Consider the system of inequalities and its graph.
y ≥
y ≤ x – 3
On a coordinate plane, 2 solid straight lines are shown. The first line has a positive slope and goes through (negative 8, negative 2) and (0, 0). Everything above the line is shaded. The second line has a positive slope and goes through (0, negative 3) and (3, 0). Everything to the right of the line is shaded. The section in quadrant 1 is labeled 3, the section in quadrant 2 is labeled 2, the section in quadrant 3 is labeled 1, and the section in quadrant 4 is labeled 4.

Answer:
[tex]10^{-6}[/tex]
Step-by-step explanation:
Start with 0000008.0
For each decimal place you move back, subtract the exponent (the n value of [tex]10^n[/tex]) by 1. In this case, we move back 6 places. This makes n = 6, giving us an answer of [tex]10^{-6}[/tex].

Beetle cellular offers cellular phone service for 39.95 a month plus one cent a minute. Salamander digital offers cellular phone service for 9.95 a month plus five cents a minute. How many minutes would a person need to use a month for beetle cellular to cost the same as salamander digital
Answer:
750 minutes
Step-by-step explanation:
Let the number of minutes be represented as x
1 cent = 0.01
Beetle cellular offers cellular phone service for 39.95 a month plus one cent a minute.
$39.95 + 0.01x
Salamander digital offers cellular phone service for 9.95 a month plus five cents a minute.
$9.95 + 0.05x
How many minutes would a person need to use a month for beetle cellular to cost the same as salamander digital?
This is calculated as:
Beetle cellular = Salamander digital
$39.95 + 0.01x = $9.95 + 0.05x
Collect like terms
$39.95 - $9.95 = 0.05x - 0.01x
$30.00 = 0.04x
x = $30.00/0.04
x = 750 minutes
A person need to use 750 minutes a month for beetle cellular to cost the same as salamander digital.

A sculpting tool is in the shape of a solid triangular prism. The tool is made of 12 in.3 of metal and is 4 in. Long. What is the height of the base if it is 2 in. Wide?
Answer:
The height of the base if it is 2 in. Wide is 3 inches
Step-by-step explanation:
Volume of rectangular prism = [tex]\frac{1}{2} \times Length \times Base \times Height[/tex]
Volume of given rectangular prism = [tex]12 in^3[/tex]
Length of prism = 4 in
Base of prism = 2 in
Substitute the values in formula
So, [tex]12 = \frac{1}{2} \times 4 \times 2 \times Height[/tex]
[tex]\frac{12 \times 2}{4 \times 2}=Height[/tex]
3 = Height
Hence the height of the base if it is 2 in. Wide is 3 inches
Answer:
3 inches

Answer:
Did you find the answer? I need help with this too
Step-by-step explanation:
An airline has two flights each day from City A to City B. A random sample of 10 morning flights left the gate an average of 15 minutes late with a standard deviation of 5 minutes. A random sample of 10 evening flights left the gate an average of 20 minutes late with a standard deviation of 3 minutes. Suppose both the morning and evening flights are 30 minutes late. To determine which flight is more late than usual, first find the z-scores. Round to one decimal place if necessary.
Answer:
Step-by-step explanation:
Let X denote the random variable that obeys the normal distribution.
Given that:
For morning flights
Mean [tex]\mu_1[/tex] = 15
standard deviation [tex]\sigma_1[/tex] = 5
Sample size [tex]n_1[/tex] = 10
[tex]X_1 \sim Normal ( \mu_1, \sigma _1)[/tex]
The Z - score is calculated as:
[tex]Z = \dfrac{x_1 - \mu_1}{\sigma_1}[/tex]
[tex]Z = \dfrac{30 -15}{5}[/tex]
[tex]Z = \dfrac{15}{5}[/tex]
Z = 3
For evening flights
Mean [tex]\mu_2[/tex] = 20
standard deviation [tex]\sigma_2[/tex] = 3
Sample size [tex]n_2[/tex] = 10
[tex]X_2 \sim Normal ( \mu_2, \sigma _2)[/tex]
[tex]Z = \dfrac{x_2 - \mu_2}{\sigma_2}[/tex]
[tex]Z = \dfrac{30 -20}{3}[/tex]
[tex]Z = \dfrac{10}{3}[/tex]
Z = 3.33
Hence, from the above z-scores, we will realize that the evening flight is more late than usual.

Answer:
48% is A and since i like quarters more than nickels and dimes its c for 30
Step-by-step explanation: Because I said so.
Answer:
To calculate the average you must add the percentages up and divide by the number of percentages. So, 52+28+34+95+16+63=288/6=48. The percentage is 48%.
For the second questions you take 100 divide by 3 since there are 3 coins and you get an 33.3%. But, since you can't have 0.3 of a coin. So, since you started with a nickel, you would end with a nickel giving you a percentage of 34% and the dimes and quarters a percentage of 33% each.

