Answer:

y-25 = 2(x-10)

Step-by-step explanation:

First find the slope using the points (10,25) and (20,45)

m = ( y2-y1)/(x2-x1)

m = (45 - 25)/(20-10)

   = 20/10

   = 2

Then using point slope form of a line

y-y1 = m(x-x1)

y-25 = 2(x-10)

Answer:

x = 14

Step-by-step explanation:

let the number be x.

now,

Given that,

4x + 10 = 5x - 4

moving all x terms to the LHS and the constants to the RHS

4x - 5x = -4 - 10

-x = -14

dividing both sides by -1

x = 14

Answer:

Answer:

x = V(X + 8) + 4

Step-by-step explanation:

Switch sides

x - 4 = V(X + 8\)

Add\ 4 to both sides

x - 4 + 4 = V(X + 8\) + 4

Simplify

x = V(X + 8) + 4

participatory design

Step-by-step explanation:

Participatory Design (PD) is defined as an approach that is used for assessment as well as design and development of the technological and the organizational systems.

This method is used to a control and the experimental groups that is as similar as possible. Therefore the participants served their own control group. And so rather than replying the random assignment to produce an equal groups, the researchers have the same group of the participants that experience various conditions in the study.

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

Explanation:

Since L and M are parallel lines, this means x+y = 180 due to the same side interior angles theorem. Some books refer to these angles as consecutive interior angles.

If x+y = 180, then y = 180-x.

Plug this into the equation your teacher gave you

x/y = 3/7

x/(180-x) = 3/7

7x = 3(180-x) ... cross multiply

7x = 540 - 3x

7x+3x = 540

10x = 540

x = 540/10

x = 54

Use this to find y

y = 180-x

y = 180-54

y = 126

Then notice how x/y = 54/126 = 3/7, which helps confirm we have the correct x and y values.

Divide both parts of the first fraction by 18 to fully reduce.

Now because angles y and z are alternate exterior angles, this must mean z = y = 126 degrees

The volume of square based pyramid is 4cm³.

A square pyramid is a pyramid, in geometry, that has a square base and four lateral faces.

To find the volume of a pyramid, we multiply the area of its base with the height of the pyramid, and divide by 3.

V=1/ 3×B²×h

where B is the area of the base of the pyramid, and h is its height.

Now in the question,

b = 2cm; h = 3cm

Volume = (1/3 x 2x2x3)cm³

= (1x2x2)cm³

= 4cm³

Therefore, the volume of square based pyramid is 4cm³

80 square meters of wallpaper must be sold.

Algebra is the branch of mathematics that helps in the representation of problems or situations in the form of mathematical expressions. it involves variables like x, y, z, and mathematical operations like addition, subtraction, multiplication, and division to form a meaningful mathematical expression.

Given:

R = y² - 65y.

Now, R= 1200

y² - 65y = 1200

y² - 65y -1200 = 0

y² - 80y + 15y -1200 = 0

(y- 80) (y + 15)= 0

y= 80, -15

Hence, 80 square meters of wallpaper must be sold if the revenue from the wallpaper is to be 1200 per day.

Answer:

x = 11

Step-by-step explanation:

The diagonals of a rhombus are perpendicular meaning that they create 90 degree angles

If they create 90 degree angles then 7x + 13 = 90

( Note that we've just created an equation that we can use to solve for x )

We now solve for x algebraically using the equation we created

7x + 13 = 90

Step 1 Subtract 13 from both sides

7x = 77

Divide both sides by 7

x = 11

Answer:

80

Step-by-step explanation:

The value of x must be greater than 77

The only number greater than 77 is 80

7235 using 3.14 for pi

7238 using the pi button

Step-by-step explanation:

The volume of a sphere is given by

V = 4/3 pi r^3

V = 4/3 pi (12)^3

V = 2304pi

Letting pi = 3.14

V = 7234.56 and rounding to a whole number

V = 7235

Using the pi button

V =7238.22947 and rounding to a whole number

V = 7238

Answer: 7238

Step-by-step explanation:

The formula used is 4/3πr³

Now let's substitute the radius: 12

4/3πr³

=4/3×π×12³

=4/3×π×1728

=7238.22947

but since we are rounding it to the nearest whole number the answer would be 7238

Answer:

The mass of Sun is [tex]65\times 10^5[/tex] times greater than mass of Mercury.

Step-by-step explanation:

We are given that

Mass of the sun=[tex]M=2.13525\times 10^{30}[/tex] kg

Mass of Mercury, [tex]m=3.285\times 10^{23}[/tex]kg

We have to find how many times greater is the mass of the sun than the mass of Mercury.

Mass of sun/Mass of mercury=[tex]\frac{2.13525\times 10^{30}}{3.285\times 10^{23}}[/tex]

Mass of sun/Mass of mercury[tex]=0.65\times 10^{30-23}[/tex]

Using the property

[tex]a^x/a^y=a^{x-y}[/tex]

Mass of sun/Mass of mercury[tex]=0.65\times 10^{7}[/tex]

Mass of sun/Mass of mercury[tex]=65\times 10^5[/tex]

Mass of Sun=[tex]65\times 10^5[/tex] times Mass of Mercury

Answer:

s = 6

Step-by-step explanation:

It's equal to the other leg, since it's an equilateral triangle, where two angles are 45°

Answered by GAUTHMATH

The length of s is 6 units.

The correct option is C.

An isosceles triangle is one that has two sides that are the same length and two angles that are the same size.

In an isosceles right triangle, the length of the hypotenuse is equal to the product of the square root of 2 and the length of either leg. So, we have:

√(72) = s x √(2)

Simplifying this, we get:

s = √(72) / √(2)

Rationalizing the denominator, we get:

s = √(72/2)

s = √(36)

s = 6

Therefore, the length of the other leg of the isosceles triangle is 6.
