Answer:

  70 m

Step-by-step explanation:

Perhaps you want to evaluate the expression:

  [tex]\dfrac{7\text{ cm}}{1\text{ yr}}\cdot 1000\text{ yr}=7000\text{ cm}=70\text{ m}[/tex]

__

There are 100 cm in 1 m. The units of yr cancel.

Answer:

[tex] \red{ \bold{ V = \sqrt{\frac{2(E - mgh)}{M}}}}[/tex]

Step-by-step explanation:

[tex]E = MV^2 ÷ 2 + mgh \\ \\ E - mgh = MV^2 ÷ 2 \\ \\ 2(E - mgh)= MV^2 \\ \\ \frac{2(E - mgh)}{M}=V^2 \\ \\ \sqrt{\frac{2(E - mgh)}{M}} = V \\ \\ \red{ \bold{ V = \sqrt{\frac{2(E - mgh)}{M}}}}[/tex]

Step-by-step explanation:

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

Explanation:

To get this answer, we double the 71.40 to get 142.80

You can think of it like an equation and we multiply both sides by 2

4 jeans = 71.40 dollars

2*(4 jeans) = 2*(71.40 dollars)

8 jeans = 142.80 dollars

------------

Or you could solve it like this

(4 jeans)/(71.40 dollars) = (8 jeans)/(x dollars)

4/71.40 = 8/x

4x = 71.40*8

4x = 571.2

x = 571.2/4

x = 142.80

------------

Yet another way to solve is to first find the unit rate

4 jeans cost 71.40, so that must mean 1 pair of jeans cost 71.40/4 = 17.85 dollars. This is the unit rate since "unit" means "one". It's the price per pair of jeans.

Multiply that by 8 to find out how much 8 pairs will cost, and we get 17.85*8 = 142.80

Answer:

√3

Step-by-step explanation:

Using the pythagorean theorem, we know that a^2 + b^2 = c^2

In this case, c = 2, which means that a^2 + b^2 = 4

Since we know that a = 1, this means that a^2 is also 1. So, we know that b^2 = 4 - 1

Therefore, b^2 = 3

So, the answer is square root 3

Simply plug in the 2 coordinates into the slope formula to find slope m

Step-by-step explanation:

start by adding like terms which would gice us

3x+5x=8x so,

8x=32 divide by 8 on both sides so we leave x by itself giving us x=4

Add the 21 then divide by 2

Answer:

x = 16, x = -7

Step-by-step explanation:

The question is;

35 * 4 = ( x - 7 ) ( x - 3 )

Combine like terms on one side;

140 = ( x - 7 ) ( x - 3 )

Distribute, remember to multiply every term with one another;

140 = [tex]x^{2}[/tex] - 3x - 7x + 21

Combine like terms;

140 = [tex]x^{2}[/tex] - 10x + 21

Inverse operations;

140 = [tex]x^{2}[/tex] - 10x + 21

-21                  -21

119 = [tex]x^{2}[/tex] - 10x

Factor;

119 = x ( x - 10 )

At this point it is fairly obvious that;

x = 16, x = -7

Note; One could have used a multitude of methods to solve this problem, one could have factored, completed the square, or used the quadratic formula, this method was simply chosen because it is easy to explain

The solution to the equation 2 = -(7/4) + (1/4)x is x = 15

An equation is an expression used to show the relationship between two or more numbers and variables.

Given the equation:

2 = -(7/4) + (1/4)x

Add 7/4 to both sides of the equation:

2 + 7/4 = -(7/4) + (1/4)x + 7/4

(1/4)x = 15/4

Multiply both sides by 4:

x = 15

The solution to the equation 2 = -(7/4) + (1/4)x is x = 15

Answer:

No solutions

Step-by-step explanation:

4(2r + 3) = 15r - 11 + 1 - 7r

Distribute:

8r + 12 = 15r - 11 + 1 - 7r

Combine like terms:

8r + 12 = 8r - 10

Same to both sides:

0r = -22

The coefficients are 4, 5 and 7

There is no constant

The second one is right

Answer:

Coefficient: 4,5,7 and Constant: None

Step-by-step explanation:

A coefficient can be defined as the number next to the variable or unknown numbers

This would be 4, 5, and 7

However, there does not seem to be a constant, which is a value that should not be the coefficient of a variable.

Answer:

x+18=90-x

use this equation and solve

2x=72

x=36

36+18=54

90-54=36

54 degrees and 36 degrees

The solution is,  the measure of an angle and its complement are, 54 degrees and 36 degrees.

In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle. The two rays are called the sides of an angle, and the common endpoint is called the vertex.

We know that, a ray is a line that continues on forever inn one direction with a point at it's start.

here, we have,

let, one angle = x

x+18=90-x

use this equation and solve

2x=72

x=36

so, we get,

36+18=54

90-54=36

Hence, The solution is,  the measure of an angle and its complement are, 54 degrees and 36 degrees.

Answer:

slope = 2, y- intercept = - 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 4 + 2x , that is

y = 2x - 4 ← is in slope- intercept form

with slope m = 2 and y- intercept c = - 4
