Answer: 1/6

Step-by-step explanation:

Red pens = 3

Green pens = 2

Blue pen = 1

Total = 3+2+1 = 6

Probability of picking a red pen = 3/6 = 1/2

Probability of picking a green pen = 2/6 = 1/3

The probability of picking a red pen, replacing it, and then picking a green pen will be calculated as:

= 1/2 × 1/3

= 1/6

Answer:

-13x + 21

Step-by-step explanation:

12+5x-18x+9

Like terms: 5x, -18x and 12, 9

Add like terms: 5x + -18x = -13x, 12 + 9 = 21

12 + 5x - 18x + 9 = -13x + 21

I hope this helps :D

Answer:

1

Step-by-step explanation:

2x + 3 = 5

Subtract 3 on both sides to get the different values (variables, and numbers without variables) seperated.

2x + 3 - 3 = 5 - 3

2x = 2

Divide by 2 on both sides to isolate the variable

2x/2 = 2/2

x = 1

Check

Now that you have what "x" is (1) you can substitute that into the equation

2x + 3 = 5

2(1) + 3 = 5

2 + 3 = 5

5 = 5 CORRECT

Hope this helped!

Answer:

400 small boxes

Step-by-step explanation:

125 boxes would contain : 125 x 48 = 6000 tins

the number of small boxes needed to contain 6000 tins = 6000 / 15 = 400 small boxes

Answer:

R = 8,228,571.43 (Approx)

Step-by-step explanation:

Given:

R = x²/y

x = 4.8 x 10⁵

y = 2.8 x 10⁴

Find:

Value of R

Computation:

R = x²/y

R = (4.8 x 10⁵)²/ (2.8 x 10⁴)

R = 23.04 x 10¹⁰ / (2.8 x 10⁴)

R = 8.22857.. x 10⁶

R = 8,228,571.43 (Approx)

Answer:

Height of rectangular prism = 11 inches

Step-by-step explanation:

Given that:

Volume of rectangular prism = 572 cubic inches

Length of prism = 4 inches

Width of prism = 13 inches

Volume of prism = Length * Width * Height

572 = 4 * 13 * h

572 = 52h

52h = 572

Dividing both sides by 52

[tex]\frac{52h}{52}=\frac{572}{52}\\h=11[/tex]

Hence,

Height of rectangular prism = 11 inches

Answer:

82

Step-by-step explanation:

if 3n-8 = the formula then you replace n with 30 to get the 30th term

so type into your calculator 3(30)-8 and you get 82

Answer:

D

Step-by-step explanation:

Answer:

child tickets: 115

adult tickets: 175

Step-by-step explanation:

number of child tickets = x

number of adult tickets = y

(value of child ticket [8] * number of child tickets [x]) + (value of adult ticket [8.5] * number of adult ticket [y]) = total value (2407.50)

8x + 8.5y= 2407.50

290 (total number of tickets) = x (number of child tickets) + y (number of adult tickets)

290 = x+y

system of equations: 8x + 8.5y= 2407.50

290 = x + y

solve equation:

x = 115

y = 175

Answer:

i. 4 two-point shots

ii. 10 free throws

Step-by-step explanation:

Number of times scored = 14

total points made = 18

let her two-point shot be represented by x, and her free throw by y.

So that;

x + y = 14 .......... 1

But, two points for each two-point shot and one point for each free throw;

2x + y = 18 ......... 2

Subtract equation 2 from 1

2x - x + y - y = 18 - 14

x = 4

substitute the value of x in equation 1

4 + y = 14

y = 14 - 4

y = 10

x= 4, y = 10

Thus, she made 4 two-point shots, and 10 free throws.

Answer:

4 two-pointers and 10 free throws

Step-by-step explanation:

18 - 14 = 4

4 two-pointers = 8

10 free throws = 10 points

Answer:

Both angles have a measure of 73 degrees

Step-by-step explanation:

5x+28=4x+37

x+28=37

x=9

(5(9)+28)                     (4(9)+37)

(45+28)                       (36+37)

(73)                               (73)

Answer:

Angle J is 58

Both Angle L and K are 61

Step-by-step explanation:

Since it's an isosceles triangle, it means the base angles are equivalent. In this case, both base angles are 4x + 37

Add all the angles (combine like-terms):

(4x + 37) + (4x + 37) + (5x + 28) = 13x + 102

All the angles of a triangle always sums up to 180 degrees.

13x + 102 = 180

       -102    -102

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

13x = 78

x = 6

Now that you've found x, substitute into the equation for each angle.

Answer is B.

Answer:

it is a direct proportion

The constant of proportionality is 0.4

Step-by-step explanation:

0.4 Y = X

Direct proportion can be written as

x = ky

Where,

k = constant of proportionality

0.4 Y = X can also be written as

x = 0.4y it is a direct proportion

The constant of proportionality is 0.4

Answer:

-25 percent well I think this is the way I do it

Answer:

For 11, x=18

Step-by-step explanation:

Use a ratio to solve for x since the triangles are similar

16/20=(16+12)/(20+x-3), first simplify both sides

4/5=28/(17+x), cross multiply

4(17+x)=5*28

17+x=5*7

x=35-16

x=18

Step-by-step explanation:

Increase the number by 5% of its value.

Percentage increase = 5% × 220

New value =

220 + Percentage increase =

220 + (5% × 220) =

220 + 5% × 220 =

(1 + 5%) × 220 =

(100% + 5%) × 220 =

105% × 220 =

105 ÷ 100 × 220 =

105 × 220 ÷ 100 =

23,100 ÷ 100 =

231
