I have 2 questions to ask 1 is divide 180 degrees in a ratio of 4,5 and 9the other one is divide 42 in a ratio 1 2 and

Answers

Answer 1

Answer:
Here's how to do dividing in a certain ratio:

-- You want to divide up the whole thing in the ratio of
4 parts, 5 parts, and 9 parts.

-- How many parts all together ? (4 + 5 + 9) = 18 parts all together.

-- The whole thing is 180, and that's 18 total parts.
So each part is (180/18) = 10 degrees.

4 parts = (4 x 10) = 40
5 parts = (5 x 10) = 50
9 parts = (9 x 10) = 90.

Check: (40 + 50 + 90) = 180 . yay!

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

For the second one, I think there are some words missing.

What is 6 kg 650g to the nearest 1/2kg

Answers

Given:
6kg 650g
1/2 kg

1/2 kg is equal to 500 grams

1 kg = 1000 grams

We need to convert these figures from kg to g.

6 kg * 1000g/kg = 6*1000g = 6,000 g

6,000 g + 650 g = 6,650 g

6,650 g ÷ 500 g = 13.3 round off to 13

13 * 500 g = 6,500

6 kg 650 g is nearest to 6,500 g.

A shoe box is 10 inches long and 6 inches wide. It is 3 inches tall. Sage is wrapping the shoe box and determined that she needs 20% more than the total surface area in gift wrap to cover the box and account for overlap. How many square inches of gift wrap does she need?

Answers

Answer: $360\ in^2$

Step-by-step explanation:

For this exercise you need to use the folllowing formula for calculate the Surface area of a Rectangular prism:

$SA = 2wl + 2lh + 2hw$

Where "l" is the length, "w" is the width and "h" is the height of the prism.

In this case you can identify that:

$l=10\ in\n\nw=6\ in\n\nh=3\ in$

Therefore, substituting values, you get that the surface area of the shoe box is:

$SA = 2(6\ in)(10\ in) + 2(10\ in)(3\ in) + 2(10\ in)(6\ in)\n\nSA=300\ in^2$

The 20% of this surface area is:

$(300\ in^2)(0.20)=60\ in^2$

Since she needs 20% more than the total surface area in gift wrap to cover the box and account for overlap, you get that total amount of square inches of gift wrap that she needs is:

$Total=300\ in^2+60\ in^2=360\ in^2$
