Answer:

Step-by-step explanation:
Let x represent the missing number
[tex] 8\frac{11}{15} = 7\frac{x}{15} [/tex]
Convert both fractions to improper fractions
[tex] \frac{131}{15} = \frac{105 + x}{15} [/tex]
Cross multiply
[tex] 15(105 + x) = 15(131) [/tex]
[tex] 1,575 + 15x = 1,965 [/tex]
Subtract both sides by 1,575
[tex] 15x = 1,965 - 1,575 [/tex]
[tex] 15x = 390 [/tex]
Divide both sides by 15
[tex] x = \frac{390}{15} [/tex]
x = 26

Recall: adjacent angles supplementary
Therefore,
65x + 115° = 180°
Subtract 115° from each side
65x + 115° - 115° = 180° - 115°
65x = 65
Divide both sides by 65
65x/65 = 65/65

Gary went to dinner with his friends. The total bill comes to $135.00 before tax. He wants to leave a 15% tip before tax. He also must pay an 8% tax on the bill. How much does Gary spend in total?
No links or I will report!
Answers
Answer:
Gary spends a total of $166.05
Step-by-step explanation:
15% tip: would be 15% of 135, so 0.15 times 135, which would be $20.25 for the tip before tax
8% tax: would be 8% of 135, so 0.08 times 135, which would be $10.8
Then we add $20.25+$10.8+$135= $166.05

Step-by-step explanation:
We can use sohcahtoa to solve this. First, we know that this triangle is a right triangle, as well as one angle and the opposite side to that angle. We are trying to find the hypotenuse.
Therefore, as sin takes opposite and hypotenuse into account, we can use that to get that sin(41°) = 2.5/x . Multiply both sides by x and divide both sides by sin(41°) to get x = 2.5/sin(41°) =3.8

Step-by-step explanation:
Volume of the pyramid = 1/3 * base area * height
Base area = 12 * 12
Base area - 144 sq. cm
Height = 6cm
Volume of the pyramid = 144 * 6/3
Volume of the pyramid = 144 * 2

Answer=

B) What is the probability that daily production is more than 45.7 liters? Use technology (not tables) to get your probability.
Answer=
(Round your answer to 4 decimal places.)
Answers
Answer:
A) 0.0359
B) 0.0829
Step-by-step explanation:
A) Using normalcdf on your calculator, or using something online, you can plug (-1000, 23.4, 36, 7) to represent the lower bound, upper bound, mean, and standard deviation respectively. The probability that daily production is less than 23.4 liters is 0.0359
B) Similarly, we can plug (45.7, 1000, 36, 7) in as the upper bound is infinity, and the lower bound if 45.7. Our answer is then 0.0829

Answers
Answer:
Mean mass of 20 rugby player = 55
Step-by-step explanation:
Given:
Mass of 6 rugby players = 540 kg
Mean mass of 14 ballet dancer = 40 kg
Find:
Mean mass of 20 rugby player
Computation:
Total mass of ballet dancer = 14 x 40
Total mass of ballet dancer = 560 kg
Total mean mass of 20 rugby player = [540 + 560] / [6 + 14]
Mean mass of 20 rugby player = 1100 / 20
Mean mass of 20 rugby player = 55

Answer:
1/5 = 20% = 0.201/4 = 25% = 0.251/2 = 50% = 0.52/3 = 66.6...% = 0.6...Step-by-step explanation:
The symbol % is interchangeable with /100. That is 25% = 25/100. One percent is one hundredth, so the decimal equivalent can be found by writing the percentage number in the hundredths place of a decimal number.
25% = 25/100 = 0.25 = 25 hundredths
The fractions can be converted to percentages by any of ...
multiply by 100%: 1/5 × 100% = (100/5)% = 20%
multiply by a value that makes the denominator 100: 1/5 × 20/20 = 20/100
divide the numerator by the denominator to get the decimal, then convert
1/5 = 0.20 = 20%
__
Additional comment
You will notice that multiplying by 100% is the same as moving the decimal point right 2 places and adding a % symbol. Similarly, dividing by 100% will convert a percentage back to a decimal. It has the effect of removing the % symbol and shifting the decimal point left 2 places.

Answer:
The possible solutions are -4 and -12
Step-by-step explanation:
(C+8)^2=16
Take the square root of each side
sqrt((C+8)^2)=sqrt(16)
C+8 = ±4
C+8 = 4 C+8 = -4
Subtract 8 from each side
C+8-8 = 4-8 C+8-8 = -4-8
C = -4 C = -12
The possible solutions are -4 and -12
