4. A bakery can make 58 packages of cookies
in one hour. There are 24 cookies in each
package. Which is the best estimate of the
number of cookies the bakery makes in one
hour.
a. 12,000
b. 120
c. 1,200
Show work to support your answer.
Answer:
C
Step-by-step explanation:
58*24=1392, which is closest to 1200.
Or, you could round the numbers to the nearest tens place, which would give you 60*20, giving you the exact answer of 1200. I think this was the preferred way of solving it.
Solve for x in 3 = (1/44)x
Answer:
132
Step-by-step explanation:
3 = 1/44x
÷1/44. - 1/44
= 132. = x
Answer:
x = 132
Step-by-step explanation:
3 = (1/44)x
3/(1/44) = (1/44)x/(1/44)
132 = x
The function h (x) = StartFraction 2 (x + 3) Over x EndFraction is a result of the composition (g compose f) (x). If g (x) = StartFraction 2 over x EndFraction, what is f(x)?
Answer:
[tex]f(x) = \frac{2x}{2x + 3}[/tex]
Step-by-step explanation:
Given
[tex]h(x) = \frac{2x + 3}{x}[/tex]
[tex]g(x) = \frac{2}{x}[/tex]
[tex]g(f(x)) = h(x)[/tex]
Required
Find f(x)
[tex]g(x) = \frac{2}{x}[/tex]
Substitute x for f(x)
[tex]g(f(x)) = \frac{2}{f(x)}[/tex]
Recall that
[tex]g(f(x)) = h(x)[/tex]
This gives
[tex]\frac{2}{f(x)} = \frac{2x + 3}{x}[/tex]
Cross Multiply
[tex]f(x) * (2x + 3) = 2 * x[/tex]
[tex]f(x) * (2x + 3) = 2 x[/tex]
Make f(x) the subject of formula
[tex]f(x) = \frac{2x}{2x + 3}[/tex]
Answer:
x/x+3

f(x) = 4x - 3
g(x) = 3x - 1
Find (fºg)(x)
Answer:
0.5 or -0.5
Step-by-step explanation:
4x - 3 = 3x - 1
-1 + 3 = 2
4x = 3x - 2
4 - 3 = 1
1x = -2 or positive 2
1x ÷ -2
-0.5 or 0.5
-----‐------------------------
4x-3 = 1
3x -1 = 0.5
f= 1
g= 0.5
1 x 0.5 = x
x= 0.5
DVDs are on sale for $29 each. Felipe writes the expression 2 x 29 to find the cost in dollars of buying 2
DVDs
How can you rewrite Felipe's expression using the Distributive Property?
Answer:

Use linear approximation to approximate √25.3 as follows.
Let f(x)=√x. The equation of the tangent line to f(x) at x=25 can be written in the form y=mx+b. Compute m,b.
Using this, find the approximation for √25.3.
The idea is to use the tangent line to [tex]f(x)=\sqrt x[/tex] at [tex]x=25[/tex] in order to approximate [tex]f(25.3)=\sqrt{25.3}[/tex].
We have
[tex]f(x)=\sqrt x\implies f(25)=\sqrt{25}=5[/tex]
[tex]f'(x)=\dfrac1{2\sqrt x}\implies f'(25)=\dfrac1{10}[/tex]
so the linear approximation to [tex]f(x)[/tex] is
[tex]L(x)=f(5)+f'(5)(x-5)=5+\dfrac{x-5}{10}=\dfrac x{10}+\dfrac92[/tex]
Hence [tex]m=\frac1{10}[/tex] and [tex]b=\frac92[/tex].
Then
[tex]f(25.3)\approx L(25.3)=\dfrac{25.3}{10}+\dfrac92=\boxed{7.03}[/tex]
A certain number of sixes and nines is added to give a sum of 126; if the number of sixes and nines is interchanged, the new sum is 114. How many of each were there originally?
Answer:
Original number of sixes = 6
Original number of nines = 10
Step-by-step explanation:
We are told in the question that:
A certain number of sixes and nines is added to give a sum of 126
Let us represent originally
the number of sixes = a
the number of nines = b
Hence:
6 × a + 9 × b = 126
6a + 9b = 126.....Equation 1
If the number of sixes and nines is interchanged, the new sum is 114.
For this second part, because it is interchanged,
Let us represent
the number of sixes = b
the number of nines = a
6 × b + 9 × a = 114
6b + 9a = 114.......Equation 2
9a + 6b = 114 .......Equation 2
6a + 9b = 126.....Equation 1
9a + 6b = 114 .......Equation 2
We solve using Elimination method
Multiply Equation 1 by the coefficient of a in Equation 2
Multiply Equation 2 by the coefficient of a in Equation 1
6a + 9b = 126.....Equation 1 × 9
9a + 6b = 114 .......Equation 2 × 6
54a + 81b = 1134 ........ Equation 3
54a + 36b = 684.........Equation 4
Subtract Equation 4 from Equation 3
= 45b = 450
divide both sides by b
45b/45 = 450/45
b = 10
Therefore, since the original the number of nines = b,
Original number of nines = 10
Also, to find the original number of sixes = a
We substitute 10 for b in Equation 1
6a + 9b = 126.....Equation 1
6a + 9 × 10 = 126
6a + 90 = 126
6a = 126 - 90
6a = 36
a = 36/6
a = 6
Therefore, the original number of sixes is 6
The second statement is the

Given the function h (x) = 2x + 4, for which value of x does h (x) = 18?
The required value for which h(x) = 18 is given as x = 7.
What are functions?Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
Here,
The function h(x) = 2x + 4 - - - - (1)
Since h(x) =18
Substitute h(x) = 18 in equation 1,
18 = 2x + 4
Simplify
18 - 4 = 2x
x = 14 / 2
x = 7
Thus, the required value for which h(x) = 18 is given as x = 7.

A. 70.5%
B. 89.5%
C. 50%
D. 29.5%

A
Step-by-step explanation:
Are the following lines parallel, perpendicular, or neither: x=6 and x=12 Please show work or explain
Answer:
x=6 and x=12 are parallel.
Step-by-step explanation:
If you graph x=6 it will be a straight verticle line on the x-axis where 6 is, same with x=12 (put a vertical line on 12 for the x-axis). When you put these both on the same graph you see they are directly across from each other but will never touch. Therefore, they are parallel. If you are writing this on paper, simply draw a graph to show this.
