Remark
Interesting question. Thanks for posting.
The small triangle has the height as the missing side.
Part One: Givens
a = 144
b = height = ?
c = 240
a^2 + b^2 = c^2
144^2 + b^2 = 240^2
20736 + b^2 = 57600 Subtract 20736 from both sides
b^2 = 57600 - 20736
b^2 = 36864
√b^2 = √36864
b = 192
Solve for x
The relationship between the height (b) and 144 and x is
b^2 = 144 * x
36864 = 144x Divide by 144
x = 256
Suppose log8(3)=a and log8(5)=b. What is log 8(45) in terms of a and b?
====================================================
Work Shown:
[tex]\log_8(3) = a\\\\\log_8(5) = b\\\\\log_8(45) = \log_8(3*3*5)\\\\\log_8(45) = \log_8(3)+\log_8(3)+\log_8(5)\\\\\log_8(45) = a+a+b\\\\\log_8(45) = 2a+b\\\\[/tex]
The log rule used was log(x*y) = log(x)+log(y).

A copy machine can print 340 color copies every 8 minutes. So how many copies can be made 28 minutes
Answer:
1190
Step-by-step explanation:
We have the ratio: 8:340 which means that 340 copies are printed in 8 minutes
We want to find out how many color copies are printed in 1 minute so we divide by 8
so our new ratio is now 1:42.5
We now multiply this ratio by 28 to find out how many are printed in 28 minutes
28:1190
our answer is 1190 copies

Step-by-step explanation:
Terry is purchasing a bike that is on sale for 40% off the original price. After a coupon is applied that reduces the sale price by 20%, Terry's final cost for the bike is $168. What was the original price of the bike Terry is purchasing?
Answer: $350
Step-by-step explanation:
Terry bought the bike at $168 after using a coupon that reduced the price by 20%.
The sales price was therefore:
= 168/ (1 - 20%)
= $210
The sales price which is $210, was gotten after a 40% discount was applied on the original price.
Assume that original price was x:
x - (x * 40%) = 210
x - 0.4x = 210
0.6x = 210
x = 210/0.6
= $350

Stacey earns $15 each week plus $.50 for each customer on her paper route. She
wants to earn at least $25 each week. What equation can she use to find x, the
number of customers she needs to make exactly $25?
Answer:
15 + .50x ≥ 25 (20 customers)
Step-by-step explanation:
to get a minimum of $25 per week, Stacey needs to earn $10 on her paper route since she is already getting $15 per week in general. Now we can divide 10 by .50 to find out how many customers Stacey needs to make $25 per week. 10/.50 is 20 which means that Stacey needs at least 20 customers to make at least $25 per week.
(sorry if this is confusing but I hope it helped)
The equation can be used to find the number of customers is -
25 = 15 + 0.5x
The equation can be used to find the number of customers.
We have Stacey who earns $15 each week plus $ 0.50 for each customer on her paper route. She wants to earn at least $25 each week.
We have to determine which equation can she use to find x, the number of customers she needs to make exactly $25.
Write a equation to represent the count of bacteria (y) after x days such that at x = 0, the bacteria count is 10000 and then increases by 2000 per day.The equation representing the above situation is -
y = 10000 + 2000x = 2000(5 + x)
According to the question, we have -
Money earned by Stacey each week = $ 15
Additional money she earns for each customer = $0.50
Money Stacey wants to earn per week = $25
Net additional money she need = $25 - $15 = $10
Now, she earns -
$0.50 → 1 customer
$1 → [tex]$\frac{1}{0.50}[/tex] customers
$10 → [tex]$\frac{1}{0.50} \times 10[/tex] = 2 x 10 = 20 Customers.
In the form of equation, assume that she needs 'x' customers to make exactly $25.
Therefore -
25 = 15 + 0.5x
The above equation can be used to find the number of customers.

