The length of a rectangle is 15 less than three times the width. The perimeter of the rectangle is 178 centimeters. What is the length of the rectangle?

Answers

Answer 1

Answer:

40.5in

Step-by-step explanation:

Given data

Let the  width be x

L= 3x-15

Perimeter= 178cm

We know that

P=2L+2W

substitute

178= 2(3x-15)+2x

open bracket

178=6x-30+2x

collect like terms

178=8x-30

178-30= 8x

148= 8x

divide both sides by 8

x= 148/8

x=18.5 in

but L= 3x-15

L= 3*18.5-15

L=55.5-15

L=40.5 in

Hence the length is 40.5in

A cup can hold 125ml of water when full how much cups would it take to fill a jug that can hold 3/4 L

Answers

Answer:

6 cups

Step-by-step explanation:

Given that:

Volume of water held in cup when full = 125ml

Number of cups it will take to fill a jug which holds 3/4 L

Converting mL to L:

1000 mL = 1 L

Volume of water in cup when full = 125 / 1000 = 0.125 L

Jug which holds 3/4 L = 0.75 capacity

Hence, number of cups it'll take :

0.75 / 0.125

= 6

It will take 6 cups of 125mL to fill 3/4 L

George has just purchased a small rectangular fish tank that holds 837 milliliters of water. The tank has a width of 6.2 cm and a
height of 9 cm.
What is the length of the fish tank?

Answers

Answer:

Step-by-step explanation:

Answer:

15 cm

Step-by-step explanation:

Area = Length ⋅ Width ⋅ Height

let's set:

Area: 837

Length: X

Width: 6.2 cm

Height: 9cm

837 = X ⋅ 6.2 ⋅ 9

First multiply 6.2 and 9 to get 55.8

Next divide 837 by 55.8 and you get 15

therefore, the length (x) is equal to 15

Step-by-step explanation:

Step 1: Define Systems

6x - 5y = 15

x = y + 3

Step 2: Solve for y

Substitution

Substitute in x:                                                                                                  6(y + 3) - 5y = 15Distribute 6:                                                                                                    6y + 18 - 5y = 15Combine like terms:                                                                                        y + 18 = 15[Subtraction Property of Equality] Subtract 18 on both sides:                     y = -3

Step 3: Solve for x

Define original equation:                                                                               x = y + 3Substitute in y:                                                                                                   x = -3 + 3Add:                                                                                                                   x = 0

the graph of g(x) = x³ -9x² + 3x -1 is translated up 5 units to produce the graph of the function h(x). what would be the new equation of h(x)​

Answers

Answer:

h(x) = x^3 - 9x^2 + 3x + 4

Step-by-step explanation:

To write the new equation, we have to understand what the translation is about

What it means is that we are going to add the 5 units to the total value of the equation

we have this as:

h(x) = x^3-9x^2 + 3x-1 + 5

h(x) = x^3 - 9x^2 + 3x + 4
