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

Answer: 24
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

Answer: Joy sold 24 skeins of wool.

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!

Find f( - 4)/g( - 4)

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

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.

your table of values could look like this:

0.5

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.

The lower the standard error: Multiple Choice the more precisely the parameter estimates the true values. the less confident the manager can be that the parameter estimates reflect the true values. the less precisely the parameter estimates the true values. the more confident the manager can be that the parameter estimates reflect the true values.

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.

Answers

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

in a mixture of 20 litres,the pure milk is 60%,what quantity of water should be added so that pure milk becomes 40%?

Answers

Answer:

4 litres

Step-by-step explanation:

First, we are going to find 60% of 20 litres.

20 × [tex]\frac{60}{100}[/tex] = 12 litres

∴ Pure milk 12 litres.

Now we find 40% of 20 litres.

20 × [tex]\frac{40}{100}[/tex] = 8 litres

To find the quantity of water to be added we subtract the 8 litres from the 12 litres.

12 - 8 = 4 litres

∴ 4 litres of water should be added so that pure milk becomes 40%

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

Answers

Answer:

-1/2

Step-by-step explanation:

Perpendicular lines have negative reciprocal slopes.

The solution is, -1/2 is the slope of a line that is perpendicular to the line

shown on the graph.

What is slope?

In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).

here, we have,

we have to,

find the slope of the line shown using

the formula, m = y1- y2 / x1- x2

from the given graph we get,

Let

P1(0,1)

P2(1,3)

now we get,

replacing

m = 2/1

= 2

so, here, m1 = 2

two lines are perpendicular when

m1 * m2 = -1

as, we know that,

Perpendicular lines have negative reciprocal slopes.

so, we get ,

m2 = -1/2

Hence, The solution is, -1/2 is the slope of a line that is perpendicular to the line

shown on the graph.

201 tan 18=x

x=65.308858...

65.308858...+1.63= 66.938858...

≈ 66.9 meters tall

The height of the skyscrapers is 66.9 meters.

Given

From her eye, which stands 1.63 meters above the ground, Samantha measures the angle of elevation to the top of a prominent skyscraper to be 18°.

If she is standing at a horizontal distance of 201 meters from the base of the skyscraper,

The angle of elevation;

The angle of elevation of the sun is the angle formed between the horizontal line and your line of sight when you look at the sun.

Then,

The height of the skyscrapers is given by;

[tex]\rm Tan\theta=\dfrac{Opposite \ side}{Adjacent \ side}[/tex]

Substitute the values in the formula

[tex]\rm Tan\theta=\dfrac{Opposite \ side}{Adjacent \ side}\\\\\rm Tan18=\dfrac{x}{201}\\\\x = tan18\times 201\\\\x=65.30[/tex]

Therefore,

The height of the skyscraper is;

= 65.30 + 1.63 = 66.9

Hence, the height of the skyscrapers is 66.9 meters.
