You can use ratios to solve the table

you know that for every 7 cups of sugar there are 4 cups of milk

The next column gives 14 cups of sugar but an unknown amount of milk

14 is 2 times 7, so the amount of milk would be 4 times 2, or 8 cups

The same logic can be applied for the rest

12 is 3 times 4, so the amount of sugar in column 3 would be 3 times 7

and so on and so forth

The percent error of the measurement, to the nearest tenth of a percent is: 1.4%.

Percent error can be described as the disparity between the value of what was estimated and the actual value, which is compared to the actual value as expressed in percentage.

The formula for calculating the percent error is:

Percent error = |measured value - actual value| / actual value × 100%.

We have the following given:

Actual length = 7.4 inches

Measured length = 7.3 inches

Therefore:

Percent error = |7.3 - 7.4| / 7.4 × 100%.

= 0.1/7.4 × 100

= 1.4%

To find the scale factor of dilation we need to know the coordinated and centre point of dilation

The scale factor of a dilation is a number that represents the relationship between the lengths of objects before and after the dilation. It is equal to the ratio of the lengths of corresponding sides after and before the dilation.

To find the scale factor of a dilation, it is required to know the coordinates of the two points that the dilation acts on. The scale factor is then given by the ratio of the distances between the two points after and before the dilation. We locate the centre of the dilatation, and then we measure the distances between this centre and various points on the preimage and the final image. Then the scale factor is determined by the ratio of these distances.

The two most vital body systems that are checked when performing the steps of checking the ABCs are the Circulatory and Respiratory Systems.

Blood veins in the circulatory system are responsible for moving blood away from and back toward the heart. Arteries carry blood out from the heart while veins carry it back. Oxygen, nutrients, and hormones are delivered to cells by the circulatory system, which also eliminates wastes like carbon dioxide.

The respiratory system refers to the network of tissues and organs in your body that facilitates breathing. It includes your lungs, blood vessels, and airways. The lungs' moving muscles are a part of the respiratory system. Together, these elements circulate oxygen throughout the body and remove waste gases like carbon dioxide.

Answer:

If a scatter plot shows a linear association, then there is a line that describes the relationship between the two measured quantities reasonably well. This means that there is a clear pattern in the data, and that the data points tend to follow a straight line when plotted on a graph. This does not necessarily mean that there is a line that passes through all of the plotted data points or that there is a tendency for relatively high values for one measured quantity to be paired with relatively high values for the other measured quantity.

The 100 feet per second rate at which rocket is rising vertically upwards and the 50 feet distance of the observation position from the launch, indicates;

A) The height of the rocket after exactly 2 seconds is 200 feet

B) The rate of the angular motion at which to scan upwards to keep track of the rocket is 2/17 radians per second

Angular motion is a circular motion of an object about a fixed axis, described in radians per second.

The rate at which the rocket is rising up in the air = 100 feet per second

The horizontal distance from the point of launch to the observer = 50 feet

The time at which the height of the rocket is required = 2 seconds

A) The height of the rocket after 2 seconds, h = 2 s × 100 ft/s = 200 ft

B) The angle of elevation of the line of sight to the rocket = θ

tan(θ) = h/50

sec²(θ)·(dθ/dt) = (1/50)·(dh/dt)

(dθ/dt) = (1/50) × (dh/dt)/sec²(θ)  = (1/50)×(dh/dt)×(cos²(θ))

At time, t = 2 seconds, the height of the rocket = 200 feet

Therefore;

tan(θ) = 200/50 = 4

θ = arctan(4)

dh/dt = The vertical velocity of the rocket = 100 ft/s

(dθ/dt) = (1/50)× 100 ×(cos²(arctan(4))) = 2/17

The cost of constructing the box will be = $81.77

Since the question gives us information about the rectangle,

so the area of the rectangle is shown by,

Area = 2 x (length + width)

So we have the area as,

Area = 2(lh + wh) +lw

(since the area per square meter is also given so we added l x w)

Since the cost of the base is = $5 per square meter and the cost of the sides is = $3 per square meter, so area in terms of the cost function,

⇒ C = 3 x 2(lh + wh) + 5 x l x w

⇒ C = 6(lh + wh) +5lw ---------equation 1

According to the question, the length of the rectangular container is twice that of the width of the container,

⇒ l = 2w

Substituting the new value of l in equation 1,

⇒ C = 6(2wh + wh) + 10 [tex]w^{2}[/tex]

