Mathematics
1 answer:
Tanya [424]2 years ago
6 0

Answer:

3

Step-by-step explanation:

  1. 3 - 6 = -3
  2. Plug -3 in: -\frac{12}{-3} + (-1)^{3}  
  3. Simplify the fraction. Two negatives equal a positive. It should now look like this: \frac{12}{3} + (-1)^{3}  
  4. Simplify even more. Divide 12 by 3, and change -1 to a positive by removing the plug sign: 4 - 1^{3}  
  5. 1^{3} = 1  
  6. Plug 1 in: 4 - 1
  7. 4 - 1 = 3

I hope this helps!

You are in a hot air balloon looking down at two ponds. Pond A which is in front of your balloon, is at an angle of depression t
MatroZZZ [7]

a. See attachment for the labelled diagram

b. Using the sine ratio, distance from the hot air to pond A is 5,038.9 m, while distance from the hot air to pond B is 6,287.1 m.

c. Distance between the two ponds is 1,263.5 m.

<h3>What is the Sine and Tangent Ratios?</h3>

Sine ratio, is: sin ∅ = opposite side/hypotenuse length

Tangent ratio is: tan ∅ = opposite side/adjacent length.

a. The diagram with the appropriate labels is shown in the image attached below.

b. Use the sine ratio to find the distance from the hot air to pond A (CA) and to pond B (CB):

CA = hypotenuse

∅ = 10°

Opposite = 875 m

sin 10 = 875/CA

CA = 875/sin 10

CA ≈ 5,038.9 m (distance from the hot air to pond A)

CB = hypotenuse

∅ = 8°

Opposite = 875 m

sin 8 = 875/CB

CB = 875/sin 8

CB ≈ 6,287.1 m (distance from the hot air to pond B)

c. Distance between the two ponds, BA = BD + DA.

Apply the tangent ratio to find BD and DA

tan 8 = 875/BD

BD = 875/tan 8

BD = 6,225.9 m

tan 10 = 875/DA

DA = 875/tan 10

DA = 4,962.4 m

Distance between the two ponds = 6,225.9 - 4,962.4 = 1,263.5 m.

Find the solution for the following: Three backpackers cooked rice for dinner. The first one gave 400g of rice and the second 20
victus00 [196]

Answer:

First backpacker should receive $4 and the second one $2

Step-by-step explanation:

notice that the total amount of rice for the three is 600 g.

Then, the first one that gave 400 g contributed 400 out of 600, that is 400/600 = 2/3

The second one contributed 200 out of 600, that is 200/600 = 1/3

then the first one should receive 2/3 of the $6 = (2/3) x 6 = $4

and the second one should receive 1/3 of the %6 = (1/3) x 6 = $2

20 – 10 + 5x = 40 What value of x makes the equation true? *<br> explanition plz
Arlecino [84]

Answer:

6

Step-by-step explanation:

If you solve for x you get your answer. First, 20 - 10 gets you 10. Then you subtract that 10 from both sides of your equation so it now looks like 5x = 30. Last you divide both sides by 5 and get x = 6.
