The sides show that we have an equilateral triangle
What is the measure of each of the sides?An equilateral triangle is a triangle in which all three sides are of equal length. Since all three sides are equal, all three angles are also equal and measure 60 degrees each.
We know that;
12x - 22 = 10x - 6
Collect like terms;
12x - 10x = -6 + 22
2x = 16
x = 8
Thus the sides of the triangle are;
12(8) - 22 = 74
10(8) - 6 = 74
7(8) + 18 = 74
In the second triangle;
4x - 25 = x + 14
4x - x= 14 + 25
3x = 39
x = 13
Thus the sides are;
4(13) - 25 = 27
13 + 14 = 27
6(13) - 51 = 27

Based on the information, bIda would owe $3700 at the end of 12 months.
Ida would owe $3808 at the end of 12 months.
How to calculate the interestThe formula will be:
I = P * r * t
I = 2500 * 0.04 * 12 = $1200
So, Ida would owe $2500 + $1200 = $3700 at the end of 12 months.
b. For option b, , the monthly interest rate is:
r = 0.01 * 4.33 = 0.0433
Using the same simple interest expression:

I am unsure about how to do this problem, pictured below.
Answer:
Step-by-step explanation:
150/2 = 75
500/75 = 6.6666666667 hours
it will take 6.2/3 hours to reach 500 bacteria cells
NOT SURE ABOUT EXPERSION BUT YOU COULD TRY THIS
p = 75t
Given that a culture of bacteria grows at a rate proportional to its size. Where the culture starts with 50 cells, then grows 150 after time, "t" equals 2 hours.
We are asked to:
> (a) Find an expression, P(t), to model the number of cells present after "t" hours.
> (b) Determine the time at which the population is at 500 cells.
For part (a):
Since the culture of bacteria grows at a rate proportional to its size, we can model it as the following differential equation.
[tex]\Rightarrow \frac{dP}{dt}=kP; \ Where \ P =P_0 \ at \ t=0 \ and \ P=3P_0 \ at \ t=2[/tex]
Solve the first-order separable differential equation with the given initial condition.
[tex]\Longrightarrow \frac{dP}{dt}=kP \Longrightarrow \frac{1}{P}dP=kdt \Longrightarrow \int\limits {\frac{1}{P} } \, dP=\int\ {k} \, dt \Longrightarrow ln(P)=kt+c[/tex]
[tex]\Longrightarrow e^{ln(P)}=e^{kt}+e^{c} \Longrightarrow P=ce^{kt}[/tex]
Plug in the initial condition.
[tex]\Longrightarrow P_0=ce^{k(0)} \Longrightarrow P_0=c(1) \Longrightarrow \boxed{c=P_0}[/tex]
[tex]\Longrightarrow P=ce^{kt} \Longrightarrow \boxed{P=P_0e^{kt}}[/tex]
Use the second initial condition to find "k."
[tex]\Longrightarrow 3P_0=P_0e^{k(2)} \Longrightarrow 3=e^{k(2)} \Longrightarrow 3=e^{2k} \Longrightarrow ln(3)=ln(e^{2k})[/tex]
[tex]\Longrightarrow k=\frac{ln(3)}{2} \Longrightarrow \boxed{k \approx 0.5493}[/tex]
Thus, the equation to model the situation is,
[tex]\boxed{\boxed{P(t)=50e^{0.5493t}}} \therefore Sol.[/tex]
For part (b):
[tex]P=10P_0[/tex]
[tex]\Rightarrow 10P_0=P_0e^{0.5493t} \Longrightarrow 10=e^{0.5493t} \Longrightarrow ln(10)=ln(e^{0.5493t})[/tex]
[tex]\Longrightarrow ln(10)=0.5493t \Longrightarrow t=\frac{ln(10)}{0.5493} \Longrightarrow \boxed{t=4.192 \ hrs}[/tex]
Thus, the time it takes the population to reach 500 is approx. 4.192 hours.

7. Not congruent
8. Congruent by the HL theorem
HL = hypotenuse leg
==========================================
Explanation for problem 7
The tickmarks on segments MA and AT tell us that these segments are congruent. Another pair of congruent segments would be AE = AE by the reflexive property.
Then angle EMA = angle ETA because of the similar arc markings for those angles.
We have these congruence facts:
MA = AT (side)AE = AE (side)angle EMA = angle ETA (angle)But recall that the "side side angle" rule isn't a valid congruence theorem. Search out "SSA ambiguous case" for more information.
We cannot use SAS because the angle is not between the sides mentioned.
Therefore, we don't have enough information to determine if the triangles are congruent or not. We can't say they are congruent, so the only thing we can do is say "not congruent" until more info comes along.
------------
Explanation for problem 8
We use the HL (hypotenuse leg) theorem. It works for right triangles only.
The congruent legs are segment ON = segment ON because of the reflexive property.
The congruent hypotenuses are MN = RO because of the tickmarks.
In short, the triangles are congruent by the HL theorem.
Which function represents the graph of f(x) = -4 lxl after it is translated 3 units down?
A.g(x) = -4 lxl + 3
B. g(x) = -4 lxl - 3
C. g(x) = -4 lx + 3|
D. g(x) = -4 lx - 3l
Answer:
B
Step-by-step explanation:
When translating in the y-axis, we want to add or subtract our value outside of the function, or in this case, outside of the modulus.
We want to move 3 units down, or 3 units in the negative direction. Therefore, we take 3 away from the function.

