Answer:
V=4/3πr³
but V is given = 4/3.73
4/3.73 = 4/3πr³
4×3πr³=4×3.73
12πr³=14.92
12πr³÷12π=14.92÷12π
r³=0.3957..
³√r³ = ³√0.3957
r= 0.7341..

Answers
Answer:
(x+x)^2=4-x
Step-by-step explanation:
I think, don't be mad if I'm wrong!
The approach used seems to be:
Step 1: Make the first term x^2 not 2x^2, by dividing every term by 2.
x^2 + 1/2 x - 2=0
Note here that because the computer had “+” before the second box in the first line, you needed to put “-2” instead of 2 to keep the sign correct.
Step 2: Move that -2 to the other side and then figure out what you’re going to add to the right side to complete the square. The way you do this is you take the “b” value from “bx” and divide it by 2 and square it.
Divide b by 2: 1/2 ÷ 2 = 1/2 • 1/2 = 1/4
Square that: (1/4)^2 = 1/16
So you need to add 1/16 to both sides.
The final step is to factor the left side and add the numbers on the right side.
Left side: x^2 + 1/2x + 1/16 = (x+1/4)^2.
The 1/4 can be found either by dividing the “b” by 2 or taking the square root of 1/16. Both give you 1/4.
You can always double check your work by FOILing out (x+1/4)^2 as (x+1/4)(x+1/4) and making sure you get used 1/4 correctly.
On the right side, 2 + 1/4 = 2/1 + 1/4 = 8/4 + 1/4 = 9/4
You need to find a common denominator to add them.
The above process will always work. How messy it is totally depends on the numbers involved.

(a) Prove that cos 3A = 4cos³ A - 3 cos A
Answers
Answer:
Step-by-step explanation:
cos 3A = cos (2A+A)
= cos 2A cos A - sin 2A sin A
= (2cos[tex]A^{2}[/tex] -1) cos A - (2sinAcosA) sinA
=2cos[tex]A^{3}[/tex]-cosA - 2sin[tex]A^{2}[/tex]cosA
=2cos[tex]A^{3}[/tex]-cosA -2(1 -cos[tex]A^{2}[/tex])cosA
=2cos[tex]A^{3}[/tex] - cosA - 2 cosA+ 2cos
⇒ ∴4cos[tex]A^{3}[/tex] -3 cosA
susie bought 4 hair bows for 0.50 each which equation shows how to find the total cost in dollars and cents of the hair bows bought
Answers
Hi! I'm happy to help!
We need to look for clues in the problem to see which operation we are going to use. We see the word each, which represents multiplication.
So, we will multiply 4 by 0.50 to get our cost.
4×0.5
2
So, the cost of the 4 hair bows is $2.00.

Bob is filling his 7000-gallon swimming
pool. His hose fills at a rate of 22.2
gallons per minute. To the nearest
minute, how long will it take to fill his pool
Answers
Answer:
315 minutes
Step-by-step explanation:
To solve this, we must divide the gallons of the swimming pool by the rate of gallons per minute.
7,000 gallons divided by 22.2 minutes equals 315.3 minutes.
We can round this to 315.
315 minutes is how long it will take to fill the pool.

Answers
Answer:
∠1 = 64°
∠2 = 116°
Step-by-step explanation:
Let x = supplement and x + 52 = the one angle. Set up this equation:
(x) + (x + 52) = 180
2x + 52 = 180
Subtract 52 from both sides.
2x = 128
Divide both sides by 2, and you get x = 64.
Keep in mind this equals the supplement. To find the measure of the other angle, add 52 and you get 116
3 times the sum of a number and 5 is the same as -6, what is the number?

If a square root isn't a perfect square, then it is an irrational number, which means that it cannot be represented as the ratio of two integers. If we input √14 into a calculator, we can see that it would equal to a repeating decimal. √14 is an irrational number.
