Answer:

71.1 vreels on the farm

Step-by-step explanation:

Create a proportion where x is how many vreels are on the farm:

[tex]\frac{9}{8}[/tex] = [tex]\frac{80}{x}[/tex]

Cross multiply and solve for x:

9x = 640

x = 71.1

So, to the nearest tenth, there are 71.1 vreels on the farm.

Step-by-step explanation:

1. m = (9-3)/(2-1) = 6/1 = 6 => B

2. m = (-7-5)/(2+1) = -12/3 = -4 => G

3. the horizontal line passes (0,4) => m = 0 =>I

4. m = (2-1)/(8-8) = 1/0 = oo => undefined => A

Answer:

x1=-4,y1=-1,x2=2,y2=3

Now,

slope (m)=3/2

By formula,

(y-y1)=m (X-x1)

y-(-1)=3/2(x+4)

y+1=3/2(x+4)

2y+2=3x+12

3x-2y+10=0,which is required equation.

Answer:

44m²

Step-by-step explanation:

Area of larger rectangle

= length × breadth

= 8m × 4m

= 32m²

Area of smaller rectangle

= length × breadth

= 4m × 3m

= 12m²

Total area of the figure

= Area of larger rectangle + Area of smaller rectangle

= 32m² + 12m²

= 44m²

Answer:

y=-3/11x+67/11

Step-by-step explanation:

y-8=-5-8/4--7(x--7)

y-8=-3/11(x+7)

11y-88=-3x-21

11y=-3x-21+88

11y=-3x+67

y=-3/11x+67/11

Answer:

y = -13/11x - 3/11

Step-by-step explanation:

First, find the slope of the line using the slope formula.

[tex]m=\frac{y_2-y_1}{x_2-x_1}\\m=\frac{-5-8}{4-(-7)}\\m=-\frac{13}{11}[/tex]

Then, use the point-slope formula and substitute the values for the variables.

[tex]y-y_1=m(x-x_1)\\y-8=-\frac{13}{11}(x-(-7))\\y-8=-\frac{13}{11}x-\frac{91}{11}\\y=-\frac{13}{11}x-\frac{3}{11}[/tex]

Using the converse of the Pythagorean's theorem, the triangle is right.

Using Pythagorean theorem, the points 3 + i, 6, and 4 + 4i indeed form the vertices of a right triangle.

The Pythagorean theorem states that in a right triangle, the sum of the squares of the lengths of the two shorter sides (legs) is equal to the square of the length of the longest side (hypotenuse).

Let's calculate the distances between the points and then check if the Pythagorean theorem holds for them.

Distance between points A (3 + i) and B (6):

Distance AB = |6 - (3 + i)|

                     = |6 - 3 - i|

                     = |3 - i|

                     = [tex]\sqrt{(3^2 + (-1)^2)[/tex]

                     = √10

Distance between points A (3 + i) and C (4 + 4i):

Distance AC = |4 + 4i - (3 + i)|

                     = |1 + 3i|

                     = [tex]\sqrt{(1^2 + 3^2)[/tex]

                     = √10

Distance between points B (6) and C (4 + 4i):

Distance BC = |4 + 4i - 6|

                     = |-2 + 4i|

                     = [tex]\sqrt{((-2)^2 + 4^2)[/tex]

                     = √20

Now let's check if the Pythagorean theorem holds for these distances:

Longest side: [tex]BC^2 = (\sqrt20)^2 = 20[/tex]

Sum of squares of shorter sides:

[tex]AB^2 + AC^2 = (\sqrt10)^2 + (\sqrt10)^2[/tex] = 10 + 10 = 20

Since the sum of the squares of the shorter sides is equal to the square of the longest side.

So, the points 3 + i, 6, and 4 + 4i are vertices of a right triangle.

Answer:

P) = 1/2 jawbreaker

simplified P) 3/6 = 1/2 jawbreaker

Which both mean the same, so show simplified if asked and either answer if not asked would be marked high.

as 2/6 + 1/3 = 3/6

1 - 3/6 = 3/6

= 1/2    are the workings.

Step-by-step explanation:

Jelly bean = 1/3 = 2/6

Gumdrop = 1/6

2/6 + 1/6 = 3/6 = the difference of 1

1-3/6 = 3/6

Therefore; P) = 3/6 jawbreaker

Answer:

Step-by-step explanation:

Answer:

10

Step-by-step explanation:

|5-9|+2*3

lets use the P.E.M.D.A.S order of operations rule

we have no parenthesis or exponents, so we skip to multiplication

2*3=6

then we do addition/subtraction

since the subtraction sign comes first in the equation, we evaluate

5-9=-4

since the subtraction part is in the absolution value signs, we change -4 to its absolute value.

|-4|=4

now we are left with 4+6

add

4+6=10

so, |5-9|+2*3=10

the answer would be

A. 53-53i !! :)

it was also the correct answer on the test ,, goodluck !!

Answer = B. -17 -53i
