Verizon [17]

Answer:

The 22nd Term is -77.

Step-by-step explanation:

The pattern is -5. If you subtract 5 from each starting number you'll get the following number.

Ex: 28 - 23 = 5

23 - 18 = 5

18 - 13 = 5

Subtract 5, 22 times and you will get -77.

A little help pls this old i don't remember any of it

Answer:

Bowling ball

Step-by-step explanation:

A bowling ball has much more mass than all three of the other choices and the amount of kinetic energy is determined based on a object's mass and velocity, but in this case, all 4 balls are traveling at the same velocity. Therefore, we know that the bowling ball has much more mass so therefore it has the most kinetic energy.

A cyclist rides 225 m each minute.About how long does it take to ride 15km? Show all fo your work

Elan Coil [88]

Speed = 225 metres per minute

Distance = 15 km = 15,000 metres

---------------------------------------------------

s=d/t

ts=d

Therefore: t=d/s

--------------------------------------------------

Time = Distance / Speed

Time = (15,000 metres) / (225 metres per minute)

--------------------------------------------------

Let's work it out:

$Time=\frac { 15,000\quad metres }{ \frac { 225\quad metres }{ 1\quad minute\left( s \right) } } \\ \\ =\frac { 15,000\quad metres }{ 1 } \cdot \frac { 1\quad minute\left( s \right) }{ 225\quad metres } \\ \\ =\frac { 15,000 }{ 225 } minutes$

$\\ \\ =\frac { 200 }{ 3 } minutes\\ \\ \frac { 200 }{ 3 } minutes\quad =\quad 66\quad minutes,\quad 40\quad seconds$
