Answer: 3173 mm² (Answer C)
Area of the bottom triangle = 1/2 x base x height
Area of the bottom triangle = 1/2 x 19 x 23 = 218.5mm²
Area of the top triangle = area of the bottom triangle
Area of the top triangle = 218.5mm²
Area of the 3 side rectangles = (23 x 38) + (19 x 38) + (30 x 38)
Area of the 3 side rectangles = 2736 mm²
Total Surface area = 218.5 + 218.5 + 2736 = 3173 mm²

Given:
The number of 100.
To find:
The given number as an exponential expression with 10 as the base.
Solution:
We have,
Given number = 100
It can be written as
![[\because a^m\cdot a^n=a^{m+n}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20a%5Em%5Ccdot%20a%5En%3Da%5E%7Bm%2Bn%7D%5D)
Here, base is 10 and exponent is 2.
Therefore, the given number can be written as 
.
For this you are adding two fractions together. You always want to make sure they are both improper or normal fractions and that they have a common denominator. To find a common denominator, you look at the denominators and look for a number (The smaller the better) that both can be multiplied by some number to get to. In this case, the common denominator is 10. To make the denominators the same you multiply by one so the value doesn't change. This is done by multiplying the numerator and denominator by the same number that results in the denominator becoming the common denominator.
2 1/2 = 5/2 × 5/5 = 25/10
2/5 × 2/2 = 4/10
When adding, the denominator remains the same and the numerators are added!
25 + 4 = 29
So the answer is 29/10 or 2 9/10 when converted back into a mixed number.
Hope this helped!
Answer:
7. 25 and 8. 18. I think it is. I hoped that is was right.
Step-by-step explanation:
150/6=25. 90/5=18.
The answer is a. Because at approximately 17 weeks the two lines meet.
