Answer:
30.96° to the nearest hundredth
Step-by-step explanation:
Let x = angle of elevation
tan x = 60/100 = .6
x = arctan .6
x ≅ 30.96°
Find the equation of a line perpendicular to x = -4 that contains the point (-3, 4). Write the equation in slope-intercepi
form.
I NEED HELP ASAP Catherine finds that in a randomly selected sample of 500 families in her home town, 45% own at least one computer. Her research shows that there are a total of 35,000 families in her town.
Which statements are true?
Select each correct answer.
To estimate the percentage well, she would need to collect data for all 35,000 families.
Since her sample was randomly selected, she can reasonably infer that about 45% of the 35,000 families in her town own at least one computer.
If she collected data for a random sample of 1000 families in her home town, then that percentage would be a better estimate for the percentage of all 35,000 families that own a computer.
Since her sample was only 500 families, it is not possible that the percentage is a good estimate for the percentage of all 35,000 families that own a computer.

Review: Jen sells flowers. She charges $2 per flower plug a $3 flat delivery fee. How many flowers did she deliver if she made $21?
Answer:
she delivers 9 flower plugs.
Step-by-step explanation:
in a standard equation the equation would be 21 = 2x + 3 and if you isolate the x you would have to first subtract the 3 from both sides and that would leave you with 18 = 2x and then you have to divide both sides by 2 and get 9=x

A club is going to raise money by printing calendars with photos of the community. The cost of printing the calendars is $5.50 per calendar. The photographer also charges a one-time cost of $200 for taking the photos. The club has $1500 to cover the initial costs of the calendar. Create an equation that represents the number of calendars the club can print. Use the variable n for the number of calendars
Answer:
[tex]n = \frac{1300}{5.50}[/tex]
[tex]n = 236[/tex]
Step-by-step explanation:
Given
The cost of printing one calendars [tex]= 5.5[/tex] dollars
The one time charge of taking photo [tex]= 200[/tex] dollars
The total sum of money with the club [tex]= 1500[/tex] dollars
The total sum of money going into printing of calendars [tex]= 1500 -200 = 1300[/tex] dollars
The total number of calendars that can be printed with remaining [tex]1300[/tex] dollars is equal to
[tex]n = \frac{1300}{5.50}[/tex]
[tex]n = 236[/tex]

. Find all values of x that will make ∠A an obtuse angle given
m∠A = 12x - 6
Answer:
(8, 15]
Step-by-step explanation:
If ∠A is bigger than 90 then that means 12x-6 > 90
12x > 96
x > 8
and we know that the angle must be between 0 and 180. so 12x < 186
x <= 15
. sells t-shirts for $2 and shorts for $4 in April the total sales were 600.00 people bought four times as many t-shirts as shorts how many t-shirts and shorts did they sell?
Answer:
200 t-shirts and 50 shorts
Step-by-step explanation:
t= t-shirts
s = shorts
600 = 2t + 4s
t = 4s
600 = 2(4s) + 4s
600 = 8s + 4s ––––> 600 = 12s
s = 50
t = 4(50) –––––> t = 200
check:
600 = 2(200) + 4(50)
600 = 400 + 200
600 = 600

Answer:
A
Step-by-step explanation:
To move something up or down, it means we're moving along the y-axis. So we need to change the y-coordinate.
To move it up, we'll be moving towards the positive end of the y-axis. On a coordinate plane, if you move anything "up," you're moving closer to the positive end of the y-axis.
To move it five units up, we need to move 5 units positively.
So our y is:
y + 5
To move something left or right, it means we're moving it along the x-axis. So we need to change the x-coordinate.
To move it left, we'll be moving it towards the negative end of the x-axis. Think about it: on a basic number line (which is what the x-axis is), the more you move towards the left, you move closer to 0, and therefore the negative end.
To move it 2 units left, we need to move 2 units negatively.
So our x is:
x - 2
Putting them together, we have:
(x, y)
(x - 2, y + 5)

What is the value of x?
Step-by-step explanation:
Given in the picture that,
2x + 2x + 2x + 2x + 2x = 11
So, by the problem,
=> 2x + 2x + 2x + 2x + 2x = 11
=> 10x = 11
[tex] => x = \frac{11}{10} or \: 1.1(ans)[/tex]
Hence required value of x is 1.1 (Ans)

One last time why dont we.
This time we are given a cylinder to find the area of which is pretty fun ngl.
Lets take a look at the formula for a cylinder :
Volume = [tex]\pi[/tex] x r² x h
Now this may look weird cause that house thing is for sure not a number but trust me it is easy once you know what you're looking at.
So that house thing is called pi, and really it is worth 3.14 just it looks like that for some reason. But it is used to find the area of circles.
So what we are going to do is find the area of the circle which is the base of the cylinder and multiply it by the height to find the total area.
Again lets see what we are given :
Radius = 8
Height = 15
Now we plug this into the formula :
Volume = [tex]\pi[/tex] x r² x h
Volume = [tex]\pi[/tex] x 8² x 15
(don't forget your little 2 after the radius (8))
So first lets do pi x 8²
=
Which gives us roughly around 201
So now we have the surface area of the base circle of this cylinder, all we have to do is multiply by the height.
So :
201 x 15
=
3015³
(don't forget your little 3 cause its 3D)
But that is your answer.
I hope this helps!

Starlin's goal is to spend less than $415 on a trip. So far, he has spent $25 on gas for his car. He will spend $100 each day on other expenses.
Let d represent the number of days for Starlin's trip.
Starlin's trip must last fewer than __ days.
Answer
Less than or equal to 4 days.
Step-by-step explanation:
Let D represent the number of days for Starlin's trip. We know that Starlin has spent $25 on gas and will spend $100 for each day. So use the equation d=25+100d < 415. (We also know that Starlin plans on spending less than $415 on the trip, so if anything is above $415, we know it is the wrong answer.) Subtract 25 on both sides and then divide by 100; the equation should go like this:
25 + 100d < 415
25 + 100d - 25 < 415 - 25
100d < 390
d < 3.9
It would be wise to round to 4 unless otherwise specified.

Supplementary angles add up to 180°∠EGF and ∠FGBQ6
Vertical angles formed by two intersecting lines and are opposite to each other∠EGF and ∠BGCQ7
Adjacent angles share a common side∠AGB and ∠BGCQ8
Complementary angles form a 90° angle∠BGC and ∠CGDQ9
Measure of ∠CGD
∠CGD is complementary with ∠BGC and
∠BGC is vertical with ∠EGF, which is 35°
m∠CGD = 90° - 35° = 55°
