PLEASE HELP SOON! Please answer the question and explain step by step how you got your answer. Julian is using a biking app that compares his position to a simulated biker traveling Julian's target speed. When Julian is behind the simulated biker, he has a negative position. Julian sets the simulated biker to a speed of 20 km/h. After he rides his bike for 15 minutes, Julian's app reports a position of -2 1/4 km.
What has Julian's average speed been so far?
Answer:
11 km/h
Step-by-step explanation:
What I did is found out how fast the simulated biker traveled for 15 minutes, by doing
[tex]\frac{20}{4}[/tex] = 5
Since 15 minutes is 1/4 of an hour. Or you could do 20/60 = 1/3, 1/3 being how much the biker traveled in a minute and multiply that by 15
15×[tex]\frac{1}{3}[/tex] = 5
Now we know that the biker traveled 5 km, now subtract 5 by [tex]2 \frac {1}{4}[/tex]
5 - [tex]2 \frac {1}{4}[/tex] = [tex]2 \frac {3}{4}[/tex]
Julian traveled [tex]2 \frac {3}{4}[/tex] in 15 minutes, now to find his average speed you multiply [tex]2 \frac {3}{4}[/tex] by 4 since [tex]2 \frac {3}{4}[/tex] is the distance traveled in 1/4 an hour.
[tex]2 \frac {3}{4}[/tex] × 4 = 11
11 km/h

What number is 0.01 less than 24? A: 23 B: 23.09 C: 23.9 D: 23.99
Answer: D: 23.99
Step-by-step explanation:
What number is 0.01 less than 24?
The number 0.01 less than 24 is equal to 24 - 0.01;
24 - 0.01 = 23.99
D: 23.99
Which model represents the product 3×25? (Giving brainliest.)
I think that is the answer because it says 2/5 where two rows are shaded and three more rows remain unshaded so, when you add that three and two it's altogether 5, so I think that is the answer, please check out the document I have uploaded.
Answer:
the one you are currently clicking on (you're correct :) )
Step-by-step explanation:
For the item you are currently clicking on, there are three columns--each with five rectangular sections. Each of the three columns--as we can see on the label to the left, is equal to 1. So, the five split pieces must all combine to stack up to 1. This means that 1 must be divided amongst 5 pieces, so we divide 1 by 5: 1/5.
You are trying to find the model that represents 2/5 (times 3, so it will have three rows). For the model you are clicking on, each column is showing two rectangles being there. This means that you have two sections of 1/th--or, 2/5ths present.
This means that you have the fraction of 2/5th, and you have it three times, so it represents three 2/5ths fractions, or 3 x 2/5.
(Remember, multiplication is repeated addition. So, 3 times of something means that its there 3 times, you have three 2/5ths)

Which expression represents a number that is 4 times as great as the quotient of 25 and 5?
A. (25 × 5 ) × 4
B. 4 ÷( 25 × 5)
C. 4 X ( 25 ÷ 5 )
D. ( 25 ÷ 5 ) ÷ 4
Answer:
C. 4 × ( 25 ÷ 5 )
Step-by-step explanation:
The wording "the quotient of A and B" means A÷B. A value is 4 times as great if it is multiplied by 4.

The quotient of 25 and 5 is (25 ÷ 5).
The expression that represents a value 4 times as great is this quotient multiplied by 4:

What is that answer to 6 (3/8) - 5 (5/8) ?
Answer:
[tex]-\frac{7}{8}[/tex]
Step-by-step explanation:
1) Use this rule: [tex]a \times \frac{b}{c} =\frac{ab}{c} .[/tex]
[tex]\frac{6\times3}{8} -5\times\frac{5}{8}[/tex]
2) Simplify 6 × 3 to 18.
[tex]\frac{18}{8} -5\times\frac{5}8}[/tex]
3) Simplify [tex]\frac{18}{8}[/tex] to [tex]\frac{9}{4}[/tex].
[tex]\frac{9}{4} -5\times\frac{5}{8}[/tex]
4) Use this rule: [tex]a\times\frac{b}{c}=\frac{ab}{c} .[/tex]
[tex]\frac{9}{4} -\frac{5\times5}{8}[/tex]
5) Simplify 5 × 5 to 25.

The number of pieces of popcorn in a large movie theatre popcorn bucket is normally distributed, with a mean of 1610 and a standard deviation of 10. Approximately what percentage of buckets contain between 1600 and 1620 pieces of popcorn?
Approximately 68%
Approximately 75%
Approximately 95%
Approximately 99.7%
Answer:
A. Approximately 68%
Step-by-step explanation:
The number of pieces of popcorn in a bucket is normally distributed.
Mean = μ = 1610
Standard deviation = б = 10
We know that in a normal distribution, approximately 34% of bags will fall within one standard deviation on one side. On both sides within the range of 1 standard deviation, 34 + 34 = 68 % of bags will fall.
A table of normal distribution of the mean is attached for better understanding.
Our range is:
1600 to 1620
1610 - 10 to 1610 + 10
μ ± б
mean ± 1 standard deviation
Our range is within 1 standard deviation. Hence, Approximately 68% of buckets contain between 1600 and 1620 pieces of popcorn.

Answer:
SA = 244.92² inches
Step-by-step explanation:
Basically just plug in the information given to you into the equation.
π (pi) = 3.14
r (radius) = 3 (radius is 1/2 of diameter, and the diameter is 6; half of 6 is 3 so that is the radius)
h (height) = 10
Therefore your equation set up should look like:
2(3.14)(3²) + 2(3.14)(3)(10) = 244.92

The figure created with the points (-2, -3), (-2, 5), (1, -3) and (1, 5) is a rectangle.
Which shape is a rectangle?
A rectangle is oblong. It has two pairs of parallel sides and four right angles. A rectangle can also be known as an equiangular quadrilateral. This is because a rectangle is a quadrilateral shape (4-sided shape) that hasparallel sides, equal to one another, and all 4 corners have angles that are90º.
