16) A company has found that its expenditure rate per day (in hundreds of dollars) on a certain type of job is given by E'(x) =

erastova [34]

Answer:

$61

Step-by-step explanation:

Given

Number of days, x = 5

Expenditure per day, E'(x) = 10x + 11

Required

Determine the expenditure per day (E'(x))

From the question, we have that

$E'(x) = 10x + 11$

Substitute 5 for x

$E'(5) = 10 * 5 + 11$

$E'(5) = 50 + 11$

$E'(5) = 61$

Hence, the expenditure for 5 days is $61

The mean of a particular set of 7 numbers is 4. Six of the numbers in the set are known: 1,2,2,5,7,and 8.

Setler [38]

$\dfrac{1+2+2+5+7+8+x}{7}=4\\
\dfrac{25+x}{7}=4\\
25+x=28\\
\boxed{x=3}

I need help plz help

amid [387]

We know

$\boxed{\sf cos\Theta=\dfrac{b}{h}}$

$\\ \sf\longmapsto cos22=\dfrac{x}{47}$

$\\ \sf\longmapsto 0.9=\dfrac{x}{47}$

$\\ \sf\longmapsto x=47(0.9)$

$\\ \sf\longmapsto x=42.3$

The value of 4 in 3,492 is how many times the value of 4 in 704?

Norma-Jean [14]

100, because in 3,492, it is in the hundreds place. In 704, it is in the one's place. 100/1 is 100. So 100 times greater.
