Answer:

6F

Step-by-step explanation:

Let x be the temperature at noon

dropping means we subtract

The temperature at 9 pm was -4.  That goes on the right hand side of the equals

x-10 = -4

Add 10 to each side

x-10+10 = -4+10

x = 6

The temperature at noon was 6 F

What is the perimeter of the woods, in miles? Round<br> you<br> answer to the nearest tenth.
Stells [14]

The perimeter of the woods is 26 miles if each grid represents one mile in the figure.

<h3>What is the area of the rectangle?</h3>

It is defined as the space occupied by the rectangle which is planner 2-dimensional geometry.

The formula for finding the area of a rectangle is given by:

Area of rectangle = length × width

We know the perimeter of the rectangle = 2(length + width)

As we can see closely in the figure the perimeter of the wood is actually a perimeter of a rectangle if we shift vertical and horizontal lines to make it a complete rectangle.

Let's suppose each grid is expressing one mile.

So the length of the rectangle = 9 miles

The width of the rectangle = 4 miles

The perimeter of the woods  = 2(9+4) = 26 miles

Thus, the perimeter of the woods is 26 miles if each grid represents one mile in the figure.

One year ago, a man was 8 times as old as his son. Now his age is equal to the square of his sons age. The present age of son is
Svetlanka [38]

Answer:

The present age of son is 7

Step-by-step explanation:

Let the son age be x

One year ago

Son's age = x - 1

Therefore man's age = 8(x-1) =8x - 8

Now man's age = x^2

Difference between both ages if man =1 years

So

x^2 -(8x-8) = 1

x^2-8x + 8-1 =0

x^2- 8x + 7 = 0

x^2 - 7x -x + 7 = 0

X(x-7) - 7 ( x - 7) = 0

(x - 1) ( x - 7) = 0

x = 1, 7

But son cannot be 1 years

Therefore ,

x = 7

SO,

age of son is <em>7</em>

age of father is x×7=<em>49</em>
