Answer:
25. [tex]27a^{3}b^{2}[/tex]
26. [tex]3\pi x^{3}y[/tex]
Step-by-step explanation:
For 25:
[tex]A = \frac{a+b}{2} h[/tex] (area of a trapezoid)
[tex]A=\frac{11a^{2}b+7a^{2}b}{2} *3ab[/tex] (substitute terms)
[tex]= \frac{18a^{2}b}{2}*3ab[/tex] (collect like terms)
[tex]= 9a^{2}b*3ab[/tex] (reduce the fraction by crossing out 2)
[tex]= 27a^{3}b^{2}[/tex] (calculate)
For 26:
[tex]A=\pi r^{2}[/tex] (equation of area of a circle)
[tex]A=\pi (3x^{3} y)^{2}[/tex] (enter the radius)
[tex]= 3\pi x^{3} y[/tex] (communtative property to reorder the terms)

Answer:
a) This expression is simply the average of both of their hours for a full year.
b) Honestly, I'm not sure, but mathematically, its [tex]\frac{Beth's -hours}{Arjun's-hours}[/tex], so the hours cancel out and you get the ratio of their yearly hours? Idek
c) a/12 would be the number of hours Arjun worked per month since there are 12 months in a year.
d) This one is a difference between Arjun's hourly wage to Beth's hourly wage. So, it represents how much more Arjun would have made (Arjun's hourly wage) in comparison to Beth, or vice versa (depending on who worked more hours).
c) Similar to a), this is an average of their yearly income.

Step-by-step explanation:
There are 9 movies ranked on the summer's "must see movie list." What is the probability that you guess the summer's top two must see movies if you randomly guess?
Answers
Answer:
1/36 = 0.0278 = 2.78% probability that you guess the summer's top two must see movies if you randomly guess
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this question, the order in which the movies are chosen is not important, which means that we use the combinations formula to solve this question.
Combinations formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
Desired outcomes:
Top two movies, so only one outcome, which means that [tex]D = 1[/tex]
Total outcomes:
Two movies from a set of 1. So
[tex]T = C_{9,2} = \frac{9!}{2!(9-2)!} = 36[/tex]
Probability:
[tex]p = \frac{D}{T} = \frac{1}{36} = 0.0278[/tex]
1/36 = 0.0278 = 2.78% probability that you guess the summer's top two must see movies if you randomly guess
Answer:
1.39%
Step-by-step explanation:
This is a permutation problem because order matters.
There are 9! ways to rank the summer's must-see movies.
There are (9−2)!=7! ways to choose two movies as the top two must-see movies.
P = 7!/9! = 1/72 = 0.0139
To express our answer as a percent, we multiply by 100:
0.0139 x 100 = 1.39%

A skateboard costs $240. The sales tax on the skateboard is $12. What the percent of the sales tax?
Answers
Answer:
5%
Step-by-step explanation:
12 divided by 240 is 0.05, which is a PERCENTAGE FRACTION (as I like to call it).
This means that you can easily make this into a percentage.
Example Percentage Fractions:
A whole number, like 1 for example, is 100% or more.
The number 1 is 100%, and 2 is 200% and 4.25 is 425%
But since 12 divided by 240, in this problem, is 0.05, it is 5%.
Example are:
0.08 is 8%
0.02 is 2%
0.43 is 43%
0.79 is 79%
It's pretty simple.

A 6-foot person standing 20 feet from a streetlight casts a 5-foot shadow. Two similar triangles are formed. One triangle is formed by the person and the shadow that the person casts. A second triangle is formed by the streetlight and the ground from the base of the streetlight to the end of the shadow.
The street light is __ times taller than the person.
Answers
Answer:
2 times taller
Step-by-step explanation:
[tex]\frac{6}{10} = \frac{x}{20}[/tex]
120=12x
x = 12ft
x=height of street light
the street light is 12 feet tall so the street light is 12 times taller than the person
