6. A rectangle has a perimeter of 62 feet. If its length is 9 feet longer than its width, find
the dimensions of the rectangle.
62ft

Answers

Answer:

length = 20 ft, width = 11 ft

Step-by-step explanation:

let w be width, then length = w + 9

The opposite sides of a rectangle are equal , then

2w + 2(w + 9) = 62

2w + 2w + 18 = 62

4w + 18 = 62 ( subtract 18 from both sides )

4w = 44 ( divide both sides by 4 )

w = 11

and w + 9 = 11 + 9 = 20

then width = 11 ft and length = 20 ft

A scientist was in a submarine below sea level, studying ocean life. Over the next ten minutes, she went down 23.9 feet. How many feet had she been below sea level, if she was 82.2 feet below sea level after she went down?

Answers

Answer:

58.3

Explanation:

x is the depth that the scientist started at. The asked equation is

x + 23.9 = 82.2

To find x, all we have to do is reverse the equation by doing

82.2 - 23.9 = x

This gives us x = 58.3

~Simplify

-6x - 9 + 4x - 3 = 8

-2x - 12 = 8

~Add 12 to both sides

-2x = 20

~Divide -2 to both sides

x = -10

Answer:

  (x, y, z) = (2, 2, -1/2)

Step-by-step explanation:

Most manual solutions to a system of 3 equations in 3 unknowns are ad hoc. The idea is to take advantage of any relationships that might exist between the coefficients.

Multiply the first equation by 2, then subtract the third equation.

  2(2x -y -4z) -(x -2y) = 2(4) -(-2)

  4x -2y -8z -x +2y = 8 +2 . . . . . . . eliminate parentheses

  3x -8z = 10 . . . . . simplify

Now, we can subtract this from the second equation:

  (3x -2z) -(3x -8z) = (7) -(10)

  6z = -3 . . . . . . . simplify

  z = -1/2 . . . . . . . divide by 6

Using the second equation, we can find x:

  3x -2(-1/2) = 7

  3x = 6 . . . . . . . . subtract 1

  x = 2 . . . . . . . . . divide by 3

Using the last equation, we can find y:

  2 -2y = -2

  1 -y = -1 . . . . . . divide by 2

  y = 2 . . . . . . . . add y+1

The solution is ...

  (x, y, z) = (2, 2, -1/2)

Answers

Answer: Ray AC is correct

This is because ray AE points in the same direction along ray AC. Put another way, points C and E are on the same line as A. So relabeling from "ray AE" to "ray AC" does not change the ray itself.

Keep in mind that order is important. So saying "ray AE" is completely different from "ray EA" due to the fact that the first letter is the endpoint while the second letter is where the ray goes on forever. So we can think of starting at point A and going in the direction of E to get ray AE, or going in the direction of C to get ray AC, and we're talking about the same ray.

A net of a triangular prism is show. What is the surface area, in square feet, of the triangular prism?
44 square feet
96 square feet
108 square feet
120 square feet

Answers

Hello!

To find surface area, all you need to do is add up the areas of all the faces of the prism. Let’s start by remembering some basic area formulas:

Area of a triangle= 1/2*base*height
Area of a rectangle= length*width

First, find the area of each of the little triangles on the sides of the net. The base is 3 ft, and the height is 4 ft. So:

1/2*3*4= 6 ft

There are two triangles of the same size, so multiply that number by 2.

6*2=12

Now, find the area of the top rectangle:

3*8= 24

And the area of the bottom rectangle:

5*8= 40

Finally, add all of those numbers together:

12+24+40= 76 ft^2

That should be your answer!

What is the lowest altitude Ying will reach?

Answers

Answer:

The lowest point is -100 meters, or 100 meters down

Step-by-step explanation:

D(x)=1/36(x-60)^2-100

This equation is in vertex form

y = a(x-h)^2 +k  where (h,k) is the vertex

Since a is positive, the parabola opens up

The vertex is the minimum, which means it will be the lowest point

The vertex is (60,-100)

The lowest point is -100 meters, or 100 meters down

Given expression

y=1/36(x-60)²-100

Compare to the vertex form

y=a(x-h)²+k

We get

.

a=1/36(h,k)=vertex=(60,-100)

As a is positive parabola is opening upwards and vertex is minimum

Lowest altitude is -100m
