Answer:
Step-by-step explanation:
y= mx+ b helps you find the equations of the lines
y= x+2 is the line with slope m=1, and y-intercept b=2
y= -4x-3 is the line with slope m=-4, and y-intercept b=-3
y > x+2 because is a dotted line
y ≤ -4x-3 because is a solid line

f
is inversely proportional to
√
g
.
When
f
=
12
,
g
=
36
Work out
g
when
f
=
8
Answer:
g = 81.
Step-by-step explanation:
f = k/√g where k is a constant
When f = 12 g = 36, so:
12 = k/√36 = k/6
k = 12*6 = 72.
So the relation is:
f = 72/√g
When f = 8:
8 = 72/√g
8√g = 72
√g = 72/8 = 9
g = 9^2 = 81.

Find the area of a circle with the radius of 73 feet
Answer:
Step-by-step explanation:
area of a circle=πr^2
=3.14*(73)^2
=3.14*5329
=16733.06 ft^2
Answer:
A = 5329 pi ft^2
If we approximate pi with 3.14
A = 3.14*5329=16733.06 ft^2
If we use the pi button
A =16741.54725 ft^2
Step-by-step explanation:
The area of a circle is given by
A = pi r^2
The radius is 73
A = pi ( 73) ^2
A = 5329 pi ft^2
If we approximate pi with 3.14
A = 3.14*5329=16733.06 ft^2
If we use the pi button
A =16741.54725 ft^2
Which expression is equivalent to (3x + 4)(2x - 3)?
Answer:
Step-by-step explanation:
If there are choices, you should list them. It's a guess about which is correct. I'll list 2 of them.
(3x + 4)(2x - 3) can be
(2x - 3)(3x + 4) or
F: 3x*2x = 6x^2
O:3x * -3 = - 9x
I : 4 * 2x = 8x
L: 4 * - 3 = - 12
When added, you get
6x^2 -9x + 8x - 12
6x^2 - x - 12
A rectangular tank measures 13 cm by 8 cm by 10 cm. How many milliliters of water are in the tank when it is full? How many liters?
Answer:
10400MM
1.04 litre
Step-by-step explanation:
volume = length x width x height
13 x 8 x 10 = 1040 cm^3
1cm = 10 mm
1040 x 10 = 10400MM
1cm = 0.001 litres
1040 x 0.001 = 1.04 l

Jimmy and Jennifer are selling pies for a school fundraiser. Customers can buy apple pies and blackberry pies. Jimmy sold 10
apple pies and 2 blackberry pies for a total of $80. Jennifer sold 10 apple pies and 3 blackberry pies for a total of $100. Find the
cost each of one apple pie and one blackberry pie.
Answer:
One apple pie is $4 and one blackberry pie is $20
Step-by-step explanation:
Create a system of equations where a is the cost of one apple pie and b is the cost of one blackberry pie:
10a + 2b = 80
10a + 3b = 100
Solve by elimination by multiplying the top equation by -1, then adding the equations together:
-10a - 2b = -80
10a + 3b = 100
Add these together:
b = 20
So, one blackberry pie is $20. Plug in 20 as b into one of the equations, and solve for a:
10a + 2b = 80
10a + 2(20) = 80
10a + 40 = 80
10a = 40
a = 4
So, one apple pie is $4.
One apple pie is $4 and one blackberry pie is $20

The probability for event A is 0.4, the probability for event B is 0.2, and the probability of events A and B is 0.1.
Why are the events not independent?
The sum of P(A) and P(B) is greater than P(A and B).
The product of P(A) and P(B) is greater than P(A and B).
The product of P(A) and P(B) is not equal to P(A and B).
The sum of P(A) and P(B) is not equal to P(A and B)
Answer:
the correct answer is the product of PA) and P(B) is not equal to P(A and B)
