2 answers:

8 0

The percentage of people at the scathing ring that are Youth is 65%. You would have to add 13 + 7, to get 20. Then you do 100 percent divided by 20 to get 5. Finally, you would do 5 times 13 to reach 65%.

Right triangle ABC is similar to triangle XYZ. If the length of side AB is 20.8 units, the length of side BC is 36.4 units, and

trasher [3.6K]

Answer:

XY is 4 units.

Step-by-step explanation:

We are given the following in the question:

Right triangle ABC is similar to triangle XYZ.

AB = 20.8 units

BC = 36.4 units

YZ = 7 units

We have to find the length of side XY.

Since the given triangles are similar, they have the following property:

The ratio of corresponding sides of similar triangles are equal.

We can write,

$\displaystyle\frac{AB}{XY}=\frac{BC}{YZ}=\frac{AC}{XZ}$

Putting the given values, we have,

$\displaystyle\frac{AB}{XY}=\frac{BC}{YZ}\\\\\frac{20.8}{XY}=\frac{36.4}{7}\\\\XY = \frac{20.8\times 7}{36.4} =4 \text{ units}$

Thus, the length of XY is 4 units.

Answer:

whatpower7(49) = 2

Step-by-step explanation:

given data

WhatPower7(49)

to find out

Evaluate the expressions WhatPower7(49)

solution

as we know that whatpower mean exponent of equation so we get by given equation

we know whatpower7(49) = 2

because

we know that 7 × 7 = 49

so that 7² = 49

so that the exponent is here 2 for 7 that become 49

so correct answer is 2
