Mary pays $72 for sand. If the cost per pound is $0.45, how many pounds did she purchase?

Answer:

The answer should be 14/15.

Step-by-step explanation:

The answer is 14/15 because -2/5 and 4/3 with a common denominator turns into -6/15 and 20/15.

Then you add both of them together.

-6/15 + 20/15 = 14/15

Answer:

2.68 × [tex]10^{26}[/tex] Km³

Step-by-step explanation:

Using the given formula for volume V, then

V = [tex]\frac{4}{3}[/tex] π × (4 × [tex]10^{8}[/tex] )³

  = [tex]\frac{4}{3}[/tex] π × 4³ × ([tex]10^{8}[/tex] )³

 = [tex]\frac{4}{3}[/tex] π × 64 × [tex]10^{24}[/tex]

 = 268 × [tex]10^{24}[/tex]

 = 2.68 × 10² × [tex]10^{24}[/tex]

 = 2.68 × [tex]10^{26}[/tex] Km³

Answer:

it started off with 7 members

(read the whole explanation)

Step-by-step explanation:

Question: the chess club accepts 5 new members each week and it had 37 members after 6 weeks ? how many members per week and how many members did it start off with.

If the chess club accepts 5 each week and they had 6 members after 6 weeks you should multiply 5x6=30. We don't know when the chess club started.. it could be 6 or 7 weeks ago and I'm pretty sure we all know that 7x5=35. but it only says 6 weeks ago so the answer is 7,

hope this helps!!!!

Answer:

The image shows the points on a coordinate axis.

Step-by-step explanation:

The first point is [tex](-3,4)[/tex].

This means that the point on the [tex]x[/tex] axis is [tex]-3[/tex] and [tex]y[/tex] axis is [tex]4[/tex]. The point is in the second quadrant.

The second point is [tex](4,4)[/tex].

This means that the point on the [tex]x[/tex] axis is [tex]4[/tex] and [tex]y[/tex] axis is [tex]4[/tex]. The point is in the first quadrant.

The image shows the points on a coordinate axis.

Answer:

m=6

X1=4

Y1= -5

Y-Y1=m(X-X1)

Y-(-5)=6(X-4)

Y+5=6X-24

Y=6X-24-5

Y=6X-29

Answer:

20cm squared

Step-by-step explanation:

so the scale factor is 1:2 so you just double the area so,

10cm squared x 2 = 20cm squared

Answer:

D: 40

Step-by-step explanation:

If the scale factor is 1:2 it means that each side is twice as big after being scaled. However, because the area is width * height that means that the area of the scaled one gets doubled two times, so is actually 4x bigger. This means the answer is 4 * 10 = 40 square cm

Answer:

On each team there is the same number of teammates, the answer is D. 8 (9 + 5).

Step-by-step explanation:

If you add up the amount of teammates then multiply that by the number of teams.

Therefore, D. 8 (9 + 5) is the answer.

Answer:

Answer:2+n

Step-by-step explanation:

1. distribute parentheses

=-(-2)-(-n)

2.apply minus-plus rules

=2+n

The  base   is a number that is multiplied. The number that indicates how many times this number is used as a factor is the  exponent  

For example, the number 2^3 expands out to 2*2*2. We have three copies of the base '2' being multiplied.

Another example: 5^2 = 5*5.

Answer:

The "Factor" is a number that is multiplied. The number that indicates how many times this number is used as a factor is the "Exponent".

Step-by-step explanation:

Example: 7 • 7 can be written as 72, 7 is the base and 2 is the exponent. The exponent 2 means there are two factors.

Answer:

10 i guess

cause

8*3=24

3*10=30

Step-by-step explanation:

Since the scale factor of the large to small triangle is 3 : 1, the side lengths of the small triangle are 1/3 of the big triangle side lengths. (such as 8 compared to 24)

Therefore 3x = 30 and x = 10.

Answer:

3,000 women

Step-by-step explanation:

6  :  5        

m    w

so if 6 represents men and 5 represents women, then

3,600/6=600

so

5x600=3,000

so your answer would be 3,000

Answer:

The answer is t.

Step-by-step explanation:

We need to find the sum of opposite of - 10t and t - 10t.

Opposite of -10t = 10 t

So,

10t + (t-10t)

Grouping the numbers,

(10t+(-10t)) + t

= 0 + t

= t

Hence, the answer is t.

Answer:

3 miles per hour.

Step-by-step explanation:

To get his walking rate in miles per hour, we multiply 1/5 by its reciprocal, 5/1. We also multiply 6/10 by 5/1. This gets us 30/10 of a mile in an hour. We can simplify 30/10 to 3. This means he walks at 3 miles per hour.
