Answer:
21 Months
Step-by-step explanation:
If he already has $225, we can do 750 - 225 to get 525. $525 represents how much more money he needs to reach his goal of $750. So we can do 525 divided by 25, since that is how much he makes per month, giving us 21. 21 is how many months it will take until he gets to $750 without spending anything.
An electrician completes 1/6 of a job in 2/3 hour. How long does it take the electrician to complete the job?
Answer:1/4
Step-by-step explanation:
express 7.84684846 as a rational number in the form p/q were p and q have no common factors
It's not clear what the pattern is supposed to be for the digits in the givne number. It looks like the repeating block should be 846, but it could just as easily be 84684.
Assume the first case, and let x = 7.846846846... . Then
1000x = 7846.846846846...
Subtract x from this to cancel the repeating decimal part, then solve for x :
999x = 7846 - 7 = 7839
x = 7839/999 = 871/111
If instead you meant the second case, let x = 7.846848468484684... . Then
10⁵ x = 784,684.846848468484684...
Solve for x :
99,999 x = 784,684 - 7 = 784,677
x = 784,677/99,999 = 261,559/33,333
Maybe you meant something else altogether?

Need help with this right now, please.
Answer:
see below
Step-by-step explanation:
the circumference of a circle is
[tex]2\pi r[/tex]
in our problem
r=11
[tex]C=2\pi (11)\\\\=22\pi[/tex]
rounded to the nearest tenth
[tex]C\approx69.1[/tex]
the area of a circle is
[tex]\pi r^2[/tex]
so the area is
[tex]A=\pi(11)^2\\\\=121\pi[/tex]
rounded to nearest tenth
[tex]A\approx 380.1[/tex]
Which problem can be solved using this equation .15m + 35=.25. + 20
slove for x 3x-24=81
Answer:
15
Step-by-step explanation:
Answer:
x = 35Step-by-step explanation:
[tex]3x-24=81[/tex]
Collect like terms and simplify
[tex]3x=81+24\\\\3x = 105[/tex]
Divide both sides of the equation by 3
[tex]\frac{3x}{3} = \frac{105}{3} \\\\Simplify\\\\x = 35[/tex]
Jenna buys water from a store which allows you to bring your own containers of water and fill them up. The only catch is that you must honestly type into the store's computer how many gallons of water you took in total, written as a decimal, and then pay the amount the computer indicates.
Today, Jenna takes four containers with her. The first has a 3/4 gallon capacity, the second has a 1/8 gallon capacity, the third has a 4/5 gallon capacity, and the fourth has a 17/125 gallon capacity. She fills up all of the containers with water. What decimal should Jenna type into the computer?
Answer:
1.811
Step-by-step explanation:
To get the decimal Jenna should type into the computer you simply have to get the decimal value of each fraction and add them all together.
[tex]\frac{3}{4}=.75[/tex]
[tex]\frac{1}{8} =.125[/tex]
[tex]\frac{4}{5}=.8[/tex]
[tex]\frac{17}{125}=.136[/tex]
Then just add all the decimals together.

Answer:
(x+5)(x+5)
Step-by-step explanation:
Let's arrange it in a proper manner first of all.
x² + 10x + 25Step: Spilt 10x in order to factorize it.
x² + 10x + 25
0r, x² + 5x + 5x + 25
Step: Make two pairs from equation
x² + 5x + 5x + 25
0r, x(x+5) + 5(x+5)
Step: Take common thing from the given equation
x(x+5) + 5(x+5)
0r, (x+5)(x+5)
Hence, (x+5) and (x+5) are the factor for the given equation.

The triangles below are similar. Find DE. If necessary, round 2 decimal places.
Answer:
9.75
We know that the 2 triangles are proportional and are similar so that means there must be a scale factor between the sides of the triangles.
Which number produces an irrational number when multiplied by 0.5
A.
[tex] \sqrt{16} [/tex]
B. 0.555...
C.
[tex] \sqrt{3} [/tex]
D. 1/3
Answer:
C. √3
Step-by-step explanation:
When one of the factors is a rational number (0.5), the product will be irrational if, and only if, the other factor is irrational.
Of the numbers offered, only √3 is irrational.
√3 will produce an irrational product when multiplied by 0.5.

The other values are all rational:
A: 4
B: 5/9
D: 1/3

1.5 lbs of gum balls I want to buy it’s 3.99 per pound
Answer:
$5.99 for 1.5 lbs of gumballs
Step-by-step explanation:
You want to buy One and a half pounds of gumballs for $3.99 per pound. It is 3.99 for one pound of gumballs, so the price for half a pound of gumballs is half of that price.
3.99 / 2 = 1.995
Then add the price of 1 pound
3.99 + 1.995 = 5.985
Then you can round that up to 5.99

what is the polar form of 7 √ 3-7i
Answer:
14(cos(330)+isin(330))
Step-by-step explanation:
step1: determine the modulus using the formula |z|=√(a²+b²)
|z|= √((7√3)² + (-7)²) = √196 = 14
step2: determine the argument using the formula θ=tan⁻¹(y/x)
θ= tan⁻¹(-7/7√3) = (-1/√3) --> rationalize the denominator by multiplying top and bottom by √3 to get: -√3/3
the tangent value on the unit circle that is -√3/3 is 330 degrees in quadrant iv
then put it together :p

a. 228
b. 229
c. 172
d. 171
Answer:
I think its 229
if you take how many yellow marbles he got out of 7 it would be 3/7 and then I divided 400 by 7 and got 57. something so I multiplied 3 times 57 and got 171. So if you take 400-171 you get 229
Solve for x. Show each step of the solution 4.5 ( 8 - x ) + 36 = 102 - 2.5 ( 3x + 24)
Answer:
X=-10
Step-by-step explanation:
Answer:
x = -10
Step-by-step explanation:
4.5(8-x) + 36 = 102 - 2.5(3x+24)
36 - 4.5x + 36 = 102 - 7.5x - 60
72 - 4.5x = 42 - 7.5x
72 + 3x = 42
3x = -30
x = -10
