Parallelogram A B C D with sides A B and D C parallel and sides B C and A D parallel. Angle B has measure 63 degrees and side B C has length 10. A line segment connects vertex C to base A D at a right angle.
If AB = 9 and AB ∣∣∣∣ DC
, what is the perimeter of ABCD?
The perimeter of parallelogram ABCD is 43.49 units.
How do we calculate?
We know that BC = 10, so we can use the Pythagorean theorem to find the length of AD:
AD^2 = BC^2 + x^2
AD^2 = 10^2 + x^2
AD^2 = 100 + x^2
AD = √(100 + x^2)
Perimeter = AB + BC + CD + AD
Perimeter = 9 + 10 + 9 + √(100 + x^2)
angle B has measure 63 degrees and we can use the sine function to find x:
sin 63 = x / √(100 + x^2)
x / √(100 + x^2) = sin 63
x = sin 63 * √(100 + x^2)
x = 0.819 * √(100 + x^2)
x / 0.819 = √(100 + x^2)
x^2 / 0.6761 = 100 + x^2
x^2 / 0.6761 - x^2 = 100
x^2 * (1 / 0.6761 - 1) = 100
x^2 = 100 / (1 / 0.6761 - 1)
x = √(100 / (1 / 0.6761 - 1))
x = 5.48
We then substitute x back into the expression for the perimeter:
Perimeter = 9 + 10 + 9 +√(100 + x^2)
Perimeter = 9 + 10 + 9 + √(100 + 5.48^2)
Perimeter = 9 + 10 + 9 +√(100 + 30.0304)
Perimeter = 43.49

On a 200 question test you end up getting getting a score of 78% How many questions did you get correct?
Answer: 39.00%
Step-by-step explanation:
First, you need to calculate your grade in percentages. The total answers count 200 - it's 100%, so we get a 1% value, divide 200 by 100 to get 2.00. Next, calculate the percentage of 78: divide 78 by 1% value (2.00), and you get 39.00% - it's your percentage grade.

quarterly, and monthly
(a) The amount in the account after 4 years if the account is compounded semiannually is $0.
(Round to the nearest cent.)
Answer:A=P{1+r/n}^nt. A is the end value, P the start. r is the rate, divided by n, the number of compoundings per year. t is the number of years.
semiannual is 2 compoundings
A=7000{1+(0.055/2)}^6, the 6 from 2 compoundings a year for 3 years. Do the parentheses first, so that you have 1.0.0257^6. When you get that, multiply by $7000. Round at the end, not intermediate steps.
A=$8237.38

A=7000{1+(.055/4)}^12=$8246.48. Notice that what is in the parentheses gets smaller, but it gets raised to a higher power.

The notation "m^2" is a shorthand way of saying "square meters".
Chances are you'll simply type in the number and leave out the units, as that's already taken care of.
==========================================================
Work Shown:
area = base*height
area = 8*3
area = 24 square meters
---------
Explanation:
We simply multiply the base 8 and height 3 and that's our answer. It's not a trick question even if it might seem like it.
The side that's 7 meters long is never used. The base and height are always perpendicular to one another, which means that they form a right angle (aka 90 degree angle).
The area formula of a parallelogram and rectangle are the same. We can think of a non-rectangular parallelogram as a slanted rectangle in a sense. Imagine you had stacks of blocks to form a rectangle. Now imagine nudging that stack slightly to one side. The blocks themselves don't change, so the area of one wall doesn't change. All that's changed is the shape.
Consider the system of equations. Which is the Best method to use for solving the system? 4x+y=1 2x+y=8
The best solution is to use the elimination method. The best approach to utilize is the elimination technique while trying to solve a problem 4x+y=1 2x+y=8.

A carton of 12 eggs cost $2.39, and a carton of 18 eggs cost $3.39. Unit price of the 12-egg carton = ($2.39)(12 eggs) = $28.68 per egg Unit price of the 18-egg carton = ($3.39)(18 eggs) = $61.02 per egg The 12-egg carton has the lower unit cost, so it is the better buy.

