Answer:

<h2>y=5</h2>

Step-by-step explanation:

75+3x+(4x+10)

ok look at the triangle 2 sides are congruent means 2 angles are congruent

that means that 75 and 3x are congruent

75=3x

divide by 3 both sides

x=25

75+75=150

30=4y+10

y=5

If A rectangular prism with a volume of 2 cubic units is filled with cubes with side lengths of 1/4. How many 1/4 unit cubes doe
PSYCHO15rus [73]

Answer:

It'll take 128 cubes to fill the prism.

Step-by-step explanation:

In order to solve this question we first need to find the volume of the cubes. The volume of a cube is given by the following formula:

volume = length³

So the cubes have the following volume:

volume = (1/4)³ = 1/64

Since we want to know how many of these cubes are needed to fill the prism, we need to divide prism's volume by the volume of the smaller cubes. We have:

number of cubes = (volume of prism)/(volume of cubes)

number of cubes = 2/(1/64)

number of cubes = 2*(64/1)

number of cubes = 128

It'll take 128 cubes to fill the prism.

Express the area A of a right triangle as a function of the height h if the base of the triangle is twice it's height
borishaifa [10]
Base = 2 x height (b = 2h)
Area = 1/2 x base x height = 1/2 x 2h x h = h x h = h^2

Please solve this, will rate 5 stars and mark as STAR!​
Nina [5.8K]

Answer:

\boxed{5 \cdot \sqrt{2}  \cdot \sqrt[6]{5} }

Step-by-step explanation:

\sqrt[3]{250} \cdot \sqrt{\sqrt[3]{10} }

\sqrt{\sqrt[3]{10} } \implies (10^\frac{1}{3} )^\frac{1}{2} =10^\frac{1}{6} =\sqrt[6]{10}

\therefore \sqrt{\sqrt[3]{10} }=\sqrt[6]{10}

\text{Solving }\sqrt[3]{250} \cdot \sqrt{\sqrt[3]{10} }

250=2 \cdot 5^3

\sqrt[3]{250}=\sqrt[3]{2\cdot 5^3}=5  \sqrt[3]{2}

Once

\sqrt[6]{2}  \cdot \sqrt[6]{5} = \sqrt[6]{10}

We have

5  \sqrt[3]{2} \cdot \sqrt[6]{2}  \cdot \sqrt[6]{5}

We can proceed considering the common base of exponentials

\sqrt[3]{2}  \cdot \sqrt[6]{2}  =  2^{\frac{1}{3}} \cdot  2^{\frac{1}{6} }  = 2^{\frac{3}{6} } = 2^{\frac{1}{2} }=\sqrt{2}

Therefore,

5  \sqrt[3]{2} \cdot \sqrt[6]{2}  \cdot \sqrt[6]{5} = 5 \cdot \sqrt{2}  \cdot \sqrt[6]{5}

Need help with what the answer to this question is
levacccp [35]
The answer is C
C has units of Markers / Markers on the left and Money over an unknown which represents money.

None of the others (D) is incorrect, because we've already chosen C.

A is not because.you have the wrong amount of money divided by the larger number of makers. 

B does not work because the right is markers divided by money. The left had side will have money divided by markers. It won't work. The safest way to  these questions up is to keep the knows on the left and put the unknown on the left with the number it is associated with.
Let's see why the others don't work.
