Answer:

x=22\ yd

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is proportional

so

\frac{x}{14}=\frac{77}{49}

solve for x

x=\frac{77}{49}(14)

x=22\ yd

katrin2010 [14]

Answer:

Here

Step-by-step explanation:

We move all terms to the left:

7+9x-(6x-2)=0

We get rid of parentheses

9x-6x+2+7=0

We add all the numbers together, and all the variables

3x+9=0

We move all terms containing x to the left, all other terms to the right

3x=-9

x=-9/3

x=-3

SCORPION-xisa [38]

Answer:

2.62

Step-by-step explanation:

log_{b} \frac{b^{2}x^{\frac{5}{2} }}{\sqrt{y}}

First, write the square root as exponent.

log_{b} \frac{b^{2}x^{\frac{5}{2} }}{y^{\frac{1}{2}}}

Move the denominator to the numerator and negate the exponent.

log_{b}(b^{2}x^{\frac{5}{2}}y^{-\frac{1}{2}})

Use log product property.

log_{b}(b^{2}) + log_{b}(x^{\frac{5}{2}}) + log_{b}(y^{-\frac{1}{2}})

Use log exponent property.

2 log_{b}(b) + {\frac{5}{2}}log_{b}(x) - {\frac{1}{2}}log_{b}(y)

Substitute values.

2(1) + \frac{5}{2}(0.36) - \frac{1}{2}(0.56) \\2.62

You have a rectangular prism on your hands. The formula for the volume of a rectangular prism is

(B/2) • l

Where B is the area of the base, and l is the length.

If you notice, you do NOT have the height of the triangle. However, you know that it is an equilateral triangle. So, you may split the triangle into two. Once you do, you can see that it is a right triangle. It’s hypotenuse is 3. If you know your triangles, you will realize that this is a 30 60 90 triangle. Therefore, the height will be 1.5 * sqrt(3)

So, to get B...

3 * 1.5sqrt(3)
4.5sqrt(3)
(Divide by 2)
2.25sqrt(3)
O
(9sqrt(3))/4
Multiply by the length of the prism, 6

This is your final answer in fraction form

— 2^rt(3)
