Answer:

Step-by-step explanation:
From the diagram provided, we have the following information;
Parallelogram CDEF
[tex]Base=29[/tex]
[tex]Height=21[/tex]
Triangle EBF
[tex]Base=11[/tex]
[tex]Height=21[/tex]
We would begin by calculating the area of both plane shapes;
The area of the parallelogram is given by the formula;
[tex]Area=b*h[/tex]
[tex]Area=29*21[/tex]
[tex]Area=[/tex][tex]609cm^{2}[/tex]
The area of the triangle is given by the formula;
[tex]Area=[/tex][tex]\frac{1}{2}b*h\\[/tex]
[tex]Area=[/tex][tex]\frac{1}{2}*11*21[/tex]
[tex]Area=[/tex][tex]\frac{231}{2}[/tex]
[tex]Area= 115.5[/tex][tex]cm^{2}[/tex]
To find out how much greater is the area of the parallelogram (CDEF) than that of the triangle (EBF) in square centimeters, we simply find the difference between both results and this now gives us;
[tex]Parallelogram-Triangle=609-115.5[/tex]
[tex]Parallelogram-Triangle=493.5[/tex]

The opening balance of one of the 31-day billing cycles for Suzy's credit card
was $7400, but after 15 days Suzy made a payment of $4900 to decrease her
balance, and it stayed the same for the remainder of the billing cycle. if her
credit card's APR is 22%, how much more in interest would she pay for the
billing cycle with the previous balance method than with the adjusted balance
method?
Answer: $91.56
Step-by-step explanation: honestly im just winging it hope its right
The amount she will pay more in interest when she pays for the
billing cycle with the previous balance method than with the adjusted balance method is $47.26.
What is simple interest?It is the interest calculated on the principal at a given rate for a time period.
The formula for simple interest is PRT/100.
Where P is the principal, R is the rate, and T is the time in years.
We have,
Previous balance method:
P = 7400
T = 31 days
R = 22%
SI:
= (7400 x 22 x 31) / (100 x 365)
= 50468 / 365
= $138.27 ________(A)
Adjusted balance method.
P = 7400
T = 15 days
R = 22%
SI
= (7400 x 22 x 15) / (100 x 365)
= $66.90 _____(1)
After 25 days,
P = 7400 - 4900 = 2500
T = 16 days
Si:
= (2500 x 22 x 16) / (100 x 365)
= $24.11 ______(2)
From (1) and (2),
SI = 66.90 + 24.11 = $91.01 _______(B)
Now,
From (A) and (B) we get,
138.27 - 91.01
= 47.26
Thus,
$47.26 more interest is paid.

a) make a R subject of this formula
b) find the number of hours of overtime worked by someone whose total wage is $8200
Step-by-step explanation:
a)
W = 200R + 5900
now, we want to transform this, so we get R = ...
W - 5900 = 200R
R = (W - 5900)/200

Christy and Emily both have circular pools in their backyard. The surface area of Christy’s pool is 16 times greater than that of Emily’s pool.
How much greater is the diameter of the larger pool?
4 times
16 times
32 times
8 times
The diameter of Christy's pool is 4 times larger than the other .-.
How to find the relation between the radius of each pool?
We know that for a circle of radius R the area is given by:
A = π*R^2
Let's say that:
R is the radius of Christy's poolR' is the radius of Emily's pool.Then we have the corresponding areas.
A = π*R^2A' = π*R'^2We know that:
A = 16*A'
Replacing the equations, we get:
π*R^2 = 16*(π*R'^2)
R^2 = 16*R'^2
If we apply the square root in both sides, we get:
√R^2 = √(16*R'^2)
R = 4*R'
This means that the radius of Christy's pool is 4 times larger than the one of Emily's pool.
And the same is for the diameter (twice the radius).
D = 2*R
D' = 2*R'
Then:
D = 2*R = 2*(4*R') = 4*(2*R') = 4*D'
The diameter of Christy's pool is 4 times larger than the other diameter.

Dwayne drove 18 miles to the airport to pick up his father and then returned home. On the return trip he was able to drive an average of 15 miles per hour faster than he did on the trip there. If the total driving time was 1 hour, then what was his average speed driving to the airport?
Someone please help
Answer:
30 mph
Step-by-step explanation:
Let d = distance (in miles)
Let t = time (in hours)
Let v = average speed driving to the airport (in mph)
⇒ v + 15 = average speed driving from the airport (in mph)
Using: distance = speed x time
[tex]\implies t=\dfrac{d}{v}[/tex]
Create two equations for the journey to and from the airport, given that the distance one way is 18 miles:
[tex]\implies t=\dfrac{18}{v} \ \ \textsf{and} \ \ t=\dfrac{18}{v+15}[/tex]
We are told that the total driving time is 1 hour, so the sum of these expressions equals 1 hour:
[tex]\implies \dfrac{18}{v} +\dfrac{18}{v+15}=1[/tex]
Now all we have to do is solve the equation for v:
[tex]\implies \dfrac{18(v+15)}{v(v+15)} +\dfrac{18v}{v(v+15)}=1[/tex]
[tex]\implies \dfrac{18(v+15)+18v}{v(v+15)}=1[/tex]
[tex]\implies 18(v+15)+18v=v(v+15)[/tex]
[tex]\implies 18v+270+18v=v^2+15v[/tex]
[tex]\implies v^2-21v-270=0[/tex]
[tex]\implies (v-30)(v+9)=0[/tex]
[tex]\implies v=30, v=-9[/tex]
As v is positive, v = 30 only
So the average speed driving to the airport was 30 mph
(and the average speed driving from the airport was 45 mph)
Let s represent the speed on the return trip
So, The initial speed will be (s-15)
Equation of time:
[tex] \boxed{ \tt \: time = \frac{distance}{speed} }[/tex]
return time + initial time = 1 hr

Answer:
[tex]\frac{x+3}{x}[/tex] or x+3/x
Step-by-step explanation:
Using D.O.T.S (difference of two squares) formula :
[tex]a^{2} -b^{2} = (a+b)(a-b)[/tex]
[tex]x^{2} -9= (x+3)(x-3)[/tex]
Factorise the second bit:
[tex]x^{2} -3x = x(x-3)[/tex]
Now write out this fraction:
[tex]\frac{(x+3)(x-3)}{x(x-3)}[/tex]
Now we can cancel out repeated terms (x-3):
[tex]\frac{(x+3)}{x}[/tex]
This is our final answer:

Answer:
[tex]x^{2} -3x-\frac{9}{x^{2} }[/tex]
Step-by-step explanation:

To add or subtract expressions, expand them to make their denominators the same. Multiply [tex]x^{2} -3x[/tex] times [tex]\frac{x^{2} }{x^{2} }[/tex]
-
[tex]\frac{(x^{2} -3x)x^{2} }{x^{2} } - \frac{9}{x^{2} }[/tex]
Since [tex]\frac{(x^{2} -3x)x^{2} }{x^{2} }[/tex] and [tex]\frac{9}{x^{2} }[/tex] have the same denominator, subtract them by subtracting their numerators.
-
[tex]\frac{(x^{2} -3x)x^{2} -9}{x^{2} }[/tex]
Do the multiplications in [tex](x^{2} -3x)x^{2} -9[/tex]

[tex]\frac{x^{4}-3x^{3}-9 }{x^{2} }[/tex]

Answer:
x = 2
Step-by-step explanation:
when you set these two equations equal to each other, you plug in numbers for x until you find one that makes both sides of the equation equal. For example, 2^x - 1 = -x + 5 if you plug a 2 in for x you get 4-1 = -2+5 and both sides of the equation are equal to 3
