Answer:

$67\frac{23}{28}$

Step-by-step explanation:

$36-\left[100\div \:560-32\left(8\div \:4-1\right)\right]\\\\100\div \:560-32\left(8\div \:4-1\right)\\\\=100\div \:560-32\cdot \:1\\\\=\frac{100}{560}-32\cdot \:1\\\\=\frac{100}{560}-32\\\\=-\frac{891}{28}\\\\\\=36-\left(-\frac{891}{28}\right)\\\\36-\left(-\frac{891}{28}\right)\\\\=36+\frac{891}{28}\\\\\frac{36\cdot \:28}{28}+\frac{891}{28}\\\\\frac{36\cdot \:28+891}{28}\\\\=\frac{1899}{28}\\\\\\\frac{1899}{28}(1899\div28)=67\frac{23}{28}$

Julie runs 2 1/2 miles in the morning for 3 days per week, 6 1/2 miles in the morning for 2 days a week, the other days she ride

Makovka662 [10]

2.5*3 = 7.5 She run's 2 1/2 miles, which is equivalent to 2.5 miles, and 3 days per week, so you multiply 2.5 by 3
6.5 *2 = 13 She run's 6.5 miles per day for 2 days, again, because 6 1/2 is equivalent to 6.5 miles. Since she ran for 2 days so you multiply 6.5 by 2
13+7.5 = 20.5 miles
as for the answer, you just add the two numbers you got from Julie running

Which could be the area of the base of a triangular prism?

11Alexandr11 [23.1K]

Option A:

The area of the base of the triangular prism is 6 ft².

Solution:

The base of the triangular prism is triangle.

Base of the triangle is 4 ft.

Height of the triangle is 3 ft.

Area of the base of the prism = Area of the triangle

= $\frac{1}{2} bh$

$$=\frac{1}{2}\times 4 \times 3$

Area of the base of the prism = 6 ft²

The area of the base of the triangular prism is 6 ft².

Hence option A is the correct answer.
