Can some one pls help me

Leviafan [203]

Answer:

10.5in

Step-by-step explanation:

DC=16in is similar to OP=12in.

So the ratio is 12/16=3/4.

Now AD=14in.

MP=AD×ratio=14×3/4=21/2=10.5in

Tell whether x and y show direct variation. x + y = 6

Over [174]

<h3>Answer: Not direct variation</h3>

The reason why is because it can't be written in the form y = kx

If we solved the given equation for y, we get y = -x+6. It has a y intercept of 6, but it should be zero if we wanted a direct variation equation.

A cone shaped popcorn cup has a radius of 5 cm and a height of 9cm. How many cubic cm of popcorn can the cup hold? Use 3.14 as a

katovenus [111]

Answer:

The cup can hold <u>235.5 cubic cm</u> of popcorn.

Step-by-step explanation:

Given:

A cone shaped popcorn cup has a radius of 5 cm and a height of 9cm.

Use 3.14 as an approximation for pi.

Now, to find cubic cm of popcorn the cup can hold.

Radius ( r ) = 5 cm.

Height ( h ) = 9 cm.

π = 3.14 ( as per question ).

So, to get the cubic cm of popcorn the cup can hold we put formula of volume:

$Volume = \pi r^2\frac{h}{3}$

$Volume=3.14\times 5^2\times \frac{9}{3}$

$Volume=3.14\times 25\times 3$

$Volume=235.5\ cubic\ cm.$

Therefore, the cup can hold 235.5 cubic cm of popcorn.
