Answer 1

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]

Natalia is moving into a new house. All together, her furniture weighs 2,896 pounds. If it takes 2 trucks to carry all of Natalia's furniture, what is the average weight load on each truck?

Answers

Answer:

1448 Pounds per truck

Step-by-step explanation:

Divide 2896 by 2

If you haven't learned long division yet, try breaking up the number and dividing it by 2 like this:

2000/2=1000

800/2=400

90/2=45

6/2=3

Then, add them up and solve from there: 1000+400+45+3=1400+48=1448

Answer:

1448

Step-by-step explanation:

2,896/2 = 1448

Your friend finds the value of 8⁴. 8⁴ = 8x4 = 32 Is your friend correct? Explain

Answers

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.

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:

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:

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.

Giovanni can read 210 words per minute. If there are approximately 540 words on a page, about how many pages can he read in 3 hours? Round your answer to the nearest whole number.

462 pages
122 pages
233 pages
70 pages

Answers

It would be 70 pages because 210 divided by 3 is 70

She can read 70 pages in 3 hours.

What is proportion?

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

The relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.

We are Given:

Giovanni can read 210 words per minute and, books contain 540 pages

So, she can read the portion of book

=210/540

= 21/54 per minutes

= 21/54 x 60

= 23.3 pages in one hour

and in 3 hours she can read

= 23.3 x 3

= 70 pages in 3 hours

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

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

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
