Answer: The value of x is 60 and two prime numbers are 2 and 3

Step-by-step explanation:

This is because 2 multiplied by 30 is 60 and 2 and 3 are prime numbers because their only factors are one and themselves.

Find the surface area of each figure to the nearest tenth.
Stells [14]
For the cylinder on the left-hand-side,

\bf \textit{surface area of a cylinder}\\\\
S=2\pi r(h+r)\quad 
\begin{cases}
r=radius\\
h=height\\
------\\
h=10\\
r=5
\end{cases}\implies S=2\pi (5)(10+5)

now, for the triangular prism on the right-hand-side,

notice is really just 2 triangles and 3 rectangles, stacked  up to each other at the edges.

the triangles have a base of 4, and a height of 1.5.

the rectangle on the left and the one on the right is a 6x2.5 rectangle.

the rectangle at the bottom, is a 4x6 rectangle.

adding their areas, is the area of the prism,

\bf \stackrel{two~triangles}{2\left[\cfrac{1}{2}(4)(1.5)  \right]}+\stackrel{left-right~rectangles}{2(6\cdot 2.5)}+\stackrel{bottom~rectangle}{4\cdot 6}

Find the point-slope form of the equation of the line passing through the points (5, –1) and (6, –8).
balandron [24]

Answer: y+1=-7 (x-5)

Step-by-step explanation:

The formula for point-slope form is y-y1= m (x-x1)

Step 1- Finding the slope by using formula    \frac{y2-y1}{x2-x1}:

(5,-1) (6,-8) or (x1, y1) (x2, y2)

-8+1 = -7

6-5 = 1

Slope + -7/1 or -7

Step 2- Then insert numbers in point slope form:

y-y1 = m(x-x1)

y+1 = -7 (x-5)

Mrs. Plum’s civics class is going on a field trip to observe the state legislature while it's in session. There are 24 students
Scrat [10]

Answer:

2024 ways

Step-by-step explanation:

Because order doesn't matter in this scenario, we can use the binomial function _nC_k, where n is the total number of items (students in this case) and k is the number of items we'd like to choose.

This binomial function is equivalent to:

_nC_k=\frac{n!}{(n-k)!*k!}, where n! means n * (n - 1) * (n - 2) * ... * 2 * 1

Here, we have _{24}C_3=\frac{24!}{(24-3)!*3!} =\frac{24!}{21!*3!} =2024.

Thus, the answer is 2024 ways.
