2 x 10^7= 20,000,000
4 x 10^6= 4,000,000
20,000,000 - 4,000,000= 16,000,000.
In SI Notation its 16 x 10^6...
I don't really know it but i tried
Answer:
9
===================================================
Explanation:
The area of the parallelogram is equal to the base times height. The formula to use is A = b*h. The height and base are always perpendicular to one another.
The base is some unknown variable b. Multiply the base by the height 15 to get 15*b which is equal to the area 135
Therefore, 15*b = 135
Divide both sides by 15 and we isolate b
15b = 135
15b/15 = 135/15
b = 9
So the base is 9
Check:
area = base*height = 9*15 = 135
so the answer is confirmed
side note: we never use the value 17 at all. It is likely put in there as a distraction.
Step-by-step explanation:
First, let's figure out how many cups of cheese we need for one dozen people.
There are 12 people in one dozen.
<u>3 cups of cheese </u> = <u>x cups of cheese</u>
6 people 12 people
<u>
</u>
that means we will need 6 cups of cheese for 12 people, or one dozen.
However, we want to make nachos for two dozen people.
6 cups of cheese for one dozen x 2 dozen = 12 cups of cheese
<em>You need 12 cups of cheese to make nachos for two dozen people. </em>
Given:
The diameter of the circle = 14 cm
To find:
The area of the circle.
Solution:
We have,
Diameter of the circle = 14 cm
We know that the radius of the circle is half of its diameter. So,
The area of a circle is:
Substituting 
in the above formula, we get
Therefore, the area of the circle is 154 square cm.
