The area of a trapezium is 35cm2.find its altitude if the bases is 6cm and 8cm

r-ruslan [8.4K]

Answer: altitude: 5 cm

Explanation:

$\sf \dfrac{1}{2} ( a + b) h = Area \ of \ trapezium$

[ <u>a and b are bases, h is the altitude</u> ]

Here given:

Area = 35

a = 6

b = 8

h = ?

Solve for altitude:

$\sf \rightarrow \sf \dfrac{1}{2} ( 6 + 8) h = 35 \ \ \ \Rightarrow \ \ \ \dfrac{1}{2} ( 14) h = 35 \ \ \ \ \Rightarrow \ \ \ \ 7 h = 35 \ \ \ \ \Rightarrow \ \ h = \dfrac{35}{7} \ = \ 5$

How may minutes is 40% of 2 hours

8090 [49]

Well, we know that 1 hour is 60 minutes which means 2 hours is 120.
so to find the answer we turn 40% into a decimal which would be .40

Take .40 and multiply that by 120.
.40 * 120 is 48

40% of 2 hours is 48 minutes.

Hope this helps!

√24 is between which 2 numbers? Question 6 options: 1 and 2 2 and 3 3 and 4 4 and 5

Goryan [66]

The answer is: between 4 and 5

The way I figured this answer was by simply finding the square of the numbers

$1^{2} = 1$
$2^{2} =4$
$3^{2} =9$
$4^{2} =16$
$5^{2} =25$

Since 24 is between 16 and 25 then that has to be your answer.
