multiple 8 on both sides to cancel out the "divide by 8" and you will get x+11=24. then you subtract 11 from both sides to cancel out +11

you will get x=13

A student reduces the temperature of a 300 cm3 balloon from 60°C to 30°C. What will the new volume of the balloon be? (Remember
amid [387]
Assuming constant pressure, V/T = constant.

Where T is absolute temperature, and V is volume.

T1 = 60 ° + 273.15 = 333.15 K
V1 = 300 cm^3

T2 = 30°C + 273.15 = 303.15 K
V2 = ?

V1 / T1 = V2 / T2 = >  V2 = [V1/T1] * T2

V2 = [300cm^3 / 333.15K] * 303.15K = 272.9 cm^3

Answer: 272.99 cm^3

To estimate the height of a building, a stone is dropped from the top of the building into a pool of water at ground level. The
kupik [55]

Answer:

The height of the building is 153.664 meter.

Step-by-step explanation:

Consider the provided function.

s(t) = 4.9t^2 + v_0 t + s_0

Here t represents the time v₀ represents the initial velocity, s₀ represents the initial height and s(t) represents the height after t seconds.

It is given that the splash is seen 5.6 seconds after the stone is dropped.

That means after 5.6 seconds height s(t) = 0, Also the initial velocity of the stone is 0.

Substitute respective values in the above function.

0 = 4.9(5.6)^2 +5.6(0)+ s_0

0 = 4.9(31.36)+ s_0

s_0=-153.664

As height can't be a negative number so the value of s₀ is 153.664.

Hence, the height of the building is 153.664 meter.

the total is expressed as

y=mx+c

total =x+27

Step two:

the number of visits can be found as

29=x+27

29-27=x

x=2
