Answer:
A 1/5^2
Step-by-step explanation:
5^3 x 5^-5
We know that a^b* a^c = a^(b+c)
5^3 x 5^-5 = 5^(3-5) = 5^-2
We also know that a^-b = 1/ a^b
5^-2 = 1/5^2

The perimeter of a rectangle is 16 inches. The equation that represents the perimeter of the rectangle is , where l represents the length of the rectangle and w represents the width of the rectangle. Which value is possible for the length of the rectangle?
7 in.
8 in.
9 in.
10 in.
Answer:
7 in
Step-by-step explanation:
Process of elimination. It can’t be 9 or 10, because 9+9=18 and 10+10=20 (they're more than 16). 8+8=16 exactly, but there’s no room in 16 for the width. Therefore, it’s 7 because 7+7=14

Alternate Interior Angles
Step-by-step explanation:
They are alternate interior angles. The reason this works is because 4 is opposite to 3, meaning that 4 is equivalent to the value of (180-Angle3)
Meanwhile 6 is equivalent to (180-Angle5). Angle 5 is the same value is Angle 4.

There are four sixth graders and seven seventh graders in Elsa's chess club. Two members of the club will be chosen at random to attend a tournament with several other chess clubs. Elsa is using simulation to determine the experimental probability of randomly selecting two sixth graders. So, she places four red discs (to represent the sixth graders) and seven blue discs (to represent the seventh graders) in a bag. She randomly selects one disc from the bag, records the color, keeps the disc out, selects another disc and records it, and then returns both discs to the bag. Elsa does this twenty-five times. Her results are shown in the table below.
b, b b, r b, r b, b r, b

b. 120
c. 144
d. 108
Answer:
a. 135 is the correct answer
Step-by-step explanation:
Want to find out what the total degrees is of the octagon.
Octagon = 1080
Divide 1080 by 8
135 degrees per angle
Answer:
Option A is correct
Step-by-step explanation:
Hint :
Sum of angles in Regular Octagon = 1080°.
Simplify :
[tex] {z}^{o} = \frac{1080}{8} [/tex][tex]∴z = 135[/tex]
Hope it is helpful....the difference of two numbers is 13/24. if 11/12 of the reciprocal of one number is equal to 5/9 of the reciprocal of the other, what are the 2 numbers?
Answer:
The two numbers are 11/8 and 5/6
Step-by-step explanation:
Let the unknown numbers be x and y
Given that the difference of two numbers is 13/24
x - y = 13/24
and that 11/12 of the reciprocal of one number is equal to 5/9 of the reciprocal of the other
11/12 * 1/x = 5/9 * 1/y
11/12x = 5/9y
cross multiply
12x * 5 = 11* 9y
60x = 99y
x = 99y/60
= 33y/20
substitute into x - y = 13/24
33y/20 - y = 13/24
13y/20 = 13/24
24y = 20
y = 20/24
= 5/6
x = 33y/20
= 33 *5/20*6
= 11/8

Write the equation in standard form. Then factor the left side of the equation.
2x2 + 7x = 15
A. (2x – 5)(x + 3) = 0
B. (2x + 3)(x + 5) = 0
C. (2x – 3)(x + 5) = 0
D. (2x + 5)(x – 3) = 0
Answer:
C. (2x – 3)(x + 5) = 0
Step-by-step explanation:
The equation in standard form should be 2x^2 + 7x - 15 = 0
Factored the expression is (2x - 3)(x + 5).
In order to find the factored portion, you must look for factors of the front number (2) to use in the front of the parenthesis and factors of the last number (-15) to go in the end.
When we use the ones that we have above, it distributes to the overall end result.
(2x - 3)(x + 5)
2x^2 - 3x + 10x - 15
2x^2 + 7x - 15

Answer:

The values will be equal in 10 years.
Step-by-step explanation:

There are two ways to do this problem. I'll do it the simplest way -- which will benefit you most if you are about to take a physics class.
Follow these observations.
The difference of speed of these two cars is 70 - 65 = 5 mphThe distance travelled by the first car before the second one starts is 65 miles in 1 hour. That comes about because Tom goes 65 miles before Michelle even starts. She starts exactly 1 hour after Tom and he has gone 65 miles in that time.She is going faster, but he is still moving. That's what makes the problem hard.Fortunately, you don't have to figure that out. You have all the information you need.Solution
Time it takes to Catch Tom = distance to be made up / difference in speed
Distance to be made up = 65 miles
Difference in speed = 5 mph
Time taken for michelle to catch Tom = t
t = 65/5
t = 13 hours.
Solution Two
The distance is the same when Michelle catches Tom
d = r*t
Michelle's rate = 70 mph
Michelle's time = t
Tom's rate = 65
Tom's Time = t + 1
70 * t = 65(t + 1)
70 * t = 65*t + 65
70*t - 65*t = 65
5t = 65
t = 65/5 = 13
In thirteen hours, Michelle will catch Tom

