Answer:

600 Cheese and 900 Pepperoni

Step-by-step explanation:

Setup the equation with 2c(Cheese) + 2.5p(Pepperoni) = $3450(Total Made).

In addition to the equation c + p = 1500(Number of pizzas sold)

Using the second equation (c + p = 1500) solve for one of the variables.

Lets use :

  1. p = 1500 - c
  2. Plus this equation into the original equation, 2c + 2.5(1500 - c) = 3450
  3. Distribute 2.5, 2c + 3750 - 2.5c = 3450
  4. Combine like terms -0.5c + 3750 = 3450
  5. Solve for c: c = 600
  6. Plus 600 in for c into any equation ( lets use c + p = 1500)
  7. 600 + p = 1500
  8. P = 900

Hot air balloons generally descend at the rate of 200 to 400 ft./min. Six balloons to send 245 ft./min. For four minutes find th
Alenkinab [10]

Answer:

1,715 feets

Step-by-step explanation:

Give the following :

General descent rate of hot air balloon = 200 - 400ft/min

Six balloons descend at a rate of 245 ft/min for four minutes

The total change in altitude for all six balloons :

From speed = distance / time

Speed = 245 ft / min ; time = 7 minutes

Hence distance descended by the six balloons :

245 ft/min × 7 minutes = 1,715 fts

Hence total change in altitude = 1,715 feets

A triangle has an area of 48 square centimeters. The height of the triangle is 6 centimeters. What is the base of the triangle?
andrew11 [14]

Question :-

  • A Triangle has an Area of 48 cm² . The Height of the Triangle is 6 cm . What is the Base of the Triangle ?

Answer :-

  • Base of Triangle is 16 cm .

Explanation :-

As per the provided information in the given question, we have been given that the Area of Triangle is 48 cm² . It's Height is given as 6 cm . And, we have been asked to calculate the Base of Triangle .

For calculating the Base of Triangle , we will use the Formula :-

\bigstar \:  \:  \:  \boxed{ \sf{ \: Area \: _{Triangle} \:  =  \:  \frac{1}{2} \:  \times  \: B \:  \times  \: H \:  }}

Where ,

  • B denotes to the Base .
  • H denotes to the Height .

Therefore , by Substituting the given values in the above Formula :-

\dag \: \: \: \sf { Area \: _{Triangle} \:  =  \:  \dfrac{1}{2} \:  \times  \: Base \:  \times  \: Height }

\longmapsto \: \: \: \sf {48 \: = \: \dfrac {1}{2} \: \times \: Base \: \times \: 6 }

\longmapsto \: \: \: \sf {48 \: \times \: 2 \: = \: 1 \: \times \: Base \: \times \: 6}

\longmapsto \: \: \: \sf {96 \: = \: 1 \: \times \: Base \: \times \: 6}

\longmapsto \: \: \: \sf {96 \: = \: 6 \: \times \: Base }

\longmapsto \: \: \: \sf {Base \: = \: \dfrac {96}{6} }

\longmapsto \: \: \: \textbf {\textsf {Base \: = \: 16 \: cm}}

Hence :-

  • Base of Triangle = 16 cm .
