$\frac{-18}{-3}$ (divide 3 from numerator and denominator) = $\frac{6}{1} = 6$

$\frac{2}{7}$ × $\frac{8}{3}$ = $\frac{16}{21}$

$\frac{3}{8} + \frac{1}{12} = \frac{9}{24} + \frac{2}{24} = \frac{11}{24}$

Rachel earned \$34$34 in 44 hours at her job today. She wants to know how much she could earn (e)(e) tomorrow if she works 1010

kari74 [83]

Answer:

<em>Rachel will earn $85 in 10 hours.</em>

Step-by-step explanation:

Rachel earned $34 in 4 hours at her job today.

Suppose, she will earn $x$ dollar in 10 hours tomorrow.

So, <u>according to ratio of 'dollar' and 'hours'</u>, the equation will be.....

$\frac{34}{4}=\frac{x}{10}$

After cross multiplying, we will get.....

$4x= 34*10\\ \\ 4x= 340\\ \\ x=\frac{340}{4}=85$

Thus, Rachel will earn $85 in 10 hours.

Find the 6th term of a geometric sequence with t1=5 and r = -1/2

Hoochie [10]

In this item, we are to calculated for the 6th term of the geometric sequence given the initial value and the common ratio. This can be calculated through the equation,

An = (A₀)(r)ⁿ ⁻ ¹
where An is the nth term, A₀ is the first term (in this item is referred to as t₀), r is the common ratio, and n is the number of terms.

Substitute the known values to the equation,

An = (5)(-1/2)⁶ ⁻ ¹
An = -5/32

Hence, the answer to this item is the third choice, -5/32.
