The area of ΔIDK is 32.69 square units.

Solution:

Given data:

ID = 7 and Hypotenuse, KI = 11.67.

Let us first find KD:

Using Pythagoras theorem,

\text {Base}^{2}+\text {Height}^{2}=\text {Hypotenuse}^{2}

ID^2 + KD^2 = KI^2

7^2 + KD^2 = (11.67)^2

49 + KD^2 = 136.1889

Subtract 49 from both sides.

KD^2=87.1889

Taking square root on both sides, we get

KD = 9.34

Area of the triangle = \frac{1}{2}\times\text{base}\times\text{height}

                                $=\frac{1}{2}\times{7}\times{9.34}

                                = 32.69

The area of ΔIDK is 32.69 square units.

With a headwind a plane traveled 128 km in 2h. The return trip with a tail wind took 24 min less. Find the air speed of the plan
sertanlavr [38]

Based on the information given, it can be noted that the air speed that the plane has will be 71.1 km per hour.

The number of hours used for the return trip will be:

= 2 hours - 24 minutes.

= 1 hour 36 minutes.

= 1.6 hours.

Therefore, the speed of the air plane will be:

= (128 + 128) / (2 + 1.6)

= 256/3.6.

= 71.1 km per hour.

A total of 150 new recruits join an army training course. After one month, 30 have dropped out. what is the percentage decrease
Pachacha [2.7K]
So what will it be a percentage of? it will be the percentage of the original recruits, of the original 150.

for this, we need to divide the number of recruits that left over all recruits, and multiply by 100%:\frac{30}{150} *100%= \frac{1}{5} *100%=20%

so the number of trainees decreased by 20 %
