A new sports store recently opened downtown that specializes in baseball cards. Delmar has over 200 baseball cards in his collec

tion and plans to see how much money he can get for some of his cards. After looking through Delmar's cards, the dealer tells Delmar that 15 of the cards can be sold for $23.50 each, and 27 of the cards can be sold for $32.50 each. The rest of the cards can be sold somewhere in the range of $3 to $10 each. If Delmar sells all of the cards worth $23.50 and $32.50, how much money would Delmar receive?

Answer: 15 of the cards can be sold for $23.50 each, and 27 of the cards can be sold for $32.50 each. This is all he wants to sell so the answer would be (23.5 x 15) + (27 x 32.5)

$1230

Y is the midpoint of WZ. X is the midpoint of WY.XY = 14. What is<br> the length of wz
Dimas [21]

Answer:

56

Step-by-step explanation:

First, I drew picture of a line containing points W and Z.

Next, I added a midpoint between W and Z and labelled it Y.

Next, I added a midpoint between W and Y and labelled it X.

It is given that XY = 14, so that means WX is also 14 (because X is the midpoint, these two distances have to the be the same)

Now I know WY is 28, which means YZ is also 28.

So WZ has to be 56.

<h3>Answer: Choice D</h3>

If you have a single straight vertical line cross the curve at more than one point, then you do not have a function. In other words, if an x input leads to multiple outputs, then you don't have a function.

Find the first five terms of the sequence in which a1 = –10 and an = 4an – 1 + 7, if n ≥ 2.
Sholpan [36]

The first five terms of the sequence are -10, -33, -125, -493, -1965

Explanation:

The given expression is a_n=4a_{n-1}+7

And a_1=-10 is the first term of the sequence.

We need to determine the first five terms of the sequence.

<u>Second term:</u>

Substituting n = 2 in the expression a_n=4a_{n-1}+7, we have,

a_2=4a_{2-1}+7

a_2=4a_1+7

a_2=4(-10)+7

a_2=-40+7=-33

Thus, the second term is -33

<u>Third term:</u>

Substituting n = 3 in the expression a_n=4a_{n-1}+7, we have,

a_3=4a_2+7

a_3=4(-33)+7

a_3=132+7=-125

Thus, the third term is -125

<u>Fourth term</u><u>:</u>

Substituting n = 4 in the expression a_n=4a_{n-1}+7, we have,

a_4=4a_3+7

a_4=4(-125)+7

a_4=-500+7=-493

Thus, the fourth term is -493

<u>Fifth term</u>:

Substituting n = 5 in the expression a_n=4a_{n-1}+7, we have,

a_5=4a_4+7

a_5=4(-493)+7

a_5=-1972+7=-1965

Thus, the fifth term is -1965

Hence, the first five terms of the sequence are -10, -33, -125, -493, -1965

4736 divided by 100 for math
damaskus [11]
If you divided 4.736 ÷ 100 you have to find the times 100 is in 473, is 4 times, then you have to find how many times is 100 in 736, is 7 times, then you have 36 but this is not a entire number then you add a 0, 100 is 3 times in 360, now you have a 6, you add two zeros, 100 is six times in 600. 47,36 is the answer.
