Dan has ridden 33 miles of a bike course. The course is 60 miles long. What percentage of the course has Dan ridden so far?
Answer:
55%
Step-by-step explanation:
When we are using percentages, what we are really saying is that the percentage is a fraction of 100. "Percent" means per hundred, and so 50% is the same as saying 50/100 or 5/10 in fraction form.
So, since our denominator in 33/60 is 60, we could adjust the fraction to make the denominator 100. To do that, we divide 100 by the denominator:
100 ÷ 60 = 1.6666666666667
Once we have that, we can multiple both the numerator and denominator by this multiple:
33 x 1.6666666666667
60 x 1.6666666666667
=
55
100
Now we can see that our fraction is 55/100, which means that 33/60 as a percentage is 55%.
We can also work this out in a simpler way by first converting the fraction 33/60 to a decimal. To do that, we simply divide the numerator by the denominator:
33/60 = 0.55
Once we have the answer to that division, we can multiply the answer by 100 to make it a percentage:
0.55 x 100 = 55%

The dot plots below show the scores for a group of students who took two rounds of a quiz:
Two dot plots are shown one below the other. The title for the dot plot on the top is Round 1 and the title for the bottom plot is Round 2. Below the line for each dot plot is written Score. There are markings from 5 to 9 on the line at intervals of one. There are 2 dots above the mark 5, 3 dots above the mark 6, 4 dots above the mark 7, and 1 dot above the mark 8. For the bottom dot plot there are 6 dots above the mark 6, 2 dots above the mark 8, and 2 dots above the mark 9.
Which of the following inferences can be made using the dot plot?
The range of each round is the same.
There is no overlap between the data.
Round 1 scores were higher than round 2 scores.
Round 2 scores were lower than round 1 scores.
Answer:
The inference that can be made using the dot plot is:
The range of round 1 is greater than the round 2 range
Step-by-step explanation:
Round 1:
Score Frequency
1 0
2 2
3 3
4 2
5 1
Hence, the minimum score of Round 1 is: 2
maximum score is: 5
Hence, Range=Maximum value-Minimum score
=5-2
=3
Similarly, Round-2
Score Frequency
1 0
2 0
3 0
4 4
5 4
Hence, the minimum score of Round 1 is: 4
maximum score is: 5
Hence, Range=Maximum value-Minimum score
=5-4
=1
The scores of round 2 are higher than round-1.
Since round 2 have a higher frequency for higher scores as compared to round-1.
Hence, Range of round 1 is greater than the range of Round-2.

The number of marbles of different colors stored in a hat is listed below:
1 red marble
8 green marbles
9 blue marbles
Without looking in the hat, Ray takes out a marble at random. He replaces the marble and then takes out another marble from the hat. What is the probability that Ray takes out a blue marble in both draws?
fraction 1 over 9
fraction 1 over 8
fraction 1 over 4
fraction 1 over 2
Answer:
1/4
Step-by-step explanation:
1 red marble, 8 green marbles. 9 blue marbles
There are 1+8+9 = 18 marbles
First marble blue
P(blue) = blue / total = 9/18 = 1/2
He replaces the marble so there are still 18 marbles
1 red marble, 8 green marbles. 9 blue marbles
There are 1+8+9 = 18 marbles
Second marble blue
P(blue) = blue / total = 9/18 = 1/2
Multiply the probabilities together
P(blue, replace, blue) = 1/2 * 1/2 = 1/4

You invest $950 and over 4 years you earn $266. What is the interest rate?
Answer:
7% per year
Step-by-step explanation:
r = rate
t = time (in years)
a = principal + interest (total amount)
p = principal amount
formula r = (1/t)(A/P - 1)
r = (1/4)((1216/950) - 1) = 0.07
r = 0.07
Converting r decimal to R a percentage
R = 0.07 * 100 = 7%/year
Answer:
0.07 = 7%

