Part one: Sequence and Series

ASHA 777 [7]

Answer:

- 57

Step-by-step explanation:

The n th term of an arithmetic sequence is

$a_{n}$ = a + (n - 1)d

where a is the first term and d the common difference

Here a = 13 and d = - 2.5, thus

$a_{29}$ = 13 + (28 × - 2.5) = 13 - 70 = - 57

Suppose Colby rolls the number cube 1000 times, about how many times can she expect to roll an odd number?

DiKsa [7]

Since there are 3 odd numbers ( 1, 3 and 5) and 3 even numbers ( 2, 4 and 6) in the cube ,

The chance of getting an odd number is 50/50 or 50%

So out of 1000 she will probably get 500 odd since 1000 × 0.5 (which is 50%) is 500

There are 4 boxes of 100 sheets of paper and some single sheets of paper in the closet . Choose all the numbers that show how ma

aleksandrvk [35]

406 and 411 because there is at least 400 sheets because of the 4 boxes of 100 so there would have to be more than 400 because of the loose sheets

The listed price of the video game was $34, but the price with tax came to $37.40. Find the percent sales tax.

Katarina [22]

Answer:

10%

Step-by-step explanation:

we want to find what % of 34 is 37.40

so, we will use the following equation:

$\frac{part}{whole} = \frac{percent}{100}$

for this scenario:

part = 37.40

whole = 34

percent = x

now plug in:

$\frac{37.40}{34} = \frac{x}{100}$ cross multiply

34x = (37.40)(100)

34x = 3740 divide both sides by 34

x = 110%

now we know that with tax, we paid 110% of the video game's price

110 - 100 = 10%

so the percent sales tax is 10%

<u>just to check... </u>

34 • 1.10 = $37.40

34 • .10 = 3.40

34 + 3.40 = 37.40

Tyler went to the supermarket to buy food for a food pantry. He has $36, and can carry up to 20 pounds of food in his backpack.

horrorfan [7]

Answer:

solutions: (2, 10), (4, 5)
non-solutions: all other points

Step-by-step explanation:

It can be useful to graph the inequalities related to Tyler's limits of money and weight.

1x +3y ≤ 36 . . . . . . the limit on the cost of the items Tyler can afford

1x +1.5y ≤ 20 . . . . . the limit on the weight of the items Tyler can carry

Then plotting the given points shows that only (2, 10) and (4, 5) are in the doubly-shaded area that is the solution space. The other points are not a solution.
