Answer:

false; Only square roots can result in irrational numbers. Subtraction of any two real numbers results in a rational number.

Step-by-step explanation:

Rational numbers in any operation with a rational number except square rooting will result in a rational number.

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:

0.1949

Step-by-step explanation:

Given a normal distribution with;

Mean(m) = 8.8 inches

Standard deviation (sd) = 0.7 inches

If one item is chosen at random, what is the probability that it is less than 8.2 inches long?

Find the Z-score :

x = 8.2 inches

Z = (x - m) / sd

Zscore = (8.2 - 8.8) / 0.7

Zscore = - 0.6 / 0.7

Zscore = - 0.857 = - 0.86

P(Z < - 0.86) :

From z distribution table :

P(Z < - 0.86) = 0.1949

If one item is chosen at random, there is a probability of 0.1949 that it will be less than 8.2 inches long.

Answer: $70.73

Step-by-step explanation:

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:

3 customers brought all the three papers.

Step-by-step explanation:

Let, D, O and N represents the three newspapers.

D = The daily times

O = The observer

N = The new Nigeria.

According to the given information,

[tex]n(D\cup O\cup N)=135, n(D)=70,n(O)=60,n(N)=50[/tex]

[tex]n(D\cap O)=17, n(O\cap N)=15, n(D\cap N)=16[/tex]

We know that,

[tex]n(A\cup B\cup C) = n(A) + n(B) + n(C)-n(A\cap B)-n(B\cap C)-n(C\cap A) + n(A\cap B\cap C)[/tex]

Using this formula, we get

[tex]n(D\cup O\cup N) = n(D)+n(O) + n(N)-n(D\cap O)-n(O\cap N)-n(N\cap D) + n(D\cap O\cap N)[/tex]

[tex]135 =70+60+50-17-15-16 +n(D\cap O\cap N)[/tex]

[tex]135 =132+n(D\cap O\cap N)[/tex]

[tex]135 -132=n(D\cap O\cap N)[/tex]

[tex]3=n(D\cap O\cap N)[/tex]

Therefore, 3 customers brought all the three papers.

Answer:

D

Step-by-step explanation:

First, let's define each of the terms.

Scalene refers to triangles whose three sides and three angles all have different measures.

Isosceles refers to triangles who has two equivalent angles and sides.

Right triangles are triangles with one right angle.

So we know that the triangle has one 90 degrees and 2 45 degree angles.

In other words, this is an isosceles triangle.

And since it also contains a 90 degree angle, it means that the triangle is an isosceles right.

The answer is D

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

Step-by-step explanation:

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

Answer:

The set of solutions are linearly independent because the wronskian is

e^(2ax) ≠ 0

Step-by-step explanation:

To show that the set of solutions {e^(ax), xe^(ax)} are linearly independent, we find the Wronskian of the set of solutions.

Wronskian of y1 and y2 is given as:

W(y1, y2) = y1y2' - y1'y2

y1 = e^(ax)

y1' = ae^(ax)

y2 = xe^(ax)

y2' = axe^(ax) + e^(ax)

W(y1, y2) = e^(ax)[axe^(ax) + e^(ax)] - ae^(ax).xe^(ax)

= (ax + 1)e^(2ax) - axe^(2ax)

= e^(2ax)

The wronskian of the given set of solutions is e^(2ax), which is not zero.

Because it is not zero, the set of solutions are linearly independent.

The volume of a sphere is given by the expression:

where R = radius

So

V = (4πR³)/3

V = (4.π.12³)/3

V = (4.π.1728)/3

V = 6912π/3

or

V = 7,238.23cm³

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:

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:

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:

  2300

Step-by-step explanation:

When you multiply by 10, each place value moves one to the left: hundreds become thousands, tens become hundreds.

(2 hundreds 3 tens) × 10 = 2 thousands 3 hundreds

In numbers (standard form), this is ...

  230 × 10 = 2300

(a) Area of rectangle = 1.67 squares in

(b) Area of rectangle = 3.33 squares in

(c) Area of rectangle = 6.67 squares in

(d) Area of rectangle = 0.53 squares in

(e) Area of rectangle = 1 squares in

The area of a rectangle is defined as the product of the length and width.

(a) Length of rectangle =  5 in and

Width of rectangle =  1/3 in

Area of rectangle = 5 × 1/3 = 5/3 = 1.67 square in

(b) Length of rectangle =  5/2 in and

Width of rectangle =  4/3 in

Area of rectangle = 5/2 × 4/3 = 20/6 = 3.33 square in

(c) Length of rectangle =  5 in and

Width of rectangle = 4/3 in

Area of rectangle = 5 × 4/3 = 20/3 = 6.67 square in

(d) Length of rectangle =  2/5 in and

Width of rectangle = 4/3 in

Area of rectangle = 2/5 × 4/3 = 8/15 = 0.53 square in

(e) Length of rectangle =  7/6 in and

Width of rectangle = 6/7 in

Area of rectangle = 7/6 × 6/7 = 42/42 = 1 square in

Answer:

24

Step-by-step explanation:

The most important thing to note here is that there are no parentheses defining what to do when.

Therefore, we have to use order of operations - PEMDAS, to find the expression's value.

PEMDAS states that the order you go in is:

1. Parentheses

2. Exponents

3. Multiplication/Division

4. Addition/Subtraction

[tex]6^2-3\cdot4[/tex]

There are no parentheses, so first we have to solve the exponent.

[tex]6^2=36\\\\36-3\cdot4[/tex]

Now we have to multiply.

[tex]36-12[/tex]

And now subtract.
