Answer:

She typed 32 words in her letter

Step-by-step explanation:

Assume that the letter has x words

∵ She typed x words in her letter

∵ She misspelled 8 words

∵ She misspelled 25% of the words she typed

∴ She misspelled 25% of x

→ That means 8 is equivalent to 25% of x

∴ 25% of x = 8

∴ 25% × x = 8

→ Change 25% to decimal by divide it by 100

∵ 25% = 25 ÷ 100 = 0.25

∴ 0.25 × x = 8

∴ 0.25x = 8

→ Divide both sides by 0.25

∵ \frac{0.25x}{0.25} = \frac{8}{0.25}

∴ x = 32

∵ x represents the number of words that she typed in the letter

∴ She typed 32 words in her letter

vovangra [49]

Answer:

The measure of angle x is 26.1\°

Step-by-step explanation:

we know that

In the right triangle of the figure, the tangent of angle x is equal to divide the opposite side to angle x by the adjacent side to angle x

so

tan(x)=\frac{26}{53}

x=arctan(\frac{26}{53})=26.1\°

7. There are 12 singers auditioning for the school musical. In how many ways can the director choose first a lead singer and the
Finger [1]

Answer: The director can choose first a lead singer and then a stand-in for the lead singer in 132 ways.

Step-by-step explanation:

Given : The total number of singers auditioning for the school musical.= 12

The director wanted choose first a lead singer and then a stand-in for the lead singer.

We use Permutations here because order of selecting the singers matters.

The number of permutations of selecting r things out of n things = ^nP_r=\dfrac{n!}{(n-r)!}

Similarly , the number of ways to select 2 singers in an order from 12 singers

^{12}P_{2}{=\dfrac{12!}{(12-2)!}

=\dfrac{12\times11\times10!}{10!}=132

Hence, the director can choose first a lead singer and then a stand-in for the lead singer in 132 ways.
