Ok, if you decrease <span>£2500 by 1% you get 99% remaining
</span>So
99% of £2500 = 0.99 x £2500 = <span>£2475</span>
2) 2/7 divided 1/3 = 6/7
3) 4/9 times 3/8 = 1/6
4) 5/8 times 2/15 = 1/12
5) 1 divided 3/4 = 1 1/3
6) 1/8 times 8 =1/64
7) 2 1/4 times 1/6 = 3/8
8) 5/8 times 2 2/3 = 1 2/3
9) 1 1/8 times 4 = 4 1/2
10) 2 1/5 divided 11 = 1/5
11) 4 1/2 times 1 1/3 =6
12) 2 1/7 divided 3 3/7
13) 2 2/9 times 7 = 16
Answer:
Step-by-step explanation:
hello
a) Pop as this is the one with the most CDs
b) 30 as this is a full one 20 + half 10 = 30
c) POP 5*20= 100
Jazz 2*20=40
Classical 1.5*20=30
Rock 3*20=60
so the total is 100+40+30+60 = 230
hope this helps
X = 8
y = 4
You can get this by graphing each equation and looking for the point of intersection.
Answer:
Option: a is correct
a) y= -cos x
Step-by-step explanation:
We could clearly see that the graph of the function passes through a point on the y-axis which is :
(0,-1)
i.e. when x=0 the value of the function y= -1
So we will check in each of the following options by putting x=0 and check whether y= -1 or not.
b)
y=sin x
on putting x=0 we get:
y=sin 0=0≠ -1.
Hence, option b is incorrect.
c)
y= cos x.
we put x=0
y= cos 0=1≠ -1.
Hence, option c) is incorrect.
d)
y= -sin x
we put x=0 to obtain:
y= -sin 0=0≠ -1.
Hence, option d is incorrect.
Hence we are left with option a i.e.
The graph represents the function:
y= -cos x. (Hence, option a is correct)
( Also it satisfies at x=0
since, y= -cos 0= -1 )
