class starts at 8:30. it takes max 25 minutes to bicycle to school. at what time should he get to school if he wants to go 15 minutes early

Answers

Answer 1

Answer: Since class starts at 8:30, you would subtract 15 from 8:30 (Because he wants to be 15 minutes early)

It takes him 25 minutes to bike to school, and 8:15 -:25 is 7:50.

You can come to this conclusion by adding the two times, and subtracting them from 8:30 as well!

Answer 2

Answer:

Answer:

He'd have to leave his house at 7:50

Step-by-step explanation:

If class starts at 8:30 and it would take him 25 minutes to get there, you could start out by subtracting 25 from 30 which would mean that he would usually have to leave at 8:05, and then subtract 15 from that to get 7:50, or you could add 25 and 15 together and subtract that from 8:30 to get 7:50.

What is bigger, 4,000,000 mm or 4km

Answers

4,000,000 mm is equal to 4 km

4,000,000 mm = 4 km

We need to have the same unit to compare.

We can change km to mm

1 km is 1,000,000 mm so,
4 km is 4,000,000 mm

4,000,000 mm = 4,000,000 mm
Both are equal

Antonia is keeping track of the number of pages she reads. She started the school year having already read 95 pages her book, and she then reads 20 pages each day. The function for her total pages read is f(x) = 20x + 95. What do f(x) and x represent in Antonia's situation?1. f(x) represents the number of days; x represents the total number of pages that Antonia has read
2. f(x) represents the total number of pages that Antonia has read; x represents the number of days
3. f(x) represents the number of pages Antonia reads per day; x represents the number of days
4. f(x) represents the total number of pages that Antonia has read; x represents the number of pages she reads per day

Answers

20 pages per day
so the variable attached to the number 20 would be "number of days"
so x represents the number of days

then 90 + 20(number of days) = (total number of pages)
so that makes f(x) = (total number of pages)

therefore your answer is 2.

Answer:

Option 2. f(x) represents the total number of pages that Antonia has read; x represents the number of days

If one woman is selected find the probability that her height is less than 65 inch with a mean of 64.4 and standard deviations of 1.8

Answers

The probability of one woman to have height less than 64.4 in is 0.6293

Explanation:

Given:

Mean, μ = 64.4

Standard deviation, δ = 1.8

Probability that the height of the woman is less than 65 inch = ?

So,

P(x < 65) = 65 - μ / δ

$=(65 - 64.4)/(1.8)\n \n= 0.33$

P (x < 65) = P( z < 0.33)

Finding the probability value from the z table we get:

P( z < 0.33) = 0.6293

Therefore, the probability of one woman to have height less than 64.4 in is 0.6293

What is the balance on a deposit of $1,150 that earns 9% interest compounded annually for 2 years

McDonald's has sold more than a billion hamburgers. If it were possible to eat a hamburger every minute of every day without stopping, how many years would it take to eat a billion hamburgers

Answers

Generically, you're asking how many years make 1 billion minutes.

(1 x 10⁹ minutes) x (1hr/60min) x (1 da/24hr) x (1yr/365.25da) =

(1 x 10⁹) / (60 x 24 x 365.25) years = 1,901.3 years (rounded)

1 day = 24 hours
24 hours =1440 minutes

1 year = 365 days
365 x 1,440 = 525, 600 minutes per year.

it means, 525600 hamburger per year

the area of a rectangle is 100 Sq inches. the perimeter of the rectangle is 40 inches. a second rectangle has the same area but a different perimeter. is the second rectangle a square? explain why or why not.

Answers

A rectangle with an area of 100 square inches and a perimeter of 40 feet must have sides of 10 feet each, making it a square. A rectangle with the same area and any other perimeter would therefore not be a square.
