Solve for x in the diagram below.
Answer:
x = 20°
Step-by-step explanation:
here's your solution
=> it is given that whole angle is 90°
=> so, x + (3x + 10) = 90°
=> x + 3x + 10 = 90°
=> 4x + 10 = 90°
=>4x = 90 - 10
=> 4x = 80°
=.
=> x = 80/4
=> x = 20°
one angle is 20° and other 70°
hope it helps
Answer:
20 is your answer
x+3x+10=90 being right angle
4x=90-10
x=80/4=20

A hot air balloon went from an elevation of 5,717 feet to an elevation of 3,388
feet in 34 minutes. What was its rate of descent?
The rate of the descent was
feet per minute.
Answer:
68.5 feet per minute
Step-by-step explanation:
rate of descent = feet / minute
First you need to find how many feet it has descended:
beginning altitude- ending altitude = total feet descended
5717 feet - 3388 feet = 2329 feet
To figure out the rate of decent we will divide
2329 feet / 34 minutes = 68.5 feet per minute
The hot air ballon descended 68.5 feet per minute for 34 minutes.

Andy is wrapping gifts for the holidays. He has 3 rolls of wrapping paper that are 18- inches wide and 24- inches long. What is the total area that 3 rolls of wrapping paper could cover?
Answer:
1296 sq inches
Step-by-step explanation:
To start, you need to get the total area of each individual roll of wrapping paper. To do this, you need to multiply the length x width, which would be 18 x 24 = 432. Then, you have three rolls so you mutiply that by three, which is 432 x 3 = 1296. You add the unit, and that leaves you with 1296 sq inches.

which number is the closest approximate value for sqrt 105
Answer:
10.
Step-by-step explanation:
Lets define a square root. A square root is a number multiplied by itself. 10 x 10 = 100, this is the closest we can get to 105, therefore 10 is the answer.

Which would be the first step for solving the equation x + 2 = 18?
A. add - 2 to both sides of the equation
B. add 18 to both sides of the equation
c.
divide both sides of the equation by
7
16
D
multiply both sides of the equation by
7
Answer:
A. Add -2 to both sides
Step-by-step explanation:
The reason you need to add -2 to both sides is because if you add -2 to -2 it cancels out and you are left with x=18. But you need to add -2 to 18 too because them the equation won't be equal anymore.

find the solution to the system of equations
Answer:
(-3, -4)
Step-by-step explanation:
y= -4
so you plus y in for the y=2x+2 equation where you get x=-3
[tex]\huge\text{Hey there!}[/tex]
[tex]\large\text{If y = -4 then SUBSTITUTE it into the EQUATION}[/tex]
[tex]\large\text{-4 = 2x + 2}[/tex]
[tex]\large\text{TURN the EQUATION}[/tex]
[tex]\large\text{2x + 2 = -4}[/tex]
[tex]\large\text{SUBTRACT by 2 to BOTH SIDES}[/tex]
[tex]\large\text{2x + 2 - 2 = -4 - 2}[/tex]
[tex]\large\text{CANCEL out: 2 - 2 because that gives you 0}[/tex]
[tex]\large\text{Keep: -4 - 2 because it helps us solve for x}[/tex]

[tex]\large\text{DIVIDE by 2 to BOTH SIDES }[/tex]
[tex]\mathsf{\dfrac{2x}{2}=\dfrac{-6}{2}}[/tex]

How many roots does y=3x^2+8 have?
Answer:
This quadratic has two unequal, imaginary roots.
Step-by-step explanation:
y = 3x^2 + 8 is a quadratic function, and (like all quadratics) it has two roots. In this case they happen to be different (unequal), as well as imaginary.
Setting y = 3x^2 + 8 = 0, we get:
3x^2 = -8, or
x^2 = -8/3
Taking the square root of both sides, we get
x = ±i√(8/3) (2 imaginary roots)
The sum of the lengths of any two sides of a triangle must be greater than the third side. If a triangle has one side that is 23cm and a second side that is 4cm less than twice the third side, what are the possible lengths for the second and third sides?
Answer:
21 < x < 27
Step-by-step explanation:
Given that :
Side 1 = 23
Side 3 = x
Side 2 = 2x - 4
23 + x > 2x - 4
Collect like terms
x - 2x > - 4-23
-x > - 27
x < 27
Also ;
23 + 2x - 4 > x
23 - 4 > x - 2x
21 > - x
-21 < x
x > - 21
Hence,
Possible values of x :
x > 21 and x < 27
21 < x < 27
