What are the two shapes of cross sections we could create by slicing the pyramid

1 answer:

7 0

If you slice it horizontally you get a triangle at the top, and a trapezoid on the bottom
If you slice it vertically, you get 2 triangles.

PLEASE MARK BRAINLIEST!!!! Thanks

how would you write " The sum of one-third of a number, one-half of a number,and twice the number is thirty-four" as an equation

Rudik [331]

Answer: The required equation is $\dfrac{1}{3}x+\dfrac{1}{2}x+2x=34.$

Step-by-step explanation: We are given to write the following statement as an equation :

"The sum of one-third of a number, one-half of a number and twice the number is thirty-four".

Let the number be represented by x.

Then, one-third of the number is $\dfrac{1}{3}x,$ one-half of the number is $\dfrac{1}{2}x$ and twice the number is $2x.$

Therefore, as an equation, the given statement is written as:

$\dfrac{1}{3}x+\dfrac{1}{2}x+2x=34.$

Thus, the required equation is $\dfrac{1}{3}x+\dfrac{1}{2}x+2x=34.$

A central angle theta in a circle of radius 7 m is subtended by an arc of length 8 m. Find the measure of theta in degrees. (Rou

gogolik [260]

Answer: In degrees , The measure of $\theta=65.5^{\circ}$

In radians , the measure of $\theta =\dfrac{8}{7}\text{ radians}$ .

Step-by-step explanation:

We know that the formula for length of arc is given by :-

$l=\theta r$

, where $\theta$ = Central angle subtended by arc.

r= radius of the circle.

As per given , we have

Radius of circle : r=7 m

Length of arc : l= 8 m

Substitute these values in the above formula , we get

$8=\theta (7)\\\\\Rightarrow\ \theta =\dfrac{8}{7}\text{ radians}$

Hence, the measure of $\theta =\dfrac{8}{7}\text{ radians}$ .

To convert it into degrees we multiply it with $\dfrac{180^{\circ}}{\pi}$

The measure of $\theta =\dfrac{8}{7}\times\dfrac{180^{\circ}}{\pi}$

$=(\dfrac{8\times180}{7\times3.14})^{\circ}=65.5141037307^{\circ}$

$\approx65.5^{\circ}$

Hence, the measure of $\theta=65.5^{\circ}$
