Ebony had a sum of money.
She kept ½ for herself. She decided to give the rest away to family and charity.
¾ of the money she gave away went to family.
a) What fraction of the total amount did Ebony give to charity?
a)If the amount was £200, how much money did she give to family?
Answers
Answer: She gave a fraction of 1/4 to charity, and she gave $150 to family
Step-by-step explanation: Ebony had a totaly of $200 dollars to start with to give away that means if she gave 3/4 of $200 to family that would mean she gave $150 dollars to her family
Now the other part of the question is how much of the total amount did Ebony give to charity now if I understand that part correctly then it wants you to give the fraction of the total which would be she gave 1/4 out of the $200 she had for family and charity which means she gave 1/4 of $200 which is $50 to charity

John has a bag of different colored marbles. He has 6 red marbles, 3 blue marbles, 7 yellow marbles, and 5 green marbles. If John reaches into the bag and randomly pulls out a marble, what is the probability that the marble will be blue? (If necessary, round to the nearest tenth.) (as a percent please!!)
Answers
Answer:
P(blue) ≈ 14.3%
Step-by-step explanation:
probability P is calculated as
P = ( favourable outcome ) ÷ ( total number of possible outcomes )
here favourable outcome is blue of which there are 3
number of possible outcomes is the total = 6 + 3 + 7 + 5 = 21
P(blue) = [tex]\frac{3}{21}[/tex] = [tex]\frac{1}{7}[/tex]
to convert to a percentage multiply the fraction by 100%
P (blue) = [tex]\frac{1}{7}[/tex] × 100% = 100% ÷ 7 ≈ 14.3% ( to the nearest tenth )

What is the length of the diagonal of the rectangle?
Answers
Answer:
Length of diagonal of the rectangle is 21.25 units.Step-by-step explanation:
Here we are given Length of the rectangle 17 and Width 12.75. To find length of the diagonal of the rectangle we will substitute the value of length and width in required formula:
We know that,
[tex] \\ \: \: \dashrightarrow \: \: { \underline{ \boxed{ \pink{ \pmb{\mathfrak {Diagonal = \sqrt {(Length)^2 + (Width)^2 }}}}}}} \\ \\ [/tex]
Substituting the required values:
[tex] \\ \: \: \dashrightarrow\sf \: \: Diagonal = {\sqrt{(17)^2 + (12.75)^2}} \\ \\ [/tex]
[tex]\: \: \dashrightarrow\sf \: \: Diagonal = \sqrt{289 + 162.5625} \\ \\ [/tex]
[tex]\: \: \dashrightarrow\sf \: \: Diagonal = \sqrt{451.5625} \\ \\ [/tex]
[tex]\: \: \dashrightarrow \: \: \pink {\underline{ \boxed{ \pmb{\frak {Diagonal = 21.25}}}}} \\ \\ [/tex]

There are 6 green marbles and 4 red marbles in bag A.
There are 8 green marbles and 2 red marbles in bag B.
One marble is going to be taken at random from bag A and placed in bag B.
A marble is then going to be taken at random from bag B.
Work out the probability that this marble will be a green marble.
Answers
Using it's concept, it is found that there is a 0.7818 = 78.18% probability that this marble will be a green marble.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
There are two ways to end up with a green marble selected.
Green in bag A(6/10 probability) and in bag B(9/11 probability).Red in bag A(4/10 probability) and green in bag B(8/11 probability).Hence, the probability that this marble will be a green marble is given by:
[tex]p = \frac{6}{10} \times \frac{9}{11} + \frac{4}{10} \times \frac{8}{11} = \frac{54 + 32}{110} = 0.7818 = 78.18\%[/tex]
