Using the Triangle Sum Theorem. Determine the angle measure
of <1.
38
31
(78 and 31 degrees)
Answers
Answer:
71 degrees
Step-by-step explanation:
Hi there!
The sum of the interior angles of a triangle is always 180 degrees.
Knowing this, to solve for the measure of angle 1, subtract 78 and 31 degrees from 180:
180-78-31
= 71
Therefore, angle 1 measure 71 degrees.
I hope this helps!

The only ones are the first and last, not the “y=“ ones.
Then look at the equations.
h(x) = x^2 would be a parabola, so the range wouldn’t be all real numbers. It’d only be non-negative numbers.
g(x) = 1/2 x + 3/2 would be a line. This has a range of all real numbers.

On the coordinate plane, a line with a positive slope passes through the points (0, negative 1) and (1, 1).

The equation for line a is shown. y=-2/3 x-4
line a and b are parallel, and the point (-2,1) lies on line b. write the equation for line b
Answers
Step-by-step explanation:
line a slope (x coefficient)= -2/3
Parallel lines have the same slope and will never intersect.
line b slope = -2/3
line equation =
y =mx + b
m = slope
y= -2/3 x + b
from the point given (-2,1)
x = -2
y = 1
1 = 4/3 + b
b = -1/3
b equation =
y = (-2/3)x - (1/3)

A national survey asked people, "How often do you eat out for dinner, instead of
at home?" The frequencies were as follows. Complete parts (a) through (g)
Answers
A relative frequency table is used to display the proportion of variables, in a tabular form.
3.1% of the respondents responds always32.5% of the respondents responds never or rarely.(a) Draw the Relative Frequency
To do this, we simply divide the frequency of each response by the total frequency.
The total frequency is:
[tex]Total = 326 + 304 + 992 + 257 + 61[/tex]
[tex]Total = 1940[/tex]
So, the calculation of the relative frequency table is as follows:
[tex]Never = \frac{326}{1940}=0.168=16.8\%[/tex]
[tex]Rarely = \frac{304}{1940}=0.157=15.7\%[/tex]
[tex]Sometimes = \frac{992}{1940}=0.511=51.1\%[/tex]
[tex]Most\ times = \frac{257}{1940}=0.132=13.2\%[/tex]
[tex]Always = \frac{61}{1940}=0.031=3.1\%[/tex]
The relative frequency table is:
[tex]\left[\begin{array}{ccc}{Response}&{Frequency}&{Relative\ Frequency}\\Never&326&16.8\%\\Rarely&304&15.7\%&Sometimes&992&51.1\%&Most\ Times&257&13.2\%&Always&61&3.1\%\end{array}\right][/tex]
(b) Percentage that responds always.
From the above calculation, we have:
[tex]Always = 3.1\%[/tex]
Hence, 3.1% responds always
(c) Percentage that responds never or rarely.
From the above calculation, we have:
[tex]Never = 16.8\%[/tex]
[tex]Rarely =15.7\%[/tex]
So, we have:
[tex]Never\ or\ Rarely = Never + Rarely[/tex]
[tex]Never\ or\ Rarely = 16.8\%+ 15.7\%[/tex]
[tex]Never\ or\ Rarely = 32.5\%[/tex]
Hence, 32.5% responds never or rarely.
(d) The frequency bar graph
To do this, we plot the response against the frequency

Answer:
Smaller angle = 70 degrees
Step-by-step explanation:
Supplementary angles = add up to 180 degrees
let x = bigger angle
smaller angle = (x/2) + 15
x + (x/2) + 15 = 180
x + 0.5x + 15 = 180
1.5x = 165
x = 110
180 - 110 = 70
or
(x/2) + 15 = (110/2) + 15 = 55 + 15 = 70

Answer:
Step-by-step explanation:
-37 = 4x-1 = 37 (absolute value = negative and positive answer)
-37 = 4x-1

4x - 1 = 37
4x = 38

| 7x-2 | +3 = -1 solve for x
Answers
Answer:
x = -2/7 or
x = 6/7
Step-by-step explanation:
|7x-2| + 3 = -1 subtract 3 from both sides
|7x-2| = -4 now there are two probabilities
7x-2 = -4 or
7x-2 = 4 if first probability the value of x would be:
7x-2 = -4 add 2 to both sides
7x = -2 divide both sides by 7
x = -2/7 for the second probability the value of x would be:
7x-2 = 4 add 2 to both sides
7x = 6 divide both sides by 7
x = 6/7

Answer: According to the universe in which your light only moves at 3x10^5 meters/sec, it would take 3.333x10^-6 seconds to go 1 meter. Where I live (Earth in the Milky Way Galaxy), light travels 3x10^8 m/s. It only requires 3.33x10^-9 second. So there . . .
Step-by-step explanation:
The speed of light is in units of meters/sec. If it is 3x10^5 meters/sec, we can also write the inverse:
1 sec/3x10^5 meters [It takes 1 sec to go 3x10^5 meters]
Do the division to find seconds per 1 meter: 3.333x10^-6 seconds.
