The perimeter of a church window is 80 inches. If the window is in the shape of a square.what is the length of each side of the window?
The length of each side of the church window is 20 inches.
Explanation:To find the length of each side, we need to determine the perimeter of the square. The perimeter is the sum of all four sides of the square. In this case, it is given that the perimeter is 80 inches. Since all sides of a square are equal in length, we can divide the perimeter by 4 to find the length of each side. So, each side of the church window will be 80 inches divided by 4, which is 20 inches.

Astronomers measure large distances in light-years. One light-year is the distance that light can travel in one year, or approximately 5,880,000,000,000 miles. Suppose a star is 13.6 light-years from Earth. In scientific notation, how many miles away is it?
Answer:
The distance traveled in 13.6 light year is [tex]7.9968\times 10^{13}\text{ miles}[/tex]
Step-by-step explanation:
Given : Astronomers measure large distances in light-years. One light-year is the distance that light can travel in one year, or approximately 5,880,000,000,000 miles. Suppose a star is 13.6 light-years from Earth.
To find : In scientific notation, how many miles away is it?
Solution :
According to question,
The distance can travel in 1 light year is
[tex]1 \text{ light year} = 5,880,000,000,000 \text{ miles}[/tex]
We have to find the distance traveled in 13.6 light-years.
[tex]13.6 \text{ light year} =13.6\times 5,880,000,000,000 \text{ miles}[/tex]
[tex]13.6 \text{ light year} =79,968,000,000,000 \text{ miles}[/tex]
In scientific notation,
[tex]13.6 \text{ light year} =7.9968\times 10^{13}\text{ miles}[/tex]
Therefore, The distance traveled in 13.6 light year is [tex]7.9968\times 10^{13}\text{ miles}[/tex]

What is y-10=9(x+8) written in standard form?
Answer:
-9x+y=82
Step-by-step explanation:
hope this helped!
The equation y-10=9(x+8) can be transformed into standard form by distributing, simplifying, and rearranging terms to get 9x - y = -82.
Explanation:The given equation is y-10=9(x+8), and we're asked to change this slope-intercept form into the standard form. First, we'll start by distributing the 9 to both x and 8 which will result in y-10 = 9x + 72. Then, we'll bring terms involving x and y to one side of the equation, leading to -9x + y = 82. This is almost in standard form, but typically we want the leading coefficient (the coefficient of x) to be positive, so we'll multiply the equation by -1. This gives us 9x - y = -82, which is the equation in standard form.

What is the unit rate for 4543.08 km in 52.4 h? Enter your answer, as a decimal, in the box. km/h
Final answer:
The unit rate, or average speed, for traveling 4543.08 km in 52.4 hours is calculated by dividing the distance by the time, resulting in an average speed of 86.70 km/h.
Explanation:
The question asks for the unit rate of 4543.08 km traveled in 52.4 hours, which is essentially asking for the average speed in kilometers per hour (km/h). To find this, you would divide the total distance traveled by the total time taken.
Mathematically, this is expressed as:
Distance (km) / Time (h) = Speed (km/h)Substituting the given values:
4543.08 km / 52.4 h = 86.70 km/hTherefore, the unit rate or average speed is 86.70 km/h. It's important to note that when calculating such problems, it's essential to maintain consistency in the units (in this case, km for distance and hours for time) to ensure the accuracy of your result.
Which step could be used to solve x + 3.6 = -1.7 for x in one step? Check all that apply.
[ ] add 3.6 to both sides
[ ] add -3.6 to both sides
[ ] add 1.7 to both sides
[ ] add -1.7 to both sides
[ ] subtract 3.6 from both sides
[ ] subtract 1.7 from both sides
Answer: Option (2) and (5) are the correct options.
Step-by-step explanation:
Since, the given expression, x+3.6= -1.7
If we add -3.6 in both sides then we get x+3.6+(-3.6)=1.7-3.6⇒x= -1.9
while,
If we subtract 3.6 from both sides then we get x+3.6-3.6=1.7-3.6⇒x= -1.9
Thus, In the above by adding -3.6 and by subtracting 3.6 we get the value of x in one step.(because after this only x remains in LHS of the given expression)
Therefore, Option (2) and (5) are correct.
Note: Except these two options we can not get x in one step. (we can not get single x in LHS of the given expression by the other options.)

The number of cases of a new disease can be modeled by the quadratic regression equation y = –2x2 + 36x + 6, where x represents the year.
Which is the best prediction for the number of new cases in year 15?
A. 194
B. 96
C. 328
D. 614
Answer: B 96
Step-by-step explanation:
By evaluating the function in x = 15, we will see that in the year 15 there will be 96 cases.
Which is the best prediction for the number of new cases in year 15?
The function that predicts the number of cases in the year x is given by:
[tex]y = -2x^2 + 36x + 6[/tex]
So we just need to evaluate that function in x = 15, this means replacing x by 15.
[tex]y = -2*15^2 + 36*15 + 6 = 96[/tex]
So we can expect that in the year 15, there will be around 96 cases. Then the correct option is B.
