Stray from the side farthest to the left you will eithe go up or you kill either go over. If you go over to the left it's wrong. But if you go to the right it's correct but if the line is a negative and you end up going down the slop make sure to put your negligible sign.

I hope this helps you

length =width +1.25

Area =length ×width

320=w. (w+1.25)

w=18.625

l=19.875

In an arithmetic sequence, the nth term an is given by the formula An=a1+(n−1)d, where a1

Gnesinka [82]

Answer:

Step-by-step explanation:

We are given that in arithmetic sequence , the nth term $a_n$ is given by the formula

$A_n=a_1+(n-1)d$

Where $a_1=first term$

d=Common difference

In an geometric sequence, the nth term is given by

$a_n=a_1r^{n-1}$

Where r= Common ratio

1,4,7,10,..

We have to find 30th term.

$a_1=1,a_2=4,a_3=7,a_4=10$

$d=a_2-a_1=4-1=3$

$d=a_3-a_2=7-4=3$

$d=a_4-a_3=10-7=3$

$r_1=\frac{a_2}{a_1}=\frac{4}{1}=4$

$r_2=\frac{a_3}{a_2}=\frac{7}{4}$

$r_1\neq r_2$

Therefore, given sequence is an arithmetic sequence because the difference between consecutive terms is constant.

Substitute n=30 , d=3 a=1 in the given formula of arithmetic sequence

Then, we get

$a_{30}=1+(30-1)(3)=1+29(3)=1+87=88$

Hence, the 30th term of sequence is 88.

PLEASE HELP WILL MARK BRAINLIEST !!!!!!! 28 pts

Answer:

It costs $34 to buy a box of 64 markers.

Step-by-step explanation:

Check whether we are working with a direct proportion, in which case the comparison between the price and the number of markers would be the same.

$ 14 ÷ 24 = $0.58 and $ 7 ÷ 10 = $ 0.70

The prices differ, so they are not directly proportional.

The reason is that both prices include the price of the box, which is the same. This can be thought of as the constant.

If you were to draw a graph of price (on the y -axis) and number of markers (on the x -axis) you would get a straight line where the

y -intercept would be the price of the box and the slope would be the price of a marker. (rate of change of price)

Let's find the slope.

m = (y _2 − y _1 /x _2 − x _1)

m = ($14 −$ 7 /24− 10) = ($ 7 /14 markers) = $ 0.50 / marker

Therefore each marker costs

$ 0.50 or 50 c

the price of 64 markers is:

64 × 0.5 = $ 32.00 ← this is just the markers,

How much does the box cost? Consider

$ 7 for 10 markers at $ 0.50 each

$ 7 − 10 × $ 0.50 = $ 7 − $ 5 = $ 2

The box itself costs $2

The total cost of 64 markers in a box would be:

$ 2 + $ 32 = 34#
