Use 30-60-90 or 45-45-90 triangle relationships to find the missing variable
Answers
Answer:
Step-by-step explanation:
it is 30-60-90
triangle.
so smaller side is half the hypotenuse.
x=(10√3)/2=5√3
if hypotenuse=10√5,then x=10√5/2=5√5

Answer:
g(q) = [tex]\frac{5q}{8}[/tex]
Step-by-step explanation:
Given
- 7q + 12r = 3q - 4r
Rearrange making r the subject
Add 7q to both sides
12r = 10q - 4r ( add 4r to both sides )
16r = 10q ( divide both sides by 16 )
r = [tex]\frac{10q}{16}[/tex] = [tex]\frac{5q}{8}[/tex] , thus
g(q) = [tex]\frac{5q}{8}[/tex]
-7q-3q=-4r-12r
-10q=-16q
Q=8/5r
If the probability of turning left is 0.5 and the probability of
turning right is 0.5 for each mouse, what is the probability that ONLY ONE
of the two mice will turn left? *
Answers
Answer:
0.5
Step-by-step explanation:
The probability that the first mouse turns left and the second mouse turns right is 0.5 × 0.5 = 0.25.
The probability that the first mouse turns right and the second mouse turns left is 0.5 × 0.5 = 0.25.
So the probability that only one mouse turns left is:
P = 0.25 + 0.25
P = 0.5
Another way of looking at it: the probability that only one mouse turns left is 1 minus the probability that both turn left or both turn right.
P = 1 − (P(both left) + P(both right))
P = 1 − (0.5 × 0.5 + 0.5 × 0.5)
P = 0.5

The variable is the main part, it is the base of the whole thing that shows all the critical points for the inequality ? , x = 1, and x = 2 x = –6 and x = 2 x = –4 and x = 2 x = 2.
How do you find the critical points of an inequality?Solve a rational inequality.
Determine the critical points–the points where the rational expression will be zero or undefined. Use the critical points to divide the number line into intervals. Test a value in each interval. Above the number, the line shows the sign of each factor of the rational expression in each interval.
How do you find the critical points of a function?To find the critical points of a function y = f(x), just find x-values where the derivative f'(x) = 0 and also the x-values where f'(x) is not defined. These would give the x-values of the critical points and substituting each of them in y = f(x) will give the y-values of the critical points.

Without drawing the graph of the function y=1.2x−7, see if the graph passes through points: (100; 113)
Answers
Answer:
The graph of the function passes through the point (100; 113).
Step-by-step explanation:
In order to calculate if the graph of the function passes through the point or not, we need to insert the point's coordinates in the function and check if the equation is valid or not, if it is, then the graph passes through them.
[tex]y(x) = 1.2*x - 7\\y(100) = 1.2*100 - 7\\y(100) = 120 - 7 \\y(100) = 113[/tex]
Which is equal to the "y" coordinate of the point, therefore the graph of the function passes through the point (100;113).
Answer:
yes

The product of two rational numbers is ______ rational.
Answers
The product of two rational numbers is always rational
Proof:
Let a = p/q and b = r/s be two rational numbers. We will have p,q,r,s be integers where denominators q and s are nonzero. We cannot divide by zero.
Multiplying a and b gives
a*b = (p/q)*(r/s) = (p*r)/(q*s)
Due to the closure property of integer multiplication, the expressions p*r and q*s are integers. The result we get is in the form of integer/integer. Basically we have two integers being divided. Furthermore, q*s is nonzero as neither q nor s is zero.
Therefore, if a and b are rational, then a*b is also rational as well.
