Problem
Solution
We want to identify the percent of patients with type B blood and mail ?
For this case we can do the following operation:
p= success cases / total cases
The success cases on this case are 99 since represent the male with type B of blood and the total cases are just 714
p= 99/ 714 =0.139
And the answer for this case would be:
0.139
So remember that percent means parts out of 100 so
52%=52/100=0.52
26%=26/100=0.26
'of' means multily
0.52 times x=65
divide both sides by 00.52
x=125
26% of a number is 39
0.26 times y=39
divide both sides by 0.26
y=150
x=125
y=150
y is greater
you know that becuase we know that 52% is exatly twice of 26% so therefor, if x=y then 52% of x is half of 26% of y so to compare them, we just divide the 65 number by 2 to find 26% of that number to get 65/2=32.5
32.5<39 so x is smaller number
Tan 32 = f/18
f = 18 × tan 32
= 11.25
= 11 ( to 2 sf)
Hope it helped
answer is cpctc
corresponding parts of congruent triangles are congruent (cpctc)
7x + 6 < 3(x - 2)
7x + 6 < 3x - 6
7x - 3x < -6 - 6
4x < -12
x < -12/4
x < -3
<span>{x | x < -3}</span>
