Lyla grew 16 flowers with 2 seed packets. How many seed packets does Lyla need to have a total of 40 flowers in her garden? Assu

Tresset [83]

Answer:

Lyla needs 5 seed packets to have 40 flowers in her garden

Step-by-step explanation:

* Lets explain the direct proportion

- Direct proportion is the relationship between two variables when

their ratio is equal to a constant value

- If m and n are in direct proportion m ∝ n , then m = kn, where

k is constant

- We can write the direct proportion as m/n = k

* Lets solve the problem

- Lyla grew 16 flowers with 2 seed packets

- The relationship between the number of flowers and the number

of the seed packets is direct proportional

∴ F ∝ P , where F is the number of the flowers and P is the number

of the seed packets

∵ F = kP

∵ F = 16 when P = 2

∴ 16 = k(2)

- Divide both sides by 2

∴ k = 8

- Substitute the value of k in the equation

∴ F = 8P

Lets find how many packets does Lyla need to have 40 flowers

∵ F = 40

∴ 40 = 8P

- Divide both sides by 8

∴ P = 5

∴ Lyla needs 5 seed packets to have 40 flowers in her garden

Sophia manages a landfill. She decides to measure the rate at which trash increases in volume to fill the landfill as the number

goblinko [34]

Answer:

$\frac{m^3}{h}, \frac{cm^3}{h}, \frac{km^3}{h}$

Step-by-step explanation:

If you look at the objects thrown as garbage, it's a two- or three-dimensional item that takes up space and also has mass and this is a solid waste.

And the landfill that dumps such garbage is also three-dimensional.

Hence, the volume module, if the object inside is a solid, either would be

$m^3,cm^4,Km^3$

As household numbers rise, landfill space increases.

So,

$household\ number = Proportionality\times landfill\ space$

If H represents the number of household keeps, then it will be a sufficient unit for the purpose of Sophia that is

$\frac{m^3}{h}, \frac{cm^3}{h}, \frac{km^3}{h}$

Prove the following

jenyasd209 [6]

Answer:

Step-by-step explanation:

sin(180°-∅)=sin∅ as its in the 2nd quadrant

then tan(180°-∅)= -tan∅ as its in the 2nd quadrant and there only sin and cosec is positive and at last cos(180°-∅) = -cos∅ for the same reason

so by putting the values:

sin∅/sin∅ + -tan∅/tan∅ + -cos∅/cos∅ =1-1-1= -1

thanks ..
