100A + 20B + 200C = 36900  <---- $$$$

Byproducts are things created in a process, typically one that is industrial or biological, in addition to the main result. A byproduct of the sugar refining process is sulfured molasses.

the first two equations together:

10A + 8B + 20C = 6000

10A + 20B + 40C = 11000

first is subtracted from second: 12B + 20C = 5000 3B + 5C = 1250 —- identifies this equation. ALPHA

Connect the second and third equations:

10A + 20B + 40C = 11000

100A + 20B + 200C = 36900

The top equation is multiplied by 10:

100A + 200B + 400C = 110000 —— Weight restrictions

100A + 20B + 200C = 36900 <—— $$$$

takes them away:

180B + 200C = 73100

18B + 20C = 7310

9B + 10C = 3655 —- identifies this equation. ALPHA BETA: BETA: 9B + 10C = 3655 3B + 5C = 1250

ALPHA is multiplied by 3:

9B + 15C = 3750

9B + 10C = 3655

takes them away:

5C = 95\s C = 95/5 = 19

Plugging into BETA yields the following results: 9B + 10(19) = 3655 9B = 3655 - 190 B = 385

Answer:

(a) 2x + x + 39 = 90

(b) m<1 = 34°; m<2 = 56°

Step-by-step explanation:

Use the angle addition postulate. Angles 1 and 2 add to a right angle. A right angle has a measure of 90°.

(a) m<1 + m<2 = 90

2x + x + 39 = 90

(b)

Solve the equation for x.

2x + x + 39 = 90

3x = 51

x = 17

Use the value of x to find the angle measures.

m<1 = 2x = 2(17) = 34

m<2 = x + 39 = 17 + 39 = 56

Answer:

a.) 3x+39=90

b.) ∠1=34°

    ∠2=56°

Step-by-step explanation:

According to the graph, ∠1 + ∠2=90°.

∠1=2x and ∠2=x+39

So,

[tex]2x+(x+39)=90\\2x+x+39=90\\3x+39=90\\3x=51\\x=17[/tex]

Rewrite the equations for the two angles substituting 17 for x.

∠1=[2(17)]°=34° and ∠2=[(17)+39]°=56°

The number of hardcover books is 24 and the number of the softcover book is 36.

Here we have to find the number of hardcover and softcover.

Here it is given that 60 books are there.

Let x be the number of hardcovers, so the number of software books is 60- x.

The weight of each hardcover is 26 ounces and of softcover is 12 ounces.

The total weight is 1056 ounces.

So we get:

26x + ( 60 -x) 12 = 1056

26x - 12x + 720 = 1056

14x = 336

x = 24

60-x = 60 -24 = 36

Therefore the number of hardcovers is 24 and the number of softcovers is 36.

0.0912   is the probability that the score will be 120 or higher .

What is probability explain with an example?

Zlower = X₁ - μ/σ  = 120 - 100/15  = 1.33

the probability is compared as

                    Pr ( X ≥ 120 ) = Pr(X - 100/15 ≥ 120 - 100/15)

                                         = Pr(Z ≥ 120 - 100/15

                                          = Pr( Z ≥ 1.33)

A statement that explains whether 0.1515 is rational: Yes, because 0.1515 is a repeating decimal, so it can be expressed as a ratio of integers.

The correct answer is an option A

We need to select a correct statement that explains whether 0.1515 is rational.

We can observe that 0.1515 is the recurring decimal 0.15

This decimal can be written as a ratio of two integers.

Consider numerator = 5 and the denominator = 33.

So, 5/33 = 0.1515..

This means, 0.1515 can be expressed as p/q where p, q are integers with q ≠ 0

Therefore, a statement that explains whether 0.1515 is rational: Yes, because 0.1515 is a repeating decimal, so it can be expressed as a ratio of integers.

a. The equation in a point-slope form that represents distance as a function of time is  (y - 6)= (1/5)(x - 30).

b. The slope and y-intercept are (1/5) and 0 respectively.

c. In 4 hours I can bike for 40 miles.

We know lines have various types of equations, the general type is

Ax + By + c = 0, and the equation of a line in slope-intercept form is

y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.

We know the equation of a line in point-slope form is (y - y₁) = m(x - x₁).

Given, x represents time in minutes and y represents the distance in miles.

