Answer:

The correct option is B.

Step-by-step explanation:

Consider the diagram below.

It is a Venn diagram.

The diagram shows that all the natural numbers are contained in the set of all the whole numbers.

This implies that all natural numbers are whole numbers.

Then the statement best describing the relationship between whole numbers and natural numbers is:

(B) The diagram shows that natural numbers are a subset of whole numbers,  because all natural numbers are whole numbers.

Thus, the correct option is B.

Answer:

25%.

Step-by-step explanation:

Since there are 52 cards, and 4 suits, you must find the number of cards for each suit. Begin by dividing 52 by 4.

52 / 4 = 13.

Now, we must check how many times 13 goes into 52. It goes in 4 times (4 x 13 = 52).

Because it is exactly 52, not over, we can find the percent by dividing 100 by the number of times 13 went into 52!

Since it went in 4 times, we will get the answer with this final equation:

100 / 4 = 25.

Therefore, the answer is 25%!

Answer:

b. Exploring alternation explanation

Step-by-step explanation:

Experiments are carried out in controlled conditions to confirm a known truth, examine the validity of a hypothesis, or evaluate the efficacy of something that has never been tried before.

SO, when an experiment result seems only partly to support a hypothesis, the best thing to do is to consider exploring alternative explanations through modification of the hypothesis.

A scientific should not be formulated because it is when we have a valid theory that we can formulate a scientific law.

Also, we cannot manipulate the experiment's data because it is not part of the code and conduct of carrying out research.

Step-by-step explanation:

Surface area is the sum of the faces of all sides, so find the area of all sides and add

Answer:

40 mi²

Step-by-step explanation:

(see attached for reference)

the formula for surface area of a right rectangular prism

= 2(length x width) + 2(width x height) x 2(length x height)

in our case

length = 4 mi

width = 2 mi

height = 2 mi

substituting these values into the equation:

surface area

= 2(length x width) + 2(width x height) x 2(length x height)

=2(4)(2) + 2(2)(2) x 2(4)(2)

= 16 + 8 + 16

= 40 mi²

Answer:

distance from Irvington to Newark

.= 3 Miles

Step-by-step explanation:

distance from Irvington to Newark.= X

distance from Gillette, New Jersey, to Irvington, New Jersey,= y

Y= 1+4x

total distance from Gillette to Newark

= z

Z= 6x-2

But total distance = x+y

Total distance= x+1+4x

Total distance= 1+5x

1 +5x= 6x-2

1+2= 6x-5x

3= x

distance from Irvington to Newark.= X

distance from Irvington to Newark

.= 3 Miles

distance from Gillette, New Jersey, to Irvington, New Jersey,= 1+4x

distance from Gillette, New Jersey, to Irvington, New Jersey,= 1+4(3)

distance from Gillette, New Jersey, to Irvington, New Jersey,= 1+12

distance from Gillette, New Jersey, to Irvington, New Jersey,= 13 miles

Total distance= 1+5x

Total distance= 1+5(3)

Total distance= 16 miles

AB = 6.4

Step-by-step explanation:

Assuming that AB + BC is AC, then we can say the following:

AB + BC = AC

AB + 6.8 = 13.2

AB + 6.8 + -6.8 = 13.2 + -6.8

AB = 6.4

Answer:

Volume of shaded portion = (600 - 36π) units³

Step-by-step explanation:

Volume of the shaded portion = Volume of pyramid - Volume of cone

Volume of pyramid = ⅓*l*w*h

Where,

l = length of base of pyramid = 15 units

w = width of base of pyramid = 10 units

h = height of pyramid = 12 units

Plug in the values to find the volume of the pyramid

Volume of pyramid = ⅓*15*10*12 = 5*10*12 = 600 units³

Volume of Cone = ⅓πr²h,

Where,

r = radius = ½ of diameter = ½ of 9 = 3 units

h = height = 12 units

Volume of Cone = ⅓*π*3²*12 = ⅓*π*9*12

= π*3*12 = 36π units³

Volume of shaded portion = (600 - 36π) units³

Answer:

d

Step-by-step explanation:

The law of Sines applied to a Δ ABC is

[tex]\frac{a}{sinA}[/tex] = [tex]\frac{b}{sinB}[/tex] = [tex]\frac{c}{sinC}[/tex]

