Find the probability of “landing” in the shaded region of the figures below.
9514 1404 393
Answer:
3/16
Step-by-step explanation:
The radii of the three circles appear to be in the ratios ...
5 : 10 : 20 = 1 : 2 : 4
Then the areas of the circles will be in the ratios that are the square of these:
1 : 4 : 16
The shaded area is the area of the middle-sized circle, less the area of the smaller circle, so is 4-1 = 3 "ratio units". The ratio of that area to the area of the largest circle is the probability of randomly choosing a point in the shaded area:
p(shaded) = 3/16
Answer:
3/16

A point is dilated by a scale factor of 1/3 centered about the origin, resulting in the
new coordinates (-6,3). What are the coordinates of the point prior to the
dilation?
Answer:
(-18, 9)
Step-by-step explanation:
If a coordinate A(x,y) is dilated by a factor of k, the new coordinates will be expressed as;
A' = (kx, ky)
A' = A (kx, ky)
Given the following
k = 1/3
A' = (-6, 3)
Substitute
(-6, 3) = 1/3(x, y)
Cross multiply
3(-6, 3) = (x, y)
(x, y) = (3(-6), 3(3))
(x, y) = (-18, 9)
Hence the coordinate prior to dilation is (-18, 9)

Usually Jim walks at a speed of 5 miles/h and Jerry walks at a speed of 6 miles/h. If Jerry walked for 3 hours to climb a hill, how long will Jim take to climb the same hill?
Answer:
1.80 hours or 1 hour and 48 minutes
Step-by-step explanation:
Jerry = 3 miles every hour
Jerry took 3 hours to climb the hill.
It is safe to say that he traveled 3 miles every hour for 3 hours so he traveled 3 x 3 = 9 miles in all.
Jim walks at a speed of 5 miles an hour.
Question : How many hours would it take to travel 9 miles
9/5 = 1 4/5 of an hour
1 4/5 of an hour 1 hour 48 minutes

What expression defines Sn?
Answer:
Sₙ=3(1/2^n)
Step-by-step explanation:
Notice that in the given series that each term is being multiplied by 1/2, which is our common ratio. 3/2 is the first term because 3*1/2=3/2, so the expression that defines Sₙ is Sₙ=3(1/2^n)

2 2/7 + 4 1/2 simplified
Answer:
2 2/7 + 4 1/2
Step-by-step explanation:
Exact form 95/14 for me
Mixed number will be 6 11/14
2 2/7 + 4 1/2 simplified fraction is 95/14.
To simplify the expression 2 2/7 + 4 1/2, we can convert the mixed numbers to improper fractions and then add them together.
Converting the mixed numbers to improper fractions:
2 2/7 can be written as (2 x 7 + 2)/7 = 16/7
4 1/2 can be written as (4 x 2 + 1)/2 = 9/2
Now we can add the fractions together:
16/7 + 9/2
To add fractions, we need to have a common denominator. In this case, the least common denominator (LCD) of 7 and 2 is 14.
Converting both fractions to have a denominator of 14:
16/7 x 2/2 = 32/14
9/2 x 7/7 = 63/14
Now we can add the fractions:
32/14 + 63/14 = (32 + 63)/14 = 95/14
Therefore, 2 2/7 + 4 1/2 simplified is 95/14.

If you were to solve the following system using substitution, your new equation would be...
Answer:
2x+ (x-1) = 8
Simplified
3x-1 =8
Step-by-step explanation:
y=x−1
2x+y=8
Take the first equation and everywhere you see y in the second equation substitute x-1
2x+ (x-1) = 8
You can simplify
2x+x-1 =8
3x-1 =8
If you want to solve
3x-1+1 =8+1
3x= 9
Divide by 3
3x/3 =9/3
x=1
Then solve for y
y = x-1
y = 3-1
y=2
