There Is A Pair Of Parallel Sides In The Following Shape.
What Is The Area Of The Shape.
Solution:
We know that:
Area of trapezoid = [tex]\frac{(a_{1} + a_{2} )h}{2}[/tex] [a₁ and a₂ must be parallel sides]Substitute the parallel side lengths and the height in the formula to find the area of the trapezoid.
Substituting the parallel side lengths and the height in the formula:
Area of trapezoid = [tex]\frac{(a_{1} + a_{2} )h}{2}[/tex]Area of trapezoid = [tex]\frac{(5 + 9 )4}{2}[/tex]Simplifying the RHS:
Area of trapezoid = [tex]\frac{(14)4}{2}[/tex] Area of trapezoid = [tex](7)4[/tex] Area of trapezoid = [tex]28 \ units^{2}[/tex]Thus, the area of the trapezoid is 28 units².
[tex]\\ \rm\Rrightarrow Area=\dfrac{1}{2}(Sum\:of\: parallel\:sides)\times Height [/tex]
[tex]\\ \rm\Rrightarrow Area=\dfrac{1}{2}(9+5)(4)[/tex]

Three cards are selected from a well-shuffled deck of 52 cards. Find the probability that all 3 are Aces.
Answer:
We can divide the pack of cards in two ways
Non Ace cards and Ace cards
Since there are 4 aces in a pack
No of non ace cards will be 52–4=48
The question mentions atleast 1 ace cards so i can pick 1 ace card,2 ace cards or 3 ace cards
Case1:1 Ace card
1 will pick one ace card and 2 non ace cards
It can be done in 4C1*48*C2 ways
= 4*1128 = 4 512 ways
Case 2: 2 Ace Cards
I will pick 2 ace cards and 1 non ace card
It can be done in 4C2 * 48C1 = 6 * 48 =288 ways
Case 3:3 Ace cards
It can be done in 4C3 =4 ways
Therefore the probability is
(4512+288+4)/52C3
=4804/22100=0.217
Step-by-step explanation:
Each month, an American household generates an average of 28 pounds of newspaper for garbage or recycling. Assume the standard deviation is 2 pounds. Assume the variable is approximately normally distributed. If a household is selected at random, find the probability of its generating:
1) Between 27 and 31 pounds per month.
2) More than 30.2 pounds per month.
Please explain!
a) For x = 27:
z = 27-28/2 = -0.5
For x = 31:
z = 31-38/2 = 1.5
From the normal distribution table, P(27 < x < 31) = P(-0.5 < z < 1.5) = P(z < 1.5) - P(z < -0.5) = 0.9332 - 0.3085 = 62.47%
b) For x > 30.2:
z = 30.2-28/2 = 1.1
From the normal distribution table, P(x > 30.2) = P(z > 1.1) = 1 - P(z > 1.1) = 1 - 0.8643 = 13.57%

The value of y is 10 after executing the statements because the addition of numbers, subtraction, multiplication, and division option (c) 10 is correct.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that is +, -, ×, and ÷.
It is given that:
The value x = 4
y = x + 1
y = 4 + 1
y = 5
The number expression can be defined as the combination of constants and variables with mathematical operators.
x= 3
y = 5(2)
y = 10
Thus, the value of y is 10 after executing the statements because the addition of numbers, subtraction, multiplication, and division option (c) 10 is correct.

Match each circumference to the corresponding radius or diameter of the circle. (All circumferences are approximate.)
circumference: 34.54 units
circumference: 59,66 units
circumference: 23.236 units
circumference: 26.376 units
circumference: 13.188 units
circumference: 29,83 units
radius: 4.2 units
diameter: 7.4 units
diameter: 11 units
Answer:
•26.376 units
•23.236 units
•34.54 units
•59.66 units
Step-by-step explanation:
The formula for the circumference of a circle is ...
C = 2πr = πd
C = 2(3.14)r = 6.28r or C = 3.14d
where r is the radius and d is the diameter.
Put the given radius or diameter into the relevant formula and compute the product. The results are all in "units".
r = 4.2 ⇒ C = 6.28×4.2 = 26.376
d = 7.4 ⇒ C = 3.14×7.4 = 23.236
d = 11 ⇒ C = 3.14×11 = 34.54
r = 9.5 ⇒ C = 6.28×9.5 = 59.66

Answer:
( 7 , 4 )
given:
4x + 10y = 684x - y = 24make y the subject in equation 2:
4x - y = 24
-y = 24 - 4x
y = 4x - 24
insert this in equation 1:
4x + 10y = 68
4x + 10(4x - 24) = 68
4x + 40x - 240 = 68
44x = 68 + 240
44x = 308
x = 7
solve for y:
y = 4x - 24
y = 4(7) - 24
y = 4
Which of the following pairs of numbers gives a sum that is a prime and a product that is composite is it 2 and 9, 3 and 7 or 4 and 8
Step-by-step explanation:
2 and 9
3 and 7
4 and 8
what I see right away : the only pair whose sum is a prime number (or only just an uneven number) is 2 and 9.
2 + 9 = 11
3 + 7 = 10
4 + 8 = 12
just because these sums are even numbers they cannot be prime numbers and are "out".
A composite number is a positive integer that can be formed by multiplying two smaller positive integers different than 1.
so, the product of 2 numbers is therefore always a composite number, and the question in that direction is completely redundant (without any additional meaning).
so, again, 2 and 9 is the right answer.
Gabby walks 12 blocks east from school and then 16 blocks south. Each block is 50 yards. How far is Gabby from school in yards?
Answer:
1000 yards
Step-by-step explanation:
First, create a triangle using the two known amounts.
12 blocks east will act as your base and 16 blocks south as your height. Connect these two lines to form a triangle.
This becomes a matter of the Pythagorean theorem or A^2 + B^2 = C^2
A= 12
B= 16
12^2 + 16^2 = C^2
400 = C^2
C= 20 blocks
Multiply this number by 50 to get the number in yards.
20 * 50 = 1000 yards

A hockey team will play 45 games this season. If they expect 95 people to attend each game, how many people do they expect to attend in all?
people
Answer:
4275
Step-by-step explanation:
You have to do 95 * 45
The way I do this would be, 95 is close to 100, and doing 100 * 45 is much easier than 95 * 45.
100 * 45 is 4500 but ofc that isn't the answer, since we are using 100 and not 95 we have to subtract 5 * 45 which is also a fairly simple equation to solve
5*45 is 225, so what we have to do now is take our 4500 and subtract our 225
4500 - 225 = 4275
Answer:
4,275
Step-by-step explanation:
Give 95 people for each game.
there is only one easy step, you multiply:
