Answer:
12 months
Step-by-step explanation:
Set up a formula; 75 + 15x = 255
Now, solve for x, which is number of months.
subtract 75 from both sides.
15x = 180
divide both sides by 15.
x = 12
x is equal to 12 - she would have had to have the subscription for 12 months to spend 255$.
Simplify: (6q^3)^2
And tell me step by step
Answer:
36q^6
Step-by-step explanation:
First, use the distributive property and so you would have 6²q^6. Then you would solve 6² which is 36. Lastly, the answer will be 36q^6. Explaining is my weakness and I tried to help.

Patty buys a new car and gets it appraised every few years. After owning the car for 3 years, its value is $15,000. After owning the car for 5 years, its value is $9,000.
If Patty gets her car appraised after owning it for 6 years, what will the car's value be in this indirect variation situation?
A. $7,500
B. $2,500
C. $6,000
D. $4,000
Answer:
c) 6000
Step-by-step explanation:
the car's value would be $6000 because in two years the car decrased by $6000. Divide that by 2, and get $3000. That's how much it decreases in one year. $9000-$3000=$6000
btw I can't help it the car's original value was $24,000

Charmaine drives a truck for a soft drink company. Her truck is filled with 20 ounce cans and 80 ounce bottles. Let x be the number of 20 ounce cans the truck is carrying, and let y be the number of 80 ounce bottles.The truck must be carrying at most 48,000ounce). Using the values and variables given, write an inequality describing this
9514 1404 393
Answer:
20x +80y ≤ 48000
Step-by-step explanation:
If x is the number of 20-ounce cans, then the number of ounces in the cans is 20x.
If y is the number of 80-ounce bottles, then the number of ounces in the bottles is 80y.
"At most 48,000 ounces" means the total of ounces of cans and ounces of bottles must be less than or equal to 48000.
20x +80y ≤ 48000

Outside temperature over a day can be modeled as a sinusoidal function. Suppose you know the temperature is 80 degrees at midnight and the high and low temperature during the day are 89 and 71 degrees, respectively. Assuming t is the number of hours since midnight, find an equation for the temperature, D, in terms of t.
Answer:
The equation is given by:
[tex]D(t) = 80 + 9\sin{0.2618t}[/tex]
Step-by-step explanation:
Sine function:
Has the following format:
[tex]y = A\sin{bx}[/tex]
In which A is the amplitude and [tex]\frac{2\pi}{b}[/tex] is the period.
Suppose you know the temperature is 80 degrees at midnight and the high and low temperature during the day are 89 and 71 degrees
This means that the amplitude of the sinusoidal variation function is 89 - 80 = 80 - 71 = 9. This means that [tex]A = 9[/tex]
During a 24-hour day, which means that the period is 24. So
[tex]\frac{2\pi}{b} = 24[/tex]
[tex]24b = 2\pi[/tex]
[tex]b = \frac{2\pi}{24}[/tex]
[tex]b = 0.2618[/tex]
So the variation is:
[tex]V(t) = 9\sin{0.2618t}[/tex]
Assuming t is the number of hours since midnight, find an equation for the temperature, D, in terms of t.
Initial temperature of 80, so:
[tex]D(t) = 80 + V(t) = 80 + 9\sin{0.2618t}[/tex]

at noon the temperature in successor Michigan was 82°F by midnight the temperature had fallen to 66°F what was the change in temperature over the 12 hour period
Answer:
The change in temperature was of -16ºF, that is, a decrease of 16ºF.
Step-by-step explanation:
At noon, the temperature was of 82°F.
By midnight the temperature had fallen to 66°F.
Change:
Final value subtracted by initial value, so
66ºF - 82ºF = -16ºF
The change in temperature was of -16ºF, that is, a decrease of 16ºF.

Can someone please help me
Answer:
A. 1200
Step-by-step explanation:
Speed in meter per minute
= (216*1000)/(3*60)
= 216000/180
= 1200
Answer:
A. 1200
Step-by-step explanation:
Distance travelled (d)
= 216 km
= 216000 m
time taken (t)
= 3 hours
= 3 * 60
= 180 min
Speed (s)
= d / t
= 216000/180
= 1200 m / min
The speed of the car is 1200 metres per minute.

Terms/CoefficientsStep-by-step explanation:
Step 1: Define
5(2x - 8) + 15 = -15
Step 2: Solve for x
[Subtraction Property of Equality] Subtract 15 on both sides: 5(2x - 8) = -30[Division Property of Equality] Divide 5 on both sides: 2x - 8 = -6[Addition Property of Equality] Add 8 on both sides: 2x = 2[Division Property of Equality] Divide 2 on both sides: x = 1Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 5(2(1) - 8) + 15 = -15(Parenthesis) Multiply: 5(2 - 8) + 15 = -15(Parenthesis) Subtract: 5(-6) + 15 = -15Multiply: -30 + 15 = -15Add: -15 = -15Here we see that -15 does indeed equal -15.
∴ x = 1 is the solution to the equation.
Answer: x=1
Step-by-step explanation:
Let's solve your equation step-by-step.
5(2x−8)+15=−15
Step 1: Simplify both sides of the equation.
5(2x−8)+15=−15
(5)(2x)+(5)(−8)+15=−15(Distribute)
10x+−40+15=−15
(10x)+(−40+15)=−15(Combine Like Terms)
10x+−25=−15
10x−25=−15
Step 2: Add 25 to both sides.
10x−25+25=−15+25
10x=10
Step 3: Divide both sides by 10.
10x/10=10/10

Answer:
It takes Garret 15 mins to remove one ft of hem.
(cause 4" for 5 mins x 3 = 12" for 15 mins)
He should multiply the number of minutes by 5 to determine the number of minutes to remove 5 ft of hem.
(15 x 5 = 75)
It will take 75 mins to remove 5 ft of hem.

What is the leading coefficient of the polynomial f(c) defined below? need help asap!
Answer: 7
Step-by-step explanation:
The leading coefficient is the number before the term with the highest power in your polynomial. The coefficient is just a number or constant that is before a variable in your expression.
In this case, the highest degree in this polynomial is five. If we look at the coefficient of that term, we see that it is seven.
