How many lengths of wire, each are 3 7/8 inches long , can be cut from a 25ft roll?
Number of [tex]3\frac{7}{8}[/tex] inches length wire that can be cut from 25ft roll is 77
Given,
The total length of the roll =25 foot
Length of each wire = [tex]3\frac{7}{8}[/tex] inches
First we have to convert mixed fraction to simple fraction
[tex]3\frac{7}{8}=\frac{31}{8}[/tex] inches
Convert foot to inches
25 foot = 25×12 =300 inches
Number of [tex]3\frac{7}{8}[/tex] inches length wire that can be cut from 25ft roll = Total length of the roll/ Length of each wire
=300÷[tex]\frac{31}{8}[/tex]

The supplement of an angle is 26 more than five times its complement. Find the measure of the angle
x = 74 degrees is the angle
Let x = the angle
then
(180-x) is the supplement of x
and
(90-x) is the complement of x:
"The supplement of an angle is 26 more than 5 times its complement."
(180-x) = 26 + 5(90-x)
180 - x = 26 + 450 - 5x
-x + 5x = 26 + 450 - 180
4x = 296
x = [tex]\frac{296}{4}[/tex]
x = 74 degrees is the angle
5 times its complement.
(180-74) = 26 + 5(90-74)
106 = 26 + 5*(16)
106 = 26 + 80; confirms our solution
In elementary geometry , an angle is that the figure formed by two rays, called the edges of the angle, sharing a standard endpoint, called the vertex of the angle. Angles formed by two rays dwell the plane that contains the rays. Angles also are formed by the intersection of two planes. These are called dihedral angles. Two intersecting curves can also define an angle, which is that the angle of the rays lying tangent to the respective curves at their point of intersection.
Angle is additionally used to designate the measure of an angle or of a rotation. This measure is that the ratio of the length of a circular arc to its radius. within the case of a geometric angle, the arc is centered at the vertex and delimited by the edges . within the case of a rotation, the arc is centered at the middle of the rotation and delimited by any other point and its image by the rotation.
Potentially, an angle denoted as, say, ∠BAC, might ask any of four angles: the clockwise angle from B to C, the anticlockwise angle from B to C, the clockwise angle from C to B, or the anticlockwise angle from C to B, where the direction during which the angle is measured determines its sign (see Positive and negative angles).

Josie earns $10 per hour at her job. Her hours vary, but she never works more
than 30 hours in any given week, as she is still in school. We want to write and
graph a function to show her possible earnings for one week.
What is a reasonable domain and range within the context of this situation?
Answer:
Step-by-step explanation:
Work for 30 hours in a week $10 per hour
The domain and the range for the given situation will be:
Domain = [0, 30]
Range = [0, 300]
Given that Josie earns $10 per hour at her job. Her hours vary, but she never works more than 30 hours in any given week,
We need to find the domain and range.
In this situation, the domain refers to the possible values for the input variable, which is the number of hours Josie works in a given week.
The range, on the other hand, refers to the possible values for the output variable, which is her earnings for the week.
For the domain:
Since Josie never works more than 30 hours in any given week, a reasonable domain for this function would be from 0 to 30 hours. We don't consider negative hours (as it doesn't make sense in this context), and the upper limit is set by her maximum weekly working hours.
Domain = [0, 30]
For the range:
The range should be the possible earnings Josie can make in a week based on her hourly rate of $10 per hour.
To find the range, we multiply her hourly rate by the maximum number of hours she can work in a week, which is 30 hours.
Range = [0, 10 x 30] = [0, 300]
So, the function that represents Josie's possible earnings for one week is:
Earnings = f(hours) = 10 x hours
Where "hours" is the number of hours she works in a week, and "Earnings" is the corresponding amount she earns.
The graph of this function will be a straight line passing through the origin (0, 0) and with a slope of 10, representing her earnings increasing linearly with the number of hours worked.
The line will extend up to the point (30, 300) and then flatten out as she cannot earn more than $300 in a week.

If yacht is sailed from A to B on a bearing of 196ºT, the true bearing to sail directly back to point A from point B is 16° T.
To determine the true bearing from point B back to point A, we need to consider the relationship between true bearings and the reciprocal direction.
Given that the yacht is sailed from point A to point B on a bearing of 196° T (True), the reciprocal direction would be the opposite direction, 180° away on the compass.
Thus, to sail directly back to point A from point B, we would need to subtract 180° from the reciprocal direction.
