A hot air balloon is released into the air. During its straight ascent, the angle of elevation was 15° and, 3 minutes later, the

Leni [432]

Answer:

The speed of balloon is 0.16 m/s.

Step-by-step explanation:

BC = 300 m

AD = x

AB = y

time, t = 3 min = 3 x 60 = 180 s

By the triangle, ADC,

$tan 15 = \frac{AD}{BC}\\\\0.27 \times 300 = x \\\\x = 80.4 m$

By the triangle, BDC

$tan 20 = \frac{BD}{BC}\\\\0.36 \times 300 = x + y \\\\x + y = 109.2 m$

So, y = 109.2 - 80.4 = 28.8 m

Speed of balloon = 28.8/180 = 0.16 m/s

4(2x + 3) ÷ 5y

ololo11 [35]

Step-by-step explanation:

We do the brackets first, following BODMAS rules

so, 4× 5x ÷ 5y = 1xy.

= 4 × 1xy

= 4xy.

I guess that's the answer.

Example Of:-

Sum:

2x + 7y

term: 

5x + 7 = 5x and 7 are terms.

product:

2a × 3b

factor: 

always remember, a number is a factor of itself.

5x + 7y

factors = 5 + x + 5x + 7 + y + 7y.

Quotient: 

10d ÷ 5j = 2dj

coefficient: 

In the number 3x, 3 is the coefficient of x.

but, in the number x (raise to) 2, the coefficient is 1.

Which value must be added to the expression x^2+12x to make it a perfect square trinomial a:6 b:36 c:72 d:144

Ksivusya [100]

The answer would be 36. Why?

Because in the equation we would need to do (x + 6)(x + 6) to get a perfect square trinomial.

And 6 * 6 is 36.

So the whole equation would be: x^2 + 12 + 36.

Hope this helped! c:

Find the area of a triangle whose vertices have the coordinates (-1,1) (-1,5) (4,1)

Alekssandra [29.7K]

The triangle that forms is a right-angled triangle. To work out the area, you just do the base × height, all divided by 2.

Therefore, you do 5 (the base) × 4 (the height) and you get 20.

Then you divide by 2 to finish the equation and you should find that the total area of the triangle is 10 units² (20 ÷ 2 = 10).

Hope that helps :)
