Name the sets of number to which each number belongs.
25/11
ON, R(natural, real numbers
O Q(rational numbers)
Q, R (rational, real numbers)
O W, R (whole, real numbers)

Answers

Answer 1

The correct answer is C. Q, R (rational, real numbers)

Explanation:

The number [tex]\frac{25}{11}[/tex] is a fraction, which means it represents proportions of a whole. This number can be classified as rational, which is represented by the letter Q because this category of numbers includes those numbers that can be represented as a fraction and the number provided is naturally a fraction. Moreover, this number is also a real number, which is a broad category of numbers represented by the letter R that includes rational numbers such as fractions. This means this number is rational and because of this, it is also real.

On the other hand, this number is not natural because this includes regular numbers such as 3, 43, or 3947 but not fractions, and it is not a whole number because a fraction does not represent a whole number but just a proportion.

You have a piggy bank containing a total of 106 coins in dimes and quarters. If the piggy bank contains $17.05, how many dimes are there in the piggy bank? There are how many dimes in the piggy bank.

Answers

Answer:

63 dimes

Step-by-step explanation:

Set up a system of equations where d is the number of dimes and q is the number of quarters:

d + q = 106

0.1d + 0.25q = 17.05

Solve by elimination by multiplying the top equation by -0.25 to eliminate q:

-0.25d - 0.25q = -26.5

0.1d + 0.25q = 17.05

Add together and solve for d:

-0.15d = -9.45

d = 63

So, there were 63 dimes in the piggy bank

A spherical bowl of radius r cm is a quarter full when 6 liters of water is poured into it.calculate correct to three significant figures, the diameter of the bowl.

Answers

Answer:

The bowl's diameter is 35.8 cm

Step-by-step explanation:

Recall that 1 liter = 1000 cubic cm ad have in mind that in order to get a diameter in cm, we would need to write the volume of the bowl in cubic cm.

if 6 liters is 1/4 of the bowl, then 4 times 6 liters must fill the bowl. That is: the volume of the sphere is 24 liters.

24 liters in cubic cm is: 24000 cubic cm

now, we need to use the formula for the volume of a sphere of radius R:

[tex]Vol=\frac{4}{3} \pi\,R^3\\24000=\frac{4}{3} \pi\,R^3\\R^3=\frac{24000\,(3)}{4\,\pi} \\R=\sqrt[3]{\frac{24000\,(3)}{4\,\pi} } \\R\approx 17.894\,\,cm[/tex]

therefore, the diameter of the bowl is twice this radius value:

[tex]Diameter\approx 17.894\,* 2=35.788\,\,cm[/tex]

this value rounded to 3 significant figures is: 35.8 cm

Two adjacent sides of a parallelogram are 6mm and 10mm respectively, and they form an angle measuring 60. Find the area of the parallelogram. ​

Answers

Answer:

51.96 mm² approximately

Step-by-step explanation:

the first thing you should know is that the area of a rectangle is base*height sin of (

the included angle i.e

Arectangle= bh sin90° since all angles of a rectangle are equal then the included angle is 90°

Arectangle= bh sin90° since sin90 is 1 we simply use the equation bh because multiplying bh by one is bh. bearing this in mind , the area of the parallelogram can be calculated as:

Aparallelogram= bh sin of sin of the included angle

Aparallelogram= bh sin of sin of the included angle Aparallelogram=6mm*10mm sin 60°

Aparallelogram= bh sin of sin of the included angle Aparallelogram=6mm*10mm sin 60°Aparallelogram=60mm² * 0.866

Aparallelogram= bh sin of sin of the included angle Aparallelogram=6mm*10mm sin 60°Aparallelogram=60mm² * 0.866Aparallelogram=51.96 mm² approximately

Suppose that the value of a stock varies each day from $11.82 to $15.17 with a uniform distribution. Find the third quartile, i.e., 75% of all days the stock is below what value?

Answers

The third quartile, or the value at which 75% of all days the stock is below, is $14.3325.

Used the formula that states,

the range of the distribution by subtracting the minimum value from the maximum value:

Range = Max value - Min value = $15.17 - $11.82 = $3.35

Given that the stock value follows a uniform distribution from $11.82 to $15.17.

Hence,

Range = $15.17 - $11.82

= $3.35

Now, the uniform distribution is symmetric, and the median (50th percentile) is the midpoint of the range,

Median = (Min value + Max value) / 2

= ($11.82 + $15.17) / 2

= $13.495

Hence, the third quartile (75th percentile);

75th percentile = Median + (0.25 × Range)

= $13.495 + (0.25 × $3.35)

= $13.495 + $0.8375

= $14.3325

What is the equation in point slope form of the line passing through (0,2) and (1,5)

Answers

Start by finding the slope of the line.

m = y2 - y1 / x2 - x1

m = 5 - 2/1 - 0 ⇒ 3/1 ⇒ 3.

So the slope of the line is 3.

This can be used with either one of our two points

to write the equation of the line in point-slope form.

So let's go with the point (0, 2).

Point-slope form is written y - y1 = m(x - x1).

Since we are using the point (0, 2), y - y1 would be y - 2.

"m" would be 3 and x1 would be 0.

So we have y - 2 = 3(x - 0).

The Brazilian free-tailed bat can travel 99 miles per hour. After sunset, a colony of bats emerges from a cave and spreads out in a circular pattern. How long before these bats cover an area of 80,000 square miles? Use π = 3.14

Answers

Answer: 1.6 hours.

Step-by-step explanation:

Ok, the speed of the bats is 99mph.

Here we can think this situation as a circle where the radius is growing at a speed of 99mph.

We assume that the initial radius is r = 0, and we can write the equation of the radius as a linear equation that depends on the time t.

r(t) = 99mi/h*t

First, let's find the radius that we need:

The area of a circle is:

A = ´pi*r^2

If we want A = 80,000 mi^2 we have:

80,000 mi^2 = 3.14*r^2

r = √(80,000 mi^2/3.14) = 159.6 mi

So the radius must be 159.6 miles.

Now, we know that the speed at which the radius increases is 99miles per hour, and we also know that:

Distance = Speed*Time.

in this case:

Distance = 159.6 mi

Speed = 99mi/h

Time = is the thing we want to find.

159.6mi = 99mi/h*T

T = 159.6mi/99mi/h = 1.6 hours.

Comment on the function

This function seems to be the linear function ...

  distance = 32×time - 16

It seems a little odd that the distance associated with time zero is negative. We usually think of distance as a positive value, whereas displacement can be a signed value.

As a rule, time is measured as positive from some reference point (the start of motion, for example). Here, we have no reason to believe that the function is intended to be defined for negative time values.
