A. A furniture truck is carrying five couches. Each couch weighs 250 pounds. How many
more couches are needed to increase the truckload to one ton?

Michelle pays $1365 in total.

Option D is the correct answer.

We have,

To calculate the total amount Michelle pays for the T-shirts, we need to consider the cost per shirt and the shipping fee.

The cost per shirt is $6.50, and she ordered 200 shirts, so the cost of the shirts alone is:

= $6.50 x 200

= $1300

The shipping fee is 5% of the total order, which is:

= 5% x $1300

= $65

To find the total amount Michelle pays, we add the cost of the shirts and the shipping fee:

= $1300 + $65 = $1365

Therefore,

Michelle pays $1365 in total.

Answer:

30% increase

Step-by-step explanation:

percentage increase is calculated as

[tex]\frac{increase}{original}[/tex] × 100%

increase = $35.10 - $27 = $8.10 , then

percentage increase = [tex]\frac{8.10}{27}[/tex] × 100% = 0.3 × 100% = 30%

Answer:

Step-by-step explanation:

step 1:       35.10-27 =8.1

step 2:       8.1/27 x 100 = 30%

so therefore = 30% increase

The equation for the parabola in the graph is the one in option C:

y = (-1/4)x² -2x - 7

Remember that a parabola with leading coefficient a and a vertex (h, k) can be written as:

y = a*(x - h)² + k

Here the vertx is at (-4, -3), then:

y = a*(x + 4)² - 3

And we can see that it passes through the point (0, -7), replacing that we will get:

-7 = a*(0 + 4)² - 3

-7 = a*16 - 3

-7 + 3 = a*16

-4 = a*16

-4/16 = a

-1/4 = a

The quadratic is:

y = (-1/4)*(x + 4)² - 3

Expanding that, we will get:

y = (-1/4)x² -2x - 4 - 3

y = (-1/4)x² -2x - 7

The correct option is C.

Answer:  d. Y=2

Step-by-step explanation:

They are similar because AB is four more than ED, AC is three more than DF, and BC is three more than EF.

To determine if two triangles are similar, we need to compare the ratios of the corresponding sides.

In this case, the given information allows us to compare the lengths of the corresponding sides of triangle ABC and triangle DEF.

We have:

AB = 16 and ED = 12 (AB is four more than ED)

AC = 12 and DF = 9 (AC is three more than DF)

BC = 1 and EF = 9 (BC is three more than EF)

The corresponding sides are proportional because the ratios of the lengths are consistent:

AB/ED = 16/12 = 4/3

AC/DF = 12/9 = 4/3

BC/EF = 1/9

Since the ratios of the corresponding sides are the same, we can conclude that triangle ABC and triangle DEF are similar

The probability P(G|N) value is 0.585 when P(G∩N)=0.24, P(G)=0.37, and P(N)=0.41.

To find P(G|N), which represents the probability of event G given event N, we can use the formula:

P(G|N) = P(G∩N) / P(N)

Given that P(G∩N) = 0.24 and P(N) = 0.41

Answer:

(-5, -5)

Step-by-step explanation:

Given system of linear inequalities:

[tex]\begin{cases}y < \dfrac{1}{2}x+5\\\\y\leq-3x-2\end{case}[/tex]

When graphing inequalities:

To graph linear inequalities, treat them as equations (swap the inequality sign for an "equals" sign). Plug in two values of x to find two points on the line to help draw the lines.  

Substitute x = 0 and x = 6 into the equation of the inequality to find two points on the line.

[tex]\begin{aligned}x=0 \implies y&=\dfrac{1}{2}(0)+5\\y&=5\end{aligned}[/tex]               [tex]\begin{aligned}x=6 \implies y&=\dfrac{1}{2}(6)+5\\y&=8\end{aligned}[/tex]

Plots points (0, 5) and (6, 8).

As the inequality sign is <, draw a dashed line through the plotted points and shade below the line.

Substitute x = 0 and x = 2 into the equation of the inequality to find two points on the line.

[tex]\begin{aligned}x=0 \implies y&=-3(0)-2\\y&=-2\end{aligned}[/tex]               [tex]\begin{aligned}x=2 \implies y&=-3(2)-2\\y&=-8\end{aligned}[/tex]

Plots points (0, -2) and (2, -8).

As the inequality sign is ≤, draw a solid line through the plotted points and shade below the line.

The solution set is the set of points contained within the overlapping shaded region and on the solid line.

Therefore, a point in the solution set is (-5, -5).

Adjacent angles are two angles that share a common side.

The required sign that makes the statement true is "||".

The given options are 7, 22, 64, and V.

To express a percentage in mathematical notation, we divide the number by 100. In this case, 67.18% can be written as 0.6718.

The rate of change of y with respect to x for the given linear relationship is 10.

To determine the rate of change of y with respect to x, we can calculate the slope of the linear relationship between x and y using the formula:

slope = (change in y) / (change in x)

Given the values in the table:

x: -8.5, -6.5, -2.5, -1

y: -92, -72, -32, -17

We can calculate the change in y and change in x between any two points.

For example, between the first two points (-8.5, -92) and (-6.5, -72), the change in y is:

change in y = -72 - (-92) = -72 + 92 = 20

And the change in x is

change in x = -6.5 - (-8.5) = -6.5 + 8.5 = 2

Using the formula for slope:

slope = (change in y) / (change in x) = 20 / 2 = 10.

Therefore, the rate of change of y with respect to x is 10.

This means that for every unit increase in x, y increases by 10 units.

We can perform the same calculations for the other points in the table and observe that the rate of change of y with respect to x remains constant at 10.

Hence, the rate of change of y with respect to x for the given linear relationship is 10.

Answer:

Unknown but formula (Check step by step solution)

Step-by-step explanation:

Without the image of the base of the crayon, I cannot determine the exact dimensions of the triangular prism or calculate the volume of a single crayon. However, I can give you a general formula for calculating the volume of a triangular prism and use it to find the total volume of wax needed to make a box of 8 crayons.

The formula for the volume of a triangular prism is:

Volume = (1/2) x base x height x length

where base is the area of the base of the triangular prism, height is the height of the triangular prism, and length is the length of the triangular prism.

Assuming all the crayons in the box have the same dimensions, let's say the base of the triangular prism has a length of L and a width of W. We can calculate the area of the base of one crayon as:

Base area = (1/2) x L x W

Since the crayon is 90 millimeters long, its height is 90 millimeters. Therefore, the volume of one crayon is:

Volume of one crayon = (1/2) x L x W x 90

To find the total volume of wax used to make a box of 8 crayons, we can multiply the volume of one crayon by the number of crayons:

Total volume of wax = Volume of one crayon x 8

Total volume of wax = (1/2) x L x W x 90 x 8

Total volume of wax = 360 x L x W

Again, without knowing the exact dimensions of the triangular prism, I cannot calculate the total volume of wax used to make a box of 8 crayons. But you can use the formula above and substitute the values of L and W based on the dimensions of the base of the crayon to find the answer.

The data set with the greater range is greater for girls. The median is greater for girls.

The range of a dataset is the difference between the maximum and minimum values in the set.

The median is the middle value in a sorted dataset, or the average of the two middle values if the set has an even number of elements.

To determine which dataset has a greater range, you need to compare the difference between the highest and lowest values of the two datasets.

To determine which dataset has a larger median, you need to sort the datasets and find the middle value(s).

The range for boys is 60 as for girls the range is 80. The median for boys is 90 and for girl 110.
