Part D Now that the power of is the same in both figures, you can just look at the first factors of each figure. So, how many times smaller or larger is the first factor of the mass of an average grain of table salt than the first factor of the mass of an average grain of rock salt?

Answers

Answer:

The first factor of the mass of an average grain of rock salt 120 is 40 times the first factor of the mass of an average grain of table salt 3.

Step-by-step explanation: Answer from edmentum Hope it helped!

Answer:

From part D, the mass of an average grain of rock salt is 120 x 10^-4. The first factor is 120.

The mass of an average grain of table salt is 3 x 10^-4. The first factor is 3. Let x times the first factor of the mass of an average grain of table salt be equal to the first factor of the mass of an average grain of rock salt.

3x = 120

x = 120/3

x = 40

So, the first factor of the mass of an average grain of rock salt (120) is 40 times the first factor of the mass of an average grain of table salt (3).

Step-by-step explanation:

Two students in your class, Hunter and Maggie, are disputing a function. Hunter says that for the function, between x = −2 and x = 2, the average rate of change is 0. Maggie says that for the function, between x = −2 and x = 2, the graph goes up through a turning point, and then back down. Explain how Hunter and Maggie can both be correct, using complete sentences. (10 points)

Answers

Answer:

Hunter and Maggie can both be correct because when the average rate of change is zero, the sum of all possible positive slopes and negative slopes on the interval will be zero. The sum of the possible positive slopes cancels out the sum of the possible negative slopes.

In this case the graph would be a parabola with the equation ax^2+bx+c where a is negative

According to hunter

In the interval [-2,2]

The average rate of change is 0

According to Maggie

The graph goes up through a turning point and back down

They can be correct

Because

If sum of all positive and negative slopes is zero then average rate of change is zeRos

So there is only one possibility

It's a parabolaThe turning point is vertex

Then they both are correct

The graph of f(x) is shown below. Estimate and list the value of x where f(x) has a horizontal tangent.

Answers

Using the critical point concept, it is found that f(x) has a horizontal tangent at x = 2 and at x = 7.

What are the critical points of a function?

The critical points of a function are the values of x for which:

[tex]f^{\prime}(x) = 0[/tex]

At these points, the behavior of the function changes from increasing to decreasing or vice-versa, and the tangent is horizontal.

Looking at the graph given in this problem, we see that the behavior changes from increasing to decreasing at x = 2, and from decreasing to increasing at x = 7, hence these are the values of x for which the tangent is horizontal.

Jennifer got a

triangular prism shaped box. is 7 inches long, and
the triangular base measures 3in x 4in X 5in. What iS
the surface area of the box of chocolates?

Answers

The surface area of the prism is the amount of space occupied by the box

The surface area of the box of chocolates is 47 square units

How to calculate the surface area

The height of the prism is given as:

Length (L) = 7 inches

The dimension of the base of the prism is given as:

Base (B) = 3 inches

Height (H) = 4 inches

Slant height (s) = 5 inches

The surface area of the prism is then calculated as:

[tex]Area =B * H + S * L[/tex]

So, we have:

[tex]Area =3 * 4 + 5 * 7[/tex]

[tex]Area =47[/tex]

Hence, the surface area of the box of chocolates is 47 square units

A chemist is using 332 milliliters of a solution of acid and water. If 17.3 p of the solution is acid, how many milliliters of acid are there? Round your answer to the nearest tenth.​

Answers

57.4 millilitres

We know that the chemist has 332 milliliters of the solution of acid and water, and 17.3% of that solution is acid.

We can then persume that the amount of acid in the solution is equal to 332ml × 17.3%

This is equal to 57.436ml.

Then the question states to round the answer to the nearest tenth.

Rounding 57.436ml to the nearest tenth (.1) will equal to 57.4ml.

Therefore, there are 57.4ml of acid in the solution rounded to the nearest tenth.

A game charges $0.99 for custom skins and a $9.99 membership fee. Write and expression that gives the
total cost in dollars for c number of skins and a membership.

Answers

Answer:

0.99c + 9.99

Step-by-step explanation:

We know one part of the expression is going to be $0.99c, since it's $0.99 per custom skin, and c is the number of custom skins were getting.

Then we must add on the 9.99 on top of that, since that is the one-time membership fee. This is what the equation looks like :

0.99c + 9.99

Hope this helps :)

Answer:

5. y = $0.99c + $9.99

Step-by-step explanation:

To find the cost, let us solve the equation for y:

Plug 5 as a replacement for c

y = 0.99(5) + 9.99

y = 0.99 × 5 + 9.99               multiply

y = 4.95 + 9.99                     add

y = 14.94

Therefore, the answer to number 6 is $14.94, which is the cost of 5 skins.

5. Tiana made lemonade for a sidewalk sale, and she sold 3/4 of it at the sale. After the sale, she
gave 3/2 gallons of the remaining lemonade to her cousins. If Tiana had 7/8 of a gallon left after the
sale and giving some to her cousins, how much lemonade, in gallons, did she start with?

Answers

The sum of the lemonade sold, the lemonade given to her cousins and

the amount left, gives the the amount of lemonade at the start.

Response:

The volume of lemonade with Tiana at the start is 9.5 gallons

How are arithmetic operations performed with fraction?

Given:

The amount of lemonade Tiana sold at the sale = [tex]\dfrac{3}{4}[/tex]

The amount of lemonade Tiana gave to her cousins = [tex]\mathbf{\dfrac{3}{2}}[/tex] gallons

The amount of lemonade Tiana had left = [tex]\dfrac{7}{8}[/tex] of a gallon

Required:

The amount of lemonade, Tiana started with

Solution:

Let x represent the amount of lemonade Tiana started with, we have;

[tex]x = \mathbf{\dfrac{3}{4} \cdot x + \dfrac{3}{2} \ gallons + \dfrac{7}{8} \ gallons}[/tex]

[tex]\mathbf{x - \dfrac{3}{4} \cdot x} = \dfrac{3}{2} \ gallons + \dfrac{7}{8} \ gallons[/tex]

[tex]\dfrac{1}{4} \cdot x = \dfrac{3}{2} \ gallons + \dfrac{7}{8} \ gallons = \dfrac{19}{8} \ gallons[/tex]

[tex]x = \dfrac{19}{8} \ gallons \times 4 = \mathbf{9.5 \ gallons}[/tex]

The volume of lemonade Tiana starts with is 9.5 gallons
