Answer 1

Answer:

(1-2) LS = 288cm² TS = 378cm²

(3-4) LS = 1419.2 TS = 1673.5

(5) LS = 543 TS = 606

Step-by-step explanation:

(1-2)

7 1/2 = 7.5

7.5 x 15 = 112.5

9 x 12 ➗ 2 = 54

54 x 2 = 108

9 x 7.5 = 67 .5

(3-4)

3.14 x 81 = 254.3

(5)

9 x 15 = 135 x 2 = 270

15 x 7 = 105 x 2 = 210

9 x 7 = 63

It takes 4.12 gallons of paint to paint a fence.

How much paint is needed for 1/5 of the fence?

[answer] gallons

Answers

4.12 divided by 5 = 0.824

The amount of paint needed for 1/5 of the fence is 0.824 gallons.

What is the unitary method?

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. Unitary method is a technique by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit. It is a method that we use for most of the calculations in math.

We are given that;

Paint= 4.12gallons

Now,

To find the amount of paint needed for 1/5 of the fence, we can use the following proportion:

14.12=1/5x

where x is the unknown amount of paint. To solve for x, we can cross-multiply and get:

x=14.12×1/5

Simplifying, we get:

x=0.824

Therefore, by unitary method the answer will be 0.824 gallons.

A circle has a diameter of 21 meters. What is the circumference of the circle? Use 22/7 for π. (PI)

Answers

≈║∧║······→Hello←······║∧║≈

Your answer should be:

Why...?

Simple.

First, you multiply 21 by 22/7. But to make this easier you have to fix in 'improper fraction.' and make it into an improper fraction. Which will become 3 1/7. Now you multiply 21 and 3 1/7. Which will equal 66. So, 66 is your answer.

What is a circle?

A circle is a two-dimensional figure with a radius and circumference of 2pir.

The area of a circle is πr².

We have,

The circumference of a circle is given by the formula:

C = πd

where C is the circumference and d is the diameter.

Substituting the given values:

C = πd = (22/7) x 21 = 66 meters

Therefore,

The circumference of the circle is 66 meters.

B.

C.

D.
$650.50

Answers

The answer would be A)$679.80
The reason for this is let’s start with the mark up of 10%. Meaning we will add the result of the markup to our first number We would take 1000*.1 which would give us 100.
Add that to the original to give you $1,100.
Then the item was discounted for 40% meaning we take away the result of 1,100*.4 which equals 440. 1100-440=660.
Then taxes are added on to the total so you would do 660*.03 which would give you 19.8
660+19.8 gives you$679.80.
