Find the length of a. Round to 3 decimals.
Answer:
a ≈ 22.184
Step-by-step explanation:
Using the Cosine rule in Δ ABC
a² = b² + c² - 2bc cosA
Here b = 15, c = 12 and A = 110° , then
a² = 15² + 12² - (2 × 15 × 12 × cos110° )
= 225 + 144 - 360 cos110°
= 369 - 360 cos110°
= 492.12725.. ( take the square root of both sides )
a = [tex]\sqrt{x492.12725}[/tex] ≈ 22.184 ( to 3 dec. places )
In July 2008, a forest fire near the Park Yosemite National burned about 53 miles squares of forest. If a square mile equals 640 acres, about how many acres of forest were burned?
Answer:
33,920 acres of forest were burned.
Step-by-step explanation:
In this case, since you know that a square mile is equal to 640 acres, you can use a rule of three to find the acres that are equivalent to 53 square miles:
1 square mile → 640 acres
53 square miles → x
x=(53*640)/1
x=33,920 acres
According to this, the answer is that 33,920 acres of forest were burned.
A ball is kicked upward with an initial velocity of 56 feet per second. The ball's height h (in feet) can be expressed as a function of time t (in seconds) by the equation h = -16t2 + 56t. How much time does the ball take to reach its highest point?
1.75 seconds B) 2.50 seconds C) 2.75 seconds D) 3.50 seconds
Answer:
1.75
Step-by-step explanation:
h(t) = -16t² + 56t
h'(t) = -32t + 56
To find time at max height equate h' to 0
0 = -32t + 56
t = 56/32 = 1.75 s
It takes 1.75 s to reach max highest point
Whats the área and circumference if the diameter is 10mm?
Answer:
78.54
Step-by-step explanation:
Answer:
Circumference of a circle in terms of radius:
Circumference = 2·π·r = 2·3.14·5 = 31.42 mm.(*)
In terms of diameter:
Circumference = π·d = 3.14·10 = 31.4 mm.(*)
In terms of area:
Circumference C = √4·π·A = √4·π·78.54 = 31.42 mm.(*)
Step-by-step explanation:
Note: For simplicity, the operations above were rounded to 2 decimal places and π was rounded to 3.14.
Tina would like to drink 64 ounces of water. How many quarts must she drink?

Choice B) Billy misidentified the first quartile valueChoice C) Billy misidentified the medianChoice D) Billy misidentified the third quartile valueThe correct box plot is shown below.
=====================================================
Explanation:
The first step when constructing a box plot is to sort the data from smallest to largest. That has already been done for us, so we can move to the next step.
For step 2, we need to find the median. This is the middle-most value. Write out all of the values on one horizontal line. Then cross off the first and last values. You'll end up with a smaller set, with two values tossed out. Repeat this process (cross off the first and last items) and keep doing this until you work your way toward the very middle position. There are 19 numbers in this list, which is an odd number, this means that the middle value is in slot 10 (note how 19/2 = 9.5 which rounds to 10). We have 9 values below the median and 9 values above the median. So 9+1+9 = 19 items total.
You should find that the value 55 is at slot 9, and at the very middle. So 55 is the median. Billy marked on the box plot that the median is at 50, so this is one mistake he made. Choice C is one of the answers
Note: the median is the vertical bar inside the box of the box-and-whisker-plot.
-----------------------------
Once you have the median, break the list into two halves like so:
L = {25,25,30,30,35,35,40,45,50}
U = {60,60,60,70,85,90,95,95,105}
L is the lower set of values smaller than the median, U is the upper set of values larger than the median. Set L and set U have 9 items each. Note the median of 55 is not part of set L nor is it part of set U either.
Repeat the process to find the median, but you'll do so on sets L and U separately. The median of set L is 35, so this is the value of Q1 or the first quartile.
The left edge of the box is the visual location of Q1. We can see that Billy marked Q1 at 30, but it should be at 35. So this is another mistake he made. Choice B is one of the answers
The median of set U is 85. We have four values below 85, and four values above 85 in set U. This makes Q3 to be 85. However, Billy marked the third quartile at 80 instead of 85. This is another mistake. Choice D is one of the answers.
--------------------------------
To summarize his 3 mistakes, they are:
He misidentified Q1 (Choice B)He misidentified the median (Choice C)He misidentified Q3 (choice D)The good news is that he got the minimum correct because 25 is the smallest value. The min value is the left-most tip of the left whisker. The max is also in the correct location since 105 is the largest item. As you can probably guess, the max is located at the right-most tip of the right whisker.
See the attached image below to see how Billy should have drawn the box plot.

