Answer:
[tex]92.9\%[/tex]
Step-by-step explanation:
Initial amount of birdseed = 10.5 pounds
Final amount of birdseed = 12 ounces
[tex]1\ \text{ounce}=\dfrac{1}{16}\ \text{pounds}[/tex]
[tex]12\ \text{ounces}=\dfrac{12}{16}=0.75\ \text{pounds}[/tex]
Percentage change in the amount of birdseed is
[tex]\dfrac{\text{Initial-Final}}{\text{Initial}}\times 100\%=\dfrac{10.5-0.75}{10.5}\times 100\%\\ =92.9\%[/tex]
The percentage of birdseed that changed is [tex]92.9\%[/tex]
Plz help me solve this inequality! I’m timed!
Answer:
y > 1
General Formulas and Concepts:
Pre-Algebra
Equality PropertiesStep-by-step explanation:
Step 1: Define inequality
3(y - 2) + 4(3 - 2y) < 6(3y - 1) - 11y
Step 2: Solve for y
Distribute: 3y - 6 + 12 - 8y < 18y - 6 - 11yCombine like terms: -5y + 6 < 7y - 6Add 5y to both sides: 6 < 12y - 6Add 6 to both sides: 12 < 12yIsolate y: 1 < yRewrite: y > 1Here we see that any number y greater than 1 would work as a solution.

if f(x)=g(x)-10 and g(x)=3x-18 then what would the equation
represent f(x)
Hello!
[tex]\large\boxed{f(x) = 3x - 28}[/tex]
If f(x) = g(x)-10, substitute in the equation of g(x) to solve for f(x):
f(x) = (3x - 18) - 10
Simplify:
f(x) = 3x - 28

Step-by-step explanation:
What is the top one :(
Answer:
All answer below
Step-by-step explanation:
Equation of the Line
The standard form of the equation of a line is shown below:
Ax+By=C
And the slope-intercept form is:
y = mx + b
Where m is the slope and b is the y-intercept.
If we wanted to convert from the first form to the second we will perform the following operations:
Subtract Ax:
By = -Ax + C
Divide by B:
y = -A/Bx+C/B
The coefficient of x is -A/B (fill the blank with that text) and the y-intercept is C/B (again, fill in the blank)
The slope m is the coefficient of x, m=-A/B and it can be found it you divide the opposite of A by B. The selected option is correct.
The y-intercept is the division of C by B. Again, the selected option is correct.

slope-intercept form of Slope = -9/5, y-intercept = -4
Answer:
y = - [tex]\frac{9}{5}[/tex] x - 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - [tex]\frac{9}{5}[/tex] and c = - 4 , thus
y = - [tex]\frac{9}{5}[/tex] x - 4 ← equation of line

Find the length of side x in simplest radical form with a rational denominator.
Answer:
Step-by-step explanation:
given that both angles are the same, it is an equilateral right triangle.
we can use Pythagorean's theorem
[tex]a^2 + b^2 = c^2\\(\sqrt{6})^2+(\sqrt{6})^2= c^2\\ 12 = c^2 \\c = \sqrt{12} = \sqrt{4*3} = 2\sqrt{3}[/tex]
Time = 2hour +12 mins per lightswitch
She charges her customers a call out fee of £35, plus £30 per hour.
How much should a customer be charged for wiring a house with 10 lightswitch?
Answer:
£395
Step-by-step explanation:
call out fee = 35
30 per hour = 2 hour to be = 60
but, 12 minutes in hour = 12/60 = 0.2
0.2 = 0.2*30 = 6
2 hours and 12 minutes would be charges as
30 + 6 = 36
36*10 = 360
call out fee + per hour = 35 + 360 = 395
Write an equation of the line given an intercepts. Express in standard form.
1. x – intercept is 4 and y – intercept is 3.
2. x – intercept is -2 and y – intercept is 5.
Answer:
Required equations in standard form are:
1. 3x+4y=12
2. -5x+2y = 10
Step-by-step explanation:
Standard form of equation is given as:
[tex]Ax+By = C[/tex]
1. x – intercept is 4 and y – intercept is 3.
The points will be:
(4,0) and (0,3)
Slope: m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m = \frac{3-0}{0-4}\\m = -\frac{3}{4}[/tex]
Slope intercept form of line is:
[tex]y = mx+b[/tex]
Putting the values of m and b(y-intercept)
[tex]y = -\frac{3}{4}x+3[/tex]
Multiplying whole equation by 4
[tex]4y = -3x+12\\3x+4y = 12[/tex]
2. x – intercept is -2 and y – intercept is 5
The points will be:
(-2,0) and (0,5)
Now
[tex]m = \frac{5-0}{0+2}\\m = \frac{5}{2}[/tex]
Putting the values of m and b in slope intercept form
[tex]y = \frac{5}{2}x+5[/tex]
Multiplying the equation by 2
[tex]2y = 5x+10[/tex]
[tex]-5x+2y=10[/tex]
Hence,
Required equations in standard form are:
1. 3x+4y=12
2. -5x+2y = 10

A paper company needs to ship paper to a large printing business. The paper will be shipped in small boxes and large boxes. Each small box of paper weighs 35 pounds and each large box of paper weighs 65 pounds. There were 3 times as many small boxes shipped as large boxes shipped and the total weight of all boxes was 850 pounds. Determine the number of small boxes shipped and the number of large boxes shipped.
Answer:
15 small boxes and 5 big boxes
Step-by-step explanation:
5 x 3 = 15
15 x 35 = 525
5 x 65 = 325
525 + 325 = 850

The sum of three numbers is 107. The second number is 7 less than the first. The third number is 3 times the second. What are the numbers?
Answer:
27, 20, 60
Step-by-step explanation:
We use the equation
(x) + (x - 7) + (3 * (x - 7)) = 107
= x + x - 7 + 3 * (x - 7) = 107
= 2x - 7 + 3(x - 7) = 107
Add 7 on both sides
= 2x + 3(x - 7) = 114
Expand the 3
= 2x + 3x - 21 = 114
= 5x - 21 = 114
Add 21 on both sides
= 5x = 135
Divide 5 on both sides
= 5x/5 = 135/5
= x = 27
Plug the functions in
(27) + (27 - 7) + (3 * (27-7)) = 107
You would get
27 + 20 + 60 = 107, therefore the numbers are 27, 20, 60
Solve the formula for the specified variable.
W=X+Xyz for y
We have to isolate y.
W=X+Xyz
Subtract X from both sides. Doing so, we get the following: W - X = Xyz.
We now simply divide both sides by Xz to isolate y.
(W - X)/Xz = y
Done.
Find all points (x, y) where the functions f(x), g(x), h(x) have the same value: f(x) = 2^(x−5) + 3, g(x) = 2x − 5, h(x) = 8/x + 10
quickly please!!!!
Answer:
The point where f(x), g(x), and h(x) have the same value is (8, 11)
Step-by-step explanation:
The points where g(x) and h(x) have the same value is given as follows;
2x - 5 = 8/x + 10
2x² - 15x - 8 = 0
Using an online tool, we have;
(x - 8)(2x + 1) = 0
x = 8 or x = -1/2
∴ g(x) and h(x) = 11 or y = -6
For x = 8, we have;
f(x) = 2^(x - 5) + 3 = 2^(8 - 5) + 3 = 2^3 + 3 = 11
For x = -1/2, we have;
f(x) = 2^(-1/2 - 5) + 3 = 3.022
Therefore, the point where f(x), g(x), and h(x) have the same value is (8, 11), therefore, for x = 8, f(x) = g(x) = h(x) = 11.
