You need to cross a canal and want to determine the distance across the opposite side. Since you're able to take measurements on

MariettaO [177]

Answer:

36.7 ft

Step-by-step explanation:

Measurements for the sides of the canal is given as: 40 ft. and 16 ft.

You solve the above question using Pythagoras Theorem

The distance across the canal is calculated as:

√(40² - 16²)

= √(1344)

= 36.66060556 ft

Approximately = 36.7 ft

Therefore, the distance x across the canal = 36.7 ft

What is the circumference of circle p ? Express in terms of pie

SVETLANKA909090 [29]

The circumference of a circle is calculated using the following equation:

$C= \pi d$

Where d is equal to the diameter (the length of a straight line from one side of the circle to the other side).

We know that the diameter of the circle given (also known as AB) is equal to 20 cm.

We can then plug this into the equation and solve for the circumference:

$C= \pi (20)$

Since the question asks for the answer to be in terms of $\pi$ , this is as far as we need to go. So the circumference of the circle is: $20 \pi$ or D.

The Pizza Barn sells one customer 3 large pepperoni pizzas and 2 orders of breadsticks for $30. They sell another customer 4 lar

pashok25 [27]

Answer:

Pizzas: $8, Breadsticks: $3

Step-by-step explanation:

1. Write an equation.

Let the variables p = price of pizzas, and b = price of breadsticks

The equation: 3p + 2b = $30 for the first customer. The equation: 4p + 3b = $41 for the other customer.

2. Use the Elimination Method.

(4p+3b=41) x3 = 12p+9b=123

- (3p+2b=30) x4 = 12p+8b = 120

------------------------------------------------

8b = 3

Pizzas: $8

Breadsticks: $3

Tess has 2 and 1/2 cups of fruit. How many 3/4 cup servings can she make

avanturin [10]

Turn 2 1/2 into an improper fraction by multiplying 2 by 2, then adding 1 to that number and using 2 as the new denominator. You get 5/2. Then make it the same denominator as the serving size by multiplying it by 2, or 2/1. You get 10/4. After that, see how many times 3 goes into 10. It’s 3, with 1 remaining. Therefore, he can make 3 1/4 servings, or 3, if you need an exact answer.
