Answer:
1.150 seconds or 2.5 minutes
2. 0.2km
Step-by-step explanation:
1. 1.5 x 1000=1500
1500/10=150
150/60=2.5minutes
2. 60mins = 36km -Divide both sides by 60 to get how far he would go in 1 minute/60 secs
1min/60secs=0.6km -Divide both sides by 3 to get how far he would go in 20 secs
20secs=0.2km

3. The diameter of a cylindrical column is 60cm and
its height is 4.2m
The cost of making it is £67.50 per cubic metre.
What is the cost of making it?
Answer:
£80.33
Step-by-step explanation:
The formula for the Volume of a cylinder = πr²h
The diameter of a cylindrical column is 60cm and its height is 4.2m
Converting the diameter to meter
100 cm = 1 m
60 cm = x
Cross Multiply
100 × x = 60 × 1
x = 60/100
x = 0.6m
The diameter of the cylinder = 0.6m
Radius = Diameter/2
Radius = 0.6m/2
Radius = 0.3m
Volume of a cylinder = πr²h
= π × 0.3² × 4.2
= 1.18752 m²
Approximately = 1.19 m²
The cost of making it is £67.50 per cubic metre. What is the cost of making it?
The volume of the cylindrical column = 1.19 m²
Hence:
1m² = £67.50
1.19m² = x
Cross Multiply
x × 1m² = 1.19 m² × £67.50
x = 1.19 m² × £67.50/1 m²
x = £ 80.325
Approximately = £80.33
Therefore, the cost of making the cylindrical column = £80.33

Isaac makes china mugs with names painted on them. He charges a fixed fee for the mug, together with a fixed charge for each letter in the name. Penelope buys a mug for each of her children, Alexander and Lucia. She pays $12.60 for Alexander’s mug and $9.40 for Lucia’s mug. How much would Penelope have to pay for a mug with her own name on it?
Answer:
Not completely sure, and I know its late but for the other people that look at this, 11.80$
Step-by-step explanation:
I found how many more letters Alexander had over Lucia, then when I got 4 divided it in-between 12.60 - 9.40 (3.20) I got 0.8. knowing the letter cost i got the initial fee for the mug (5.40) and added 8x0.8 to it, resulting in my answer 11.80$
Penelope has to pay $11.8 for a mug with her own name on it.
Number of letters in Alexander's name = 9
Number of letters in Lucia's name =5
The Difference in the number of letters in both the names
= 9-5
=4 letters
Alexander pays = $12.60
Lucia pays = $9.40
Difference in payments = 12.60-9.40 = $3.20
It means charge for 4 letters = $3.20
So, charge for 1 letter = $0.80
Number of letters in Penelope's name = 8
So, Penelope will pay = 8*0.80 +fixed fee for the mug
= $6.4 +fixed fee for the mug
What will be the fixed fee for the mug?The Fixed fee for the mug will be the payment done by Penelope for either Alexander or Lucia minus the charge for each word in the word Alexander or Lucia respectively.
The Fixed fee for the mug = $9.40 - charge for each word in the word "Lucia"
The Fixed fee for the mug = 9.40 - 5*0.80 = $5.40
So, Penelope will pay = 6.4 +5.4 =$11.8
Therefore, Penelope has to pay $11.8 for a mug with her own name on it.

In the diagram, how would you determine the length of the hypotenuse using the Pythagorean Theorem?
А
Find the area of the triangle then apply Pythagorean Theorem
B
Subtract the area of the squares and then apply Pythagorean Theorem
С
Add the areas of both squares together and then apply Pythagorean Theorem
D
Find the lenath of one side of each square and then apply the Pythagorean Theorem
Answer:
The hypotenuse formula is simply taking the Pythagorean theorem and solving for the hypotenuse, c.
Step-by-step explanation:
Solving for the hypotenuse, we simply take the square root of both sides of the equation a² + b² = c² and solve for c . When doing so, we get c = √(a² + b²)
The length of the hypotenuse is 17 cm and this can be determined by evaluating the length of one side of each square and then applying the Pythagorean Theorem.
Given :
Area of the small square is 64 [tex]\rm cm^2[/tex].Area of the larger square is 225 [tex]\rm cm^2[/tex].The side length of the smaller square can be calculated as:
[tex]a^2 = 64[/tex]
a = 8
The side length of the larger square can be calculated as:
[tex]b^2 = 225[/tex]
b = 15
So, the length of the perpendicular is 8 and the length of the base is 15. Now, apply the Pythagorean theorem in order to determine the length of the hypotenuse.
[tex]\rm H^2=P^2+B^2[/tex]
Now, substitute the values of known terms in the above expression.
[tex]\rm H^2=(8)^2+(15)^2[/tex]
[tex]\rm H = \sqrt{64+225}[/tex]
H = 17 cm
Therefore, the correct option is D) Find the length of one side of each square and then apply the Pythagorean Theorem.

Elliott buys a TV. The receipt says that the total of the TV is $252.99, including sales tax. The original price (without tax) of the TV was $234.25. What was the percentage for the sales tax?
Answer:
8%
Step-by-step explanation:
234.25$ : 100 = 252.99$ : x

Please Help!!! A bicycle has wheels 28 inches in diameter. tachometer determines that the wheels are rotating at 180 RPM (revolutions per minute). Find the speed the bicycle is traveling down the road.
Answer:
402.336 meters per minutes
Step-by-step explanation:
revolutions per minute = speed in meters per minute / circumference in meters.
Diameter = 28 inches
Circumference of the wheel = 2πr
r = Diameter/2 = 28/2 = 14
Circumference = 2 × π × 14
= 87.964594301 inches
Approximately = 88 inches
Note that:
1 inch = 0.0254 metre
88 inches = x
x = 88 × 0.0254 meters
x = 2.2352 meters
Hence:
Revolutions per minute = Speed in meters per minute / circumference in meters.
Speed = Revolutions per minute × circumference in meters.
Speed = 180 RPM × 2.2352 meters
Speed = 402.336 meters per minutes
Speed of the bicycle traveling down the road = 84π.
It is given that
Diameter of the wheel (2r) = 28 inches, where 'r' is the radius
Speed N(in revolutions per minute) = 180rpm
What is the formula for angular speed?Angular speed ω = [tex]\frac{2\pi N}{60}[/tex]radian per second.
[tex]w= \frac{2*\pi*180 }{60 } = 6\pi[/tex] radian per second
Speed of bicycle V = r*ω
Where,
r= radius of the wheel
[tex]V = 14*6*\pi = 84\pi inches/second[/tex]
Therefore,
speed of the bicycle traveling down the road = 84π.
