Answer:
2a²
Step-by-step explanation:
Pair 'like' terms with 'like' terms, ie numbers go with numbers, and 'a's go with 'a's.
Lets deal with the top of the fraction first:
4ax3a³
Rearrange it so you have numbers beside numbers and 'a's beside 'a's:
(4x3)x(axa³)
12x(a⁴) (because nᵃxnᵇ=nᵃ⁺ᵇ)
12a⁴
Now, instead of (4ax3a³)/6a², we have 12a⁴/6a²
First divide the numbers: 12/6 =2
Now divide the 'a' parts: a⁴/a²=a² (because nᵃ/nᵇ=nᵃ⁻ᵇ)
Now we have 2a²

Rich also has £400 pounds invest 3% compound interest . How many years does he need to invest the money to get at least £475
Answers
Answer: 6 years
Step-by-step explanation:
Formula to calculate compound amount: [tex]A=P(1+r)^t[/tex], where P= Principal , r=rate of interest, t= time
Given: P = £400, r = 3% = 0.03 , A= 475
Required equation: [tex]400(1+0.03)^t\geq475[/tex]
[tex]400(1.03)^t\geq475\\\\\Rightarrow\ (1.03)^t\geq\dfrac{475}{400}\\\\\Rightarrow\ (1.03)^t\geq1.1875[/tex]
Taking log on both sides , we get
[tex]t \log 1.03\geq\log1.1875\\\\\Rightarrow\ t(0.0128372)\geq(0.0746336)\\\\\Rightarrow\ t\geq\dfrac{0.0746336}{0.0128372}=5.81385\approx6[/tex]
Hence, he needs to invest the money for 6 years to get atleast £475.

Martha rented a sedan at a cost of $21.25 a day for three days. She drove 980 miles at 25 cents a mile. Gas cost $63.45 what was the cost per mile
Answers
Answer:
38 cents per mile
Step-by-step explanation:
Let us first calculate the total expenditure by Martha
= 21.25*3= $ 63.75
Cost of gas =$ 63.45
Therefore cost per mile = 127.2/980= 0.1297+0.25= $0.3797 or 38 cents per mile

Answers
Answer:
because 3 spheres is inside the cylinder and they are placed close together
=> The height of the cylinder is 3 times the diameter
=> the height is 18cm
the volume of the cylinder is 3,14.18.(6/2)² = 508,68
because 3 spheres have the same diameter
=> the volume of 3 spheres is 4.3,14.3³ = 339,12
=> the volume of the cylinder that is left empty is 508,68 - 339,12 = 169,56
Step-by-step explanation:
Answer:
The answer is 508,68
Step-by-step explanation:
Since the volume of the cylinder is equal to the area of the permanent base multiplied in the height
Since the radius of the base is equal to 3 and since the area of its cylinder is equal to
[tex]314 \times 3 \times 3 = 28.26[/tex]
When the height equal to 18
Then the volume equal to
[tex]28.26 \times 18 = 508.68[/tex]

f(4) is just asking what the y value is when x=4 which is 1
f(-3) = -4
This has no minimum or maximum because the range is all real numbers (the y value goes to infintiy and negative infinity)
f(3)=6
f(0)= 3

Brad has $75 in his savings account and adds $25 every month he doesn't make any withdrawals from the account which inequality shows the number of months it would take Brad to save at least $200
Answers
The inequality representing the problem will be x+3 ≥ 8
What is inequality?A relationship between two expressions or values that are not equal to each other is called inequality.
Given that, Brad has $75 in his savings account and adds $25 every month he doesn't make any withdrawals from the account, and saves at least $200.
Let the number of months be x,
75 + 25x ≥ 200
25(3+x) ≥ 200
x+3 ≥ 8
Hence, The inequality is x+3 ≥ 8

Answer:
31.4 in
Step-by-step explanation:
the formula for circumference is 2*[tex]\pi[/tex]*radius. Since the diameter (which is the radius multiplied by 2) is labeled we can divide 10 by 2 to get the radius. 10/2 is 5. Since pi is an infinite number, we round it to 3.14. Then, plug in the numbers. The expression will be 2*3.14*5. 2* = 10 and 10 * 3.14 you can just move the decimal so the answer is 31.4.

Elise had a credit card balance of -$120. She
made a payment of $70 this month. Write and
then evaluate a SUBTRACTION expression to
find her new credit card balance.
Answers
Answer:
15.50+n=325.00
Step-by-step explanation:
15.50+what she had in the bank already = what she has now
Step-by-step explanation:
Elise's new credit card balance is $-50.
Elise's credit card balance is negative. This means that she has withdrawn more money than she has deposited. Elsie thus owes the bank $-120. If she paid $70, the amount she owes would be reduced by $70.
Elise's new credit card balance = credit card balance + payment made
$-120 + $70 = $-50
