Katie runs from her house, east 5 blocks, south 3 blocks, west 5 blocks, and north 4 blocks before walking back home. Regarding her jog only: Her total time it takes her 35 minutes. What is her velocity in mi/h and m/s?
Answer:
Step-by-step explanation:
Given question is incomplete; here is the complete question,
Katie runs from her house, east 5 blocks, south 3 blocks, west 5 blocks, and north 4 blocks before walking back home. Regarding her jog only: Her total time it takes her 35 minutes. If city block is about 0.5 miles (0.8 km), what is her velocity in mi/h and m/s?
Katie runs from her house, East 5 blocks, South 3 blocks, West 5 blocks and North 4 blocks.
Since, velocity = [tex]\frac{\text{Displacement}}{\text{Time}}[/tex]
Displacement of Katie from initial position = (3 + 3) blocks
= 6 blocks
Since, each block measure 0.5 miles,
Displacement = 6 × 0.5
= 3 miles
Time taken to cover the distance = 35 minutes ≈ 0.583 hours
Therefore, velocity of Katie = [tex]\frac{3}{0.583}[/tex]
= 5.15 miles per hour towards South
Displacement (in m) = 6 × 0.8
= 4.8 km
≈ 4800 m
Velocity (in m per hour) = [tex]\frac{4800}{0.583}[/tex]
= 8233.27 m per hour towards South

Answer:
y = 2,500x + 5,000
Rate of change = $2500 a year
Initial value = $5000
Step-by-step explanation:
We have 3 values to figure what is the function here, the rate of change, and the initial value.
To find the initial value, find where y is located where x is 0. In this case it's $5000, so that's the initial value.
Now the rate of change. Find y where x is 1. That is $7,500. Subtract $5000 from to get the rate of change, since it's the same. It's constant because of a straight diagonal line.
$7,500 - $5,000 = +$2,500/year
Now the equation. This is not proportional, because y's starting point is not 0. It's greater than that, so an addition sign is in the equation. Do you remember our initial value? That's right! It was $5,000, so put that after the addition sign.
y = ????x + 5,000
You also need to remember the rate of change, which was 2,500. Put that on the left of the addition sign and there's your equation!
y = 2,500x + 5,000
Answer:
y=2500x + 5000
2500

How do I rewrite this expression into radical form??
What is the area of the figure?
Answer:
80 square feet
Step-by-step explanation:
You can split it into a rectangle and a triangle. The area of the rectangle would be 2 * 16 = 32 square feet.
Next, you need to find the height of the triangle. To do this, you can split the triangle into two right triangles and use the pythagorean theorem to find the height. The dimensions of one of the right triangle is 8 for one of the legs and 10 for the hypotenuse. Using the pythagorean theorem, 8^2 + b^2 = 10^2, which is 64 + b^2 = 100, so b^2 = 36 and b = 6. This means that the height is 6. Now, you find the area of the triangle and you get 16 * 6 / 2 = 48.
Adding the area of the rectangle and the triangle: 32 + 48 = 80

