Diragio Lawn Care cuts lawns every week. Each lawn uses 34 of a tank of gas when it is cut (on average). How much gas is used if 10 lawns are cut in one week? Choose two answers that represent the solution.
Answer:
7.5 tank oil will be used
Step-by-step explanation:
Amount of gas used to cut one lawn (on an average) = 3/4 of a tak
Given ,
In a week , ten such lawns are cut

= 3/4* 10
= 7.5 tank
What value of x makes the following equation true? ( 8th grade math )
Answer: 4
Step-by-step explanation:
2(x+7) = x + 18
2x + 14 = x + 18
x + 14 = 18
x = 4
Answer:
C. 4
Step-by-step explanation:
[tex]2(x + 7) = x + 18[/tex]
[tex]2(x+7) = 2x + 2×7[/tex]
[tex]=2x+14[/tex]
[tex]2x + 14 = x + 18[/tex]
[tex]2x + 14-x=18[/tex]
[tex]2x - x = 18 - 14[/tex]
[tex]x=18-14[/tex]
[tex]x = 4[/tex]

Find the surface area of a sphere with radius 9 using the formula SA=4nr2
Leave answer in terms of n
A. 20 n units2
B. 25 n units2
C. 100 n units2
Answer:
972 u³
Step-by-step explanation:
The radius is 9 . We can use formula ,
⇒ V = 4/3 π r³
⇒ V = 4/3 × π × 9³
⇒ V = 4 × π × 81 × 3
⇒ V = 972 unit³

Answer:
Rico Spent $6.50 on each car.
Step-by-step explanation:If you divided 52 by 8 you get 6.5 in money it would be $6.50.
My answer is reasonable because my estimate ÷ 10 = $6.50
Answer:
The answers are: 6.5$ , divided by, and 5$
Step-by-step explanation:
In order to figure out the price of each toy car, we must divide 52/8 (the total price of the toy cars divided by the number of the cars) which equals to 6.5, meaning that each toy car costs 6.5$, since they all have the same price. We know that this is a reasonable price because say we were to estimate, meaning we'd take a guess without doing any calculations. Let's say we paid 50$ in total, which is easily divided by 10, if we were to round up both numbers, we'd get 5$ each. That's close to the true answer, making it reasonable to take such a guess.
Competency: Write the linear equations Ax + By = C. Give the value of A,B, and C,.
Answer:
see explanation
Step-by-step explanation:
(1)
y = - x + 4 ( add x to both sides )
x + y = 4
with A = 1, B = 1, C = 4
(2)
y = 5x + 7 ( subtract y from both sides )
0 = 5x - y + 7 ( subtract 7 from both sides )
- 7 = 5x - y , that is
5x - y = - 7
with A = 5, B = - 1, C = - 7
----------------------------------------------------------
(1)
2x + y = 9 ( subtract 2x from both sides )
y = - 2x + 9
with m = - 2, c = 9
(2)
5x + 2y = 7 ( subtract 5x from both sides )
2y = - 5x + 7 ( divide terms by 2 )
y = - [tex]\frac{5}{2}[/tex] x + [tex]\frac{7}{2}[/tex]
with m = - [tex]\frac{5}{2}[/tex] , c = [tex]\frac{7}{2}[/tex]

find the volume figure below
A. 45 mm3
B. 45 mm2
C. 3,375 mm2
D. 3,375 mm3
Step-by-step explanation:
its either C or D and yup sure
Answer:
3,375 mm³
Step-by-step explanation:
To find the volume of a cube or rectangular prism, multiply the length, width, and height of the figure. In this case, the figure is a cube, so all the side lengths are equal. So, all you have to do is multiply 15 three times.
15 · 15 · 15 = 3,375
The answer is D, 3,375 mm³. Use the cubed symbol to show volume :) Good luck

Determine whether the conclusion is valid. Explain. You want to determine the number of students in your school who have visited a science museum. You survey 50 students at random. Twenty have visited a science museum, and thirty have not. So, you conclude that 40% of the students in your school have visited a science museum.
Answer: The conclusion is valid
Step-by-step explanation:
Number of students surveyed = 50
Number of students who visited a science museum = 20
Number of students who haven't visited a science museum = 30
Percentage of student that have visited a Science museum:
= 20/50 × 100
= 40%
The conclusion is valid based on the calculation.
