Answer:
There are total 55 counters out of which 11 are green and 44 are other color.
Step-by-step explanation:
This is a ratio and proportion question. There are c amount of counters in the box .
The chosen have the same ratio as in the box
Green : total
4: 20
11: x
Using cross product rule
x * 4= 20 *11
x= 20*11/4
x= 55
So there are total 55 counters out of which 11 are green and 44 are other color.
Benedict take 20 counters out of which 4 are green.
Answer:
x+1+2x-6= 16
3x-5 =16
3x=16+5
3x=21
x=21/3
x= 7
VW= 2x-6 = 2(7) -6 = 14-6 = 8
Answer : 4
Explanation : the second triangle is dilated by 2 .
Answer:
1
Step-by-step explanation:
Tangent of [5 pi]/4
The expression above is given in radian; when ever you have something like this- take note, it's in radian.
Pi [in radian] = 180 in degrees
Hence [5 pi]/4 = [5 x 180]/ 4 =5 x 45 = 225
So Tan 225 = Tan [225-180] =Tan 45
and Tan 45 =1
16- let x represent the number:
x+ (x+1)+(x+2)=100
collect like terms
3x+3=100
3x=97
x=~32 but we need an odd number so round to 31, since 33 would be too great
31+33+35=99
therefore, the three numbers are 31, 33, 35
