Answer:
the answer is 35 cm
Step-by-step explanation:
to make sure that you dont have a problem next time here is a formula
area of any polygon is the sum of all sides so 9 + 9 + 12 + 5 = 35
To find the area of ABCDE, the two equations you will need are:
Rectangle = l • w
Triangle = (b • h)/2
Since rectangles are symmetrical, we can ignore the triangle for now.
Observe that the left side of the rectangle states 5 cm, and the bottom side states 12 cm. With this information we can infer that:
Area of rectangle is 12cm(5cm) = 60cm^2
Alright, now we can look at the triangle. What we’ll do is subtract 5cm from 9cm to get the height 4 cm; and we’ll subtract 9 cm from 12 cm to get the base 3 cm.
With this information, we can conclude that the area of the triangle (3cm(4cm)/2 = 6cm^2
Adding both the triangle and rectangle area together, we get 66cm^2

A spinner is divided into five colored sections that are not of equal size: red, blue, green, yellow , and purple. The spinner is spun several times, and the results are recorded below: Spinner Results Color Frequency 18 15 Red Blue Green Yellow Purple 20 18 13 Based on these results , express the probability that the next spin will land on purple as a decimal to the nearest hundredth.
Answers
Answer:
0.15
Step-by-step explanation:
The probability would be the amount of times the pointer landed on purple divided by the total times the pointer was spun.
This would be 13/(18+15+20+18+13) = 13/84 = 0.15476
The probability that the next spin will land on purple nearest hundredth will be 0.15.
What is probability?Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences.
Then the probability is given as,
P = (Favorable event) / (Total event)
The table is given below.
Color Frequency
Red 18
Green 15
Blue 20
Yellow 18
Purple 13
Based on these results, the probability that the next spin will land on purple in decimal to the nearest hundredth is calculated as,
P = 13 / (18 + 15 + 20 + 18 + 13)
P = 13 / 84
P = 0.15
The probability that the next spin will land on purple nearest hundredth will be 0.15.

The fourth term of an exponential sequence is 108 and the ratio is 3 . Calculate the value of the eighth term of the sequence, calculate the sum of the first five terms of the sequence.
Answers
Answer:
8th term = 8748 , Sum of 5 terms = 484
Step-by-step explanation:
Formula for nth term in an exponential sequence = a r^ (n-1)
Here : n = 4 , ratio r = 3 ; And nth ie 4th number = 108
So, a r^ (n-1) = nth item implies that → a 3 ^ (4-1) = 108
a 3^3 = 108 → 27 a = 108 → a = 108 / 27 → a = 4
8th term = a r^ (n-1) , at n = 8. So, = 4 3^(8-1) = 4 3^7 = 4 x 2187 = 8748
Sum of n terms = a [(r^n) -1 ] / [r - 1] → Sum 5 terms = 4 [ (3^5)- 1] / [3 - 1]
= 4 [ (243) - 1] / 2 ] = 2 x 242 = 484

James cut out four parallelograms, the dimensions of which are shown below. Parallelogram 1 length: 12 in. width: 15 in. diagonal: 20 in. Parallelogram 2 length: 16 in. width: 30 in. diagonal: 34 in. Parallelogram 3 length: 20 in. width: 21 in. diagonal: 29 in. Parallelogram 4 length: 18 in. width: 20 in. diagonal: 26 in. James put the parallelograms together so one vertex from each paper exists on a point, as shown in the circle. 4 parallelograms are put together so that one vertex from each paper exists on a point. Which statement explains whether or not the parallelgrams can be put together so each occupies one-quarter of the area of the circle without overlapping any other pieces? Check all that apply. The quadrilaterals can be placed such that each occupies one-quarter of the circle. The quadrilaterals cannot be placed such that each occupies one-quarter of the circle because the vertices of parallelogram 1 do not form right angles. The quadrilaterals cannot be placed such that each occupies one-quarter of the circle because the vertices of parallelogram 2 do not form right angles. The quadrilaterals cannot be placed such that each occupies one-quarter of the circle because the vertices of parallelogram 3 do not form right angles. The quadrilaterals cannot be placed such that each occupies one-quarter of the circle because the vertices of parallelogram 4 do not form right angles.

Answers
Answer:
a) one solution(x = 9)
b) no solution
c) infinite solutions
Step-by-step explanation:
a) To solve this equation, we can add 4 on both sides in order to isolate x:
x - 4 =5
+ 4 + 4
x = 9
Since x equals 9, that counts as only one solution, as there is only one value of x that makes the equation true.
b) We start by subtracting 2x from both sides to combine the variable terms:
2x - 6 = 2x + 5
-2x -2x
-6 = 5
The statement, -6 = 5 is never true and it is not dependent on the value of x. This means there are no solutions to this equation.
c) We can start by subtracting 3x from both sides to combine the terms with x:
3x + 12 = 3x + 12
-3x -3x
12 = 12
The statement above is always true, and no matter the value of x, it will always be true. This means there are infinite solutions to the equation.
Does anyone know how to solve this?

A hemispherical tank is filled with water and has a diameter of 12 feet. If water weighs 62.4 pounds per cubic foot, what is the total weight of the water in a full tank, to the nearest pound?
Answers
Answer:
The total weight = 1286 × 62.4 = 80246 pounds.
Step-by-step explanation:
The formula of the volume of the sphere is
V = 4/3×π×r³
Given
d = 17 feet
d = 2r
r = d/2 = 17/2 = 8.5 feet
V = 4/3×π×r³
Since we need half of the volume as it is a hemispherical tank.
= 1286 ft³
Given that the weighs 62.4 pounds per cubic foot
Thus, the total weight = 1286 × 62.4 = 80246 pounds.

The student rolls the cube 100 times and lands with 6 facing up 20 times. The P-value for the test of the hypotheses, H0:p=0.17 and Ha:p>0.17, is 0.19. What is the correct conclusion given a=0.05?
Because the P-value is less than a=0.05, the student should reject H0.
Because the P-value is less than a=0.05, the student should reject H0.
Because the P-value is greater than a=0.05, the student should reject H0.
Because the P-value is greater than a=0.05, the student should fail to reject H0.
