Rational or Irrational?
4 x 10^-9
(Four times ten to the negative ninth power)

Answer:

39

Step-by-step explanation:

Square Area

8-3 to get the right side of the square which equals 5. So the square is 5*6=30

Triangle Area

To get the area of a triangle the formula is a=b*h*1/2, so base is 3 and height is 3, we would do 3*3*1/2 which equals 4.5

but you have 2 triangles so multiply 4.5*2 and that's 9.

Conclusion

So, 30+9=39

Answer:

  4mn/(3m+12)

Step-by-step explanation:

It is often helpful to factor expressions so that common factors can cancel.

  \(\dfrac{8n^2}{m^2-16}\times\dfrac{m^2-4m}{6n}=\dfrac{8mn^2(m-4)}{6n(m-4)(m+4)}=\dfrac{4mn}{3(m+4)}\\\\=\boxed{\dfrac{4mn}{3m+12}}\)

Answer: 1,983.75

First option

Step-by-step explanation:

In order to find markup you convert the percentage to a decimal: 0.15.

You multiply 1725 by 0.15 and you get 258.75. This is the markup. In order to get the total cost, you add the original price with the markup price.

1725 ( original price ) x 258.75 ( markup price ) = 1,983.75 ( total cost with the markup )

The angle measures of J and L are given as follows:

m < J = m < L = 65º.

To obtain the angle measures, we must considering that the sum of the measures of the internal angles of a triangle is of 180º.

The internal angles for this problem are given as follows:

Angles J and L are congruent, meaning that they have the same measure, which is obtained as follows:

50 + x + x = 180

2x = 130

x = 65º.

A power is two numbers that one is the base and the other is the power.

To calculate a power fraction, both the numerator and the denominator are multiplied the same, so:

\(\boldsymbol{\sf{\left(\dfrac{5}{6}\right)^{2}=\dfrac{5\times5}{6\times6}=\dfrac{25}{36} }}\)

Since the fraction 25/36 does not have a half, that is, it is already in reduced form, so it is no longer possible to simplify it.

Answer:

Derions answer is not correct becuase 500 x 0.015=7.5 inches.  If he got this as an answer that would meen that the stack of paper is 7.5 inches tall, which is not correct.  

If we divide 1.875 by 500 we get 0.00375 which is the thickness of each sheet of paper.

Answer:

0.18 cm²

Step-by-step explanation:

Given that a rectangle and a triangle have same perimeter . The sides of them are ,

\(\begin{cases} Square = 4cm , 4cm , 3cm \ and \ 3cm .\\ Triangle = 4cm , 5.8cm \ and \ 4.2cm \end{cases}\)

We know that area of rectangle is product of length and breadth.

\(\implies Area = length \times breadth \\\\\implies Area = 4cm \times 3cm\\\\\implies \red{ Area = 12cm^2}\)

Also we know that the area of triange is half the product of base and height . So that ,

\(\implies Area = \dfrac{1}{2}\times 5.8cm \times 4.2 cm \\\\\implies \red{ Area = 12.18 cm^2 }\)

Therefore the difference between them is ,

\(\implies D = A_1 - A_1 \\\\\implies D = 12.18cm^2-12cm^2 \\\\\implies \red{D = 0.18 cm^2}\)

Answer:

\( - 2 \frac{3}{5} \div \frac{3}{5} = - \frac{13}{5} \times \frac{5}{3} = - \frac{13}{3} = - 4 \frac{1}{3} \)

\(2 \frac{1}{4} \div \frac{3}{4} = \frac{9}{4} \times \frac{4}{3} = 3\)

\( - \frac{10}{17} \div ( - \frac{15}{17} ) =\)

\( - \frac{10}{17} \times ( - \frac{17}{15} ) = \frac{2}{3} \)

\( 2.75 \div ( - 2.2) = \)

\( 2 \frac{3}{4} \div ( - 2 \frac{1}{5} ) = \)

\( \frac{11}{4} \div ( - \frac{11}{5} ) = \frac{11}{4} \times ( - \frac{5}{11} ) = - \frac{5}{4} = - 1.25\)

3 ⇒ 2 (1/4) / (3/4)

-1.25 ⇒ 2.75 / (-2.2)

2/3 ⇒ (-10/17) / (-15/17)

-4 1/3 ⇒ -2 (3/5) / (3/5)

Answer:

(64-32)/4=8

Step-by-step explanation:

Answer:

Step-by-step explanation:

The number of those line segments which have endpoints of different colors is 47.

What is permutation and combination?

A permutation is the number of different ways a set can be organized; order matters in permutations, but not in combinations.

We have:

There are 5 red, 4 green, and 3 blue points on a circle.

There are different colored endpoints on each line segment that starts at a red point and travels to either a green point or a blue point.

There are 5 red points and 7 segments from each of them, making a total of 35 segments.

There are different colored endpoints on each line segment that leaves at a green point and travels to either a red or blue point.

There are 4 green points and 8 segments from each, for a total of 32 segments.

There are different colored endpoints on each line segment that leaves at a blue point and travels to either a green point or a red point.

Each blue point has 9 segments, and there are a total of 5 blue points.

Add all the ways = 35 + 32+ 27

= 94 segments.

Number of segment = 94/2 = 47

Thus, the number of those line segments which have endpoints of different colors is 47.

Answer:

Step-by-step explanation:

Challenge 1

We have exponential decline if 0 b 1. As you move from left to right, the curve will get less steep.

If b is greater than 1, exponential growth is present, and the curve slopes upward from left to right.

Examples include exponential decline (y = 2(0.5)x) and exponential growth (y = 2(1.2)x).

Remember that b cannot be negative.

===========================================

Challenge 2

In the general template provided, enter x = 0.

y = a(b)^x

y = a(b)^0

y = a(1) (1)

y = a

When x = 0 is plugged in, the result is y = a.

The curve is therefore on the point (0,a). The y intercept appears here. It is the point when the curve veers off the y axis. The y intercept is altered if the value of "a" is altered.

Answer:

a=3/4

Step-by-step explanation:

1. Get 2/3a by itself.

•Turn 1/3 to 2/6 by multiplying 1/3 by 2/2.

•Because you only add and subtract like denominators

This will make it look like:

2/3a - 1/6 = 2/6

Then, add 1/6 to both sides to get 2/3a by itself.

It'll look like this:

2/3a = 3/6

2. Get a by itself.

•Multiply the reciprocal (opposite) of 2/3 to get a alone.

This will look like:

(3/2) • 2/3a = (3/2) • 3/6

a = 18/24

3. Simplify.

Find the largest number that can simplify the equation.

For example, 18 ÷ 3 = 6, and 24 ÷ 3 = 8.

But the largest number you can divide both sides by is 6.

18 ÷ 6 = 3 and 24 ÷ 6 = 4.

3/4.
