When completing an online shopping transaction, a typical shopper takes 5 seconds to select each product and another 60 seconds
natulia [17]

4 products are being purchased.

Step-by-step explanation:

Given,

Time taken to select each product = 5 seconds

Time taken to complete check out process = 60 seconds

Total time taken for a transaction = 80 seconds

Let,

x be the number of products purchased.

Time taken for each product*Number of product + Time for check out process = total process

5x+60=80\\5x=80-60\\5x=20

Dividing both sides by 5

\frac{5x}{5}=\frac{20}{5}\\x=4

4 products are being purchased.

Given a triangle with: a =<br> 150, A = 75°, and C = 30°<br> Using the law of sines gives: c = 0
koban [17]

Answer:

c = 77.6

Step-by-step explanation:

You may have entered the measure of a side as the measure of an angle.

\dfrac{\sin A}{a} = \dfrac{\sin C}{c}

\dfrac{\sin 75^\circ}{150} = \dfrac{\sin 30^\circ}{c}

c\sin 75^\circ = 150 \sin 30^\circ

c = \dfrac{150 \sin 30^\circ}{\sin 75^\circ}

c = 77.6

You are correct. Good job!

what is the scale factor of triangle UVW to triangle XYZ where uvw has side Lengths 3,4,2, and XYZ has lengths 14,28,21
alekssr [168]

Answer: 7

Step-by-step explanation:

Given:  Triangle UVW map to triangle XYZ where Triangle UVWhas side Lengths 3,4,2, and triangle XYZ has lengths 14,28,21.

We know that the scale factor between two similar figures is the the ratio of the corresponding side of image to the original figure.

Let k be the scale factor.

Then,

k=\frac{21}{3}=\frac{14}{2}=\frac{28}{4}=7\\\\\Rightarrow\ k=7

Hence, the scale factor = 7
