A new one year membership at Fit and fab costs $577. A registration fee of $25 is paid up front, and the rest
paid monthly. Write the equation
How much do new members pay each month?
Answers
Answer:
[tex]y = 25 + 46x[/tex] --- Equation
$46 monthly
Step-by-step explanation:
Given
[tex]Registration = \$25[/tex]
[tex]Total = \$577[/tex]
Solving (a): The equation
Out of $577, $25 is paid as registration fee
So, the members are left with $552 (i.e. $577 - $25) to pay over 12 months
Let the number of months be x and the total amount to pay be y.
The equation is:
[tex]y = Registration + Monthly * x[/tex]
[tex]y = 25 + \frac{552}{12}*x[/tex]
[tex]y = 25 + 46*x[/tex]
[tex]y = 25 + 46x[/tex]
Solving (b): The monthly payment
In (a) above, we established that:
"So, the members are left with $552 (i.e. $577 - $25) to pay over 12 months"
The monthly payment is:
[tex]Monthly = \frac{552}{12}[/tex]
[tex]Monthly = \$46[/tex]

Sarah is dividing pies into eighths. She has 4 pies. How
many eighths will she have?
Answers
Answer:
32 eighths
Step-by-step explanation:
If each pie is being divided into 8 parts then all you have to do is multiply 8 by the number of pies (4). 8 * 4 = 32
The number of eighths Sarah will have is 8.
Given to us,
Total number of pies Sarah have = 4,
Each pie is divided into eighths, therefore, in 8 parts.
The number of eighths Sarah will have = number of pies Sarah x 8 parts.
= 4 x 8 parts
= 32 eighths
Hence, the number of eighths Sarah will have is 8.

what is the distance covered if a car travels 2.5 miles at a speed of 40mph
solutions please
Answers
Answer:
100 miles
Step-by-step explanation:
I think you means 2.5 hours, not 2.5 miles.
speed = distance/time
Multiply both sides by time.
speed * time = distance
distance = speed * time
You are given: 2.5 hours, 40 miles/hour
distance = 40 miles/hour * 2.5 hours
distance = 100 miles

and GE = 50 feet. Find the length of EF to the nearest tenth
of a foot.
Answers
Answer:
73.3
Step-by-step explanation:
Using the SOH CAH TOA identity
EF = hypotenuse= x
FG = opposite
GE = adjacent = 50feet
Cos 47 = adj/hyp
Cos 47 = 50/x
x = 50/cos47
x = 50/0.6819
x = 73.32

(-1,-4). What is the area of
the circle?
How do you solve? What formula do you use?
Answers
Answer:
The area of the circle is around 50.24
Step-by-step explanation:
The formula for the area of a circle is [tex]\pi r^{2}[/tex]
To find r, we can use the point that is given to us. To find the distance of the radius, we can use the formula
[tex]d=\sqrt{(x2-x1)^{2}+(y2-y1)^{2} }[/tex]
We can just plug in the points given into the formula and we get,
4.
Now we can plug 4 into the formula
[tex]\pi r^{2}[/tex]
[tex](3.14)(4^{2})[/tex]
Resulting in,
around 50.24.

Complete the Area Model that would be used to multiply
4x(x² + 2x +3)
Answers
Answer:
16x^3 + 8x^2 + 12x
Step-by-step explanation:
Given the product 4x(x^2+2x+3)
On Expanding
4x(x^2+2x+3)
= 4x(x^2)+4x(2x)+4x(3)
= 16x^3 + 8x^2 + 12x
Hence the Area of the model is 16x^3 + 8x^2 + 12x
The area model is as follows:
4x × (x²) = 4x³
4x × (2x) = 8x²
4x × (3) = 12x
The area model that will be use to multiply 4x(x² + 2x +3) is as follows:
4x(x² + 2x +3)4x × (x²) = 4x³
4x × (2x) = 8x²
4x × (3) = 12x
Therefore,
4x(x² + 2x +3) = 4x³ + 8x² + 12x

Given that Laura has 78 apple trees in her cider farm, with a mean of 460 apples per tree, but then she has had to get a tree cut down, and after that, the mean of apples per tree became 462, to determine how many apples were there on the tree that Laura had to cut down, the following calculation must be performed:
(78 x 460) - (77 x 462) = X
35.880 - 35.574 = X
306 = X
Thus, the tree that Laura had to cut had 306 apples.