Rewrite the following in the form log(c). log(5) + log(2)
Answer:
log(10)
Step-by-step explanation:
We can use the product property for logarithms:
log(a)+log(b)=log(ab)
In our case, a=5 and b=2. We can multiply a and b now to get the new number we're taking the logarithm of.
log(2)+log(5)=log(2×5)=log(10)
Given X = [b a / 4 a] , Y = [c d / a b] , and Z= [a c / 16 b]
What is Y if X-2Y=Z?
[2 -4/ -6 -2]
[4 -8/ -12 -4]
[-4 8/ 12 4]
[12 0/ 12 -12]
Answer:
[2 -4/ -6 -2]
Step-by-step explanation:
To solve for Y, we need to rearrange the equation X-2Y=Z to isolate Y.
X - 2Y = Z
2Y = X - Z
Y = (X - Z)/2
Now we substitute the given matrices for X and Z, and solve for Y:
X =
[b a
4 a]
Z =
[a c
16 b]
X - Z =
[b-a a-c
-12 a-b]
Y = (X - Z)/2 =
[(b-a)/2 (a-c)/2
-6 (a-b)/2]
So the answer is Y = [ (b-a)/2, (a-c)/2 / -6, (a-b)/2 ].
Therefore, the answer is (a) [2 -4/ -6 -2].
The calculated value of the matrix Y is [tex]Y = \left[\begin{array}{cc}2&-4\\-2&-6&\end{array}\right][/tex]
Calculating the matrix YFrom the question, we have the following parameters that can be used in our computation:
The matrix definitions
Given that
X - 2Y = Z
So, we have
b - 2c = a
a - 2d = c
4 - 2a = 16
a - 2b = b
So, we have
4 - 2a = 16
-2a = 12
a = -6
Next, we have
a - 2b = b
-6 - 2b = b
3b = -6
b = -2
Next, we have
b - 2c = a
-2 - 2c = -6
-2c = -4
c = 2
Lastly. we have
a - 2d = c
-6 - 2d = 2
-2d = 8
d = -4
The matrix Y is given as
[tex]Y = \left[\begin{array}{cc}c&d\\b&a&\end{array}\right][/tex]
So, we have

How to determine the time when the object would reach a height of 96 feet?Based on the information provided, we can logically deduce that the height (h) in feet, of this object above the ground is related to time by the following quadratic function:
h(t) = h₀ - 16t²
When the initial height is 208 feet and final height is 96 feet, the height function becomes;
h(t) = h₀ - 16t²
96 = 208 - 16t²
16t² = 208 - 96

In a jar of lollies there are 6 more orange lollies than green ones and there is only one red lolly. If there are 47 lollies in the jar, how many orange ones are there?
Answer:
Let's use "g" to represent the number of green lollies in the jar.
According to the problem, there are 6 more orange lollies than green ones, so the number of orange lollies is "g + 6".
We also know that there is only one red lolly.
The total number of lollies in the jar is 47, so:
g + (g + 6) + 1 = 47
Simplifying the equation:
2g + 7 = 47
Subtracting 7 from both sides:
2g = 40
Dividing by 2:
g = 20
So there are 20 green lollies in the jar.
And since there are 6 more orange lollies than green ones, there must be:
g + 6 = 20 + 6 = 26 orange lollies in the jar.

A wallet contains 34 notes, all of which are either $5 or $10 notes. If it amounts to $235, how many $10 notes are there?
Answer:
For this question, you can use the simultaneous equation to solve this problem.
Equation 1 reads: x + y = 34. (There are 34 notes in total.)
Equation 2: 5x + 10y = 235 (The notes are worth a total of $235.)
To find x in terms of y, we can apply equation 1:
x = 34 - y
When we use this expression to replace x in equation 2, we obtain:
5(34 - y) + 10y = 235
By condensing and figuring out y, we get at:
y = 15
There are 15 $10 bills in the wallet as a result.
An airplane company flies 39 airplanes daily. The CEO collects the following passenger counts for a random sample of airplanes from the fleet, as shown below. 123, 132, 158, 77, 158, 123, 132, 123, 158, 77 Assuming that the sample is representative of the entire fleet of airplanes, what would be the mean daily passenger count per plane?
Answer:
To find the mean daily passenger count per plane, we need to calculate the average of the passenger counts for the sample.
We can do this by adding up all the passenger counts and dividing by the number of planes in the sample:
(123 + 132 + 158 + 77 + 158 + 123 + 132 + 123 + 158 + 77) / 10
= 1259 / 10
