Answer:
m = rise / run = 1/7
Step-by-step explanation:
Recall that the slope of a line is m = rise / run.
Here we look at x first (to calculate the run): x begins at -7 and ends at 0. Thus, the run is 0 - (-7), or 7.
Now look at how y behaves (find the rise): y begins at 0 and ends at 1. Thus, the rise is 1.
Therefore the slope of the line connecting the two poings given is
m = rise / run = 1/7
Three quarts of a latex enamel paint will cover about 120 square feet of wall surface. How many quarts are needed to cover 161 square feet of kitchen wall and 119 square feet of bathroom wall? Nothing quarts of a latex enamel paint are required
Answer:
7 quarts
Step-by-step explanation:
We can solve this problem by using the rule of three. As seen in the picture below we need to find the X. We do this by multiplying 161 sq. ft. diagonally by 3 quarts and then dividing by 120 sq. ft. This will give us the number of quarts needed for the kitchen wall. Then we simply repeat the process for the bathroom wall and we are done. Like so ...
[tex]\frac{161 sq. ft. * 3 quarts}{120 sq. ft.} = x[/tex]
[tex]4.025 quarts = x[/tex]
[tex]\frac{119sq. ft. * 3 quarts}{120 sq. ft} = x[/tex]
[tex]2.975 quarts = x[/tex]
Therefore we need 4.025 quarts for the kitchen wall and 2.975 quarts for the bathroom wall ... making that a total of 7 quarts.

How do the measures of the side lengths of AABCcompare with those of AA'B'C' when AA'B'C' coincides with the other three triangles?
What can you say about the preservation of the side lengths of a shape during a rotation?
Answer:
The angle measures of ABC and the other triangles are the same measures, and the side lengths in ABC and the other triangles are the same lengths when ABC coincides with them. It appears that angle measures and side lengths are both preserved when ABC is rotated.

The point-slope form of the equation of the line that passes through (-9, -2) and (1, 3) is y – 3 = {(x - 1). What is the
slope-intercept form of the equation for this line?
Oy=1x+2
Oy={x-4
O y = x + 3/2
Oy=2x-
2.
Option A is the correct answer, y = x + 2
y - 3 = x-1
If you bring the 3 to the R.H.S, it becomes y = x + 2
If you substitute the values,
3 = 1 + 2
3 = 3
Thus, e equation is correct
The slope-intercept form of the equation for this line is y = 1/2 x + 5/2
First, we need to get the slope of the equation passing through the coordinate (-9, -2) and (1, 3)
m = 3+2/1+9
m = 5/10
m = 1/2
The equation in point slope form is given as y - 3 = 1/2(x - 1)
2(y - 3) = x - 1
Write in slope intercept form
2(y - 3) = x - 1
2y - 6 = x - 1
2y = x + 5
y = 1/2 x + 5/2
Hence the slope-intercept form of the equation for this line is y = 1/2 x + 5/2

volume =160.875m, length =6.5m, height =5.5m, breadth =?
Answer:
b = 4.5 m
Step-by-step explanation:
Since we have 2 sides of the shape and the total volume, we can easily find the measurement of the third side which is the breadth by:
volume = 160.875
v = l×h×b
160.875m=(6.5m)×(5.5m)×b
160.875m=35.75b
b = 4.5 m
Answer:
4.5m
Step-by-step explanation:
v=lbh
b=v/lh
= 160.875/(6.5×5.5)
=160.875/35.75
=4.5m

Malik's arts and crafts shop has a bolt of crimson velvet 32 meters long. A customer came in during the morning and bought 120 centimeters of the velvet. Another customer bought an additional 14 meters during the afternoon. How much crimson velvet does Malik's shop have left? Write the answer in centimeters. centimeters of velve
Given:
Malik's arts and crafts shop has a bolt of crimson velvet 32 meters long.
Velvet purchased by first customer = 120 centimeters
Velvet purchased by second customer = 14 meters
To find:
The remaining velvet in Malik's shop.
Solution:
We know that,
1 meter = 100 cm
Using this conversion, we get
32 meter = 3200 cm
14 meter = 1400 cm
Now,
Remaining velvet in Malik's shop = (3200 - 120 - 1400) cm
= 1680 cm
Therefore, the remaining velvet in Malik's shop is 1680 cm.

