Answer:
5,743 people
Step-by-step explanation:
Number of people that came to hear the concert on saturday = 2684 people
If on Sunday, 375 more people came to the concert than Saturday, the the total number of people that cam on sunday = 375+2684 = 3059 people
The total number of people who came to hear the concert last weekend will be expressed as;
= People that came on saturday + those that came in sunday
= 2684 + 3059
= 5,743 people

Write a linear function with the values f(0) = 5 and f(-3) = 6
Answer:
You are given two points, (0,6) and (3,-3), so use the two-point formula for the equation of a line:
y - y1 = ( (y2 - y1) / (x2 - x1) ) (x - x1)
y - 6 = ( -9 / 3 ) (x - 0)
y - 6 = -3x
y = -3x + 6 This is: y = mx+b
Step-by-step explanation:
hope this will help you..
The linear function with the values f(0) = 5 and f(-3) = 6 is [tex]y=\frac{-1}{3}x+5[/tex]
The given functions are:
f(0) = 5
f(-3) = 6
That is, x₁ = 0, y₁ = 5, x₂ = -3, y₂ = 6
The slope of the linear function is calculated as:
[tex]m=\frac{y_2-y_1}{x_2-x_1} \\\\m=\frac{6-5}{-3-0} \\\\m=\frac{-1}{3}[/tex]
The equation of a line is given as:
[tex]y-y_1=m(x-x_1)[/tex]
[tex]y-5=\frac{-1}{3}(x-0)\\\\y-5= \frac{-1}{3}x\\\\y=\frac{-1}{3}x+5[/tex]
The linear function with the values f(0) = 5 and f(-3) = 6 is [tex]y=\frac{-1}{3}x+5[/tex]

Jessica reads aloud from science website. She comes across the mesurement 0.32 meter. How shouls she read this mesurement aloud? Explain how you know
Answer:
zero point three two meter
Step-by-step explanation:
Given
[tex]Measurement = 0.32\ meter[/tex]
Required
How should it be pronounced
From the measurement above, we can see that it contains a decimal point.
Using the rules of decimal point,
The number before the decimal point will be treated as 1 number and will be pronounced as such.
While numbers after the decimal will be treated as individual digits and will be pronounced individually.
Hence, the pronunciation of 0.32 meter is zero point three two meter

The area of a circle is given by the formula:
A = Ttr2 where r is the radius of the circle.
What is the exact area of a circle with a diameter of 10 cm?
Answer:
A = 25π cm²
Step-by-step explanation:
The area (A) of a circle is calculated as
A = πr² ( where r is the radius )
Here diameter = 10, thus r = 10 ÷ 2 = 5, then
A = π × 5² = 25π cm²
Walter and Helen are asked to paint a house. Walter can paint the house by himself
in 12 hours and Helen can paint the house by herself in 16 hours. How long would it
take to paint the house if they worked together? Round to the nearest tenth.
The division is one of the four fundamental arithmetic operations. The time it will take both of them together to paint the house is 6.857 hours.
What is Division?The division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.
Let the area that is needed to be painted be x.
Given that Walter can paint the house by himself in 12 hours. Therefore, we can write the rate at which Water paint is,
Rate = Area needed to be painted / Time
= x / 12 hours
= x/12
Further, given that Helen can paint the house by herself in 16 hours. Therefore, we can write the rate at which Helen paint is,
Rate = Area needed to be painted / Time
= x / 16 hours
= x/16
Now, the rate at which they both will paint or the area that they will cover in an hour is,
Rate = (x/12) + (x/16)
= (4x/48) + (3x/48)
= (4x + 3x)/48
= 7x / 48
Furthermore, the time it will take both of them together to paint the house is,
Time = Area needed to be painted / Rate
= x / (7x/48)
= 48/7 hours
= 6.857 hours
Hence, the time it will take both of them together to paint the house is 6.857 hours.

y = 2x + 6. If x = 5, how much is y?
Answer:
16
Step-by-step explanation:
Y=2(5)+6
y=10+6
Y=16
please answer a and c pwease
Answer:
Let's identify what we know and what we are looking for. To start off, the question states that there is a flat rate of 500. This is the y intercept, because you start off with 500. It also states that it charges a fee of 50 per hour, which is your slope. So what we have now is y=50x+500. We know that A is asking how much it will be for 20 hours. We simply plug 20 into x, so we do y=50(20)+500 which gives 1500. For C, we repeat the same step and just plug in 50.

