If you would like to know what percent of 100 is 30, you can calculate this using the following steps:

x% of 100 is 30
x% * 100 = 30
x/100 * 100 = 30
x = 30%

The correct result would be a. 30%.

We set up a proportion: 30/100= ?/100

Because we have the same denominator, the two numerators must be equivalent.

Therefore, ?= 30.

The correct answer is a. 30%

If Δ ABC = Δ DEF, which one of these is a pair of corresponding parts?<br> CB and ED<br> AC and DF
Radda [10]

Answer:

AC and DF

Step-by-step explanation:

Corresponding sides as well as corresponding angles have a pair of same angles or sides that are in the same place in two different shapes that are similar.

Find attached the diagram used for solving the question

Since Δ ABC = Δ DEF

∠B corresponds to ∠E

∠A corresponds to ∠D

∠C corresponds to ∠F

As a result of the above:

Line AB corresponds to line DE

Line AC corresponds to line DF

Line BC corresponds to line EF

Therefore, if Δ ABC = Δ DEF, one of the pair of corresponding parts would be AC and DF.

SVETLANKA909090 [29]

She must win the next 8 consecutive games to get 80% and after that loose the next 12 games to get to 50%.

<h3>How to find the probability of winning?</h3>

She has won 8 out of 12 days. Thus, percentage of winning is;

P(winning) = 8/12 * 100%

P(Winning) = 75%

To arrive at 80% winning, it means that the number of extra consecutive games she must win is;

(8 + x)/(12 + x) = 80/100

10(8 + x) = 8(12 + x)

80 + 10x = 96 + 8x

2x = 16

x = 8

Thus, she must win the next 8 consecutive games to get 80%.

For her to get to 50% after that, it means that;

(16 - x)/(20 - x) = 50/100

(16 - x)/(20 - x) = 1/2

2(16 - x) = 20 - x

32 - 2x = 20 - x

x = 12
