Help Fast Please!!!!!!!!! How can you tell if three positive numbers form a Pythagorean triple?

Fiesta28 [93]

Answer/Step-by-step explanation:

Square all three numbers. If the largest number squared is equal to the sum of the squares of the other two, then the numbers form a Pythagorean triple.

<u><em>or</em></u>

Since a Pythagorean triple is three positive integers a, b, and c such that (a^2)+(b^2)=(c^2), first take the sum of the squares of the two legs and make an estimate. For example, 3, 4, and 5 is a Pythagorean triple since 9+16=25

The cost for the raw materials of marble countertops, can be represented by the function , where is the area of the countertops.

Lady_Fox [76]

Answer:

$m(c(a)) = 4.8875a$

Step-by-step explanation:

The missing parameters are:

$c(a) = 4.25a$ --- Cost of marble countertops

$m(c) = 1.15c$ --- Cost of retail markup

Required

The cost of marked up price

This implies that we calculate m(c(a))

We have:

$c(a) = 4.25a$

$m(c) = 1.15c$

$m(c) = 1.15c$ can be written as:

$m(c(a)) = 1.15*c(a)$

Substitute: $c(a) = 4.25a$

$m(c(a)) = 1.15*4.25a$

$m(c(a)) = 4.8875a$

Hence, the cost of marked up price is: $m(c(a)) = 4.8875a$

PLS HELP WILL MARK BRAINLIST IF ANSWER IS CORRECT !! :) FILL IN THE BLANKS

andrew-mc [135]

Answer:

Part 1) The volume of the storage body is 576 cubic feet

Part 2) To find out how many boxes can she fit in the storage body, divide the volume of the storage body by the volume of each box

Part 3) Sheila can fit 64 boxes into the truck

Step-by-step explanation:

step 1

Find the volume of the storage body

we know that

The volume of the of the storage body is equal to the volume of two rectangular prism

The volume of a rectangular prism is equal to

$V=LWH$

First rectangular prism (top)

$V=(15)(6)(8-6)=180\ ft^3$

Second rectangular prism (bottom)

$V=(15-4)(6)(6)=396\ ft^3$

The volume of the storage body is

$V=180+396=576\ ft^3$

step 2

we know that

To find out how many boxes can she fit in the storage body, divide the volume of the storage body by the volume of each box

step 3

substitute the given values

$\frac{576}{9}= 64\ boxes$

therefore

Sheila can fit 64 boxes into the truck
