ANSWER

$450 {cm}^{3}$

EXPLANATION

The prism shown is a rectangular prism or cuboid.

The volume of a cuboid is given by:

$Volume=l \times b \times h$

From the diagram, the length is l=15cm ,the breadth is b=10cm and the height is h=3cm.

We substitute the values into the formula to obtain,

$Volume=15 \times 10 \times 3$

We simplify to get,

$Volume=450 {cm}^{3}$

zmey [24]

15.5-3.5=12. this is how many hours he has worked already.

12/1⅓=9. this is because how many hours he has worked per how many hours he worked per day to show how many days he worked

the answer is 9 days.

12hours * 1day/1⅓ hours
^^ignore that if it doesn't make sense, but basically the hours will cancel and you'd be left with days as your only unit to show why you would divide 12 by 1⅓

hope this helped!

A: {71,73,79,83,87} B:{57,59,61,67}

Answer:

$\frac{3}{5}$ .

Step-by-step explanation:

We have been given two sets as A: {71,73,79,83,87} B:{57,59,61,67}. We are asked to find the probability that both numbers are prime, if one number is selected at random from set A, and one number is selected at random from set B.

We can see that in set A, there is only one non-prime number that is 87 as it is divisible by 3.

So there are 4 prime number in set A and total numbers are 5.

$P(\text{Prime number from A})=\frac{4}{5}$

We can see that in set B, there is only one non-prime number that is 57 as it is divisible by 3.

So there are 3 prime number in set B and total numbers are 4.

$P(\text{Prime number from B})=\frac{3}{4}$

Now, we will multiply both probabilities to find the probability that both numbers are prime. We are multiplying probabilities because both events are independent.

$P(\text{Prime number from A and B})=\frac{4}{5}\times \frac{3}{4}$
