Step-by-step explanation:
3 gallons of milk in 1 week means they use 3 gallons of milk in 7 days.
To find out how much milk they use in 1 day, simply divide 3 gallons by 7.
1 day = 3/7 gallons
Then to find how much they use in 4 days, multiply the amount in 1 day by 4.
4 days = 3/7 x 4 = ? Gallons

about the graph of the system.
Solve A and B
PLEASE HELP ASAP!!!
Answer:
a: no solutions
b: (2, 3)
Step-by-step explanation:
a:
In both equations, the slope of x is the same, but the y-intercept is not, which means they are parallel. Therefore, this system of equations has no solutions.
b:
Since both of the equations are equal to y, we can set them equal to each other:
[tex]\frac{1}{2}x^2+1= 2x-1\\x^2 + 2 = 4x - 2\\x^2-4x+4=0[/tex]
We can solve by factoring (by finding a number that multiplies to 4 and adds up to -4):
(x-2)^2 = 0
x = 2
Now, to find y, plug-in x to any of the equations:
y = 2*2-1 = 3
Therefore, the solution to this system of equation is (2, 3)

Samuel can type nearly 40 words per minute. Use this information to find the number of hours it would take him to type 2.9 × 105 words.
Samuel can type 2.9 × 105 words in
hours and
minutes.
Answer:
Samuel can type 40 words per minute
Step-by-step explanation:.
Then how many hours will it take for him to type 2.6 words times 10 to the power of five words
=> 2.6 words time 10 to the power of 5
=> 2.6 x 10^5
=> 2.6 x 100 000
=> 260 000 words in all.
Now, we need to find the number of words Samuel can type in a hour
=> 40 words / minutes , in 1 hour there are 60 minutes
=> 40 x 60
=> 2 400 words /hour
Now, let’s divide the total of words he need to type to the number of words he can type in an hour
=> 260 000 / 2 400
=> 108.33 hours.

Answer:
the inverse of a function takes the output of the actual function as the input and gives the input of the initial function as the output
here, we are given that when we input 23 in the inverse function of 'f', we get 3
this means that if we input 3 in the initial function, we will get 23 as the output
f(x) = x² - ax + 8
changing the input value to 3
f(3) = (3)² - 3a + 8
changing the output value to 23
23 = 9 - 3a + 8
3a = 17 - 23
3a = -6
a = -2

Find the coordinates of the other endpoint of the segment, given its midpoint and one endpoint. (Hint: Let(x,y) be the unknown endpoint. Apply the midpoint formula,
and solve the two equations for x and y)
midpoint (-24.18) endpoint (-19.10)
The other endpoint is
(Type an ordered pair
M = ( (x1 + x2) / 2 , (y1 + y2) / 2 )
(9, 0) = ( (x1 + 12) / 2 , (y1 + 3) / 2)
Break up this formula into two equations.
(x1 + 12) / 2 = 9 and (y1 + 3) / 2 = 0
Solve for x1 and y1 from the equations.
another way to explain it
the formula for finding the midpoint of a segment given the coordinates of its endpoints is:
((x1+ x2)/2, (y1 + y2)/2 {Average of the x coordinates, average of the y coordinates}.
For this problem we know the coordinates of the midpoint along with one of the endpoints.
So the x coordinate of the midpoint (9) must equal (12 + x2)/2.
That is: 9 = (12 + x2)/2 Solve for x2. Follow a similar pattern to find the y coordinate of the unknown endpoint.
and another way
The x's are 3 apart and the y's are 3 apart. The other endpoint is (9 - 3, 0 - 3), or (6,-3).
hope this helped you have a good day this was ez
Toby gets 78 votes which is 52 percent how many voted in Tobys grade
Answer:
52% = 0.52
78/0.52 =150
150 students voted
Answer:
150
Step-by-step explanation:
When you multiply a number by a percentage you have to convert the percentage to a decimal so 52% turns into 0.52. If you multiply the number of votes by 0.52 it should equal to 78. In order to find the total number of votes. you have to go backwards and divide. So you divide 78 by 0.52 and it should give you 150.

