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.
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.

6. A two-story building measures 21 feet
from the ground. A scale model shows the
building to be 3 inches tall. How many inches
would an 84 foot building be in the model?
height:
Answer:
12
Step-by-step explanation:
First figure the ratio of the real building to the model which is 21 divide 3. So the ratio is 1:7, since we're finding the height of the model, we divide 7 by 84 which is 12
Jennifer got a
box of chocolates. The box is a right
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?
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 areaThe 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

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?
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).

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.
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.
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)
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 0According to Maggie
The graph goes up through a turning point and back downThey 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 vertexThen they both are correct
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?
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 gallonsHow 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 gallonsLearn more about fractions here:

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