Area of circle=Pi times radius^2
Diameter is half of radius=8.4
Pi*8.4^2=221.670777637
Hope this helps!
Answer:
221.56 cm^2 or 70.56pi
Step-by-step explanation:
Area of a circle = pi*radius^2
Radius = diameter/2, radius = 8.4
3.14(8.4)^2 = 221.56 cm squared, or 70.56pi
A mouse is traveling at a rate of 100 feet per hour. One half hour later, a snake smells the
mouse and follows the path of the mouse at a rate of 200 feet per hour. In how many hours
will the snake catch up to the mouse?
Let, snake catches the mouse in t hours. Till then mouse is travelling from
( t + 1.5 ) hours.
Distance, travelled by mouse in t hours is, [tex]d = 100(t+ 1.5)[/tex] .
To catch the mouse snake had to travel the same distance d in t hours.
So,
[tex]200t = 100( t + 1.5 )\\\\2t = t + 1.5\\\\t = 1.5 \ hours[/tex]
Therefore, snake will catch mouse in 1.5 hours.

Car A travels 90 km in the same time car B going 10 km/hr slower travels 60 km. Find the speech of each. List answer for car A first then car B. Do not show units.
Answer:
For
Car A : 30
Car B : 20
Step-by-step explanation:
Let the speed at which Car A travels be x and the time of travel be T. Recall that
speed = distance/time
Hence for Car A.
x = 90/T
T = 90/x
since Car B is B going 10 km/hr slower travels 60 km then
T = 60/(x - 10)
equating both equations
90/x = 60/(x - 10)
cross multiply
90(x - 10) = 60x
90x - 900 = 60x
90x - 60x = 900
30x = 900
Divide both sides by 30
x = 900/30
= 30
This is the speed of Car A : 30km/hr
The speed of Car B = 30 - 10 = 20 km/hr

Given the equations y = 4x + 5 and y = 4x - 7, what is the relationship
of the two lines?
O
A. Perpendicular
B. Parallel
C. Skew
D. Neither
Answer:
Parallel
Step-by-step explanation:
Given
[tex]y = 4x + 5[/tex]
[tex]y = 4x - 7[/tex]
Required
Determine the relationship
Both lines are parallel. This is so, because they have the same slope.
The equation of a line is:
[tex]y = mx + b[/tex]
Where
[tex]m = slope[/tex]
For [tex]y = 4x + 5[/tex]
[tex]m_1= 4[/tex]
For [tex]y = 4x - 7[/tex]
[tex]m_2 = 4[/tex]
By comparison:
[tex]m_1 = m_2 = 4[/tex]
Since both slopes are the same, then the lines are parallel

Answer:
y = -3x + 6
Step-by-step explanation:
We can first find the y intercept by looking at y when x = 0
y intercept = 6
We can then find the slope by looking at the patterns on the tables.
As we can see, the top row's pattern is +4 every time
The bottom row's pattern is -12
Slope = rise/run
-12/4 = -3
Therefore, the equation for the chart is y = -3x + 6

Answer:
simple, it's (4,4) because the (-4,-4) is on the left side then on the right side, we know the x axis is positive right? so then you know that the bottom of the y axis is negative and the x axis is first in the coordinate and so the first one is positive now.

The lottery prize is 2m on the 1st week, 5m on the 2nd week. 10m on the 3rd. 13m on
the 4th. 26m on the 5th and 29m on the 6th week.
a) How much is the prize in the 10th week?
b) How much more is the prize worth on the 14th week than the 11th week?
Answer:
a. $125 million
b. $259 million more
Step-by-step explanation:
Looking at the first 3 terms, 5 is 3 more than 2, and 10 is double 5. Knowing that, the pattern is every even term is 3 more than the previous odd, and every odd term is double the previous even. As a result, week 7's prize is $58m (29 * 2), week 8's is $61m (58 + 3), week 9 is $122m (61 * 2), and week 10 (what part a is asking for) is $125m (122 + 3).
Now for part 2. Week 11's prize would be $250m (125 * 2). Week 12's prize would be $253m (250 + 3). Week 13's would be $506 (253 * 2). Week's 14 would be $509 (506 + 3). Now, subtract 250 from 509 to find the difference in prize money, which is $259 million.

f(c)
Answer:
Selling Price = Cost + $3.00

The merchant uses Selling Price = Cost + $3.00 to determine the selling price.
What is Addition?Addition is a process of combining two or more numbers.
A merchant adds $3.00 to his cost to determine his selling price.
The cost is denoted by c.
The selling price is given by f(c).
As there is given add in the sentence, it means we have to use the addition rule.
Selling price is the sum of cost plus three
Selling Price = Cost + $3.00
So the table becomes as below
c 1, 2, 3, 4, 5,
f(c) 4, 5, 6, 7, 8,
Hence, the merchant uses Selling Price = Cost + $3.00 to determine the selling price.
