Norma has 10 black,12 white,and 3 brown pairs of socks in one drawer. What is the probability that without looking, Norma will pick a BROWN pair of socks from the drawer?

Answers

Answer:

1/100.

Step-by-step explanation:

Total number of socks in the drawer

= 25.

Prob(First pick is brown) = 3/25.

Prob(Second pick is brown) = 2/24 = 1/12.

So the required probability

= 3/25 * 1/12

= 3/300

= 1/100.

Answer:

Ok so the answer to this question would be 3/25

Step-by-step explanation:

The answer to the probability is always a fraction

The numerator is the number of favorable outcomes - in this problem, it is the brown socks

The denominator is the total amount of possible outcomes - in this problem, it is the total amount of socks

3/ 10+ 12 +3 = 3/25

- By the way, have your answer in simplest form - always

Great-Grandma celebrated her eighty-fourth birthday in 2002. In what year was she born?

Answers

Answer:

1918

Step-by-step explanation:

Great-Grandma celebrated her eighty-fourth birthday in 2002. In what year was she born?

2002 - 84 years = 1918

________________________________________________

This follows the same principal as you subtracting your age from the current year to find the year in which you were born.

Answer:

Celebration of 84 birthday = 2002

Year in which she was born = 2002 - 84

                                               =1918

Therefore Great-Grandma was born on the year 1918

Directions: Follow the instructions for the following inequalities.


1. 4 < 7 Multiply both sides by 3, then by 2, then by 4, then by 9


2. 11 > -2 Add 3 to both sides, then add 3, then add (-4)


3. -2 less than or equal to -2 Subtract 6 from both sides, then 8, and then 2


4. -4 < 8 Divide both sides by -4, then by -2


5. Write a short explanation of the effects of the above operations. Did this affect the inequality sign? Was it still true? Why or why not?

Answers

Answer:

1. 504 < 1512

2. 12 > 0

3. -2 = -2

4. -1 < 2

Step-by-step explanation:

Given that both sides are being changed by the same amount and sign, the sign never changes. They always have the same value.

The answer is -2 because after you multiply you have to divide

Answers

Answer:

313 square feet

Step-by-step explanation:

313 square feet

Answer:

A) 25

Step-by-step explanation:

sides of top square are all 13 and sides of bottom square are all 12

we now have the hypotenuse (13) and another side length of the triangle (12) using a^2+b^2=c^2 we can find the side of the square then its area.

144+b^2=169

b^2=25

b=5, which means the smallest square's sides are all 5 making it have an area of 25

These taxes are withheld to fund various government programs and services.

Payroll taxes typically include federal, state, and local income taxes, as well as Social Security and Medicare taxes.

The amount of payroll taxes deducted from an employee's paycheck depends on factors such as income level, tax brackets, and the tax rates set by the applicable government authorities.

Original number of students: 56
New number of students: 77
Find the percent of change. Round your answer to the nearest tenth of a percent, if necessary.

Answers

Answer:Therefore, the percent change from 56 to 77 students is 37.5%.

Step-by-step explanation:

students, we can use the following formula:

percent change = ((new number - old number) / old number) x 100%

Plugging in the values given in the problem, we get:

percent change = ((77 - 56) / 56) x 100%

percent change = (21 / 56) x 100%

percent change = 0.375 x 100%

percent change = 37.5%

Therefore, the percent change from 56 to 77 students is 37.5%.

How does the speed of the cart depend on the time it take the car to reach 100 cm?

Answers

The speed of the cart affects how long it takes to reach 100 cm. For example, if the cart traveled 10 cm in a minute, it would be a bit long and take 10 mins. But if the cart traveled 100 cm in a minute, it could get there in less time and be better and faster.
The speed depends on how fast or how slow the cart will go, so if you push the cart slowly then it will either take a long time to reach 100cm or it will stop before it reaches where it needs to be because it wasn’t enough energy put towards the push, but on the hand, if you were to push it with the right amount of force then it would be able to reach 100cm or better.

Answer:

Explanation:

three-fifths of 61.5 is 36.9!

Answer:

D. 36.9

Step-by-step explanation:

The total amount of gallons the gardener typically uses in a month is 61.5 gallons. Since the gardener used 3/5 gallons, we know that 5/5 is 61.5 gallons. So you would have to divide 61.5 by 5 in order to get 1/5 of the gallons which would be 12.3. Then you have to multiply the 12.3 by 3 in order to get 3/5 of how much the gardener used which is 39.9 gallons. I hope this helped!

Expand the expression -12(4c - 3d) using the Distributive Property

Answers

Answer:

-48c - 37d

Step-by-step explanation:

Multiply both numbers by -12.

The expanded form of the expression is -48c+36d

What is Distributive Property?

According to this property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.

Given that, we have to expand the expression -12(4c - 3d) using the Distributive Property,

We know that the rule for distributive property is :

a(b+c) = ab+ac

Therefore,

-12(4c - 3d)

= -12(4c)+12(3c)

= -48c+36d

Hence, the expanded form of the expression is -48c+36d