Answer: x = 11.5
Step-by-step explanation: Since the line bisects angle BAC, this means angles BAD and DAC equal each other.
To find what angle DAC equals, you divide 75 by 2, which equals 37.5
Then you set 37.5 equal to (3x+3) and solve for x.
37.5 = 3x+3
34.5 = 3x
11.5 = x
F(x)=-x^3+24x^2-179x+495 determine the
Average rate of change of f(x) between x=2 and x=5
Answer:
The average rate of change is -75
Step-by-step explanation:
The Average Rate of Change (ARC)
It's a measure of how much the function changed per unit, over a given interval.
Given a function F(x) and an interval between x=a and x=b, the average rate of change is:
[tex]\displaystyle A=\frac{F(b)-F(a)}{b-a}[/tex]
The function is:
[tex]F(x)=-x^3+24x^2-179x+495[/tex]
and it's required to find the ARC between x=2 and x=5.
Calculate F(2) and F(5):
[tex]F(2)=-2^3+24*2^2-179*2+495=225[/tex]
[tex]F(5)=-5^3+24*5^2-179*5+495=75[/tex]
The ARC is:
[tex]\displaystyle A=\frac{75-225}{5-3}=\frac{-150}{2}=-75[/tex]
The average rate of change is -75
Two correspoding sides of similar triangles are 2 and 5. What is the area of the second triangle if the area of the first one is 8
Answer:
The area would be 80
Step-by-step explanation:
Firstly we need the scale factor
At 2 to 5, the scale factor is 5/2 = 1 to 2.5
Mathematically, we have the area of a triangle as:
1/2 * b * h
So, if the other side is x ;
we have that :
1/2 * x * 2 = 8
2x = 16
x = 8
The bigger other side will be;
2.5 * 8 = 20
So the area of the second will be;
1/2 * 20 * 8 = 80

The parallelogram shown represents a map of the boundaries of a natural preserve. Walking trails run from points A to C and from points B to D. The measurements shown represent miles. Parallelogram A B C D is shown. Diagonals are drawn from point A to point C and from point D to point B and intersect at point E. The length of D E is y + 2, the length of E B is 3 y minus 4, and the length of E C is 2 y minus 3. What is the sum of the lengths of the two trails? 6 miles 12 miles 16 miles 36 miles
Answer:
[tex]16\ \text{miles}[/tex]
Step-by-step explanation:
In a parallelogram the diagnols bisect each other. So,
[tex]DE=EB\\\Rightarrow y+2=3y-4\\\Rightarrow 4+2=3y-y\\\Rightarrow 6=2y\\\Rightarrow y=\dfrac{6}{2}\\\Rightarrow y=3[/tex]
[tex]DE=y+2\\\Rightarrow DE=3+2\\\Rightarrow DE=5[/tex]
[tex]BD=2DE\\\Rightarrow BD=2\times 5\\\Rightarrow BD=10[/tex]
[tex]EC=2y-3\\\Rightarrow EC=2\times 3-3\\\Rightarrow EC=3[/tex]
[tex]AC=2EC\\\Rightarrow AC=2\times 3\\\Rightarrow AC=6[/tex]
The sum of the diagonals is [tex]BD+AC=10+6=16\ \text{miles}[/tex]
The sum of the lengths of the two trails is [tex]16\ \text{miles}[/tex].
Answer:
16 Miles

A particular airport has beacons on the ground 6 km out from the start of each runway. An airplane is directly over this beacon and is at an angle of elevation from the runway of 8°. Calculate the direct line distance from the airplane to the start of the runway
Answer:
6.06 km
Step-by-step explanation:
The information given in the question can be represented by the three sides if a right angled triangle.
Let the direct line from the airplane to the start of the runway be represented by x. So that applying the appropriate trigonometric function, we have;
Cos θ = [tex]\frac{adjacent}{hypotenuse}[/tex]
Cos [tex]8^{o}[/tex] = [tex]\frac{6}{x}[/tex]
0.9903 = [tex]\frac{6}{x}[/tex]
⇒ x = [tex]\frac{6}{0.9903}[/tex]
= 6.0588
x = 6.06 km
The direct line from the airplane to the stat of the runway is 6.06 km.

Solve the following system algebraically, for values a, b, and c.
2a + b + c = 17
1/2c = 5
a-b=5
Answer:
a= 4
b= -1
c= 10
Step-by-step explanation:
First we start by multiplying both sides of 1/2c = 5 by 2.
c = 10
Add b to both sides of the last equation to make it a=b+5
knowing these two things, we can plug them into the first equation like this:
2(b+5) + b + 10 = 17
then you solve for b:
distribute the 2
2b + 10 + b + 10 = 17
combine like terms
3b + 20 = 17
subtract 20 from each side
3b = -3
divide by 3
b = -1
then you can plug that into the last equation again so a - (-1) =5
Subtracting a negative is the same as adding so its a + 1 = 5 or a = 4
