the height of the snow was 84 inches in the beginning of the week. it melts at a rate of 0.15 inches per hour. how many hours wo

lakkis [162]

Answer:

It takes 147 hours for the snow to reach 62 inches.

Step-by-step explanation:

Given:

Height of the snow at the beginning = 84 inches

Rate at which the snow melts = f 0.15 inches per hour

To Find:

The time taken for the snow to reach 62 inches = ?

Solution:

Let the time taken to reach 62 inches be x

Then according to the question,

Total height of the snow - (rate of melting)(x) = 62 inches

On substituting the values,

84 - (0.15)(x) = 62

84 - 0.15x = 62

- 0.15x = 62 - 84

- 0.15x = -22

0.15x = 22

x = \frac{22}{0.15}

x= 146.6

x = 147

Math question 2! Thanks if you help

Greeley [361]

Answer: 15.6 m

Step-by-step explanation:

Two legs of right angle in right triangle given are 12m and 10m.

For the third side use Pythagoras theorem:

C^2= a^2+b^2

C=√[(12^2)+(10^2)]

C=√[144+100]

C=√[244]= 15.6 m

Write a program that accepts a whole number as Input multiplies that number by 12 the outputs the product

frez [133]

Answer:

Step-by-step explanation:

programs can be written in multiply languages. for this solution I'll be writing in C++.

#include<iostream> // this is called the preprocessor definition

using namespace std;

int main() //the main function

{

int num, product; //declaration of the variables

cout << "enter the whole number";

cin >> num;

product = num * 12;

cout << product; // displaying the final results

return 0;

What is the solution of the system?

Serjik [45]

Answer:

(-13,-4)

Step-by-step explanation:

4x-8y=-20

9x+113=y

Substitute in y for 9x+113

4x-8y=-20

Substitute

4x-8(9x+113)=-20

Simplify

4x-72x-904=-20

Simplify

-68x-904=-20

Additive Prop. of Equality

-68x-904+904=-20+904

Simplify

-68x=884

Isolate the variable(x)

-68x -68x

Simplify

x=-13

Solve for y

9x+113=y

9(-13)+113=y

-117+113=y

-4=y

Check

4x-8y=-20

4(-13)-8(-4)=-20

-52+32=-20

-20=-20

9x+113=y

9(-13)+113=-4

-117+113=-4

-4=-4

Akira receives a prize at a science fair for having the most informative project. Her trophy is in the shape of a square pyramid

PolarNik [594]

Akira needs 45 square inches of gold foil to cover the chair free including the bottom

Step-by-step explanation:

Total surface = surface area of the base square + area of 4 triangles

Step 1: The surface area of the base square

surface area of the base = surface area of the square =

where s is the side length

The the surface area of the base = = 9 square inches

Step 2: The surface area of the side triangles

The area of the triangle =

On substituting the values,

The area of the triangle =

The area of the triangle = 9 square inches

Now the area of 4 triangles = 4 x 9 = 36 square inches

Thus the total surface area = 9 + 36 = 45 square inches
