1st one . . . . . 1
2nd one . . . . . 3
3rd one . . . . . 5
4th one . . . . . 7
5th one . . . . . 9
.
.
9th one . . . . . 17

It looks to me like the 'n'th odd number is always (2n - 1) .

In that case, the 200th odd number is (2x200 - 1) = 399 .

I'll let you check it out and see if that's correct.

Answer:

3000m

42.875 m/cm/mm/km/in/miles³ etc. (don't know what measurement you need).

Step-by-step explanation:

1 km = 1000m

Volume of a cube is V=a³ thus 3.5³ = 42.875³

The vertex of a parabola that opens downward is at (0, 4). The vertex of a second parabola is at (0, –4). If the parabolas inter

erma4kov [3.2K]

Many statements can be true about those parabolas, so you need to include the list of choices.

This is the list of answer choices that I found for this same question:

A. The second parabola opens downward.
B. The second parabola opens upward.
C. The points of intersection are on the x-axis.
D. The points of intersection are of equal distance from the y-axis.

While A, B or C may be or may not be true, D has to be true.

D. has to be true because the symetry axis of both parabolas is x = 0, so the intersection points will be necesarily to the same distance of the x-axis and the y-axis.

Answer: 
The points of intersection are of equal distance from the y-axis.

bearhunter [10]

Answer:

The inequality to determine the number of days, $s$ , Darcie can skip crocheting and still meet her goal is:

$s\leq 15$

Thus, Darcie can skip a maximum of 15 days.

Step-by-step explanation:

Question

Darcie wants to crochet a minimum of 3 blankets to donate to a homeless shelter. Darcie crochets at a rate of 1/15 of a blanket per day. She has 60 days until when she wants to donate the blankets, but she also wants to skip crocheting some days so she can volunteer in other ways. Write an inequality to determine the number of days, s, Darcie can skip crocheting and still meet her goal.

Given:

Darcie has a target to crochet a minimum of 3 blankets.

Rate at which Darcie crochets = $\frac{1}{15}$ of a blanket per day.
