Answer:

142

Step-by-step explanation:

[tex]\frac{x+18}{5}=32[/tex]

Multiplying both sides by 5, you get:

x+18=160

Now, you can subtract 18 from both sides to get:

x=142

Hope this helps! Comment if this wasn't clear enough, or you need more explanation.

Answer: x=142

Step-by-step explanation:

x+18 / 5 = 32

first multiply both sides by 5

x + 18 = 160

then subtract 18 from both sides

x=142

Step-by-step explanation:

Given:

The set of numbers {1, 2, 3, 4, 5}

Affter that, we find the sum um of two distinct numbers selected randomly from the set above;

Therefore, we have the following number: 3,4,5,6,5,6,7,7,8,9

so we have x = {3,4,5,6,5,6,7,7,8,9 }

now we find P(x) of each number, we have n(S) = 10

x  3 4 5 6 7 8 9

P(x)  1/10 1/10 1/10 2/10 2/10 2/10 1/10

Hope it will find you well.

The probability distribution of a set gives the probabilities of possible outcomes of the set

The set of numbers is given as:

[tex]\mathbf{Set = \{1, 2, 3, 4, 5\}}[/tex]

Add two distinct numbers of the set.

The sum is as follows

[tex]\mathbf{1+2 =3}[/tex]

[tex]\mathbf{1+3=4}[/tex]

[tex]\mathbf{1+4=5}[/tex]

[tex]\mathbf{1+5=6}[/tex]

[tex]\mathbf{2+3=5}[/tex]

[tex]\mathbf{2+4=6}[/tex]

[tex]\mathbf{2+5=7}[/tex]

[tex]\mathbf{3+4=7}[/tex]

[tex]\mathbf{3+5=8}[/tex]

[tex]\mathbf{4+5 = 9}[/tex]

The sum of the distinct numbers are:

[tex]\mathbf{Sum = \{3,4,5,6,5,6,7,7,8,9\}}[/tex]

Calculate the probability of each number in the sum set i.e. 3, 4, 5, 6, 7, 8 and 9

[tex]\mathbf{P(3) = P(4) = P(5)= P(9)= \frac{1}{10} = 0.10}[/tex]

[tex]\mathbf{P(6) = P(7) = P(8)= \frac{2}{10} = 0.20}[/tex]

So, the probability distribution for the random variable is:

x   - - P(x)

3 -- 0.10

4 -- 0.10

5 -- 0.10

6 -- 0.20

7 -- 0.20

8 -- 0.20

9 -- 0.10

Answer:

2(4+x)

Step-by-step explanation:

"Twice the sum of" tells us it will be the equation times two

"the sum of four and a number" is easy, thats 4 + x

The second number is x because the number is not specified so we need a place holder, x in this case, to tell us that the number is not given.

All this put together = twice the sum of four and a number, or 2(4+x)

The expression for "twice the sum of four and a number" is represented by 2(x + 4) or 2 * (x + 4), signifying that you first sum the number with four and then double the result.

The expression that correctly represents "twice the sum of four and a number" is 2(x + 4) or 2 * (x + 4), where x is the variable representing the unknown number. To arrive at this expression, you first find the sum of four and the number (x + 4) and then multiply the result by two to get twice this sum.

In this context, the word 'twice' is similar to triple as in triple the amount of money being three times as much. This operation is an example of simple addition, much like when two numbers are added in any order, such as 2 + 3 or 3 + 2, which illustrates the commutative property of addition.

Answer:

B (V = 4500π ft3; S = 900π ft2)

Step-by-step explanation:

If the great circle's area is 225pi, that makes the radius sqrt225 = 15

The volume of a sphere is (4/3) pi r^3, so the volume would be 3375 * 4/3 pi= 4500pi

The surface area of a sphere is 4 pi r^2, so the Surface area would be 4 * 225 pi = 900pi

That makes the answer B (V = 4500π ft3; S = 900π ft2)

Answer:

Alvin can't have more than 2 fishes on his tank.

Step-by-step explanation:

In order to calculate how many fish Alvin can have in his tank we first need to calculate the volume of the tank. A prism's volume is given by the following formula:

v = Abase*h

Therefore for Alvin's, we have:

v = 0.9*0.6 = 0.54 m³

Since he can't have more than 5 fish per cubic meter we can use a rule of three in a way that:

5 fish -> 1 m³

x fish -> 0.54 m³

5/x = 1/0.54

x = 0.54*5 = 2.7

Since he can't have a 0.7 fish and in order to mantain the density to the recommended level, he can't have more than 2 fishes.

The Length of the large rectangle is 2 units.

It is required to find the length of the large rectangle.

A rectangle is a type of quadrilateral, whose opposite sides are equal and parallel. It is a four-sided polygon that has four angles, equal to 90 degrees. A rectangle is a two-dimensional shape.

Given:

A rectangle is 2 inches wide, and more than 2 inches long.

According to given question we have,

Ratio of width to length of known rectangle is 2:4 this simplifies to 1:2

The smaller similar rectangle will have the same ratio. .i.e. 1:2

Since the width is 1 then the length will be 2.

.This can also be looked at another way. the second value in the ratio is

2:1 of the first value in the ratio and the first value is 1:2 of the second value.

So, Length of the large rectangle is 2 units.

Width of the large rectangle is 1 units.

Therefore, the Length of the large rectangle is 2 units.

Answer:

The answer to your question is 56 gal

Step-by-step explanation:

Data

Percent filled = 95%

Total water can hold = 1120 gal

remaining water = ?

Process

1.- Calculate the 95% of 1120 gal

              1120 gal ------------------ 100%

                x           ------------------   95%

                      x = (95 x 1120) / 100

                      x = 106400 / 100

                      x = 1064 gal

2.- Calculate the remaining water by subtracting the previuos value to the total capacity.

Remaining water = 1120 - 1064

Answer: The number of calories increased by 20%.

Step-by-step explanation:

Given : The doctor recommended that Mike increase the number of calories he burns working out from 1,500 to 1,800.

Previous number of calories he used to burn = 1,500

Increase in calories = 1800-1500=300

Now , the percent increase in calories = [tex]\dfrac{\text{Increase in calories}}{\text{previous calories}}\times100[/tex]

[tex]=\dfrac{300}{1500}\times100=20\%[/tex]

Answer:

15 years old

Step-by-step explanation:

Let's say Amanda's age is a, Brantley's age is b, and Carlos's age is c.

"Amanda is 3 years older than Brantley" means that a = 3 + b

"Carlos is twice as old as Amanda" means that c = 2 * a = 2a

"The sum of their ages is 57" means a + b + c = 57

We know that a = 3 + b, which can be written as b = a - 3. Substitute a - 3 in for b and 2a in for c in the equation a + b + c = 57 so that we have one variable to solve for:

a + b + c = 57

a + (a - 3) + 2a = 57

4a - 3 = 57

4a = 60

a = 15

Amanda is 15 years old.

Answer:

15

Step-by-step explanation:

A = B + 3

B = A - 3

C = 2A

A + B + C = 57

A + A - 3 + 2A = 57

4A - 3 = 57

4A = 60

A = 15

Total for the week T;

T = 20/3 + 3/6 = 40/6 + 3/6 = 43/6 miles

T = 7.17 miles

Step-by-step explanation:

Given;

Michael walks his black lab 1 2/3 miles on Mondays, Wednesday's, Friday's, and Sunday's.

On four days = 1 2/3 = 5/3 miles per day

Total for the 4 days = 4 × 5/3 = 20/3 miles

He walks his poodle 1/6 of a mile on Tuesdays, Thursdays, and Saturdays

On 3 days = 1/6 miles per day

Total for the 3 days = 3 × 1/6 = 3/6 miles

Total for the week T;

T = 20/3 + 3/6 = 40/6 + 3/6 = 43/6 miles

T = 7.17 miles

Answer:

he saved $40

Step-by-step explanation:

The required money saved by spencer at the end of the summer sale is $40.98.

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

Here,
Spencer picked out a remote–control car on sale for 20% off the original price of $79.99.
He also picked out a robot for 25% off the original price of $99.99.

Money saved by spencer = 0.2 × 79.99 + 0.25 × 99.99
                                       = 15.99 + 24.99
                                       = $40.98

AB = 23.4 inches

Step-by-step explanation:

If the diameter of the wheel is 25 inches, we have that its radius is 25/2 = 12.5 inches.

If we draw a radius to the bottom of the wheel and a radius to point A, we have a triangle where we can use Pythagoras' formula:

(see image attached for better understanding)

r^2 = (r-8.1)^2 + (AB/2)^2

12.5^2 = 4.4^2 + AB^2/4

156.25 = 19.36 + AB^2/4

AB^2/4 = 136.89

AB^2 = 547.56

AB = 23.4 inches

Step-by-step explanation:

n(AUB) = n(A) + n(B) - n(AnB )

= 240 + 160 - n(A n B)

= 400 - n(AnB )

Since n(AnB) 20, so n(AUB) S 400

But n(U) = 360, so n(A U B)* 360

.. the maximum value of n(AUB) = 360.

When n(A U B) is maximum, n(AnB) will be minimum.

.. min. value of n(An B)

= n(A) + n(B) - Max, value of n(AUB)

= 240 - 160 - 360 = 40

Again, n(
