An observation deck extends 202 feet out above the valley. The deck sits 152 feet above the valley floor. If an object is droppe

OleMash [197]

Answer:

Step-by-step explanation:

Given the height of the object as it drops from the observation deck expressed as;

h= -16t^2+152

To determine the the time it will take the object to be 8 feet above the valley floor, we will substitute h = 8 into the equation and calculate t as shown;

8 = -16t^2+152

subtract 8 from both sides

8-8 = -16t^2+152-8

0 = -16t^2+144

0-144 = -16t^2

-144 = -16t^2

16t^2 = 144

Divide both sides by 16;

16t^2/16 = 144/16

t^2 = 9

t = √9

t = 3seconds

Hence it will take 3 seconds for the object to be 8 feet above the valley floor

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
