Charlie makes 8 kilograms of dough every hour. If he works for 4 hours preparing the dough, then Charlie would have prepared 32 kilograms of dough.

So you have 8 kilograms every hour.

8:1

There are 4 hours that Charlie works on preparing dough. That would be 1 times 4. What you do to one side, you must do to the other.

8 times 4 is 32.

So Charlie has the ratio of 32:4.

Charlie makes 32 kilograms.

The point-slope form:

$y-y_1=m(x-x_1)$

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points A(-2, 6) and B(2, -2). Substitute:

$m=\dfrac{-2-6}{2-(-2)}=\dfrac{-8}{4}=-2\\\\y-6=-2(x-(-2))\\\\\boxed{y-6=-2(x+2)}\to\boxed{(B)}$

The Management of a private investment club has a fund of $200,000 earmarked for investment in stocks. To arrive at an acceptabl

miv72 [106K]

Answer:

In order to obtain a return of 9% per year, we need to invest $133,333.333 in low risk investments, $0 in mid risk investment and $66,666.666 in high risk investment.

Step-by-step explanation:

2/3 of the $200,000 for investment should go to low risk, and the other third to mid risk and high risk. Lets call X the amount that goes into high risk, then the amount that goes to mid risk is 200,000/3 - X.

If we want a 9% of return for the total investment, then we should end with $200,000 * 1.09 = $218,000. We can compute what money we expect to end the year with in terms of X and then obtain the value of X.

We end the year with

200,000 * 1.06 * 2/3 + (200,000/3 - X) * 1.09 + X * 1.15 = 214000 + X * (1.15 - 1.09) = 214000 + X * 0.06

Since we want this amount to be equal to 218000, then

214000+X * 0.06 = 218000

X*0.06 = 218000-214000 = 4000

X = 4000/0.06 = 66,666.666 = 200,000/3

Thus, we are not investing in the mid risk category.

In order to obtain a return of 9% per year, we need to invest $200,000/3 = $133,333.333 in low risk investments, $0 in mid risk investment and $66,666.666 in high risk investment.

If a sphere and a cone have the same radius and height how is the volume of a sphere related to the volume of a cone?

lorasvet [3.4K]

Answer:

The volume of the silo is about 142.3 cubic meters. Try It! The volume of a sphere is twice the volume of a cone that has the same circular base and height. The formula for the volume of a sphere with radius r is V= r3.

Step-by-step explanation:

Notice that if a cone and a sphere have equal radius, and if the cone has a height equal to its radius, then the cone will fill the sphere exactly four times. This means that the volume of the sphere is $4 times the volume of the cone.
