Answer:
Here,
Volume of pyramid (V) = 1/2 ×A×H
Given, V= 60 , H= 9
Now place the value of V and H in :
V= 1/2 ×A×H
60= 1/2 ×A × 9
60×2= 9A
120/9 = A
Hence, A= 120/9

Alex has twice as much money as Jennifer. Jennifer has $6 less than Shannon. Together they have $54. How much money does each have?
Answer:
Alex has twice as much money as Jennifer.
a = 2j
Jennifer has $6 less than Shannon.
j = s-6
j+6 = s
All together the three friends have $54.
a + j + s = 54
Replace a and s
2j + j + (j+6) = 54
4j = 54 - 6
4j = 48
j = 48/4
j = 12
Jennifer has $12
Alex= 2*12 = $24
Shannon = 24+12+s = 54
= 36+s = 54
s = 18
Shannon has $18
A grocery delivery service has 22 members. Each member pays monthly dues of $12.80
on the first day of the month,9 members paid
their dues. The remaining members paid
their dues on the third day of the month. How much
money was
collected in dues on the
(third days of the month?
A.115.20
B.232
C.166.40
D.131.84
Answer:
C
Step-by-step explanation:
If 9 members paid on the first day, this means they did not pay on the third day
The remaining people (everyone but the 9) paid on the third day
Therefore we must subtract to find out how many members paid on the third day
22 - 9 = 13
Each of the 13 members paid $12.80 which means we must multiply
13 × 12.80 = 166.40
In total, the grocery store collected $166.40 on the third day of the month

b. Identify and interpret the x- and y-intercepts.
Answer:
a) 3x+7y
Step-by-step explanation:
Sorry I don't know the answer to question B
Hope this helps
The equation models the total points scored in the game as 42 = 3x + 7y, and the x-intercept and y-intercept are 14 and 6.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
A high school football team scores a total of 42 points by scoring touchdowns and field goals.
From the data given in the question:
42 = 3x + 7y
Here x represents the number of field goals and y represents the number of touchdowns.
For x-intercept:
Plug y = 0
3x = 42
x = 14
For y-intercept:
Plug x = 0
7y = 42
y = 6
Thus, the equation models the total points scored in the game as 42 = 3x + 7y, and the x-intercept and y-intercept are 14 and 6.

A driver of a car stopped at a gas station to fill up his gas tank. He looked at his watch, and the time read exactly 3:40 p.M. At this time, he started pumping gas into the tank. At exactly 3:44, the tank was full and he noticed that he had pumped 10.2 gallons. What is the average rate of flow of the gasoline into the gas tank?
Answer:
2.55gallons.minStep-by-step explanation:
given that the initial time before pumping is 3:40 p.M.
after pumping the time reads 3:44, hence he use 4 min to fill his tank
time taken=4 min
also given is that had pumped 10.2 gallons
the capacity of tank= 10.2gallon
Then the average rate of pump is
average rate= capacity of tank/time taken
average rate= 10.2/4min
average rate=2.55gallons.min

A gym's membership in 2012 was 9,300. The current membership is 2,800. Which expression can be used to find the
percent of change?
Answer:
Find the difference between the two, divide by the years, and should get the percent of change
Step-by-step explanation:
The change in percentage is 69.89%.
Given that, a gym's membership in 2012 was $9,300.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
The current membership is $2,800.
We know that, the percentage change = (New value - Original value)/Original value × 100
Now, the percentage change = (9300-2800)/9300 × 100
= 6500/9300 × 100
= 0.6989 × 100
= 69.89%
Therefore, the change in percentage is 69.89%.

Gavin and Ethan are training for a race. Last week, Gavin ran 7 kilometers, and Ethan ran twice as far as Gavin. What is the total distance that Gavin and Ethan ran last week? Express your answer in meters.
If Ethan ran twice as far as Gavin then he ran 14 kilometers. 7*2=14. And then you add 7 to 14 which gives you 21. so they ran a total of 21 kilometers
The total distance that Gavin and Ethan ran last week is 21000 meters.
Given that, Gavin and Ethan are training for a race.
What is total?A total is a whole or complete amount, and "to total" is to add numbers or to destroy something. In math, you total numbers by adding them: the result is the total.
Last week, Gavin ran 7 kilometers, and Ethan ran twice as far as Gavin.
Number of kilometers Ethan ran =2×7
= 14 kilometers
= 14×1000
= 14,000 meters
Now, 7 kilometers = 7000 meters
Total =14000+7000
= 21000 meters
Therefore, the total distance that Gavin and Ethan ran last week is 21000 meters.

What is a unitary method?A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.
Given, A motorist drives at a constant rate of 60 kph and his destination is 240 kilometers away from his starting point.
We know, Distance = time×speed.
time = distance/speed.
time = 240/60.
time = 4 hours.
speed×time = distance.
60t = 240.
