Answer:

D 4/121

C 14/55

Step-by-step explanation:

The total number of tiles in mathematics is 11

P(a) = number of a's/ total = 2/11

We replace the tile

so there are 11 tiles and the are mathematics

P(a) = number of a's/ total = 2/11

P(a, replace then a) = 2/11 *2/11 = 4/121

P(vowel) = vowel/total = 4/11

We keep the vowel so there are only 10 tiles

3 vowels and 7 consonants

P( consonants) = consonant/total = 7/10

P(vowel, no replace, consonant) = 4/11*7/10 = 14/55

Rewrite the following expression.

faust18 [17]

We have been given the expression

$x^{\frac{9}{7}}$

We have the exponent rule

$x^{\frac{a}{b}}= x^{a^{(\frac{1}{b})}}$

Using this rule, we have

$x^{\frac{9}{7}}= x^{9^{(\frac{1}{7})}}$

Now, using the fact that $x^{\frac{1}{n}}=\sqrt[n]{x}$ , we get

$x^{\frac{9}{7}}= \sqrt[7]{x^9}\\
\\
x^{\frac{9}{7}}=\sqrt[7]{x^7\times x^2}\\
\\
x^{\frac{9}{7}}=x\sqrt[7]{x^2}$

D is the correct option.

Which shows the correct solution to the inequality 7/10> 1 5/8+p

Bogdan [553]

Answer: $\begin{bmatrix}\mathrm{Solution:}\:&\:p$

Step-by-step explanation:

$\frac{7}{10}>1\frac{5}{8}+p$

$\frac{7}{10}>\frac{13}{8}+p$

$\frac{13}{8}+p$

$\frac{13}{8}+p-\frac{13}{8}$

$p$

City code says you need to have a total of at least 54 toilet stalls, but each bathroom can only have 6 stalls. How many bathroo

Lady bird [3.3K]

City code says you need to have a total of at least 54 toilet stalls, but each bathroom can only have 6 stalls.

So, Let the number of bathrooms to be built be = x

Number of toilet stalls needed = 54

Number of stalls each bathroom can have = 6

So, the number of bathrooms to be built are =

$6(x)=54$

$x=\frac{54}{6}$

$x=9$

Hence, one must build 9 bathrooms with 6 stalls each.
