Einstein once developed the formula, E = mc2, to describe the theory of relativity, where E is the total energy in the system, m is the total mass, and c2 is the speed of light. If the equation was to be rearranged in order to solve for the total mass, which formula below should be used?
A - m = E/c2
B - m = E — c2
C - m = Ec2
D - m = E + c2
Answer:
The formula which should be used is [tex]m=\frac{E}{c^{2}}[/tex] ⇒ A
Step-by-step explanation:
To solve an equation of different variables to one of these variables do that
Write the equation and underline the variable you want to solve for itSeparate this variable on one side and all other terms on the other sidesLet us do that with the question
∵ E = mc²
→ E is the total energy
→ m is the total mass
→ c² is the speed of light
∵ We need to solve the equation for the total mass m
→ We need to take c² to the other side
∵ c² is multiplied by m
∴ Divide both sides by c² to move it from the right side to the left side
∴ [tex]\frac{E}{c^{2}}=\frac{mc^{2}}{c^{2}}[/tex]
→ Cancel c² with c² on the right side
∴ [tex]\frac{E}{c^{2}}=m[/tex]
→ Switch the two sides
∴ [tex]m=\frac{E}{c^{2}}[/tex]
The formula which should be used is [tex]m=\frac{E}{c^{2}}[/tex] ⇒ A
Solve for the indicated variable.
8y + 7x = 9 for x
Answer:
x = 9-8y/7
Step-by-step explanation:
8y+7x=9
Subtract 8y from both sides.
7x=9−8y
Divide both sides by 7.
7x/7 = 9 - 8y/7
Dividing by 7 undoes the multiplication by 7.
x = 9-8y/7

13. There are 48 passengers on a transit bus. At the next stop, 16 passengers got off and 12 others got on the bus.
a) What is the ratio of the passengers who got off the bus compared to the original number on the bus? Show the ratio in lowest terms.
b) What is the ratio of the passengers who got on the bus at the stop compared to the new total then on the bus?
Answer:
a) 1/3
b) 12/44
Step-by-step explanation:
To find the answer to a you must simplify the fraction 16/48 which would give you 1/3.
To find the answer to b you must first subtract 16 from 48 and then add 12. You should get 44 so your ratio of passengers who got on the bus at the stop compared to the new total then on the bus would be 12/44.

Answer:
Volume = 0.1 cu. cm.Step-by-step explanation:
p = m V
where p = 10.5 grams/cu. cm.
m = 105 grams
plugin values into the equation:
10.5 grams/cu. cm. = 105 grams V
V = 10.5 grams/cu. cm.
105 grams
V = 0.1 cu. cm.
What is the remainder when a^3 - 4 is divided by a+2?
a)0
b)-6
c)-2
d)-12
Answer:
The remainder is -12. Choice d)
Step-by-step explanation:
The Remainder Theorem
The polynomial remainder theorem states that the remainder of the division of a polynomial f(x) by (x-r) is equal to f(r).
We have the polynomial
[tex]P(a)= a^3 - 4[/tex]
To evaluate the remainder when P is divided by a+2, we only have to find P(-2):
[tex]P(-2)= (-2)^3 - 4[/tex]
[tex]P(-2)= -8 - 4=-12[/tex]
The remainder is -12. Choice d)

Annie and Ellie are each saving for college. Their grandmother gave
each of them $2500 to begin saving. Annie opened a savings account that
earns 2.4% simple interest while Ellie opened an account that earns 1.9%
interest compounded annually. In 7 years, who will have more money in
their account? How much more?*
Answer:
Annie will have $87.75 more than Ellie
Step-by-step explanation:
Annie :
2500(.024)7
Multiply all 3 together to get the answer
2500 x .024 x 7= 420
Ellie :
2500(.019)7

the absolute value of -6 symbolically
Answer:
Use the ABS function to find the absolute value of a number. The absolute value of a non-negative number (a positive number, or zero), is the same number. For example, the absolute value of 4 is 4.
Step-by-step explanation:
Explanation: The absolute value is defined as the distance from a number to 0 , and so it is always positive. So, the absolute value of −6 will be the distance from −6 to 0 on the number line, and it is 6

Let's find the critical points of the inequality.
−4x+7=17
−4x+7+−7=17+−7(Add -7 to both sides)
−4x=10
−4x−1=10−1
(Divide both sides by -1)
4x=−10
4x=−10(Solve Exponent)
log(4x)=log(−10)(Take log of both sides)
x*(log(4))=log(−10)
x=log(−10)log(4)
x=NaN

Jordan has a garden that is enclosed by a rectangular fence. The perimeter of the garden is 84 feet. The length of one side of fencing is 8 yards. What is the area of Jordan's garden?
Answer:
504 ft
Step-by-step explanation:
Perimeter = 2(width) + 2(length)
Convert yards to feet
1yard=3feet
8yards=?
8*3/1 = 24feet
84 = 2(w) + 2(24)
84 = 2w + 42
84 - 42 = 2w
42 = 2w
w = 21
Area = 1 * w
= 21 * 24
= 504 ft
Can someone pls explain the law of indices
Answer:
Indices are used to show numbers that have been multiplied by themselves. They can also be used to represent roots, such as the square root, and some fractions. The laws of indices enable expressions involving powers to be manipulated more efficiently than writing them out in full.
Using indices
An index, or power, is the small floating number that appears after a number or letter. The plural of index is indices. Indices show how many times a number or letter has been multiplied by itself.

It’s E. 64%
Step-by-step explanation:
Based on the number of people who had a car and the total number of people surveyed, the percentage is E. 64%
Percentage of those with carsThe percentage of students with a car is:
= Number of students with cars / Number of students in total x 100%
Solving gives:

Solve the following equation for a.
a-f=q
Answer:
a=q+f
Step-by-step explanation:
1. a-f=q
2. you need to do the opposite of -f which is +f to cancel it out
after that you need to do the +f to the q
Hope this helps
Using the literal equation a-f = q, the solution for a = p + q
What is literal equation?A literal equation are type of equations which have two or more unknown variables . A literal equation can be solved by adding or subtracting or multiplying or divide by same numbers to the both sides of the equation in order to solve the expression for the required variable.
For example if an given equation is x+ y =2 and we want to solve it for y
Then we will try to keep y on one side and take remaining terms to other side.⇒ y = x-2 is solution for y.
Given equation :
a- f = q
To solve for a, add f to both sides
⇒ a- f + f = q+ f
⇒ a = q + f
Solution for a is q +f.
