The following two right triangles are similar.If side PQ = 42, side LM = 28, and side QR = 24, what is the length of side MN?

Phantasy [73]

Answer:

a. 16

Step-by-step explanation:

Find the scale:

42 ÷ 28 = 1.5

Use this scale for QR to find MN:

24 ÷ 1.5 = 16

a museum employee surveys a random sample of 350 visitors to the museum. Of those visitors, 266 stopped at the gift shop. Based

Naddika [18.5K]

1748 people are expected to stop at the gift shop out of 2300.

Step-by-step explanation:

Given,

Number of random sampled people = 350

Number of people who stopped at shop = 266

Percentage = $\frac{People\ stopped}{Total\ people}*100$

Percentage = $\frac{266}{350}*100=76\%$

Therefore,

76% people would stop at the gift stop.

Number of people = 2300

Expected number = 76% of total

Expected number = $\frac{76}{100}*2300$

Expected number = 1748

1748 people are expected to stop at the gift shop out of 2300.

Will a 9/32 inch diameter pin fit into a reamed hole with a diameter of 0.278 inch? (Do not round off your answer and express it

ollegr [7]

Answer:

9/32 inch diameter pin will not fit into a reamed hole with a diameter of 0.278 inch

Step-by-step explanation:

Diameter of reamed hole = 0.278 inch

Radius of reamed hole = $\frac{0.278}{2} =0.139$

Surface area of reamed hole = $\pi r^2$

Surface area of reamed hole = $3.14 \times (0.139)^2$

Surface area of reamed hole = 0.06066794

Diameter of pin = $\frac{9}{32}$

Radius of pin = $\frac{9}{64}$

Surface area of pin = $\pi r^2 = 3.14 \times ( \frac{9}{64})^2=0.0620$

Since the surface area of pin is more than the surface area of hole .

So, a 9/32 inch diameter pin will not fit into a reamed hole with a diameter of 0.278 inch

I think its easier to work out part (c) first:-

People who liked anything except burger = 3/8 + 1/4 + 1/5 = 33/40

So the fraction who liked burgers = 7/40.

7/40 of the total liked burgers so total people surveyed = (40/7) * 126 = 720

ANswer to c is 720.

a) Number who liked chicken and laksa = (3/8 + 1/4) * 720 = 450 Answer

b) Number who liked pasta = 1/5 * 720 = 144

Therefore 144-126 = 18 more people liked pasta than burger , Answer.
