This is the first year Janis is playing softball. She has been practicing her batting. On her last swing the bat made an arc with a radius of 49 inches and swept
through 283 of rotation. Assuming the arc is circular, what is the distance the tip of the bat travels to the nearest inch?
Answer:
2*pi*49*283/360=242 (to the nearest inch)
the distance the tip of the bat travels 242 inches.

Point P is plotted on the coordinate grid. If point S is 12 units to the left of point P, what are the coordinates of point S? 10 NAG -12-10-864 -20 32 2 4 6 8 10 12 TP -6 -S 10 - 12 (6.-16) (-6.-16) o(-6,-4) (6,4)
Answer:
(-6, -4)
Step-by-step explanation:
Original coordinates: (6, -4)
POINT S IS 12 UNITS TO THE LEFT OF POINT P.
There are multiple ways to solve this, but I will explain the easiest way.
We can subtract 12 from the x-coordinate.
This because the x-axis runs RIGHT and LEFT.
The y-axis runs UP and DOWN.
6 - 12 = -6
The y-coordinate stays the same.
The new coordinates are: (-6, -4).
Quick question, so if I put a certain or any amount of points for a question will they be deducted from my points?
Also what happens if I have 0 points, can I no longer ask people questions?
Here's a free 30pts btw.
Answer:
if u have o points u have to answers people questions correctly u can't ask people for questions u need a 10 point then u can but no points me no answers
Answer:
Yes, they will be deducted from your own points. If you have zero points you will no be able to ask questions because the minimum points it is to ask a question is 10 points, but you can always gain points by answering others questions :D

To convert a distance of 13,000 feet to miles, which ratio could you multiply
by?
Answer:
2.46212121 miles
-
convert a mile measurement to a foot measurement, multiply the length by the conversion ratio. The length in feet is equal to the miles multiplied by 5,280
The mile, sometimes the international mile to distinguish it from other miles, is the British imperial unit and the US customary unit, both systems are based on the older English unit of length equal to 5,280 feet, or 1,760 yards, and standardised as exactly 1,609.344 metres by international agreement in 1959
To convert 13,000 feet to miles, you can multiply it by the ratio of 1 mile / 5,280 feet.
To convert a distance of 13,000 feet to miles, you can multiply it by the conversion factor of 1 mile divided by 5,280 feet.
We know that
1 mile= 5280 feet
Then we will use the ratio of 1 mile / 5,280 feet, the numerator 1 represents the equivalent distance in miles, and the denominator 5,280 represents the equivalent distance in feet.
So, 13000 feet x 1 mile/ 5280 feet
= 13000/ 5280
= 2.462121212121212 miles
Therefore, to convert 13,000 feet to miles, you can multiply it by the ratio of 1 mile / 5,280 feet.

A brand of uncooked spaghetti comes in a box that is a rectangular prism with a length of 10 inches, a width of 3 inches, and a height of 4 1/2 inches. What is the surface area?
Answer:
The surface area is 177 square inches
Step-by-step explanation:
Given
[tex]Length = 10[/tex]
[tex]Width = 3[/tex]
[tex]Height = 4\frac{1}{2}[/tex]
Required
The surface area
This is calculated as:
[tex]Area = 2 * (Length * Width + Length * Height + Width * Height)[/tex]
So, we have:
[tex]Area = 2 * (10* 3+ 10* 4\frac{1}{2}+ 3* 4\frac{1}{2})[/tex]
[tex]Area = 2 * (30+ 45+ 13\frac{1}{2})[/tex]
[tex]Area = 2 * (88\frac{1}{2})[/tex]
[tex]Area = 177[/tex]

Step-by-step explanation:
7- The volume of a rectangular pyramid is:
V=(l x w x h) / 3We just have to substitute the values:
V= 13×12×15 / 3V= 780 m8- The volume of a cone is:
V=hπr² / 3Let's substitute the values and solve:
24×π×19.4² / 39,458.9If you want to round it, the answer will be:
9,459 cm9- The volume of a square pyramid V = a²h / 3, where a is the base and h the height.
So,
V= 12²×18 / 3864 cm10- The volume of the cone is V = hπr² / 3
Then,
V= 16×9×π / 39 is the diameter, which is the radius two times. As you see, what the formula asks is for the radius at the second power -multiplied by itself two times-, but if we get the diameter value instead, there is no need to multiply it. The diameter stays the same.
V= 150.7If you want to round it to the nearest tenth, the answer is:
151 in.Hope this helps!!

