Find the unknown side length x write your answer in simplest radical form

Sauron [17]

Answer:

(B) $4\sqrt{37}$

Step-by-step explanation:

First, we determine the height of the triangle which we label as y.

Using Pythagoras Theorem.

$25^2=7^2+y^2\\y^2=25^2-7^2\\y^2=576\\y=\sqrt{576}\\y=24$

In the smaller right triangle with hypotenuse, x

Base = 7-3 =4 Units

Height, y= 24 Units

Therefore, applying Pythagoras Theorem.:

$x^2=24^2+4^2\\x^2=592\\x=\sqrt{592}\\ x=4\sqrt{37}$

The members of the city cultural center have decided to put on a play once a night for a week. Their auditorium holds 500 peopl

konstantin123 [22]

Answer: In first question, Number of student's ticket(s) = 400

And number of adult's ticket(d) = 100

In second question, The goal of $3050 fell by $710

Step-by-step explanation:

1. Since, Here d represents the number of adult tickets and s represents the number of student tickets.

And, all 500 seats are filled for a performance.

Therefore, s + d = 500 ------(1)

Also, the price of one adult's ticket = $8.50

The price of one student's ticket= $5.50

And, their is a revenue of $3050 by selling the tickets.

Thus, 8.50 d + 5.50 s = 3050 --------(2)

By solving the equation (1) and equation (2),

we get, s = 400, d=100

Thus, Number of student's ticket(s) = 400

And number of adult's ticket(d) = 100

2. According to the question,

s = 2 d ----- (3)

s + d = 360 -----(4)

By solving equation (3) and (4),

We get, s = 240 and d = 120

thus, the total revenue after selling 360 tickets = 8.50 × 120 + 5.50 × 240 = $2340

But, the goal is $3050 ( according to the question)

Thus the total fall = 3050 - 2340 = $710

shusha [124]

Answer:

Option: d is the correct answer.

d. 5 x 26 x 26 x 10 x 10 x 10 x 10 – Allow for more first letters to be used.

Step-by-step explanation:

It is given that:

The rules for license plates in Idaho are 3 letters followed by 4 numbers (example ABC 1234), where the first letter can only be the letters I, D, A, H, or O.

The number of different ways it could be done is:

as for the first place we have just 5 choices. ( as just 5 letters I, D, A, H, or O are to be used )

for the second place we have 26 choices. ( All the 26 alphabets could be used )

and same is for the third place we have 26 choices.

Now for the fourth,fifth,sixth and seventh places we have 10 choices.

Hence, the number of ways it could be done is:

5×26×26×10×10×10.

Also the number of ways the number of license plates can be increased is by not taking any restriction for the first place.

i.e. Allow for more first letters to be used.

Hence, the answer is:

Option: d

d. 5 x 26 x 26 x 10 x 10 x 10 x 10 – Allow for more first letters to be used.
