Chen bikes 212 miles in 512 hour. What is Chen’s unit rate in miles per hour
Answer:
Unit rate = 0.414 mph
Step-by-step explanation:
Distance travelled = 212 miles
Time taken = 512 hours
[tex]Unit \: rate = \frac{distance \: travelled}{time \: taken} \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{212}{512} \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 0.414 \: mph (miles \: per \: hour)[/tex]
Answer:
53/128 mph
Step-by-step explanation:
Unit rate is essentially just asking for the number of miles Chen can bike in only 1 hour. That's what "unit" means - 1.
Here, we know that Chen can bike 212 miles in 512 hours, so let's set up a proportion:
[tex]\frac{212mi}{512hr} =\frac{x}{1hr}[/tex] , where x is the number of miles Chen can bike in 1 hour
Cross multiply:
512x = 212
Divide by 512:
x = 212 / 512 = 53/128 miles
So, Chen's unit rate is 53/128 mph.
Nandini makes 'halwa' one evening and divides it into four equal portions for her family of four. However, just as they are about to eat it, an unexpected guest arrives and Nandini has to now re-divide the halwa into five equal portions. By what percentage has each family member's share reduced due to this?
Answer:
5%
Step-by-step explanation:
We know that when there are four people, then each person gets 25% of the halwa. However, when the fifth person comes, they have everyone including the guest get 20% of the halwa. In this way, the original four people are losing 5% of their halwa in order for the fifth person to get his piece

Which is the graph of x^2/9 + y^2/4 = 1
Answer:
Step-by-step explanation:
it is an ellipse.
The graph of the ellipse (x²/3²) + (y²/2²) = 1 is given in the image below.
What is an ellipse?An ellipse is a closed curve in a plane that is symmetric around two perpendicular lines known as the ellipse's axis.
The given equation is in the standard form of the equation of an ellipse centered at the origin with its major axis on the x-axis and its minor axis on the y-axis:
(x²/3²) + (y²/2²) = 1
The square of the semi-major axis (a) is 3² = 9, so the semi-major axis is a = 3.
The square of the semi-minor axis (b) is 2² = 4, so the semi-minor axis is b = 2.
Therefore, the characteristic of the given ellipse is:
a²- b² = 9 - 4 = 5
So the characteristic of the ellipse is 5.

degrees
Answer:Angle B is 44 Degrees
Step-by-step explanation: Angle C intersects the circle at the endpoints of a diameter, it intercepts an arc of 180 degrees
The measure of an inscribed angle is half the measure of its intercepted arc, so we know that the measure of angle C is 90 degrees
The angles of triangle ABC must add up to 180 degrees
m∠A+m∠B+m∠C=180
46+m∠B+90=180
m∠B+136=180
m∠B=44
The measure of Angle B in the given diagram is 44 Degrees
Angle C intersects the circle at the endpoints of a diameter, it intercepts an arc of 180 degrees
The measure of an inscribed angle is half the measure of its intercepted arc, so we know that the measure of angle C is 90 degrees
What is the sum of the angles in a triangle?The angles of triangle ABC must add up to 180 degrees.
The total sum of the angle in triangles is180 degrees.
m∠A+m∠B+m∠C=180
46+m∠B+90=180
m∠B+136=180
m∠B=44
Therefore, The measure of Angle B in the given diagram is 44 Degrees.

Find the midpoint of a line segment starting from the origin and ending at (–8, 0).
Question 6 options:
A)
(0, 0)
B)
(–16, 0)
C)
(0, –4)
D)
(–4, 0)
Answer:
Option D
-4, 0
Step-by-step explanation:
We will first of all identify the coordinates we are dealing with here.
The coordinates for this question (x,y) are: (0,0) and (-8,0)
The next thing we will do is get the formula for finding mid points of line segments.
This is [tex](\frac{x_{1}+x_{2}}{2}, )(\frac{y_{1}+y_{2}}{2}, )[/tex]
Next we will substitute the values of x 1 ,x 2, y 1, and y 2 into the equation.
We will have
[tex](\frac{0+(-8)}{2}, )(\frac{0+0}{2}, )=(-4, 0)[/tex]
Hence the coordinates of the midpoint is (-4,0)

You placed each of these cards in a brown paper bag and randomly select one and then record your results. After each selection, you place it back in the bag and select another. You do this for a total of 50 times and your results are: 6 times you picked the ace, 14 times you picked the 2, 13 times you picked the 3, 4 times you picked the 4, and 13 times you picked the 5. After looking at your results, what is the experimental probability of selecting the 4? Hint: You may have to reduce. *
Answer:
The experimenta probability of picking a 4 is [tex]\frac{4}{50}[/tex]
Step-by-step explanation:
To determine the experimental probability, we just need to divide the number of observations of the specific event by the total number of trials. In this case, we are interested in the event "picking a 4 card". This event happened 4 times. We have a total number of trials of 50. So , the experimental probability is

What’s - 46.15 as a mixed number
Answer: -46 15/100
Explanation: (see pic attached)
Answer:
46 3/20
Step-by-step explanation:
Rewrite the decimal number as a fraction with 1 in the denominator
46.15=46.15/1
Multiply to remove 2 decimal places. Here, you multiply top and bottom by 10^2 = 100
46.15/1 x 100/100= 4615/100
Find the Greatest Common Factor (GCF) of 4615 and 100, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 5
4615/100 divided by 5/5= 923/20
Simplify the improper fraction
46 3/20
In conclusion
46.15= 46 3/20

A trail mix consist of 7 3/4 oz of sunflower seeds, 9 1/4 oz of raisins, 4 1/4 oz of walnuts, and 7 1/2 oz of soybeans. If the mix is split equally between eight hikers, how much would each one get?
Answer:
Each biker gets 3 19/32 of the mix.
Step-by-step explanation:
In the questions, we are told that a trail mix consist
7 3/4 oz of sunflower seeds,
9 1/4 oz of raisins
4 1/4 oz of walnuts
7 1/2 oz of soybeans
Step 1
Add up every element in the trail mix
We have are given mixed numbers which is made up of whole number and a proper fraction
7 3/4 oz + 9 1/4 oz + 4 1/4 oz + 7 1/2 oz
So we add up the whole numbers first
27 + ( 3/4 oz + 1/4 oz + 1/4 oz + 1/2 oz)
Next, We find the lowest common multiple of the denominators of the proper fractions which is 4
= 27 + ((3×1) + (1×1) + (1×1) +(1×2)/4)
27 + (3+1+1+2) / 4
27 + 7/4
27 + 1 3/4
27 + 1 + 3/4
Total mix = 28 3/4
Step 2
If the mix is split equally between eight hikers, how much would each one get?
We would convert 28 3/4 into an improper fraction and divide it by 8 bikers
115/4 ÷ 8
115/ 4 × 1/8
= 115/32
Turning it into a mixed fraction, we have:
3 19/32
Therefore, each biker gets 3 19/32 of the mix.

Answer:
You'll need the attached formula.
Total = Principal * e ^ (rate * years)
rate = .04
Total = 2,000 * 2.718281828 ^ (.04 * 8)
Total = 2,000 * 2.718281828 ^ (.32)
