Explain how to find the quotient of 1/4 divided by 5

Answers

Answer:

1/20

Step-by-step explanation:

(1/4) / 5

When dividing a fraction by a whole number

multiply the divisor by the number

4 * 5 = 20

(1/4) / 5 = 1/20

Answer:

Convert 1/4 to decimal form, which is 0.25.Divide 0.25 by 5 The quotient is 0.05, or 1/20 in simplified fraction form

There is another way to solve without converting:

Set up equation like this: 1/4 x 1/5 (Use KCF if you know how to divide or multiply by fractions. If you don't, use the first method above)1/4 x 1/5 = 1/20The quotient is 1/20

Solve these simultaneous equations. Use any method you want
2x+y=22
X-y=5

Answers

Answer:

by using substuton method

2x=22-y

x=22-y/2                     equation (i)

so substuting the value x in x-y=5

22-y/2-y=5

22-y-2y/2=5

22-3y=10

22-10/3=y

12/3=y

4=y

now substitute the value of y in equation (i)

x=22-y/2

=22-4/2

=18/2

=9

therefore ,the value of x is 9 and y is 4

A track is 400 yards around how many full laps does tyler need to run if he wants to run atleast 2 milies

Answers

Answer:

17.6 laps

Step-by-step explanation:

Total distance to be covered = 2 miles

distance coved in each lap = 400 yards

We know that 1 mile = 1760 yards

therefore, 4 miles will make = 4×1760

= 7040 yards.

Number of laps to be taken

= Total distance to be covered ÷ distance coved in each lap

= 7040/400 = 17.6 laps

Therefore, it would take 17.6 laps to cover a distance of 4 miles if lap were 400 yards.

The ages of trees in a forest are normally distributed with a mean of 25 years and a standard deviation of 5 years.

Answers

Complete question is in comment section :

Answer:

68%

Step-by-step explanation:

Mean = 25

Standard deviation = 5

The percentage of trees between 20 and 30

20 trees = 1 standard deviation below the mean ; mean - 1(standard deviation)

25 - 5 = 20

30 trees = 1 standard deviation above the mean ;

Mean + 1(standard deviation) ;

25 + 5 = 30

This means, 20 and 30 lies ±1 standard deviation from the mean which according to the empirical rule is 68%

1. A light year is defined as the distance light travels in one year. A galaxy is about 150,000 light years wide. About how many kilometers wide is a galaxy if 1 light year is given below? * 9.46x10^{12}

Answers

Answer: 1.419 * 10¹⁸ km

Step-by-step explanation:

The galaxy in question is 150,000 light years wide.

If 1 km = 9.46 * 10¹² then the width of this galaxy in kilometers is:

= Distance in light years * Conversion factor of light years to kilometers

= 150,000 * 9.46 * 10¹²

= 1,419,000 * 10¹² km

= 1.419 * 10¹⁸ km
