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>

Write the equation of the line shown in point slope form (1,2) (3,6)

Kipish [7]

The point-slope form:

$y-y_1=m(x-x_1)\\\\m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points (1, 2) and (3, 6). Substitute:

$m=\dfrac{6-2}{3-1}=\dfrac{4}{2}=2\\\\\boxed{y-2=2(x-1)}$

Can someone just please explain why in PEMDAS for example: 6 + 9 ÷ 3 × 7. Why do you do the division (9/3) before the multiplica

Grace [21]

Because is division is before multiplication you have to do division even though the m is before d.

The manager at Gabriela's Furniture Store is trying to figure out how much to charge for a book shelf that just arrived. The boo

Burka [1]

Answer: The manager sold the book shelf at $235.2

Step-by-step explanation:

Since we have given that

Wholesale price of the book shelf = $147.00

But Gabriela's Furniture Store marks up all furniture by 60%.

So, Mark up value is given by

$\frac{60}{100}\times 147\\\\=\frac{8820}{100}\\\\=\$88.2$

So, the new price that the manager sold the book shelf is given by

$147+88.2\\\\=\$235.2$

Hence, the manager sold the book shelf at $235.2

HELP DUE IN 10 MINS!!

fredd [130]

Answer:

D. No, they are not similar.

Step-by-step explanation:

<u>Check the ratio of the two given sides:</u>

MV/VT = 21/49 = 3/7
LV/VU = 8/28 = 2/7

Ratios are different so the triangles are not similar

Correct choice is D
