i) u + 3 V
1 by 2 + 3 *minus 2
1 by 2 -6
1 - 12 by 2
- 11 by 2
ii) - 3 * 1 by 2 + 2 * -2 + 3 by 4
minus 19 by 4
Answer:
<h2> a. 392.7 yd³</h2><h2 />
Step-by-step explanation:
volume = 1/3 π r² h
where h = 15 yd.
r = 5 yd.
<u>plugin values into the equation:</u>
volume = 1/3 π r² h
= 1/3 * π * 5² * 15
= 392.7 yd³
Answer: 3/2
Step-by-step explanation:
We can cross multiply.
4x = 6.
Divide both sides by 4.
x = 6/4 which simplifies to 3/2
Step-by-step explanation:
First no. is 12
Second no. is 8
Third no. of 25
Way 1 of grouping the numbers,
(12×8)×25
We can use associative law of multiplication as follows :
(a×b)×c = a×(b×c)
(12×8)×25 = (96) × 25
= 2400
Way 2,
12×(8×25) = 12 × 200
= 2400
Way 2 is easier to simplify because when we multiply 8 and 25, we get 200. It is very easy to multiply any number with a number that have zeroes. As a result we easily get the answer i.e. 2400.
