The solutions to the questions are
- The number we are using is 5
- The perfect square number closest to the area is 1024
- The estimated side length is 32
<h3>What are areas?</h3>
The area of a shape is the amount of space on the shape
For most regular quadrilaterals, you multiply the side lengths to determine the area
<h3>The number to use</h3>
The area expression is given as
Area = ▢ × 102 + ▢ × 101 + 6
From the question, we can use any number
However, this number must be positive
Assume the number is 5
So, we have
Area = 5 × 102 + 5 × 101 + 6
<h3>The perfect square number closest to the result</h3>
In (a), we have:
Area = 5 × 102 + 5 × 101 + 6
Evaluate
Area = 1021
The perfect square number closest to this is
Closest = 1024
<h3>The estimated side length</h3>
In (b), we have
Closest = 1024
Rewrite as
Area = 1024
Take the square roots
Length = 32

#SPJ1
The answer is the third option
C=2πr
We have 3/4 of circumference
(3π/2)*2π=3/4.
and it is equal 5π/2.
(3/4)*C=(3/4)*2πr
5π/2 = 6πr/4
5/2=6r/4
r=(5/2)*(4/6)=(5*4)/(2*6)=5/3
r=5/3
Answer:
w= -9/8
Step-by-step explanation:
-1/3w -3/5 = 1/5w
+1/3w +1/3 w
-3/5=1/5w+1/3w
Make common denominators to combine like terms of the right
-3/5=1/5w+1/3w
*3 *5
-3/5=3/15w+5/15w
-3/5=8/15w
multiply both sides by the reciprocal of 8/15 which is 15/8
-3/5*15/8=8/15w*15/8
*
----> cross reduce 5 in the denominator becomes 1 and 15 in the numerator becomes 3
*
-----> now multiply across
w= -9/8
