Answer:
4/5
Step-by-step explanation:
Since we know that the first ratio that we have is 16:20, all you have to do is simplify by dividing and you get 4/5.
There you go.
Farah's brother is 7 years less than twice Farah's age, f. The sum of Farah's age and

- -4(-3n - 8) = 104
Divide both sides by -4!
-4(-3n - 8) over -4 = 104/-4
Simplify!
-3n - 8 = -26
Add 8 to both sides!
-3n - 8 + 8 = -26 + 8
Simplify!
-3n = -18
Divide both sides by -3!
-3n/-3 = -18/-3

Consider the division expression LaTeX: 7\frac{1}{2}\div27 1 2 ÷ 2. Select all multiplication equations that correspond to this division expression.
Answer:
2 x ? = 7 1/2 and ? x 2 = 7 1/2
Step-by-step explanation:
This is the answer because it didn't show the answer so all you have to figure out is the multiplication problem that goes with the division problem. So 2 x ? = 7 1/2 and ? x 2 = 7 1/2 you don't have to include the answer all you have to include is where the answer will do if you DID have the answer. These two are correct because the multiplication number can go in any order.
I know this might not be the best step-by-step explanation ever but I truly tried but the answer is correct.
N=480×10^9
Write N as a product of powers of its prime factors.
Answer:
I got 5^10 x 2^14 x 3
Step-by-step explanation:
1. Do a tree to find 480 as a product of its prime factors
2. You should get 480= 5x2x3x2x2x2x2
3. 10 expressed as a product of its prime factors is 5x2
4. so 10^9 expressed as a product of its prime factors would be
5x2x5x2x5x2x5x2x5x2x5x2x5x2x5x2x5x2
5. You can then write out 480x10^9 as a product of its prime factors
5x2x3x2x2x2x2x5x2x5x2x5x2x5x2x5x2x5x2x5x2x5x2x5x2
6. change this to use powers
5^10 x 2^14 x 3
N = 5^(10) × 2^(14) × 3
This is about prime factors
By definition, a prime factor is a factor of a number and that factor is also a prime number.
A prime number is one that is divisible by only itself and 1.
The number we have is; 480 × 10^(9)
Now, let's list the prime factors or 480 and they are;
2, 3, 5
Now, using these prime factors alone to get 480, we have;
5 × 3 × 2 × 2 × 2 × 2 × 2 = 480
In powers, gives;
5 × 3 × 2^(5)
Now,the 10^(9) with the 480 can also be expressed in terms of it's prime factors which are 2 and 5 as;
(5 × 2)^(9)
Expanding this gives; 5^(9) × 2^(9) = 10^(9)
Thus;
480 × 10^(9) = 5 × 3 × 2^(5) × 5^(9) × 2^(9)
This gives;
5^(10) × 2^(14) × 3

Can someone help??? PLEASE
Answer:
1) Measure angle QWT and TWX are complementary because their measures add up to 90 degrees.
2) Both measure angles add up to 90 degrees because they're complementary.
3) Angle QWT = 2x and angle TWX = x + 6, and since angles QWT + TWX = 90 then 2x + x + 6 = 90.
4) (Made up?:) Angle measure QWX = 90. The quarter-turn, or the small square, indicates that the angle is 90 degrees.
5) (?)
6) x = 28 because it fulfills the equation, 2x + x + 6 = 90, or 3x + 6 = 90. 90 - 6 is 84, and 84/3 is 28.

Howard bought 3/5 pound of granola. He divided the
granola evenly among 4 friends. How much granola did
each friend get?
Answer:
Step-by-step explanation:
So because Howard wants to divide the granola evenly among all of his friends, we have to divide the amount of pounds he has by the number of friends he has.
(3/5) / 4
Dividing by four is the same as multiplying by the reciprocal of 4 which is 1/4.
So (3/5) * (1/4) is 3/20 which is .15 pounds

Your parents gave you $20 to spend at the book fair. You are getting the new Diary of the Wimpy kid book that costs $8.99/ If pencils and erasers cost $0.79 each, what is the maximum you can buy with the money provided?
Answer:
You can buy a maximum of 13 erasers/pencils.
Step-by-step explanation:
Your total is 20 dollars. The book cost 8.99, so you take away that amount from 20, getting you 11.01. You have $11.01 left. Then you divide your total (11.01) by the price of each eraser (0.79). This gets you 13.9367088608. Since thats not an even number, you have to round down because you don't want a broken pencil?eraser.

What is the area of major sector DFE?
Answer:
B. 171.74 cm²
Step-by-step explanation:
Area of a sector = [tex] \frac{\theta}{360} \times \pi r^2 [/tex].
Where,
[tex] \theta = 260 [/tex]
radius (r) = 8.7 cm
Plug in the values into the formula
Area of sector = [tex] \frac{260}{360} \times \pi 8.7^2 [/tex]
Area of sector = [tex] \frac{260 \times \pi 75.69}{360} [/tex]

Sammy has included a total row to help make sure that his paycheck can be divided to make deposits into these 4
Answer:
B
Step-by-step explanation:
Based on the amount that Sam saves and his living expenses, the amount he needs to save and the length of time it will take him to do so is B. 5,136; Approximately 24 months.
What are Sam's living expenses?= Fixed essential expenses + Variable essential expenses
= 1,292 + 420
= $1,712
How much does Sam need to save?Sam needs to save three times his expenses:
= 1,712 x 3
= $5,136
How long will it take Sam to save this amount?= Amount to be saved / Amount saved monthly
= 5,136 / 210
= 24 months approximately.
________________________________________________________
The question is:
Using his essential expenses as a guideline, how much will Sammy need to save if he wants to have 3 times the amount of his living expenses in the bank as part of his emergency savings. How long will it take him to achieve his goal?

Solve the equation using inverse operations. Check your solutions. In you final answer, include all of your work.
Answer:
x = ±6
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesAlgebra II
Extraneous solutions and multiple answers/rootsStep-by-step explanation:
Step 1: Define
-x² = -36
Step 2: Solve for x
Divide -1 on both sides: x² = 36Square root both sides: x = ±6Step 3: Check
Plug in x to verify it's a solution.
Substitute in -6: -(-6)² = -36Exponents: -(36) = -36Multiply: -36 = -36Substitute in 6: -(6)² = -36Exponents: -(36) = -36Multiply: -36 = -36Here we see that both -6 and 6 do indeed work as solutions.
∴ x = ±6 are both solutions to the equation.

X-8y = -10
Answer:
{x,y}={31,4}
Step-by-step explanation:
x-8y = -1 x-6y = 7
Answer:
first we find the value of 'y' so
x-8y=-10+8y
x=-10+8y
-2(-10+8y)-6y=-24
20-16y-6y=-24
20-22y=-24-20
-22y=-44
y=2
then also we can find the value of 'x'
-2x-6y=-24
2x-6(2)=-24
2x-12= -24
2x= -24+12
x= -12
