Since we know that one of the angles is 72° and the other two angles are the same..
We can subtract 72° from 180°
180°-72°=108°
Divide the result by 2
108°/2=54°
So the best answer would be B.54°
I hope this helps :)

C(The initial value is 32, and the rate of change is 1.
D(The initial value is 32, and the rate of change is 15.
Answers
Answer:
B) The initial value is 22, and the rate of change is 15.
Step-by-step explanation:
The first point is located at (22, 54). This means the initial value is 22.
The rate of change is found using the formula
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Using the first two points, we have
[tex]m=\frac{69-54}{37-22}\\\\=\frac{15}{15}=1[/tex]

Alana tosses 2 number cubes. She wins if she rolls double sixes. Find p(Alana wins)
Answers
The number of events we have in this situation is 2, one for each die. Each die has a 1/6 chance of landing a six, and we need two to win. So, the probability of this event is 1/6 times 1/6, or 1/36.
Alana has a 1/36 chance of winning by rolling two sixes.
Staci is attending a music festival. The ticket to the festival costs $87.96. Staci plans to purchase $30.00 t-shirt from the event for close friends. she is taking $200.00 to the festival. what is the maximum number of t-shirts can purchase?
Answers
After purchasing the festival ticket, Staci has $112.04 remaining from her $200 budget. Each T-shirt costs $30, so she can buy a maximum of 3 T-shirts.
Explanation:The student asked how many
T-shirts Staci can purchase at a music festival considering she has a budget of $200, and she also needs to buy a ticket and possibly T-shirts for her friends.
First, we need to subtract the cost of the festival ticket from Staci's total budget which is $200.00 - $87.96 = $112.04 remaining. Now, if each T-shirt costs $30.00, we can find the maximum number of T-shirts she can purchase by dividing the remaining money by the cost of one T-shirt.
$112.04 / $30.00 = 3.734.
Since Staci cannot buy a fraction of a T-shirt, she can purchase a maximum of 3 T-shirts with the remaining budget.
wich one is the solution???: 4(2x-1)=-3x+32
i dont understand this thing....
Answers
4 and 2x =8x 4 and -1 = -4
So, you know got:
8x - 4 = -3x + 32
Move one of the x's. In my case, I will move the -3x. Also move the number as well. I will move the -4
8x + 3x = 11x
32+4 = 36
Now you got: 11x=36

A circle has a center at (1,-2) and radius of 4. Does the point (3.4,1.2) lie on the circle? Justify your answer.
Answers
The point (3.4, 1.2) lies on the circle with center at (1, -2) and radius of 4, as the distance from the point to the circle's center is exactly equal to the circle's radius.
The question asks if the point (3.4, 1.2) lies on a circle with a center at (1, -2) and a radius of 4. To determine this, we can use the distance formula, which calculates the distance between two points in a coordinate plane. The distance formula is √((x_2 - x_1)^2 + (y_2 - y_1)^2), where (x_1, y_1) and (x_2, y_2) are the coordinates of the two points. In this case, the center of the circle is (1, -2) and the point in question is (3.4, 1.2).
To see if the point lies on the circle, we check if the distance from the point to the center equals the circle's radius. Calculating: √((3.4 - 1)^2 + (1.2 - (-2))^2) = √((2.4)^2 + (3.2)^2) = √(5.76 + 10.24) = √16 = 4. Since this distance is exactly 4, which is the circle's radius, the point (3.4, 1.2) does indeed lie on the circle.

39 is not 1---------> the point does not belong to the line
case B.) y = -x + 8
if the point (7, 1) lie to the line
so
for x=7 the value of y must be 1
y=-7+8------> y=1--------> the point belongs to the line
case C.) y = x - 10
if the point (7, 1) lie to the line

Michael has 225 milliliters of a liquid. To find out the number of grams of calcium in this liquid, Michael multiplies the volume by 0.015. When he writes the number representing the amount of calcium in the liquid, how many significant digits will the number have?
Answers
[tex]225*0.015=3.4[/tex]
We can conclude that the number representing the amount of calcium in the liquid will have two significant figures.
Answer:the answer is 2 trust me it had 2 significant digits
Step-by-step explanation:
The reason why is because the number 0.015 only has 2 significant digits is because until a number that is not 0 comes up then it doesn’t count as a significant digit so in this case the number 1 is the number that does start with a zero so thats 1 significant digit and then after that is 5 so they’re is the second significant digit so the 2 other zeros don’t count cause in order for the zero to be a significant digit it has to be to the left of a other number thats not 0 so there’s your answer mark me brailiest pls and have a good day .-. :)

George is playing a board game and hopes to roll a sum of 5 he tosses a pair of number cubes what is the probability that the sum of the numbers tossed will be five
Answers
The probability of rolling a sum of 5 with two dice is 1/9, as there are 4 favorable outcomes out of the 36 possible outcomes when rolling two dice.
The student asked about the probability of rolling a sum of 5 using two fair, six-sided dice (also known as number cubes). To find this probability, we need to consider all possible outcomes that result in a sum of 5 and divide it by the total number of possible outcomes when rolling two dice.
By examining the possible ways to get a sum of 5, we have the following pairs: (1,4), (2,3), (3,2), and (4,1). There are 4 favorable outcomes. Since each die has 6 faces, there are a total of 6 x 6 = 36 possible outcomes when rolling two dice. Thus, the probability of rolling a sum of 5 is 4/36, which reduces to 1/9.
To conclude, the probability to roll a sum of 5 on two dice is 1/9.

Dave has a life insurance policy with $2.2 million benefit. If this money was put into an account with a 3.4% interest rate, how much income can his beneficiaries expect i case Dave dies?
A $74, 800
B $20, 600
C. $60, 000
D $40, 000
Answers
Answer:
Step-by-step explanation:
The maximum value can reach $74, 800 if Dave Dies.
What is Exponential GrowthInsofar as they use compound interest, life insurance premiums are equivalent to bank interest rates. We may use the exponential growth formula to get the insurance policy payout because they are compound interests. Those being the following,
Given:
T = [tex]a(1+r)^t[/tex]
Where:
T is the final payout, a is the initial amount, r is the interest rate in decimal form and t is the time.
So, T = [tex]2200000(1+ 0.034)^t[/tex]
let Dave dies after 2 years of buying his life insurance the beneficiaries will get the following payout.
T = [tex]2200000(1+ 0.034)^2[/tex]
T= 2200000 ( 1.069156)
T = $23,52,143.2
So, the maximum value can reach $74, 800.
