Answer:
32
Step-by-step explanation:
first angle is 20, let third angle be x, therefore second angle equals 4x; angle in a triangle is 180, so 4x+x+20=180; 5x=160; x=32

Theodore invests a total of $19,500 in two accounts paying 8% and 15% simple interest, respectively. How much was invested in each account if, after one year, the total interest was $2,400.00
A) Enter an equation that uses the information as it is given that can be used to solve this problem. Use x as your variable to represent the amount of money invested in the account paying 8% simple interest.
Answer:
[tex]x+y=19500,\:0.08x+0.15y=2400\quad :\quad x=7500,\:y=12000[/tex]
Step-by-step explanation:
x + y = 19500
.08x + .15y = 2400

plot function f on the graph f(x) = |1/2x - 2|
Answer:
See attachedStep-by-step explanation:
Given function:
f(x) = |1/2x - 2|The function is plotted and it is below.
The graph of the function f(x) = | (x/2) - 2 | is attached with the answer the lines of the function meet at point 4 at the x-axis.
What is a graph?
A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.
The graph of the function f(x) = | (x/2) - 2 | is attached with the answer the lines of the function meet at point 4 at the x-axis.
Therefore graph of the function f(x) = | (x/2) - 2 | is attached with the answer the lines of the function meet at point 4 at the x-axis.

plz someone help I will mark brainlest diameter is 8.8 yd
Answer:
60.79 square yards.
Step-by-step explanation:
d = 2r; d = 8.8.
8.8 = 2r
r = 8.8 / 2
r = 4.4 yards.
Since we now have the radius, we can find the area of the circle, which can be found using πr^2, or 3.14 * r^2.
4.4^2 * 3.14 = 19.36 * 3.14 = 60.7904.
Since the question tells us to round to the nearest hundredth, our final answer will be 60.79 square yards.
Hope this helps!

* 1. Find the two roots X7 and x2 of the quadratic equation x2 – 8x + 12 = 0. Enter y
9514 1404 393
Answer:
x = 2, x = 6
Step-by-step explanation:
The quadratic can be factored as ...
x^2 -8x +12 = 0
(x -2)(x -6) = 0
Solutions are the values of x that make these factors zero:
x -2 = 0 ⇒ x = 2
x -6 = 0 ⇒ x = 6
there were 450 balloons in all a total of 60% were used to how many were used
Let used balloon be x

Step-by-step explanation:
Solution,
Let the number of used balloons be x,Given:-
Total number of balloons= 450Used percentage of balloons= 60%Now,
Number of used balloons(x)=
60% of 45060/100×450270Hence, 270 balloons were used.

Step-by-step explanation:
Plug x + h into the function f and simplify to find f(x + h). Now that you have f(x + h), find f(x + h) - f(x) by plugging in f(x + h) and f(x) and simplifying. Plug your result from step 2 in for the numerator in the difference quotient and simplify.
