On saturday, you bowl at mar vista bowl, where renting shoes costs $2 and each game bowled is $3.50. on sunday, you bowl at pinz

ExtremeBDS [4]

Given, at Mar Vista bowl the cost of renting shoes = $2.

The cost for each game bowled = $3.50

There are g games given. So the cost for g games bowled = $ $(3.50)(g)$ = $ $(3.50g)$

The total amount soent at Mar Vista Bowl = $ $(2+3.50g)$

At Pinz, the cost for shoe rental = $5.

The cost for each game bowled = $3.25.

So the cost for g game bowled = $ $(3.25)(g)$ = $ $(3.25g)$

Total amount spent at Pinz = $ $(5+3.25g)$

Given, the amount spent ateach of the places is same.

so we can write the equation as,

$2+3.50g = 5+3.25g$

We will move 3.25 to the left side by subtracting it from both sides. we will get,

$2+3.50g-3.25g = 5+3.25g-3.25g$

$2+0.25g = 5$

Now we will move 2 to the right side by subtracting 2 from both sides. We will get,

$2+0.25g-2 = 5-2$

$0.25g = 3$

Now to get g we will divide 0.25 to both sides. We will get,

$\frac{0.25g}{0.25}= \frac{3}{0.25}$

$g =\frac{3}{0.25}$

$g = 12$

So we have got the required answer.

The number of games bowled = 12.

Andrea made a replica of the Empire State Building. The surface area of the model is 45 ft2. What is the surface area of the act

melamori03 [73]

Answer:

<u>87,120 ft²</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Surface area of the Empire State building replica = 45 square feet

Scale factor = 44

2. What is the surface area of the actual Empire State Building in square feet?

For answering the question, we will make the following calculations:

45 square feet = 9 feet * 5 feet or,

45 square feet = 10 feet * 4.5 feet, or,

45 square feet = 20 feet * 2.25 feet.

Now, let's apply the scale factor to all of these probable lengths of the sides of the surface area of the replica, as follows:

(9 *44) * (5 * 44) = 396 * 220 = 87,120 ft²

(10 * 44) * (4.5 * 44) = 440 * 198 = 87,120 ft²

(20 * 44) * (2.25 * 44) = 880 * 99 = 87,120 ft²

<u>As we proved, no matter what are the lengths of the sides of the surface area of the replica. after applying the scale factor, the result is the same: 87,120 ft²</u>

You have been asked to build a scale model of your school out of toothpicks. imagine your school is 30 feet tall. your scale is

sveticcg [70]

Since your scale is 1ft:1.26cm, a 30-ft tall school would need to have a $30*1.26=37.8$ cm model. Dividing this by how tall each toothpick is, you'll get:

$\frac{37.8}{6.3} =6$

ANSWER: The model would be 6 toothpicks tall.

To find out how many cotton swabs you'll need, we just divide 37.8 by how tall each swab is:

$\frac{37.8}{7.7} =5$

ANSWER: The model would be 5 cotton swabs tall.
