what equation will give the perimeter of the figure? HELP HELP HELP
Answer:
(2l + 2w) + (a + b + c)
Step-by-step explanation:
The formula for the perimeter of a rectangle is
P = 2l + 2w
so if you substitute, it becomes
P = 2(12) + 2(2)
= 24 + 4
= 28
For the perimeter of a triangle the correct formula would be
P = a + b + c
The missing side in the triangle is 3 because 15 - 12 is 3.
If you substitute, it becomes
P = 2 + 3 + 6
P = 11
If we add both perimeters together we get the full perimeter of the figure which is
28 + 11 = 39
I am not sure if you wanted the answer as well but just in case :)
Find BDC of the geometry question.
Answer:
∠ BDC = 54°
Step-by-step explanation:
The inscribed angle BDC is half the measure of its intercepted arc , so
∠ BDC = [tex]\frac{1}{2}[/tex] × 108° = 54°
Isabella is playing a board game. The probability that Isabella will lose a turn on her next turn is 11%. Which word or phrase describes the probability that Isabella will lose a turn?
Answer:
unlikely
Step-by-step explanation:
11% is closer to 0 than it is to 1/2. when something may occur, but significantly less than half of the time, we say it is unlikely

Susan started her homework at 1:59 p.M. And finished her homework 96 minutes later. Susan had volleyball practice at 4:00 p.M.
Answer:
25 minutes
Step-by-step explanation:
usan started her homework at 1:59 pm. And finished her homework 96 minutes later. Susan had volleyball practice at 4:00 p.M. How much time did Susan have between finisng her homework and the beginning of volleyball practice?
1 hour = 60 minutes
If her assignment took her 96 minutes, converted to hours, then it took her 1 hour 36 minutes
Time she finished her assignment = 1:59 + 1:36 = 3:35 pm
time between when she finished and started practice = 4 : 00 - 3:35 = 25 minutes
(c) Charmaine compared the statistics from her team's baseball season. She determined that having fewer hits did not imply that a player
caught more or fewer balls. What should she conclude?
There is no correlation between number of hits and number of balls caught.
There is a correlation between number of hits and number of balls caught. There may or may not be causation. Further studies would have to be
done to determine this.
There is a correlation between number of hits and number of balls caught. However, there is no causation. This is because there is probably a
decrease in the number of balls caught with a decrease in the number of hits.
Answer:
There is no correlation between number of hits and number of balls caught.
A player could be terrible at batting but great at fielding. There is no correlation here.

The graphs of linear functions fand g are shown on the grid.
which function best represented by the graph of g
Answer:
g(x) = 3f(x)
Step-by-step explanation:
We can see that for function g;
When x = 1, y = 3
When x = 2, y = 6
When x = -1, y = -3
When x = -2, y = -6
For function f;
When x = 1, y = 1
When x = 2, y = 2
When x = -1, y = -1
When x = -, y = -2
We can see that the output of g(x) is always 3 times that of f(x) for same values of x.
Thus;
g(x) = 3f(x)
Which graph represents a function
Answer:
Step-by-step explanation:
The second graph represents the function.
To figure out if a graph is a function, use the vertical line test. The vertical line test says that if you draw a line and two points on the graph intersect, that means the function is not a graph. Graph B is the only function where there are no points that fall on the same x value.

Alfred paid $36,187.89 for his new car. If he took out a loan and was given a 3.15 % interest rate compounded semi-annually for ó years, how much did he borrow? Round your answer to the nearest whole number.
Answer:
[tex]A = P(1+\frac{r}{n})^{nt}\\\\[/tex]
A = 36187.89
r= 3.15% = 0.0315
n = 2
t = 6
[tex]36187.89= P(1 + \frac{0.0315}{2} )^{2*6)[/tex]
[tex]36187.89 = P( 1+0.01575)^{12}\\\\P = \frac{36187.89}{1.01575^{12}} = 30000.0024[/tex]
