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?
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.

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]
or
R = 2524 quarts/s
So, the rate of flow of water is 2524 quarts/s.

What is the value of x?
x+13=9
Enter your answer in the box in simplest form
plz i will give 15
Answer:
x = -4
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define equation
x + 13 = 9
Step 2: Solve for x
Subtract 13 on both sides: x = -4Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: -4 + 13 = 9Add: 9 = 9Here we see that 9 does indeed equal 9.
∴ x = -4 is a solution of the equation.
Answer:
x=-4
Step-by-step explanation:
So when solving a one-step algebraic equation you need to remember what you do to one side you have to do to the other side. In the problem x + 13 = 9 you need to subtract 13 from both sides to isolate x. So your problem should look like x = 9 - 13. Now all you have to do is solve 9 - 13 which is -4. So x = -4.

Find the measure of each numbered angle
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
