If a recipe requires 400 grams of potatoes for four people, how many kilograms would be required for 12 people?
Tasya [4]

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:

To find the amount that it accelerated, you need to find the change in the mph.   First you would subtract 70 and 10 to find that number.  That tells you the total amount of change.  Then to figure out how much it would be per second you divided that number by the total number of seconds (12).

Please explain in detail how you solved.​
Alex17521 [72]

Step-by-step explanation:

Since this is a right triangle and we are given an angle measure that measure 45, the other angle measure also measure 45.

So this means we are dealing with a 45-45-90 triangle.

A 45-45-90 triangle legs are equal to each other and the hypotenuse measures sqr root of 2 times more than the legs.

The hypotenuse measure 2 times sqr root of 14 so divide by sqr root of 2 to find x and y.

\frac{2 \sqrt{14} }{1}  \times   \frac{1}{ \sqrt{2 } }  =  \frac{ \sqrt{56} }{ \sqrt{2} }  =  \sqrt{28}  = 2 \sqrt{7}

Since x and y are equal, they both measure

2 \sqrt{7}
