Joy sells two types of yarn: wool and synthetic. Wool is $12 per skein and synthetic is $9 per skein. If Joy sold 16 skeins of synthetic and collected a total of $432, how many skeins of wool did she sell?
Answers
multiple the amount of synthetic skeins sold to the price of one synthetic skein. subtract the sum to the total. take the subtracted sum and divide it by the price of wool skeins
Explanation:
First you have to see how much of the money she has total came from the synthetic yarn profit.
If she sold 16 skeins of synthetic yarn you multiply 16 x 9(the price per skein of synthetic yarn) to get 144.
Next you subtract 144 from 432 (432-144) to get 288.
Finally, divide 288 by 12(the price of a skein of wool yarn) to get 24.
24 is the amount of skeins of wool yarn she sold.
To be sure you can multiply 24 x 12 (wool yarn sold) and add that to 16 x 9 (synthetic yarn sold) to get 432 which is your total profit.
Hope this helps!
Let f(x) = - 10x + 9 and g(x) = x2 + 12
Find f( - 4)/g( - 4)
Answers
Answer:
[tex]\frac{49}{28}[/tex]
Step-by-step explanation:
Evaluate g(- 4) and f(- 4) by substituting x = - 4 into g(x) and f(x), that is
f(- 4) = - 10(- 4) + 9 = 40 + 9 = 49
g(- 4) = (- 4)² + 12 = 16 + 12 = 28
Then
[tex]\frac{f(-4)}{g(-4)}[/tex] = [tex]\frac{49}{28}[/tex] = [tex]\frac{7}{4}[/tex]

4. What similarities do you see in the graphs?
5. What differences do you observe in the graphs?
6. What is the effect of changing the base on the graph of a logarithmic function?
Answers
Answer:
pls edit the question. there seems to be missing information. the function are not there.
in the meantime I hive you as much as possible.
I'll edit when you gave the missing functions.
your table of values could look like this:
x y1 y2
-2
-1
0
0.25
0.5
1
2
3
4
5
2. I did choose some negative integers, some positive and, as the problem requested, 2 values between 0 and 1. this should give some idea of the function when graphed.
3. calculate each scenario by swapping the x in the formula with the value for x from the table.
4. [need the functions for this one, but probably: one has a steeper slope than the other one]
5. [definitely need the graphs for this. I'll graph dem for you then]
6. the common logarithm is to the base 10. that means it answers questions like
[tex] {10}^{x} = 100[/tex]
this would be 2 for the example, so
[tex] log(100) = 2[/tex]
[tex] log_{10}(100) = 2[/tex]
these two are the same
if we change the base to, let's say, 8, it gives answers to problems like
[tex] {8}^{x} = 64[/tex]
this is relatively easy to see 2, so we can write it this way:
[tex] log_{8}(64) = 2[/tex]
Generally speaking, the log asks to wich power some base has to be raised to equal as certain value, like eight to the power of what equals 64.
which fraction have the greatest value 5/6, 1/6 -1/6, -5/6?
Answers
9514 1404 393
Answer:
(a) 5/6
Step-by-step explanation:
Positive numbers are greater than negative ones.
Fractions with the same denominator are greater if their numerator is greater.
All of these fractions have the same denominator. Because 5 > 1 > -1 > -5, the ordering of the fractions is ...
5/6 > 1/6 > -1/6 > -5/6
The fraction with the greatest value is 5/6.

Answers
Answer:
The more confident the manager can be that the parameter estimates reflect the true values.
Step-by-step explanation:
Standard error:
The standard error is a parameter that is direct proportional to the margin of error of a confidence interval, that is, the higher the standard error, the higher the margin of error of the confidence interval.
A lower margin of error leads to a more precise interval, thus, a lower standard error will also mean a higher confidence for the estimate, and thus, the correct option is:
The more confident the manager can be that the parameter estimates reflect the true values.

Answer:
x = 30
Step-by-step explanation:
The angle in the bottom right is 120
Call is y
y+60 = 180
y = 180-60
y =120
Opposite angles in a parallelogram are equal so the upper left angle is 120
Call the 3x +z = 120
We also know that 2x+90 +z = 180 since it forms a straight line
Subtract 90 from each side
2x+z = 90
Using 3x+z = 120 and 2x+z =90 and subtracting the second equation
3x+z = 120
-2x-z =-90

abby went to the movies and buy a large container of popcorn. The popcorn container can be modeled by a right circular cone with a diameter of 9 inches and a height of 10 inches. Popcorn has a density of 34 ounces per cubic foot. If a continer of popcorn costs $8, what is the price per ounce
Answers
Answer:
$1.918
Step-by-step explanation:
The volume of a right circular cone is obtained using the formular :
V = 1/3πr²h
From the question:
Diameter = 9 inches ; height = 10 inches
Radius = diameter /2 = 9/2 = 4.5 inches
V = 1/3*π*4.5²*10
V = 211.95 in³
Volume in ft³ = 211.95 / 1728 = 0.12265625 ft³
Density of popcorn = 34 ounces / ft³
Density of popcorn CONTAINER = x
1 ft³ = 34 ounce
0.12265625 ft³ = x
Cross multiply
x = 34 * 0.12265625 ft³
x = 4.1703125 ounce
Hence, popcorn continer has a density of 4.1703125 ounce
If price per container = $8
The price per ounce = $8 / 4.1703125
= $1.918
Hence, price per ounce is $1.918
