Answer:

x = 21

Step-by-step explanation:

Δ EAB and Δ ECD are similar by the AA postulate , then the ratios of corresponding sides are in proportion, that is

$\frac{AB}{CD}$ = $\frac{EB}{ED}$ , substitute values

$\frac{x}{28}$ = $\frac{27}{27+9}$ = $\frac{27}{36}$ ( cross- multiply )

36x = 756 ( divide both sides by 36 )

x = 21

17 POINTS

notsponge [240]

This problem can be solved with a series of additions and subtractions.

The starting value is 500 and we first subtract 120 because on Monday they withdrew 120 dollars which leaves us with 380 dollars.

Next, we add 50 because on Wednesday they deposited 50 dollars which results in 430.

And, If I am not mistaken, we are done because when Braxton bought their basketball ticket, they used their debt card and did not withdrew from their checking account.

So, the answer is 430 dollars.

H (t) = 2t - 2 g(t) = 4t + 5 Find (h(g(t))

ASHA 777 [7]

Answer:

$h(g(t))=8t+8$

Step-by-step explanation:

We are given the two functions:

$h(t)=2t-2\text{ and } g(t)=4t+5$

And we want to find:

$h(g(t))$

So, by substitution, we acquire:

$h(g(t))=2(4t+5)-2$

Distribute:

$h(g(t))=8t+10-2$

Simplify:

$h(g(t))=8t+8$

A school conducted a survey to find out which games students enjoy watching the most. The table below contains the results of th

uysha [10]

Answer:

The relative frequency of the middle school students who watch soccer the most is 33.3%.

Step-by-step explanation:

We are given the table,

Grade Basketball Baseball Football Soccer Tennis Other Total

Elementary 51 18 26 32 4 6 137

Middle 50 24 44 34 7 18 177

High 42 17 58 36 11 24 188

Total 143 59 128 102 22 48 502

Now, we are required to find the relative frequency of the middle school students who watch soccer.

Since, we know,

Total number of students who watch soccer = 102

Number of middle school students who watch soccer = 34

Thus, the relative frequency of the middle school students = $\frac{34}{102}$ = 0.333 i.e. 33.3%

Hence, the relative frequency of the middle school students who watch soccer the most is 33.3%.
