Two friends get frozen yoghurt. The rate the topping is 4:3. If one of the friends has 4.5 oz of topping in their bowl, which of the following is the amount of yoghurt in their dessert?

Let two number be x and y. Then

Three time a number=3x

Eight times a different number=8y

Sum of the two is 3x+8y

Here are the calculations for the medium and large pizzas:

Medium Pizza:

Diameter: 11 inches

Area: ××= 95.03 square inches

Price: $9

Cost per square inch: = 9.47 cents

Large Pizza:

Diameter: 15 inches

Area: ××= 176.71 square inches

Price: $13

Cost per square inch: = 7.36 cents

Cost Difference

The large pizza costs about 2.11 cents less per square inch than the medium pizza.

C. 17.8 cm.

Explanation

To convert inches to centimeters, we use the conversion factor:

1 inch = 2.54 centimeters.

7 inches×2.54 cm/inch

=17.78 cm

The percent equivalent of a fraction is obtained by multiplying the by frication by 100%.

Convert 5 ¼ into improper faction as follows

So, percent equivalent is:

Since the screen sizes are proportional, we can set up a proportion based on the diagonal lengths of the screens.

Let x be the length of the vehicle on the 50-inch screen. The proportion based on the screen sizes is:

=

Now, solve for x:

x = = ≈14.06

Rounding to the nearest inch, the vehicle will appear about 14 inches long on the 50-inch screen.

The most likely weight of pencil is 25 g, because a pencil is a lighter object which is measured in grams.

Based on the context, a synonym for "salient" is important, as it refers to points that are prominent or significant in the presentation.

A 10% discount on the original price of $950 equals $95 (10% of 950 = 95). Subtracting this discount from the original price, $950 - $95, gives a sale price of $855.

In this case, we are measuring average weight of the babies with time. The weight of the babies will vary with time, meaning when we vary time, the average weight of the babies will be different. Here, time is independent while average weight is dependent variable.

Determine the number of blue and yellow gumballs as follows:

Percent of blue gumballs=100%-(20%+30%+5%+10%) =100%-65%=35%

Number of blue gumballs =35% of 120=0.55*120 = 42 blue gumballs [35%=35/100=0.35]

Number of yellow gumballs=5% of 120=0.05*120 = 6 yellow gumballs [5%=5/100=0.05]

Difference between number of blue and yellow gumballs=42-6= 36 balls

Therefore, there are 36 more blue gumballs than yellow gumballs.