One house increases by 10000 the other decreases by 5000. You could do it using the first method above, but in this case the second is actually easier.
Juan: 200000 + 10000*t
Tia : 350000 - 5000t
When will the be equal (at what price and when?).
200000 + 10000t =350000 - 5000t Divide by 1000
200 + 10t = 350 - 5t Add 5t to both sides
200 + 10t + 5t = 350 Combine
200 + 15t = 350 Subtract 200 from both sides
15t = 150 Divide by 15
t = 150/15
t = 10 years
In the year 2006, a person bought a new car for $18000. For each consecutive year after that, the value of the car depreciated by 15%. How much would the car be worth in the year 2009, to the nearest hundred dollars?
Please i need answer now
Answer:
Step-by-step explanation:
Use the exponential function
[tex]v(t)=a(b)^t[/tex] where a is the initial value of the car, b is the rate of decay, and t is the time in years. For us, a = 18000, b = (1 - .15), so the model for this car is:
[tex]v(t)=18000(.85)^t[/tex] We can use this model now to find the value, v(t), of the car after 3 years has gone by (from 2006 to 2009 is 3 years):
[tex]v(t)=18000(.85)^3[/tex] and simplifying a bit:
v(t) = 18000(.614125) so
v(t) = 11054.25
Round however you need to.

Suppose that of 2000 students, 1100 take math, 500 take science, and 300 students take both math and science. What is the probability that a student selected at random takes math or science?
Answer:
4/5
Step-by-step explanation:
Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.
For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one is attached to the event. If it doesn't a value of zero is attached to the event.
probability that a student selected at random takes math or science = probability a student takes maths + probability a student takes science
probability a student takes maths = number of maths students / total number of students
probability a student takes science = number of science students / total number of students
(500 / 2000) + (1100 / 2000) = 1600/2000 = 4/5

Write an equation for the total water usage, U, at the park this year in terms of x, the number of special events the park has hosted
Answer:
U = 16206 + 22.2x
Step-by-step explanation:
This year, water usage has increased by 20% for both regular days and special events.. Write an equation for the total water usage, U, at the park this year in terms of x, the number of special events the park has hosted
Solution:
Last year regular usage of water was 13505 gallons, where as it was 18.5 gallons per special event. Let us assume that there were x special invents, hence:
The total usage for last year = 13505 + 18.5x
This year, the total usage (U) increased by 20%, hence:
Total usage for this year (U) = total usage for last year + 20% of total usage for last year
U = (13505 + 18.5x) + 0.2(13505 + 18.5x)
U = 13505 + 18.5x + 2701 + 3.7x
U = 16206 + 22.2x
In a certain video game, players earn bonus points after finishing a
level. The number of bonus points is based on how many seconds, t,
it takes the player to finish the level. The game uses the expression
-5.5 + 500+ 0.9t + (1 - 1.9t to determine the number of bonus points. .
Zahara finishes a level in 201 seconds. How many bonus points does she earn?
Answer:
If Zahara finishes a level in 201 seconds, she earns:
294.5 pointsStep-by-step explanation:
To identify the number of points that Zahara obtained when she finished a level in 201 seconds, you must use the given expression:
-5.5 + 500+ 0.9t + (1 - 1.9t)Where:
t = time in seconds.As Zahara took 201 seconds to finish a level, we're gonna replace this value in the equation:
-5.5 + 500+ 0.9t + (1 - 1.9t)-5.5 + 500+ 0.9(201) + (1 - 1.9[201]) (we're not use the unit "seconds", because we don't need it in this calculation)-5.5 + 500+ 180.9 + (1 - 381.9)-5.5 + 500+ 180.9 - 380.9 (You can organize the numbers is you want)500 + 180.9 - 380.9 - 5.5294.5 pointsAs you can see, Zahara obtains 294.5 points if she finishes the level in 201 seconds.
