Taylor had a bag of 28 marbles. 5 red, 9 blue, 8 yellow, and 6 black. If Taylor pulled out a yellow one and DID NOT put it back in. What is the
probability of pulling out a blue marble (SIMPLIFY YOUR FRACTION).
Blank 1:
Blank 2:

Answers

Answer: 1/3

Step-by-step explanation:

Number of red marbles = 5

Number of blue marbles = 9

Number of yellow marbles = 8

Number of and black marbles = 6

Total number of marbles = 28

If Taylor pulled out a yellow one and didn't replce it, there'll be 27 marbles left since one has been removed, then the probability of picking blue marbles will be:

= Number of blue marbles / Total marbles

= 9 / 27

= 1/3

The probability of picking a blue marble is 1/3.

If (x - 2)2 + 5(x - 2) = -6, which of the following could be the value of x - 2?
A
-1
B
-3
C
-4
D
-5

Answers

Answer: A. -1

Step-by-step explanation:

(x - 2)2 + 5(x - 2) = -6

2x-4 + 5x -10= -6

Combine like terms

7x-14=-6

Add 14 to both sides

7x=8

Divide

X= 8/7 or 1.14 (rounded)

1.14 - 2= -0.86 which can be rounded to -1

A number x added to a number y is equal to 100. The number y is also equal to 10 more than the number x doubled. Write and solve a linear system to find the value of x and y.

Answers

Answer:   x + y=100---equation 1

               y =10+ 2x-----equation 2

                 x=30, y=70

Step-by-step explanation:

Given that

x added to a number y is equal to 100 which means that

x + y=100

and also that

y is also equal to 10 more than the number x doubled which is

y =10+ 2x

we have the linear systems to solve the equations as

x + y=100---1

y =10+ 2x-----2

Solving

Putting the value of y =10+ 2x in equation 1

x +10+ 2x =100

10+3x=100

3x=100-10

x=90/3=30

x=30

y=10 +2x = 10+2x30 =70

Find the area of the shaded region. The radius of the large circle is 10 m. Round answer to the nearest hundredth.

Answers

Answer:

hello the figure related to your question is missing attached below is the missing figure

answer : 157.08 m^2

Step-by-step explanation:

Calculate the area of the shaded area

= Area of the large circle - Areas of the small circles

= (( [tex]\frac{\pi }{4}[/tex] ) * D^2) - 2(  ( [tex]\frac{\pi }{4}[/tex] ) * d^2 )     given that the small circles are congruent

= (( [tex]\frac{\pi }{4}[/tex] ) * 20^2 ) - 2 ( ( [tex]\frac{\pi }{4}[/tex] ) * 10^2 )

= 314.16 - 157.08

explain how your know that 88is a solution to the equation 1/8 R = 11 complete the sentences
The word solution means to
88 is a solution to 1/8 R = 11 because

Answers

Answer:

In this equation R would equal 88 because it satisfies the equation.

Step-by-step explanation:

You must solve for R by isolating the variable(which is R). To move the 1/8, multiply both sides by 8. You would do this because 8 is the reciprocal of 1/8. With R on it's own, to keep both sides equal multiply 11*8. That equals 88, which satisfies the equation, which is why 88 is the solution.

The population of village increases by 2% every year. The current population is 1000. What will be the population after 2 years?

Answers

Answer:

1040 approx

Step-by-step explanation:

Given data

Rate = 2%

Population= 1000

Time = 2 years

We can apply the expression below to find the population after 2 years

A= P(1+r)^t

Substitute

A= 1000(1+0.02)^2

A=1000(1.02)^2

A=1000*1.0404

A=1040.4

Hence the population is 1040 approx
