The right angles triangle has three sides including the hypotenuse which is opposite to the right angle.
If the hypotenuse - H
Then one side is - H - 2
Third side is 7 cm shorter then H-2
Therefore it’s H -2-7 = H -9
According to Pythagoras theorem
Square of hypotenuse = sum of the squares of the other 2 sides
H² = (H-9)² + (H-2)²
H² = H² -18H + 81 + H² -4H + 4
0 =H² -22H +85
This is a quadratic equation
0 = H² - 17H -5H +85
0 = H (H - 17) -5(H-17)
(H-17) (H-5) =0
H -17=0 or H-5=0
H could be 17 cm or 5 cm
If H =5 cm then
Side 1 -H-2 = 3 cm
And side 2 - H-9 = -4 cm
Since lengths cannot be negative values
H isn’t 5 cm
Therefore H =17 cm
1 side is H-2 = 15 cm
2nd side H -9 = 8 cm
Three sides are 17 cm, 15 cm and 8 cm
Answer:
Step-by-step explanation:3 cars per hr.
I am going to assume that the question is asking how many buttons are in each of the 8 groups.
To find out how many buttons are in each of the 8 groups, we simply need to divide the amount of groups by the total amount of buttons.
3250 / 8 = 406.25
That is unlikely the answer, since buttons are hard to divide into quarters.
**************
This is the more likely solution. There are 8 groups of buttons, with 3250 buttons in each group. To find the total amount of buttons, we just need to multiply the number of groups of buttons there are by the amount of buttons there are in each group.
8 * 3250 = 26000
There are 26,000 buttons total.
Hope that helped =)
Let the x be the number
So,
(4(x+0.5)-2)/2=48
So,
x=24 is the number.
