Answer:
81
Step-by-step explanation:
4 : 9
36 : ?
to get from 4 to 36, you multiply 9
9 x 9 = 81
Step-by-step explanation:
Firstly, notice that this shape is composed of ³/₄ of a circle and ¹/₂ of a square;
The lower left part is the ¹/₂ square, with only 2 sides (a left and lower side) of length 3 units;
The perimeter of this part of the shape is simply the sum of the two sides:
3 + 3 = 6
The remaining part is the ³/₄ circle, which has a radius of 3 units;
The circumference of a circle is found by the formula:
πd
d = diameter = 2 × radius
We only have ³/₄ of the circle, however, so we only have ³/₄ the circumference:
³/₄ × π(2(3)) = ³/₄ × 6π
= ⁹/₂π (or, equally, 4.5π)
So the total perimeter is the sum of the perimeter of the ¹/₂ square and the ³/₄ circle:
4.5π + 6
Answer:
x = 1
Step-by-step explanation:
1. Expand.
6x − 18 + 10 = 8x − 10
2. Simplify 6x − 18 + 10 to 6x − 8.
6x − 8 = 8x − 10
3. Subtract 6x from both sides.
−8 = 8x − 10 − 6x
4. Simplify 8x − 10 − 6x to 2x − 10.
−8 = 2x − 10
5. Add 10 to both sides.
−8 + 10 = 2x
6. Simplify −8 + 10 to 2.
2 = 2x
7. Divide both sides by 2.
1 = x
8. Switch sides.
x = 1
<em>There are 201 10's in 2010. Find how many tens are in 2000 (multiply 10 by 200) and then add 10 for the 10 in 2010. There are 201 tens.</em>
