No. 1 is actually correct. Nice work!

In No. 2, it's much easier to tackle the problem sentence by sentence. In the first sentence, we are given that Val has 6 yards of fabric. In the next sentence, we are given that she uses 1/3 of that piece of fabric to make a shirt. Let's calculate how much she has left now.

6 x (1/3) = 2
Val used up 2 yards, meaning she has 4 yards left.

The next sentence indicates that she uses 3/8 of what she has left, which is 4 yards of fabric. We can apply the same method as the first step.

3/8 x 4 = 3/2

She used up 1.5 yards to make a shirt for her sister, meaning she has 2.5 yards left.

Final Answer: 2.5 yards of fabric

Calculate the volume of a rectangular prism with a length of 4.4 cm, a width of 3.1 cm, and a height of 6.3 cm. (As before, you

maria [59]

Answer:

85.932 cm³

Step-by-step explanation:

The volume of rectangular prism is obtained as the product of its length (l) by its width (w) and by its height (h):

$V=l*w*h$

The volume of a prism with a length of 4.4 cm, a width of 3.1 cm, and a height of 6.3 cm is:

$V=4.4*3.1*6.3\\V=85.932\ cm^3$

The volume of this prism is 85.932 cm³.

A retailer has determined that the cost C of

adelina 88 [10]

A. The expression given in the question is

c = 6x + (900000/x)
c = (6x^ +900000)/x
I hope that this is the expression that you were looking for.

b. When x = 240, then

c = [6 * (240)^2 + 900000]/ 240
= (6 * 57600) + 900000/240
= (345600 + 900000)/240
= 5190

From the above deduction, it can be concluded that the cost of ordering and storing is 5190. I hope the procedure is clear enough for you to understand.

out of a group of zebras 6/5 times the square root of the number of zebras are playing on the shore of the tank remaining six ar

MatroZZZ [7]

Answer:

Step-by-step explanation:

(6/5)√x = x - 6

(36/25)x = x² - 12x + 36

0 = x² - 13.44x + 36

x = (13.44 ± √(13.44² - 4(1)(36))) / (2(1))

x = (13.44 ± 6.052569702...) / 2

x = 3.69371... zebras

x = 9.74628... zebras

In either case we have some odd fractions of zebras hanging around. This makes me highly suspect that the question is misreported

What two numbers multiple to -3468 and adds to 24

Alex777 [14]

Answer:

72.1 and -48.1

Step-by-step explanation:

I set up the equations x + y = 24 and x*y=-3468. Then I substituted for y and used the quadratic formula to come to two numbers rounded to about 72.1 and -48.1. Hope that helps :)

Jerry planted a pine tree that was 5 feet tall and a maple tree that was 10 feet tall. The pine tree grew 3 feet taller per year

stich3 [128]

The initial length of the pine tree=5 feet.

Groth rate of pine tree =3 feet/year.

The initial length of the pine tree =10 feet.

Groth rate of the maple tree =2 feet/year.

After x years, the height of the pine tree= 5+3x feet and

after x years, the height of the maple tree= 10+2x feet.

The inequality for which, after x year, the pine tree is taller than the maple tree is

$5+3x>10+2x$
