Answer:
There are 7,725 square feet of grass on the trapezoidal field
Step-by-step explanation:
Here in this question, we are interested in calculating the square feet of grass present on the trapezoidal field.
What this question is actually asking us is to calculate the area of the trapezoid-shaped grass field.
To calculate this area, what we need to do
simply is to use the formula for the area of a trapezoid.
Mathematically, the area of a trapezoid can be calculated using the formula;
Area of trapezoid = 1/2 * (a + b) * h
where a and b refers to the length of the parallel lengths of the trapezoid and h refers to the height of the trapezoid.
From the question;
a, b = 81ft and 125 ft
h = 75 ft
Substituting these values, we have :
Area = 1/2 * (81 + 125) * 75
Area = 1/2 * 206 * 75 = 83 * 75 = 7,725 ft^2
First we write the variables already defined:
m = the number of magazine subscriptions sold
n = the number of newspaper subscriptions sold
We now write the system of inequations based on the following facts:
"he earns $ 23 for each magazine subscription and $ 54 for each newspaper subscription that he sells. his goal is to make more than $ 642 per week"
23m + 54n> 642
"I have expectations to sell at least 10 subscriptions per week"
m + n> = 10
Answer:
A system of inequalities that models the given situation is:
23m + 54n> 642
m + n> = 10

Kindly check explanation
5 years from now, Johnathan will be (5 + 4) = 9 years
Step-by-step explanation:
Let Belinda's age = x
Jonathan's age =1/3 x
In 12 years, Belinda will be m years old :
Belinda's age now = x
Jonathan's age 5 years from now, if m = 36
Belinda's age in 12 years, Belinda's age = m
x + 12 = 36
x = 36 - 12
x = 24 years
Hence Belinda's age now is 24
Jonathan's age now is (1/3) * 12 = 4 years
Hence, 5 years from now, Johnathan will be (5 + 4) = 9 years
