Which statement is true?

A city's citizens cast ballots on whether or not to increase property taxes. There were 8 yes votes and 5 nay votes, in that order. if there were 4955 no votes,The total number of votes was 6,940.

The ratio of yes votes to no votes was 8 to 5, meaning for every 8 yes votes there were 5 no votes.

This ratio can be expressed as a fraction: 8/5.

To calculate the total number of votes, we need to know only the number of no votes, which we know is 4955.

We can then multiply this number by the fraction 8/5. This gives us a total of 6,940 votes.

Answer:

6i-4

Step-by-step explanation:

To simplify the expression 4i+(8-3i) - 12+√-25, you can start by combining like terms.

First, you can combine the terms 4i and -3i to get 1i. You can also combine the constants 8 and -12 to get -4.

So, the expression becomes 1i - 4 + √-25.

Next, you can simplify the square root. √-25 is the same as √(-25) which is the same as √(5*-5), which is the same as 5√(-1). √(-1) is equal to i, so 5√(-1) is equal to 5i.

Therefore, the final simplified form of the expression is 1i - 4 + 5i, which is equal to 6i - 4.

The time that has elapsed since Gerardo started walking away from car will be equal to 5 seconds.

We solve this problem by converting it into a linear equation that has three variables in it. Since we have distance, time and speed the three variables will be d, t and s respectively. The expression which shows the distance of Gerardo will be expressed as

d = (s×t) + 9; we have the constant as 9 because Gerardo was 9 feet away from his car.

Now, we have the distance as d = 24 feet and the speed is constant that is equal to 3 feet per second and we need time which will be

24 = (3×t) + 9

15 = 3×t

=> t = 15/3

The most sensible average to use in this case would be the mode, which is the value that appears most frequently in the data set. In this case, the mode is 2, which appears 9 times in the data set. This means that the most common number of children in a family in the class is 2.

In this case, the most sensible average to use would be the mode, which is the number that appears most frequently in the data set. This is because the mode represents the most common number of children in the families of the children in the class, which is likely to be a more accurate representation of the typical family size in the class than the mean or median.

To find the mode, we first need to count how many times each number appears in the data set. In this case, the numbers 1, 2, 3, and 4 appear in the data set as follows:

1: 7 times

2: 11 times

3: 3 times

4: 1 time

We can see that the number 2 appears most frequently, with a count of 11. Therefore, the mode in this case is 2, and this is the most sensible average to use in this situation.

In 35mm single-lens camera the images produce negative that can be used as backups instead of using a digital camera.

A single-lens reflex camera (SLR) is a type of camera that typically employs a mirror and prism system (hence the word "reflex" from the reflection of the mirror) and allows the photographer to look through the lens to preview the exact scene that will be photographed.

Most SLR cameras have a mirror that swings out of the way of the light when the shutter button is depressed, allowing light to reach the light receptor and capturing the image.

The roof pentaprism found in the optical path between the reflex mirror and viewfinder of most SLR cameras enables upright and laterally accurate vision.

A camera's manual focus adjustment or an autofocus system's automated focus adjustment are both options.

Both equations y = 0.5x + 2.75 and y – 0.5x = 2.75 are equal. Hence, these systems will have infinite solutions. Hence, Option a is the most suitable answer to this question.

The system of equations having an infinite number of solutions must be the same.

In option a -

we have, y = 0.5x + 2.75 and 2y = x + 2.75

Rewriting the second equation 2y = x + 2.75 in slope-intercept form, we get,

2y = x + 2.75

y = x/2 + 2.75/2

y = 0.5x + 1.375

Both equations are not similar.

Hence this option is not the right choice.

Similarly, we will check for option b -

we have, y = 0.5x + 2.75 and y – 0.5x = 2.75

From the second equation y - 0.5x = 2.75, this can be expressed as y = 0.5x + 2.75 in the slope-intercept form.

Here, we get both equations equal.

Thus,  y = 0.5x + 2.75 and y – 0.5x = 2.75 will have infinite solutions.

Similarly, checking for other options, we do not get any similar equations.

750 ft

Step-by-step explanation:

the 2 situations are similar ( both right triangles ) with corresponding sides being in proportion.

let h be the height of the cell phone tower

We require the dimensions to be the same, using the conversion

1 foot = 12 inches , then

10 ft = 10 × 12 = 120 in

125 ft = 125 × 12 = 1500 in

then we obtain

[tex]\frac{h}{1500}[/tex] = [tex]\frac{120}{20}[/tex] =  6 ( multiply both sides by 1500 to clear the fraction )

h = 1500 × 6 = 9000 in ( divide by 12 to convert to ft )

h = 9000 in ÷ 12 = 750 ft

that is the cell phone tower is 750 ft tall.

The given statement is true that the points on a perpendicular bisector of a line segment are equidistant from the segment’s endpoints.

A line that splits another line segment into two equal halves by intersecting it perpendicularly is known as a perpendicular bisector. A rule, compass, and pencil can be used to create a perpendicular bisector.

When two lines cross at right angles or 90 degrees, they are said to be perpendicular to one another. A line that splits a line into two equally sized parts is known as a bisector. A line segment's perpendicular bisector suggests that it meets the segment at a 90-degree angle and splits it into two equal halves.

"Perpendicular bisector theorem states that if a point is on the perpendicular bisector of a segment, then it is equidistant from the segment’s endpoints".

Answer:

0 Joules (No work)

Step-by-step explanation:

The amount of work done on an object is equal to the force applied to the object times the distance over which the force is applied. In this case, the force applied to the car is 100 newtons, but the car does not move, so the distance over which the force is applied is 0 meters.

Therefore, the amount of work done on the car is 100 newtons * 0 meters = 0 joules. This means that no energy has been transferred to or from the car as a result of the force applied to it.

Answer:

Marker = $0.50

Pencil = $0.15

Step-by-step explanation:

The cost of 3 markers and 2 pencils can be represented as 3M + 2P = $1.80.

The cost of 4 markers and 6 pencils can be represented as 4M + 6P = $2.90.

Now that we have our two equations, we can solve for M and P. To do this, we can eliminate one of the variables by multiplying one equation by a constant and adding the two equations together.

For example, if we multiply the first equation by 4 and the second equation by -3, we get:

12M + 8P = $7.20

-12M - 18P = -$8.70

Adding these two equations together, we get:

-10P = -$1.50

Dividing both sides by -10, we get:

P = $0.15

Now that we have found the value of P, we can substitute it back into one of our original equations to find the value of M. If we substitute P = $0.15 into the first equation, we get:

3M + 2($0.15) = $1.80

3M + $0.30 = $1.80

3M = $1.50

M = $0.50

So, the cost of 1 marker is $0.50, and the cost of 1 pencil is $0.15.
