hello
to determine if the sequence is arthimetic or a geometric progression, we check if a common difference or common ratio exists between the two sequence
the sequence is 36, 30, 24, 18,......
from careful observation, this is an arthimetic progression because a common difference exists between them
d = 30 - 36 = -6
or
d = 24 - 30 = -6
to find the 67th term, let's apply the formula
[tex]\begin{gathered} T_n=a+(n-1)d \\ T_{67}=a+(67-1)d \\ a=\text{first term = 36} \\ d=common\text{ difference = }-6 \\ T_{67}=36+(67-1)\times-6 \\ T_{67}=36+66\times-6 \\ T_{67}=36-396 \\ T_{67}=-360 \end{gathered}[/tex]Beth Johnson's bank card account charges 1.1% every month on the average daily balance as well as the following special fees:Cash advance fee: 2% ( not less than $2 nor more than $10)Late payment fee: $25Over-the - credit- limit fee $10In the month of June, Beth's average daily balance was $1886.

A student sketched some art on an 8-inch x 10-inch piece of paper. She wants to resize it to fit a 4-inch x 6 inchframe (as shown below).What percent of the original sketch was still able to be included in the frame?
So,
The area of art can be found multiplying:
8in * 10in = 80in²
And, the area of the frame, can be also found multiplying the dimentions:
4in * 6in = 24in².
If we divide, we'll obtain a ratio between the area of the frame and the area of the art as follows:
[tex]\frac{24}{80}=0.3[/tex]And, 0.3*100% = 30%.
So,30 percent of the original sketch was still able to be included in the frame.
A car rental company’s standard charge includes an initial fee plus an additional fee for each mile driven. The standard charge S (in dollars) is given by the function S = 15.75+0.50 M, where M is the number of miles driven. The company also offers an option to ensure the car against damage. The insurance charge I in dollars is given by the function I = 5.70+0.15 M. Let C be the total cost in dollars for a rental that includes insurance. Write an equation relating C to M.
Answer:
[tex]C\text{ = 0.65 M + 21.45}[/tex]Explanation:
Here, we want to write an equation that relates C to M
From the given question, we have to add the insurance to the standard charge to get the total cost
Mathematically:
[tex]C\text{ = S + I}[/tex]Now, we substitute the values for both S and I
That would be:
[tex]\begin{gathered} C\text{ = 15.75 + 0.50M + 5.70 + 0.15 M} \\ C\text{ = 0.65M + 21.45} \end{gathered}[/tex]I need help with this kind of math please. I have tried doing it but I’m so lost and confused
GF < GE < EF
Explanation:The given angles:
∠G = 74°
∠F = 65°
∠G + ∠F + ∠E = 180° (sum of angles in a triangle)
74 + 65 + ∠E = 180
139 + ∠E = 180
∠E = 180 - 139
∠E = 41°
The size of the side length of the triangles corresponds the size of the angles.
The higher the angle, the higher the side length and viceversa
∠E corresponds to side GF
∠F corresponds to side GE
∠G corresponds to side EF
∠E = 41 is the lowest, followed by ∠F = 65, highest is ∠G = 74
From least to greatest:
GF < GE < EF

