The perimeter of the polygon is 27.4 centimeters. Write and solve an equation to find the unknown side length.
Answers
Answer:
x = 7.1
Step-by-step explanation:
6.3 + 5.6 + 8.4 + x = 27.4
20.3 + x = 27.4
20.3 - 20.3 + x = 27.4 - 20.3
x = 27.4 - 20.3
x = 7.1
6.3 + 5.6 + 8.4 + 7.1 = 27.4

Answer:
x=6
Step-by-step explanation:
write the equation as 10x+5=65 then Move all terms that don't contain x to the right side and solve. and you would get 6.
Answer:
x=6
Step-by-step explanation:
Towards the bottom, you see the 65 degrees? (Sorry I'm having trouble explaining -_-) Ok, well 10x is 10 times x, and if x=6, then 10x would be equal to 60. 60+5 is 65. Therefore x=6.

The length of the side opposite the 90 degree angle of a 30-60-90 is 18 ft. Determine the lengths of the other two sides.
Round your answer to the nearest hundredth when necessary.
- The side opposite the 30 degree angle is ___ ft.
- The side opposite the 60 degree angle is ___ ft.
Answers
Answer:
The side opposite 30 is 9 ft.
The side opposite 60 is 15.59 ft.
Step-by-step explanation:
Below are pictures of how I got the answer.
I will provide steps to accompany each corresponding picture to further explain what I am doing.
1. This picture simply illustrates what the triangle looks like. The Hypotenuse is 18, as described in the problem.
2. I am showing how the sin will work. What is the opposite side and what is the hypotenuse. I picked this particular angle because it allow me to divide it by a number I already have, 18. I show that sin of 30 is 0.5
3. Now, we know what the side value is, 9. We can easily find the remaining side using Pythagorean theorem.
9^2 + y^2 =18^2
81 + y^2 = 324
y^2 = 243
y = 15.59

The ratio of ducks to ducklings at a park is 7:4. If there are 350 ducks, how many ducklings are there
Answers
Answer:
200 duckings (350:200)
Step-by-step explanation:
7:4 and 350:x
350/7 = 50
40 times 50 = 200
350:200
Plus, 350/50 = 7
200/50 = 7
The solution is, 200 ducklings (350:200) ducklings are there.
What is ratio?The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.
here, we have,
given that,
The ratio of ducks to ducklings at a park is 7:4.
If there are 350 ducks,
let , x ducklings are there
so, we get,
7:4 and 350:x
now,
350/7 = 50
and,
40 times 50 = 200
so, we have,
350:200
Plus, 350/50 = 7
200/50 = 7
Hence, The solution is, 200 ducklings (350:200) ducklings are there.

Your parents allow you to borrow a car to get to your part-time job, but you have to pay for a tank of gas each month. Gasoline costs $2.56/gallon and the tank
takes 15 gallons
You have a friend who works with you and is willing to split the cost of a tank of gas. How much do you each pay?
$ your answer goes here person
Answers
Answer:
you each pay $19.2 I hope this helps you
The amount that you save each month is half of the total tank value, $20.70.
What is mean by Fraction?A fraction is a part of whole number, and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called fraction. It can be written as the form of p : q, which is equivalent to p / q.
Since, We know that a gallon of gasoline costs $2.56,
And, the tank holds 15 gallons.
Then to fill the tank, you need to pay:
= 15 × $2.76
= $41.40
Now, you have two friends, and each of the friends pays one-quarter of a full tank per month, then you only pay a fraction of the total, which would be one-half.
($41.40)/2 = $20.70
The amount that you save is:
S = $41.40 - $20.70
S = $20.70
So, the correct answer is, $20.70

A graph titled Monthly Sales and Advertising Costs has Advertising Costs (1,000 dollars) on the x-axis and sales (1,000 dollars) on the y-axis. A line goes through points (6.4, 117) and (6.6, 120). The slope of the trend line is 15. What does that mean in regard to the data of the scatterplot? Check all that apply. The slope represents the rate of change of the data. Advertising costs increase $15,000 as sales increase by $1,000. Sales increase $15,000 as ads increase by $1,000. A positive slope infers a negative correlation.

The slope represents the rate of change of the data. Sales increase $15,000 as ads increase by $1,000.A positive slope infers a positive correlation.What can be inferred from the graph on Monthly sales?In a linear model, the slope is used to depict the change in the value of y as a result of a change in x. If this slope is positive, then there is a positive relationship between the y and x values.
In this scenario, the slope is positive which shows that there is a positive relationship between sales and advertisements such that they both increase together.

Answers
First you want to subtract the candy amount 4.55 from the total 20.35 that way we can get the total for the 5 tickets by themselves
20.35-4.55= 15.80
Then you want to divide the total for all five tickets by 5 which will get us the total for one ticket
15.80/5=3.16
