There are 8students who have3/4 of a cake they want to share. How much of the cake will each student get if they split it evenly

emmainna [20.7K]

Hey!!

here is your answer >>>>

If there are 8 students, and who have 3/4 the cake to share equally, we will have to divide 3/4 with 8.

which is( 3/4)/(8)

Now, we will have to take a reciprocal, we get,

(3/4)(1/8)

which is 3/32

which is
Each student gets, 3/32 of the cake!

Hope my answer helps!

How do you simplify the radical expression, 24- sqrt(720 over 4

baherus [9]

24- sqrt(720/4) divide 720 by 4

24 - sqrt (180) now break down 180 to 9*4*5

24- sqrt(9) *sqrt(4) *sqrt (5) so 9becomes 3, 4 becomes 2

24- 3*2*sqrt(5) multiply 3 and 2

24-6sqrt(5)

Solve Fast Please!!!!!!!!!!!!!! ok thanks, Bye (2x−5)^2−.5x<(2x−1)(2x+1)−15

Andrews [41]

Keep these rules in mind:

(a + b)² = a² + 2ab + b²
(a - b)² = a² - 2ab + b²
(a + b)(a - b) = a² - b²

Firstly, solve the exponent and multiplication:

$4x^2-20x+25-0.5x$

Next, combine like terms:

$4x^2-20.5x+25$

Next, subtract 4x² on both sides:

$-20.5x+25$

Next, subtract 25 on both sides:

$-20.5x$

Lastly, divide both sides by -20.5. And since you are dividing by a <u>negative</u>, flip the inequality sign:

$x>2$

<u>Your answer is x > 2.</u>

Suppose a family has three children of different ages. We assume that all combinations of boys and girls are equally likely. (a)

Ivan

Answer:

a) There are 8 possible combinations and each probability is 1/8.

b) The probability that it is a boy given that there are two girls is 3/8

Step-by-step explanation:

a) The sample space is given by:

BBB (3 boys)

BBG (Boy, boy, girl)

BGB (Boy, girl, boy)

BGG (Boy, girl, girl)

GBB (girl, boy, boy)

GBG (girl, boy, girl)

GGB (girl, girl, boy)

GGG (3 girls)

The probability of each combination is the same:

P(BBB)=P(B∩B∩B)= $\frac{1}{2} \frac{1}{2} \frac{1}{2}=\frac{1}{8}$

2) There are three possible combinations in which there are 2 girls and 1 boy:

BGG, GBG, GGB

So the probability is given by:

P(BGG ∪ GBG ∪ GGB)= $\frac{1}{2} \frac{1}{2} \frac{1}{2}+\frac{1}{2} \frac{1}{2} \frac{1}{2}+\frac{1}{2} \frac{1}{2} \frac{1}{2}=\frac{3}{8}$
