Answer:
The hourly rate is better between 1 and 8 hours.
Step-by-step explanation:
There are two options
A fixed amount of $1560.
Or an hourly rate of $180 the hour.
So for the first option, the cost equation as a function of time, t, is:
f(t) = $1560
(it does not depend on t)
While for the second option, the equation would be:
g(t) = $180*t
First, we want to answer:
We can expect that for smaller values of t the second option is better but let's see that:
or what lengths of time would the hourly rate be less expensive?
Then we need to solve:
f(t) = g(t)
for t, this is:
$1560 = $180*t
$1560/$180 = t = 8.66
So, for t = 8.66, the cost is the same in both options.
For t < 8.66
(between 1 and 8 hours) the second option is better. (here the hourly rate is better)
for t > 8.66
(9 hours or more) is better the first option, as the hourly (here the flat fee is better)

The angles represented by (2x - 60) and (60 - 2x) cannot be supplementary because their sum add up to zero instead of 180°.
What’s the value of x?
G
53°
45
H
x°
Answer:
x = 98°
Step-by-step explanation:
95 + 53 + (180 - x) = 180
148 + 180 - x = 180
328 - x = 180
328 - x + x = 180 + x
x + 180 = 328
x + 180 - 180 = 328 - 180
x = 98°
The required measure of the remote exterior angle x is 98°.
Given that,
A triangle has shown,
Where two remote interior angles with measures 45° and 53° are given and a remote exterior angle with measure x is given, we have to determine the value of x.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
What is the angle?The orientation of one line with respect to the horizontal or other respective line is known as a measure of orientation and this measure is known as the angle.
Here,
There is a property of a triangle that, the sum of the remote interior angle is equal to the measure of the remote exterior angle. So,
x = 53 + 45
x = 98°
Thus, the required measure of the remote exterior angle x is 98°.

x = 3/4
Step-by-step explanation:
5/2-3x-5+4x=-7/4
Combine like terms
-10/2 + 5/2 +x = -7/4
-5/2+ x = -7/4
Add 5/2 to each side
-5/2+5/2 +x = -7/4 + 5/2
x = -7/4+5/2
Get a common denominator
x = -7/4 + 10/4
x = 3/4

Using the graph, determine the coordinates of the vertex of the parabola.
Answer:
The coordinates of the vertex is (6,4).
Step-by-step explanation:
The vertex is the highest or lowest point on the parabola (curved line).
In the diagram below, the area of $\triangle BCD$ is 60. What is the length of side $\overline{BC}$?
Area of triangle = 1/2 bh
60 = 1/2 (15) h
8 = h
Quadrilateral area = h x (b1 + b2)/2 = 8 x (15+9)/2 = 96 sq units
96 -60 = triangle BAD area = 36 sq units
The length of side BC in the triangle BCD is 8.
What is an area?An area is the amount of space occupied by a two dimensional shape or figure.
From the diagram:
Area of triangle BCD = (1/2) * base * height = (1/2) * CD * BC
60 = (1/2) * 15 * BC
BC = 8
The length of side BC in the triangle BCD is 8.

9). Dimensions of the logo = 4 inch by 6 inch
∵ 12 inches = 1 feet
∴ 1 inch = [tex]\frac{1}{12}[/tex] feet
Therefore, dimensions of the logo (in feet) will be,
[tex]\frac{4}{12}[/tex] feet by [tex]\frac{6}{12}[/tex] feet Or [tex]\frac{1}{3}[/tex] feet by [tex]\frac{1}{2}[/tex] feet
Dimensions of the logo which are 6 times larger than the original one.
Dimensions of the advertisement = [tex]\frac{6}{3}[/tex] feet by [tex]\frac{6}{2}[/tex] feet

What is the relative frequency (to the nearest percent) of boys among those who cannot bike to school
Answer:
29%
Step-by-step explanation:
From the two way table given : the relative frequency of boys among those who cannot bike to school ;
Here, we are only concerned with thilose who cannot Bikento school and not all of the data :
The relative frequency of boys among those who cannot bike to school is :
Number of boys who can't bike to school / total number of people who can't bike to school
Number of boys who can't bike = 4
Total who cannot bike = 14
Hence, 4 /14 = 0.2857142
0.2857142 * 100% = 28.57% = 29% (nearest percent)

SOMEONE HELP ME ASAP IM STRESSING OUT
Answer:
Use SOHCAHTOA
Step-by-step explanation:
If you don't know what this is, it means Sin=opposite/hypotenuse, cos=adjacent/hypotenuse, tan=opposite/adjacent. There is more than 1 way to solve this, but here's how I did it.
Starting with part A, we are trying to find the hypotenuse of the triangle. We have an angle and the side opposite of that angle, so we can use the sin function.
Sin(54) = 12.2 / hypotenuse
Sin(54) * hypotenuse = 12.2
Hypotenuse = 12.2 / sin(54) = 15.1
Now for Part B
Finding the last angle
180-90-54=36
So now, we have this angle and the side adjacent to it. We are trying to find the opposite side, so let's use the tan function
Tan(36) = opp / 12.2
opp = tan(36) * 12.2 = 8.9
You can double check these answers using pythagorean theorem. Hope this helps
Ellen divides a piece of fabric into 8 equal sections by drawing chalk lines. Then she cuts off 5 of the sections to make into placemats. What fraction of the fabric is left?
Answer:
3/8
Step-by-step explanation:
Let us represent the total fabric as an integer = 1
Ellen divides a piece of fabric into 8 equal sections by drawing chalk lines.
= 1/8, hence each section = 1/8
Then she cuts off 5 of the sections to make into placemats.
This is written as: 5 sections × 1/8 = 5/8
The fraction of the fabric that is left is calculated as:
1 - 5/8
Lowest Common Denominator = 8
Hence: 8 - 5/8 = 3/8
The fraction of the fabric that is left is 3/8