Your sister is selling Girl Scout cookies that cost $3.50 per box. Your family bought 6 boxes. How many more boxes of
cookies does your sister need to sell to raise $196?
Answer:
She needs $175.
Step-by-step explanation:
3.50 X 6= $21. (196-21=175)
So since she needs $196 and per box it would be $3.50 and 6 boxes is $21 total, she would need to sell 56 boxes total to get to her goal, but since her parents bought 6 boxes already she will only need 50 more.

The following is a factor of the polynomial is x+2.
What is Factor theorem?Factor theorem is a special kind of the polynomial remainder theorem that links the factors of a polynomial and its zeros.
The factor theorem removes all the known zeros from a given polynomial equation and leaves all the unknown zeros. The resultant polynomial has a lower degree in which the zeros can be easily found.
As per the factor theorem, (y – a) can be considered as a factor of the polynomial g(y) of degree n ≥ 1, if and only if g(a) = 0. Here, a is any real number. The formula of the factor theorem is g(y) = (y – a) q(y). It is important to note that all the following statements apply for any polynomial g(y):
(y – a) is a factor of g(y).g(a) = 0.The remainder becomes zero when g(y) is divided by (y – a).The solution to g(y) = 0 is a and the zero of the function g(y) is a.Given:
f(x)=x³ + 12x² + 9x - 22
To the above equation (x + 2) is a factor of x³ + 12x² + 9x - 22.
As,
f(-2)= (-2)³ + 12(-2)² + 9(-2) - 22
f(x)= -8 + 48 -18 -22
f(x)= 40 -40
f(x) = 0
Hence, the factor of x+2

Step-by-step explanation:
Account A and Account B both have a principal of $2,000 and an annual interest rate of 2%. No additional deposits or withdrawals are made. Account A earns simple interest. Account B earns interest compounded annually. Compare the amounts in the two accounts after 20 years. Which earns more interest? How much more?
After 20 years, account (A or B) will have earned $____ more.
Answer:
Account B earns more interest.
After 20 years, account B will have earned $171.89 more.
Step-by-step explanation:
Let's calculate the total for each account.
Account A:
Account A earns simple interest. We know that the principal value is $2000 and the interest rate is 2% or 0.02. We can use the simple interest formula:
[tex]A=P(1+rt)[/tex]
Where A is the future value, P is the principal, r is the rate, and t is the time in years.
So, let's substitute 2000 for P, 0.02 for r, and 20 for t. This yields:
[tex]A=2000(1+0.02(20))[/tex]
Multiply and add:
[tex]A=2000(1+0.4)=2000(1.4)[/tex]
Multiply. So, the total amount of money in Account A after 20 years is:
[tex]A=\$2800[/tex]
Since we initially deposited $2000 and our total is now $2800, this means that we earned an interest of [tex]2800-2000=\$ 800[/tex]
Account B:
Account B earns compound interest. Like Account A, Account B has a principal value of $2000 and the interest rate is 2% or 0.02. We also know that it's compounded annually, so once per year. We can use the compound interest formula:
[tex]B=P(1+\frac{r}{n}})^{nt}[/tex]
Where B is the future value, P is the principal, r is the rate, n is the times compounded per year, and t is the time in years.
So, let's substitute 2000 for P, 0.02 for r, n for 1 (since it's compounded annually), and t for 20. This yields:
[tex]B=2000(1+\frac{0.02}{1})^{(1)(20)}[/tex]
Simplify this to acquire:
[tex]B=2000(1.02)^{20}[/tex]
Evaluate. Use a calculator. So, after 20 years, the amount of money in Account B is:
[tex]B\approx\$2971.89[/tex]
Since our principal was $2000, this means that we earned an interest of approximately [tex]2971.89-2000=\$ 971.89[/tex].
So, Account A earned an interest of $800 and Account B earned an approximate interest of $971.89.
So, Account B earned more interest.
And it earned [tex]971.89-800=\$ 171.89[/tex] more than Account A.
And we're done!
