Answer:34.5

Step-by-step explanation:

86-51.5= 34.5

Answer:

B. 50

Step-by-step explanation:

For two stilts, you'd multiply 13 by two.

2(13) = 26

For twelve rungs you multiply 2 by 12.

12(2) = 24

Then you add the two numbers together to see how much would she needs.

24 + 26 = 50

This gives you the answer, which is equivalent to B.

Step-by-step explanation:

so, i might be wrong but i hope this helps.

The slope will be the same for a straight line no matter which two points you pick as you know. All you need to do is to calculate the difference in the y coordinates of the 2 points and divide that by the difference of the x coordinates of the points(rise over run). That will give you the slope.

Answer:

Not sure I understand your question.

If the tax rate is 6.25% and you need the tax from $73.97, tax is:

= 6.25% * 73.97

= $4.62

Converting 6.25% to decimal.

First understand that when a percent sign(%) is next to a number it means that the number is a fraction and its denominator is 100.

6.25% = 6.25/100

To convert to decimal, divide the numerator by the denominator:

= 6.25 ÷ 100

= 0.0625

Answer: F

Step-by-step explanation: 5+6+7x8=67

Answer:

55 ft.

Step-by-step explanation:

First find the area of Lot X

67 • 70 = 4,690

Subtract the are of Lot X from the total area

8,375 - 4,690 = 3,685

3,685 is the area of Lot Y

Now divide 3,685 by the length of Lot Y : 67

3,685 ÷ 67 = 55

The width of Lot Y is 55 ft.

Hope this helps!

Answer:

radius r = 3.414 in

height h = 6.8275 in

Step-by-step explanation:

From the information given:

The volume V of a closed cylindrical container with its surface area can be expressed as follows:

[tex]V = \pi r^2 h[/tex]

[tex]S = 2 \pi rh + 2 \pi r^2[/tex]

Given that Volume V = 250 in²

Then;

[tex]\pi r^2h = 250 \\ \\ h = \dfrac{250}{\pi r^2}[/tex]

We also know that the cylinder contains top and bottom circle and the area is equal to πr²,

Hence, if we incorporate these areas in the total area of the cylinder.

Then;

[tex]S = 2\pi r h + 2 \pi r ^2[/tex]

[tex]S = 2\pi r (\dfrac{250}{\pi r^2}) + 2 \pi r ^2[/tex]

[tex]S = \dfrac{500}{r} + 2 \pi r ^2[/tex]

To find the minimum by determining the radius at which the surface by using the first-order derivative.

[tex]S' = 0[/tex]

[tex]- \dfrac{500}{r^2} + 4 \pi r = 0[/tex]

[tex]r^3 = \dfrac{500 }{4 \pi}[/tex]

[tex]r^3 = 39.789[/tex]

[tex]r =\sqrt[3]{39.789}[/tex]

r = 3.414 in

Using the second-order derivative of S to determine the area is maximum or minimum at the radius, we have:

[tex]S'' = - \dfrac{500(-2)}{r^3}+ 4 \pi[/tex]

[tex]S'' = \dfrac{1000}{r^3}+ 4 \pi[/tex]

Thus, the minimum surface area will be used because the second-derivative shows that the area function is higher than zero.

Thus, from [tex]h = \dfrac{250}{\pi r^2}[/tex]

[tex]h = \dfrac{250}{\pi (3.414) ^2}[/tex]

h = 6.8275 in

Step-by-step explanation:

a) Data:

Basic charge = 11.6 cents (0.116)

Charge for the first 10 kWh = 4.59 cents (0.0459)

Charge for additional usage above 10 kWh = 9.71 cents (0.0971)

b) Each kWh consumed or not attracts the basic charge of 11.6 cents.  The first 10 kWh consumed is billed at 4.59 cents, while the additional kWh consumed is charged at 9.71 cents.  The charge per consumption is first totaled in cents before being converted to dollars by dividing by 100.

Answer:

y = 1/2x + 1

Step-by-step explanation:

In order to evaluate a slope that is perpendicular to the given equation, you need to find the opposite reciprocal of the original slope. This means you take the original slope, flip the numerator and the denominator, and change the sign in front.

-2 ⇒ 1/2

Next, we need to substitute the information given into the point-slope formula.

The point-slope formula is:

y - y₁ = m(x - x₁)

y - 1 = 1/2(x - 0)

y - 1 = 1/2x

y = 1/2x + 1

Therefore, the line perpendicular to y = -2x + 2 is y = 1/2x + 1.
