Whitney drank a total of 2.15 liters of liquid.

Liquids are those substances that can flow or be poured, are incomprehensible, and are more rigid than gases.

From the given table we can say that the drinks Whitney takes over a day, which are juice, milk, and water, all come in the liquid category.

Therefore, the total amount of liquid that Whitney drinks today will be the sum of the volume of all of the above

which is 250 ml + 400 ml + 1,500 ml

=2,150 ml

For converting ml in liters we can divide the given volume by 1000 after which we get,

There are 11 observations in the subset data.e need to count the number of observations in the subset data.

1. First, we need to filter out the observations that have a date on or after May 1, 1975. For this, we can use the following code:

x3[x3$DATE >= "1975-05-01",]

2. Then, we need to count the number of observations in the subset data. We can do this by using the nrow() function:

nrow(x3[x3$DATE >= "1975-05-01",])

The output is 11.

If we wanted to subset the data set to include only observations that have a date on or before February 1, 1985, we can use the following code:

Answer:

Step-by-step explanation:

We can write the area of the rug as:

Area = 49x^2 - 25y^2

To find possible dimensions of the rug, we need to factor the expression on the right side. We can factor out 49 and 25 to get:

Area = 49 * x^2 - 25 * y^2

Area = 7 * 7 * x^2 - 5 * 5 * y^2

So, the area of the rug can be written as the product of two binomials, each of which represents one of the side lengths.

Therefore, one possible set of dimensions for the rug is 7x and 5y, and another possible set is -7x and -5y. Note that the dimensions are related in that the width of the rug is proportional to 7x, and the length is proportional to 5y.

To make the rug a square, the sides must be equal in length. To find the value that would need to be subtracted from the longer side and added to the shorter side, we take the difference between the two possible side lengths:

7x - 5y = (7x + 5y) - 2 * 5y = (7x + 5y) - 10y

So, to make the rug a square, you would need to subtract 10y from the longer side (7x) and add 10y to the shorter side (5y). This would result in both sides being equal to (7x + 5y)/2, making the rug a square.

a)  the number of sides = 24 sides (b) interior angle= 158.75° (c) sum of interior angles = 4080° (d) lines of symmetry = 12 (e) rotational symmetry of order  = 24.

a) To find the number of sides of a regular polygon given the value of its exterior angle, we use the formula:

360°/exterior angle = number of sides

So, for an exterior angle of 15°, we have:

360°/15° = 24 sides

b) To find the value of one interior angle, we use the formula:

interior angle = (number of sides - 2) * 180°/number of sides

So, for a polygon with 24 sides, we have:

interior angle = (24 - 2) * 180°/24

interior angle= 158.75°

c) The sum of the interior angles of a polygon with n sides is given by the formula:

sum of interior angles = (n - 2) * 180°

So, for a polygon with 24 sides, we have:

sum of interior angles = (24 - 2) * 180° = 4080°

d) To find the number of lines of symmetry of a regular polygon, we find the highest number of rotations that will produce the same figure. A regular polygon has n lines of symmetry if it can be divided into n equal parts by rotations of 360°/n.

So, for a regular polygon with 24 sides, we have:

lines of symmetry = 360°/interior angle = 360°/158.75° = 24/2 = 12

e) To find the order of rotational symmetry of a regular polygon, we find the number of rotations that will produce the same figure.

A regular polygon has rotational symmetry of order n if it can be divided into n equal parts by rotations of 360°/n.

So, for a regular polygon with 24 sides, we have:

rotational symmetry of order = 360°/exterior angle = 360°/15° = 24.

Let's call Akanksha's present age "x". After 42 years, her age will be "x + 42". And, as stated in the problem, her age after 42 years will be 4 times her present age, so:

x + 42 = 4x

Solving for x, we can isolate x on one side of the equation:

x + 42 = 4x

3x = 42

x = 14

So Akanksha's present age is 14 years old.

The value of ZE angle is 72 degree and LF is 18 degree.

Complementary and supplementary angles are defined as the addition of two angles. If the sum of two angles is 180 degrees, one is a complementary angle and together they form a linear angle. When the sum of two angles is 90 degrees, they are called complementary angles and together form a right angle.

ZE and LF are complementary. The measure of ZE is 54° more than the measure of LF.

let ZE angle value is x

and ZE is 54 degree more than LF

LF + 54 = ZE  degree  

When the sum of two angles is equal to 90 degrees, they are called complementary angles.

LF +ZE = 90 degree

x+x-54 = 90

2x = 36

x = 18

Incenter is the intersection of angle bisectors.

It means ST is angle bisector of ∠VSW, therefore:

a. The projectile will be at a height of 576 ft above the ground after 1.43 seconds and after 5.56 seconds.

b. The projectile will crash on the ground after 9.84 seconds.

The solution has been obtained by solving the equation.

What is an equation?

A mathematical equation is a formula that uses the equals symbol (=) to connect two expressions and express their equality.

We are given an equation as h = -16t² + v₀t + 448

Also v₀ is given as 112.

a. In order to find the time (t) the projectile will be at a height of 576 ft above the ground, we need to substitute h = 576 and v₀ = 112.

On substitution, we get

⇒h = -16t² + v₀t + 448

⇒576 = -16t² + 112t + 448

⇒36 = -t² + 7t + 28                (On dividing both sides by 16)

⇒0 = -t² + 7t - 8  

⇒t² - 7t + 8 = 0  

On solving the equation using the quadratic equation formula, we get

t = (7 ± √49 - 32)/2

t = 1.43 or 5.56

So, it will be at height 576 ft after 1.43 seconds and after 5.56 seconds.

b. Similarly, now we will put h = 0 and v₀ = 112.

Now, we get

⇒0 = -16t² + 112t + 448

⇒t² - 7t - 28 = 0                (On dividing both sides by 16)

On solving the equation using the quadratic equation formula, we get

t = (7 ± √49 + 112)/2

t = 9.84 or -2.84

Since, time cannot be negative, so it will crash after 9.84 seconds.

Hence, the projectile will be at 576 ft after 1.43 seconds and after 5.56 seconds and will crash on the ground after 9.84 seconds.

An equation that uses a unit fraction and a whole number to write a multiplication equation equal to 712 can be represented as:

712 = (1/N) * X

Where N is the unit fraction and X is the whole number. To find the values of N and X, we can isolate X on one side of the equation and divide both sides by (1/N):

X = (712 * N) / (1)

X = 712 * N

Now we can substitute the value 712 for the right side of the equation:

X = 712 * N

X = 712 / (1/N)

Finally, we can simplify the equation by dividing 712 by the reciprocal of N:

X = 712 * N

X = 712 / (1/N)

X = 712 * N / (1/N)

X = 712 * N * N

Now we have an equation in which X is equal to 712 times N times N. To find the values of N and X, we can use trial and error or other mathematical methods.

It is important to note that there may be multiple solutions to this equation, as there can be many unit fractions and whole numbers that multiply to equal 712. The goal is to find a combination of N and X that satisfies the equation and produces the desired result.

In conclusion, writing a multiplication equation equal to 712 using a unit fraction and a whole number is a common mathematical problem that can be solved by isolating the variable and dividing both sides by the unit fraction.

$89x = $668 - $490

$89x = $178

And finally, dividing both sides by $89:
