to find the area of a trapezoid dylan uses the formula A=1/2 (B1+B2)h the bases have lengths of 3.6 cm and 12 1/3 cm. the height
Artemon [7]

Answer:

It is irrational because it can not be represented as a fraction of two integers

Step-by-step explanation:

Given

B_1 = 3.6

B_2 = 12\frac{1}{3}

H = \sqrt[3]5

Required

Why is the area irrational?

First, we need to calculate the area

Area = \frac{1}{2}(B_1 + B_2) * H

Area = \frac{1}{2}(3.6 + 12\frac{1}{3}) * \sqrt[3]5

Area = \frac{1}{2}(3.6 + \frac{37}{3}) * 17100

Area = \frac{1}{2}(\frac{10.8+37}{3}) * 1.710

Area = \frac{1}{2}(\frac{47.8}{3}) * 1.7100

Area = \frac{47.8}{6} * 1.7100

Area = \frac{47.8* 1.7100}{6}

Area = \frac{81.738}{6}

Area = 13.623

<em>It is irrational because it can not be represented as a fraction of two integers</em>

Martina chose a random sample of 10 bags of candy from two different Brands, A and B. All bags in the sample are the same size.
Alborosie
I found the dot plots that accompanies this problem.

Based on the plots, the <span>statement that gives is a valid comparison of the number of candies in the bags of the two Brands is:

</span><span>B. The number of candies in the bags from Brand B is greater and less consistent than the number of candies in the bags from Brand A.

Dots in Brand B are scattered and whereas dots in Brand A are not and they are more concentrated between 52 to 55 range. </span>

Is each fraction in simples form? Write yes or no 2/4
shusha [124]
Hey there! :D

When a fraction is still divisible by a number, then it is not in it's simplest form. 

For example, 3/6. 

I know for a fact that 6/3=2 <== 3 is also divisible by itself. 

3/6 (3/3=1) (6/6=1) 

1/2 <== simplest form. 

Try the same with 2/4. 

4 is divisible by 2. 

4/2= 2

2/2=1

1/2 is the simplest form. 

I hope this helps!

1.05)^n = 350000/270000 = 1.296296

n =  log 1.296296 / log 1.05 = 5.3 years answer
