Answer:

30 yards for 24 vs 1 foot for 25 cents

so lets multiple the yards by 3 to see how many feet

90 feet = 30 yards

90 feet 24 dollars

now lets divide 90 by 24

3.75 so 3.75 per foot

so the second one is way better

Hope This Helps!!!

Answer:

150 feet at $.25 per foot ($.75 per yard) is the better buy.

Step-by-step explanation:

150 feet is equal to 50 yards. So 2 30-yard spools would be $48. $48 for 60 yards equals $.80 per yard. So 150 feet at $.25 per foot ($.75 per yard) is the better buy.

The volume that is left to be filled is approximately: 3,332.6 in.³

Volume of a box = (length)(width)(height)

Given the following:

Volume of the bat = 82 cubic in.

Length of box = 30 in.

Width = 18.97 in.

Height = 6 in.

The remaining volume to be filled = volume of box - volume of bat

= (30)(18.97)(6) - 82

If the cost of equity is 12% , cost of debt 10%, tax rate 25%, 20 million market value of debt , 60 million market value of equity then the weighted average cost of capital is 10.875%

Given cost of equity is 12% , cost of debt 10%, tax rate 25%, 20 million market value of debt , 60 million market value of equity.

We know that weighted average cost of capital= cost of equity* weight of equity+ cost of debt* weight of debt.

Cost of debt (consider after tax)=10%(1-25%)

=10%*0.75

=0.075

Weight of equity=60/80

=0.75

Weight of debt=20/80

=0.25

Weighted average cost of capital=12%*0.75+0.075*0.25

=0.09+0.01875

=0.10875

The value of sec(V) is 5/3

The tangent is given as:

tan(V) = 4/3

To solve for sec(V), we use the following identity

sec^2(V) = tan^2(V) + 1

So, we have:

sec^2(V) = (4/3)^2 + 1

This gives

sec^2(V) = 16/9 + 1

Evaluate the sum

sec^2(V) = 25/9

Take the square root

sec(V) = 5/3

Hence, the value of sec(V) is 5/3

The swimsuits that can be produced with the new partner is  23,043.

The swimsuits that can be produced without the partner is  16,521.

The equation that relates total cost, operating cost and cost per swimsuit together is

Total cost = operating cost + (cost per swimsuit x number of swimsuits)

500,000 = 120,000 + ($23x s)

500,000 - 120,000 = 23s

380,000 = 23s

s = 380,000 / 23

s = 16,521

Number of swimsuits that can be produced with the new partner:

(500,000 + 150,000)  = 120,000 + ($23x s)

650,000 = 120,000 + 23s

650,000 - 120,000 = 23s

By applying the law of cosine, the length of side CE is equal to 9.22 cm and the image of right-angled triangle BCE is shown in the image attached below.

In order to determine the length of side CE, we would apply the law of cosine because both side CE and side BC respectively represent the adjacent side and hypotenuse of right-angled triangle BCE.

cos(θ) = Adj/Hyp

Where:

Substituting the parameters into the formula, we have;

cos(θ) = CE/BC

cos(11.46) = CE/9.41

Cross-multiplying, we have:

CE = 9.41 × cos(11.46)

CE = 9.41 × 0.9801

CE = 9.22 cm.

200 cupcakes

Step-by-step explanation:

12 cupcakes = 6%

12/x=6/100 6x=1200 x=200

so 200 cupcakes

hope this helps

The total number of cupcakes the bakery sells that day is 200.

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

Given that,

A bakery sold 12 vanilla cupcakes in a day, which is 6% of the total cupcakes.

Let's say the total cupcakes were x

Then,

6% of x = 12

6 × x/100 = 12

Divide both sides by 6

x/100 = 2

Multiply both sides by 100

x = 200

Hence "The total number of cupcakes the bakery sells that day is 200".

Answer:

undefined - you can't divide by 0!

Step-by-step explanation:

m = [tex]\frac{y2-y1}{x2-x1}[/tex]

m = [tex]\frac{10-(-8)}{1-1}[/tex]

m = 18/0

In order to find the slope, we have the formula is

The change of Y (Also Y minus each other)

----------------------------------------------------------------- Over (As fraction

The change of X (Also X minus each other)

Now the first point is (1,10) The Y is 10

                                               The X is 1

Now the Second Point is (1,-8) The Y is -8

                                                     The X is 1

So now we plug the numbers in

10-(-8)

Answer: The person who covered the most tiles is Bruce, because 1/4 is bigger than 1/9.

Step-by-step explanation:

Answer:

y = -4x + 25

Step-by-step explanation:

You are given the slope, but you can find the slope using 2 points.  Slope is the change in y over the change is x.  Your two y's are 1 and 9.  Your two x's are 6 and 4.

1-9/6-2  

1 - 9 = -8

6-4 = 2

-8/2 is -4.

We want an equation in the form y = mx +b.  We have the m (slope), we now just need the b.  We take either of the ordinal points (4,9) or (6, 1) to find b.  They will both work, but the question tells us to us (4,9).  4 is the x and 9 is the y.

y = mx + b

9 = (-4)(4) + b  a negative times a positive is a negative.

9 = -16 + b  Add 16 to both sides

25 = b

We know now m which is -4 and b which is 25.  We plug them into the model y = mx + b

y = -4x + 25