A triangle has sides with lengths of 15 inches, 20 inches, and 25 inches. Is it a right triangle?
37 inches
Hope this helps!
Answer:
Yes.
Step-by-step explanation:
If the side lengths verify in the Pythagorean theorem, then it is a right triangle.
a² + b² = c²
15² + 20² = 25²
225 + 400 = 625
625 = 625
Since these values come out true when using the Pythagorean Theorem, this triangle is a right trinagle.

Answer:
No, this is not a function. If you place the points, it will not pass the vertical line test. And, in a function, each x-coordinate has to have one y-coordinate. In this problem, there are two x-coordinates of 3, and they both have a different y-coordinate.

Find the measure of arc FV
Answer:
FV = 60
Step-by-step explanation:
VG => 65 × 2 = 130
FH major arc=> 119 × 2 = 238
FH major arc - GH = FG
FG => 238 - 168 = 70
VG - FG major arc = FV
FV => 130 - 70 = 60
Answer:
60 degrees
Step-by-step explanation:
The measure of an inscirbed angle is half the measure of the intercepted arc.
(The measure of the arc is twice the measure of the angle!)
The inscribed angle at V intercepts an arc of 2 x 119 = 238 degrees, so the measure of arc FGH is 238. Subtract arc GH from that, 238 - 168 = 70, so that is the measure of arc FG.
The angle at H intercepts an arc with measure 2 x 65 = 130. The measure of arc VFG is 130. But arc FG is part of that, so subtract its measure from 130. 130 - 70 = 60.
The measure of arc FV is 60 degrees.

5 divided by 3 1/3, by lowest point
Answer:
1.42
Step-by-step explanation:
Answer:
1 1/2
Step-by-step explanation:
Step 1: convert 3 1/3 to improper fraction. Use thus rule a b/c=ac+b/c. 5 divided by 3x3x+1/3
step 2: simplify 3x3 to 9 5 divided by 9+1/3
Step 3: simplify 9+1 to 10. 5 divided by 10/3
Step 4: use the rule a divided by b/c=axc/b 5x3/10
Step 5: use this rule: axb/c=ab/c 5x3/10
Step 6: simplify 5x3 to 15 so 15/10
Step 7: simplify to 3/2
Last step: Convert to a mixed fraction.. Which would leave us with 1 1/2 or 1.5 in decimal form.

The infield of a baseball diamond is shaped like a square. Each side is 90 feet long.
What is the area of the infield?
Answer:
8,100
Step-by-step explanation:
To get the area of a square you must multiply one length by width 90 x 90 = 8100
The area of the infield with each side 90 feet long is,
⇒ Area of the infield = 8100 feet²
What is mean by Multiplication?The multiplication means to add or sum a number to itself a particular number of times. And, The Multiplication can be viewed by a process of repeated addition.
We have to given that;
The infield of a baseball diamond is shaped like a square.
And, Each side is 90 feet long.
Hence, The area of the infield is,
⇒ Area of the infield = side²
Here, We have;
Side of infield = 90 feet
Hence, We get;
⇒ Area = 90²
⇒ Area = 90 x 90 feet²
⇒ Area = 8100 feet²
Therefore, We get the correct answer is;
The area of the infield with each side 90 feet long is,
⇒ Area of the infield = 8100 feet²
