From the figure of triangles, scale factor of A and B, the value of x = 3

According to the question, given that

when two triangle are same, then we easily get missing value x

From the figure, two triangle are similar in it thus,

[tex]\frac{x}{1}[/tex] = [tex]\frac{9}{3}[/tex]       {property of triangles which are similar}

x = [tex]\frac{9}{3}[/tex] .

x = 3

Therefore, we get scale factor of triangle A and B, the missing value of missing x = 3.

Scale factor is the proportion of an original object's scale to a new one that is a representation of it but is a different size (bigger or smaller).

For example, if we have a rectangle of sides 4 cm and 6 cm, we can enlarge it by multiplying each side by a number, say 4. The new figure we get will be similar to the original figure, but all its dimensions will be twice that of the original rectangle.

The total volume taken by the coins is 88.47 cubic inches, so the correct option is D.

The coins are cylinders with a radius of 1.4 inches and a height of 0.0625 inches.

Remember that the volume of a cylinder is given by:

volume = (height)*pi*(radius)^2

Where pi = 3.14

Then here the volume of each coin is:

V = (0.0625 in)*3.14*(1.4 in)^2 = 0.384 in³

And there are 230 coins, so the total volume is:

V = 230*0.384 in³ = 88.47 in³

So the correct option is D.

Answer: D: 88.47 in³​

Step-by-step explanation: So what you want to do is first find the individual volume of the coins. Use the volume formula: V = πr^2h

Take 1.4 and times it by itself

1.4 x 1.4 = 1.96

Now multiply 1.96 by 0.0625

1.96 x 0.0625 = 0.1225

And times 0.1225 by pi, or in this case, 3.14

0.1225 x 3.14 = 0.38465

Now you have found the individual volume of each coin. You are trying to find how much space all of the coins take up together. The question says that there is 230 coins in total. So times 0.38465 by 230 to find how much space all the coins take up.

0.38465 x 230 = 88.4695 in³
Now round it to the nearest hundredth: 88.47 in³

That is your answer.

Also I took the same test and I picked 88.47 inches cubed and got it right.

We take a look at the inequalities y > 2 and x >4. This means that the solutions must have values that has x > 4 and y > 2. Letters A, C, and E are candidates to be solution since they satisfy the inequalities provided. Using the inequality y > x, this means that the y value must be greater than the x value that we have. Letter A has higher x value than y value, hence, it will be crossed out. Both C and E has higher y values compared to their x values. Hence, the points that are solution to the system of inequalities provided are C. (9, 10) and E. (5, 6).

Factor the left hand side:

Subtract 2x from both sides:

Sutract 1 from both sides:

Divide both sides by 10:

The equation to determine the number of players the team can bring is $842.50 + $21.50y = $1,186.50

The team can bring 16 players to the tournament.

To go to a tournament, softball team members raised $1186.50 and rented a bus for $842.50, and the cost of meals of each player is $21.50.

Let y represent the number of players.

$842.50 + $21.50 × y = $1,186.50

$842.50 + $21.50 × y = $1,186.50

$842.50 + $21.50y = $1,186.50

Subtracting $842.50 from each side.

$21.50y =  $1,186.50 - $842.50

$21.50y =  $344

Divide both side of the equation by $21.50.

x = $344 / $21.50

x = 16 players

As a result, the team is allowed to enter 16 players into the competition.

The change that Grant received to the nearest cent after giving the delivery driver with a $100 bill is $ 32.6.

This is a question of percentages.

Given that:-

Price of bouquet of flowers = $ 55

Sales tax % = 6.5 %

Tip % = 15 %

Delivery fee= $10

We have to find the change that Grant received to the nearest cent after giving the delivery driver with a $100 bill.

Sales tax = (6.5/100)*55 = $3.575

$55 + $3.575 = $58.575

Tip = (15/100)*58.575 = $ 8.78625

Total money paid by Grant = 55 + 3.575 + 8.78625 = $ 67.36125 ≈ $ 67.4

Dilation by a scale factor of 2 with the origin (0, 0) as the center of dilation, followed by a translation of 3 units right.

Step-by-step explanation:

Given vertices of triangle ABC:

If two triangles are said to be similar:

To keep the corresponding angles of both triangles the same and maintain similarity, dilate triangle ABC.

If we compare the coordinates of B (1, 4) and B' (5, 8), the y-value has been multiplied by 2.

Therefore, the first step of the transformation is a dilation by a scale factor 2 with the origin (0, 0) as the center of dilation.

⇒ (1 × 2, 4 × 2) = (2, 8)

After multiplying the coordinates of B by two, the difference between the x-values of the dilated point and B' is 3, so the second step of the transformation is a translation of 3 units right.

Therefore, the series of transformations is:

Mapping Rule:  (x, y) → (2x+3, 2y)

Therefore, the coordinates of point C' are:

⇒ C' = (2(5) + 3, 2(2)) = (13, 4)

Answer:   (13, 4)

The translation vector from B(1,4) to C(5,2) is <4,-2> since we move to the right 4 units, and down 2 units. It's the shorthand way of writing [tex](x,y) \to (x+4,y-2)[/tex]

Double the coordinates of the translation vector <4,-2> to get <8,-4>

If we started at point B'(5,8) and followed the pathway "right 8, down 4" then we arrive at C'(13,4) as one possible answer.

We could express the steps like this

[tex](\text{x},\text{y})\to(\text{x}+8,\text{y}-4)\\\\(5,8)\to(5+8,8-4)\\\\(5,8)\to(13,4)\\\\[/tex]

As I mentioned in the link above, there are infinitely many answers because we can change the scale factor to any nonnegative real number. For instance we could triple the coordinates of <4,-2> to get <12,-6> and follow the same outline of steps to get C'(17,2) as another possible answer.

From the given table, it is found that:

a. The weight function is linear, as it has a constant rate of change.

b. The equation for the linear function is: W(x) = 0.85x + 2.22.

Linear functions are modeled according to the following rule:

y = mx + b.

In which the coefficients are:

The slope is the rate of change, and it has to be constant for the relation to be a linear function.

Relating the number of cans x and the cost of the cans C(x), the slope can be calculated as follows:

Different slopes, hence the cost function is not linear.

For the weight function, the slope can be calculated as follows:

Due to the constant rate of change, the weight function is a linear function.

Considering the slope of m = 0.85, the weight function can be written as follows:

W(x) = 0.85x + b.

When x = 8, W(x) = 6.8, hence the intercept b is found as follows:

8 = 0.85(6.8) + b

b = 8 - 0.85 x 6.8

b = 2.22.

Then the function is:

W(x) = 0.85x + 2.22.

Answer:

That depends on what exactly is meant by "$3 in equipment fees". Is that per hour, per day or what?

Assuming per hour, he makes $7 per hour but pays $3 for a profit of $4 per hour. So, to make at least $39, he'd have to work 39/4 or 9 3/4 hours.

Now, if his equipment fee is daily, then he would need to earn at least $42 in a day to profit at least $39. Thus, he'd have to work at least 42/7 or 6 hours to make that much profit.

Step-by-step explanation:

In order to find what factors could represent the length and the width, we need to factor the polynomial that represents the area.

To do so, first let's find the zeros a1 and a2, then we can factor as follows:

Where k is the coefficient of the quadratic term (so k = 12).

Using the quadratic formula, we have:
