Answer:

Step-by-step explanation:

s(20/100)=40

20s=4000

s=200

So there are a total of 200 students.

Answer:

There are 200 middle school students

Step-by-step explanation:

The equation for this question can be: 40 is 20% of what. This can be simplified to 40 = 0.2x and then to get x by itself you divide 40 by 0.2 which is 200.

Answer:Yes, your answers are correct.

The volume of a cone is given by V = 1/3πr²h.  Since the diameter of the first cone is 4, the radius is 2; therefore the volume is

V = 1/3π(2²)(8) = 32π/3

We divide the volume of the sink, 2000π/3, by the volume of the cone:

2000π/3 ÷ 32π/3 = 2000π/3 × 3/32π = 6000π/96π = 62.5 ≈ 63.

The diameter of the second conical cup is 8, so the radius is 4.  The volume then is:

V = 1/3π(4²)(8) = 128π/3

Dividing the volume of the sink, 2000π/3, by 128π/3:

2000π/3 ÷ 128π/3 = 2000π/3 × 3/128π = 6000π/384π = 15.625 ≈ 16

Answer:

#8 - 52°, #9 - 29°

Step-by-step explanation:

8. The two angles added together are a straight line, so they sum up to 180 degrees.

x + (2x + 24°) = 3x + 24° = 180°

3x + 24° = 180°

3x = 156°

x = 52°

9. Similar to #8. "Supplementary" means they add up to 180° (whether they are actually next to each other or not).

So,     4x + (2x + 6°) = 180°

                 6x + 6° = 180°

                     6x = 174°

                        x = 29°

Answer:

264

Step-by-step explanation:

3 + 8 = 11

3 - 1 = 2

3 - 1 = 2

2 + 4 = 6

11 x 2 x 2 x 6 = 264

Answer: 3 mph

Step-by-step explanation:

1. 1/2 mph for 1/2 an hour as they said, meaning that they would've walked for 3 miles kn an hour.

2. 4 and 1/2 miles.

3 + 1 2/4. = 4 1/2

3. 1 3/4 hours.

3 + 2.25 = 5.25

3 x .75 = 2.25

3 miles per hour.

Answer:

[tex]P(X = x) = \frac{2^{3-x}}{27}[/tex]

Step-by-step explanation:

Given

[tex]Black = 4[/tex]

[tex]Green = 2[/tex]

[tex]r = 3[/tex] --- selected balls (with replacement)

Required

Determine the probability distribution for the green balls.

Let x be a [tex]random\ variable[/tex] such that:

[tex]x = 0, 1, 2, 3[/tex]

Because it is a selection with replacement

The probability of a green ball being drawn is always:

[tex]P(G) = \frac{Green}{Total}[/tex]

[tex]P(G) = \frac{2}{6}[/tex]

[tex]P(G) = \frac{1}{3}[/tex]

The probability of a black ball being drawn is always:

[tex]P(B) = \frac{Black}{Total}[/tex]

[tex]P(B) = \frac{4}{6}[/tex]

[tex]P(B) = \frac{2}{3}[/tex]

So, the probability distribution of green is:

[tex]P(X = x) = (P(B))^{3-x} * (P(G))^x[/tex]

[tex]P(X = x) = (\frac{2}{3})^{3-x} * (\frac{1}{3})^x[/tex]

Apply law of indices

[tex]P(X = x) = \frac{2^{3-x}}{3^{3-x}} * \frac{1^x}{3^x}[/tex]

[tex]P(X = x) = \frac{2^{3-x}*1^x}{3^{3-x}*3^x}[/tex]

[tex]P(X = x) = \frac{2^{3-x}*1}{3^{3-x+x}}[/tex]

[tex]P(X = x) = \frac{2^{3-x}*1}{3^3}[/tex]

[tex]P(X = x) = \frac{2^{3-x}}{27}[/tex]

Answer:

f=-15

Step-by-step explanation:

Let's solve your equation step-by-step.

f /3 +22=17

Step 1: Simplify both sides of the equation.

1 /3 f+22=17

Step 2: Subtract 22 from both sides.

1/ 3 f+22−22=17−22

1/3f=-5

Step 3: Multiply both sides by 3.

3*(1/3f)=(3)*(-5)

f=−15

Answer:

f=−15

The value of the variable f for the given expression is f=-15.

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.

Given that the expression is f/3+22=17. The value of f will be calculated as:-

f /3 +22=17

Step 1: Simplify both sides of the equation.

1 /3 f+22=17

Step 2: Subtract 22 from both sides.

1/ 3 f+22−22=17−22

1/3f=-5

Step 3: Multiply both sides by 3.

3*(1/3f)=(3)*(-5)

f=−15

Hence, the value of f will be -15.

x = 138 650.3067

x = 138 650 (to the nearest whole number)

Answer:

x = 20

Step-by-step explanation:

5x - 21 = 2x + 39 (corresponding angles are congruent)

Collect like terms

5x - 2x = 21 + 39

3x = 60

Divide both sides by 3

3x/3 = 60/3

Answer:

( 2 , 2 )

Step-by-step explanation:

Solve the eqaution :

3x +2y=10

4x-y=6

Solve the eqaution for y :

3x + 2y = 10

y = -6 + 4x

Substitute for y : 3x + 2 ( -6 + 4x ) = 10

x = 10

Substitute for the value of x : x = 2

Substitute the given value of x into the eqaution

y = -6 + 4x : y = -6 + 4 × 2

Solve the eqaution: y = -6 + 4 × 2

solve the eqaution for y : y = 2

y = 2 A possible solution : the ordered solution pair is
