Answer:

can i pls have brainlysit? I really need them. In return I will try to answer this question

Step-by-step explanation:

length(cm) × width(cm) × height(cm) = cubic centimeters(cm³)

use this formula as a first step.

then substitute your values in

length = 3 cm

width = 4 cm

height = 5 cm

so 3 * 4 * 5 = 60 cm^3

B) Make b the subject of the formula a = 4 - 3b​
Ira Lisetskai [31]
A=4-3b
subtract 4 from both sides
a-4=-3b
divide by -3 for both sides
(a-4)/-3 = b

What force would have been applied to the bus from t=16 s to t=21 s? Assume the mass of the bus was 50 kg.
Svetllana [295]

Applying Newton's Second Law, it is found that the force, in Newtons, is given by:

F = 10[v(21) - v(16)]

Newton's Second Law states that Force, in Newtons, is <u>mass times acceleration</u>, that is:

F = ma

In this problem, mass of 50 kg, thus m = 50

Acceleration is <u>change in velocity divided by change in time</u>, that is:

a = \frac{\Delta_v}{\Delta_t}

In this problem, we don't know the velocities, but know that time is from 16s to 21s, thus:

\Delta_t = 21 - 16 = 5

\Delta_v = v(21) - v(16)

Thus, the force is given by:

F = ma

F = m\frac{\Delta_v}{\Delta_t}

F = 50\frac{[v(21) - v(16)]}{5}

F = 10[v(21) - v(16)]

If you buy a bat and ball for $1.10 and the bat is $1 more than the ball most people would answer that the ball costs 10c. Howev
Marina CMI [18]

Answer: the right cost is $1.05 for a bat and 0.5c for a ball.


Step-by-step explanation:

Let's imagine x in the price of bat and y is the price of the ball

From the infor we know that:

x + y= 1.10 (dollars)

and since the bat is $1 more than the ball we can ensure that:

x - 1 = y

Now we can replace y as follow:

x + x - 1 = 1.10

2x - 1 = 1.10

2x = 1.10 + 1

2x = 2.10

x= 2.10/2= 1.05 (dollars)
