The answer should be the 1st one.

Just use the quadratic formula and plug in the necessary numbers when requested and work from there.

A video game designer is modeling a tower that is 320 ft high and 260ft wide. She creates a model so that the similarity ratio o

H = Tower Height = 320
W = Tower Width = 260
h = Model Height
w = Model Width

h = (1/500) * H = (1/500) * 320 = .64 feet
w = (1/500) * W = (1/500) * 260 = .52 feet

Now, we need to convert these measurements to inches.

There are 12 inches per foot.

Let x = height in inches and y = width in inches

The ratio below compares feet to inches

x / h = 12 in / 1 ft
y / w = 12 in / 1 ft

Plug in h and w, cross multiply, and solve for x and y, respectively.

x / .64 = 12 / 1
1 * x = .64 * 12
x = 7.68 in

y / .52 = 12 in / 1 ft
1 * y = .52 * 12
y = 6.24 in

Data:
Apples = 28
Oranges = 20
Pears = 12

<span>What is the ratio of apples to the total pieces of fruit?
Solving:
</span>\frac{apples}{apples+oranges+pears} =  \frac{28}{28+20+12} =  \frac{28}{60} \frac{\div4}{\div4} \to\:\boxed{\boxed{ratio = \frac{7}{15}}}\end{array}}\qquad\quad\checkmark<span>
