The distance between two cities on a map is 4 1/2 inches. The actual distance between the two cities is 24 miles.
What is the scale used on the map?
If the scale on a different map of the same area is 1/4 inch = 1 mile, how many inches separate the same two cities?

Helper
Jan 13, 2020
the scale is 4.5in/24mi
since 1 mile = 63360 in, that means the scale is
4.5 : 24*63360 = 4.5 : 1520640 = 1:337920

Maybe now you can figure the scale on the 2nd map.

if 1 mile = 1/4 inch, then 24 miles = 24 times that in inches.

PsyDAG
Jan 13, 2020
huh. I guess you can't follow the logic? If 1/4 inch = 1 mile then the scale is
1/4 in : 63360 inin = 1/4 : 63360
now just simplify that so it is 1 : ____

At Breakfast Break, 2 eggs and 1 sausage patty cost $2.23 and 3 eggs with 2 sausage patties cost $3.76. Assuming that these amounts only pay for the eggs and sausage, how much does one sausage patty cost?

Answers

I am thinking one sausage patty cost $4.25

Cost of one sausage patty is $0.83.

What is an equation?

An equation is a combination of different variables, in which two mathematical expressions are equal to each other.

Given that,

Cost of 2 eggs and 1 sausage patty = $2.23,

Cost of 3 eggs and 2 sausage patties = $3.76.

Write above expression in equation form,

2 eggs + 1 patty = 2.23             (1)

3 eggs + 2 patties = 3.76         (2)

To find the cost of patty, multiply equation (1) with 3 and equation (2) with 2,

6 eggs + 3 patties = 6.69         (3)

6 eggs + 4 patties = 7.52          (4)

By solving equation (3) and (4)

1 patty = 0.83

The cost of 1 sausage patty is $0.83.

A trapezoid has a height of 10 feet, and base measurements of 20 feet and 8 feet. What is the area?

The answer must be in square feet

Answers

Answer:Therefore, the area of the trapezoid

Step-by-step explanation
To find the area of a trapezoid, you can use the formula: A = 1/2 * (b1 + b2) * h, where b1 is the length of the longer base, b2 is the length of the base, and h is the trapezoid's height.

In this case, the longer base (b1) is 20 feet, the shorter base (b2) is 8 feet, and the height (h) is . We obtain the following result as soon as we insert these values into the formula:
A = 1/2 * (20 + 8) * 10
A = 1/2 * 28 * 10
A = 140 square
