Does in anyone know what this is if so please tell me

Answer:

C. 2/7

Step-by-step explanation:

When two pink marbles are taken without replacement then the total number of marbles in the bag are reduced to 21 marbles. So the blue marble, which are currently in total 6 marbles, is taken out of the total of 21 marbles. The calculation of which is done as below:

Probability of Next Marble to be blue

= Blue Marble / Total Marbles in the bag

= 6 / 21

= 2 / 7

Hence, the correct option is C. 2/7

Answer: The circumference is 33.284 cm

Step-by-step explanation:

The equation to find the circumference use the fomula to find it.

3.14 is the simplified version of Pi (I SUGGEST TO USE YOUR CALCULATOR)

C = 2*pi*R /// Circumference = 2 times pi times Radius.

C = 2 * 3.14 * 5.3

C = 6.28 * 5.3

C = 33.284

Given:

A jar of coins has 8 pennies, 5 nickels, 1 dime, and 7 quarters.

To find:

The probability of drawing a quarter, replacing it, and drawing another quarter.

Solution:

A jar of coins has 8 pennies, 5 nickels, 1 dime, and 7 quarters.

Total number of coins = 8+5+1+7 = 21

Probability of getting a quarter is

[tex]P(Quarter)=\dfrac{\text{Number of quarters}}{\text{Total number of coins}}[/tex]

[tex]P(Quarter)=\dfrac{7}{21}[/tex]

[tex]P(Quarter)=\dfrac{1}{3}[/tex]

After drawing a quarter, we replaced it. So, the probability of getting quarter in second draw is the same and first one, .i.e., [tex]P(Quarter)=\dfrac{1}{3}[/tex].

The probability of drawing a quarter, replacing it, and drawing another quarter is

[tex]P=\dfrac{1}{3}\times \dfrac{1}{3}[/tex]

[tex]P=\dfrac{1}{9}[/tex]

Therefore, the required probability is [tex]\dfrac{1}{9}[/tex].

Step-by-step explanation:

9514 1404 393

Answer:

  A, B, D

Step-by-step explanation:

"x increased by 15%" means "x plus 15% of x".

This can be written several ways.

  x + 15%x . . . . . . a direct translation

  x + 15/100x . . . . matches choice B

  x +0.15x . . . . . . with the percentage as a decimal

  (1 +0.15)x . . . . . . matches choice D

  1.15x . . . . . . . . . . matches choice A

_____

Additional comment

It can be helpful to remember that % is a shorthand way to write /100. That is ...

  15% = 15/100

It can also be helpful to remember place value:

  15/100 = "fifteen hundredths" = 0.15

Answer:

x=6 or x=0

Step-by-step explanation:

[tex]5 |x - 3| = 15[/tex]

[tex] |x - 3| = 3[/tex]

[tex]x - 3 = 3[/tex]

or

[tex]x - 3 = - 3[/tex]

Answer:

4. supplementary

5. complementary

Step-by-step explanation:

4 is supplementary because the sum of the two angles is 180°.

5 is complementary because the sum of the two angles is 90°.

Answer:

4. Supplementary

Supplementary angles sum up to 180 degrees.

105 degrees + 75 degrees = 180 degrees

5. Complementary

Complementary angles sum up to 90 degrees.

30 degrees + 60 degrees = 90 degrees

Answer:

13.66 years

Step-by-step explanation:

Given data

P=$510

A=​$1,010.18

R=5%

t= ln(A/P)/r

susbstitute

t= ln(1,010.18/510)/0.05

t=ln1.980/0.05

t= 0.683/0.05

t= 13.66

Hence the time is 13.66 years

Answer:

For 17 the first answer is 1(1/20). The picture can be misleading because the flags are at the same height and the American flag's pole looks shorter. This is only because it is behind the Floridian flag and because the perspective isn't accurate to compare them.

Step-by-step explanation:

The mixed fraction would be 1(5/100) which can be simplified when you divide the fraction by 5 into 1(1/20).

Answer: putting that in slope intercept form : y=-2x+10

Step-by-step explanation:

slope intercept form is y=mx+b.

m= the slope

the slope you gave us is -2

b= the y intercept

a y intercept is the coordinate that touches/crosses the y axis.

to find the y intercept, use the slope (rise over run) you will eventually cross the y axis at 10.

y=-2x+10

i think.

The answer is C. you're welcome.

Answer:

45 degrees

Step-by-step explanation:

if <9 and <10 are corresponding, it means they are equal i.e <9 = <10

Since <9 and <10 are also complementary angles, their sum will be 90 degrees

<9+<10 = 90

<9 + <9 = 90

2m<9 = 90

m<2 = 90/2

m<2 = 45 degrees

Hence the measure of angle 9 is 45 degrees

Answer:

Explanation:

- 5x + 2y = 9

- 5x + 2(7x) = 9

-5x + 2 · 7x = 9

-5x + 14x = 9

9x = 9

9x ÷ 9 = 9 ÷ 9
