up to 60. How many points did each student earn?
Answers
Answer:
Paul earned 21 points and Jamie earned 39 points.
Step-by-step explanation:
So, you start off with 60-18=42. Now, you have how much they earned minus Jamie's bonus 18. So, now that they have earned the same amount, you divide 42/2=21. So, now you know how many points Paul earned, 21, and now you just have to add the points Jamie earned that Paul didn't back to their score. 21+18=39

A population has a mean of 128 and a standard deviation of 32. Suppose a sample of 64 is selected. What is the probability that the sample mean will be within +- 5 of the population mean?
Answers
The probability that the sample mean will be within +- 5 of the population mean is 0.7888.
What will the probability be?In this case, within 5 will be:
= 128 ± 5 = 123, 133
The probability will be:
P(123 < x < 133)
= P(123 - 128))4 =(133 - 128)/4
= P(-1.25< Z < 1.25 )
= P(Z < 1.25) - P(Z < -1.25 )
Using z table,
= 0.8944 - 0.1056

An investigation of a number of automobile accidents revealed the following information:15 accidents involved alcohol and excessive speed27 accidents involved alcohol.13 accidents involved excessive speed but not alcohol22 accidents involved neither alcohol nor excessive speedHow many accidents were investigated? ** note: Let the universal set U be the set of all automobile accidents. Use the information provided to create a Venn diagram containing 2 subsets. Let A be the set of accidents involving alcohol and S be the set of accidents involving excessive speed. **
Answers
To solve this type of question we should use the Venn diagram
Let me draw it and show you where we will put each number given
Since there are 15 accidents involved alcohol and excessive speed
Then we should put 15 in the common part of the 2 circles
Since there are 27 accidents involved alcohol
That means 27 = alcohol only + alcohol and excessive speed
Then to find alcohol only we should subtract 15 from 27 to get the number of alcohol only
27 - 15 = 12
Since there are 13 accidents involved excessive speed but not alcohol
That means the excessive speed only is 13
Let us put it in the Venn diagram
Since there are 22 accidents involved neither alcohol nor excessive speed
That means we will put this number outside the circles inside the rectangle
To find the total number of accidents we will add all the numbers in the figure
[tex]\begin{gathered} T_{acc}=12+15+13+22 \\ T_{acc}=62 \end{gathered}[/tex]Then there are 62 accidents in this investigated

The domain and range for the relation is [-∞, ∞] and [0,-3], and both of them can be described by interval notation .
Since the graph given to us present a relation or a function, The domain and range of a function are the set of all the inputs and yield a function that can grant separately. The domain and range are vital viewpoints of a function. The domain takes all the conceivable input values from the set of real numbers and the range takes all the yield values of the function. In simple words, the domain is the set of all "x" values and the range is the set of all "y" values in a set of ordered sets and the requested sets are composed as in the form (x, y) or [x,y]
for the given the points are : (0,-3),(1,-3),(2,-3),(3,-3),(4,-3),(5,-3),(-1,-3)(-2,-3),(-3,-3),(-4,-3),(-5,-3)

Answers
Hello there. To solve this question, we'll have to remember some properties about cylinders.
We want to determine the surface area of the following cylinder:
In this case, the surface area comprehends the bottom, the top and the lateral area of the cylinder.
For a cylinder with height h and radius R, it is easy to show that
By redrawing the cylinder as the following figures:

The area of the circles are given as

Answer:
Jonah has 15 dimes.
Step by step explanation:
Since question 7, tells us that we have to use the following equations to solve the system:
Let x be the nickels
Let y be the dimes
[tex]\begin{gathered} x+y=20\text{ (1)} \\ .05x+.10y=1.75\text{ (2)} \end{gathered}[/tex]We can use the substitution method to solve the system, isolate y in equation (1), and then plug it into equation (2)

The coordinates of the triangle is given as:
A(1, 2), B(3, 2), C(2, 4) is rotated 90 degree
