a)

Mean = 17 + 19 + 25 / 3
Mean = 61/3
Mean = 20.3

b)

Mean = 38 + 36 + 34 + 32 / 4
Mean = 140/4
Mean = 35

c)

Mean = 8.3 + 2.6 + 7.4 + 1.8 + 9.5 / 5
Mean = 29.6/5
Mean = 5.92

d)

Mean = -5 + 2 - 1 + 0 - 9 + 4 / 6
Mean = -9/6
Mean = -1.5

Stephanie needs to cover her yard with 4103/4ft2 of soil she has enough for 125 ft2 in one bag and 65 ft 2 in another bag how mu

Evgen [1.6K]

Answer:

Stephanie requires 835.75 square feet more amount of soil to cover her yard.

Step-by-step explanation:

Given:

Total square feet of yard she need to cover with soil = $\frac{4103}{4}\ ft^2$

$\frac{4103}{4}\ ft^2$ can be rewritten as 1025.75 square feet.

Total square feet of yard she need to cover with soil = $1025.75\ ft^2$

Amount of soil in one bag = $125\ ft^2$

Amount of soil in other bag = $65\ ft^2$

Total Amount of soil she has is equal to sum of Amount of soil in one bag and Amount of soil in other bag.

Framing the equation we get;

Total Amount of soil she has= $125+65 = 190\ ft^2$

Now We need to find the Amount of soil she required more to cover the yard.

Amount of soil she required more is equal to difference of Total Amount of soil she has and Total square feet of yard she need to cover with soil.

Framing the equation we get;

Amount of soil she required more = $1025.75-190= 835.75\ ft^2$

Hence Stephanie requires 835.75 square feet more amount of soil to cover her yard.

two triangles are similar. the sides in order of smallest to largest of the smaller triangle are 3.5, y, and x. the sides in ord

nataly862011 [7]

Since the triangles are similar, the ratio of each side in one triangle to
the corresponding side in the other one is always the same number.
We know what one pair of sides is ... 3.5 and 7 ... so we know that
each side in the first triangle is 1/2 as long as the corresponding side
in the other one.

So we can say with assurance that ...

y = 1/2 (x + 4)
and
      x = 1/2 (3y) .

That's all the intelligence required for this problem. The rest is just algebra,
and I should not need to go through all the routine misery for you here.

When you solve this pair of equations slowly, carefully, and accurately,
you'll find that the sides of the triangles are ...

   3.5,   8, 12
and
   7, 16, 24 .

A shirt is on sale for $42. If this is of the original price of the shirt, what was the original price of the shirt?

bixtya [17]

Answer:

C. $70.00

Step-by-step explanation:

First convert the discount rate of 60% into a decimal (0.6)

Remember that the original price(x) times the discount rate(0.6) is the sale price(42).

0.6x=42

divide both sides by 0.6 to get

x=70

The original price was $70.00

please help i missed this class and i’m a little confused (question is in the pic)please tell me how to solve it

Elena L [17]

So you have to isolate h to find what h is equal to. You do this by doing the opposite of what is being done to H, so instead of dividing by 7 you multiply the other side by 7.
The answer is 0.