Find the Volume of the figure
Answer:
1920 cm³
Step-by-step explanation:
V = w · h · l
V = 8 · 14 · 10
V = 1120 cm³
Now for the smaller one.
V = w · h · l
V = 8 · 10 · 10
V = 800 cm³
1120 cm³ + 800 cm³
1920 cm³
Answer:
1920 cm ^3
Step-by-step explanation:
find the volume of the 2 cuboids seperatly.
bigger one: LXWXH --> 8 X 14 X 10 = 1120
smaller one: LXWXH --> 10X10X8 = 800
add them up
1120 + 800 = 1920 cm

1. devin is making a candle by pouring melted wax into a mold in the shape of a square pyramid. each side of the base of the pyramid is 6 cm and the height of the pyramid is 9 cm. to get the wax for the candle, devin melts cubes of wax that are each 4 cm by 4 cm by 4 cm. how many of the wax cubes will devin need in order to make the candle? show your work.
Answer:
1.6875
Step-by-step explanation:
Volume of a pyramid = 1/3 (l*w*h)
Volume = 1/3(6 * 6 * 9)
Volume = 2 * 6 * 9
Volume = 108 cm³
Volume of cube = s³ ; s = side length
Volume = 4³ = 4 * 4 * 4 = 64 cm³
Number of wax cube = Volume of pyramid / volume of cube
= 108 cm³ / 64 cm³
= 1.6875

I'll do problems 13 and 14 to get you started.
=====================================================
Problem 13
Answer: 32 degrees-----------------------
Explanation:
Refer to the diagram below for problem 13. Since BD is a tangent of the circle, this means angle ABD is 90 degrees, and furthermore x+y = 90. This solves to y = 90-x.
If we focus on triangle ABC, then we can add the interior angles and set the sum equal to 180
A+B+C = 180
z+y+y = 180
z+2y = 180
z+2(90-x) = 180 .... plug in y = 90-x
z+180-2x = 180
z-2x = 180-180
z-2x = 0
z = 2x
We'll use this later.
Now move onto triangle ABD. This is a right triangle due to angle ABD being 90 degrees. The acute angles z and 26 are complementary, meaning they add to 90. So,
z+26 = 90
z = 90-26
z = 64
Now plug this into z = 2x and solve for x
z = 2x
64 = 2x
2x = 64
x = 64/2
x = 32
=====================================================
Problem 14
Answer: 31 degrees-----------------------
Explanation:
Refer to the image shown below for problem 14. Like before, I've added various labels to it to help find the angle we're after (the red angle x).
Note how I've drawn a dashed line from point A to point D. This splits up quadrilateral ABCD into two triangles ABD and ACD. These triangles can be shown to be congruent using the HL (hypotenuse leg) theorem.
The congruent triangles also implies that angle DBC and angle BCD are the same measure (both are shown in green as the variable y).
Focus on triangle BCD. It has interior angles of: y, y and 62. Add them up, set the sum equal to 180.
y+y+62 = 180
2y+62 = 180
2y = 180-62
2y = 118
y = 118/2
y = 59
As the image attachment mentions, the angles x and y add to 90 degrees. This is because angle ABD is 90 degrees, due to segment BD being tangent to the circle. So x+y = 90 leads to x = 90-y, and therefore,
x = 90-y
x = 90-59
x = 31
Side note: it is not a coincidence that we ended up with half of the value of 62.
At a football game, 8% were supporting the visiting team. If 2576 people attending
supported the home team, what was the total number of people attending the game?
Answer:32,200
Step-by-step explanation:
8% is 2576, a simple way to solve for this is to find 1% and that would be 322, then multiply by 100 and you get the total number of people attended, this is not the best method but works in this situation with whole numbers.
Number of people attended the game = 32200
What is percentage?A percentage is a number or ratio that can be expressed as a fraction of 100. If we need to calculate a percentage of a number, divide that number by the whole number and multiply by 100. Percentages therefore mean fractions of 100.
Given,
Total number of supporter = 2576
Percentage of supporters = 8%
Let total number of attendees = x
the,
8% of x = 2576
8x/100 = 2576
8x = 257600
x = 257600/8
x = 32200
Hence, 32200 people attended the game.
