A man drives 3 km east from home to the store and then 2 km west to a friend’s house. What is his displacement from his starting point at home?
Answer:
1 kilometer east
Step-by-step explanation:
if you subtract 2 from 3 you get one, plus it's east with the bigger number, so that's why it's one kilometer east
The displacement from his starting point at home is 1 km.
What is a vector?The quantity which has magnitude, and direction, and follows the law of vector addition is called a vector.
A man drives 3 km east from home to the store and then 2 km west to a friend’s house.
The term "displacement" refers to a shift in an object's location. It is a vector quantity with a magnitude and direction.
The displacement from his starting point at home is calculated as,
Displacement = 3 - 2
Displacement = 1
The displacement from his starting point at home is 1 km.

Amar cycles at a speed of 18km/h.
It takes him 55 minutes to cycle between two villages.
Calculate the distance between the two villages
Answer:
The distance between the two villages is 16.5 Km
Step-by-step explanation:
Constant Speed Motion
It's a type of motion in which the distance of an object changes by an equal amount in every equal period of time.
If v is the constant speed, the object travels a distance x in a time t, given by the equation:
x=vt
Amar cycles at v=18 Km/h for t=55 minutes. We need to calculate the distance traveled between the two villages.
Since the speed and the time are given in different units, we convert the time to hours, recalling that 1 hour=60 minute.
t=55 min = 55/60 hours
For the sake of precision, we won't operate the division so far. Compute the distance:
x=18 *55/60=16.5 Km
The distance between the two villages is 16.5 Km

If Alyssa makes $10 a week and has $70 right now how long will it take her to have $1750?
Answer:
168 weeks
Step-by-step explanation:
Come up with an equation, I came up with 10x + 70 = 1750
Because she already has 70$ and x = the amount of weeks.
Now all you have to do is solve.
10x + 70 = 1750
- 70 -70
------------------------
10x = 1680
10/10 1680/10 = 168
x = 168
You have $121 in a savings account and save $1 2
per week. Your friend has S9 I in a savings
account and saves SI 7 per week. How many

It will take 6 weeks for you and your friend to have the same balance.
First, you must set up your equation, with [tex]x[/tex] representing the amount of weeks
until you and your friend have the same balance.
[tex]121+12x=91+17x[/tex]
Then, you must subtract 91 on both sides.

4.5 times what equals 5
Answer:
REEEEEEEEEEEEEEEEEEEEE
Step-by-step explanation:
i thnk that the answer is .9333 !!
The 4.5 times 10/9 equals 5. In other words, if you multiply 4.5 by 10/9, you get the value of 5.
To find the number that, when multiplied by 4.5, equals 5, we can set up an equation and solve for the unknown number.
Let's represent the unknown number as 'x':
4.5 * x = 5
To isolate 'x', we need to get rid of the coefficient 4.5. To do that, we'll divide both sides of the equation by 4.5:
x = 5 / 4.5
Now, perform the division:
x = 1.111...
The result is a repeating decimal, which means the number that satisfies the equation is 1.111... (with 1 repeating indefinitely).
To express the result more precisely, we can write it as a fraction:
x = 5 / 4.5 = 10 / 9
Therefore, 4.5 times 10/9 equals 5. In other words, if you multiply 4.5 by 10/9, you get the value of 5.

Joe bought a box of laundry detergent that contains 195 scoops. Each load of laundry uses 2 1/2 scoops. How many loads of laundry can he do with this one box?
Answer:
a) Number of laundry he can do with this box = 78 laundries.
b) Price he paying for each load = 0.256 $
Explanation:
Total scoop contained in detergent box = 195 scoops.
Scoops used by each load of laundry = scoops = 2.5 scoops
Number of laundry he can do with this box = 195/2.5 = 78 laundries.
Price of detergent box = 19.99 $
Price he paying for each load = Total price/ Number of loads
= 19.99/78
= 0.256 $

A rectangle has a length that is 3 more than twice the width. Its perimeter is 96 inches.
Which equation models this?
Answer:
8x=96 inch
Step-by-step explanation:
How its in the draw you have this situation then the equation that model is the next one:
2*(3X) + 2*X = 96 inch
6X + 2X = 96 inch
8X=96 inch
We must multiply due that there is two sides that measure the same.
The equation which models this situation is,
⇒ 96 = 2 ((3 + 2x) + x)
or ⇒ 96 = 2 (3 + 3x)
What is mean by Rectangle?A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.
We have to given that;
A rectangle has a length that is 3 more than twice the width.
And, Its perimeter is 96 inches.
Let the width of rectangle = x
So, The length of rectangle = 3 + 2x
Now, We know that;
⇒ Perimeter of rectangle = 2 (Length + Width)
Substitute all the values, we get;
⇒ Perimeter of rectangle = 2 (Length + Width)
⇒ 96 = 2 ((3 + 2x) + x)

Maya has a smart phone data plan that costs $50 per month that includes 2 GB of dat, but will charge extra $15 per GB over the included amount. How much would Maya have to pay in a month where she used 3 GB over a limit? How much would maya have to pay in a month where she used over by x GB?
Answer:
a. $65
b. $(50 + 15x)
Step-by-step explanation:
A. From the question, we are told that the first 2 GB of data costs $50 while the subsequent extra GB cost $15 per GB
so for 3 GB, the normal $50 is charged for the first 2 GB while an extra $15 is charged for the extra 1 GB
so, the total amount charged for 3 GB will be $50 + $15 = $65
B. Amount to be paid in a month where x GB is used over the normal
Firstly, she will pay the $50 , then for the extra she will be paying $15 * x = $15x
So the amount to be paid will be;
$50 + $15x = $(50 + 15x)

the mean mass of 6 boxes is 45kg. one of the boxes with a mass of 50kg is removed. calculate the new mean mass of the remaining boxes
Answer: 6 boxes. average 45 each.
Step-by-step explanation:
The mean of a dataset if the average of the dataset.
The new mean mass of the remaining boxes is 44 kg
From the question, we have:
[tex]\mathbf{\bar x = 45}[/tex] --- mean of 6 boxes
The mean of a dataset is:
[tex]\mathbf{\bar x = \frac{\sum x}{n}}[/tex]
So, we have:
[tex]\mathbf{45 = \frac{\sum x}{6}}[/tex]
Multiply by 6
[tex]\mathbf{45 \times 6= \sum x}[/tex]
[tex]\mathbf{\sum x = 270}[/tex]
One of the boxes is 50 kg.
So, the mass of the remaining boxes is:
[tex]\mathbf{Mass = 270 - 50}[/tex]
[tex]\mathbf{Mass = 220}[/tex]
The mean of the remaining boxes is:
[tex]\mathbf{\bar x = \frac{\sum x}{n}}[/tex]
[tex]\mathbf{\bar x = \frac{220}{5}}[/tex]
[tex]\mathbf{\bar x = 44}[/tex]
Hence, the new mean mass of the remaining boxes is 44 kg
