Basically use the formula y1-y2 over x1-x2 and just plug in the number
Answer:
11 pencils cost £9.35.
Step-by-step explanation:
Given;
7 pencils = £5.95
1 pencil = 5.95 ÷ 7
= £0.85
Now,
11 pencils = 11 × 0.85
= £9.35
Answer:
120√6
Step-by-step explanation:
Simplify the 5√8 to 2√2
simplify the √18 to 3√2
so it would be √3 * 2√2 * 5 * 2√2 * 3√2
when a square root of an expression is multiplied by itself:
√3 * 2 * 2* 5 * 2 * <em>3</em>√2
so as we calculate it, 2 * 2* 5 * 2 * <em>3</em> = 120 and √2 * √3 = 6
I Agree because everything has to come with lines because every thing has to come in a shape with lines
So, the area of a circle is a=pi r^2
so do that and get a=pi(4)
and since the circle touches the edge of the rectangle, the rectangle is 4 cm tall, so 4*8 is 32 and pi(4) is about 12.56, so 32-12.56 is 19.44, and I believe that is the answer. (19.4)
