If k=100 - 4n what’s the value when n=60
dexar [7]
To solve this problem, start by plugging in your given n value.
This results in:
k = 100 - 4(60)

Next, simplify the parentheses by multiplying the -4 and the 60 together.
This leaves you with:
k = 100 - 240

To simplify for k, subtract 240 from 100 to get:
k = -140

So your final answer is k = -140 when n = 60

Which proportion can be used to find the arc length, s, in units?
Alinara [238K]

Answer:

Option B

Step-by-step explanation:

Formula to be used to calculate the length of an arc,

Length of arc = \frac{\theta}{360}(2\pi r)

Here, θ = Angle subtended at the center by the arc

r = radius of the circle

By substituting values in the formula,

s = \frac{150}{360}(2\pi )(42)

\frac{s}{2\times 42\pi }=\frac{150}{360}(\frac{2\times 24\pi }{2\times 24\pi } )

\frac{s}{84 \pi }=\frac{150}{360}

Therefore, Option B will be the answer.

Find the area of the prism help ASAP!!
stiks02 [169]
To find the surface area of a prism, we must find the area of each side and add them up.

Let's first find the area of the triangular base.

The area of a triangle is \dfrac{1}{2} bh
Where b is the base length and h is the height.

The base length of the triangle is 10.5. The height is 10.

A_B= \dfrac{1}{2}bh= \dfrac{1}{2} \times 10 \times 10.5=52.5

The triangular base has an area of 52.5 cm².

The triangular top must also have the same area. Thus, it also has an area of 52.5 cm².

Now we to find the length of the 3 rectangles on the side of the prism.

The formula for the area of a rectangle is A=wl
where w is the width and l is the length.

All rectangles have a width of 8. They all have different lengths. If we find the area of all the rectangles, we have the following:

A_1=8 \times 10.5 = 84

A_2=8 \times 10 = 80

A_3=8 \times 14.5=116

Now, add up ALL the areas we found. We'll have our surface area once we do this.

52.5+52.5+84+80+116=385

The surface area is 385 cm². Hope this helps! :)
