Answer: Velocity needs both magnitude and direction

Step-by-step explanation:

Velocity is defined as a Vector quantity which implies that one needs to know both the magnitude and the direction of the object, as a reference frame. The expression for velocity is defined as:

Velocity = Distance * Time <=> V= dt

Acceleration occurs when an object initially moving with a constant velocity, changes motion and velocity increases with time. The expression for acceleration is defined as:

Acceleration = Velocity * Time <=> A= Vt

A typical example of acceleration is a Free Falling Object (i.e. letting a ball drop from a building)

egoroff_w [7]
Target: ratio of pizza places / person < 0.01

<span>The population of 15 blocks of the north side of town is 221 people per block, but there are already 32 pizza places in the area.

population = 15*221 =  3,315

ratio: 32 pizza places / 3315 people = 0.0097 pizza places per person

Which indeed is less than 0.01 => this area is good for their purpose.

The population of 22 blocks of the south area is 150 people per block, and there are 28 pizza places in the area.</span>

population: 22*150 = 3300

ratio: 28 pizza places / 3300 people = 0.00085 which is also less than 0.01

Both places meet the target of less than 0.01 places per person, but the south area seems better than north area.

PLEASE HELP WILL MARK BRAINLY
Alenkinab [10]

Answer:

1: $53750

2: $15975

3: 40

4: 90

5: 51

6a: 20%

6b:204

Step-by-step explanation:

1: to calculate this mulitply 50000*1.075= 53750

2: same deal 15000*1.065=15975

3: We have a ratio of 3:2 and then 60:x because we multiplied the first ratio by 20 to get the 60 in the second we multiply the 2 by 20 as well and get x=40

4: This one is kind of tricky. we know that there are 4 dogs for every 3 cats. We also know that there are 210 animals. This means that 4x+3x=210 solve this and get x=30 you then multiply the ratio 4:3 by 30 and get 120:90

5: 1/5*255=51

5a: 1/5=.2=20%

5b: 255-51=204
