She ran the last 100 meters in 2:15 -1:25 = 0:50, so her average speed was

... (100 m)/(50 s) = 2.0 m/s

A car traveling 281 miles 4 hours and 40 minutes what was the average speed of the car in miles per hours

den301095 [7]

ok this one is tricky but I think I can handle it.

The correct answer is more than 60mph but less than 61mph.

60.3mph = 281.399598

or 60.2mph =280.932932

Those are my closest answers.

I really hope this helps

What are the next two numbers in this pattern?

disa [49]

The answer is A. 243, -729

The pattern of this is that they multiply each number by -3.

3*-3=-9
-9*-3=26
27*-3=-81

So you have to multiply -81 by -3. Then multiply that by -3 to get the second number

-81*-3=243
243*-3=-729

A kite is stuck in a 36-ft tree. If the angle of elevation from the kite and the ground is 12, find the length of the kite.

yanalaym [24]

Answer:

173.15 ft.

Step-by-step explanation:

Please find the attachment.

Let L be the length of kite.

We have been given that a kite is stuck in 36-ft tree. The angle of elevation from the kite and the ground is 12.

We can see from our attachment that kite and tree form a right triangle. height of tree is opposite of angle of elevation and length of kite is hypotenuse.

Since we know that Sine relates the opposite and hypotenuse of a right triangle, so we will use sine to find the length of kite.

$sin(12)=\frac{36}{L}$

$L=\frac{36}{sin(12)}$

$L=\frac{36}{0.207911690818}$

$L=173.1504364105882792\approx 173.15$

Therefore, the length of kite is 173.15 ft.
