since we know that 40% = $20. we can understand that 80% = $40. since books and savings combine to 40%. this means books and savings mean $20. now that we have found how much 80% of money she has. we can find the remaining. 100% - 80% = 20%. we can divide our ratio 40% = $20 by 2 too see how much money is 20%. in which is %10

now we add up and get $50 in total.

The list shows the value of five accessories that Mary purchased for her cell phone. 29, 15, 22, 52, 38 What is the mean absolute deviation of the numbers in the list?

Answers

Answer:

11.04

Step-by-step explanation:

Given the data:

29, 15, 22, 52, 38

The mean absolute deviation :

Mean, m = Σx / n

n = sample size = 5

29 + 15 + 22 + 52 + 38 = 156

Mean = 156 / 5 = 31.2

Mean absolute deviation (MAD):

Σ|x - m| / n

(|29 - 31.2| + |15 - 31.2| + |22 - 31.2| + |52 - 31.2| + |38 - 31.2|) / 5

(2.2 + 16.2 + 9.2 + 20.8 + 6.8) / 5

55.2 / 5

= 11.04

Jacey has 40 pizzas to sell in the concession stand at a basketball game . Each pizza has been cut into 8 slices of equivalent size. In the first hour, Jacey sold 16 3/8 pizzas . In the second hour , she sold 18 3/4 pizzas . How many pizzas does Jacey have left to sell?

Answers

40 pies * 8 slices = 320 total slices.

In 1 hour = 16 3/8 slices sold.
In 2nd hour = 18 3/4 slices

16 3/8 + 18 3/4

Find Lowest Common Denominator:

3/4 -> 4/8

16 3/8 + 18 4/8 = 32 7/8

320(total slices) -32 7/8(slices Janey sold)= 188 1/8 slices (leftover slices)

Answer: 188 1/8 slices left to sell.

Use the inequality 12​>6(12x​+2). Complete parts a and b.

Answers

Answer/ Step-by-step explanation:

12>6(12x+2)

Divide both sides by 6. Since 6 is positive, the inequality direction remains the same.

12/6 >12x+2

Divide 12 by 6 to get 2.

2>12x+2

Swap sides so that all variable terms are on the left hand side. This changes the sign direction.

12x+2<2

Subtract 2 from both sides.

12x<2−2

Subtract 2 from 2 to get 0.

12x<0

Product of two numbers is <0 if one is >0 and the other is <0. Since 12>0, x must be <0.

x<0

You meet two talking sea turtles. The sum of their ages is 388. The male turtle is 42 years older than the female. How old is the male

Answers

Answer:

the answer is b on plato

Step-by-step explanation

:

The age of the male sea turtle will be 215 years old.

What is the solution to the equation?

The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.

You meet two talking sea turtles. The sum of their ages is 388. The male turtle is 42 years older than the female.

Let x be the age of a male and y be the age of a female. Then the equations will be

x + y = 388       ...1

x = y + 42         ...2

From equations 1 and 2, then we have

y + 42 + y = 388

2y = 346

y = 173 years old

Then the value of x will be

x = 173 + 42

x = 215 years old

The age of the male sea turtle will be 215 years old.

More about the solution of the equation link is given below.

In a right triangle, if a = 8 and c = 17, what is the correct setup to find the value of b?

Answers

Answer:

b = 15

Step-by-step explanation:

Assuming that the question is referring c as the hypothenuse, the Pythegorean theorem states: [tex]a^2+b^2=c^2[/tex].

Thus, [tex]b=\sqrt{c^2-a^2}=\sqrt{17^2-8^2}=15[/tex].

So b is 15.

Answer: b = 15

Step-by-step explanation:

Here, we need to know the formula for the relationship between the three sides of the right triangle: a² + b² = c².

a and b are legsc is hypotenuse

--------------------------------------------------------------------

Given

a = 8

c = 17

Solve

a² + b² = c²

(8)² + b² = (17)²

64 + b² = 289

b² = 225

b = √225

b = 15

how many apples would be left?

Answers

Hello!

Lets tackle each section separately!

So Robin gives the first group [tex]\frac{1}{8}[/tex] of the apples.

To find how many apples that is in standard form, we divide 40 by 8.

40 ÷ 8 = 5.

So the first group ate 5 apples.

The second group ate 4 apples.

We do not have to calculate anything since it is already in standard form.

The third group ate 20% of the apples.

To find 20% of forty we can multiply 40 by 0.20, since 0.20 is the decimal equivalent of 20%.

40 × 0.20 = 8.

The last group of children ate 8 apples.

Now we add each groups apple intake together.

5 + 4 + 8 = 17.

Finally, we subtract 17 from 40.

40 - 17 = 23.

There were 23 apples left.

Probability mathematic

Answers

Answer:

1/9

Step-by-step explanation:

Probability  =  Expected outcome/Total outcome

From the given pi chart,

Total outcome = 360degrees (since the total angle in a circle is 360 degrees)

Since we to find the probability of scoring a 5, we can see that the angle when he scores a 5 is 40degrees, hence;

Expected outcome = 40degrees

Pr(scoring a 5) = 40/360

Pr(scoring a 5) = 1/9

Hence the probability of scoring a 5 is 1/9

Answer:

1/9

Step-by-step explanation:

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty.

Divide the number of events by the number of possible outcomes.
