Step-by-step explanation:
Find the measures of two complementary angles if the difference in their measures is 16.
Answer:
One of the angles is 53 degrees and the other is 37 degrees.
Step-by-step explanation:
Let x be equal to the measure of the first angle.
Let y be equal to the measure of the second angle.
Because x and y are complementary, they add up to 90 degrees.
x+y=90
The question tells us that x and y have a difference of 16.
x-y=16
Now that we have our two equations, we can use the method of elimination to find the value of x (process is in the picture attached). We do this by adding the two equations since y will cancel out.
x=53
Finally, we can plug x back into either of the original equations to find the value of y.
x+y=90
53+y=90
Subtract both sides by 53 to isolate y
53+y-53=90-53
y=37

A submarine is 4,000 feet below sea level, and rising a rate of 100 feet pre minute. Write an equation to represent y, the depth of the submarine after x minutes.
Answer:
y = 100x - 4000Step-by-step explanation:
Initial elevation is a starting point, therefore y-intercept is -4000The rate of change is the slope, therefore m = 100The equation of the linear function is:

What the slope of the line on the graph please help me
Answer: y=-3/7x+3
Step-by-step explanation:
I gave you the intercept form of slope as well, although you did not ask for it.
Your line angled downwards (reading it left to right) meaning that your slope is negative. Your slope also goes down by 3 and to the right by 7, which is where your 'rise over run' is acquired from.
Rise over run (slope), when positive, is either up/right or down/left
Rise over run (slope), when negative, is either down/right or up/left

The _______________ property states: a plus b equals b plus a
1. associative
2. commutative
3. inverse
4. identity
The 2) commutative property states that A plus B equals B plus A.
What is the commutative property?The commutative property of addition or multiplication implies that changing the order of numbers for the addition or multiplication operation cannot change the result.
Reordering the addends does not change the outcome of the addition of multiplication operations.
Apart from the commutative property, there are other number properties, including:
Associative propertyDistributive propertyClosure propertyInverse propertyIdentity property.For instance, 3 + 5 = 8, and 5 + 3 = 8. Agains 3 x 5 = 15, as 5 x 3 = 15.
Thus, the 2) commutative property states that A plus B equals B plus A.

Step-by-step explanation:
Given:
Total sample n = 200
Yield x = 35
Confidence level = 90%
Find:
Proportion non-conforming
Computation:
Proportion p = x / n
Proportion p = 35 / 200 = 0.175
Non Proportion q = 1 - p
Non Proportion q = 0.825
So,

One week a student exercised 3 hours at school and another 2/3 of an hour at home. If 1/6 of the student’s total exercise came from soccer, how much time did the student spend playing soccer that week?
Answer:
36m 40s
Step-by-step explanation:
To find out how much time was spent on playing soccer, we need to find out the total number of hours spent on exercising.
Total amount of time for exercise = 3h + [tex]\frac{2}{3}[/tex]h
= [tex]\frac{11}{3}[/tex]h
Total amount of time for soccer = [tex]\frac{1}{6}[/tex] × [tex]\frac{11}{3}[/tex]h
= [tex]\frac{11}{18}[/tex]h
= 36m 40s

What is the value of g(f(x)) ? Ο Α. . -6 OB. C. 19 D. 31
Answer:
D. 31
Step-by-step explanation:
Given:
[tex] f(x) = 4x^3 - 10 [/tex]
[tex] g(x) = \frac{3x - 4}{2} [/tex]
Required:
The value of g(f(2))
First, find f(2).
Substitute x = 2 into [tex] f(x) = 4x^3 - 10 [/tex].
[tex] f(2) = 4(2)^3 - 10 [/tex]
[tex] f(2) = 4*8 - 10 = 32 - 10 [/tex]
[tex] f(2) = 22 [/tex]
Next, find g(f(2)).
[tex] g(f(x)) = \frac{3(22) - 4}{2} [/tex]
[tex] g(f(x)) = \frac{66 - 4}{2} [/tex]
[tex] g(f(x)) = \frac{62}{2} [/tex]
[tex] g(f(x)) = \frac{62}{2} [/tex]
[tex] g(f(x)) = 31 [/tex]
