What is 13.7 billion years in scientific notation​

Answer: 8

Step-by-step explanation: Usually you should use prime factorization or the “ladder” method; however, with questions like this that have small, easy numbers, you can simply think about it. Every number’s largest factor is itself, which means that 8 is at least a factor of 8. We also know that 8 times 2 equals 16, hence, the greatest common factor is 8.

Distance = rate x time

Distance = 60 x 3

Distance = 180 miles.

Answer:

180m

Step-by-step explanation:

d= distance traveled => ?m

r= rate => 60m/h

t= time => 3h

Formula=> d=r.t

>d= 60 x 3=> d= 180m

So

d= distance traveled => 180m

r= rate => 60m/h

t= time => 3h

Answer:  4 3/8 ≈ 4.38

Step-by-step explanation:

To start off, note that 4 3/8 is a mixed number, also known as a mixed fraction. It has a whole number and a fractional number. We have labeled the parts of the mixed number below so it is easier to follow along.

4 = Whole number

3 = Numerator

8 = Denominator

To get 4 3/8 in decimal form, we basically convert the mixed number to a fraction and then we divide the numerator of the fraction by the denominator of the fraction.Step 1: Multiply the whole number by the denominator:

4 × 8 = 32

Step 2: Add the product you got in Step 1 to the numerator:

32 + 3 = 35

Step 3: Divide the sum from Step 2 by the denominator:

35 ÷ 8 = 4.375

That's it folks! The answer to 4 3/8 in decimal form is displayed below:

Mikel gave a \$1.32$1.32dollar sign, 1, point, 32 tip for an order that cost \$8.80$8.80dollar sign, 8, point, 80. Determine whether or not each tip below is proportional to Mikel's tip. Proportional to Mikel's tip Not proportional to Mikel's tip

1.) \$2.22$2.22dollar sign, 2, point, 22 tip for a \$14.80$14.80dollar sign, 14, point, 80 order

2.) \$1.86$1.86dollar sign, 1, point, 86 tip for a \$10.50$10.50dollar sign, 10, point, 50 order

3.) \$0.78$0.78dollar sign, 0, point, 78 tip for a \$5.20$5.20dollar sign, 5, point, 20 order

Answers

1) proportional to Mike's tip

2) Not proportional to Mike's tip

3) proportional to Mike's tip

Step-by-step explanation:

when two things have the same relative sides, they are said to be proportional.

To determine if the other tips are proportional to Mikel's tip, we will, first of all, determine the size of Mikel's tip, then compare the other tips with it.

Mikel's tip:

$1.32 for $8.80

= [tex]\frac{1.32}{8.80}= 0.15[/tex]

Now, let us compare this with the other tips

1.) $2.22 for 14.80

= [tex]\frac{2.22}{14.80} = 0.15[/tex]

proportional to Mike's tip

2.) $1.86 for $10.50

[tex]\frac{1.86}{10.50} = 0.177\\0.177 \neq 0.15[/tex]

Not proportional to Mike's tip

3.) $0.78 for $5.20

= [tex]\frac{0.78}{5.20} = 0.15[/tex]

proportional to Mike's tip

Answer: D

Step-by-step explanation:

Answer:

d) People per hour, because the dependent quantity is the people

Step-by-step explanation:

In this situation, the two quantities are people and hours. These are the two things in this problem we can count or measure.

The independent variable is the one that causes a change, while the dependent variable is the one that gets changed. In this situation, the number of people change every hour; this means the number of people gets changed, which makes it the dependent variable. This means that the independent variable must be time.

Since people is dependent and time is independent, "people per hour" would be the best form of this statement.

Answer:

x=5/3

Step-by-step explanation:

3x+2=7

3x=7-2

3x=5

divide

x=5/3

Answer:

x = - 5

Step-by-step explanation:

Given

[tex]\frac{2x-20}{3}[/tex] = 2x ( multiply both sides by 3 to clear the fraction )

2x - 20 = 6x ( subtract 2x from both sides )

- 20 = 4x ( divide both sides by 4 )

- 5 = x , that is x = - 5

Answer: 28

Step-by-step explanation:

To find g(5) input 5 into the 5 and solve

g(5) = 5^2 + 3  

g(5) = 25 + 3

g(5) = 28

Step-by-step explanation:

The cylinder is a closed figure which consists of two circular ends. If r is the radius and h is the height of the cylinder, then its surface area is given by :

[tex]A=2\pi rh[/tex]

or

[tex]A=2\pi \times r\times h[/tex]

We also know that, surface area = perimeter×height

So, the surface area of the cylinder is the product of circumference of the circle and height of the cylinder.

I'm pretty sure 2 and 5

Step-by-step explanation:

Hope this helps :)

A one solution because it's x=1

this is the original problem

8x-3=3x+2

we want to have x by itself so. . .

we add three on both sides. it cancels -3. And 2+3=5

8x=3x+5

we subtract 3x on both sides so 8x-3x=5x and 3x cancels on the other side

5x=5

we divide by 5 on both sides to get x by itself

x=1

if it was 1=1 or x=x (the same on both side) it would've been infinite solutions. if the numbers didn't match like 4=6 it would've been no solution

To see if 6 is a factor of 18, we need to take the quotient between 18 and 6 and see if it is an integer, so the correct option is C.

We say that the number a is a factor of b if and only if a divides b.

This means that the quotient:

b/a =  integer number.

Then, to see if 6 is a factor of 18, we need to divide 18 by 6, and see if the quotient is an integer number.

We will get:

18/6 = 3

3 is an integer number, so yes, 6 is a factor of 18.

From this, we can conclude that the correct option is C.

Answer:

125

Step-by-step explanation:

500 times 0.25 equals 125.

Answer:125

Step-by-step explanation:

The slope of the point (12,-2) and (4,-6) is; 1/2

The equation of the straight line has its slope and given point.

If we have a non-vertical line that passes through any point(x1, y1) and has a gradient m. then general point (x, y) must satisfy the equation;

y-y₁ = m(x-x₁)

we have been given two points (12,-2) and (4,-6).

Then the slope is;

m = (-6 - (-2))/ (4 - 12)

m = -4 / -8

m = 1/2

The equation of line is y + 2 = 1/2(x - 12)

Hence, the slope of the point (12,-2) and (4,-6) is 1/2.

Answer:

.018 Kg/cm^3

Step-by-step explanation:

[tex]p = m \div v \\ [/tex]

Density (P) is equal to the mass (9.9g) divided by volume (.55cm^3)

[tex] = 9.9 \div .55[/tex]

= 18g/cm^3

=.018kg/cm^3

The density with given mass and volume is 18 g/cm³.

Density is the measurement of how tightly a material is packed together. It is defined as the mass per unit volume.

Given that, a gold earring has a volume of 0.55 cubic centimeters and a mass of 9.9 grams.

We know that, density =Mass/Volume

Density = 9.9/0.55

= 18 g/cm³

Therefore, the density with given mass and volume is 18 g/cm³.

Answer:

B

Step-by-step explanation:

A rational number can be expressed in the form

[tex]\frac{a}{b}[/tex] ← where a and b are integers

From the set

3 is rational as it can be expressed as [tex]\frac{3}{1}[/tex]

and [tex]\sqrt{9}[/tex] = 3 ← rational

[tex]\sqrt{2}[/tex], [tex]\sqrt{3}[/tex] and [tex]\sqrt{7}[/tex] ← are irrational numbers

Thus there are 2 rational numbers out of the 5 given, thus

P( rational ) = [tex]\frac{2}{5}[/tex] → B