We have the function:
[tex]y=f(t)=(-18t-3)\cdot(t-2).[/tex]a. Zeros of the function
By definition, the zeros are the values of t such that f(t) = 0. In this case, we have:
[tex]f(t)=(-18t-3)\cdot(t-2)=0\text{.}[/tex]Rewriting the function, we have:
[tex]f(t)=(-18)\cdot(t+\frac{1}{6})\cdot(t-2)=0.[/tex]So the zeros of the function are:
[tex]\begin{gathered} t=-\frac{1}{6}, \\ t=2. \end{gathered}[/tex]b. Meaning of the zeros
The function y = f(t) represents the height of the ball at time t.
• So the zeros are the times at which the function reaches a height equal to zero.
,• We see that one zero is positive and the other negative. Only the positive zero (t = 2) is meaningful because the negative (t = -1/6) represents a negative value of time!
c. Initial height
The ball is thrown at time t = 0. The height of the ball at time t = 0 is:
[tex]y=f(0)=(-18\cdot0-3)\cdot(0-2)=(-3)\cdot(-2)=6.[/tex]So the ball is thrown from a height of 6 feet.
Answer
• a., The zeros are t = -1/6 and t = 2.
,• b., The zeros are the values of time at which the height of the ball is zero. Only a positive value of time makes sense, so only the zero t = 2 is meaningful.
,• c., The ball is thrown from a height of 6 feet.
How many solutions does the following equation have? - 6(x + 7) = - 4x – 2 А. No solutions B.Exactly one solution C.Infinitely many solutions
ANSWER
Exactly one solution.
EXPLANATION
We are given the equation:
-6(x + 7) = -4x - 2
To find the number of solutions, we have to solve for x:
-6x - 42 = -4x - 2
Collect like terms:
-6x + 4x = 42 - 2
-2x = 40
x = 40 / -2
x = -20
Therefore, the equation has exactly one solution.
Round 0.145 to the nearest hundredth
The hundredths are two places from the right of the decimal point, in this case, in the hundredth place we have a 4 (0.145). if the digit on the right of the hundredths is 5 or more, and the second digit (in the hundredth place) is less than 9, then we have to add 1 to it and remove the third digit. In this case, the third digit is 5 and the second digit is 4, then we have to remove the 5 and add 1 to the 4, then we get:
0.145 rounded to the nearest hundredth is 0.15

Answer: This would be the answer to your question!!
Step-by-step explanation:
What is the solution for the system given below 4x + 8y = 20 and -4x + 2y = -30
You have the folloiwng system of equations:
4x + 8y = 20
-4x + 2y = -30
In order to solve the previous system, proceed as follow:
Sum the equations and solve for y:
4x + 8y = 20
-4x + 2y = -30
10y = -10
Divide by 10 both sides
y = -10/10
y = -1
Now, replace the previous value of y into the any of the equations of the system, for instance, into the first equation and solve for x:
4x + 8y = 20
4x + 8(-1) = 20
4x - 8 = 20
add 8 boht sides, simlplify and divide by 4 both sides:
4x = 20 + 8
4x = 28
x = 28/4
x = 7
Hence, the solution of the given system of equations is given by:
x = 7
y = -1
x = -1,0,1,2,3.
P(X = x) 0.2, 0.2, 0.2, 0.2, 0.2. Find the value of P(X<3).
The value of the probability P(x < 3) is 0.8
How to determine the probability value?From the question, the table of values is given as
x = -1,0,1,2,3.
P(X = x) 0.2, 0.2, 0.2, 0.2, 0.2
To calculate the probability P(x < 3). we make use of the probability values where x is less than 3
This means that
P(x < 3) = P(-1) + P(0) + P(1) + P(2)
Substitute the known values in the above equation
So, we have
P(x < 3) = 0.2 + 0.2 + 0.2 + 0.2
Evaluate the sum
P(x < 3) = 0.8
Hence, the probability value is 0.8

a leaky faucet drips 5 teaspoons of water every 3 hours how long will it take the leaky faucet to drip 75 teaspoons of water
∵ 5 teaspoons of water dropped every 3 hours
∵ We need to find the time taken for 75 teaspoons
→ By using the ratio method
→ Time: teaspoons
→ 3 : 5
→ h : 75
→ By using cross multiplication
∵ 5 x h = 3 x 75
∴ 5h = 225
→ Divide both sides by 5 to find h
∴ h = 45

________ degrees
The angle subtend an arc length of 7 feet is 44.56°
Given,
Radius of a circle = 9 feet
Arc length of a circle = 7 feet
Arc length :
The distance between two places along a segment of a curve is known as the arc length.
Formula for arc length:
AL = 2πr (C/360)
Where,
r is the radius of the circle
C is the central angle in degrees
Now,
AL = 2πr (C/360)
7 = 2 × π × 9 (C/360)
7 = 18 π (C/360)
7/18π = C/360
C = (7 × 360) / (18 × π)
C = (7 × 20) / π
C = 140 / π
C = 44.56°
That is,
