Answer:
[tex]\%Tip = 13.04\%[/tex]
Step-by-step explanation:
Given
[tex]Tip= \$31.29[/tex]
[tex]Bill = \$208.60[/tex]
Required
Determine the percentage of the tip
First, we calculate the amount paid
[tex]Amount = Tip + Bill[/tex]
[tex]Amount = \$31.29 + \$208.60[/tex]
[tex]Amount = \$239.89[/tex]
The percentage of the tip is then calculated using:
[tex]\%Tip = \frac{Tip}{Amount} * 100\%[/tex]
[tex]\%Tip = \frac{31.29}{239.89} * 100\%[/tex]
[tex]\%Tip = \frac{31.29* 100}{239.89} \%[/tex]
[tex]\%Tip = \frac{3129}{239.89} \%[/tex]
[tex]\%Tip = 13.04\%[/tex]

A sum of two mixed numbers is given.
What is the missing number?
Answer:
16.
Step-by-step explanation:
The whole numbers stay the same so it stays as 2. The way they get 30 for the denominator is by multiplying the fraction 1/3 by 10 and 1/5 by 6. So now we have 10/30 and 6/30. Add them together, 10+6=16
A population of bacteria P is changing at a rate based on the function given below, where t is time in days. The initial population (when t = 0) is 900. dP dt = 2900 1 + 0.25t Write an equation that gives the population at any time t. Then find the population when t = 2 days. (Round your answer to the nearest whole number.)

Answer:
a. 17 b. 51
Step-by-step explanation:
Follow Order of Operations (PEMDAS):
Parentheses, Exponents, Multiplication/Division, Addition/Subtraction
a. 9 + 4² - (4-2) • 4
9 + 4² - (4-2) • 4 –––Start with (4-2) = 2 (parentheses)
9 + 4² - 2 • 4 ––– 4² (exponents)
9 + 16 - 2 • 4 ––– 2 • 4 (multiplication)
9 + 16 - 8 ––– 9 + 16 (addition)
25 - 8 ––– 25 - 8 (subtraction)
17
b. 15 - 4 + 2(7-3) • 5
15 - 4 + 2(7-3) • 5 ––– Start with 2(7-3)
~ Note: this can be done using distributive property (2•7 - 2•3) OR solving the parentheses first and then multiplying 2(4). Both get 8 and same end result.
15 - 4 + 8 • 5 ––– 8 • 5 (multiplication)
15 - 4 + 40 ––– 15 - 4 (subtraction) *Note: Subtraction and addition are interchangeable in the order because you do it left to right*
11 + 40 ––– 11 + 40 (addition)

3. A manufacturing process produces integrated circuit chips. Over the long run, the fraction of bad chips produced by the process is 20%. Thoroughly testing a chip to determine whether it is good or bad is rather expensive, so a cheaper test is used. All good chips will pass the test, but so will 6% of the bad chips. a) (4 points) What is the probability that a randomly chosen chip will pass the test
Answer:
0.812 = 81.2% probability that a randomly chosen chip will pass the test
Step-by-step explanation:
Over the long run, the fraction of bad chips produced by the process is 20%.
So 100 - 20 = 80% are good.
All good chips pass the test, while 6% of the bad chips(20%) also pass.
a) (4 points) What is the probability that a randomly chosen chip will pass the test
[tex]p = 0.8 + 0.06*0.2 = 0.812[/tex]
0.812 = 81.2% probability that a randomly chosen chip will pass the test

Determining Median is super easy!
1. Order the numbers, in ascending order.
8, 11, 11, 12, 13, 15, 16, 16, 18, 21
2. Cross off one number from both ends until you reach the middle number, whether you're left with one or two.
11, 11, 12, 13, 15, 16, 16, 18
11, 12, 13, 15, 16, 16
12, 13, 15, 16

A sector has an area of 50 ft sq, and a central angle of 45 degrees. Find the radius.
Answer:
Step-by-step explanation:
45° is 1/8 of a circle, so the area of the sector is 1/8 the area of the circle.
Area of circle = 8*50 = 400 sq ft
πr² = 400
r = √(400/π) = 20/√π ≈ 11.3 ft

Solve each single-step equation. Show your work. - 6 b + 2 < 56
Answer:
b > −9
Step-by-step explanation:
−6b+2<56
Step 1: Subtract 2 from both sides.
−6b+2−2<56−2
−6b<54
Step 2: Divide both sides by -6.
−6b −6 < 54 −6
b >−9

Find the coordinates of the circumcenter of the triangle with the given vertices.
A(2, 6), B(8, 6), C(8, 10)
The circumcenter is
9514 1404 393
Answer:
(5, 8)
Step-by-step explanation:
The circumcenter of a right triangle is the midpoint of the hypotenuse.
O = (A +C)/2
O = ((2, 6) +(8, 10))/2 = (2+8, 6+10)/2
O = (5, 8)
The circumcenter is (5, 8).
