Mathematics

Answer:

height = 7 cm

Step-by-step explanation:

The area (A) of a trapezium is calculated using the formula

A = \frac{1}{2} h(a + b)

where h is the height and a, b the parallel bases

here a = 6, b = 12 and A = 63, hence

\frac{1}{2} × h × (6 + 12) = 63

\frac{1}{2} h × 18 = 63

9h = 63 ( divide both sides by 9 )

h = 7

kkurt [141]
Number of votes won by A = p
Number of votes won by B = 35

Number of votes won by B are 125% of the number of votes won by A. So we can write that 35 is 125% of p. In equation form we can translate it as:

35 = 125% of p 
35 = 1.25 x p 
p = 35/1.25
p = 28

So the number of votes won be A are 28.

Tema [17]

Answer:

For the parallelogram to be a rectangle, at least one angle must be a right angle or a 90° angle, we know that:

    13x + 34° + 10x + 10° = 90°

=> 13x + 10x                   = 90° - 34° - 10°

=> 23x                            = 46°

=> x                                 = 46°/23 = 2°

Answer: 80 pieces of fruit

Explanation:
Let’s find out the amount of trees Mr Champion has.
He has 14 in total. 1 apple tree and 1 plum tree, and the rest are divided evenly among apricot, pear and peach trees. This means:
1 apple tree + 1 plum tree = 2 trees
14 - 2 = 12 trees
12 / 3 (varieties of trees) = 4
In conclusion, he has
1 apple tree, 1 plum tree, 4 apricot, pear and peach trees.

Now let’s go to the section where he picks the fruit.
6 apricots from 4 trees
10 peaches from 4 trees
3 pears from 4 trees
4 apples from 1 tree

This means:
(6 x 4) + (10 x 4) + (3 x 4) + (4 x 1) = total pieces of fruit picked

24 + 40 + 12 + 4 = total pieces of fruit picked

Now, you add up those four numbers, and you have your answer, 80.



Hope this helps!

B.
if it's is a right angle triangle, two of the x-coordinate of the points must be the same however with the points given, we can tell that the x coordinates are different , the two points are not vertical hence it does not form a right angle triangle.
