Kelly's Cafe has regular coffee and decaffeinated coffee. This morning, the cafe served 20 coffees in all, 30% of which were regular. How many regular coffees did the cafe serve?

Answers

Answer:

the cafe served 6 regular coffees

Step-by-step explanation:

to get your answer you can multiply the percentage times the amount served in total

Total regular coffees served = 6.

What is percentage?

A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word per cent means per 100. It is represented by the symbol “%”.

Given,

Total coffees served = 20

No. of regular coffees = 30% of 20

= 30/100 × 20

No. of regular coffees = 6

Hence, Kelly's café served 6 regular coffees.

Water flows through a pipe at a rate of 8600 cubic meters per hour. Express this rate of flow in quarts per second. Round your answer to the nearest whole number.

Answers

Answer:

R = 2524 quarts/s

Step-by-step explanation:

Water flows through a pipe at a rate of 8600 cubic meters per hour.

We know that,

1 m³ = 1056.69 quarts

1 hour = 3600 s

Rate of flow of water = 8600 cubic meters per hour

[tex]R=8600\ \dfrac{m^3}{h}\\\\=8600\times \dfrac{1056.69\ \text{quarts}}{3600\ s}\\\\=2524.311\ \text{quarts/s}[/tex]

R = 2524 quarts/s

So, the rate of flow of water is 2524 quarts/s.

Find the measure of each numbered angle

Answers

Answer:

m∠1 = 54° m∠2 = 63° m∠3 = 117°

Step-by-step explanation:

We know that 117 + m∠2 = 180°, which when calculated is equal to 63. Now, we know that 63 + 63 + m∠1 = 180°. This comes out to be 54°. Finally, we know that m∠3 has to equal 117° because they are same side interior angles.

The measure of m<1, m<2 and m<3 are 54, 63 and 63 degrees respectively

The sum of angle in a straight line is 180 degrees, hence:

m<2 + 117 = 180

m<2 = 180 - 117

m<2 = 63 degrees

For the diagram, m<2 - m<3 = 63 degrees (alternate angle.)

Also, the sum of interior angle of the triangle is 180 degrees, hence:

m<2 + m<2 + m<1 = 180

63 + 63 + m<1 = 180

126 + m<1 = 180

m<1 = 180 -126

m<1 = 54degrees

Hence the measure of m<1, m<2 and m<3 are 54, 63 and 63 degrees respectively
