Answer:
area = 82 cm²
Step-by-step explanation:
The figure comprises a trapezoid, a triangle and a square.
Calculating areas of the three shapes separately and then adding them will give us the required area of the composite figure.
Area of square : (side)²
= (2)²
= 4 cm²
Area of triangle : ½ × b × h
= ½ × 3 × 12
= 3 × 6
= 18 cm²
Area of trapezoid : ½ × (a + b) × h
= ½ × (5+5) × 12
= ½ × 10 × 12
= 5 × 12
= 60 cm²
Now, area of the composite figure :
= 4 + 18 + 60
= 22 + 60
= 82 cm²
Answer:
82 cm²Step-by-step explanation:
If you exclude the square on the bottom, you have a trapezoid with bases of 5 cm and 8 cm and the height of 12 cm.
Its area is:
A = (5 + 8)*12/2 = 78 cm²Add the area of the square with sides of 2 cm:
A = 2*2 = 4 cm²Total area is:
A = 78 + 4 = 82 cm²Will had 64 baseball cards in his collection. He then got 8 more cards. He keeps the cards in a binder. Each page in the binder can hold 9 cards. Complete and solve the equations below to find how many pages of baseball cards Will has.

What number should Rihanna use for the height of the parallelogram if she uses 28 inches for the base
Answer:
[tex]Height = 7in[/tex]
Step-by-step explanation:
Given
See attachment for parallelogram
[tex]Base = 28in[/tex]
Required
What is the height?
The opposite sides of a parallelogram are equal and the height is the distance between the parallel sides.
From the question, we have:
[tex]Base = 28in[/tex]
Also from the question, the difference between the two parallel sides is 7in.
Hence, the height of the parallelogram in 7in

Please help, thanks! Ok so, you pick a card at random, put it back, and then pick another card at random. There are FIVE cards and they are numbered like this: 1, 2, 3, 4, 5. What is the probability of picking a number greater than 1 and then picking a number less than 2? Write the answer as a fraction or whole number. Thank you!
Answer:
[tex]P(x > 1\ and\ x < 2) = \frac{4}{25}[/tex]
Step-by-step explanation:
Given
[tex]S = \{1,2,3,4,5\}[/tex]
[tex]n(S) = 5[/tex]
Required
[tex]P(x > 1\ and\ x < 2)[/tex]
[tex]P(x > 1\ and\ x < 2)[/tex] is calculated as:
[tex]P(x > 1\ and\ x < 2) = P(x > 1) * P(x < 2)[/tex]
Since it is a probability with replacement, we have:
[tex]P(x > 1\ and\ x < 2) = \frac{n(x > 1)}{n(S)} * \frac{n(x < 2)}{n(S)}[/tex]
For x > 1, we have:
[tex]x > 1 = \{2,3,4,5\}\\[/tex]
[tex]n(x > 1) = 4[/tex]
For x < 2, we have:
[tex]x < 2 = \{1\}[/tex]
[tex]n(x < 2) = 1[/tex]
[tex]P(x > 1\ and\ x < 2) = \frac{n(x > 1)}{n(S)} * \frac{n(x < 2)}{n(S)}[/tex]
becomes
[tex]P(x > 1\ and\ x < 2) = \frac{4}{5} * \frac{1}{5}[/tex]
[tex]P(x > 1\ and\ x < 2) = \frac{4}{25}[/tex]
find the value of x in given expression !!

Answer:
Well..They gave you the hint all you have to do is apply the formula
hint: the way a quadratic formula is written is [tex]ax^2 + bx + c[/tex]
So lets do this
axis of symmetry = [tex]\frac{-b}{2a} = \frac{-(-12)}{2(-3)} = \frac{12}{-6} = -2 = x[/tex]

Find the area and the perimeter of the figure below. The figure is composed of small
squares with a side-length of 1 unit and curves that are an arc of a circle.
our answer
Answer:
11.28 units squared
Step-by-step explanation:
Area of a circle is
[tex]\pi {r}^{2} [/tex]
each square has an area of 1
There are four semi-circles, which make two complete circles.
the area of the 5 squares plus the area of the two circles equals the total area.
5 + 2(3.14) = 11.28
what are the next two terms in the sequence?: 1, -2, 4, -8
Answer:
16 and -32Step-by-step explanation:
-2÷1 = -2
4÷(-2) = -2
-8:4 = -2
So this is a geometric sequence with a common ratio of -2
Therefore:
the 5th term: -8×(-2) = 16
the 6th term: 16×(-2) = -32
The following set of data represents the number of votes for the winner of prom queen over the past several years: 87 94 95 70 75 59 53 82 82 68. Find the median number of votes cast
Answer:78.5
Step-by-step explanation:
the median is the middle digit so with 10 different numbers it would be the 5th or sixth number
but you have to first have them in least to greatest order
53,59,68,70,75,82,82,87,94,95
5th+6th/2
75+82= 157