⇒ C = 18wh + 10 [tex]w^{2}[/tex] ---------- equation 2

To calculate the volume of the rectangle,

V = length x width x height ( lwh )

substituting v = 10 and 2w = l,

2[tex]w^{2}[/tex]h = 10

h = [tex]\frac{5}{w^{2} }[/tex]

Substitute the value of h in equation 2,

⇒ C = 18w x [tex]\frac{5}{w^{2} }[/tex] + 10[tex]w^{2}[/tex]

⇒ C = [tex]\frac{90}{w}[/tex] + 10[tex]w^{2}[/tex] --------- equation 3

Differentiating the above equation we get,

⇒ C* = - [tex]\frac{90}{w^{2} }[/tex] + 20w

⇒ 20w = [tex]\frac{90}{w^{2} }[/tex]

Multiply both sides by [tex]w^{3}[/tex]

⇒ [tex]20w^{3}[/tex] = 90

⇒ [tex]w^{3}[/tex] = 4.5

w = 1.65

Put the value of w in equation 3,

⇒ C = [tex]\frac{90}{1.65}[/tex] + 10 x [tex]1.65^{2}[/tex]

⇒ C = 81.77

The term splitting is one of the methods used in factoring the quadratic expression.

We know that the general form of quadratic equation is ax² + bx + c = 0

The term splitting is one of the methods used in factoring the quadratic equation. When we can not square the first and the last term of the quadratic expression then we can use the method of splitting of the middle term. In this method we have to rewrite the middle term of the quadratic expression as the sum or difference of the two terms (the first and the last term).

For example, to factor a quadratic expression 4x² + 8x - 5

first find the product of the first and last term: 4 x (-5) = -20

Now, find the factors of -20 in such way that addition or subtraction of that factors is the middle term (8x) (Splitting of middle term):

10 x (-2) = -20 and 10 - 2 = 8

Now we write the quadratic expression using the sum of the two new factors, including the proper signs.  

4x² + 10x - 2x - 5

Now,factor each pair by finding common factors.  

2x( 2x + 5) - 1(2x + 5)

Now, factor out the common binomials.  

(2x - 1) ( 2x + 5)

Robinson's time is 25 minutes and Wrong' time is 40 minutes.

Equation of Time:

x + y = 65                  -------------------------- (1)

Total usage amount:

15x + 35y = 1775     -----------------------------(2)

There are several ways to answer this question. I will teach we how to create two equations from the given information. First we need to set some variables (or unknowns).  we need to set up a sprinkler time variable for each household. Let's call the time of the Robinson  family "x" and the time of the Wrong family "y". The total time used was 65, so the first formula is x + y = 65 ( Robinson's time plus Wrong's time gives total time).

Now,

We use the other hourly water information (remember we already have time variables for each family, x and y). We can set the following equation as 15x + 35y = 1775 (15 liters x the amount of time the Robinson's use water plus 35 liters x the amount of time the  use water gives equal to total usage).

Now,

We can solve for one of the variables (x or y). It doesn't matter which one we start with. Also, it doesn't matter which formula you start with. I used

x + y=65 . On the other hand, subtracting x gives y = 65 - x.

Now,

Replace y in the other formula. 15x + 35y = 1775 turns into

15x + 35(65-x) = 1775.

Distribute 35 to each term in brackets. By isolating the x variable: x=25

Recall that x means how long the Robinson's have been using sprinklers.

Now,

We can plug x into the other equation: 25 + y = 65

Therefore,

Subtract 25 on the other side to isolate y: y= 40

For instance, if three fruits, such as an apple, an orange, and a pear, are supplied, there are three possible pairings of the two: an apple and a pear. Formally speaking, a k-combination of a set S is a subset of S's k unique components. In other words, two combinations are the same if and only if they have the same members. (It is not important how the individuals in each set are arranged.) The number of k-combinations for a set with n components

The correct option is option C. $110

An out-of-pocket expense is an health expense incurred by an insured person, for which the insured person is not reimbursed.

The monthly premium for the family's health insurance plan = $55

The coverage offered by the health insurance for the first $600 = 90%

The coverage for prescription above $600 = 80%

The expected number of prescriptions by the family per month = 6

The total cost of the family's monthly prescription = $850

Therefore, the out-of-pocket expense by the family for one month are;

Out-of-pocket prescription for the first $600 = $600 - 90% × $600 = $60

Amount of prescription over $600 = $850 - $600 = $250
