Answer:

30

Step-by-step explanation:

Ur Welcome

The number of problems they were able to solve before the new mathletes joined, 30

Percentage is a way to express a number as a fraction of 100. It is often used to represent ratios and proportions in a more convenient and understandable form, especially in financial and statistical contexts. For example, 50% means 50 per 100, or half of a given quantity. It is denoted using the symbol "%".

Given that,

After a few mathletes join the team, the team is able to solve 40% more problems per session

Let X be the number of problems the team was able to solve before the new mathletes joined.

We know that after the new mathletes joined, they were able to solve 42 problems per session, which is 40% more than before, so:

X x 1.40 = 42

Solving for X:

X = 42 / 1.40 = 30.

Step-by-step explanation:

you are correct all you do is add the four to 41, which is 44. you then divide 2.5 it equals 18

Answer:

18

Step-by-step explanation:

Answer:

Given: In trapezium PQRS, A and B are midpoints of diagonals PR and QS.

To Show: AB=1/2(SR-PQ).

Construction:draw midpoints C and D of SP and RQ respectively and join CA and BD

Proof: In triangle SPQ ,C and B are midpoints of SP and SQ

Therefore,by midpoint theorem

CB || PQ and 2CB= PQ ......1

In triangle QSR B and D are midpoints of QS and RQ

Therefore, by midpoint theorem

BD II SR and 2BD =SR..2

In triangle SPR C and A are midpoints of SP and RP

Therefore by midpoint theorem

CA = 1/2 SR .3

From 2

2 BD = SR =

BD =1/2 SR ........4

From 3 and 4

CA = BD ........,.......5

From 1 and 2

SR -PQ= 2 BD -2 CB -

SR-PQ = 2( BD-CB)

From 5

CA = BD ,

Therefore,

1/2(SR-PQ) =AB

AB= 1/2(SR-PQ)

Hence Showed

Answer:

5^2 < 2^5

Step-by-step explanation:

2^5 = 2x2x2x2x2 = 32

5^2 =  5x5 = 25,

since 25 is less than 32, the comparison 5^2 < 2^5 is correct, or 25 < 32

The value of 2^5 is greater than 5^2.

An expression in maths a sentence with a minimum of two numbers or variables and at least one math operation.

Given that the same digits are used for the expression 2^5 and 5^2

2^5 = 32

5^2 = 25

Therefore, 2^5 > 5^2

Hence, The value of 2^5 is greater than 5^2.

Answer:

Hey mate....

Step-by-step explanation:

This is your answer....

Yes, because a equilateral triangle has 3 equal angles. The 3 angles of a triangle equal 180°. So if the angles are all equal in an equilateral triangle, we do 60 times 3 which equals 180°.

Answer:

y-intercept= (0, 0.4)

x-intercept = (0.3, 0)

Step-by-step explanation:

The intercept is where the line crosses the axis, and a coordinate is written out as, (x,y).

With this knowledge in mind, for the y-intercept, the x coordinate would be 0, and the y coordinate would be 0.4, which is where it crosses the y axis. This would make the y-intercept (0, 0.4).

For the x-intercept, the y coordinate would be 0, and the x coordinate would be where the line crosses the axis, making it 0.3. With these numbers and coordinates in mind, the coordinate for where the line intercept the x axis is (0.3, 0).

Step-by-step explanation:

Answer:

increase by the percent

The fraction will decrease by 20%.

A fraction represents a part of a whole.

Let's assume the original fraction to be x/y.

If we increase the numerator by 20%, it becomes 1.2x.

If we increase the denominator by 50%, it becomes 1.5y.

So, the new fraction will be:

(1.2x) / (1.5y)

Simplifying this expression, we get:

(4x/5y)

The new fraction is (4/5) times the original fraction.

Therefore, the fraction will decrease by 20%.