The expression in simplified form:
[tex]\frac{4x^5}{8x}=\frac{x^4}{2}[/tex]
Step-by-step explanation:
Given the expression
[tex]\frac{4x^5}{8x}[/tex]
We need to simplify the expression.
Simplifying the expression
[tex]\frac{4x^5}{8x}[/tex]
Cancel the common factor: 4
[tex]=\frac{x^5}{2x}[/tex]
Cancel the common factor
[tex]=\frac{x^4}{2}[/tex]
Therefore, the expression in simplified form:
[tex]\frac{4x^5}{8x}=\frac{x^4}{2}[/tex]
Consider two people where one person is 25% taller than the other but proportion in exactly the same way That the taller person looks like a lager version of the shorter person Suppose the shorter person has a 36%-inch waist what size is the the taller person's waist?
Answer:
46.8 inches
Step-by-step explanation:
Taller person = 30% more than height of shorter individual
Waist size of shorter person = 36 inches
Since they are proportioned in the same way:
Waist size of the taller person will be 30% larger than the waist size of the shorter person :
30% increase in size 36
(100 + 30)% of 36
130% of 36
(130 / 100) * 36
1.3 * 36
= 46.8 inches
What is 160.5cm to feet
Answer:
5.265748
Step-by-step explanation:
i did a cm to feet calcu-lator
have good day
The correct answer is 4 feet 17 inches is 160.5 c.m.
How to convert c.m. to feet?The process to convert cm to feet is simple. 1 cm. is equal to 0.025 feet. So you must multiple the unit by 0.025.
Given:
1 feet = 38.48 cm.
1 cm. = 0.025 feet.
160.5 cm = (0.025/1) * 160.5
160.5 cm = 4.1709 feet
4.1709 feet
4.1709 feet = 4 feet + 1709 inches.
We can 4.1709 feet which is equal to 4 feet 17 inches.
Therefore, 160.5 cm is equal to 4 feet 17 inches.

Albert, bill, claire, and David are all siblings. Bill was born 2 years after Albert. Claire's favourite colour is orange and she is currently half the age of Albert. David enjoys golf and swimming and he is 3 times older than Bill.
The total of their age is 113 using algebraic methods find out their exact age
what is their exact age
Answer:
Albert = 22
Bill = 22 - 2 = 20
Claire = 22/2 = 11
David = 3(20) = 60
Step-by-step explanation:
Let Albert's age = x
Bill = x - 2
Claire = x/2
David = 3(x - 2)
Total sum of their ages = 113
x + x - 2 + 0.5x + 3(x - 2) = 113
x + x - 2 + 0.5x + 3x - 6 = 113
x + x + 3x + 0.5x -2 - 6 = 113
5.5x - 8 = 113
5.5x = 113 + 8
5.5x = 121
x = 121 / 5.5
x = 22
Albert = 22
Bill = 22 - 2 = 20
Claire = 22/2 = 11
David = 3(20) = 60

Answer:
width = 40 feet, length = 90 feet
Step-by-step explanation:
length = 2w + 10
width = w
Perimeter = 260
Perimeter of rectangle = 2length + 2width
Sub the values into that equation:
260 = 2(2w + 10) + 2(w)
260 = 4w + 20 + 2w
260 = 6w + 20
260 - 20 = 6w
240 = 6w
w = 240/6
w = 40
So now we know the width of the garden is 40 feet.
To find the length, substitute the width into the length equation:
length = 2w + 10
length = 2(40) + 10
length = 90 feet
length = 90 feet, width = 40 feet
Hey I need to survey 7 more people who play video games so please answer or comment your answers down below :)

Do you think video games will converge to a single platform in the future?
Playing video games helps me if I have a rough time, I started around 2019. I play adventure type video games, not sure if raft counts, but that is a game I play too often with my friends. I think that video games probably could be played in cars as well but I dont know what else it can be or will be played on. Definitely will not be a single platform, people are too greedy everyone wants a better state then others. (not sure if that makes sense)

Step-by-step explanation:
Please help me with this question!!
Step-by-step explanation:
according to pythagoras theorem
Hypotenuse2 = Perpendicular2 + Base2
c2 = a2 + b2
therefore,
x2 = (4)2 + (4)2
x2 = 16 + 16
x2 = 32
x = √32
hence, x = 4√2
make x the subject. 4x-5=t(x+m)
Answer:
x= tm+5/4-t
Step-by-step explanation:
4x-5=t(x+5)
4x-5-=tx+tm distributive
4x-5-tx=tm substract tx from both sides
4x-tx=tm+5 add 5 to both sides
x * 4+ x(-t) =tm+5 factor x out 4x-tx
x(4-t)=tm+5 factor x out x*4 + x(-t)
x(4-t)/4-t= tm/4-t+ 5/4-t divide each term in 4-t
x= tm/4-t + 5/4-t combine the numerators over the common denominator
x=tm+5/4-t
