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)

Chen bikes 212 miles in 512 hour. What is Chen’s unit rate in miles per hour

Answers

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.

Answers

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

Answers

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

Which is the graph of x^2/9 + y^2/4 = 1

Answers

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.

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?

Answers

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.
