Answer:
11.5
Step-by-step explanation:
r= SI×100
_______
P×T
= 9200×100
_________
20000×4
= 920000
________
80000
Answer:
T-6=X
Step-by-step explanation:
Tracey = T
X = Awnser
If we are subtracting six from Tracey's age, you would subtract six from T
since we don't know Tracey's age, it is represented by T.

Answer:
<em>The shaded region has an area of 1400 square units</em>
Step-by-step explanation:
<u>Area of Compound Shapes</u>
We are given a shape and it's required to calculate its area. The shape can be divided into three rectangles as shown in the figure attached below.
The lengths of these rectangles are x, y, and z.
The value of x can be calculated as:
x = 60 - 15 - 10 = 35
Similarly:
y = 60 - 15 = 45
z = y = 45
The first rectangle has dimensions of x by 10, thus its area is:
A1 = 35*10 = 350
The second rectangle has dimensions of 60 by 10:
A2 = 60*10 = 600
The third rectangle has dimensions y by 10:
A3 = 55*10 = 450
The shaded area is:
A = 350 + 600 + 450 = 1400
The shaded region has an area of 1400 square units

Answer:A)0.27
B)0.78
Step-by-step explanation:
This is the probability of picking 2balls of same color.
P(RR)+Pr(WW)+Pr(BB)
3/10×2/9+4/10× 3/10+3/10 ×2/9=6/90+12/90+6/90=
24/90=4/15=0.27
B)if the first ball is not returned, then there are 9 balls left.
Then probability of same color will be
PrB+PrW+PrR
2/9+3/9+2/9=
7/9=0.78
