8 and 9, since square root of 64 is 8 and square root of 81 is 9, it is known that square root of 75 is between 8 and 9
0.2÷ 1 then × both by 100 to change it to 20/100 then simplify by ÷5 which equals 4/20.
31. 4/20 to 1/5
0.24 × 100= 24
1×100 = 100
simplify 24 ÷ 4= 6 then 100÷4= 25
34. 6/25
-0.1 ×100= -10
1×100=. 100
simplify -10÷2=-5 then 100÷ 2= 50
32. -5/50 to -1/10
Just do that for 33, 35 and 36
X^2 + kx + 15 = 0
3^2 + 3k + 15 = 0
9 + 3k + 15 = 0
24 + 3k = 0
3k = -24
k = -24/ 3
k = -8
Answer: 65
Step-by-step explanation: 15 goes into 975 65 times. You do 975/15 and get 65. To prove its right, you can do 65 times 15 and it equals 975, so its right! Hope this helped
Answer:
10.35
Step-by-step explanation:
So we solve by cross multiplication
11 pounds---------------113.85
1 pound. --------------- ?
so ?= (113.85*1) / 11
so ?=10.35
