A cyclist is travelling at an average speed of 15km/HR. How long will it take to travel a distance of 52 1/2km
Answer:
3.5hour
Step-by-step explanation:
Average speed = Distance/Time
Given
Distance = 52 1/2 km
Speed = 15km/hr
Required
Time
Substitute the given values in the formula
Time = (52 1/2)/15
Time= 105/2 * 1/15
Time = 105/30
Time = 3.5hour
hence it will take 3.5hr to travel a distance of 52 1/2km
What is the first step you would take to solve the equation 5x - 12 = -20?
Divide 5x and -20 by 5.
Add 20 to both sides.
multiply 12 by .
Add 12 to both sides.
Answer:
The first step would be to add twelve to both sides
Step-by-step explanation:
Answer:
add 12 to both sides
Step-by-step explanation:
What we want to do, is to isolate the variable and the numbers on different sides.
if we divide 5x and -20 by 5, what about -12? It's part of the equation too.
If we add 20 to both sides, the numbers and the variable are on the same side, so we'll need to subtract it back off to isolate both.
If we multiply 12 by (what was there) it won't be isolating the variable or numbers. We'll just be increasing the value of the terms already there.
However, if we add 12 to both sides, we'll be isolating both the variable AND the numbers onto different sides.
therefore, add 12 to both sides.
Hope this helps!
A spotlight can be adjusted to effectively light a circular area of up to 7
meters in diameter. What is the maximum number of square meters
that can be effectively lit by the spotlight?
(Draw a circle with a diameter of 7 meters, then solve.)
Answer:
38 square metersStep-by-step explanation:
Use the circle area formula:
A = πr² = πd²/4Substitute the value of the diameter and calculate:
A = 3.14*7²/4A = 38.465 m²Maximum number of square meters is 38
Answer:
Diameter of the spotlight is 7 meters
Radius=Diameter/2=7/2 meters=3.5 meters
Area of the circular spotlight is :---
π×(radius)² =22/7×3.5×3.5=38.5 meter²
The maximum number of square meters that can be effectively lit up by the spotlight is 38.5 square meters.

PLEASE PLEASE HELP, I AM TIMED! What is the equation to the function? Explain.
Step-by-step explanation:
General equation: y = 2 + c/(x - 1)
When x = 4, y = 4.
=> (4) = 2 + c/(4 - 1), c = 6.
Hence the equation is y = 2 + 6/(x - 1).

Aliyah is drawing a ball from one bag and a tile from another bag the first bag contains four green balls and four yellow balls the second bag contains tiles 1 through 5 search
Complete question :
Aliyah is drawing a ball from one bag and a tile from another bag the first bag contains four green balls and four yellow balls the second bag contains tiles 1 through 5 search
What is the probability that she draws a green ball and a tile numbered with 4?
Answer:
1 / 10
Step-by-step explanation:
Given:
Bag content :
Green balls = 4
Yellow balls = 4
Probability = required outcome / Total possible outcomes
P(drawing a green ball) = 4 / 8 = 1/2
Total number of tiles = 5
P(drawing tile numbered 4) = (number of tiles numbered 4 / total number of tiles) = 1 / 5
P(drawing a green ball) * P(drawing tile numbered 4)
= 1 / 2 * 1 /5
= 1 / 10
When Zakir threw a beach ball to his friend, its horizontal velocity changed as it traveled through the air. The relationship between the elapsed time, t, in seconds, since Zakir threw the ball, and its horizontal velocity, V(t), in cm/s is modeled by the following function: V(t) = 4 x(5/8)^t Complete the following sentence about the rate of change of the horizontal velocity of the ball.

Answer:
5/8
Step-by-step explanation:
For khan the full correct answer is Shrinks by 5/8.
Every second, the horizontal velocity of the ball shrinks v by a factor of 5/8.
What is a Function?A function is a law that relates a dependent and an independent variable.
The horizontal velocity in relation with elapse time is given by
[tex]\rm V(t) = 4 x(\dfrac{5}{8})^t[/tex]

The football teams at a recreation center are given money to purchase equipment for the season. Each team receives $50 per player. Let m represent the amount of money a team is given and let p represent the number of players on the team. Express the relationship between m and p as an equation.
A. m=50
B. p=50m
C. m=50p
D. m= p/50
Answer:
Option C: m=50p is the correct answer.
Step-by-step explanation:
Given that:
Amount received per player = $50
Let,
m represent the amount of money each team is given.
p represent the number of players on the team
Amount of money = Amount received per player * Number of players
m = 50p
Hence,
Option C: m=50p is the correct answer.
