Answer:

1.2 kg

Step-by-step explanation:

We need 400 grams of potatoes for 4 people. That means each person will require 400 / 4 = 100 grams.

Now, we have 12 people, so the total number of grams needed will be:

(100 g/person) * (12 people) = 1200 grams

However, we want the answer in kilograms. There are 1000 grams in a kilogram, so divide 1200 by 1000:

1200 / 1000 = 1.2 kg

The answer is 1.2 kg.

Answer:

1200g or 1.2 kg

Step-by-step explanation:

We know that you need 400 grams of potatoes for 4 people to make a recipe and we want to find out how many for 12 people so

<u>Method 1</u>

First of all we would need to work out the amount needed for 1 person so,

400g = 4 people

? g = 1 person

4 ÷ 1 = 4

400 ÷ 4 = 100

So 100g is needed for one person using that information

1 person = 100g

12 people = ? g

1 × 12 = 12

100 × 12 = 1200 g

<u>Method 2</u>

We can see that we need 400g for 4 people and we want to find out the amount for 12 people so

400g = 4 people

?g = 12 people

12 ÷ 4 = 3

400 × 3 = 1200g

So you would 1200g or 1.2 kg of potatoes to make this recipe for 12 people

What is 26 divided by 130

Elden [556K]

$26:130=\frac{26}{130}=\frac{26:13}{130:13}=\frac{2}{10}=\boxed{0.2}=\frac{2:2}{10:2}=\boxed{\frac{1}{5}}$

PLEASE HELP!!!

rosijanka [135]

Answer:

Area of the other polygon = 4 in.²

Step-by-step explanation:

Area of the bigger polygon : Area of the smaller polygon = square of the side length of the bigger polygon : square of the corresponding side length of the smaller polygon

Let "x" represent the area of the smaller polygon

Thus, we have:

100/x = 20²/4²

100/x = 400/16

100/x = 25

Cross multiply

25x = 100

Divide both sides by 25

25x/25 = 100/25

x = 4

Area of the other polygon = 4 in.²

B. A 50A by 35ft residential

MariettaO [177]

Answer:

1.13 food per square feet

Step-by-step explanation:

Given

Dimension: 50ft by 35ft

Servings = 1975

Required

Determine the amount per servings

First, we calculate the area.

$Area = 50ft * 35ft$

$Area = 1750ft^2$

Next, we calculate the amount per square foot.

This is:

$Rate = \frac{Serivings}{Area}$

This gives;

$Rate = \frac{1975}{1750}$

$Rate = 1.13$

The isosceles triangles below are similar.

ohaa [14]

Answer: a) 2:1. b) 3. c) Perimeter of ΔEFG=36 Perimeter of ΔHIJ=18. d) 2:1

Step-by-step explanation:

a) Find the ratio of GF and JI. 16:8. Simplify by dividing both by 8 to get 2:1.

b) Set up this equation: 6/16=x/8. Cross-multiply. 6*8=48. Divide by 16. 48/16=3.

c) First find the length of one half of GF by dividing 16 by 2. 16/2=8. Set up the Pythagorean theorem. 8^2+6^2=c^2. Square 8 and 6. 64+36=c^2. Add 64 and 36. 100=c^2. Find the square root of 100. c=10.

EF and EG both measure 10 since they are shown to be congruent. 10+10+16=36.

Next find the length of one half of JI by dividing 8 by 2. 8/2=4. Set up the Pythagorean theorem. Since we know x=3, it will be 4^2+3^2=c^2. Square both 4 and 3. 16+9=c^2. Add 16 and 9. 25=c^2. Find the square root of 25. c=5.

HJ and HI both measure 5 since they are congruent. 5+5+8=18.

d) Find the ratio of the perimeters of ΔEFG and ΔHIJ. 36:18. Simplify by dividing both by 6 to get 6:3. Simplify further by dividing both by 3 to get 2:1.
