Explanation: The bottom left angle is 90 degrees because of the symbol. ( Make sure you know this for future problems.) The whole triangle needs to add up to 180. This isn’t the right way to solve this kind of problem but I know how to solve it using this way and I know the at 10 is the right answer. The other two angles need to add up to 90 because 90 + 90 = 180. So basically I just substituted the same number into x until I added both outcomes and got 90. I hope you understand that cause I don’t really know how to explain it well. Let me try and show you.
3(x)+5 6(x)-5
Now you have to plug in the same number for x until both numbers add to ninety.
3(5)+5 6(5)-5.
( 5 isn’t the right number for x this is just an example. )
You end up with 20 for the first one, and 25 for the second one. 20 + 25 = 45 and 90 + 45 is only 135. So this means that 5 isn’t the right answer and you need to substitute a higher number in for x.
3(10)+5 6(10)-5
( This is the right setup. )
You end up with 35 for the first one and 55 for the second one after you distribute and solve. Now you have 35 and 55. 35 + 55 = 90 and 90 + 90 = 180. This is how you know that you are right. I hope this helps. :)

Well first we got to convert yards and feet into inches.
21 feet=252 inches
11 yards=396 inches
Alright so now that we have the inches needed we must find the cost for both Emily and Andy’s needed wire.
Emily:
We know how much it would cost for 200 inches, which is 8$.
15 inches adds a .60$ increase, which means that 5 inches is equivalent to .20$. By adding that to .60$ we get .80$ or the amount it would cost for 20 inches. We now know how much it would cost for 40 inches, 1.60$.
8+1.60=9.60 or how much it costs for 240 inches.
If it costs .80$ for 20 inches that means it costs .40$ for 10 inches.
9.60+.40=10
To find how much it costs for 2 inches we divide .40 by 5 which is .08.
10+.08=10.08$
Emily will spend 10.08$ for her needed wire.
Andy:
We know how much it would cost for 300 inches, which is 12$.
We also know how much it costs for 20 inches, which is .80$. So we multiply that by 4 to get how much it would cost for 80 inches.
.80*4=3.20
We then add that to the cost of 300 inches.
12+3.20=15.20
We know how much it would cost for 10 inches, which is .40$.
So we add that to the amount it would cost for 380 inches.
15.20+.40=15.60
Finally we know how much it costs for 2 inches, which is .08$. So we multiply that by 3 to find how much it costs for 6 inches.
.08*3=.24
We then add that to how much it would cost for 390 inches.
15.60+.24=15.84$
Andy will spend 15.84$ for his needed wire.
Answer:
Emily pays 10.40 and Andy pays 8 dollars
Step-by-step explanation:
So let's start with Emily, she need 21 feet of wire, so we convert this to inches so; [tex]1foot=12inches\\ 21feet=(12inches)*21=252inches[/tex] but it's not listed on the tableSo we try to find the closest approximation to 252 inches which we get by adding 100 inches and 160 inches to get 260 inchesSo Emily will pay the cost of those to lengths so 100 inches cost 4.00 dollars and 160 inches costs 6.40 dollarsso she pays 4.00+6.40=10.40 dollarsNow for Andy we do much the same and find the inches in 11 yards[tex]1 yard=36inches\\ 11yards=(36inches)*11=396inches[/tex] this is also not listedSo we get the closest approximation, which is 4 of the 100 inch wires, so we get 400 inches costing 4*4.00=8 dollarsMay you please help me on this question ill give out braily

If you travel 2.2 miles in 30 minutes. How many miles did you travel in 12 minutes?
Answers
Let m = miles traveled in 12 minutes.
2.2/m = 30/12
Cross-multiply here.
30m = (2.2)(12)
30m = 26.4
m = 26.4 ÷ 30
m = 0.88
In 12 minutes, 0.88 miles is traveled.

A new sidewalk will be 4 feet wide, 240 feet long, and filled to a depth of 9 inches (0.75 foot) with concrete. How many cubic yards of concrete are needed?
Answers
Answer: The number of cubic yards of concrete that are needed is 720.
Step-by-step explanation: The same formula for this type of shape stays the same: l*w*(h or d).
240 * 4 = 960
960 * 0.75 = 720
The amount of cubic yard of concrete needed is about 720 cubic foot
How to calculate the volume of box?The formula for calculating the volume of the concrete is expressed as:
V = lwh
l is the length =240feet
w is the width = 4 feet
h is the depth = 0.75foot'
Determine the volume
V = 240 * 4 * 0.75
V = 720 cubic feet
Hence the amount of cubic yard of concrete needed is about 720 cubic foot

Please help 15 points available! What is the equation of the line that is perpendicular to y - 3 x = 2 and that passes through (6,1)?
y = 1/3x - 1
y = 1/3x + 3
y = -1/3x + 3
y = -1/3x - 1
Answers
Answer:
C) y = -1/3x + 3
Step-by-step explanation:
y - 3x = 2
+ 3x + 3x
y = 3x + 2
find the reciprocal of the slope (3) which is -1/3 so -1/3 will be the slope for the perpendicular line
y = (-1/3)x + b
now find the y-intercept (b)
(6,1) x = 6 y = 1
y = (-1/3)x + b
1 = (-1/3)6 + b
1 = -2 + b
+2 +2
3 = b

Answer:

Step one:
given that the expression for the company's average production is
[tex]P(t) = (150t) / (3t+20)[/tex]
Required:
t, when P=30
Step two:
substituting we have
30=150t/3t+20
cross multiply we have
30(3t+20)=150t
90t+600=150t
collect like terms
600=150t-90t
600=60t
divide through by 60
t=600/60
t=10 days
it will take the company 10 days
