Answer:

20 is to 56 as 3 is to x

20x= 8.2

Answer:

225

Step-by-step explanation:

√x - 3 + 12 = 24

√x + 9 =24

√x = 24 - 9

√x = 15

Squaring on both sides,

( √x )^2 = 15^2

x = 225

Answer:

x=225

Step-by-step explanation:

√x-3+12=24

Combine -3 and 12

√x+9=24

Subtract 9 from 24

√x=15

Now do the opposite of a square root to the other side to remove the square root from the x

x=15^2

x=225

Answer:

yes

Step-by-step explanation:

side 5 and side 12 where the angle is you can form a square in the corner

Answer:

a)

Sample Space of Probability model is - S' = { [tex]\frac{1}{4}[/tex] , [tex]\frac{1}{4}[/tex] , [tex]\frac{1}{4}[/tex] , [tex]\frac{1}{4}[/tex] }

b)

Probability of Event 1 , P(1) = [tex]\frac{2}{8} = \frac{1}{4}[/tex]

Probability of Event 2 , P(2) = [tex]\frac{2}{8} = \frac{1}{4}[/tex]

Probability of Event 3 , P(3) = [tex]\frac{2}{8} = \frac{1}{4}[/tex]

Probability of Event 4 , P(4) = [tex]\frac{2}{8} = \frac{1}{4}[/tex]

Step-by-step explanation:

Given - Murray spins the pointer of the spinner as shown .

To find - a. What is the sample space for the probability model?

              b. What is the probability of each event in the sample space?

Proof -

The Sample space is the set of all possible outcomes.

So,

Sample space becomes -

S = { 3, 5, A, Y, 3, 5, A, Y}

Total number of outcomes, n(S) = 8

Now,

We can see that There are 4 types of event

Event 1 : 3

Event 2 : 5

Event 3 : A

Event 4 : Y

So,

Probability of Event 1 , P(1) = [tex]\frac{2}{8} = \frac{1}{4}[/tex]

Probability of Event 2 , P(2) = [tex]\frac{2}{8} = \frac{1}{4}[/tex]

Probability of Event 3 , P(3) = [tex]\frac{2}{8} = \frac{1}{4}[/tex]

Probability of Event 4 , P(4) = [tex]\frac{2}{8} = \frac{1}{4}[/tex]

Now,

Sample Space of Probability model is -

S' = { [tex]\frac{1}{4}[/tex] , [tex]\frac{1}{4}[/tex] , [tex]\frac{1}{4}[/tex] , [tex]\frac{1}{4}[/tex] }

∴ we get

a)

Sample Space of Probability model is - S' = { [tex]\frac{1}{4}[/tex] , [tex]\frac{1}{4}[/tex] , [tex]\frac{1}{4}[/tex] , [tex]\frac{1}{4}[/tex] }

b)

Probability of Event 1 , P(1) = [tex]\frac{2}{8} = \frac{1}{4}[/tex]

Probability of Event 2 , P(2) = [tex]\frac{2}{8} = \frac{1}{4}[/tex]

Probability of Event 3 , P(3) = [tex]\frac{2}{8} = \frac{1}{4}[/tex]

Probability of Event 4 , P(4) = [tex]\frac{2}{8} = \frac{1}{4}[/tex]

Answer:

25.12 in³

Step-by-step explanation:

v = (1/3)πr²h

Plug in the givens

v = (1/3)(3.14)(4/2)²(6)

v = (1/3)(3.14)(4)(6)

v = 25.12

Answer:

591.5 [tex]ft^{3}[/tex]

Step-by-step explanation:

Volume = length x width x height

Length = 13 ft. Because it is the same size has the height

Width = 7 ft.

Height = 13 ft.

13ft x 13ft x 7ft = 1,183 ft

BUT, that can't be the answer because we're solving a prism

So divide the volume.

1,183 divided by 2 equals 591.5

Answer:

132 cm^2

Step-by-step explanation:

Area of trapezoid = 1/2 ( (7 + 19) * 8) = 26*4 = 104 cm^2

Area of rectangle = 4 x 7 = 28 cm^2

104 cm^2 + 28 cm^2 = 132 cm^2

▬▬▬▬▬▬▬▬▬▬▬▬▬▬

→ Base = 15 and 10

→ Height = 12

→ Area of trapezoid

→ Area of Trapezoid = (a + b)/2 × h

= (15 + 10)/2 × 12

= 150 ft²

∴ The area of Trapezoid is 150 ft²

Answer:

There are 406 students in the school

Step-by-step explanation:

Let the number of students in the school be x

The total ratio is 11 + 3 = 14

The ratio that buys lunch is represented by 3

So, we have it that;

3/14 * x = 87

3x = (14 * 87)

x = (14 * 87)/3

x = 406

Answer:

Since a fraction represents a division, we should do that division to know what the value of a fraction is. The larger numerator, the larger the value of the fraction will be; and the larger denominator, the smaller the fraction will be. ...

Answer:

cos(71)

Step-by-step explanation:

Since 19° is less than 90, we can express this in terms of confunction.

sin(θ) = cos(90-θ)

sin(19) = cos(90-19)

sin(19) = cos(71)

Answer:

(x + 5)**2 + (y + 2)**2 = 25

Step-by-step explanation:

We know that the general equation for a circle is ( x - h )^2 + ( y - k )^2 = r^2, where ( h, k ) is the center and r is the radius. The graph shows the center at (-5, -2), and the radius of 5. So plugging this in

(x - -5)**2 + (y - - 2)**2 = 5**2

(x + 5)**2 + (y + 2)**2 = 25

Answer:

P(x)= x ^4-3x^3+x^2-4    

Step-by-step explanation:

Given data

R(x) = 2x ^4-3x^3+2x-1

c(x)=x^4-x^2+2x+3

We know that

P(x)=R(x)-C(x)

Hence

P(x)= 2x ^4-3x^3+2x-1-(x^4-x^2+2x+3)

open bracket

P(x)= 2x ^4-3x^3+2x-1-x^4+x^2-2x-3

Collect like terms

P(x)= 2x ^4-x^4-3x^3+x^2-2x+2x-3-1    

P(x)= x ^4-3x^3+x^2-4

Answer:

3 1/3 miles per hour

Step-by-step explanation:

(5/2 ÷ 3/4) = (s ÷1)

(5/2 ÷ 3/4) = 10/3

10/3 = s/1

cross-multiply:

3s = 10

s = 10/3

s = 3 1/3 miles per hour
