A cyclist travels 4miles in 15 minutes. What is her average speed in mph?
Answer:
5
Step-by-step explanation:
Hence, the average speed to the cyclist is 16mph.
What is speed?Speed is defined as the rate of change of position of an object in any direction. Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude.
How to solve?We know,
distance covered = 4 miles
time taken = 15 minutes = [tex]\frac{1}{4}[/tex]hours
speed = [tex]\frac{4}{\frac{1}{4} }[/tex] = 16
Hence, speed is 16.

A boy at an amusement park has 38 ride tickets. Each ride on the roller coaster costs 5 tickets. After riding the roller coaster as many times as he can,how many tickets will the boy have left?
Answer:
He will expend 35 tickets for 7 rides. 3 tickets are left.
Step-by-step explanation:
Giving the following information:
Number of tickets= 38
Tickets per ride= 5
To calculate the number of rides he can make, we need to use the following formula:
Number of rides= number of tickets / tickets per ride
Number of rides= 38/5
Number of rides= 7.6 = 7 rides
He will expend 35 tickets for 7 rides. 3 tickets are left.

Step-by-step explanation:
6 (2n + 5 ) = 66
solve for n
Answer:
n=3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
6(2n+5)=66
(6)(2n)+(6)(5)=66(Distribute)
12n+30=66
Step 2: Subtract 30 from both sides.
12n+30−30=66−30
12n=36
Step 3: Divide both sides by 12.
12n/12 = 36/12
n=3
Answer:
n = 3
Step-by-step explanation:
Distribute 6 into 2n+5, which is 12n +30
Subtract 30 from 66, which is 36
Divide 36 by 12
You're left with n = 3
Or in numbers:
6(2n+5)=66
12n+30=66
12n=36
n=3

1. A triangle has a base of 8km and height of 3km. What is the area of the triangle?
2. What is the area of a triangle with a base of 4 inches and a height of 9 inches?
Help would be much appreciated
Answer:
1. 12 square kilometers
2.18 square inches
Step-by-step explanation:
To find the area of a square you multiply the base and the height. Then you divide it by 2. 8 times 3 divided by 2 is 12. 4 times 9 divided by 2 is 18. Hope this helps!

The volumes of two cylindrical cans of the same shape vary directly as the cubes of their radii. If a can with a six-inch radius holds 1½ pints, how many gallons will a similar can with a 24-inch radius hold?
Answer:
The second similar can with a radius of 24-inch radius will hold 12 gallons
Step-by-step explanation:
The given parameters are;
The volumes of the cylindrical can ∝ (The radius of the cans)³
The volume of first can, V₁ = 1¹/₂ pints
The radius of the first can, r₁ = 6-inch
The radius of the second can, r₂ = 24-inch
Therefore, we have;
V ∝ r³
V = k × r³
∴ 1¹/₂ pints ∝ (6 in.)³
1¹/₂ pints = 43.3125 in³
∴ 43.3125 in³ = k × 216 in.³
The constant of proportionality, k = 43.3125/216 = 0.2005208333
Therefore, we have for the second can, we have;
V₂ = k × r₂³ = 43.3125/216 × (24 in.)³ = 2772 in.³
The volume of the second can = 2772 in.³
1 in.³ = 0.004329 gallons
∴ 2772 in.³ = 2772 × 0.004329 gallons = 12 gallons
Therefore, the volume the second similar can with a 24-inch radius will hold = 12 gallons.
