Answer:
x=50°
Step-by-step explanation:
x+3°+x+20°+x+7°=180°
or,3x+30°=180°
or,3x=150°
or,x=50°
Answer:
50
Step-by-step explanation:
→ First add all the angles together as angles on a straight line add to 180°
x + 3 + x + 20 + x + 7 = 180
→ Simplify
3x + 30 = 180
→ Minus 30 from both sides
3x = 150
→ Divide both sides by 3
x = 50

If f(x) = + 8, what is f(x) when x = 10?
O4
O 9
O 13
O 36
Answer:
4 step by step explanation
The at {x} = 10, the value of the function remains +8.
What is function?A function is a relation between a dependent and independent variable. We can write the examples of functions as -
y = f(x) = ax + b
y = f(x, y, z) = ax + by + cz
Given is that the function f(x) is defined as -
f(x) = + 8
The given function is a constant function. This means that the value of the function remains the same irrespective of the value of {x} or the value in the function domain. So, at {x} = 10, the value of the function remains +8 only. This is true for all the values of {x}.
Therefore, the at {x} = 10, the value of the function remains +8.

|6a-5|=4a
the solutions are a= and a=
Answer:
a = 2.5, a = 0.5
Step-by-step explanation:
6a - 5 = 4a, and 6a - 5 = -4a
6a -5 = 4a
Subtract 6a from both sides
-5 = -2a
a = 2.5
6a - 5 = -4a
Subtract 6a from both sides
-5 = -10a
a = 0.5

-Chetan K
Answer:
a=1/2 and a=5/2
Step-by-step explanation:
6a-5=4a:
Subtract 4a from both sides, ending up with 2a-5=0
Add 5 to both sides, ending up with 2a=5
Divide both sides by 2, ending up with a=5/2
6a-5=-4a
Add 4a to both sides ending up with 10a-5=0
Add 5 to both sides ending up with 10a=5
Divide both sides by 10 ending up with a=1/2

round off 19340 to 1 s f
Answer:
20000
Step-by-step explanation:
This is because when you round to the signifigant figure, you basically look at any digits at the start of the number, which isn't zero. In this case it would be in the ten thousand 19340. So you round 19340 to the nearest 10 thounsand, which, would be 20000
Explain what is the difference between radius
and circumference
Answer:
The circumference is the perimeter, specifically the perimeter of a circle. It can be solved by using the following formula:
C = 2πr
C stands for circumference.
π stands for pi, or 3.14 (rounded).
r stands for radius.
The radius is the distance from the center point of the circle to any point on the circle. It is denoted by the variable, r, as stated above. It is 1/2 of the diameter.
Answer:
the radius is the line from center to perimeter and circumference is the enclosed boundary
Step-by-step explanation:
radius- is any of the line segments from a circle or spheres center to its perimeter
circumference- the enclosed boundary a curved geometric figure, especially a circle

2x^2+ 1 = 5x
Answer:
[tex]\frac{5+\sqrt{17}}{4}[/tex], [tex]\frac{5-\sqrt{17}}{4}[/tex]
Step-by-step explanation:
One is asked to find the root of the following equation:
[tex]2x^2+1=5x[/tex]
Manipulate the equation such that it conforms to the standard form of a quadratic equation. The standard quadratic equation in the general format is as follows:
[tex]ax^2+bx+c=0[/tex]
Change the given equation using inverse operations,
[tex]2x^2+1=5x[/tex]
[tex]2x^2-5x+1=0[/tex]
The quadratic formula is a method that can be used to find the roots of a quadratic equation. Graphically speaking, the roots of a quadratic equation are where the graph of the quadratic equation intersects the x-axis. The quadratic formula uses the coefficients of the terms in the quadratic equation to find the values at which the graph of the equation intersects the x-axis. The quadratic formula, in the general format, is as follows:
[tex]\frac{-b(+-)\sqrt{b^2-4ac}}{2a}[/tex]
Please note that the terms used in the general equation of the quadratic formula correspond to the coefficients of the terms in the general format of the quadratic equation. Substitute the coefficients of the terms in the given problem into the quadratic formula,
[tex]\frac{-b(+-)\sqrt{b^2-4ac}}{2a}[/tex]
[tex]\frac{-(-5)(+-)\sqrt{(-5)^2-4(2)(1)}}{2(2)}[/tex]
Simplify,
[tex]\frac{-(-5)(+-)\sqrt{(-5)^2-4(2)(1)}}{2(2)}[/tex]
[tex]\frac{5(+-)\sqrt{25-8}}{4}[/tex]
[tex]\frac{5(+-)\sqrt{17}}{4}[/tex]
Rewrite,
[tex]\frac{5(+-)\sqrt{17}}{4}[/tex]
[tex]\frac{5+\sqrt{17}}{4}[/tex], [tex]\frac{5-\sqrt{17}}{4}[/tex]

The circumference of a circular garden is 113.04 feet. What is the radius of the garden? Use 3.14 for pie and do not round your answer.
Answer:
18 ft
Step-by-step explanation:
The circumference of a circle is given by
C = 2 * pi *r
113.04 = 2 ( 3.14) * r
113.04 = 6.28 r
Divide each side by 6.28
113.04/6.28 = 6.28r/6.28

B. b2 – 4ac = 6
C. b2 – 4ac = –2
Answer:
A. b2 – 4ac = 0
Step-by-step explanation:
Hey user☺☺
Option a is correct
Because the graph has only one solution.
As the graph touches the x-axis at one point that means that it will have only one solution for x. But we know that a quadratic equation has two solutions. So the graph will have two equal solution and therefore the discriminant will be 0.

A new cars salesperson, sold an average of $32,130 per day for the first 4 days she worked. The next 5 days she worked, she sold an average of $31,173. How much did she sell on average per day over the entire time she worked??
Answer:
$31,598.33
Step-by-step explanation:
she worked 4+5=9 days.
due the total average we need the total of sales and divide it by the length of the observation period (9 days).
how much did she sell in total on the first 4 days ?
well, the average times 4 = 32130×4 = $128520
how much did she sell in total during the following 5 days ?
31173×5 = $155865
so, the daily average is
($128520 + $155865) / 9 =$284385 / 9 = $31,598.33
