Answer:
x = 30
Step-by-step explanation:
The sum of the 3 interior angles of a triangle = 180°, hence
x + x + 10 + 3x + 20 = 180
5x + 30 = 180 ( subtract 30 from both sides )
5x = 150 ( divide both sides by 5 )
x = 30

Explain how to find the missing exponent given the base and the value
Answer:
To find the value of missing exponent, we have to split the number which is in other side of equal sign (which is not having power) as the multiple of base of the missing exponent.
On both sides, powers have the same base, so their exponents must be equal.
Step-by-step explanation:
Problem 1:Write the missing exponent:
25=5^x
Let x be the missing exponent.
To find the value missing exponent, we have to split the number which is in the left side as the multiple of the base of the missing exponent.
That is,
25=5*5 or 5^2
Now,
5^2=5^x
Powers have the same base so their exponent must be equal.
Hence the missing exponent is 2

what is the area of the polygon given below?
Answer:
C 340 square units
Step-by-step explanation:
Divide it into smallest pieces.
I see two rectangles that I'm going to do.
The long rectangle reading the paper from bottom to top is a 4 by (4+11+4) rectangle.
The wide rectangle reading the paper from left to right is a 24 by 11 rectangle.
We need to find the area of both of these rectangles and then just add them together to get the total area.
So first rectangle has area 4(19)=76 and the second rectangle has area 264. The sum of these two numbers are 340 square units.
Hello There!
The answer would be 340 square units
First, let's find the area of our small rectangle located to the left. The formula for a rectangle is width*height so we would multiply19 because we know that on our right rectangle the height is 11 and we would add 4 to that and add another 4 to that to get our length of our rectangle on the left.
Next, we multiply 24 by 11 because we are using our same formula for the rectangle on the right and once we multiply, we get a product of 264.
Finally, we add 264 and our area of the rectangle on the right together and get a sum of 340 square units.

Answer:
C. 0.36
Step-by-step explanation:
There is already a 45% chance of having oil on the land.
The oil kit has an 80% accuracy rate.
Therefore the kit has an 80% chance, of that 45% chance, of detecting oil. (Assume the owners in the area are correct in their 45% assumption)
This can be expressed as 80%*40% or 0.8*0.45

Answer:
C. [tex]\{y|y\ge 1\}.[/tex]
Step-by-step explanation:
Consider the parent function [tex]f(x)=\sqrt{x}.[/tex]
The domain of this function is [tex]x\ge 0;[/tex]The range of this function is [tex]y\ge 0.[/tex]Now consider given function [tex]h(x)=\sqrt{x+4}+1[/tex] (translated 4 units left and 1 unit up.)
The domain of this function is [tex]x\ge -4;[/tex]The range of this function is [tex]y\ge 1.[/tex]Answer:
The range of the function h(x) is [tex]R=\{y|y\geq 1\}[/tex]
Step-by-step explanation:
Given : The graph of [tex]y=\sqrt{x}[/tex] is translated 4 units left and 1 unit up to create the function h(x).
To find : What is the range of h(x)?
Solution :
When the graph f(x) is translated then
1) f(x)+b shifts the function b units upward.
2) f(x + b) shifts the function b units to the left.
The graph of [tex]y=\sqrt{x}[/tex] is translated 4 units left.
i.e. [tex]y=\sqrt{x+4}[/tex]
The graph of [tex]y=\sqrt{x}[/tex] is translated 1 unit up.
i.e. [tex]y=\sqrt{x+4}+1[/tex]
So, The required function h(x) is [tex]h(x)=\sqrt{x+4}+1[/tex]
The range of a function is set of output values produce by a function.
In the given graph, y value is always greater than and equal to 1.
So, The range of the function h(x) is [tex]R=\{y|y\geq 1\}[/tex]

By adding the system of equations and solving for x, then substantifying back into the first equation, we find that y in this system of equations is approximately 3.5556.
Explanation:To find the value of y in the given system of equations, you can add the two equations together. The first equation is x+3y=1 and the second equation is 2x – 3y = -30. Here are the steps:
Add the two equations: (x + 3y) + (2x - 3y).The y terms cancel out and you end up with 3x = -29.Divide both sides by 3 to solve for x: x = -29/3 which is about -9.6667.Substitute x = -9.6667 into the first equation: -9.6667 + 3y = 1.Isolate y by adding 9.6667 to both sides and then divide both sides by 3: y = (1 + 9.6667)/3. You will find that y = 3.5556 approx.
This value, 3.5556, is the value of y in the solution for the system of equations.

The volume of a cylinder with a base of radius ris the area of the base times
the length of its height (h). Which of the following is the formula for the
volume of a cylinder?
Please look at attachment. Has all info needed. Need help
Step-by-step explanation:
When the object hits the ground, h = 0.
0 = -21.962x + 114.655
x = 5.2
From the table, the object landed at x = 4.6 seconds. So the line of best fit predicts a time 0.6 seconds greater than actual.
The original height is when x = 0.
h = -21.962(0) + 114.655
h = 114.7
So the line of best fit predicts the object was dropped from a height of 114.7 meters. This is higher than the actual 100 meters.
At x = 3.5:
h = -21.962(3.5) + 114.655
h = 37.8
So the line of best fit estimates the object reached a height of 37.8 meters after 3.5 seconds.
We know that at x = 0, h = 114.7. This is more than 4 meters from the actual initial height of 100 m.
Therefore, the answer must be A.
Answer:
A. According to the line of best fit, the object would have hit the ground 0.6 seconds later than the actual time the object hit the ground.
