Answer:
[tex]a_n=-8+(n-1)-7[/tex]
Step-by-step explanation:
General arithmetic sequence formula: [tex]a_n=a_1+(n-1)d[/tex]
where [tex]a_1[/tex] = first term, and d = common difference.
The first term is -8
And the common difference appears to be - 7 as 7 is subtracted to get to the next term. Ex. -8 - 7 = -15, -15 - 7 = - 22 and so on.
To get the explicit formula of the sequence we simply plug in the values of a1 and d the general arithmetic sequence formula
General formula: [tex]a_n=a_1+(n-1)d[/tex]
We have [tex]a_1=-8[/tex] and d = -7
So the formula to find the nth term would be
[tex]a_n=-8+(n-1)-7[/tex]

What is the solution to this equation?
−6(x+7)=−30
Enter your answer in the box.
Answers
Answer:
x = -2
Step-by-step explanation:
-6(x + 7) = -30
distribute the -6
-6 * x = -6x and -6 * 7 = -42
-6x - 42 = -30
add 42 to both sides
-6x = 12
divide both sides by -6
-6x/-6 = x and 12/-6 = -2
we're left with x = -2

A tire from Karens car is shown below Which is closest to the distance traveled, in feet, after 3 full rotations of the tire? use pi= 22/7
Answers
Answer:
264 inches
Step-by-step explanation:
Circumference = pi x diameter
28 x 22/7 = 88 (in)
88 x 3 = 264 (in)
The closest distance traveled by Karen's car is, 18.86 feet.
What is Circle?The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.
We know that;
One rotation of the tire is equal to the circumference of the tire.
And, The formula for circumference of a circle (remember that a tire is shaped as a circle) = πd
where, π = 22/7
d = diameter
Here, The size of one revolution = 2 x 22/7
= 44/7 feet
Hence, The distance covered in one rotation of the tire is 44/7 feet
So, The distance covered in 3 rotations = (44/7) x 3
= 18.86 feet

Sarah wanted to buy a TV. She had $390 in her pocket. The TV she wanted was $415; however she had a 10% off coupon. The sales tax is 6%. Does she have enough money to purchase the TV?
Answers
Answer: Sarah does not have enough money to purchase the TV.
Explanation: The total price is $395.91.
Answer:
No
Step-by-step explanation:
10% of 415
= 1/10 of 415
= 1/10 * 415
= $41.5
415 - 41.5 = $ 373.5
6% of 415
= 6% * 415
= $24.9
∴ $373.5 + $24.9 = $398.4
∴ Sarah cannot buy the TV as she is $ 8.4 short.

Question: 5/12 − 2/5= 1/60
A. The answer 1/60 is not reasonable because 5/12 is closer to 1 than to 1/2, and 2/5 is closer to 0 than to 1/2, making the difference close to 1/2.
B. The answer 1/60 is not reasonable because 5/12 is closer to 1/2 than to 1, and 2/5 is closer to 0 than to 1/2, making the difference close to 1/2.
C. The answer 1/60 is reasonable because both fractions are closer to 1/2 than they are to 0, making the difference close to 0.
D. The answer 1/60 is reasonable because both fractions are closer to 1 than they are to 1/2, making the difference close to 0.
Answers
Answer:
C
Step-by-step explanation:
It is reasonable: the answer is both reasonable and correct because 5/12 - 2/5 = 1/60. This is because using cross multiply, 5 x 5/12 = 25/60, 12 x 2/5 = 24/60. 25/60 - 24/60 = 1/60.
Both are closer to half: half out of 12 would be 6/12 and 0 would be 0/12, so 5/12 is closer to half because 5/12 is closer to 6/12 than 0/12. Half out of 5 would be 2.5/5 and 0 would be 0/5, so 2/5 is closer to half because 2/5 is closer to 2.5/5 than 0/5.
The difference is close to 0: 1/60 is very close to 0. It's only worth 0.016.

Max is scuba diving at an elevation of −64.5 feet when his friend signals to come higher. Max makes two ascents, each an equal distance, to reach an elevation of −21.4 feet, where his friend is located. What was Max's elevation after his first ascent? Enter your answer as a decimal in the box.
Answers
Answer:
-42.95ft
Step-by-step explanation:
First, find the change in elevation between where Max starts and where his friends are:
-21.4ft-(-64.5ft)=43.1ft
Since we're told that he makes two equidistant ascents, we know that each ascent would be equal to:
43.1ft/2=21.55ft
Now we take the height that he started at and add the height that he would gain in his first ascent
-64.5ft+21.55ft=42.95ft

Ramiro is 3/10 as tall as the flagpole. The flagpole is 5/9 as tall as the nearby tree. The tree is 32 2/5 feet tall. How tall is Ramiro?
Answers
Answer:
5.4 feet
Step-by-step explanation:
Start with the flagpole. It is 5/9 of 32 2/5.
32 2/5 = 162/5.
5/9 * 162/5 = 162/9.
Ramiro is 3/10 as tall as 162/9.
3/10 * 162/9 = 27/5, or 5.4 feet tall
His height is 5.4 f

I would say my friend is correct. I think this because when doing function tables, i would often say x2, x5, etc. This would mean that it would be X x 2, and X x 5. If you replace the "x" and turn it into 8, than I would think it would mean the same thing. So, yes. My friend is correct.
