Answer:
They will be able to have their break together in 60 minutes.
Step-by-step explanation:
You will have to find the least common multiple (LCM) between 20 and 30.
The prime factorization of 20 is: 2 x 2 x 5
The prime factorization of 30 is: 2 x 3 x 5
Eliminate the duplicate factors of the two lists, then multiply them once with the remaining factors of the lists to get lcm(20,20) = 60
if f(x) and f^-1(x) are inverse functions of eachother and f(x)=2x+5, what is f^-1(8)
Answer:
1.5
Step-by-step explanation:
The value of x such that f(x) = 8 is ...
8 = 2x +5
3 = 2x
1.5 = x
f^-1(8) = 1.5

Answer:
EF = 32
Step-by-step explanation:
DE + EF = DF

If EC bisects BED, find m BED.

B. 130°
C. 134°
D. 136°
Answer:
19x+22
Step-by-step explanation:
Answer:
D. 136°
Step-by-step explanation:
[tex]\because \overrightarrow{EC} \:bisects \: \angle BED. \\
\therefore m\angle BEC = m\angle DEC\\
\therefore (11x+2)\degree = (8x+20)\degree \\
\therefore 11x + 2 = 8x + 20\\
\therefore 11x - 8x = 20-2\\
\therefore 3x = 18\\
\therefore x = \frac{18}{3}\\
\therefore x = 6\\\\
\because m\angle BED= m\angle BEC + m\angle DEC\\
\therefore m\angle BED= (11x+2)\degree + (8x+20)\degree\\
\therefore m\angle BED= (19x+22)\degree \\
\therefore m\angle BED= (19\times 6+22)\degree \\
\therefore m\angle BED= (114+22)\degree \\

An egg is dropped from a height of 90 ft. If acceleration due to gravity is –16 ft/s2 and initial velocity is 0 ft/s, approximately how long will it take for the egg to reach the ground? h(t) = at2 + vt + h0 1.9 s 2.4 s 9.7 s 40.7 s
Answer:
B
Step-by-step explanation:
I answered it on edge
2.45 seconds will it take for the egg to reach the ground.
What is height?Height can be defined the vertical distance from the top to the base of the object.
Given
Height h(t) = 90 ft
Acceleration due to gravity a = -16 ft/[tex]s^{2}[/tex]
Initial velocity v = 0
[tex]h_{0}[/tex] = 0
[tex]h(t) = at^{2} +vt+h_{0}[/tex]
90 = 16[tex]t^{2}[/tex] + 0
90 = 16[tex]t^{2}[/tex]
[tex]t^{2} = \frac{90}{16}[/tex]
[tex]t^{2}=5.625[/tex]
t = [tex]\sqrt{5.625}[/tex]
t = 2.45
Hence, 2.45 seconds will it take for the egg to reach the ground.

How do you solve for x and y in this matrix equation?
Answer:
Hi!
I might be able to help you!
The Matrix Solution
It means that we can find the values of x, y and z (the X matrix) by multiplying the inverse of the A matrix by the B matrix.
The matrix method is similar to the method of Elimination as but is a lot cleaner than the elimination method. Solving systems of equations by Matrix Method involves expressing the system of equations in form of a matrix and then reducing that matrix into what is known as Row Echelon Form.
