Percents can be expressed as fractions and decimals. A percent means “out of 100,” so we can express 40% as the fraction 40⁄100. We can simplify this fraction to2⁄5 by dividing by the greatest common factor, 20.
We can also express a percent as a decimal. Percents show a part out of a hundred, or hundredths, so you can divide the percent by 100 to find the decimal. 40 divided by 100 equals 40 hundredths, or .4. You can also divide the numerator by the denominator in the simplified fraction, 2⁄5, to find the equivalent decimal.
These values are all equivalent.
75% =
A
75/10
B
2/3
C
3/4
D
3/5
Answer:
Definitely 3/4!
Step-by-step explanation:
Option A = 7.5
Option B = 66.6%
Option C = 75% (because 25 times 4 is equal to 100%, so 25 times 3 would be 75)
Option D = 6/10 or 60%
The values that are equivalent to 75% are A) 75/100 (0.75) and C) 3/4.
To determine whether these values are equivalent, let's evaluate each expression and compare the results.
A) 75% can be written as a decimal by dividing 75 by 100:
75% = 75/100 = 0.75
B) 2/3 is already in fractional form and cannot be simplified further.
C) 3/4 is also in fractional form and cannot be simplified further.
D) 3/5 is in fractional form and cannot be simplified further.
Now let's compare the decimal equivalents:
0.75 = 75/100
2/3 = 0.666...
3/4 = 0.75
3/5 = 0.6
Comparing the decimal values, we can see that A) 0.75 and C) 0.75 are equivalent, as they both represent 75% in decimal form.
However, B) 2/3 and D) 3/5 do not equal 0.75 and are therefore not equivalent to 75%.
Hence, the values that are equivalent to 75% are A) 75/100 (0.75) and C) 3/4.

Step-by-step explanation:
Let ∠1, ∠2, and ∠3 have the following relationships.
I WILL GIVE 20 POINTS PLS
∠1 and ∠2 are adjacent right angles.
∠1 and ∠3 are vertical angles.
What is the measure of ∠1 plus the measure of ∠3 minus the measure of ∠2?
Answer: If 1 and 2 are adjacent right angles, they are both 90º.
1 and 3 are vertical, which means they must be congruent, so 3 is also 90º
So: 90 + 90 - 90 = 90

How do I do this and what’s the answer
Answer:
5x³-13x²+24x+12
Step-by-step explanation:
Start by distributing (5x+2) into (x²-3x+6)
It is easiest to start with 5x.
When distributing 5x, your answer should be: 5x³-15x²+30x.
Then, distribute the 2 just as you did for 5x.
Your answer for that should be: 2x²-6x+12
After that, add the like- terms from both answers together.
5x³-15x²+30x+2x²-6x+12
The final answer is then: 5x³-13x²+24x+12

15/8 also division (long division...) 15 divided by 8
you will have a remainder (that will become your numerator)
the decimal of that division is 1.875 as a fraction that is a mixed number:
8 AND 875/1000 but!! you are not done yet (that fraction has to be simplified)
If you divide the fractional portion by the greatest common factor (125) you can simplify your fraction to 8 7/8
13/6 is 13 divided by 6 = 2 with a remainder of 2 = 2 2/6 simplified = 2 1/3

Step-by-step explanation:
Tom is applying for a visa. He has to pay £1,700 for the visa as well as a 11% charge on the visa price for an on-the-day service. If Tom has 1 year to save, how much money should he save per month to be able to cover his costs? Round your answer to the nearest £10.
Step-by-step explanation:
this is geometric sequence
G1=Go(1+r)^n
G1=1700(1+11%)^1
G1=1700(1+0.1)
G1=1700*0.1
G1=170 per year
G1=170*12 per month
G1=2040
