Answer:
5509 yes votes
Step-by-step explanation:
We will start by adding together our ratio, so we know how many voters there were in a total ratio, so we can divide our total number of people by it, and then multiply it by the number of people who said yes (7 people).
Our ratio was 7:4, so adding those two numbers together gives us 11. Then, dividing 8657 by 11 gives us:
8657 / 11 = 787
Now, we will multiply 787 by 7, since that was the number of people who said yes:
787 * 7 = 5509
So, there were 5509 yes votes.
Hope this helped!

The formula for the volume, V, of a sphere with radius r is V=4/3 pi(r^3). If the radius of a baseball is 1 3/10 inches, what is the volume to the nearest cubic inch
The volume of the baseball to the nearest cubic inch is 9 cubic inches.
What is Sphere?A sphere is a three dimensional figure which consists of set of all the points which are at an equal distance from a point called the center of the sphere.
Volume is the space occupied by a three dimensional object.
Given that,
Radius of a baseball = 1 3/10 inches = (1 × 10 + 3) / 10 = 13/10 inches.
Also we know that,
Volume of a sphere = 4/3 π r³, where r is the radius.
Volume of the baseball = 4/3 π (13/10)³
= 4/3 π (1.3)³
= 4/3 π × 2.197
= 2.9293 π
= 2.9293 × 3.14

The model of a train is 5.5 in. The scale of that
model is 1: 40. What is the actual length of the
train ?
____feet.
The actual length of the train is calculated to be 18.33 feet
How to get the actual length of the trainScale factors are used to increase or decrease image. The situation of increment is usually called enlargement, and it is case for the problem.
solving for the factor, assuming the factor is k, using the ratio 1 : 40. the scale factor is 40 / 1 = 40
Solving for the actual length
actual length = scale facto * model length
actual length = k * 5.5 in
actual length = 40 * 5.5 in
actual length = 220 in
converting to feet
12 in = 1 foot
220 in = ?
cross multiplying
12 * ? = 220
? = 220 / 12
? = 18.33 feet

Answer:
4) 100
5) 120
Step-by-step explanation:
Finding unknown angle in polygon:4) Number of sides in the polygon = n = 6
Sum of all the angles of n-sided polygon = (n -2)* 180
= (6 - 2) *180
= 4 * 180
= 720
x + x + 9 + 90 + 120 +156 + 145 = 720
Combine like terms,
2x + 520 = 720
Subtract 520 from both sides,
2x = 720 - 520
2x = 200
Divide both sides by 2,
x = 200÷2
[tex]\sf \boxed{x = 100^\circ}[/tex]
5) Sum of all the angles of 5 sided polygon = ( 5 - 2)*180
= 3 * 180
= 540
x + x + x + x + 60 = 540
4x + 60 = 540
4x = 540 - 60
4x = 480
x = 480 ÷ 4
[tex]\sf \boxed{x = 120^\circ}[/tex]
Answer:
4.) You need 720 degrees sum for 6 sided polygon.
5.) You need 540 degrees for a 5 sided polygon.
Step-by-step explanation:
4.) -
120 + 156 + 145 + 90= 511
720 - 511 = 209.
209 - 9 = 200
200 / 2 = 100
X is equivalent to 100 Degrees
-
5.) -
Since X is the same for all sides we'll take 60 from 540 = 480
480 / 4 = 120
X = 120

Jane and Mary are Comic book fans, and each one has collected all n of the limited-edition Comic book figurines, with no repeats. Jane and Mary would each like to display some subset of their collection at the upcoming Comic book convention. However, Mary does not want to be outdone. He must include every figurine that Jane brings, and at least one additional figurine. How many ways can Mary and Jane choose figurines in such a way for the convention?
Mary and Jane have multiple ways to choose their subset of figurines for the comic book convention.
How to illustrate the number of ways?We know that Mary must include every figurine that Jane brings, so Mary must choose a subset of her collection that is at least x+1 figurines.
Since Mary must also choose at least one additional figurine, the total number of figurines that Mary can choose from is n-(x+1) + 1 = n-x
The total number of ways that Mary and Jane can choose their subsets is the product of the number of ways each can choose their subsets.
So, the number of ways is
(choose x out of n) * (choose x+1 out of n)
This is also known as binomial coefficient, which can be represented as nCx or (n x)
Hence the number of ways is
nCx * (n-(x))C(x+1)

It's not possible to build a triangle with side lengths of 3, 3, and 9.
O A. True
OB. False
SUBM
Explanation:
The shorter side lengths 3 and 3 add to 3+3 = 6, which is not larger than the remaining side 9. This is why a triangle is not possible.
For a triangle to be possible, we need the sum of any two sides to be larger than the third side. Refer to the triangle inequality theorem.
I recommend making slips of paper that are 3 inches, 3 inches, and 9 inches long (or replace "inches" with "centimeters"). Then try to make a triangle with those slips of paper. You should find such a task is impossible: as mentioned, the 3 inch sides come up short when trying to attach to the 9 inch side.
The statement "It's not possible to build a triangle with side lengths of 3, 3, and 9" is true.
What is a triangle?A triangle is a 2-D figure with three sides and three angles.
The sum of the angles is 180 degrees.
We can have an obtuse triangle, an acute triangle, or a right triangle.
We have,
A triangle cannot be formed with side lengths of 3, 3, and 9.
To form a triangle, the sum of the lengths of any two sides must be greater than the length of the third side.
However, in this case, the sum of the lengths of any two sides is 3+3=6, which is less than the length of the third side, 9.
Therefore, it is not possible to form a triangle with side lengths of 3, 3, and 9.
Thus,
The statement "It's not possible to build a triangle with side lengths of 3, 3, and 9" is true.

What is an equation?In Mathematics, an equation can be defined as a mathematical expression which shows that two (2) or more thing are equal.
Next, we would write the equation that gives n, the number of leaves Aidan would have after collecting leaves for an art project as follows:
The number of leaves that Aidan collected from 8 different trees is equal to 8 leaves. Additionally, Aidan picks 12 leaves from each tree to have a total of 96;
n = 8 × 12 = 96.
Lastly, Aidan lost 7 leaves on his way home. Therefore, we would subtract 7 leaves from the total number of leaves that Aidan collected from 8 different trees;
