When multiplying exponent, you subtract the exponents
True or false?
Answer:When multiplying powers with the same base, you subtract the exponents. When dividing powers with the same base, you multiply the exponents
Step-by-step explanation:
1/5 x = 20 solve for x
Answer: x=100
Step-by-step explanation:
Let's start by multiply 1/5 on both sides to cancel it out with the x
1/5x=20
(1/5) (1/5)
x=100
1/5 MULTIPLIED BY 20 CAN ALSO BE 5 TIMES 20!
A zookeeper takes care of 5 mountain lions. The keeper orders
32.5 pounds of meat for them each day. Each mountain lion receives
the same amount. What equation can you use to find how much meat
each mountain lion eats in a day?
Answer:
y=32.5÷5
Step-by-step explanation:
the 32.5 lbs of meat is distributed between 5 lions so 32.5÷5=y
find the equation that represents the proportional relationship between in this graph
Answer:
y = 2x
First, we need to find a point on the graph that the line goes through. (1, 2) is an example we can use because the line goes through the point (1, 2). Now, we need to see how high the point (1, 2) is from the X axis. (1, 2) is 2 units away from the X axis. Now, we need to find out how far it is from the Y axis. (1, 2) is 1 unit away from the Y axis. Now, the formula for slope is Distance of Y/ Distance of X. So, we just plug in our values to get 2/1, or 2. We know that the slope - intercept formula is y = mx + b. M is the slope, B is the Y intercept. Since there is no Y intercept, we can put 0 for Y intercept. Slope is 2, so formula is Y = 2x.
The slide at the playground has a height of 5 feet.
The sliding board is 13 feet long. How far away
from the ladder is the bottom of the slide?
Answer:
Assuming the slide is straight - 12 feet
Step-by-step explanation:
Assuming the slide is straight - it creates a right triangle with long side 13 feet and one of the short sides of 5 feet. We need to find the other short side.
We know that:
[tex]x^2 + 5^2 = 13^2\\x^2 + 25 = 169\\x^2 = 144\\x = 12 \vee x = -12\textrm{; but -12 doesn't make sense}[/tex]
Bob, the plumber, charges the cost of materials as his labor fee. If his current job
has a material cost of $130, how much will Bob charge his client (including his labor feel?
Answer:
$162.5
Step-by-step explanation:
162.5 dollars because you divide the cost of materials by 4 and add that to 130

I’M MAKING BRAINLIEST!!!!
Step-by-step explanation:
Make a table to find the values of x
P.s pick random y value
When x is 1,
y is 4........ Plug 1 into the equation ur given u get the value of y. So, 2(1)+2
When x is 2,
y is 6......... Plug 2 into the equation ur given u get the value of y. So, 2(2)+2
So this point is (2,6)
When x is 3
y is 8 ......2(3)+2
So this point is (3,8)
When x is 4
y is 10.... 2(10)+2
So this point is (4,10)

Find the base area of a cone with a volume of 75 cubic inches and a height of 6 inches.
Answer:
(75/2) in^2, or approximately 37.5 in^2
Step-by-step explanation:
The equation for the volume of a cone of base area b and height h is
V = (1/3)(b)(h).
Let's solve this for b, since b is the unknown here.
Multiplying both sides of this equation by 3, we get:
3V = (b)(h), and so
b = (3V)/h
In this particular case we're given V = 75 in^3 and h = 6 in. Substituting these values into the above formula for b, we get:
3(75 in^3)
b = ------------------- = (75/2) in^2, or approximately 37.5 in^2
6 in

This year Rachel watched 60 movies. She thought that 57 of them were very good. Of the movies she watched, what percentage did she rate as very good?
Answer:
95%
Step-by-step explanation:
The percentage that Rachel rated as very good is calculated as:
The number that she thought was very good/ Total number of movies × 100
The number that she thought was very good = 57 movies
Total number of movies = 60 movies
Hence,
57/60 × 100
= 95%
The percentage that Rachel rated as very good is 95%

An experiment to test the effectiveness of regular treatments with fluoride varnish to reduce tooth decay involved 36 volunteers who had half of their teeth (the right side or left side, determined by a coin flip) painted with a fluoride varnish every six month for 5 years. At the end of the treatments, the number of new cavities during the treatment period was compared on treatment (fluoride varnish) side versus the control (no fluoride varnish) side. The appropriate statistical test for analyzing the results of this experiment is
Answer:
One-sample t-test on paired data.
Step-by-step explanation:
Here, two different measures or reading were obtained for the two treatment (fluoride vanish) and the control (no fluoride vanish). However, this two measurement were obtained from each of the observations or subjects, hence why it is called one sample t-test on paired data. This would allow the effectiveness of the floiride vanish treatment on each the subjects teeth as we'll have two different data (fluoride vanish treatment) and control treatment on each the subjects employed for the study.

Answer:
last option: 9200 + 80c ≤ 25,000
Step-by-step explanation:
the options showing ≥ 25,000 cannot be solutions because the weight must be less than 25,000
if there already is 9200 then that would be added to 80c and, when solved, would tell you how many 80kg containers can be loaded
80c ≤ 25,000 - 9,200
80c ≤ 15,800
c ≤ 15,800 ÷ 80
c ≤ 197.5

Mason recently bought seven boxes. A week later half of all his boxes were destroyed in a fire. There are now only 22 boxes left. With how many did he start with
Step-by-step explanation:
if mason had recently bought seven boxes and half of them got destroyed in a fire which is 1/2, and there are now only 22 boxes left soo im
using based on the info it gave me sorry if its wrong
-Find the final amount of boxes left:
-If mason had bought in seven boxes recently and after 1/2 if gone and results in 22 that should be in logic 44 since 22×2=44
-to find the box he started with when he also bought in 7 boxes we should be 37 and then add 7 to get 44
The final answer is : 44