What is one main objective in the study of economics?

recognizing the relationship between producers and consumers
recognizing the reasons why consumers supply services
recognizing the difference between producers and consumers
Answer:
C
Step-by-step explanation:
Struggling to do my math work haha please help. Worth 14 points!!!
Answer:
C. y = -1/2 + 2
Step-by-step explanation:
First, we need to find the Slope.
Points: ( -4,4) and (8,-2)
Formula: m = y2 - y1/x2 - x1
m = y2 - y1/x2 - x1
m = -2 - 4/8 - (-4)
m = -6/8 + 4
m = -6/12
m = -1/2
Alright, now that we have the Slope, we can now use the Slope Form to find the Slope Intercept Form.
Point: (8,-2) (You may choose any points, but I would like to choose these for no reason)
Slope: -1/2
Formula: y - y1 = m(x - x1)
y - y1 = m(x - x1)
y - (-2) = -1/2(x - (8))
y + 2 = -1/2x + 4
y = -1/2 + 4 - 2
y = -1/2 + 2
The Slope Intercept Form is: y = -1/2 + 2

Answer:
The correct answer is A, 4/5 x 5/4.

Anya walked 7/10 km to the bank and then walked 3/4 km to the flower shop. What is the total distance Anya walked? Show your work. Write your answer as a mixed number.
Answer:
1 and 9/20
Step-by-step explanation:
add your fractions together 7/10 + 3/4
make them have the same denom 14/20 + 15/20
so its 29/20
to get the mixed fraction, divide 29/20 to get 1.45. The 1 is your whole number. Subtract 20 from 29 to get 9, which is what is remaining, and will go over 20.
the answer is 1 and 9/20
work:
7/10km = 14/20km
3/4km = 15/20km
15/20+14/20=29/20km
29/20 as a mixed number is 1 and 9/20.

Answer:
+2
Step-by-step explanation:
Draw a vertical line through x = -6. Determiene the corresponding y-value. It is +2. This is g(-6).
The value of the function g(x) when x = - 6, g(-6) is 2.
What is a function?A function can be defined as the outputs for a given set of inputs.
The inputs of a function are known as the independent variable and the outputs of a function are known as the dependent variable.
Given, A function g(x).
Now, The value of the function g(-6) is the same as the value of the y-coordinate when the x-coordinate is - 6.

Clare cycled a total of 6.48 kilometers by making 4 trips to work. How many trips will Clare have to make to cycle a total of 8.1 kilometers?
Answer:
5 trips
Step-by-step explanation:
6.48 km = 4 trips
1 trip = 6.48km ÷ 4 trips
1.62km = 1trip
8.1 kilometers ÷ 1 trip = 8.1 kilometers ÷ 1.62km
8.1 kilometers = 5 trips
∴ 8.1kilometers covers 5 trips

A grocery store is offering a sale on bread and soup. Khalil buys four cans of soup and
three loaves of bread for $11.67. Ronda buys eight cans of soup and one loaf of bread for $12.89.
Homework. Help
a. Write equations for both Khalil's and Ronda's purchases.
b. Solve the system to find the price of one can of soup and the price of one loaf of bread
Answer:
a) cblo
2)$3.44
Step-by-step explanation:
4 cans and 3 loaves=11.67
8 cans and 1 loaf= 12.89.
Set up equation:
x=cans
y=loaves
[tex]4x+3y=11.67\\8x+y=12.89[/tex] This is the answer for question A.
Multiply eq1 by 2:
[tex]8x+6y=23.34[/tex]
Subtract eq3 by eq2:
[tex]5y=10.45\\y=2.09[/tex]
Substitute:
[tex]8x+2.09=12.89\\8x=10.8\\x=1.35[/tex]
One can of soup and one loaf of bread=
[tex]1.35+2.09 or 3.44[/tex]
So:
[tex]$3.44[/tex]
Hope this helps :D Please hit the crown if u can !!
a. The equation should be
4x + 3y = $11.67
8x + y = $12.89
b. The price of one can of soup and the price of one loaf of bread is $1.355 and $2.09
The calculation is as follows:
here we assume the soup be x and bread be y
So, the equations are
4x + 3y = $11.67 .........(1)
8x + y = $12.89.........(2)
Here we need to multiply by 2 in equation 1
8x + 6x = $23.34
8x + y = $12.89
5y = $10.45
y = $2.09
Now x should be
8($2.09) + y = $12.89
x = $1.355
