Answer:

$\boxed{\boxed{PQ=3.6\ in}}$

Step-by-step explanation:

As it is given as ΔQRP and ΔARC are similar, so the ratio of their corresponding sides will be same.

So,

$\dfrac{RC}{PR}=\dfrac{AC}{PQ}$

It is given as,

RC = 3.3

PR = 1.8

AC = 6.6

PQ = ??

Putting the values,

$\Rightarrow \dfrac{3.3}{1.8}=\dfrac{6.6}{PQ}$

$\Rightarrow PQ=\dfrac{6.6\times 1.8}{3.3}=3.6$

In Ms.Khans class,22 out of 25 students hand in their projects on time. What percent of the class hand in their projects on time

Nikitich [7]

88 % students of the class hand in their projects on time

Solution:

Given that, Ms.Khans class, 22 out of 25 students hand in their projects on time

Total number students = 25

Students hand in their projects on time = 22

To find: percent of the class hand in their projects on time

$\text{ percent of class hand in time } = \frac{\text{Students hand in projects on time}}{\text{total students}} \times 100$

Substituting the values, we get

$\text{ percent of class hand in time } = \frac{22}{25} \times 100\\\\\text{ percent of class hand in time } = 0.88 \times 100\\\\\text{ percent of class hand in time } = 88$

Thus 88 % students of the class hand in their projects on time

Donna takes classes at both Westside community college and pinewood community college. at westside , class fees are $98 per cred

Alex777 [14]

Answer:

Expression for the combined total dollar amount she paid for her class fees is (2185 - 17 w)

Step-by-step explanation:

Let Donna is taking w credit hours at Westside.

Total combined credit hours at two schools = 19 hours

So, the number of credit hours at Pinewood = 19 - w

The per hour fees credit of Westside community college = $98

So, the total fees paid for w hours = w x Fees per hour

= w ( $98) = $(98w)

⇒The fees Donna pays at Westside community college = $ (98 w)

The per hour fees credit of Pinewood community college = $115

So, the total fees paid for (19 -w) hours = (19 -w) x Fees per hour

= (19 -w) ( $115) = $(2185 - 115 w)

⇒The fees Donna pays at Pinewood community college =$(2185 - 115 w)

Hence, the total fees paid by Donna

= Fees at Westside + Fees at Pinewood

= $ (98 w) + $(2185 - 115 w)

= $(2185 - 17 w)

Hence, expression for the combined total dollar amount she paid for her class fees is $(2185 - 17 w)
