Answer:

Fₐ ≈ 38.97 N

Step-by-step explanation:

The illustration forms a right angle triangle with the horizontal side been the side of horizontal force.

The horizontal component of the applied force can be calculated as follows

Force applied on the block = 45 N

The force on the horizontal is the force of acceleration use to pull the block .

Fₐ = 45 N cos 30°

The formula is gotten by using the cosine ratio of the right angle triangle formed.

Recall

cos 30° = adjacent/hypotenuse

Fₐ = 45 N cos 30°

Fₐ = 45 × cos 30°

Fₐ = 45 × 0.86602540378

Fₐ = 38.9711431703

Fₐ ≈ 38.97 N

Kylie drank 35% ofna 400-mL contanier of water.Eugenia drank 45% of a 350 mL container of water.who drank more?Explain how you k
Andrei [34K]
Let Kylie's container (which is 400ml) be 100%. She drank 35%. Proportion:
400ml - 100%
x ml    - 35%
So Kylie drank:
x=(400*35)/100=140 ml of water

Whole Eugenia's container (350ml) is also 100% and she drank 45%.
350ml - 100%
xml     - 45%
Eugenia drank:
x=(350*45)/100=157,5ml of water

Thus, Eugenia drank (157,5-140)=17,5 ml more than Kylie

A machine stamps 330 parts in 11 minutes. Find the unit rate in parts per hour.
zavuch27 [327]

Answer:

1,800 parts per hour

Step-by-step explanation:

330 parts = 11 min

330/11=30

30 parts = 1 min

60 min = 1 hour

30x60min=1,800

1,800 parts per hour

(ASAP LOTS OF POINTS)
shusha [124]

Answer:

52 inches by 29 inches

Step-by-step explanation:

Let one side by 16x   and the other side be 9x

We know the diameter is 60 inches

Using the Pythagorean theorem

a^2 + b^2 = c^2

(16x) ^2 + ( 9x) ^2 = 60 ^2

256 x^2 + 81x^2 = 3600

Combine like terms

337 x^2 = 3600

Divide each side by 337

337x^2 /337 = 3600/337

x^2 =10.68249258

Take the square root of each side

sqrt(x^2) =sqrt(10.68249258)

x =3.268408264

The sides are 16x by 9x

16*(3.268408264) =52.29453223  or 52

9 *(3.268408264)= 29.41567438 or 29
