Compare the size of 1 meter to the size of 1 centimeter. use your meterstick to help.

1 answer:

4 0

This seems like a simple conversion problem. 1m=?cm and 1cm=?m.

Since this uses the metric system, you know the general layout of the prefixes: K H D M d c m. I remember this as King Henry died Monday drinking chocolate milk, but as long as you remember it you're good.

Let's look at 1m. Centimeters is two places away from it
K H D (M) d (c) m
This means you move the decimal place to the right two times, so 1 meter is equal to 100 centimeters.

For 1 cm, the meter position is two places away. This means we have to move the decimal place to the left two times. So, 1 centimeter is equal to 0.01 meters.

7over10 subtract 5over12 in simplest form

Andrews [41]

Answer: $=\frac{17}{60}\quad \left(\mathrm{Decimal:\quad }\:0.28333\dots \right)$

Step-by-step explanation:

$\left(\frac{7}{10}\right)-\left(\frac{5}{12}\right)$

$=\frac{7}{10}-\frac{5}{12}$

$=\frac{42}{60}-\frac{25}{60}$

$=\frac{42-25}{60}$

$=\frac{17}{60}$

A bus travels with a constant speed of 48 miles per hour. How long will it take to travel 60 miles?

andre [41]

Answer:

A bus travels with a constant speed of 48 miles per hour. How long will it take to travel 60 miles?

Step-by-step explanation:

Mostly it's 1.25 hours </3 Since distance = rate times , or d = rt, then we have

t = d/r = 60 miles / 48 mph = 1.25 hours = 1 hour 15 minutes

either 1 hour 15 mins or 1hour and 25 mins.

The larger of two numbers is twice the smaller increased by five. Find the two numbers if three times the larger exceeds double

irina [24]

The larger number is 13 and smaller number is 4

<em><u>Solution:</u></em>

Let the larger number be "a"

Let the smaller number be "b"

<em><u>Given that larger of two numbers is twice the smaller increased by five</u></em>

larger number = twice the smaller increased by five

larger number = twice the smaller number + 5

a = 2b + 5 --- eqn 1

<em><u>Also given that three times the larger exceeds double the smaller by 31</u></em>

Here "exceeds" denotes addition and "times" denotes multiplication

"double" denotes being multiplied by 2

three times the larger number = double the smaller number + 31

3a = 2b + 31 ---- eqn 2

<em><u>Let us solve eqn 1 and eqn 2 to find values of "a" and "b"</u></em>

Substitute eqn 1 in eqn 2

3(2b + 5) = 2b + 31

6b + 15 = 2b + 31

6b - 2b = 31 - 15

4b = 16

From eqn 1,

a = 2b + 5

a = 2(4) + 5

a = 8 + 5

Thus the larger number is 13 and smaller number is 4

What price do farmers get for the peach crops? in the third week of June, a random sample of 40 farming regions gave a sample me

prohojiy [21]

Given:
Sample size, n = 40
Sample mean, xb = $6.88
Population std. deviation, σ = $1.92 (known)
Confidence interval = 90%

Assume normal distribution for the population.
The confidence interval is
(xb + 1.645*(σ/√n), xb - 1.645*(σ/√n)
= (6.88 + (1.645*1.92)/√40, 6.88 - (1.645*1.92)/√40)
= (7.38, 6.38)

Answer: The 90% confidence interval is (7.38, 6.38)
