Answer:
pretty sure its C. hope i helped
Answer:
B.
Step-by-step explanation:
When dividing fractions, use the KCF method or Keep it, Change it, Flip it.
1. Keep the first fraction.
2. Change the division sign to multiplication.
3. Flip the fraction, and use the reciprocal instead (in this case, 13/17 would become 17/13).
The correct answer would be b. 5 & 6/11 x 17/13

Answer: 31.42
Step-by-step explanation:
Money was placed in a savings account and earned 3/4 % interest paid annually. Samantha, Tony and Anuyia each wrote an equation to show the amount of money in the account after one year with a balance of M dollars. T represents the total amount of money in the account.
Samantha’s Equation: T = 1.075M
Tony’s Equation: T = M + 0.0075M
Anuyia’s Equation: T = M(1 + 0.0075M)
Since none of the equations were written the same, they decided to see if their equations would give the same answers by using a $75 balance. Solve this problem using each student’s equation.

Answer:
22
Step-by-step explanation:
20+ 20% =22
20% is 0.2 so your answer is 22 dollars
The lengths of two sides of a right angled triangle are 20 cm and 30 cm.
Calculate the length of the third side, if it is:
(a) the hypotenuse
(b) not the hypotenuse
Answers:
Part (a) 10*sqrt(13) Part (b) 10*sqrt(5)Those values are exact. They approximate to:
10*sqrt(13) = 36.0555
10*sqrt(5) = 22.3607
====================================================
Explanation:
Part (a)
If the unknown third side is the hypotenuse then we need to find the value of c when a = 20 and b = 30.
Apply the pythagorean theorem
a^2 + b^2 = c^2
20^2 + 30^2 = c^2
400 + 900 = c^2
1300 = c^2
c^2 = 1300
c = sqrt(1300)
c = sqrt(100*13)
c = sqrt(100)*sqrt(13)
c = 10*sqrt(13) .... exact length
c = 36.0555 ...... approximate length
------------------------------------
Part (b)
If the third side is not the hypotenuse then that must mean c = 30 is the hypotenuse as this side is larger than the 20 cm side. The hypotenuse is always the longest side.
Let a = 20 be the known leg. Let's find the other unknown leg b using the pythagorean theorem.
a^2 + b^2 = c^2
20^2 + b^2 = 30^2
400 + b^2 = 900
b^2 = 900-400
b^2 = 500
b = sqrt(500)
b = sqrt(100*5)
b = sqrt(100)*sqrt(5)
b = 10*sqrt(5) ..... exact length
b = 22.3607 ....... approximate length
Veronica used a copy machine to make an entargement of a triangle. The original triangle has side lengths of 6 cm, 8 cm, and 10 cm. The
copy has side lengths of 7.2 cm, 9.6 cm, and 12 cm.
Which scale factor did Veronica use to make the enlargement?
A: 5/8
B:5/6
C:6/5
D:8/5
Answer:
Step-by-step explanation:
B 10/12 = 6/7.2 = 8/9.6 = 5/6
Answer:
The anwser is C: 6/5
Step-by-step explanation:
12 divided by 10 = 1.2 = 6/5
9.6 divided by 8 = 1.2 = 6/5
7.2 divided by 6 = 1.2 = 6/5

It takes the Sun about 2.3x10^8 years to orbit the center of the Milky Way. It takes Pluto about 2.5 times 10 squared years to orbit the Sun. How many times does Pluto orbit the Sun while the Sun completes one orbit around the Milky Way?
if equals c 10 five dndsndndn
It takes the Pluto about 14.375 x 10¹⁰ years to orbit the Sun while the Sun completes one orbit around the Milky Way
What is multiplication?Multiplication is a mathematical arithmetic operation. It is also a process of adding the same types of expression for some number of times.
Example - 2 × 3 means 2 is added three times, or 3 is added 2 times.
Given:
It takes the Sun about 2.3x10⁸ years to orbit the center of the Milky Way.
It takes Pluto about 2.5 times 10 squared years to orbit the Sun.
Pluto orbits the Sun while the Sun completes one orbit around the Milky Way,
= 2.3 x 10⁸ x (2.5 x 10)²
= 14.375 x 10¹⁰
Therefore, the required time is 14.375 x 10¹⁰ years.

a=1/2pa, solve for p
NO LINKS PLEASEE!! IM BEGGING YOU NO LINKSS!!!
Answer:
A = (1/2)Pa = Pa/2
You can multiply both sides by 2 to eliminate the fraction on the right side:
2A = 2(Pa/2) = Pa
Then divide both sides by a (or multiply both sides by 1/a) to leave P alone on the right side:
(2A)(1/a) = 2A/a = (Pa)(1/a) = P
Rewriting:
P = 2A/a
You could also have divided by a first then multiplied by 2; which you should do first does not matter in this example.

Step-by-step explanation:
6(x + 3) = 21
6x + 18 = 21
6x (+18 - 18) = 21 -18
6x = 3
6x/6 = 3/6
x = 0.5
6 (0.5 + 3) = 21
6(3.5) = 21
21 = 21
Find the value of x:
Answer:
x = 3
Step-by-step explanation:
These angles are vertical angles. Vertical angles equals to on another but on the opposite side. Since they equal to another you do:
(10x + 1) = (12x - 5)
Add 5 on both sides:
10x + 6 = 12x
Subtract 10x on both sides:
6 = 2x
Divide 2 on both sides:
3 = x
Answer:
(10x+1)°=(12x-5)°. [vertically opposite angle]
1+5=12x-10x
6= 2x
3=x
therefore,x=3
