It is 300 hundred points because 5% plus 25% is 30% and that is equal to 300/1000 so the answer is C. 300

Destiny can run one-eighth of a mile in three-quarters of a minute, and she can walk one-quarter of a mile in 4 minutes. How man
yarga [219]

Answer:

a) Destiny can run 1 mile is 6 minutes.

b) Destiny can walk back 1 mile is 16 minutes.

Step-by-step explanation:

The running rate of Destiny is

(\frac{1}{8}) \textrm{mile in} (\frac{3}{4}) \textrm{minutes}

So, she runs 1 mile in 8 \times (\frac{3}{4} )\textrm{minutes}  

= 6 minutes

Hence, Destiny can run 1 mile is 6 minutes.

The walking rate of Destiny is

(\frac{1}{4}) \textrm{mile in} 4  \textrm{minutes}

So, she walks 1 mile in 4 \times (4 )\textrm{minutes}  

= 16 minutes

Hence, Destiny can walk back 1 mile is 16 minutes.

How much force does the atmosphere exert on one side of a vertical wall 4. 00-m high and 10. 0-m long?
serious [3.7K]

A force of 4.05×10⁶ N was exerted on one side of the wall.

<h3>What is the force?</h3>

Force is an external agent capable of changing the state of rest or motion of a particular body. It has a magnitude and a direction.

The following data were obtained from the question:

Breadth (B) = 4 m

Length (L) = 10 m

Standard pressure (P) = 101325 Nm¯²

Next, we shall determine the area of the wall. This can be obtained as follow:

Area (A) = length (L) × breadth (B)

A = 10 × 4

A = 40 m²

Finally, we shall determine the force exerted on one side of the wall as follow:

Standard pressure (P) = 101325 Nm¯²

Area (A) = 40 m²

Pressure (P) = Force (F) /Area (A)

101325 = F/40

F = 101325 × 40

F = 4.05×10⁶ N.

Therefore, a force of 4.05×10⁶ N was exerted on one side of the wall.
