A polygon has 12 sides. Find the sum of its interior angles.
Answer: 1800°
Step-by-step explanation: In this problem, we're given that a polygon has 12 sides and we're asked find the sum of the measures of its interior angles.
The formula for finding the sum of the measures of the interior angles of a polygon is 180 (n - 2) where n represents the number of sides.
So here, since our polygon has 12 sides, we can plug a 12 in for the n in our formula and we have 180 (12 - 2) which is our equation.
Simplifying inside the parentheses first, 12 - 2 is 10 so we have 180 (10) which is 1800.
So if a polygon has 12 sides, then the sum of the measures of its interior angles is 1800°.

A 34 - m tall building casts a shadow. The distance from the top of the building to the tip of the shadow is 36 m . Find the length of the shadow. If necessary, round your answer to the nearest tenth.
Answer:
Length of the shadow is 11.8 meters.
Step-by-step explanation:
In the figure attached,
AB is a 34 meter tall building casting a shadow BC.
Let the measure of BC = x meters
It is given that the distance between A and C is 36 meters.
To find the length of BC we will apply Pythagoras theorem in the triangle.
AB² + BC² = AC²
(34)² + x² = (36)²
1156 + x² = 1296
x² = 1296 - 1156
x² = 140
x = √140
x = 11.832 meters
≈ 11.8 meters
Therefore, length of the shadow will be 11.8 meters.

A rectangle field with area 300 square meters has a length that is 5 meters more than it's width. If W represents the width of the field then an equation that can be used to determine the value of W is?
A) w^2-1500
B) w^2-295
C) w^2+5w-300
D) w^2-5w-300
E) 5w^2-300
The equation that would be used to determine the value of w is expressed as: C. w² + 5w - 300
What is the Area of a Rectangle?Area of a rectangle = (length)(width).
Given the following:
Area = 300 sq. mWidth = wLength = (w + 5) mTherefore, equation that would be used to find the value of w is:
(w + 5)(w) = 300
w² + 5w = 300
w² + 5w - 300

Lines A and b are parallel and lines e and f are parallel. If m<1=89, what is the measure of <5?
M<5=?
Answer:
Given the statement:
Lines a and b are parallel and lines e and f are parallel.
if [tex]m \angle 1 = 89^{\circ}[/tex]
By supplementary angles:
[tex]m\angle 1+ m\angle 2 = 180^{\circ}[/tex]
⇒[tex]89^{\circ}+ m\angle 2 = 180^{\circ}[/tex]
Subtract 89 degree from both sides we have;
[tex]m \angle 2 = 91^{\circ}[/tex]
Since,
m∠4 = m∠5 [Vertically Opposite angles] .....[1]
m∠4 = m∠3 [Alternate Interior angle] .....[2]
By [1] and [2] we have;
m∠5 =m∠3 ....[3]
Also;
m∠2 = m∠3 [Alternate interior angle] ....[4]
by [3] and [4] we have;
m∠5 = m∠2
Substitute the given values we have;
[tex]m \angle 5 = 91^{\circ}[/tex]
Therefore, the measure of [tex]m \angle 5[/tex] is, [tex]91^{\circ}[/tex]

2x + 18 = 4x - 14.
On subtracting both sides by 4x
2x -4x + 18 = -14.
- 2x + 18 = - 14 .
On subtracting both sides by 18
- 2x = - 14 -18 .
- 2x = - 32 .
On dividing both sides by -2 .
x = 16.
Therefore, x = 16.

Which number produces an irrational number when added to 2/5
The correct answer to this is that:
Any irrational number when added to 2 / 5 still produces an irrational number.
For example, if we use π to add to 2/5 or 0.4. As far as we know the decimal digits for π just go on forever and do not have a repeating cycle hence making it an irrational number. Adding a rational number such as 0.4 to the value of π does not really greatly change the value of π. The decimal digits (hundredths place and so on) of the resulting number will still go on forever without a continual repeat.
So 0.4 + π is still irrational.

Prove that there does not exist integers m and n such that 2m+4n=7
To prove that there are no integers m and n that satisfy 2m + 4n = 7, we can assume the opposite and show that it leads to a contradiction. We can rearrange the equation and analyze the parity of the terms to prove there are no integer solutions.
Explanation:To prove that there does not exist integers m and n such that 2m + 4n = 7, we can start by assuming that such integers do exist. Let's suppose m and n are integers that satisfy the equation.
Rearranging the equation, we have 2m = 7 - 4n. This means that 2m is an even number and 7 - 4n is an odd number. However, there is no way for an even number and an odd number to be equal. Therefore, our assumption was incorrect, and there are no integers m and n that satisfy the equation 2m + 4n = 7.

The directions for mixing an insect spray say to use 1 3/4 ounces of chemical in each gallon of water. How many ounces of chemical should be mixed with 4 1/5 gallons of water?
7 7/20 ounces of chemical should be mixed with 4 1/5 gallons of water.
To determine the amount of chemical to mix with 4 1/5 gallons of water, you need to use the given ratio of 1 3/4 ounces of chemical per gallon of water.
1.) Convert 4 1/5 gallons to a mixed number:
4 1/5 = 21/5 gallons.
2.) Multiply the amount of water by the chemical-to-water ratio:
(21/5) gallons * (7/4) ounces = 147/20 ounces.
3.) Convert 147/20 ounces to a mixed number:
147/20 = 7 7/20 ounces.
Therefore, 7 7/20 ounces of chemical should be mixed with 4 1/5 gallons of water.

the speed limit on a highway is 70 miles per hour about how fast is this in miles per minute
The speed of 70 miles per hour is approximately equivalent to 1.17 miles per minute. This conversion is done by dividing the speed in miles per hour by 60, the number of minutes in an hour.
Explanation:To calculate the conversion from miles per hour to miles per minute, you divide the speed in mph by 60, as there are 60 minutes in an hour. So if we are given a speed limit of 70 miles per hour, that would convert to approximately 1.17 miles per minute.
This is calculated as 70 miles per hour ÷ 60 minutes per hour = 1.17 miles per minute
It's important to remember to use the correct conversion factor related to time, in this case that there are 60 minutes in an hour, to ensure the accuracy of the conversion.

Step-by-step explanation:
You could, if you wished, take out the negative sign, obtaining -(8)(3). That would be -24.
But if you meant exponentiation, it would look like (-8)^3, or (-8)³, and that would be equal to 8*8*8 = 512.
