Answers

Answer 1
Answer:

Answer:

B. 360 in²

Step-by-step explanation:

Rectangle 1

length = 12 in

breadth = 12 in

Surface area = length × breadth

⇒Surface area = 12 × 12

⇒Surface area = 144 inch²

Rectangle 3 (behind)

length = 12 in

breadth = 13 in

Surface area = length × breadth

⇒Surface area = 12 × 13

⇒Surface area = 156 inch²

Rectangle 2

length = 12 in

breadth = 5 in

Surface area = length × breadth

⇒Surface area = 12 × 5

⇒Surface area = 60 inch²

Adding the 3 areas we get

144+156+60 = 360 in²

∴ 360 in² of paint is needed to cover all the rectangular faces of the prism.

Answer 2
Answer:

To solve this problem, one must find the surface area of the rectangles. This is the total area of each rectangle added together. The formula for the area of the rectangle is w*l=A

Rectangle one: 13*12 = 156 in^2

Rectangle two: 5*12 = 60 in^2

Rectangle three: 12*12 = 144 in^2

156 + 60 + 144 = 360 in^2

This means total to paint the rectangle sides of the prism, we need 360 in^2 of paint.

Why 1 hundred 4 tens and 14 tens name the same amount.

Answers

First you need to translate these words mathematically as follows:

1 hundred = 100,

1 ten = 10,

2 tens = 2*10 = 20,

3 tens = 3 * 10 = 30,

4 tens = 4 * 10 = 40,

.

.

10 tens = 10 * 10 = 100

We can express 1 hundred 4 tens and 14 tens as follows:

1 hundred 4 tens = 1 hundred + 4 tens = 100 + 40 = 140 --- (1)

14 tens = 14 * 10 = 140 --- (2)

As (1) = (2), therefore, we can say that 1 hundred 4 tens and 14 tens yield the same amount (which is 140).

Because 1 hundred contains 10 tens. So if you are saying 1 hundred and 4 tens it is the same as you would say 10 tens and 4 tens. And if you add them together 10 tens plus 4 tens it will be 14 tens together.

Answers

Manuel will be paying 22 months,because when you subtract $629.00-$57.00=$572.00,then you divide $572.00÷$26.00=22.This could help you.:-)

Julian jogs 2 kilometers east, 4 kilometers north, and then 7 kilometers west. How far is Julian from his starting position, to the nearest tenth of a kilometer?

Answers

Answer:

6.4 kilometer

==============================

Step-by-step explanation:

See the attached figure.

Let Julian starts from point O (0,0)

Julian jogs 2 kilometers east ⇒ arrived to point A (2,0)

4 kilometers north ⇒ arrived to point B (2,4)

and then 7 kilometers west ⇒ arrived to point C (-5,4)

How far is Julian from his starting position?

So, it is required to find the distance OC

From the graph OC = √((-5)^2+(4)^2)=√(25+16)  =√(41) =6.403

So, the distance from his starting position ≈ 6.4 km (to the nearest tenth of a kilometer)
