Write 5/3 as a mixed number.
Answer:
1 [tex]\frac{2}{3}[/tex]
One and two thirds
Step-by-step explanation:
Divide the numerator by 3
Write down the whole number answer
Use the remainder as the new numerator over the denominator, which is the fraction part of the mixed number.
I hope this helps!!
The fraction 5/3 as a mixed number is [tex]1\frac{2}{3}[/tex].
To write the fraction 5/3 as a mixed number, we need to find the whole number and the proper fraction parts.
A mixed number is a combination of a whole number and a proper fraction (where the numerator is smaller than the denominator).
Divide the numerator (5) by the denominator (3).
5 ÷ 3 = 1 with a remainder of 2
The quotient (1) represents the whole number part, and the remainder (2) becomes the numerator of the proper fraction.
The denominator remains the same, which is 3.
Hence, the mixed number representation of 5/3 is [tex]1\frac{2}{3}[/tex].

At an intersection, the red light of route A is red for 60 seconds and the other two lights are red for 45 and 75 seconds, respectively. What is the probability that a car traveling from route A will encounter a red light at an intersection?
Answer:
1/3
Step-by-step explanation:
The probability of an event E in a sample space S is P(E) = desired outcome/total number of possible outcomes.
The probability of encountering a red light at the intersection P(red light on) = time it takes red light to stay on/total time all the lights stay on, where desired outcome = time it takes red light to stay on on route A and total number of possible outcomes = total time all the lights stay on.
Since all the other two lights have to come on after the red light goes off and before the red light comes on again, and the red light has to be on to encounter it at an intersection.
So, P(red light on) = 60 s/(60 s+ 45 s+ 75 s)
= 60 s/180 s
= 1/3

Solve for x: 10(x + 1) = 2x - 7
Answer:Simplifying
x = -2.125
Step-by-step explanation:Add '-10' to each side of the equation.
10 + -10 + 8x = -7 + -10
Combine like terms: 10 + -10 = 0
0 + 8x = -7 + -10
8x = -7 + -10
Combine like terms: -7 + -10 = -17
8x = -17
Divide each side by '8'.
x = -2.125
Simplifying
x = -2.125
It takes Serina 0.25 hours to drive to school. Her route is 16 km long. What is Serina’s average speed on her drive to school?
Answer:
D/T - 16 KM/ 0.25hours = 64 KM/H
Step-by-step explanation:
Answer:
Step-by-step explanation:
if Serina needs t=0.25 hours to drive to school, which is s=16 km away
her speed is
v= s/t t=0.25h
v=16 km/15 min or v= 64 km/h ( multiply by 4 to get 1 hour)

1. Solve for q:
√3q + 2 = √5
2. solve for d:
4d + 1 = √3
3. Solve for m:
m/√3 - 11 = 4
Answer:
1) q = (sq rt 15 - 2) / 3
2) d = (sq rt 3 - 1) / 4
3) m = 15 * sq rt 3
Step-by-step explanation:
1.√3q + 2 = √5
we bring to the power of 2 each element
(√3q)^2+2^2=√5^2
3q+4=5
3q=4-5
q=1/3
2.
4d+1=√3
we do the same thing
16d^2+1=3
16d^2=2
d^2=2/16
d^2=1/8
d=√1/√8
3.
m/√3 -11=4
first we rationalise by multiplying the first fraction with √3
m√3 /3-11=4
now we can bring to the power of 2

There were 24 boys and 20 girls in a chess club last year. This year
the number of boys increased by 25% but the number of girls
decreased by 10%.
Find the overall percent change in membership of the club.
10
Answer:
35%
Step-by-step explanation:
If you take the amount of percent the girls decreased, and the amount the boys increased in percentages, you will have your answer when just adding them together. So the answer is 35% or as in 6 boys joined and 2 girls left. So that gives you a total of 8 joining or leaving the chess club or 35% difference.

Is it necessary to have a common denominator when you multiply two fractions? Explain.
Answer:
No
Step-by-step explanation:
Multiplying fractions does not require that the fractions have the same denominator. Instead, the numerators are multiplied with each other and the denominators are multiplied with each other. However, the resulting fraction may not be in lowest terms so it may need to be reduced.

The graph for the equation y = 2 x minus 2 is shown below. On a coordinate plane, a line goes through points (0, negative 2) and (1, 0). If another equation is graphed so that the system has one solution, which equation could that be? y = 2 (x + 1) y = 2 (x minus 1) y = 2 (x minus 2) y = negative 2 (x + 1)
THIS IS TIMED
Answer:
i think it is b correct me if i am rong
Step-by-step explanation:
The correct equation for the solution to be one will be y = 2(x -1) hence, the correct option is (B).
What is a graph?The link between lines and points is described by a graph, which is a diagrammatic representation of a network. A graph is made up of some points and the distance between two. It doesn't matter how much time the lines are or where the points are located. A node is a name for each constituent in a graph.
For example to draw the equation y = 2x +9 this will draw a straight line in the coordinate geometry.
Given that an equation y = 2x - 2 now another equation draw which should intersect with the line y = 2x - 2 at a single point only so that the system has only one solution.
so the y = 2x - 2 should be matched with any one option.
By cross-checking the option it will be (B) with equation y = 2(x -1).

V = √ 20 L to estimate the speed of a car, v , in miles per hour, based on the length, L , in feet, of its skid marks when suddenly braking on a dry, asphalt road. At the scene of an accident, a police officer measures a car's skid marks to be 108 feet long. Approximately how fast was the car traveling? Round your answer to the nearest tenth (one decimal place) of a unit.
Answer:
46.5 miles per hour
Step-by-step explanation:
Given that :
Speed of A car v in miles per hour based on length L in feets ;
V = √(20L)
Skid mark (L) = 108 feets
V = √(20 * 108)
V = √2160
V = 46.475800 miles per hour
V = 46.5 mph
