Step-by-step explanation:
A tv costs $215 and has a 30% increase. What is the amount of increase? Show your work
i well try to give brainlist for first to answer correctly
Answer:
The price increased by 64.5, which makes a total of 279.5
Step-by-step explanation:
215*0.30 = 64.5
215 + 64.5 = 279.5
0.30 = 30% of 100
When you multiply by 0.30 you get 30%, or with any decimals, like multiply by 0.50 to get 50% of something, etc.

In ΔMNO, the measure of ∠O=90°, MN = 99 feet, and OM = 26 feet. Find the measure of ∠M to the nearest tenth of a degree.
Answer:
74.8
Step-by-step explanation:
Cos M = adjacent/hypotenuse = 26/99
M = [tex]Cos^{-1}[/tex](26/99)
M = 74.774 ≅ 74.8
Answer:
74.8 is the correct answer

The measure of an angle is nine times the measure of its complementary angle. What is the measure of each angle?
Answer:
the angle is 81 and it's complementary angle is 9
let X be the angle
let 90-x be it complementary angle
so X=9(90-x)
X=810-9x
810=10x
X=810/10
X=81
and complementary angle 90-x which is 90-81 is equal to 9...

Step-by-step explanation:
Which statement is true?
Answer:
Step-by-step explanation:
x-intercept -> when y = 0
f(x) x-intercept -> (1 , 0)
g(x) x-intercept -> (-1 , 0)
y-intercept -> when x = 0
f(x) y-intercept -> (0 , -1)
g(x) y-intercept -> (0 , 1)
The x-intercept of f(x) is greater than the x-intercept of g(x)
The y-intercept of g(x) is greater than the y-intercept of f(x)
So from the options, the answer is D. The x-intercept of f(x) is greater than the x-intercept of g(x)

PLLLLLLLSSSSSSS HELP MEEE!!!!! I AM STUCK ON THIS AND I NEED HELP I NEED ANSWER AND WORK IF U GET IT RIGHT I WILL GIVE BRAINLIEST. If the perimeter of a rectangle is 26x^2+16x+10 and the length is 8x^2+6x+4, what is the width?
Answer:
2(3x2 + 6x - 10) + 2(3x + 5)
Step-by-step explanation:
Answer:
Lol. Give brainliest to the other guy.
Step-by-step explanation:
To find the width, multiply the length that you have been given by 2, and subtract the result from the perimeter. You now have the total length for the remaining 2 sides. This number divided by 2 is the width.

About Carrier culture initially contains 2500 bacteria and doubles every half hour
Answer:
A bacteria culture initially contains 2500 bacteria and doubles every half hour. The formula for the population is p(t)=2500e^(kt) for some constant k. Find the size of the bacterial population after 100 minutes. Find the size of the bacterial population after 4 hours.
Step-by-step explanation:
Answer:
1. 10000 bacteria
2. 640000 bacteria
Step-by-step explanation:
2500 bacteria: 30 minutes
x bacteria: 60 minutes
The bacteria gets doubled twice
2500*2*2=10000
x bacteria:240 minutes
The bacteria gets doubles 8 times
2500*2*2*2*2*2*2*2*2= 640000
How do you know if the graph will be dotted or solid when graphing linear inequalities?
Answer: look at the symbols <, > and <=, >=

A few friends went bowling. The scores
are given below. Use the scores to
calculate the range of the data. *
(1 Point)
104, 117, 104, 136, 189, 109, 113, 104
Answer:
The range here is 85
Step-by-step explanation:
Here, we want to calculate the range of the data
Mathematically, the range is defined as the difference between the lowest value and the highest value in the dataset
From the given data points, the highest value is 189, while the lowest value is 104
So the range is the difference between the two which is;
189-104 = 85
Compare Texas to Carolina. Write the answer in scientific notation. Texas= 2.5x10 to the power of 5. Carolina= 1.2x10 to the power of 3.
Answer:
Texas is 2.08333 * 10^2 times the size of Carolina.
Step-by-step explanation:
Given :
Given that:
Texas= 2.5x10^5
Carolina = 1.2x10^3
Comparing the size of Texas and Carolina
Texas / Carolina
(2.5 * 10^5) ÷ 1.2 * 10^3
(2.5/1.2) * 10^5-3
2.08333 * 10^2
Hence, Texas is 2.08333 * 10^2 times the size of Carolina.
