Answer:
Abelito had the greater average speed
Step-by-step explanation:
Given
Bobby:
Abelito
Required:
Who had a greater average speed
Average speed (S) is calculated as:
We will make use of mph (miles per hour) as the unit of speed.
For Bobby:
Convert minute to hour
For Abelito
Convert minute to hour
By comparison: 12.5mph > 8mph
Hence: Abelito had the greater average speed
Answer:
9:50
Step-by-step explanation:
To get the ratio, we can just simplify a fraction down to 1.
Since there's 18 dimes, and 100 coins in total, we'll start with the fraction
18/100
Put 18/100 in simplest form
9/50
Then Turn the fraction into a ratio
9/50 -> 9:50
For every 9 dimes there's 50 coins.
I hope this helped.
(Simplified to 1, is 1/5.56 or 1:5.56)
Answer:
y = -4/5x - 0.8
Step-by-step explanation:
A(-6, 4)
B(4, -4)
Find slope using the two points above:
m = (y₂ - y₁) / (x₂ - x₁)
= (-4 - 4) / (4 - (-6))
= -8 / 10
m = -4/5
Find y-intercept using m from above and anyone point, let's use (-6, 4):
y = mx + b
4 = -4/5(-6) + b
4 = 24/5 + b
b = -0.8
Use m and b from above to form equation of line:
y = mx + b
y = -4/5x - 0.8
Answer:
A:40%
B:7.8
Step-by-step explanation:
Using a proportion , you can solve for the bottom side.
13/19.5 = 5.2/x
multiply 19.5 and 5.2 and rewrite the equation
101.4=13x
x=7.8
To find the scale, divide 5.2 by 13
5.2/13=0.4
Double check by dividing 7.8 by 19.5
7.8/19.5=0.4
0.4=40%
