Answer:

A = h²

Step-by-step explanation:

the area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )

here b = 2h , then

A = [tex]\frac{1}{2}[/tex] × 2h × h = h × h = h²

Answer:

a = 3

Step-by-step explanation:

Calculate the distance d using the distance formula and equate to 4

d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = (2, - 1) and (x₂, y₂ ) = (2, a)

d = [tex]\sqrt{(2-2)^2+(a+1)^2}[/tex] = [tex]\sqrt{0+(a+1)^2}[/tex] = [tex]\sqrt{(a+1)^2}[/tex] = a + 1 then

a + 1 = 4 ( subtract 1 from both sides )

a = 3

Answer:

For me when I am finding the slope I actually use the slope formula [tex]\frac{y2-y1}{x2-x1}[/tex].

Step-by-step explanation:

Step 1 you have to find the x and y

Step 2: Use the slope formula

Step 3: Subtract y2 and y1 to get your answer

Step 4: Subtract x2 and x1 to get your answer

Step 4: If your answer is easy to divide  simplify it, if not leave it as it is

That's all I know

I hope this helps :)

Answer:

Choose two sets of data (x and y values).  Calculate the difference between the two y values.  Calculate the difference between the corresponding two x values.  Slope is the difference in y values / difference in x values.

Step-by-step explanation: it went 40 feet to get to the surface of the water then it went and extra 10 feet above water so 40+10=50

The pound that he ad will be 19/30 pounds.

From the information, it was stated that Sean bought 4/5 of a pound of cherries and then he ate 1/3 of a pound of them.

He also found out that he had 1/6 of a pound of cherries in his cupboard.

Therefore, the total will be:

= (4/5 - 1/3) + 1/6

= 24/30 - 10/30 + 5/30

= 19/30

Therefore, the pound that he ad will be 19/30 pounds.

Answer:

Finding the y value is easy if you know the slope of the line and the x coordinate. Review the equation for the slope of a line. The equation for finding the slope is: m = [y1 - y2] / [x1 - x2]. If you know x, you can solve for y to find the y value for the slope of the line.

Answer:

A. 94.37 seconds

B. 0.48 seconds

Step-by-step explanation:

Total distance = 50 meters

First trial = 32.15 seconds

Second trial = 31.67 seconds

Third trial = 30.55 seconds

A. What is Todd's combined time for all three trials

Todd's combined time for the three trials = First trial + Second trial + Third trial

= 32.15 seconds + 31.67 seconds + 30.55 seconds

= 94.37 seconds

B. How much faster was Todd's second trial than his first trial?

Second trial = 31.67 seconds

First trial = 32.15 seconds

Time taken for first trial - Time taken for second trial -

= 32.15 seconds - 31.67 seconds

= 0.48 seconds

Todd's second trial was 0.48 seconds faster than his first trial

5x - 40 = 20

5x = 20 + 40

5x = 60

x = 60/5

x = 12

Answer:

x = 12

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Equality Properties

Step-by-step explanation:

Step 1: Define equation

5(x - 8) = 20

Step 2: Solve for x

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Here we see that 20 does indeed equal 20.

∴ x = 12 is a solution to the equation.

Step-by-step explanation:

Step 1: Define Equation

-4(x + 2) = 4(2 - 2x)

Step 2: Solve for x

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Here we see that -24 does equal -24.

∴ x = 4 is the solution to the equation.

Answer:

The coordinates of the midpoint of the line segment p(-5,-1) Q(6,-2) would be: (1/2, -3/2)

Step-by-step explanation:

Given

[tex]\mathrm{Midpoint\:of\:}\left(x_1,\:y_1\right),\:\left(x_2,\:y_2\right):\quad \left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)[/tex]

[tex]\left(x_1,\:y_1\right)=\left(-5,\:-1\right),\:\left(x_2,\:y_2\right)=\left(6,\:-2\right)[/tex]

[tex]=\left(\frac{6-5}{2},\:\frac{-2-1}{2}\right)[/tex]

[tex]=\left(\frac{1}{2},\:-\frac{3}{2}\right)[/tex]

Thus, the coordinates of the midpoint of the line segment p(-5,-1) Q(6,-2) would be: (1/2, -3/2)

You just know when u got it

Answer:

Is 18.6 feet

Step-by-step explanation:

There are 544,320 7-digit numbers that are all unique and arranged in increasing order.

We apply the Fundamental Counting Principle to this issue. You are aware that a number has seven digits. According to this theory, you must multiply the potential integers for each digit. There are 9 potential numbers if the initial number can't be zero. Consequently, the first digit's value is 9. Any number, but less than 1, could be used for the second digit since it was already used in the first. Thus, 10 – 1 would equal 9. The value in the third digit must be less than 1 and in the second digit. In this case, 9 – 1 Equals 8. And the list goes on.

Therefore, the number of seven-digit numbers in which all digits are different and in increasing order is:

9 × 9 × 8 × 7 × 6 × 5 × 4 = 544,320

Hence, there are 544,320 7-digit numbers with all different digits in increasing order.

Answer:

Step-by-step explanation:

Alexis is X years old

Josiah is X + 5 years old

in 7 years:

Alexis is x + 7 years old

Josiah is x + 5 + 7 => x + 12 years old

Sum of their ages is 85 :

x + 7 + x + 12 = 85

2x + 19 = 85

2x = 85 - 19 = 66

x = 66/2 = 33 => Alexis age

Josiah is x + 5 = 33 + 5 = 38 years old

Abbie takes 110 minutes t  complete painting work alone.

Let x= time takes Abbie to paint the room

1 minute =1/x part the of room painted paint by Abbie paint the room

2x  minute times takes both to paint the room

so, in 1 minute 1/2x part of the  room  paint by Abbie and Beth

Abbie paints three times  faster than  Cathie

Cathie takes 3x minutes take time to paint the room.

in 1 minute 1/3x part of room  paint by Cathie

they take 60 minute  to paint a room all three working together

in 1minute 1/x+ 1/2x+ 1/3x parts

in 60 minute = ( 1/x+1/2x+ 1/3x) 60 =1 room

                     = [tex]\frac{6x+3x+2x}{6x^{2} } 60[/tex] = 1

                     =   [tex]\frac{11x}{6x^{2} } 60[/tex] = 1

Answer:

we would add [tex]\:\left(\frac{1}{2}\right)^2\:[/tex] or 1/4 to make the expression a perfect square.

Step-by-step explanation:

Given the expression

[tex]x^2+x[/tex]

[tex]\mathrm{Write}\:x^2+x\:\mathrm{in\:the\:form:\:\:}x^2+2ax+a^2[/tex]

[tex]2a=1[/tex]

Divide both sides by 2

[tex]\frac{2a}{2}=\frac{1}{2}[/tex]

[tex]a=\frac{1}{2}[/tex]

as

[tex]x^2+2ax+a^2=\left(x+a\right)^2[/tex]

[tex]\mathrm{Add\:}\:\left(\frac{1}{2}\right)^2\:[/tex]

[tex]x^2+1x+\left(\frac{1}{2}\right)^2=\left(x+\frac{1}{2}\right)^2[/tex]
