Step-by-step explanation:
Answer:
8hours=8/3×12=32cars
Step-by-step explanation:
Part 1: Explain what the following variables represent and how changing each one affects the monthly payment amount: P, i, and t.
Part 2: Explain how changing each variable (P, i, and t) affects the total cost of principal and interest over the life of the loan.
Answer:
Part 1 and 2: P represents principle, or the original cost of the mortgage. i represents the annualinterest rate (r/n), and t represents time. When you change the time it affects monthlypayments because theres either more or less time to pay off the mortgage. Having a longertime to pay off means you'll have lower monthly payments. When the interest rateincreases, the monthly payment increases. This is because the higher the interest rate, themore interest you're paying. Changing the principle means you either have more or lessmoney to pay off.P2: Increasing i will increase the total cost since more interest will be charged. Increasingtime means there's more periods for interest to gather so the total cost will increase.Shortening the time will decrease the total cost because there will be less time for interestto accumulate.

Karen purchased a prepaid phone card for $15. Long-distance calls cost 19 cents a minute using this card. Karen used her card only once to make a long-distance call. If the remaining credit on her card is $12.91, how many minutes did her call last?
Answer:
I am pretty sure the answer is 11 minutes and the cost was $2.09
Step-by-step explanation:
Ihope this helps you:)
Step-by-step explanation:
Ok so we start with $15 now the remaining amount is $12.91, so let's substract
15.00 - 12.91 = 2.09
Alright now I must work with this number, since every minute used on the call is 19 cents, i must divide 2.09 to see how many 19 cents fit into this number
2.09 / 0.19 = 11
So she lasted talking or in this call 11 minutes....
I hope this helps!
A flagpole that is 28 feet tall casts a 15-foot shadow. At the same time, a nearby tree casts a 21 foot shadow. Find the height of the tree.
Round to the nearest tenth.
Answer:
7.5 ft tall
Step-by-step explanation:
We can find the height of the tree if you provide the actual length of the trees shadow.
Not really sure what a "toilet for a shadow" means.
Example: If the tree cast a shadow that was 4 feet long we would use a ratio:
Height/shadow = Height/Shadow
28/15 = x/4 cross multiply
15x = 4(28)
x = 4(28)/15 ≅ 7.47 ft
Rounding I would call the tree 7.5 ft tall
Hope this helps.
Answer:
39.2 feet
Step-by-step explanation:
In case of flagpole:
[tex] tan \theta = \frac {28}{15}..... (1)[/tex]
Since, a nearby tree casts a 21 foot shadow at the same time. So the angle formed will be equal.
Let the height of the tree be x feet.
Therefore,
[tex] tan \theta = \frac {x}{21}.....(2)[/tex]
From equations (1) & (2)
[tex] \frac {28}{15} = \frac {x}{21}.....(2)\\\\
x = \frac{28\times {21} }{{15} }\\\\
x = \frac{588}{{15} }\\\\
x = 39.2 \\\\

Find x:
[tex]S=\frac{1}{sin2x}+\frac{1}{sin4x}+\frac{1}{sin8x}+...+\frac{1}{sin2^{n}x }[/tex]
Answer:
cotx - cot2ⁿxStep-by-step explanation:
Note: finding the sum not xFirst rewrite the first term as:
1/sin2x = sinx / (sinxsin2x) = sin(2x-x) / (sinxsin2x) =(sin2xcosx - cosxsinx) / (sinxsin2x) = (sin2xcosx)/(sinxsin2x) - (cos2xsinx)/(sinxsin2x) = cosx/sinx - cos2x/sin2x = cotx - cot2xNow the sum is:
S = cotx - cot2x + cot2x - cot4x +... + cot2ⁿ⁻²x - cot2ⁿx =cotx - cot2ⁿxIn a trivia game your team has -6 points. The other team has 15 points. What is the difference in points between the two teams?

180 miles in 4 hours =
miles per hour
Answer:
= 45 miles per hour
Step-by-step explanation:
First, we want a unit rate where 1 is in the denominator.
So we divide,
180 miles/ 4 hours both ÷ by 4
= 45 miles/ 1 hour
= 45 miles/ hour
= 45 miles per hour

Step-by-step explanation:
S is equal to Q
Q= 48.5
there are two angels (S,Q). They equal 48.5
so 48.5x2= 97
all angels together (QRSP) equals 360
you can take the 97 and subtract it from the 360 =263
divide 263 to get the angels for P and R
S= 48.5
Q=48.5
R=131.5
P=131.5