Bethany is building storage boxes. Each box will have a length of 6 feet, a width of 312 feet, and a height of 512 feet. A quart of paint covers 100 square feet.
How many quarts of paint does Bethany need to buy in order to paint 5 boxes?
4 quarts
6 quarts
7 quarts
8 quarts
Answer:
8 quarts
Step-by-step explanation:
first, we need to find the surface area by doing 2×(6×3.5 + 6×5.5 + 3.5×5.5) = 146.5 feet(2 now we see that we have 5 total boxes so we multiply 146.5x5=732.5 1q=100 square feet so 700=7q but we still have that 32.5 left for we need 8q because it's better to have more than coming up short
Hope this helps:)

What is Geometry?It deals with the size of geometry, region, and density of the different forms both 2D and 3D.
Bethany is building storage boxes. Each box will have a length of 6 feet, a width of 3.12 feet, and a height of 5.12 feet. A quart of paint covers 100 square feet.
The surface area of the box will be
[tex]\rm Surface \ area = 2(lb + bh + hl)\\\\Surface \ area = 2(6*3.12 + 3.12*5.12 + 5.12 *6)\\\\Surface \ area = 2(18.72 +15.9744 + 30.72)\\\\Surface \ area = 2*65.4144\\\\Surface \ area = 130.8288[/tex]
There are 5 boxes, then the surface area of 5 boxes will be
Surface area = 130.8288 × 5 = 654.144
A quart of paint covers 100 square feet.

Answer:
x+4=6.5
x=2.5
Step-by-step explanation:
It says x increased by 4 which means x+4. It also says x is equal to 6.5 so we write x+4=6.5
Now we solve for x.
x+4=6.5
we can get x by itself by removing the 4
x+4-4=6.5-4
we have to do the same thing to each side to keep the equation equal.
now we can simplify.
x=2.5
Answer:
X+4=6.5
x=2.5
Step-by-step explanation:
To find value of x, just subtract:
6.5-4=2.5
So the value of x is 2.5

Answer:
y= -45x + 380 based on how many pages are left or
y= 45x based on how much he read
Step-by-step explanation:
Anyways, lets solve with the first formula
1. A week is seven days, so substitute 7 as x.
y= -45(7)+380
-45 (7) = -45 x 7 = -315
-315+380= 65
He has 65 pages left after the week which means he has not finished the book
2. The Formula
Use the formula y=mx+b
m is the slope or the rate of change. What is affecting the constant number of 380?
The 45 pages he is reading change how many pages he has left right?
That means the 45 that is changing b is the slope or m, but it is negative because its affecting how many pages he has left in a negative way.
b is the starting value
That is 380 pages left, which is what he starts off as the slope
Hence the equation is
y=-45x+380
Answer: y= -45x + 380 based on how many pages are left or
y= 45x based on how much he read
Step-by-step explanation: 1. A week is seven days, so substitute 7 as x.
y= -45(7)+380
-45 (7) = -45 x 7 = -315 2. The Formula
Use the formula y=mx+b
m is the slope or the rate of change. What is affecting the constant number of 380?
The 45 pages he is reading change how many pages he has left right?
That means the 45 that is changing b is the slope or m, but it is negative because it's affecting how many pages he has left negatively.
b is the starting value
That is 380 pages left, which is what he starts as the slope
Hence the equation is
y=-45x+380

To create the flower gardens, Wendell bought six pieces of wood. Pieces A and B are 6 feet long, pieces C and D are 8 feet long, piece E is 3 feet long, and piece F is 2 feet long.
Answer:
Part B: They cannot make a triangular garden because in order for 3 sides to make up a triangle, 2 sides when added up have to be greater than the other side. For example, side D + E has to be greater than side F. If it was a triangle, side E + F has to be greater than side D. Since 2 + 3 < 8, this cannot be a triangle.
Step-by-step explanation:
Part C: They can make a rectangle because they can use pieces A and B for the length and pieces C and D for the width.
