The fifth partial sum represents the sum of the first 5 terms in the sequence is equal to 2210.

The fifth partial sum represents the sum of the first 5 terms in the sequence.

The partial sum of a sequence gives the sum of the first n terms in the sequence.

Thus, the fifth partial sum represents the sum of the first 5 terms in the sequence.

The given geometric sequence :

$400, $420, $441, $463, and $486.

The fifth partial sum of the above sequence will be :

$400+ $420+ $441+$463+$486=$2210

Therefore, the fifth partial sum represents the sum of the first 5 terms in the sequence equal to 2210.

Answer:

He had 31 points in the first round.

Step-by-step explanation:

Answer:

39-8= 31

Step-by-step explanation:

let the first round be x

second round =8

first round + the second round = 39

therefore, x+8=39

collect like terms

x= 39-8= 31.

so the answer is 31

Hey there!

4 + 5x + 66 = x + 10

70 + 5x = x + 10

5x + 70 = x + 10

SUBTRACT x to BOTH SIDES

5x + 70 - x = x + 10 - x

5x + 70 - 1x = 1x + 10 - 1x

SIMPLIFY IT!
4x + 70 = 10

SUBTRACT 70 to BOTH SIDES

4x + 70 - 70 = 10 - 70

SIMPLIFY IT!
4x = -60

DIVIDE 4 to BOTH SIDES

4x/4 = -60/4

SIMPLIFY IT!
x = -60/4

x = -15

Therefore, your answer is: x = -15

Good luck on your assignment & enjoy your day!

Answer:

13 times?

Step-by-step explanation:

From 5 1/2 to 8 1/2 she needs to add 3 * 4 = 12 times since 1 paint = 4 pint

then she just needs to add 1 more to become 8 3/4

12 + 1 = 13

The order is 0 -> 1/4 -> 1/2 -> 3/4 -> 1

Answer:

See below

Step-by-step explanation:

1/3 (300000) = 100 000      80% of this = 80 000

2/5 (300000) = 120000    125% of this = 150 000    total so far = 230 000

Overall 10% profit would yield  300000(1.1) = 330 000

 the remaining land needs to sell for

    330 000 - 230000 =    100 000

The inequality that represents the possible combinations of candy bars and  lollipops that he can buy is given by:

[tex]0.45x + 0.25y \leq 28[/tex]

The total price can be no more than $28, hence:

[tex]T \leq 28[/tex]

Each candy bar costs $0.45 and each lollipop costs $0.25. x is the number of candy bars and y of lollipops. Hence, the total price is given by:

T = 0.45x + 0.25y.

Hence, the inequality that models the situation is:

[tex]0.45x + 0.25y \leq 28[/tex]

Answer:

1)  D. 8 2/6 hotdogs

2)  B. 2 1/5 cakes

Step-by-step explanation:

1) If she's dividing 50 hotdogs equally among 6 people, then you would divide 50 by 6 to find how many each person gets.
note: 50 ÷ 6 is the same as [tex]\frac{50}{6}[/tex].

[tex]\frac{50}{6}[/tex] =  [tex]8\frac{2}{6}[/tex]

6 can go into fifty 8 times, so there is a whole number of 8. There is 2/6 left over, so the final result is [tex]8\frac{2}{6}[/tex].

2) If Sako makes 11 cakes and wants to share it equally among 5 people, we can divide 11 by 5 to find how many each person gets.

[tex]\frac{11}{5} =2\frac{1}{5}[/tex]

5 can go into eleven 2 times, so there is a whole number of 2. There is 1/5 leftover, so the final result is [tex]2\frac{1}{5}[/tex].

Hence, the answers are D, and B.
