There is 3/4 pound of cream in a containwr. Julian will use 3/8 pound of cream to make crème brûlée. What fraction of a pound of
Ksivusya [100]

Answer:

\frac{3}{8}\ pound of cream will remain in the container.

Step-by-step explanation:

Given:

Amount of cream in the container = \frac{3}{4}\ pound

Amount of cream used to make crème brûlée = \frac{3}{8}\ pound

We need to find the amount of cream remain in the container.

Solution:

Now we can say that;

the amount of cream remain in the container is equal to Amount of cream in the container minus Amount of cream used to make crème brûlée.

framing in equation form we get;

amount of cream remain in the container = \frac{3}{4}-\frac{3}{8}

Now we will make the denominator common using LCM we get;

amount of cream remain in the container = \frac{3\times2}{4\times2}-\frac{3\times1}{8\times1}= \frac{6}{8}-\frac{3}{8}

Now denominators are common so we will solve the numerators.

amount of cream remain in the container = \frac{6-3}{8}=\frac{3}{8}\ pound

Hence \frac{3}{8}\ pound of cream will remain in the container.

The length of Hillcrest Garden is 6 feet more than its width. A 3-foot wide walkway surrounds the outside of the garden. The tot
Ne4ueva [31]

Answer: The dimensions of the garden would be 18 feet and 24 feet.

Step-by-step explanation:

Let the width of garden be 'x'.

Let the length of garden be 'x+6'

Since there is 3 foot wide walkway surrounds the outside the garden.

Area of walkway = 288 square feet

So, According to question, it becomes,

2z(x+y+2z)\\\\288=2\times 3(x+x+6+2\times 3)\\\\288=6(2x+6+6)\\\\288=6(2x+12)\\\\\dfrac{288}{6}=2x+12\\\\48=2x+12\\\\48-12=2x\\\\36=2x\\\\x=\dfrac{36}{2}\\\\x=18

Width = 18+6 =24 feet

Hence, the dimensions of the garden would be 18 feet and 24 feet.

Ten balls are to be randomly chosen from an urn containing 8 red, 10 green and 12 yellow balls. a) What is the probability that
irina1246 [14]

Answer: 0.9985

Step-by-step explanation:

8 red balls

10 green balls

12 yellow balls.

Re: probability = favourable outcome/possible outcome.

To get probability of at least one yellow ball being chosen, we first get the probability that no yellow ball is chosen and subract the answer from 1.

Doing this,

Favourable outcome = number of ways to pick the balls without considering a yellow ball = 18C10

Possible outcome = number of ways to pick 10 balls without restrictions = 30C10

Probability of not choosing a yellow ball = (18C10)/(30C10)

= 43758/3.005 * 10^7

=0.0015.

Hence, probability of choosing at least one yellow ball = 1 - 0.0015 = 0.9985.
