what is the value of f
Answers
Answer:
f = 22
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
140° is an exterior angle of the triangle, thus
4f + 1 + 51 = 140, that is
4f + 52 = 140 ( subtract 52 from both sides )
4f = 88 ( divide both sides by 4 )
f = 22

HELP 66 hundreds÷10 Choose 1 answer: (Choice A) A 66 \text { thousands}66 thousands66, start text, space, t, h, o, u, s, a, n, d, s, end text (Choice B) B 66 \text { ones}66 ones66, start text, space, o, n, e, s, end text (Choice C) C 66 \text { tens}66 tens
Answers
Answer:
66 tens
Step-by-step explanation:
Required
Solve 66 hundreds / 10
First, we need to express 66 hundreds as a number.
1 hundred = 100
66 hundreds = 66 * 1 hundred
So:
66 hundreds = 66 * 100
66 hundreds = 6600
66 hundreds / 10 would then be calculated as:
66 hundreds / 10 = 6600/10
66 hundreds / 10 = 660
660 can be represented as:
66 hundreds / 10 = 66 * 10
or
66 hundreds / 10 = 66 tens

We add the total number of hours together
1 hour 50 minutes + 2 hours 25 minutes + 1 hour 20 minutes

Which value is a perfect square? 12 24 49 63
Answers
Answer: 49 is a perfect square.
Step-by-step explanation: We say that 49 is a perfect square because it is the product of an integer multiplied by itself, 7×7. If we had a square with an area of 50, this wouldn't be a perfect square because no integer, multiplied by itself, will give a product of 50.

Mateo has been studying after school while preparing for a test retake. His work paid off ! His score on the retake was a 94. This was quite a difference from the grade on his first attempt which was a 68. What is the approximate percent of change between the two tests?
Answers
Answer:
28%
Step-by-step explanation:
We know that 100 percent is total. Mateo first scored 68/100, then a retake got his score up to 94/100.
First, subtract the two numbers
94 - 68 = 26
Put 26 over 94 to make this 26/94
Divide to get 0.28 (simplified and rounded)
So the increase was 28%
Answer:
increase of 28?
Step-by-step explanation:
Okay so, I believe it is 28, let me explain. First, work out the difference (decrease) between the two numbers you are comparing. Next, divide the decrease by the original number and multiply the answer by 100. If the answer is a negative number, this is a percentage increase.

Answers
Answer:
m=−16
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
4m−5(3m+10)=126
4m+(−5)(3m)+(−5)(10)=126(Distribute)
4m+−15m+−50=126
(4m+−15m)+(−50)=126(Combine Like Terms)
−11m+−50=126
−11m−50=126
Step 2: Add 50 to both sides.
−11m−50+50=126+50
−11m=176
Step 3: Divide both sides by -11.
−11m /−11 = 176 /−11
m=−16