Nikki used the calculations shown to determine whether a carton of 12 eggs or a carton of 18 eggs was the better buy.
Here, A carton of 12 eggs cost $2.39, and a carton of 18 eggs cost $3.39.
And, A carton of 12 eggs cost $2.39, and a carton of 18 eggs cost $3.39.
Unit price of the 12-egg carton = ($2.39)(12 eggs) = $28.68 per egg
Unit price of the 18-egg carton = ($3.39)(18 eggs) = $61.02 per egg
The 12-egg carton has the lower unit cost, so it is the better buy.
Here, It's first error is,
She made a computational error when multiplying to find the unit price of the two cartons.
Instead of dividing the cost of the 18-egg carton by the number of eggs, she multiplied the cost by 18, which resulted in an incorrect unit price.

The ensuing equation could then be resolved to search out the worth of the remaining unknown. From here, the second worth is also obtained by subbing the primary worth back to at least one of the equations.Let the amount of 10 % acid solution be " x " and the amount 40 % acid solution be " y " .

Assume that military aircraft use ejection seats designed for men weighing between 132. 4132. 4 lb and 217217 lb. If women's weights are normally distributed with a mean of 168. 7168. 7 lb and a standard deviation of 48. 848. 8 lb, what percentage of women have weights that are within those limits
The percentage of women with weights that are within the limits is:
60.93%
What percentage of women have weights that are within those limits?Can be calculated using the normal distribution formula. First, we need to find the z-scores for both the lower and upper limits:
z-score for lower limit = (132.4 - 168.7) / 48.8 = -0.74
z-score for upper limit = (217 - 168.7) / 48.8 = 0.99
Next, we can use a z-table to find the corresponding probabilities for these z-scores:
Probability for lower limit = 0.2296
Probability for upper limit = 0.8389
Finally, we can subtract the lower probability from the upper probability to find the percentage of women with weights that are within those limits:
Percentage = 0.8389 - 0.2296 = 0.6093
Therefore, approximately 60.93% of women have weights that are within the limits of 132.4 lb and 217 lb.

4 pointsA photographer charges a travel fee plus an additional rate per minute.The table shows the linear relationship between the number of minutes ofa photography session and the total cost including the travel fee.Photography SessionsNumber ofTotal CostMinutes15$52.5030$75.0045$97.5060$120.0090$165.00Which statement is true?The travel fee is $52.50None of the statements are true.All the statements are true.The additional fee per minute of the photography session is $0.50.The additional fee per minute of the photography session is $3.50.The travel fee is $30.00o
The first thing to note is that the relationship is linear. It means that the difference between any consecutive total costs is the same: In this case, such difference is $22.5. After considering the travel fee in the first 15 mn, additional minutes don't depend on the travel fee (because it's fixed). This implies that this $22.5 from the 15 mn to 30mn is just by the additional rate. Thus, the additional rate (A) per minute is
\(A=\frac{22.5}{15}=\text{ \$}1.5\)(then the options talking about the additional fee are wrong).
Now, what is the travel fee? We know the additional rate, so the travel fee (T) is
\(52.50=(1.5\cdot15)+T\)\(52.5-22.5=T\)\(T=\text{ \$}30.00\)It means that the correct answer is the last.

Solve the following equation to find the value of x:
9x-4=5x+12
Answer: x=4
Step-by-step explanation:
First find the smallest x which would be 5x and subtract that from the 9x. So now it should be 4x-4=12. Then, move 4 and add that to the twelve which should now be 4x=16. Then, divide it by four and you get x=4.
Answer:
x = 4
Step-by-step explanation:
We start from
9x - 4 = 5x + 12
We move the "5x" to the left side of the "=" sign by changing it's sign from 5x which can be seen as +5x to -5x
9x - 4 - 5x = 12
Now we move the "4" to the right side of the "=" sign by applying the same principle as above, so -4 turns to +4
9x - 5x = 12 + 4
We than solve the subtraction and addition
4x = 16
Then we divide both sides of the equation by 4 and we get
x = 4
