How to I find 2/5 of 40 minutes ?

Answers

$(2)/(5)*40 =2*8=16 minutes$
Have a nice day!!! ^^

Well, whenever OF is used in a mathematics, it mostly refers to multiplication. So basically, this means 2/5 x 40. So;
2/5 x 40
80/5.
when 5 divides 80, you get 16. So the answer to this is 16. Hope i helped. Have a nice day.

Find the value of the expression 3m2 2p2 − 15 when m = 3 and p = 10.

Answers

I think you want to say the expression 3m2+2p2-15. The only thing you need to do is to replace the letter with the number. So the expression is 3*3^2+2*10^2-15=212.

There are 399 items advertised in a catalog. If the catalog is 75 pages long, what is the average number of items per page?

Answers

The required average number of items per page is 5.32.

What is the unit rate?

A rate with a second term of one is referred to as a unit rate. To put it another way, a unit rate compares two quantities, with the second number being expressed as 1. Unit rates, such as price per item, speed per hour, or cost per pound, are frequently used to describe a rate per unit of measurement.

Here,
To find the average number of items per page, we need to divide the total number of items by the number of pages:

The average number of items per page = Total number of items / Number of pages

Substitute the given values, and we get:

The average number of items per page = 399 / 75

Simplifying the expression, we get:

The average number of items per page = 5.32 (rounded to two decimal places)

Therefore, the average number of items per page is 5.32.

Answer:

AAS

Step-by-step explanation:

Here is the setting out proof with a - side note:

In Triangle JLM and Triangle JLK

Angle K is equal to Angle M (given) - This is a pair of matching angles

JK = JM (given) - This is a pair of matching sides

Since JL bisects KLM, Angle KLJ = Angle MLJ (Bisect means it cuts it in half, meaning the angle has been divided into two equal parts) - This is a pair of matching angles.

Therefore, Triangle JLM and Triangle JLK are congruent (AAS) - The reason why we do AAS is because we have two pairs of matching angles and a pair of sides are equal. It is call AAS and not ASA, unknown reason but that is just how it is.

Answer:

AAS

Step-by-step explanation:

< K = < L (given)

<KLJ = < MLJ ( because JL bisects < KLM)

JK = JM (given)

we have 2 equal angles and one equal side with the 2 angles adjacent.

Answer is AAS
