A bakery uses a muffin recipe that uses 1/2 cup of milk for every batch of 12 muffins...... Select Each Correct Answer............
A.(1/24 cup of milk is used to make each muffin.)....B(.1/24 cup of milk is used to make each muffin) C.(1/6 cup of milk is used to make each muffin.) D.(1 cup of milk is used to make each muffin). E. (1 cup of milk is used to make every 12 muffins). F.( 1 cup of milk is used to make every 24 muffins)
(1/2)/12=1/24. So A is correct. There is no difference between A and B... F is also correct....we multiply 12 by 2 to get 1 cup per 24 muffins.

For each equation, find a value for x that makes the equation true. Show your work on the next
page.
a.
x=3 = 12
b.
2x + 3 = 20
4
10
C.
d.
- 4x = -24
e.
2(x – 4) = 10
-0.5x + 1.1 = -2.9
f.
Answer:
A.) x / 3 = 12 ----> x = 12(3) ----> x = 36
B.) 2x + 3 = 20 ----> 2x = 17 ----> x = 17/2
C.) 4/3x = 10/3 ----> x = 10/3 x 3/4 ----> x = 30/12 = 5/2
D.) -4x = -24 ----> x = -24/-4 ----> x = 6
E.) 2(x-4) = 10 ----> 2x - 8 = 10 ----> 2x = 18 ----> x = 9
F.) -0.5x + 1.1 = -2.9 ----> -0.5x = -4 ---> x = -4 / -0.5 ----> x = 8

Answer:
-6
Step-by-step explanation:
because the roots are the x values of where the function crosses the x axis
so thats at -2 and 3
and product is multiplication
so -2×3= -6
Answer:
The roots/zeroes are where the x-values where the graph touches or passes through the x-axis..They are at -1 and 3. So your answer would be a) -1

Is 5.1 times 10 to the power of 9 a scientific notation?
Answer:
yes
Step-by-step explanation:
hope it helps
it will be written as 5.1×10^9
Answer:
yes
Step-by-step explanation:
A number in scientific notation consists of the product of a number from 1 to under 10 and an integer power of 10.
5.1 is a number from 1 to under 10.
10^9 is an integer power of 10.
Therefore, 5.1 * 10^9 is a number written in scientific notation.
What is the answer to this question
Answer:
C
Step-by-step explanation:
Lines that are parallel AND have different y-intercepts will never intersect each other, therefore will have no solutions.
The only correct choice is C as the lines are parallel and have different y-intercepts which means they'll never intersect each other. All the other choices will have their lines intersect each other at some point.

A) 64
B) 128
C) 8
D) 4
Answer:
the anser is 64 cups
Step-by-step explanation:

pls mark brainliest
Answer:
A. 64 cups
Step-by-step explanation:
There are 16 cups per gallon, so a half gallon would be 8 cups. If she bought 8 bottles that means you must take the 8 bottles times the 8 cups per bottle or just 8*8=64. Answer A. is 64 cups.

2.) Find the vertex only for the following function:
y = -3x^2 + 12x - 5
Answer:
(2, 7)
Step-by-step explanation:
hope this helps :)
( 1 ) Find by using a formula of (-b/2a, (4ac-b²)/4a)
[tex](\frac{-b}{2a},\frac{4ac-b^2}{4a})\\(\frac{-12}{2(-3)}),(\frac{4(-3)(-5)-(12)^2}{4(-3)})\\(\frac{-12}{-6}),(\frac{60-144}{-12})\\(2,\frac{-84}{-12})\\(2,7)[/tex]
The vertex is at (2,7)
( 2 ) Find by using a derivative (Calculus)
You can also find a vertex by using a calculus. Using a derivative
[tex]y'=-3x^2+12x-5\\y'=-6x+12\\\\[/tex]
Then substitute y' = 0 to get a vertex.
[tex]y'=-6x+12\\0=-6x+12\\-12=-6x\\2=x[/tex]
Then substitute x = 2 in the equation of y = -3x²+12x-5
[tex]y=-3x^2+12x-5\\y=-3(2)^2+12(2)-5\\y=-3(4)+24-5\\y=-12+24-5\\y=-17+24\\y=7[/tex]
x = 2 and y = 7, therefore. The vertex is (2,7)

Answer:
[tex]f^{-1}(x) = x/2 +2[/tex]
Step-by-step explanation:
let [tex]f^{-1} (x)[/tex] = y
then f(y) = x
2y-4 =x
2y =x+4
y= x/2 +2
hence f^{-1} (x) = x/2 +2

Simone claims that the slope of the line through (-2, 7) and (3, 0) is the same as the slope of the line through (2, 1) and (12, -13) is simone's claim true or false
Answer:
Simone is correct
Step-by-step explanation:
Given
Line 1:
[tex](x_1,y_1) = (-2, 7)[/tex]
[tex](x_2,y_2) = (3, 0)[/tex]
Line 2:
[tex](x_1,y_1) = (2, 1)[/tex]
[tex](x_2,y_2) =(12, -13)[/tex]
Required
Is Simone correct?
Slope (m) is calculated using:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
For Line 1
[tex]m = \frac{0 - 7}{3 - (-2)}[/tex]
[tex]m = \frac{0 - 7}{3 +2}[/tex]
[tex]m = \frac{-7}{5}[/tex]
[tex]m = -\frac{7}{5}[/tex]
For Line 2:
[tex]m = \frac{-13 - 1}{12 -2}[/tex]
[tex]m = \frac{-14}{10}[/tex]
Divide by 2/2
[tex]m = \frac{-14/2}{10/2}[/tex]
[tex]m = \frac{-7}{5}[/tex]
[tex]m = -\frac{7}{5}[/tex]
By comparison, both lines have the same slope.
Hence, Simone is correct

Jeremy find the cost by adding the percents. 25% off of $60 is equal to 15% off of $60, then subtracting 10% from that cost is equal to . The two total costs are
Answer:
a. 25% off of $60 is equal to $45.
b. 15% off of $60, then subtracting 10% from that cost is equal to $45.
c. The two total costs are $45 and $45, and their addition is equal to $90 (i.e. $45 + $45 = $90).
Step-by-step explanation:
These can be determined as follows:
a. Calculation of the first total cost, i.e. 25% off of $60
25% of 60 = 25% * $60 = 15
First total cost = 25% off of $60 = $60 - (25% of $60) = $60 - $15 = $45
Therefore, 25% off of $60 is equal to $45.
b. Calculation of the second total cost, i.e. 15% off of $60, then subtracting 10% from that cost
15% of $60 = $9
10% of $60 = $6
Cost = 15% off of $60 = $60 - (15% of $60) = $60 - $9 = $51
Second total cost = Cost - (10% of $60) = $51 - $6 = $45
Therefore, 15% off of $60, then subtracting 10% from that cost is equal to $45.
c. The two total costs
The two total costs are 25% off of $60 which is equal to $45 and 15% off of $60, then subtracting 10% from that cost which is also equal to $45. The addition of the two costs is $90 (i.e. $45 + $45 = $90).
Therefore, the two total costs are $45 and $45, and their addition is equal to $90 (i.e. $45 + $45 = $90).
