Answer:
2640mm
Step-by-step explanation:
I'm assuming you need the area of the rectangle which the circles don't take up.
First, to find the area of the whole rectangle:
length x width
to find length:
the length is 1 circle, therefore it is the diameter of the circle, which is 32 x 2 = 64mm
to find width:
the width is 3 circles, which is the radius 6 times, so 32 x 6 = 192mm
So, area of rectangle = 64 x 192 = 12288mm
Now to find the area the circles take up:
area of 1 circle =
=
=
As we have 3 circles, we multiply this by 3:
Finally we subtract the area of the three circles from the area of the rectangle:
As we need to round it to 3 significant figures, the answer is 2640mm
There are 3 x intercepts
(-2, 0) (0, 0) and (2, 0)
There is a y intercept at (0, 0)
Symmetric about x axis: No
Symmetric about y axis: No
Symmetric about the origin: Yes
Answer: 280
Step-by-step explanation:
(-11 - 17) (2 - 12) = 280/1 = 280
Subtract: -11 - 17 = -28
Subtract: 2 - 12 = -10
Multiple: the result of step No. 1 * the result of step No. 2 = -28 * (-10) = 280
Answer:
16
Step-by-step explanation:
The equation is 3/4x=12, so you would just divide 12 by 3/4 to get 16 as x
<h3>Linear expression represents the missing length</h3>
<em><u>Solution:</u></em>
The perimeter of the triangle shown is represented by the expression 10x - 1
The lengths of two sides are given: 3x + 1 and 5x - 2
We have to find the length of third side
We know that,
perimeter of the triangle = sum of length of all three sides
10x - 1 = 3x + 1 + 5x - 2 + third side
10x - 1 = 8x - 1 + third side
third side = 10x - 1 - 8x + 1
third side =2x
2x has variable x and its power is 1
Linear expression is an algebraic expression where the power of variable is equals to 1
Thus linear expression represents the missing length
