Answer:

D) a: 4(4) + 1/2(3)(4)

Step-by-step explanation:

1. The floor is split into a square and a triangle, as the two side lengths of the quadrilateral are both 4 feet.

C and D are looking for the area of a rectangle and a triangle. They can not be right.

2. The area of a triangle is found by multiplying the base and the height, which in this case, since it is a right triangle, the two legs. In that situation, said legs are 7 - 4 = 3 feet and 4 feet, while the hypotenuse is 5 ft. B plugs in the equation leg * hypotenuse, which is not correct.

The only answer is A (which is D in the selection).

 $1.64 * 10^0 : 2.0 * 10^2= (1.64:2.0) * 10^0:10^2= 0.82 * 10 ^{0-2} = \\ \\ 0.82 * 10 ^{-2} =0.82 * \frac{1}{10^2} =0.82 * \frac{1}{100} =0.0082= \boxed{ 8.2 * 10^{-3} }$

Help. IM SO LOST ON THIS! ;(

castortr0y [4]

Answer:

1. 4 $\frac{2}{3}$

Step-by-step explanation:

For question 1, you need to know the ratio between the recipe and the amount in question.

So if in the recipe, it says it uses 3/4 cup of diced ham, and the question uses 1 cup of diced ham, you can divide 1 by 3/4 to get 4/3. This is how many times bigger the amount used in the question than the recipe.

Then it asks for how many cups of potatoes, to do this, you look at the recipe and how many potatoes it uses: 3.5 cups

To solve it then, you just do 3.5 x 4/3 to get 4 $\frac{2}{3}$ cups of potatoes

There's your answer.

Select the expression that simplifies to 1 / x^1/8

Troyanec [42]

Answer:

$\left(\displaystyle \sqrt[3]{x^{-\tfrac 35}}\right)^{\tfrac 58}$

Step-by-step explanation:

$\left(\displaystyle \sqrt[3]{x^{-\tfrac 35}}\right)^{\tfrac 58}\\\\\\=\left[ \left(\displaystyle x^{-\tfrac 35} \right)^{\tfrac 13 \right]^{\tfrac 58}\\\\\\=\left( \displaystyle x^{-\tfrac 35}\right)^{\tfrac 5{24}}\\\\\\=x^{ \displaystyle -\tfrac{3}{24} \right}\\\\\\=x^{\displaystyle -\tfrac 18 }\\\\\\=\dfrac 1{x^{\tfrac 18}}$
