Complete Question:

The area of a trapezium is 400 cm2, the distance between the parallel sides is 16 cm. If one of the parallel sides is 20 cm, then the length of the other side is ______

Answer:

Side\ 2 = 30cm

Step-by-step explanation:

Given

A= 400cm^2 --- Area

h = 16cm --- Height  

Side\ 1=20cm

Required

The length of the other side (Side 2)

The area of a trapezium is:

A = \frac{1}{2}(Side\ 1 + Side\ 2) * h

400 = \frac{1}{2}(20 + Side\ 2) * 16

400 = (20 + Side\ 2) * 8

Divide both sides by 8

50 = 20 + Side\ 2

Collect Like Terms

Side\ 2 = 50 - 20

Side\ 2 = 30cm

A craft club makes 95 identical paperweights. They got $230.85 from those paperweights. If the profit the club makes is two time
ahrayia [7]

Answer:

the cost of making each paperweight = $0.81

Step-by-step explanation:

First let us calculate the selling price for each paperweight as follows:

total amount gotten = $230.85

number of paperweights = 95

∴ 95 paperweights = $230.85

∴ 1 paperweight = 230.85 ÷ 95 = $2.43

selling price of 1 paperweight = $2.43

Next, let the cost of making 1 paperweight be 'x'

selling price of paperweight = cost of making + profit gotten

The cost of making the paper weight (x) plus the profit made on the paper weight (2x) equals the selling price of each paper weight.

x + 2x = 2.43 (the profit the club makes is two times as much as the cost to make each paperweight)

∴ 3x = 2.43

x = 2.43 ÷ 3 = 0.81

Therefore, the cost of making each paperweight = $0.81

A committee that consists of five members are to be chosen from 6 boys and 5 girls. Find the number of different committees that
Maksim231197 [3]

Answer:

150 different committees can be formed

Step-by-step explanation:

We have 6 boys and 5 girls and we want to select 5 members

Out of these 5 members, two boys are selected

Since two boys are selected, we are left with three girls

So, out of 6 boys, we select 2 boys and out of 5 girls, we select 3 girls

Mathematically, we know that the number of ways in which we can select r items from a total n follows the combinatorial formula;

nCr = n!/(n-r)!r!

With this, we have;

6C2 * 5C3

= (6!/(6-2)!2!) * (5!/(5-3)!3!) = 150 different committees can be formed
