Answer:
[C] 36.
Step-by-step explanation:
the given polygon is trapezoid, where its bases are AB and CD.
The required area can be calculated using the formula: A=0.5(AB+CD)*h, where h - height of the ABCD.
The lengths are: AB=6; CD=12; h=4, then the required area:
A=0.5(6+12)*4=36

Answer:
f = ab/(a + b)Step-by-step explanation:
#14Given:
1/f = 1/a + 1/bSolving for f:
1/f = b/ab + a/ab1/f = (a + b)/ab cross - multiplyf(a + b) = ab divide by (a + b)f = ab/(a + b)The outcomes of an experiment and the probability of each outcome are given in the table below. Compute the expectation for this experiment.
Answer:
Step-by-step explanation:
sum the outcome times the probabilities
5*.5+6*.12+7*.2+8*.08+9*.06+10*.04= 6.2
The expectation of the experiment is the mean or the average value of the experiment
The expectation of the experiment is 6.2
The expectation is calculated using the following formula of expected value
[tex]E(x) = \sum Outcome \times Probability[/tex]
Rewrite the formula properly, as:
[tex]E(x) = \sum x \times p(x)[/tex]
So, we have:
[tex]E(x) = 5 \times 0.5 + 6 \times 0.12 + 7 \times 0.2 + 8 \times 0.08 + 9 \times 0.06 + 10 \times 0.04[/tex]
Evaluate the above equation
[tex]E(x) = 6.2[/tex]
Hence, the expectation of the experiment is 6.2

A new car sells for $27,300. It exponentially depreciates at a rate of 6.1% to $22,100. How long did it take for the car to depreciate to this amount? Round your answer to the nearest tenth of a year. fill in the blank 1
Answer:
3
Step-by-step explanation:
27300 * (1-6.1%)^n = 22100,
n∈(3,4)
when n = 3,≈22603;
when n = 4,≈21224;
so choose n = 3.
Therefore, it takes car to depreciate to this amount is [tex]3[/tex].
What is the simplification?
Simplification is reducing the expression/fraction/problem in a simpler form. It makes the problem easy with calculations and solving.
Here given that,
A new car sells for $[tex]27,300[/tex]. It exponentially depreciates at a rate of [tex]6.1[/tex]% to $[tex]22,100[/tex].
So, the equation is
[tex]27300(1-6.1)^n=22100\\\\[/tex]
when [tex]n[/tex] belongs to [tex](3,4)[/tex]
when [tex]n=3\\[/tex]
The equation would be
[tex]27300(1-6.1)^3=22100\\\\=22603[/tex]
When
[tex]n=4\\27300(1-6.1)^4=22100\\=21224[/tex]
So, the time it takes to depricate to the given amount is [tex]22603[/tex] when [tex]n=3[/tex].
Hence, it takes car to depreciate to this amount is [tex]3[/tex].

Answer:
3.46 pounds6.92 pounds13.84 poundsStep-by-step explanation:
The most accurate ratio of pounds to dollars will be found using the given numbers that have the most significant figures. Those are found on the last row of the table:
pounds/dollar = 34.60/50 = 0.692
To find the other table values, multiply the dollar amounts by this constant of proportionality. The problem statement tells you to round the result to hundredths.
$5 ⇒ 5.00 × 0.692 = 3.46 pounds
$10 ⇒ 10.00 × 0.692 = 6.92 pounds
$20 ⇒ 20.00 × 0.692 = 13.84 pounds
_____
You can also fill in the table by recognizing that $5 is one tenth of $50, so the number of pounds will be one tenth of 34.60 = 3.46. Then each of the following rows doubles the amount on the previous row.

Solve the compound inequality
Answer:
1 < x < 7
Step-by-step explanation:
1. Solve for 2(x - 3)
Step 1: Simplify both sides of the equation.
[tex](2)(x)+(2)(-3)<8[/tex] [tex]2x - 6 < 8[/tex]Step 2: Add 6 to both sides.
[tex]2x - 6 + 6< 8 + 6[/tex] [tex]2x < 14[/tex]Step 3: Divide both sides by 2.
[tex]\frac{2x}{2} <\frac{14}{2}[/tex] [tex]x< 7[/tex]2. Solve for x + 5 > 6
Step 1: Subtract 5 from both sides.
[tex]x + 5 - 5 > 6 - 5[/tex] [tex]x > 1[/tex]3. Now that we know x is more than one but less than 7, we can write the solution as this: 1 < x < 7.
Therefore, the answer is 1 < x < 7.
Answer: 1. Solve for 2(x - 3) Step 1: Simplify both sides of the equation. Step 2: Add 6 to both sides. Step 3: Divide both sides by 2. 2. Solve for x + 5 > 6. Step 1: Subtract 5 from both sides.

draw a square and its diagonals how many angles are formed by the intersection of the diagonals?
A square has 2 diagnals. imagine 2 lines connecting every opposite angle of the square. that leaves 2 intersecting lines. Sinse the two lines are intersecting, they form angles. Because there are only 2 lines, there are 4 angles. The answer is 4.
A square is a four-equal-sided figure with the diagonals of the square cut perpendicular to each other as shown below and the number of angles formed by diagonals is 4.
What is a square?A square is a geometrical figure in which we have four sides each side must be equal and the angle between two adjacent sides must be 90 degrees.
Area of square = Side²
The perimeter of the square = 4× side
A square is a geometrical figure in which we have four sides each side must be equal and the angle between two adjacent sides must be 90 degrees.
There are two diagonals in every square.
The angle of intersection between both diagonals is 90 degrees.
The number of angles formed by diagonals = 4
Hence "A square is a four-equal-sided figure with the diagonals of the square cut perpendicular to each other as shown below and the number of angles formed by diagonals is 4".

Answer:
2 7/16
Step-by-step explanation:
2 3/4 - 5/16 → 11/4 - 5/16 (convert 2 3/4 into an improper or top-heavy fraction)
11/4 - 5/16 → 44/16 - 5/16 (multiply 11/4 by 4/4 to make a common denominator)
44/16 - 5/16 = 39/16 (Subtract 44 - 5 = 39)
Simplify (convert back into mixed number)
39/16 = 2 7/16
