Answer:
No, she will go $3.15 above 40.
Step-by-step explanation:
1. Since the tip is 15%, you can either multiply 37.52 by 1.15 or 0.15. In the route of multiplying by 0.15, you need to add it to 37.52. I will multiply by 1.15 to make it easier.
2. 37.52x1.15 = 43.148 or about $43.15 (rounded).

A total of 544 tickets were sold for the school play. They were either adult tickets or student tickets. The number of student tickets sold was three times the number of adult tickets sold. How many adult tickets were sold?
Answer:
x=136
Step-by-step explanation:
So lets say x is the number of pencils so, the number of erasers = 544-x
The equation is then 3x = 544-x & x=136
Answer: 136 adult tickets
Step-by-step explanation: If you have 136 adult tickets then you have to multiply that by three in order to get the child tickets. 136 x 3 = 408 and 408 + 136 = 54
Talon Middle School received 219 prize packs. The school gave away f packs during school fundraisers. There were 42 packs passed out during pep rallies throughout the year. At the end of the year, the school had 54 prize packs left. How many packs were passed out during the fundraiser?
Answer:
123
Step-by-step explanation:
219 - 42 = 177 left
177 - f = 54
f = 177 - 54
f = 123 packs were passed out during the fundraiser
123
Step-by-step explanation:
219-42=177
177-54=123 or (f)
Check your work:
219-42=177
177-123=54
Therefore f=123 or 123 packs were passed out during the fundraiser.

16a +1 = 11(a - 4)
Answer:
Exactly One Solution.
Step-by-step explanation:
16a +1 = 11(a - 4)

Given Event A, Event B, and Event C. Event A and Event B are mutually exclusive. Event A and Event C are not mutually exclusive.
P(A) = 0.15
P(B) = 0.35
P(C) = 0.55
What is the probability of the complement of Event B?
0.85
0.35
0.65
0.45
Answer:
0.35
Step-by-step explanation:
The probability of the complement of Event B is equal to 0.65. so option C is correct.
What is the probability?Probability refers to a possibility that deals with the occurrence of random events.
Given;
Event A and Event B are mutually exclusive.
We have given data
P(A) = 0.15
P(B) = 0.35
P(C) = 0.55
We need to find the he probability of the complement of Event B.
The formula for the compliment of the event
P( B⁻ ) = 1 - P( B)
Use the given value in the above formula we have,
= 1 - 0.35
= 0.65
The probability of the complement of Event B is equal to 0.65. so option C is correct.

Which triangle results from a reflection across the line x = 1?
Answer:
d
Step-by-step explanation:
What is the positive solution to the equation 0 = –x2 + 2x + 1? Quadratic formula: x = StartFraction negative b plus or minus StartRoot b squared minus 4 a c EndRoot Over 2 a EndFraction –2 + StartRoot 2 EndRoot 2 – StartRoot 2 EndRoot 1 + StartRoot 2 EndRoot –1 + StartRoot 2 EndRoot
Answer:
See attached for a "Neat" quadratic formula.
a = -1
b = 2
c = 1
x = [-2 +- sqr root( 4 -4*-1*1)] / -2
x = [-2 +- sqr root( 4 -4*-1*1)] / -2
x = [-2 +- sqr root(8)] / -2
x1 = (-2 +2.8284271247) / -2
x1 = .8284271247 / -2
x1 = -0.41421
x2 = (-2 -2.8284271247) / -2
x2 = ( -4.8284271247) / -2
x2 = 2.4142135624
So the equation has the positive solution of
2.4142135624

Complete the following sentence about the rate of change in the tiger population. Round your answer to two decimal places
two decimal places.
The tiger population loses 3/5 of its size every ______ decade.
Answer:
0.33 decades
Step-by-step explanation:
The tiger population loses 3/5 of its size every 0.333 decades.
What is an Exponential Function?An exponential function is what can be represented by the equation
y = aˣ
The number of tigers N(t) has been modeled by the equation
[tex]\rm N(t) = 710 * (\dfrac{8}{125})^t[/tex]
The tiger population loses 3/5th of its size in how much decade has to be found.
if it loses 3/5, the remaining will be 3/5 of the size so,
[tex]\rm \dfrac{2}{5} * 710 = 710 * (\dfrac{8}{125})^t\\\\\\dfrac{2}{5} = (\dfrac{8}{125})^t\\[/tex]
Taking log on both the sides
ln 2 - ln 5 = t( ln 8-ln 125)
t= 0.333
Therefore, the tiger population loses 3/5 of its size every 0.333 decades.

Your savings account pays 2.5% interest per year. How much interest does the account pay per month.
Answer:
0.21%
Step-by-step explanation:
2.5/12=0.208 or 0.21
Based on the interest that your savings account pays per year, the interest paid per month is 0.21%.
How much interest is paid per month?The interest paid per month can be found by dividing the yearly interest by the 12 months of the year.
Therefore, solving gives:
= Annual interest / 12 months
= 2.5% / 12
= 0.21%
In conclusion, this is 0.21%.
