Answer:
AB=33, x=6.75
Step-by-step explanation:
In order to solve this equation, draw a line with three points labeled A, B, and C. Then fill out what you know with the given information being AB=4x+6 and BC=72+15, then AC=120. then follow these steps:
Write the following equation: 4x+6+72+15=120Add like terms: 4x+93=120Subtract 93 from both sides, isolating the variable (x): 4x=27Divide both sides by 4 to get x=6.75Now that we know that x=6.75, follow these steps:
Plug in x to the equation: 4(6.75)+6 to find the length of AB, and the answer would be 33.I hope this helps!!!

A conical tank (with vertex down) is 12 feet across the top and 18 feet deep. If water is flowing into the tank at a rate of 18 cubic feet per minute, find the rate of change of the depth of the water when the water is 10 feet deep.
Answer:
Step-by-step explanation:
Volume of a cone V = 1/3πR²h
r is the radius
h is the height
Given
dV/dt = 18ft³/min
h = 10ft
dimeter = 12ft
radius = 6ft
according to similar triangles
R = 6/10 h
R = 3/5 h
The volume becomes
V = 1/3πR²h
V = π/3(3h/5)²h
V = π/3 9h²h/25
V = 9h³π/75
dV/dt = dV/dh * dh/dt
dV/dt = 27h²π/75dh/dt
Substitute the given values
18 = 27(10)²π/75dh/dt
18 = 2700π/75dh/dt
18 = 36π dh/dt
dh/dt = 18/36π
dh/dt = 1/2π
dh/dt = 1/2(3.14)
dh/dt = 1/6.28
dh/dt = 0.1592ft/min
Robert spends $30.45 before tax at the book store. If the sales tax rate in his city is 7.25%, what is the total cost of his purchase?
The total cost of Robert's purchase is $32.657625.
Given that, Robert spends $30.45 before tax at the book store and the sales tax rate in his city is 7.25%.
We need to find the total cost of his purchase.
What is the sales tax?A sales tax is a consumption tax imposed by the government on the sale of goods and services.
The total cost = 30.45+7.25% of 30.45
=30.45 + 0.0725 × 30.45
=30.45 + 2.207625
=32.657625
Therefore, the total cost of Robert's purchase is $32.657625.

How do you solve 18x + 21y=204 and 6x + 14y=82
Answer:
x=9, y=2
Step-by-step explanation:
there are multiple ways to solve. I prefer lining both equations up so
18x + 21y =204
6x + 14y = 82
You can multiply 6x +14y =82 by -3 to get -18x + -42y = -246
then add both equations together to get y by itself. so you get
-21y=-42
y = 2
then substitute y back in to either equation and you'll get x=9

Rewrite in simplest terms: 9(2k – 3m) – 9m – 4(-3m - 3k)
Answer: 30k-24m
Step-by-step explanation:
so 9(2k-3m), there is an invisible multipulaction sign between the 9 and the parenthesis which means you have to multiply everything in there. 18k-27m.
Then -9m+12m+12k. Its a plus because two minuses make a positive.
18k-27m-9m+12m+12k. Now you put like terms together.
18+12k=30k, -27m-9m+12m= -24m
30k-24m

Answer:
R = ∞
I = (-∞, ∞)
Step-by-step explanation:
Use the ratio test:
lim(n→∞)│aₙ₊₁ / aₙ│
lim(n→∞)│[xⁿ⁺⁶ / (2(n+1)!)] / [xⁿ⁺⁵ / (2n!]│
lim(n→∞)│[xⁿ⁺⁶ / (2(n+1)!)] × (2n! / xⁿ⁺⁵)│
lim(n→∞)│x 2n! / (2(n+1)!)│
lim(n→∞)│n! / (n+1)!││x│
lim(n→∞) (1 / (n+1))│x│
0
The series converges if the limit is less than 1.
The limit is always less than 1, so the radius of convergence is infinite.
So the interval of convergence is (-∞, ∞).

Research suggests that red kangaroos have an average height of 63 in with a standard deviation of 4 in. What is the probability that a random sample of 45 kangaroos has an average of height that is greater than 70 inches.
Answer:
0.040
Step-by-step explanation:
We solve using z score
z = (x-μ)/σ,
where x is the raw score = 70 in
μ is the population mean = 63 in
σ is the population standard deviation = 4 in
z = 70 - 63 /4
z = 7/4
= 1.75
Probability value from Z-Table:
P(x<70) = 0.95994
P(x>70) = 1 - P(x<70)
= 0.040059
The probability that a random sample of 45 kangaroos has an average of height that is greater than 70 inches
is 0.040

Factored 16 out of the second term instead of 4
Did not apply the properties of exponents correctly
Factored 2 out of the first term instead of 4
Did not write the expression as division correctly
Answer:
Factored 16 out of the second term instead of 4
Did not apply the properties of exponents
Step-by-step explanation:
Given the expression :
8x^6 √200x^13 ÷ 2x^5√32x^7
STEP 1:
8x^6 √(25*4*2*(x^6)^2*x) ÷ 2x^5√16*2*(x^3)^2 *x
Step 2:
8*2*5*x^6√2x ÷ 2*4*x^5*x^3√2x[correct expression]
80x^12√2x ÷ 8x^8√2x
(80x^12√2x ) / (8x^8√2x)
10x^(12 - 8)
= 10x^4
The square root of 16 is 4 ;
Hence 4 should be factored out of the second term instead of 16
Answer: the mistake was in step 2 then: factored 16 out of the second term instead of 4
Step-by-step explanation:
Which amount is closest to Nathan's total costs after the 15% discount and including 6% sales tax? [Assume tax is applied after the discount is applied.]
Total price = $266.63 + $317.29+62.78=646.7
Discount = 15%
Discount amount = (15/100) x 646.7
=$97.005
Price after discount = $646.7 - $97.005
=$549.695
Sales tax = 6%
Sales tax amount =(6/100) x $549.695
=$32.9817
Total cost = Price after discount + sales tax amount
=$549.695 + $32.9817
=$582.6767
=$$582.68
