tan22° + tan23° tan22°. tan23° = 1 prove that
Answer:
Formula:(from trigonometry)
Tan(A+B)=(tanA+tanB)/(1-tanA*tanB)
Let A=22 degrees,B=23 degrees
Tan(22+23)=(tan22+tan23)/(1-tan22*tan23)
From trigonometry we know tan45=1
Therefore tan(45)=1=(tan22+tan23)/(1-tan22tan23)
=> 1-tan22tan23=tan22+tan23
=> tan22+tan23+tan23tan22 =1
Hence proved
2x^2-11x + 5.o-x^2 + 4x +371 =0

The expression that models this situation is 45 minus two-thirds h. What was Sierra's profit if the shop was closed for 6 hours? $24 $36 $41 $49
Answer:
the profit in the case when the shop is closed for 6 hours is $41
Step-by-step explanation:
The computation of the profit in the case when the shop is closed for 6 hours is shown below:
= Expression of the situation × number of hours in which the shop is closed
= 45 - 2 ÷ 3 × 6 hours
= $41
hence, the profit in the case when the shop is closed for 6 hours is $41
Therefore the third option is correct

Given (x+1)2=9, solve for x
Answer:
x= 7/2
2(x+1)=9
x+1=9/2
x=9/2 - 1
x=7/2
Answer:
x=7/2 x=3.5
Step-by-step explanation:
divide both sides by 2
(x+1)(2)/2=9/2
simplify
x+1=9/2
subtract 1 from both sides
x+1-1=9/2-1
simplify
x=7/2

Two trains have to travel a distance of 300 miles. Train A goes at the speed of 50 mph and Train B goes at the speed of 60 mph. However, Train B leaves 1 hour later than Train A. When will the 2 trains meet?
Answer:
Both trains would meet in 6 hours time.
Step-by-step explanation:
Train A = 50 miles per hour
Train B = 60 miles per hour
Train B leaves 1 hour later than Train A: This means Train A started the journey first.
When will the 2 trains meet?
Both trains would meet when they both cover equal distance.
Distance = Speed * Time
First Hour
Train A = 50 miles
Train B = 0 miles
Second Hour
Train A = 100 miles
Train B = 60 miles
Third Hour
Train A = 150 miles
Train B = 120 miles
Fourth Hour
Train A = 200 miles
Train B = 180 miles
Fifth Hour
Train A = 250 miles
Train B = 240 miles
Sixth Hour
Train A = 300 miles
Train B = 300 miles
Both trains would meet in 6 hours time.
if x + 12 = 25. What is the value of 8x - 30?
Answer:
The value of 8x - 30 is 74 when solved.
Step-by-step explanation:
Subtract 12 on both sides to get 13 as your x value. Plug in 12 on the x value of 8x to get 104 when multiplied. Subtract 30 to get 74 as your result.
Slope of line a is ½. What is the equation of a line that is parallel to line a? Y+½x=2 -2x+y+2=0 2x-2=y -½x+y-2=0
Answer:
The equation of a line that is parallel to line a is y=½x + 2, or what is the same -½x+y-2=0
Step-by-step explanation:
A line is a polynomial function of the first degree that has the following form:
y = m * x + b
where m is the slope of the line and b is the intercept with the Y axis. The slope is the inclination of the line with respect to the abscissa axis.
In this case you know that the slope of line a is ½.
Parallel lines are two or more lines in a plane that never intersect. Two lines are parallel if they have the same slope and different y-intercepts.
You have:
y+½x=2 → y= -½x +2-2x+y+2=0 → y=2x -22x-2=y -½x+y-2=0 → y=½x + 2The line that has the same slope as line a is the last one, so the equation of a line that is parallel to line a is y=½x + 2, or what is the same -½x+y-2=0
Assume you know that a hot-air balloon is currently inflated with a certain amount of air and that the amount is a percent of the total amount required to inflate the balloon. Explain how you would determine the total amount of air required to inflate the balloon.
Answer:
Percent air is calculated as:
Percent air = Current amount/Total amount *100Solve for total amount of air:
Total amount = Current amount / Percent air * 100Substitute the values in hand to get the answer

IS THIS RIGHT? PLS HELP!
Answer:
no
Step-by-step explanation:
Can you solve this by explaining.
Answer:
The answer is 1
Step-by-step explanation:
Start by solving the division part of the equation. In order to do that, you have to flip the fraction (reciprocal) and switch from division to multiplication, thus getting 3 x 3 = 9. Now you have 9 – 9 + 1, and from there you can simply work from left to right and get your final answer: 1.
Susan got 72 marks in English out of 120 and 70 marks in
Hindi out of 150. The maximum marks in the mathematics
paper were 180. If she got 60% marks in all the three papers
how y marks did she get in mathematics?
Answer:
let the marks obtained in maths be x
total marks obtained by susan=142+x
then
A/Q
60%of 450 =(142+x)
270=142+x
x=270-142
x=128
hence marks obtained in maths=128
OR
Max marks 120+150+180=450
60% of 450 is 270
70 +72+x=270
x=270-142
x=128

use the function y=3/2x+3 to complete the table of values
Answer:
Please check the explanation.
Step-by-step explanation:
Given the function
Putting all the values of y=9, 6, 0, and -3 to complete the table
FOR y=9
putting y=9
switch sides
subtract 3 from both sides
Hence,
when y=9, x=4
FOR y=6
putting y=6
switch sides
subtract 3 from both sides
Hence,
when y=6, x=2
FOR y=0
putting y=0
switch sides
subtract 3 from both sides
Hence,
when y=0, x=-2
FOR y=-3
putting y=-3
switch sides
subtract 3 from both sides
Hence,
when y=-3, x=-4
Hence, the table becomes:
x y
9 4
6 2
0 -2
-3 -4
