A piece of work takes 20 labourers to complete in 10 days. how many labourers will complete the same job in 25 days if they work

at the same rate?​
Mathematics

Step-by-step explanation:

If 20 labourers=10 days

x labourers = 25 days

10x= 25×20

\frac{10x}{10} =  \frac{25 \times 20}{10}

Cancelling out by 10 on both sides

x = \frac{25 \times 2}{1} \\ x = 50

Therefore, it takes 50 labourers to complete the work at the same rate in 25 days.

First, you should graph the points. For the first number, called the X-Axis, you should to the right or left, and for the second number, called the Y-Axis, you should go up or down.

To find the distance between Point A and Point C, you should simply just count the number of intersections between them (4).

Angle B is a right angle because if the triangle is bisected at B, it will leave a right angle on either side. Therefore, to label it, you should simply just draw a line through Point B all of the way to line (A,C).

The type of triangle you have drawn is an isosceles, because it has 2 equal angles and 2 equal sides.

We know both of the sides that are unknown will be the same because the triangle is bilateral. Then, we can use the bisection we made earlier to solve for the unknown sides using Pythagorean Theorem. Since earlier, we know the entire bottom is 4, we know half of the bottom is 2. We can also see that the height of the triangle is 2. We then plug those numbers into the Pythagorean Theorem (A^2*B^2=C^2) which makes the value of C^2=16. We then take the square root of C^2 and 16 to see that both unknown sides are 4.

How many outcome sequences are possible when a die is rolled 4 times where we say for instance that the outcome is 3 4 3 1 if th
STatiana [176]

Answer:

the possible outcome sequences when a die is rolled 4 times is 1296

Step-by-step explanation:

 Given the data in the question;

a die is rolled 4 times

and outcomes are { 3, 4, 3, 1 }

we know that; possible number of outcomes on a die is n = 6{ 1,2,3,4,5,6 }

Now when we roll a die lets say, r times

then the total number of possible outcomes will be;

N = n^r

given that; r = 4

Hence if we roll a die 4 times;

Total number of possible outcome N = 6⁴

N = 1296

Therefore, the possible outcome sequences when a die is rolled 4 times is 1296
