Answer:

a. 1.2 minutes

b. 0.83 laps

c. 25.2 minutes

Step-by-step explanation:

Lin runs 5 laps around a track in 6 minutes.

a. How many minutes per lap is that?

5 laps = 6 minutes

1 laps = x minutes

Cross Multiply

x minute × 5 laps = 6 minutes × 1 laps

x minute = 6 minutes × 1 laps/5 laps

x laps = 1.2 minutes

Hence, it is 1.2 minutes per lap

b. How many laps per minute is that?

6 minutes = 5 laps

1 minute = x laps

Cross Multiply

6 minutes × x laps = 1 minute × 5 laps

x laps = 1 minute × 5 laps/6 minutes

x laps = 0.8333333333 laps

Hence, it is 0.83 laps per minute.

c. If Lin runs 21 laps at the same rate,

5 laps = 6 minutes

21 laps = x minutes

Cross Multiply

x minute × 5 laps = 6 minutes × 21 laps

x minute = 6 minutes × 21 laps/5 laps

x laps = 25.2 minutes

Hence, it takes her 25.2 minutes

The width,w, of a rectangular garden is X -2 the area of the garden is X^3-2X-4 what is an expression for the length of the gard

slamgirl [31]

$A=lw \Rightarrow l=\frac{A}{w}$
A - area, l - length, w - width

$w=x-2 \\
A=x^3-2x-4 \\ \\
l=\frac{x^3-2x-4}{x-2}=\frac{x^3-2x^2+2x^2-4x+2x-4}{x-2}=\frac{x^2(x-2)+2x(x-2)+2(x-2)}{x-2}= \\
=\frac{(x^2+2x+2)(x-2)}{x-2}=x^2+2x+2$

The answer is D. x²+2x+2.

A pie has been in the oven for some number of minutes. it needs to bake for a total of 60 minutes. for how many more minutes mus

Lesechka [4]

The pie must stay for 60 - x more minutes must the pie bake

<h3>For how many more minutes must the pie bake?</h3>

Let the amount of time spent in the oven be x

So, we have

Total amount of time = 60 minutes

This means that

Remaining time + Amount of time spent = 60

This gives

Remaining time + x = 60

Evaluate

Remaining time = 60 - x

Hence, the pie must stay for 60 - x more minutes must the pie bake
