The correct question is
Peyton is a sprinter who can run the 40-yard dash in 4.5 seconds. He converts his speed into miles per hour, as shown below
Which ratio is incorrectly written to convert his speed?

the picture in the attached figure

we know that
The term (5280 ft/1 mi) is incorrect
"Feet" needs to be on the bottom to cancel with the previous term.
"Mile" needs to be on top in the numerator so that the answer can be expressed in "miles per hour"

the correct term is (1 mi/5280 ft)

Use the gcf and the distributive property to express the sum as a product 20 35

Maslowich

Common factor of 20= 1,2,4,5,10.......
common factor of 35=1,5,7.............
so here we find that 1 and 5 r the common factors
but the GCF of 20 and 35 is 5
so,
by using GCF the distributive property is : 5(4+7)

Jami is trying to model the movement of a tire. In order to properly model the movement, she is going to focus on the movement o

USPshnik [31]

From the given data it is clear that the amplitude of the wave will be 9 inches.

It is also clear that the speed of rotation, ω, will be: $\omega=\frac{2\pi}{T}=\frac{2\pi}{8}=\frac{\pi}{4}$

Now, it is given that the nozzle is on the right side of the tire and that position is going to be treated as the equilibrium position, the tire is then rotated such that the nozzle goes up at the beginning of the rotation. This condition is possible only when we have a Sine (Sin) function.

Thus, our final answer can be arrived as:

$Amplitude\times Sin(\omega t)$

$9\times sin(\frac{\pi}{4}t) =9sin(\frac{\pi}{4}t)$

Thus, out of the given options, option B is the correct answer.

Total weight of the 8 backpacks = 8 x 14 = 112 pounds

Total weight of the 12 backpacks = 12 x 9 = 108 pounds

Total weight of all the 20 backpacks = 220 pounds

Mean weight of the 20 backpacks = 220 ÷ 20 = 11 pounds

----------------------------------------------------------------------------------------
Answer: The mean weight of the 20 backpacks is 11 pounds

Factor x2 – 4x – 5 = 0. WITH ALL STEPS.

Troyanec [42]

x²-4x-5=0

The given equation is quadratic

So we can perform prime factorisation of it.

factors of -5, that add up to give -4 are -5 and 1

therefore replacing -4x by -5x+x

x²-5x+x-5=0

performing factoring by grouping,

(x²-5x)+(x-5)=0

x(x-5)+(x-5)=0

(x+1)(x-5)=0

x+1=0 and x-5=0

Answer is x=-1 and x=5
