The answer of the question is 5,280 foot per minutes because on miles per hour in foot per minute is 88 foot per minutes and then you multiply by 60.

Answer:

5280 ft/min.

Step-by-step explanation:

We need to know that 1 mile = 5280 feet or $\frac{5280 feet}{1 mile} = 1$ . Then

$60 \frac{mi}{h}\frac{5280 feet}{1 mi} = 60*5280\frac{feet}{h}= 316800\frac{feet}{h}$ .

Now, we nee dto know that 1 hour = 60 minutes or $\frac{1 hour}{60min} = 1$ . Then,

$316800\frac{feet}{h}\frac{1 h}{60min} = \frac{316800}{60}\frac{feet}{min} = 5280\frac{feet}{min}$ .

Eddi Din [679]

Answer:

We are given number of miles the 3 bike trips they took last month = 45.7, 40.9, and 38 miles.

Sam and Bruno were computing how many kilometers.

Also one kilometer equals 0.621 miles.

From this we can see than 1 kilometer is smaller unit and a mile is a larger unit.

In order to convert number of miles into kilometers, we need to divide each number of mile by 0.621 miles.

We always divide a larger value by a smaller value to get the smaller unit.

Therefore,

Bruno is correct. When going from a larger unit to a smaller unit you need to divide.

Step-by-step explanation:

Hopefully this helped, if not HMU and I will get u a better answer.

-Have a great day! :)

Which of the following equations is written in standard form?

Harlamova29_29 [7]

Standard Form is ax + by = c, where a, b, and c are not fractions and a is not negative.

So, you can go through each of your options to see which ones work with those rules.

A. 2.5x + 3y = 12 No, this is not in Standard Form. 2.5 can be rewritten as 2 $\frac{1}{2}$ , menaing A is a fraction, which you can't have.

B. -10x - 3y = 1 No, this is not in Standard Form. A is -10, but A can't be negative.

C. 2x + 3y = 12 Yes, this is in Standard Form. It follows all of the rules.

D. 5x + 5y = 10 Yes, this is in Standard Form. It follows all of the rules.

So, C and D are both written in Standard Form.

nevsk [136]

Answer: $2800

Step-by-step explanation:

if the function is f(x) and shes already saved $1000 plug in the functions, or in other words plug in x for weeks.

1000 + 150 x

(plug in x)

1000 + 150 x 12

so now you do 150 x 12 which equels 1800

then add how muh shes saved and thats will be your total.
