Answer:
DOMAIN: -5, 2, 3 ,4
RANGE: 1, 3, 3 , 5
FUNCTION: Yes
Step-by-step explanation:
Since there is one value of y for every value of x this is a function.
The domain is just the x value (first number) and the range is just the y value(second number).
ANSWER: $65.63
$50 divided by 4 hours = $12.50 per hour
1/4 can also be written as the fraction 0.25
So 5 1/4 hours is the same as 5.25 hours
$12.50 per hour x 5.25 hours = $65.625 rounded to the nearest cent = $65.63
Answer:
∠a = 39°
∠b = 129°
Step-by-step explanation:
Vertical angles are congruent. An exterior angle of a triangle is equal to the sum of the remote interior angles.
<h3>Application</h3>
Angle y and angle 'a' are vertical angles, so congruent.
∠a = ∠y = 39°
The angle marked 'b' is an exterior angle to the triangle. Its remote interior angles are 'a' and the one marked 90°.
∠b = ∠a +90° = 39° +90°
∠b = 129°
ANSWER
Find out the expression gives the percent of survey participants who chose swimming.
To proof
As given
75 girls at a summer camp were asked to complete a survey about their favorite outdoor activity.
27 girls chose swimming
32 girls chose hiking.
FORMULA
total girls = 75
girls chose swimming = 27
put in the formula
= 36%
36% of survey participants who chose swimming
Hence proved
Okay I am not 100% sure because that is an extremely confusing question. But here is what I got.
(A) 2c² = 2bc + ac/2 Given
(B) 4c² = 2bc + ac Multiplication and Distribution
(C) 4c = 4b + a Division and Distribution
(D) 4c - a + 4b Subtraction
(E) 4b = 4c - a Symmetric
