m < ECA = 180 - 65 = 115
answer
m < ECA = 115
B. 115
The measure for <ECA is 115 degree.
What is Linear Pair?When two lines cross at one point, a linear pair of angles is created. If the angles follow the intersection of the two lines in a straight line, they are said to be linear. A linear pair's total angles are always equal to 180°. These are also referred to as additional angles.
Given:
m <ACB = 65 degree
m <ECA = ?
As. <ACB and <ECA forms a linear pair.
So, m<ACB + m<ECA = 180
64 + m <ECA = 180
m <ECA = 180 - 65
m <ECA = 115
Hence, the measure of <ECA = 115 degree.

If a function f(x) is the temperature in degrees as a function of time in minutes. then the function f'(x) is
Answers
In the context of a function representing temperature over time, the derivative f'(x) indicates the rate of change of the temperature with respect to time.
If a function f(x) represents the temperature in degrees as a function of time in minutes, the function f'(x) represents the rate of change of temperature with respect to time. This implies that if you have the temperature reading from a thermometer at different times, f'(x) tells you how quickly the temperature is rising or falling at any given moment. The concept of the derivative as the rate of change applies to many types of functions beyond just temperature over time.

What is the measure of angle WZX?
Answers
Here's how these expressions work together. First, you need to remember WZY is a right angle (90 degrees). Now, keep that in mind when we add both equation.
3c + 2c + 2 - 7 = 90
5c - 5 = 90
5c - 5 + 5 = 90 + 5
5c = 95
5c/5 = 95/5
c = 19. Now, put 19 in the place of c and solve.
3(19) + 2 = 57 + 2 =
59 degrees.
The measurement of angle WZX is equal to 59 degrees, B.

Write the equation of the line that is perpendicular to 5x+8y=16 and passes through (-5,7).
Answers
Slope Intercept form (y=mx + b), m=slope, b=y-intercept
5x + 8y = 16 Subtract 5x from both sides
8y=-5x + 16 Divide both sides by 8
y= (-5/8)x + 2
This is our line in slope-intercept form. What will the slope be of a line that is perpendicular to this one? It will be the opposite inverse of the slope of our equation. The opposite inverse means flipping the numerator and denominator, and multiplying by negative one.
Our slope = -5/8, so the opposite inverse is 8/5.
The slope of our perpendicular line will be 8/5
In slope intercept form, our line will be
y=(8/5)x + b
We know it passes through the point (-5,7), so we can plug in -5 for x and 7 for y in order to find b:
7 = (8/5) * -5 + b
7 = 8 *-1 + b Add 8 to both sides
15 = b
Plugging in b, we can get our general function in slope-intercept form:
y= (8/5)x + 15

What percent of 52 is 12? Round your answer to the nearest tenth.
Answers
The percent of 52 which result in 12 would be 23%.
How to find the percentage from the total value?Suppose the value of which a thing is expressed in percentage is "a' the percent that considered thing is of "a" is b%. Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts.
We need to find the percent of 52 which result in 12.
Let the unknown number is represneted by b.
It can be written as;
52% x b = 12
52/100 x b = 12
0.52 x b = 12
b = 12/0.52
b = 23%
Therefore, the percent of 52 which result in 12 would be 23%.

Numbers 1-30 are written on cards and placed in a bag. One card is drawn. Find each probability.
a. drawing an even number or a 1.
b. drawing an even number or a multiple of 7.
Answers
Answer:
A. [tex]\frac{8}{15}[/tex] There are 15 even number and then there is 1 so 16 possibilities in total.
B. [tex]\frac{19}{30}[/tex] There are 15 even numbers and there are 4 multiples of 7 so 19 in total.
The question requires calculating the probability of drawing an even number or a 1, and an even number or a multiple of 7 from cards numbered 1 to 30. For the first case, the probability is 16/30 and for the second case, it's 17/30, considering mutually exclusive events and counting each outcome only once.
The question involves calculating the probability of drawing specific cards from a set of numbered cards. To find the probability of a particular outcome, we divide the number of ways that outcome can occur by the total number of possible outcomes.
Probability of drawing an even number or a 1
In the set of numbers 1-30, there are 15 even numbers (2, 4, 6, ..., 30) and one number 1. Since the events 'drawing an even number' and 'drawing a 1' are mutually exclusive, we add the probabilities. There are 16 favorable outcomes (15 even numbers + 1), out of a total of 30 possible outcomes.
Probability = Number of favorable outcomes / Total number of outcomes
= 16/30
Probability of drawing an even number or a multiple of 7
Again, from numbers 1-30, we have 15 even numbers. The multiples of 7 up to 30 are 7, 14, 21, and 28. Of these, 14 and 28 are also even numbers and have already been counted. Therefore, we have 2 additional unique multiples of 7 (7 and 21) to consider. Thus, there are 17 favorable outcomes (15 even numbers + 2 unique multiples of 7).
Probability = 17/30

The measure of the value 'x' for the supplementary angles will be 22. The correct option is D.
What are supplementary angles?If two angles add up to 180 degrees, they are said to be supplementary angles. When supplementary angles are combined, they form a straight angle (180 degrees).
In other words, if Angle 1 + Angle 2 = 180°, angles 1 and 2 are supplementary. Angles 1 and 2 are referred to as "supplements" in this case.
The measure of the value x will be calculated as:-
5x + 20 + 50 = 180
5x + 70 = 180
5x = 180 - 70
5x = 110
x = 110/5
x = 22
Hence, the value of x will be 22.
