I don’t have much advice, but I would make yourself a schedule and a to-do list so you stay in track, and know what you’re doing each day so you can hold yourself accountable and can’t have any excuses about “not knowing about the work” because if you’re organized and get it done fast, you will be able to know about all of you work and have beTter grades since you have more time to learn the material and turn it in on time

find the m and b of the table

Answers

9514 1404 393

Answer:

m = 1/2

b = -7

Step-by-step explanation:

The formulas for these can be used.

m = (y2 -y1)/(x2 -x1) . . . . . . . . . formula for slope given 2 points

m = (-9 -(-11))/(-4-(-8)) = 2/4

m = 1/2

b = y1 -m·x1 . . . . . . . . . . . . formula for y-intercept given slope and point

b = -11 -(1/2)(-8) = -11 +4

b = -7

Tony buys 2 boxes of chocolates. One is 4 in. 7 in. 8 in. And 8 in. 5 in. 6 in. Which box has the larger volume?

Answers

Answer:

Second box

Step-by-step explanation:

Volume (of the box) = length * width * height

Volume of first box is: 4 * 7 * 8 = 224

Volume of second box is: 8 * 5 * 6 = 240

Since 224 < 240, the volume of the second box has the larger value.

The coordinate bridge shows the cost of different numbers of bookmarks how many sense do for bookmarks cost.

Answers

Answer:

54 cents

Step-by-step explanation:

The cost of bookmarks relating to the number of bookmarks is given by the graph shown. Therefore:

From the graph, we can determine the relationship between the cost of bookmarks and the number of bookmarks by using two points. The equation of a line passing through points [tex](x_1,y_1)\ and\ (x_2,y_2)[/tex] is:

[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\[/tex]

From the graph, y represents the cost of bookmarks in cents and x represent the number of bookmarks. we can see that it passes through the point (2, 30) and (7, 90). Hence:

[tex]y-30=\frac{90-30}{7-2}(x-2)\\\\y-30=12(x-2) \\\\y-30=12x-24\\\\y=12x+6[/tex]

The cost of 4 bookmarks (x = 4):

y = 12(4) + 6

y = 54 cents

Select the two points that the line would go through. Practice on a piece of paper in front of you.

Cement costs $76 per cubic yard. What is the cost of cement for a sidewalk that is 4 in. Thick, 3ft wide,and 40 ft. Long?

Answers

Answer:

112.46 yd³

Step-by-step explanation:

1 inch = 0.0278 yds

1 feet = 0.333 yd

Thickness = 4 inches = (4 * 0.0278) = 0.1112 yds

Width = 3 feets = (3 * 0.333) = 0.999 yds

Length = 40 feets = (40 * 0.333) = 13.32 yds

Volume of sidewalk :

Thickness * Width * Length

0.1112 * 0.999 * 13.32 = 1.479702816 yd³

1 yd³ of cement = $76

Cost :

1.479702816 yd³ * $76

= 112.457414016

= 112.46 yd³

There are probably a couple of ways that you could do this. I'm going to pick the most obvious way.

Givens.

KN = 2.5

NO = 10

LM = 3

MP = x

Equation

NO/KN = PM / LM

Solution

10 / 2.5 = x / 3 Cross multiply

2.5x = 10 * 3 Combine

2.5x = 30 Divide by 2.5

x = 30/2.5

x = 12

That looks like it should be the answer, and it almost is, but you are asked for LP.

LP = LM + MP

LP = 3 + 12

LP = 15

The answer is 15

You have 0.2 liter of an acid solution whose acid concentration is 16 moles per liter. You want to dilute the solution with water so that its acid concentration is only 12 moles per liter. Use the given model todetermine howmany liters of water you should add to the solution.

Answers

Answer: 0.067 litres of water

Step-by-step explanation:

The mode is:

Concentration of new solution = Moles of acid in original solution / (Volume of original solution + Volume of water added)

Assume volume of water added is w.

12 = 16 (0.2) / (0.2 + w)

(0.2 + w) * 12 = 3.2

0.2 + w = 3.2 / 12

w = (3.2 / 12) - 0.2

w = 0.067 litres of water

The amount of water you should add to the solution is 0.067 liters.

Given

You have 0.2 liters of an acid solution whose acid concentration is 16 moles per liter.

You want to dilute the solution with water so that its acid concentration is only 12 moles per liter.

The concentration of new solution;

You can also use the solution dilution calculator in order to calculate the concentration of ions in a diluted solution.

The amount of water you should add to the solution is given;

[tex]\rm Concentration \ of \ new \ solution =\dfrac{\text{Moles of acid in original solution } }{\text{Volume of original solution + Volume of water added}}\\\\12=\dfrac{16(0.2)}{0.2+w}\\\\12 (0.2+w)=16(0.2)\\\\2.4 +12w=3.2\\\\12w=3.2-2.4\\\\12w=0.8\\\\w=\dfrac{0.8}{12}\\\\w=0.067[/tex]

Hence, the amount of water you should add to the solution is 0.067 liters.

bg=3 Solve the following equation for b. Be sure to take into account whether a letter is capitalized or not.

Answers

Answer:

Step-by-step explanation:

The equation for B would be as; B = 3/G

How can we find the solution to an equation?

We do same operations on both the sides so that equality of both expressions doesn't get disturbed. Solving equations generally means finding the values of the variables used in it for which the considered equation is true.

Sometimes we can find such value, and sometimes it is not possible at all, or sometimes, there are infinite number of solutions.

Remember that Solutions to an equation are those values of the variables involved in that equation for which the equation is true.

WE have the given equation as

BG = 3

To solve for the B, we have to eliminate the G from its side;

Then;

B = 3/G

Therefore , the equation for B would be as; B = 3/G