Let us take two ordered pairs (30, 6) and (40, 8).

Slope(m) = (y₂ - y₁)/(x₂ - x₁).

Slope(m) = (8 - 6)/(40 - 30).

Slope(m) = 2/10.

Slope(m) = 1/5.

∴ The equation of the line that represents distance as a function of time

is (y - 6)= (1/5)(x - 30).

Let y = mx + b.

6 = (1/5)30 + b.

6 = 6 + b.

b = 0.

So, y-intercept(b) = 0 and slope(m) is 1/5.

Expression simply refers to the mathematical statements which have at least two terms which are related by an operator and contain either numbers, variables, or both. Addition, subtraction, multiplication, and division are all possible mathematical operations. As an illustration, the expression x + y has the terms x and y with an addition operator between them.

The exponent is the number of times that a number is multiplied by itself. It should be noted that the power is an expression which shows the multiplication for the same number. For example, in 6⁴ , 4 is the exponent and 6⁴ is called 6 raise to the power of 4.

The area of the field is 4140 square yards.

A rectangle is a quadrilateral with all four interior angles 90°.

Given that, the perimeter of the field is 302 yards.

Let the length and width of the field be l and w respectively.

Given that, the length is 7 yards longer than three times its width, therefore,

l = 7 + 3w

The perimeter of the field is given by:

2(l +w) =302

l + w = 151

w = 151 - l..........(1)

Substitute l = 7+3w into the above equation:

w = 151 - 7 - 3w

w + 3w = 144

4w = 144

w = 36

Substitute w = 36 into equation (1):

36 = 151 - l

l = 151 - 36

l = 115

The area of the field is:

l × w

115 × 36

=4140

Hence, the area of the field is 4140 square yards.

Step-by-step explanation:

what does it mean for an object to stay at the same height ?

come on, you cannot tell me you don't understand this.

it means that e.g. the object is at a certain height (e.g. 50 ft above the ground) at the beginning of a time interval. then 1 seconds later it is still at the same height. 1 seconds after that it is still at this height. and so on.

how do you think that shows on a chart that displays height on an up or down scale ? as a flat (horizontal) line.

the chart is simply a rough picture of what the object does in real life.

so, where do we have flat (horizontal) segments in the curve ?

between second 2 and second 6.

and then infinitely after second 12.

in interval notation

[2, 6] and [12, +infinity)

please note the round bracket on the infinity side. it means the indicated end of the interval is not included. that is, because infinity is just a concept and not a number. it can never be reached. and it is therefore not included in the interval itself.

FYI - the flat line between second 2 and second 6 is not possible in real life, unless it rolls on a flat surface or something is holding it steady in place for these 4 seconds.

but a flying ball can never have a pure flat curve regarding height. only when it comes at rest on the ground. gravity would not allow that. not even for a bullet shot by a gun.

Scatterplot A; r = -0.42

Scatterplot B; r = -0.85

Scatterplot C; r = 0.64

Scatterplot D; r = 0.86

The correlation coefficient is defined as a statistical measure of the strength of a linear relationship that exists between two variables. Its' values can range from -1 to 1.

Now, a correlation is considered to be a positive correlation when both variables increases or decreases in tandem which is the same direction. Meanwhile, a negative correlation is defined as on whereby one variable increases as the other decreases.

Now, the farther away the data points are from each other the greater the value of the correlation coefficient and vice versa.

The scatterplot A is a negative correlation because the output increases as the input decreases and vice versa. This is more scattered than the other negative correlation; r = -0.42

The scatterplot B also has a stronger negative correlation than scatter plot A since r = -0.85

The scatterplot C has a positive correlation, but not so strong as seen by the spacing of the scatter dot points. Thus, the scatterplot C has a correlation coefficient of r = 0.64

The scatterplot D has a stronger positive correlation coefficient than C as seen in the dot scatter points and as such its' correlation coefficient is 0.86

The cold water faucet will fill the tub on its own in 5.6 minutes.

Let us assume the time taken by cold water faucet to fill the tub be x minutes. Now, the rate of hot water faucet to fill the tub = 1/14

Combined rate of filling by both faucets = 1/4

Rate of filling by hot water faucet + Rate of filling by cold water faucet = Rate of filling of tub by combination of two faucets

1/14 + 1/x = 1/4

1/x = 1/4 - 1/14
