Answer:
x = 35
Step-by-step explanation:
The figure has 6 angles so the figure is a convex hexagon
The sum of interior angles in a convex hexagon is equal to 720
4x - 5 + 117 + 3x - 3 + 3x + 6 + 118 + 4x -3 = 720 add like terms
14x + 230 = 720 subtract 230 from both sides
14x = 490 divide both sides by 14
x = 35

The line becomes steeper.
The line becomes less steep.
The line moves higher.
The line moves lower.
Answer:
The lines moves lower.
Step-by-step explanation:
The steepness of a line is related to the slope, m.
b is the y-intercept, not the slope.
b is where the line intersects the y-axis.
Changing b changes the vertical position of the line.
Answer: The lines moves lower.

What is the zero of
q(x) = -7/3x + 14?
Answer:
x = 6
Step-by-step explanation:
Solve for x:
-(7 x)/3 + 14 = 0
Put each term in -(7 x)/3 + 14 over the common denominator 3: -(7 x)/3 + 14 = -(7 x)/3 + 42/3:
(-(7 x)/3 + 42/3) = 0
-(7 x)/3 + 42/3 = (-7 x + 42)/3:
((-7 x + 42)/3) = 0
Multiply both sides of (-7 x + 42)/3 = 0 by 3:
(3 (-7 x + 42))/3 = 3×0
(3 (-7 x + 42))/3 = 3/3×(-7 x + 42) = -7 x + 42:
(-7 x + 42) = 3×0
0×3 = 0:
-7 x + 42 = 0
Subtract 42 from both sides:
(42 - 42) - 7 x = -42
42 - 42 = 0:
-7 x = -42
Divide both sides of -7 x = -42 by -7:
(-7 x)/(-7) = (-42)/(-7)
(-7)/(-7) = 1:
x = (-42)/(-7)
The gcd of 42 and -7 is 7, so (-42)/(-7) = (-(7×6))/(7 (-1)) = 7/7×(-6)/(-1) = (-6)/(-1):
x = (-6)/(-1)
(-6)/(-1) = (-1)/(-1)×6 = 6:
Answer: x = 6

1. A water balloon is launched in the air from a height of 12 feet and reaches a maximum height of 37 feet after 1.25 seconds. Write an equation to represent the height h of the water balloon at time t seconds. what is the height of the balloon at 2 seconds?
Answer:
28feet
Step-by-step explanation:
The height of the balloon is given as h(t) = -16t² + 40t + 12 at 2 seconds, the height is 28 feet
the pathway of sams dive into the swimming pool can be represented by the equation h=-16t²+15t+12 (where t=time in seconds and h = height in feet). what is sam's height after 2 seconds?
Given the equation representing the pathway of sam's dive into the swimming pool, his height after two seconds is -22ft.
What is a Quadratic Equation?Quadratic equation is simply an algebraic expression of the second degree in x. Quadratic equation in its standard form is;
ax² + bx + c = 0
Where x is the unknown
Given the data in the question
Equation of the pathway of sams dive into the swimming pool is h = -16t² + 15t + 12.Time t = 2.0 secondsHeight h = ?Now, to get the height after 2 seconds, we substitute 2 for t in the equation.
h = -16t² + 15t + 12.
If t = 2
h = -16(2)² + 15(2) + 12
h = -16(4) + 30 + 12
h = -64 + 30 + 12
h = -64 + 42
h = -22ft
Therefore, given the equation representing the pathway of sam's dive into the swimming pool, his height after two seconds is -22ft.

The maximum load that a cylindrical column with a circular cross section
can hold varies directly as the fourth power of the diameter and
inversely as the square of the height. A 9 meter column 2 meters in
diameter will support 64 metric tons. How many metric tons can be
supported by a column 9 meters high and 3 meters in diameter?
Answer:
2396
Step-by-step explanation:
Let the diameter = d
Let the height = h
Formula
Metric Tons = k * d^4 / h^2
Solution
Metric Tons = 64
d = 2
h = 9
k = ?
(You can't do the second part by not using a ratio unless you put k in and solve for it)
64 = 2^4 k / 9^2
64 = 8 *k / 81
64 * 81 / 8 = k
5184 / 8 = k
k = 648
Solve for the second example
Metric Tons = d^4 * k / h^2
Metric Tons = ?
d = 5
h = 13
k = 648
Metric Tons = 5^4 * 648 / 13^2
Metric Tons = 625 * 648 / 169
Metric Tons = 2396 rounded.

Under his cell phone plan, Ryan pays a flat cost of $68.50 per month and $5 per gigabyte. He wants to keep his bill at $92.50 per month. How many gigabytes of data can he use while staying within his budget?
Answer:
answer is 5.7
Step-by-step explanation:
Under Ryan's cell phone plan, he pays a flat cost of $68.50 per month and $5 per gigabyte. With a budget of $92.50, he can use up to 4 gigabytes of data.
Use the concept of subtraction defined as:
Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.
Given that,
Ryan's flat cost per month is $68.50.
He pays $5 per gigabyte of data.
Ryan wants to keep his bill at $92.50 per month.
We know that Ryan pays a flat cost of $68.50 per month,
so subtract that from his budget:
$92.50 - $68.50 = $24.
Since Ryan pays $5 per gigabyte,
Divide the remaining budget ($24) by the cost per gigabyte ($5) to find out how many gigabytes he can use:
$24 / $5 = 4.8 gigabytes.
Therefore,
Ryan can use up to 4.8 gigabytes of data and still stay within his budget. Keep in mind that any fraction of a gigabyte will be rounded down,
So he can use a maximum of 4 gigabytes.
