2*2 = 4
40/2 = 20

Micah needs half the number of birdseed bags in order to fill up a certain number of bird feeders. He would need 20 bags to fill up 40 feeders.

2 bags = 4 feeders
You need 40 feeders.
40 feeders (need to fill up) ÷ 4 (feeders per 2 bags) = 10
10 x 2 (bags) =
20 bags for 40 feeders

A suncatcher has 6 sections. Each section is in the shape of a parallelogram witha base of 12 cm and a height of 8 cm. What is t

jonny [76]

Answer:

576 cm²

Step-by-step explanation:

Given:

Number of sections in a suncatcher (n) = 6

Each section is in the shape of a parallelogram.

Base of parallelogram = 12 cm

Height of parallelogram = 8 cm

Now, area of a parallelogram is given as:

Area of parallelogram = Base × Height

Area of 1 parallelogram = 12 cm × 8 cm = 96 cm²

Now, there are 6 parallelogram shaped sections.

So, area of the sections = area of 1 section × total number of sections

∴ Area of 6 sections = 96 cm² × 6 = 576 cm²

Therefore, the total area of the sections of a suncatcher is 576 cm².

The distance from the ground of a person riding on a Ferris wheel can be modeled by the equation d equals 20 times the sine of t

kodGreya [7K]

We have the function d, representing the distance from the ground of a person riding on a Ferris wheel:

$d(t)=20\sin (\frac{\pi}{30}t)+10$

If we consider the position of the person at t = 0, which is:

$d(0)=20\sin (\frac{\pi}{30}\cdot0)+10=20\cdot0+10=10$

This position, for t = 0, will be the same position as when the argument of the sine function is equal to 2π, which is equivalent to one cycle of the wheel. Then, we can find the value of t:

$\begin{gathered} \sin (\frac{\pi}{30}t)=\sin (2\pi) \\ \frac{\pi}{30}\cdot t=2\pi \\ t=2\pi\cdot\frac{30}{\pi} \\ t=60 \end{gathered}$

Then, the wheel will repeat its position after t = 60 seconds.

Answer: 60 seconds.

Completely Factor the expression -18 P - 9

jekas [21]

can i have brainliest pls tyyy :)))

Answer:

-9(2p+1)

Step-by-step explanation:

-18p - 9

find the GCF (greatest common factor) for the expression.

-9

then, divide each term by the GCF

-18p / -9 -9 / -9

= 2p = 1

next, put the two terms you get when dividing into the final form of the answer:

GCF on the outside and quotients on the inside

-9(2p+1)

hope this helped! ;)
