A desk drawer contains 8 blue pens, 7 black pens, and 10 green pens. Lawrence will randomly choose one item from the drawer. What is the probability Lawrence will choose a green pen?

Answers

Answer: [tex]\dfrac{2}{5}[/tex]

Step-by-step explanation:

Given

A desk drawer has 8 blue, 7 black, and 10 green pens

The favorable chances of drawing a green pen are 10

Probability is given by the ratio of favorable outcomes to the total outcomes.

So, the probability of drawing a green pen is

[tex]\Rightarrow P=\dfrac{10}{8+7+10}\\\\\Rightarrow P=\dfrac{10}{25}\\\\\Rightarrow P=\dfrac{2}{5}[/tex]

Una mamá tiene el cuádruplo de la edad de su hijo, y dentro de 5 años, tendrá el triple de años que el. Indica que edad tienen ambos.

Answers

Answer:

The son age is 10 years

And, his mother age be 40 years

Step-by-step explanation:

Given that

The mother is four times the age of her son

And,  in 5 years, she will be three times as old as him

We need to find out the ages of both

Here we assume that the age of her son be x

So the mother age be 4x

Now in 5 years, her mother would be 3 times as old as his son

So,

4x + 5 = 3(x + 5)

4x + 5 = 3x + 15

x = 10

The son age is 10 years

And, his mother age be 40 years

Marie has a recipe that calla for 2 1/4 cups of flour for 3 dozen cookies. How much would show needs to make 60 cookies


A. 4 Cups
B. 3 3/4
C. 3 1/2
D. 3 1/3​

Answers

Answer:

3 3/4 cups flour

Step-by-step explanation:

If Marie needs 2.25 cups of flour for 36 dozen cookies, then our equations would be:

2.25f = 36

f         = 16

3.75f  = 60

Note:

Dozen = 12

3 dozen = 3 • 12 = 36

2 1/4 cups of flour = 36 cookies


Now let’s figure out how much flour Marie needs for 1 cookie:

2 1/4 divided by 36 = 1/16

She needs 1/16 cups of flower for 1 cookie.

Now we need to find out how much she needs to 60 cookies:

1/16 • 60 = 15/4 = 3 3/4

Your answer is B. 3 3/4

Write a system of equations to describe the situation below, solve using any method, and fill in the blanks. Clayton gets paid at home for doing extra chores. Last week, he did 4 loads of laundry and 5 loads of dishes, and his parents paid him $14. The week before, he finished 4 loads of laundry and 10 loads of dishes, earning a total of $24. How much does Clayton earn for completing each type of chore? Clayton earns $ per load of laundry and $ per load of dishes.

Answers

Answer:

$1.00 per load of laundry, $2.00 per load of dishes

Step-by-step explanation:

4($1.00) = $4

5($2.00) = $10

This equals $14, when he does 10 loads of dishes the number changes to $20 and by adding $20 to $4, that equals $24.

The answer is $1.00 per a load of laundry, $2.00 per load of dishes

What is an expression?

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Last week, he did 4 loads of laundry and 5 loads of dishes, and his parents paid him $14. The week before, he finished 4 loads of laundry and 10 loads of dishes, earning a total of $24.

Clayton's earnings will be calculated as,

4($1.00) = $4

5($2.00) = $10

This equals $14, when he does 10 loads of dishes the number changes to $20, and by adding $20 to $4, that equals $24.

The other legs of the right-angle triangle will be 12.23 units and 11.81 units.

What is trigonometry?

The connection between the lengths and angles of a triangular shape is the subject of trigonometry.

The right angle triangle is shown with the angle of 44° and the length of the hypotenuse is 17 units.

Then the measure of the length of x will be given by a cosine angle of 44°.

cos 44° = x / 17

x = 12.23 units

Then the measure of the length of y will be given by a sine angle of 44°.

sin 44° = y / 17

y = 11.81 units

Thus, the other legs of the right-angle triangle will be 12.23 units and 11.81 units.
