Answers
Answer:
A. 15π mi
Step-by-step explanation:
First find the circumference
C = 2*pi*r
C = 2 * pi*18
C = 36pi
The arc is 150 degrees
The fraction of the circle is
150/360 = 5/12
Multiply this by the circumference
5/12 * 36 pi

a farmer produced 47581 2 oranges of one kind and 651 65 oranges of another kind He mixed these oranges and packed in 296 boxes how many oranges did he pack in a box?
Answers
Step-by-step explanation:
I am not sure the scanning of the text went well, as this has some strange gaps in the numbers.
I understand that we have 475812 oranges of one type and 65165 oranges of another type.
we have no information, if these types of oranges have significantly different sizes or weight. so, we have to assume that they are reasonably equal to each other.
therefore, the "different type" statement is just to confuse us. the text could have also said that these were 2 different truck loads of the same type.
we only need to deal with the total number of oranges.
so,
475812 + 65165 = 540977 total oranges
he packs them into 296 boxes.
that makes
540977 / 296 = 1827.625 oranges per box.
these are many oranges for one box in real life.
and it is not a round number, which is strange for a home work or test question if this type.
if the farmer truly put only the same number of oranges in every box, he would have
540977 - 1827×296 = 540977 - 540792 = 185
oranges left over.
in any case, these are all signs that there was probably something wrong with the text. but you see the principle up there. please do the same thing with the real numbers.
Numbers of one kind oranges=475812
No of other kind oranges=65165Total oranges
[tex]\\ \sf\longmapsto 475812+65165=540977[/tex]
Total boxes=296Oranges per box:-
[tex]\\ \sf\longmapsto \dfrac{540977}{296}=1827.6[/tex]

Find the value of w
A. 141
B. 110
C. 80
D. 100
Answers
Answer:
141
Step-by-step explanation:
Angle Formed by Two Chords= 1/2(SUM of Intercepted Arcs)
We know z+70 = 180 since they form a straight line
z = 110
z = 1/2 ( 79+w)
110 = 1/2 ( 79+w)
220 = 79+w
220-79 = w
141 =w
The value of w is found to be 141.
ChordWhat is chord of a circle?The line segment connecting any two locations on a circle's circumference is referred to as the chord of the circle.
It should be emphasised that the diameter is the circle's longest chord, which runs through its centre.
Relation between chord and arc:When two chords cross inside of a circle, the angle's measure is equal to the product of the lengths of the intersecting arcs and the vertical angle, divided by two.
Formula for chord angle:angle formed by two chords = 1/2 (sum of intercepted arcs)
Calculation for arc w:Estimate angle z by linear pair.
z + 70 = 180
z = 110
z is the angle formed between two chord of the circle.
Thus,
z = 1/2( 79 + w) {sum of intercepted arcs}
110 = 1/2( 79 + w)
Further solving,
w = 141
Therefore, the value of arc w comes out to be 141.

Step-by-step explanation:
The volume of a cone is

We are given a diameter of 16 so the radius is 1/2 of the diameter or 8
The height is 16

A principal of $4000 is placed in a savings account at 6% per annum compounded annually. How much interest is earned in the account after three years
Answers
The interest earned in the account after three years is $720.
The formula for simple interest= P×T × R/100
Principal (P) = $4000
Time( T) = 3 years
Rate(R) = 6%
interest(I)= 4000×3 × 6/100
I = 72000 ÷ 100

Find the average rate of change of g(x) = 2x^3 - 5 from x= -4 to x= 2
Answers
Step-by-step explanation:
the average change rate is the change of the functional values from the beginning to the end of the interval, and then that divided by the length of the interval.
like with every average or mean value calculation.
g(-4) = 2×(-4)³ - 5 = -128 - 5 = -133
g(2) = 2×2³ - 5 = 16 - 5 = 11
so, on an interval of x values of 2- -4 = 6 units the function changes its values by 11 - -133 = 144 units.
the average charge rate for this x interval is therefore
144 / 6 = 24 = 24/1
for 1 unit change of x, g(x) changes in the average by 24 units.

Step-by-step explanation:
f(x) = (x - 3)(x - 3)(x + 5)
Rewriting
f(x) = (x - 3)^2(x + 5)
Setting equal to zero
0 = (x - 3)^2(x + 5)
Using the zero product property
(x-3)^2 = 0 x+5 = 0
x-3 = 0 x= -5
x=3 x-5

Ken needs a total of $410 to buy a new bicycle. He has $35 saved. He earns $15 each week delivering newspapers. How many weeks will Ken have to deliver papers to have enough money to buy the bicycle?
Thanks so much! :D
Answers
Answer:
25 weeks
Step-by-step explanation:
Since we already know that he has $35 buck-a-roons saved, we can just subtract that from the cost of the bicycle to find the actual price—which would be 375. Then, we know that for every week, he gains $15 bucks. Therefore we know that 15 would be our variable so we can create the following equation:
15x + 35 = 410
15x = 375
15x/15 = 375/15
x = 25
After 25 weeks, Ken will have enough money to buy the bicycle.

Two professional gamers subscribe to twitch streamers. Jonah has 430$ saved up, and spends 45$ a month on
subscriptions. Rodrick has 310$ saved up, and spends 25$ a month on subscriptions.
A) Create an equation that can be used to find m, the number of months it will take for both gamers to have the
same amount of money left?
B) After how many months will the gamers have the same amount of money?
Answers
Answer:
A) [tex]430-45m = 310-25m[/tex]
B) 6 months
Step-by-step explanation:
A) for Jonah, the equation would be [tex]430-45m[/tex]
Because the money is being spent on the subs, you subtract that from his original savings.
The same thing is said for Rodrick, but his equation would be [tex]310-25m[/tex]
to find out the number of months it will take for both gamers to have the
same amount of money left, you set their equations equal to each other:
[tex]430-45m = 310-25m[/tex]
B) you solve for m.
[tex]430-45m = 310-25m[/tex]
first by subtracting 310 on both sides to get:
[tex]430-310-45m=-25m[/tex]
[tex]120-45m=-25m[/tex]
then add 45m on both sides because we cant have negative months
[tex]120=-25m+45m[/tex]
[tex]120=20m[/tex]
divide by 20 on both sides to get the number of months
[tex]\frac{120}{20} =\frac{20m}{20}[/tex]
[tex]m=6[/tex]

Answers
Answer:
A. 30+20+10=50+10=60
Step-by-step explanation:
The commutative property is the property of which you can rearrange the numbers around but the answer stays the same. From the original equation, you moved 20 and 10 around and added 30+20=50 then, you add 10 plus that 50 since you haven't done anything to the 10 yet. So, 50+10=60.