Answer: [tex]1\dfrac13[/tex] cups of pineapple juice .
Step-by-step explanation:
Equation of direct proportion between x and y:
[tex]\dfrac{x_1}{y_1}=\dfrac{x_2}{y_2}[/tex]
As per given,
Let x = quantity of pineapple juice and y = quantity of orange juice.
[tex]x_1=\dfrac13\[/tex] , [tex]y_1=\dfrac34[/tex] , [tex]y_2=3[/tex]
Put these values in an equation we get
[tex]\dfrac{\dfrac13}{\dfrac34}=\dfrac{x_2}{3}\\\\\Rightarrow\ \dfrac{4}{9}=\dfrac{x_2}{3}\\\\\Rightarrow\ x_2=3\times\dfrac{4}{9}=\dfrac{4}{3}\\\\\Rightarrow\ x_2=1\dfrac13[/tex]
Hence, he needs [tex]1\dfrac13[/tex] cups of pineapple juice .
Answer:
He needs 1 and 1/3 cups of pinapple juice when he uses 3 cups of orange juice.

The radius of the base of a cylinder is decreasing at a rate of 9 millimeters per hour and the height of the cylinder is increasing at a rate of 2 millimeters per hour. At a certain instant, the base radius is 8 millimeters and the height is 3 millimeters. What is the rate of change of the surface area of the cylinder at that instant in square millimeters per hour?
a) 310pi
b) 155pi
c) -155pi
d) -310pi
Answer:
Answer: d) -310pi
Step-by-step explanation:
Instantaneous Rate of Change
Is the change in the rate of change of a function at a particular instant. It's the same as the derivative value at a specific point.
The surface area of a cylinder of radius r and height h is:
[tex]A=2\pi r^2+2\pi r h[/tex]
We need to calculate the rate of change of the surface area of the cylinder at a specific moment where:
The radius is r=8 mm
The height is h=3 mm
The radius changes at r'=-9 mm/hr
The height changes at h'=+2 mm/hr
Find the derivative of A with respect to time:
[tex]A'=2\pi (r^2)'+2\pi (r h)'[/tex]
[tex]A'=2\pi 2rr'+2\pi (r' h+rh')[/tex]
Substituting the values:
[tex]A'=2\pi 2(8)(-9)+2\pi ((-9) (3)+(8)(2))[/tex]
Calculating:
[tex]A'=-288\pi +2\pi (-27+16)[/tex]
[tex]A'=-288\pi +2\pi (-11)[/tex]
[tex]A'=-288\pi -22\pi[/tex]
[tex]A'=-310\pi[/tex]
Answer: d) -310pi

Answer:
4. 3
Step-by-step explanation:
If you multiply 2 by 3 it'll equal to 6. Same with 7 x 3= 21.
You could also subtract 7 from 2 equalling 5 and 21 - 6 equal to 15. Then you would but y over x giving you 15/5. 15 divided by 5 is 3. So both ways you get 3.

Wells College in Aurora, New York was previously an all-girls college. In 2005, the college began to allow boys to enroll. By 2012, the ratio of boys to girls was 3 to 7. If there were 200 more girls than boys in2012, how many boys were enrolled that year?
Answer:
150 boys were enrolled in 2012
Step-by-step explanation:
Let the number of boys enrolled in 2012 be x
Let the number of girls enrolled in 2012 be x + 200
Ratio of boys to girls in 2012 enrollment = 3/7
Now;
3/7 = x/x + 200
7x = 3(x + 200)
7x = 3x + 600
7x - 3x = 600
4x = 600
x = 600/4
x = 150 boys
Hence, 150 boys were enrolled in 2012

Step-by-step explanation:
Adriana needs to send 232 invitations to her family and friends for her party.
There are 12 invitations in a box.
We need to find how many boxes will Adriana needs to order so that everyone receives an invitation. Let there are x boxes. It can be calculated as :
[tex]x=\dfrac{232}{12}\\\\x=19.34[/tex]
or
x = 19
So, she will need approx 19 boxes.