Using this in Δ HJL

[tex]\frac{z}{sinL}[/tex] = [tex]\frac{y}{sinH}[/tex] → (b)

Which may be expressed in reciprocal form as

[tex]\frac{sinL}{z}[/tex] = [tex]\frac{sinH}{y}[/tex] → (a)

Thus the law of Sines can be expressed as either (a) or (b)

Answer:

Step-by-step explanation:

x + 5 = 20

x = 15

Answer:

x=15

Step-by-step explanation:

We are given the equation:

[tex]\frac{1}{4} = \frac{5}{x+5}[/tex]

We want to solve for x. Therefore, we must isolate x on one side of the equation.

Let's begin by cross multiplying. Multiply the numerator of the first fraction by the denominator of the second. Then, multiply the denominator of the first by the numerator of the second.

[tex]1(x+5)=(4*5)[/tex]

[tex]x+5=(4*5)[/tex]

[tex]x+5=20[/tex]

5 is being added to x. The inverse of addition is subtraction, so subtract 5 from both sides of the equation.

[tex]x+5-5=20-5[/tex]

[tex]x=20-5[/tex]

[tex]x=15[/tex]

Let's check our solution. Plug 15 in for x.

[tex]\frac{1}{4} = \frac{5}{x+5}[/tex]

[tex]\frac{1}{4} = \frac{5}{15+5}[/tex]

[tex]\frac{1}{4} = \frac{5}{20}[/tex]

[tex]\frac{1}{4} = \frac{5/5}{20/5}[/tex]

[tex]\frac{1}{4} = \frac{1}{4}[/tex]

Our solution checks out, so we know it is correct.

The solution to this equation is x=15

Answer:

798980 doctors

Step-by-step explanation:

In a recent year, 26.2% of all registered doctors were female. The total number of registered doctors is 172900.

The percentage is a quantifiable way of comparing amounts with different totals. Because the percent is an equivalent fraction of the part with the whole, it is also a good way to get unknown amounts.

Percentages are basically fractions with a denominator of 100. We use the percent symbol (%) beside a number to indicate that it is a percentage. To calculate the percentage, divide the value by the total value and multiply the result by 100.

As given, 26.2%  of all registered doctors are females.

Consider, the total number of registered doctors as x

26.2% of x are females

26.2% of x is 45,300

26.2 / 100 × x = 45,300

x =  45,300 × 100 / 26.2

x = 172900.76

Therefore, the total number of registered doctors is 172900.

Answer:

8848 meters

Step-by-step explanation:

[tex]1 \: cm = 0.01\:m\\884800 = x \: m\\\\x = 884800\times 0.01\\\\x = 8848\:meters[/tex]

Answer:

The meter is the international system unit of length, here there are some conversions:

So we know 100 cm are equal to 1 meter and we have to pass the 884800 centimeters to meters.

If 1 meter is equal to 100 centimeters, to pass from meters to centimeters we multiply by 100 and from centimeters to meters we divide by 100.

In this case, we need to pass from cm to m, so we divide by 100 the altitude:

884800/100 = 8848 meters

Answer: $70.73

Step-by-step explanation:

Answer:

  (x, y, z) = (30°, 62°, 88°)

Step-by-step explanation:

The given relations are ...

  x + y + z = 180 . . . . sum of angle measures is 180°

  y + z = 5x . . . . . . . . sum of 2nd and 3rd is 5 times the first

  z = y + 26 . . . . . . . . third is 26 more than second

__

We can use the third equation to substitute into the second equation.

  y + (y +26) = 5x

  2y +26 = 5x

We can multiply the first equation by 5, then substitute for 5y and for z.

  5x +5y +5z = 5(180)

  (2y +26) +5y +5(y +26) = 900

  12y + 156 = 900 . . . simplify

  y +13 = 75 . . . . . . . . divide by 12

  y = 62

  z = y + 26 = 62 +26 = 88

  y+z = 5x = 62 +88 = 150

  x = 150/5 = 30

The angle measures are (x, y, z) = (30°, 62°, 88°).

Answer:

x=30  y=62  z=88

The solution is therefore (30,62,88).
