Help on finding area!
Answer:
b is your answer, 366.7
Step-by-step explanation:
You can split this into 2 shapes to find the area, a rectangle and a circle (split into 2 parts on either end of the rectangle). The area of the rectangle inside is the easiest part, so let's start there.
Area of a rectangle = length x width = 18 x 13 = 234. We'll come back to this number in the last step.
The area of a circle = (pi)(r)^2 = (pi) (radius)(radius).
The radius = 1/2 of the diameter, and the diameter is 13, so the radius = 6.5
We'll use 3.14 for pi, since the answers are in decimals, not fractions.
area = (3.14)(6.5)(6.5) = 132.665
------------------------------
Now add the area of the circle to the area of the rectangle.
234 + 132.665 = 366.665 , rounded to 366.7 on your question.

three letters are selected from the word DISPLAY how many different combination are there
Answer:
pay, say, dip, day, pal, spa, pas.
Step-by-step explanation:
The number of combination of selecting three letters from the 7-letter word (DISPLAY) are 35.
What is arrangement?Arrangement of the things or object is mean to make the group of them in a systematic order, in all the possible ways.
The number of possible ways to arrange is the n!.
Here, n is the number of objects.
The given letter in the problem is DISPLAY. There is total 7 letters in this word. Now here three words have to be selected.
Here, all the 7 letters are different, thus the combination of selecting three letters from the 7-letter word (DISPLAY) can be given as,
[tex]^7C_3=\dfrac{7\times6\times5}{3\times2\times1}\\[/tex]
[tex]^7C_3=35[/tex]
Thus the number of combination of selecting three letters from the 7-letter word (DISPLAY) are 35.

A rotation and a translation

Step-by-step explanation:
Again, we have to rotate to make the shape fit in, right?
But it wouldn't fit... Or will it? If you can take 2 guesses, you can try the rotation and a translation or the rotation.

Answer:
(a) Reflection and rotation
Step-by-step explanation:
The order of the vertices in the original polygon CDEF is clockwise. The order of vertices in the image polygon GEIH is counterclockwise. This means a reflection is involved in the transformation. Rotation with or without translation will not reverse the orientation.
The only choice that includes reflection is ...
A reflection and a rotation
__
A reflection alone cannot do the transformation shown. A reflection together with rotation and/or translation will do it. For example, reflection across the y-axis, and 90° counterclockwise rotation about the point F'. Or, reflection across the line y=-x and translation right 3 and down 1.
A company makes wax candles in the shape of a cylinder. Each candle has a diameter of 6 centimetres and a height of 2 centimetres. How much wax will the company need to make 270 candles?
Use 3.14 for π, and do not round your answer.
Answer:
270 = 15,268.14030 in³
Step-by-step explanation:
A company makes wax candles in the shape of a cylinder. Each candle has a diameter of 6 inches and a height of 2 inches. How much wax will the company need to make 270 (use 3.14 for n, and do not round your answer)?
Volume = π r² h __ 3.14 * 9 * 2 = 56.52 in³ * 270 = 15,260.4 in³
Using a typical ten digit calculator
3.141592654 * 9 * 2 = 56.54866777 in³ * 270 = 15,268.14030 in³ (rounded)
Volume of cylinder = pi x r^2 x height
Volume = 3.14 x 3^2 x 2 = 56.52 cubic cm.
Multiply the volume of a cylinder by total candles:
56.52 x 270 = 15,260.4 cubic cm
Linda Davis agreed to lend money to Alex Luciano at a special interest rate of 9% per year, on the condition that he borrow enough that he would pay her $400 in interest over a -year period. What was the minimum amount Alex could borrow?
9514 1404 393
Answer:
$4444.44
Step-by-step explanation:
The amount of interest on a given principal is found by ...
I = Prt . . . . principal P earning annual rate r for t years.
We want ...
400 = P×0.09×1
P = 400/0.09 ≈ 4444.44
Alex needs to borrow $4444.44.
_____
Additional comment
For exactly $400 in interest, the amount is not an integral number of cents, so some rounding of interest or loan amount must occur. In that case, the minimum to borrow is that which will give a calculated interest of at least $399.995. That amount is $399.994/0.09 ≈ $4444.3888.... ≈ $4444.39. Alex can borrow a minimum of $4444.39 and still have to pay $400 in interest.

What is the area of the parallelogram shown below?
Answer:
8
Step-by-step explanation:
A random sample of 9th-grade students was asked if they prefer taking notes on a computer or using a paper and pencil. Of the 180 students who were surveyed, 75 said they preferred using the computer. The resulting 99% confidence interval for the proportion of students who prefer taking notes on the computer was (0.322, 0.511). The school newspaper ran a story saying that less than half of the student body prefers taking notes on a computer. Based on the interval, is the newspaper justified in this statement?
Answer:
NO
Step-by-step explanation:
since the interval contains values above 0.5, it is plausible that more that 50% of students prefer using a computer for notes.
Using the given confidence interval, since it's upper bound is above 50%, the newspaper is not justified in this statement.
What is the interpretation of a x% confidence interval?It means that we are x% confident that the population parameter(mean/proportion/standard deviation) is between a and b.
Hence, in this problem, we are 99% confident that the proportion is between 0.322 and 0.511. Since the upper bound of the interval is above 50%, there is not enough evidence to say that the proportion is below 50%, hence the newspaper is not justified in this statement.

One number is three less than two times another number. If the sum of the numbers is 15, find the numbers
9514 1404 393
Answer:
6, 9
Step-by-step explanation:
Let x represent one of the numbers. Then the other number is 15-x (because their sum is 15). The relation between the numbers is ...
2x -3 = 15 -x . . . . . three less than twice one number is the other number
3x = 18 . . . . . . add 3+x
x = 6 . . . . . . divide by 3
15-x = 9 . . . . find the other number
The two numbers are 6 and 9.

.Let's say you solve an equation like 3x + 5 = x + 7 and your solution is x = 1. How could you check to make sure your answer is correct?
Answer:
plug in whatever you found for x and see if its equal on both sides.
Step-by-step explanation:
Answer:
To check an answer for an equation, you can substitute the answer you've found in place of the variable you solved it for.
The value of the unknown, x, can be plugged into the equation. You can then compare both sides to see if they are equal.
For your given equation, let's substitute 1 for x in the equation you've given.
3x + 5 = x + 7
3(1) + 5 = 1 +7
Simplify this.
3 + 5 = 8
8 = 8
You know that 8 does equal 8, so your value for x is correct.
I hope this helps you ^^

What is the equation of the line that passes through the point (-3, 1) and has a
slope of -2?
Answer:
y = -2x - 5
Step-by-step explanation:
x1 = -3 , y1 = 1 ; m = -2
point slope form : y - y1 = m(x -x1)
y - 1 = -2(x - [-3])
y - 1 = -2(x + 3)
y - 1 = -2x + 3*(-2)
y - 1 = -2x - 6
y = -2x - 6 + 1
y = -2x - 5
