Angus Cut His Neighbors' Lawns For The Summer. By The End, He Had $325 In His Lawn-cutting Bank Account And He Paid A Total $75 For Gas. He Earned $10 For Ever Lawn He Mowed. How Many Lawns Did He Buy? A. N = 400 x 10 b n 250 x 10 c. N = 400 / 10 d. N = 250 / 10
Answer:
C. N = 400 / 10
Step-by-step explanation:
Lawn-cutting Bank Account = $325
Amount paid for gas = $75
Total amount earned = Lawn-cutting Bank Account + Amount paid for gas
= $325 + $75
= $400
Amount earned per every lawn he mowed = $10
How Many Lawns Did He mow?
Let N = number of lawns he mowed
N = Total amount earned / Amount earned per every lawn he mowed
N = 400 / 10
N = 40 lawns

David and his dad are building a room in the basement. They want the
room to have an area of 150 ft?. If one wall is 11.25 ft. long, how long must the other
wall be? Show your work.
find the value of x and find the value of the angle with a star in it
Answer:
x = 25
angle measure = 55
Step-by-step explanation:
The two angles are supplementary
2x+5+5x = 180
7x+5 = 180 subtract 5 from both sides
7x = 175 divide both sides by 7
x = 25 to find the angle with the star replace x with 25
25*2 + 5 = 55
does anyone know the surface area of this pyramid?
Answer:
217
Step-by-step explanation:
1/2 * 12 * 7 = 42 this is one side of the pyramid
4x for all sides = 168
add the bottom which is just a square 7*7 = 49
168 + 49 = 217

0.8 k - 20 = -60
what does ‘k’ equal?
Answer:
K = -50
Step-by-step explanation:
0.8(-50) - 20 = -60, because 0.8(-50) = -40, and when you subtract a negative you would "add" those numbers. So it would be 40 + 20 = 60, which would make it -60.
Answer:
k equals -50Step-by-step explanation:
0.8 k - 20 = -60
0.8k = -60 + 20
0.8k = -0
k = [tex]\frac{-40}{0.8}[/tex]
k = -50
 What is the volume of this cone?
Answer:
C) volume = 84.8 m³
Step-by-step explanation:
volume = 1/3πr²h = 1/3(3.14)(3²)(3) = 84.8 m³
Answer:
[tex]volume = 28.3m^3[/tex]
Step-by-step explanation:
[tex]volume \: of \: cone = \frac{1}{3} \times 3 \times 3.14 \times { 3}^{2} = 28.3{m}^{3} [/tex]
find the value of X
Answer:
x = [tex]\frac{91}{6}[/tex]
Step-by-step explanation:
Given 2 intersecting chords in a circle, then
The product of the parts of 1 chord is equal to the product of the parts of the other chord, that is
6x = 7 × 13 = 91 ( divide both sides by 6 )
x = [tex]\frac{91}{6}[/tex]

Suppose you know that the prices paid for cars are normally distributed with a MEAN or $17,000 and a STANDARD DEVIATION of $500. Use the EMPIRICAL RULE to find the percentage of buyers who paid
Complete question :
Suppose you know that the prices paid for cars are normally distributed with a MEAN or $17,000 and a STANDARD DEVIATION of $500. Use the EMPIRICAL RULE to find the percentage of buyers who paid between 15500 and 17000
Answer:
49.85%
Step-by-step explanation:
Mean = 17000
Standard deviation = 500
Obtain the Z score, which is the number of standard deviations from the mean :
((17000 - 17000) / 500) = 0
((15500 - 17000) / 500) = - 3
-3 to 3 = (3 standard deviations)
However,
The value here is (-3 to 0) ; which is only 3 standard deviations to the left.
3 standard deviation = 99.7% (empirical rule)
Since it is only (-3 to 0) ; which is only 3 standard deviations to the left. ; the percentage will be halved
99.7% / 2 = 49.85%
Hence, percentage of buyers who paid between 15500 and 17000 is 49.85%

A- 57 7/9 ft. 3
B- 11 2/3 ft 3
48 2/9 ft 3
28 2/3 ft 3
Answer:
A. 57 7/9
Step-by-step explanation:
First you multiply 13/3 (the length) by 10/3 (the width). You get 130/9. You then multiply 130/9 (the base) by 12/3 which equals 1560/27.
1560/27 can be simplified to 57.7777778, which in turn converts to 57 7/9.
57 7/9 is the final answer.

Solve the equation below for m.
3
Answer: 30
Step-by-step explanation:
3(0.3m + 6) + m =75
(0.3 x 3 = 0.9)
(6 x 3 = 18)
0.9m + 18 + m = 75
0.9m + m + 18 = 75
(m=1)
1.9m + 18 = 75
1.9m = 75 - 18
1.9m = 57
m = 57÷ 1.9
m = 30
