   Looking at the figure, the rectangle has the vertexes (2,1), (3,-3), (-5,-5) and (-6,-1). The parallelogram has the vertexes (2,7), (3,3), (3,-3), and (2,1).

The area of a parallelogram is base times height. We have 2 vertical lines at x=2 and x=3, so the height is 1. And the length of the line from (3,3) to (3,-3) is 6, so the base is 6. Therefore the area of the parallelogram is 1*6 = 6.

  The rectangle is a tad trickier since it's not aligned with either the x or y axis. But we can use the Pythagorean theorem to get the lengths.

 L = sqrt((2 - -6)^2 + (1 - -1)^2)

 L = sqrt(8^2 + 2^2)

 L = sqrt(64 + 4)

 L = sqrt(68) = 2*sqrt(17)

  W = sqrt((2-3)^2 + (1- -3)^2)

 W = sqrt((-1)^2 + 4^2)

 W = sqrt(1 + 16)

 W = sqrt(17)

  And the area is length * width, so:

 2*sqrt(17)*sqrt(17) = 2 * 17 = 34

  And the total area is the sum of the areas, so

 34 + 6 = 40

  So the area of the figure is 40 square units.

Answer:

The value of n = 12

Step-by-step explanation:

Given the points

  • (-4, n)
  • (2, 4n)

The slope formula

m = y₂-y₁ / x₂ - x₁

\left(x_1,\:y_1\right)=\left(-4,\:n\right),\:\left(x_2,\:y_2\right)=\left(2,\:4n\right)    

m=\frac{4n-n}{2-\left(-4\right)}

m=\frac{n}{2}

Given that the slope = m = 6

Thus, substituting the value

6 = n/2

n = 6 × 2

  = 12

Thus, the value of n = 12

On a map, the distance from Happy Hill Park to Rainbow Valley Park is 4/1/2 inches. The scale is 1/2 inch: 3 miles. What is the
Studentka2010 [4]

we are given

The scale is

\frac{1}{2} inch=3miles

the distance from Happy Hill Park to Rainbow Valley Park is 4 1/2 inches

we can change it into rational form

and we get

=\frac{9}{2}inch

so, we can multiply both sides by 9

9*\frac{1}{2} inch=9*3miles

now, we can simplify it

\frac{9}{2} inch=27 miles

so, the actual distance between the two parks is 27 miles........Answer

An event has a probability of 1/2. How would you best describe the likelihood of this event? (Hint: Change it to a decimal)
noname [10]

Answer:

Equally Likely

Step-by-step explanation:


The answer is equally likely because equally likely events have the same probability of happening as another event.

For example, a fair coin.

It has a 1/2 chance of beng tails, and 1/2 chance of being heads, meaning that both tails and heads are Equally Likely to land.

Hope this helps!

Summer day camp is about to begin. Today there are 132 boys signed up and 219 total children signed up. How many more than girls
Aleks04 [339]
To find the number of girls signed up for camp, we just subtract the number of boys from to total number of children. There are 132 boys and 219 children, which gives us

219 - 132 = 87 girls. To find how many boys there are than girls, we just find the difference between the 132 boys and 87 girls by subtracting again:

132 - 87 = 45 more girls than boys.