The following sinusoid is plotted below. Complete the following steps to model the curve using the cosine function.
1.What is the phase shift, h, of this curve?
2.What is the vertical shift, k, of this curve?
3.What is the amplitude, a, of this curve?
4.What is the period and the frequency factor, b, of this curve?
5.Write an equation using the cosine function that models this data set.
Answer:
A.) phase shift is h=6
B.) Vertical shift is 21 units down
C.) The amplitude is 5 from the midline at y= -21
D.) The period is 16 and the frequency factor is pi/8
E.) 5 cos(pi/8(x-6))-21
Step-by-step explanation:
Find your minimum and maximum values. This would help you find the amplitude and the vertical shift. To find amplitude, the formula is A= (absolute value) of the max minus the min and divide by 2. To find vertical shift, you add the max and min values and divide by 2. The period is the distance of the max and min values and then doubled. The distance was 8 units so the period was 16. To find frequency factor, just plug in your values. You know that the formula is Period= 2pi/b. So it would be 16= 2pi/b. The frequency factor should be pi/8 after you cross multiply and then divide. To write the equation, you substitute the values into the equation of acos(b(x-c))+d. Make sure to put parentheses or else the graph will look wrong.

There is a parade coming through town, the route is 2 miles long with 10 foot wide sidewalks along each side. If the crowd is approximately 5 people per 16 square feet, how many people are estimated to be watching?
66 000 people
Step-by-step explanation:Hi there !
1 mile = 5280 feet
2 miles = 2×5280ft = 10 560 feet
Area = 2(10560ft×10ft) = 2×105600ft² = 211200 ft²
How many people are estimated to be watching?16 ft² ................ 5 people
211200 ft².........x people
x = 211200×5/16
= 1056000/16
= 66 000 people

It would look like this: 2y= -4x+6
Then, divide every term by two.
It would look like this: y=-2x+3

If the sum of three consecutive numbers is 852, what is the middle one?
it should be 3 and 3 is the the right answer
The required middle number is 284 and the three consecutive numbers would be 283, 284, and 285 respectively.
What is the number system?A number system is defined as a way to represent numbers on the number line using a set of symbols and approaches. These symbols, which are known as digits, are numbered 0 through 9. Based on the basic value of its digits, different types of number systems exist.
Let the three consecutive numbers would be x, x + 1, x + 2 respectively
Given that the sum of three consecutive numbers is 852
⇒ x + x + 1 + x + 2 = 852
⇒ 3x + 3 = 852
⇒ 3x = 852 - 3
⇒ 3x = 849
⇒ x = 849/3
⇒ x = 283
So the three consecutive numbers would be 283, 284, and 285 respectively.
Therefore, the required middle number is 284.

A customer purchased a lawn mower for a total purchase price of $318.75. If the state has a sales tax rate of 7.75%, what was the selling price of the lawn mower
Answer:
$343.45
Step-by-step explanation:
$318.75 x 1.0775 = $343.45
or
$318.75 x 0.0775 = $24.70
$318.75 + $24.70 = $343.45
The selling price of the lawn mower is $343.45 if the customer purchased a lawn mower for a total purchase price of $318.75.
What is percentage?It is defined as the ratio of two numbers expressed in the fraction of 100 parts. It is the measure to compare two data, the % sign is used to express the percentage.
We have a customer purchased a lawn mower for a total purchase price of $318.75.
Sales tax rate = 7.75%
Sales tax amount = 7.75% of $318.75
Sales tax amount = $24.64 ≈ $24.70
Original price = 318.75 + $24.70 = $343.45
Thus, the selling price of the lawn mower is $343.45 if the customer purchased a lawn mower for a total purchase price of $318.75.
