Residents of a small city voted on whether
to allow a developer to build a shopping
center. The number of votes in favor of the
shopping center was 3,400. The number of
votes against the shopping center was 15,600.
What percent of the voters were in favor of
building the shopping center?
What percent of the voters were against of
building the shopping center?
Answers
Add the two numbers together to find total votes:
3,400 + 15,600 = 19,000 total votes.
Divide votes for by total votes:
3,400 / 19,000 = 0.1789
Multiply by 100:
0.1789 x 100 = 17.89% voted for it.
Subtract the percent that votes for it from 100%
100% - 17.89% = 82.11% voted against it.
The answers probably need to be rounded, so 18% for, and 82% against.

Answer:
1/12 ( -x -4 )
Step-by-step explanation:
1/12 ( -x - 4 )
1/12(-x) = -1/12x Multiply 1/12 and -x to get -1/12x.
1/12 x -4 = -1/3 Multiply 1/12 and -4 to get -1/3.
So, therefore, the expression 1/12 ( -x - 4 ) is equivalent to -1/12x - 1/3.

The value if x is 0.9875.
Step-by-step explanation:
First, we have to get rid of brackets by expanding :
[tex]0.5(2x + \frac{3}{4} ) - \frac{1}{3} (0.1 + x) = 1[/tex]
[tex]0.5(2x) + 0.5( \frac{3}{4} ) - \frac{1}{3} (0.1) - \frac{1}{3} (x) = 1[/tex]
[tex]x + \frac{3}{8} - \frac{1}{30} - \frac{1}{3} x = 1[/tex]
Next you have to collect like terms :
[tex]x - \frac{1}{3} x + \frac{3}{8} - \frac{1}{30} = 1[/tex]
[tex] \frac{2}{3} x + \frac{41}{120} = 1[/tex]
Lastly, you can solve x :
[tex] \frac{2}{3} x = 1 - \frac{41}{120} [/tex]
[tex] \frac{2}{3} x = \frac{79}{120} [/tex]
[tex]x = \frac{79}{120} \div \frac{2}{3} [/tex]
[tex]x = \frac{79}{80} [/tex]
[tex] x = 0.9875[/tex]

Two parallelograms are similar. The base of the first is 12cm, and its height is 8 cm. Find the base of the second parallelogram if its height is 34 cm.
Answers
Answer:
The base of the second parallelogram is 51cm.
Step-by-step explanation:
If the parallelograms are similar, it means by applying the same scale factor to all the sides in one gives you the other. The question tells us the height of the first shape is 8cm and the height of the second shape is 34cm. That means the scale factor is:
[tex]\frac{34}{8}=4.25[/tex]
Apply this same scale factor to the base of the first shape to find the base of the second:

What is the volume of the pyramid?
12 in
8 in
10 in
120 in
320 in
480 in
960 in
Answers
Answer:
B. 320 inches cubed
Step-by-step explanation:
A pyramid's volume is denoted by: V = (1/3) * B * h, where B is the base area and h is the height.
Here, the base is a rectangle with dimensions 10 inches by 8 inches. The area of a rectangle is denoted by: A = lw, where l is the length and w is the width. The length is 8 and the width is 10, so plug these in:
A = lw
A = 8 * 10 = 80
So, we know that B = 80.
We are also given that the height is h = 12, so plug these values into the volume formula:
V = (1/3) * B * h
V = (1/3) * 80 * 12 = 320
The answer is thus B.

Marcus builds kites for a 14 day summer kite festival he plans to give away about the same number of kites each day he gives away 492 kites the first two days did Marcus stick to his plan?
Answers
Answer:
He did not stick to plan; he does not have enough kites.
Step-by-step explanation:
A key information is missing from the question, the number of kites that Marcus made.
After a quick web search, I have found that, in this problem, Marcus has built 2,744 kites in total.
It is know that he gave away 492 kites in the first two days, in a 14 day festival, there are 7 two-day periods. The number of kites required for Marcus to keep that same rate throughout the whole festival is:
[tex]n=\frac{14}{2}=7 \\K=7*492\\K=3,444\ kites[/tex]
Therefore, Marcus did not stick to his plan since he would have needed 3,444 kites to give kites away at the same rate as he did for the first couple days. This could also be interpreted as Marcus giving away too many kites in the first couple days.

of alien races think invading Earth is a bad idea.
What percent of alien races think invading Earth is a bad idea?
Answers
Answer: 90%
Step-by-step explanation: To write a fraction as a percent, first remember that a percent is a ratio of a number to 100.
So to write 9/10 as a percent, we need to find a fraction
equivalent to 9/10 that has a 100 in the denominator.
We can do this by setting up a proportion.
So we have [tex]\frac{9}{10} = \frac{n}{100}[/tex].
Now, we can use cross-products to find the missing value.
So we have (9)(100) which is 900 is equal to (10)(n) or 10n.
So we have 900 = 10n.
Next, dividing both sides of the equation by 10, we have 90 = n.
So, 9/10 is equal to 90/100 or 90%.
Answer:
90%
Step-by-step explanation:
9/10 times 100 is 90%

Answers
Answer:
the answer is 12 degrees
The measure of angle ACB when the secant BC and the tangent AC intersect is 12°
Secant and Tangent intersectionWhen a secant and a tangent meet outside the circle, thwe product of the length of the secant and its external segment equals the square of the length of the tangent segment.
Therefore,
arc XA = 2(64) = 128 degrees.
Hence,
m∠C = 1 / 2 (152 - 128)
m∠C = 1 / 2 (24)
m∠ACB = 12°
Therefore, angle ACB is 12 degrees.

Two ships leave the same port. Ship A travels at a constant speed of 30 km/h. Ship B travels at a constant speed of 37 km/h. The angle between their paths 62 degrees. How far apart are the two ships from eachother three hours later?
Answers
Answer:
The distance between them is 105.07 km
Step-by-step explanation:
First we need to find the distance travelled by each ship.
To find this distance, we should use the formula:
distance = speed * time
For ship A, we have:
distance1 = 30 * 3 = 90 km
For ship B, we have:
distance2 = 37 * 3 = 111 km
Now, to find the distance between the ships, we can use the law of cosines, where a, b and c are the respectively the distance travelled by ship A, the distance travelled by ship B and the distance between them:
c^2 = a^2 + b^2 - 2*a*b*cos(62)
c^2 = 90^2 + 111^2 - 2*90*111*0.4695
c^2 = 11040.39
c = 105.07 km
The distance between them is 105.07 km

Slope is calculated by [tex]\frac{y1-y2}{x1-x2}[/tex] so now you put the points (-10,4) and (-10,8) into that.
Since both x values are the same you can tell that the line is a vertial line meaning the slope is undefined.
