Answer:

Step-by-step explanation:

area of triangle + area of rectangle

1/2 * base * height + length * breadth

1/2 * 24 * 4 + 24 * 8

48 + 192

240

Answer:

240

Step-by-step explanation:

For the square, we multiply 8 * 24 and we get 192

The triangle, we first know the length overall for both the square and triangle is 12, but its cut off, so we subtract 12 from 8 because that is the lenght for the square and we get 4. However, remember that this is a triangle, so we divide 4 by 2, we get 2. Multiply 2 from the width fo the triangle which is 24 and we get 48. Sum it all up 192 + 48 and we get 240.

3. 51 inches

4. $213.11 each month

Step-by-step explanation:

1. Simplify both sides of the equation.

x + 7 + 7x= 25 + 6x

Combine Like Terms

(x + 7x) + (7)=6x + 25

8x + 7= 6x + 25

8x + 7= 6x + 25

Subtract 6x from both sides.

8x + 7 − 6x= 6x + 25 − 6x

2x + 7= 25

Subtract 7 from both sides.

2x + 7 − 7= 25 − 7

2x= 18

Divide both sides by 2.

2x/2= 18/2

2.  Subtract 5x from both sides.

x − 5x= 5x + 8 − 5x

−4x= 8

Divide both sides by -4.

−4x/−4= 8/−4

3. First find the perimeter of the trapezoid

4 + 3 + 4 + 8= 19

A square has all equal sides

8 * 4= 32

Add them together

19 + 32 = 51 inches

4. Subtract the amount she put for finance from the total

1598.66 - 320 = 1278.66

Then divide that amount by the 6 months

1278.66 divided by 6 = 213.11

$213.11 each month

The probability of being dealt 4 hearts from a standard 52 card deck if only 4 cards are to be dealt is 0.0026.

There are 52 cards in a standard deck, 13 of which are hearts.

We want to find the probability of getting dealt four hearts out of a four-card hand.

Since order doesn't matter, we will use combinations to calculate this probability.

P(A) = number of favorable outcomes / total number of possible outcomes.

There are 13 choose 4 ways to choose four hearts from the deck, and there are 52 choose 4 ways to choose any four cards from the deck.

So the probability of being dealt four hearts from a standard 52 card deck if only 4 cards are to be dealt is:

P(A) = (13 choose 4) / (52 choose 4)P(A)

       = (715) / (270725)P(A)

       = 0.002641056.

a) The structures have a major peak between 1700 and 3000 cm⁻¹ is carbonyl group

b) The typical stretching frequency of a carbonyl group is around 1710 cm⁻¹

Every bond has a characteristic frequency at which it vibrates, and this frequency is related to the strength of the bond. The stronger the bond, the higher the frequency of its vibration.

Now, let's talk about carbonyl groups. A carbonyl group is a functional group that consists of a carbon atom double-bonded to an oxygen atom. This functional group is found in many important molecules, such as ketones, aldehydes, and carboxylic acids.

When a carbonyl group vibrates, it produces a characteristic peak in the infrared spectrum between 1700 and 3000 cm⁻¹.

The stretching frequency of a bond is determined by the masses of the atoms in the bond and the strength of the bond.

For a carbonyl group, the stretching frequency is affected by the mass of the carbon and oxygen atoms, as well as the strength of the double bond between them.

When the (∂z/∂x) is 0, the partial derivative (∂z/∂y) will be equal to the total derivative dz/dy.

What is Total Derivative?

The overall change in the dependent variable as a result of changes in all the independent variables is known as the total derivative of a function of multiple variables.

Given that,

A function z(x, y)and its partial derivative (∂z/∂y) is x.

We know that,

total derivative (dz) = (∂z/∂x) dx + (∂z/∂y) dy

here, (∂z/∂y) = x

So, The dz will be equal to (∂z/∂y) dy only if  (∂z/∂x) dx = 0.

hence, (∂z/∂x) should be 0.

The calculated correlation coefficient (r) is approximately -0.291.

To calculate the correlation coefficient between telomere length and chronicity, we can utilize the given summary data. The correlation coefficient, often denoted as r, measures the strength and direction of the linear relationship between two variables.

Let's denote the sum of products as Σxy, the sum of squares for chronicity as Σx², the sum of squares for telomere length as Σy², and the total sample size as n.

From the given data, we have the following values:

Σxy = -8.822

Σx² = 318.817

Σy² = 2.868

n = 38

The correlation coefficient (r) can be calculated using the following formula:

r = Σxy / √(Σx² * Σy²)

Substituting the given values into the formula:

r = -8.822 / √(318.817 * 2.868)

Now, let's solve this equation step by step:

First, multiply the values inside the square root:

r = -8.822 / √(913.350956)

Next, calculate the square root:

r = -8.822 / 30.219307

Finally, divide Σxy by the square root of the product of Σx² and Σy²:

r ≈ -0.291

Answer:

Step-by-step explanation:

In this problem, we are given the circumference of a triangle (after finding the perimeter) and want to find the area of a circle with that circumference. Since the area of a circle is a function based on its radius, we can use the circumference to find the radius to find the area.

First, we can figure out the perimeter of the triangle, which is equal to the sum of its sides. The perimeter is 6+4+7.21 = 17.21 units.

Next, the circumference of a circle is equal to π * diameter = π * 2 * radius. Using 3.14 for π and r for radius, we get

3.14 * 2 * r = 17.21

6.28 * r = 17.21

divide both sides by 6.28 to isolate r

r ≈ 2.74

Furthermore, to find the area from the radius, we can use

area = πr². Plugging 2.74 in for r, we get

2.74² * 3.14 = area

≈23.6, rounding up to 24 units ²

The circumference is equal to the perimeter of the triangle. Then the area of the circle is 23.58 or 24 square units. Option B is correct.

It is a locus of a point drawn equidistant from the center. The distance from the center to the circumference is called the radius of the circle.

A triangle has sides that measure 4 units, 6 units, and 7.21 units.

Then the perimeter of the triangle will be

Perimeter = 6 + 4 + 7.21

Perimeter = 17.21

The circumference is equal to the perimeter of the triangle. Then the radius will be

\(2\pi r = 17.21\\\\r = 2.74\)

Then the area of the circle will be given as

\(\rm Area = \pi r^2 \\\\Area = \pi \times 2.74^2 \\\\Area = 23.58\)

Thus, the area of the circle is 23.58 square units.

50 quarts of sparking water and 25 quarts of grape juice are needed for 75 quarts of punch.

An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. The numerical relationship between two values demonstrates how frequently one value contains or is contained within another.

Given that a punch recipe calls for 1(¹/₂) quart of sparkling water and 3/4 of a quart of grape juice.

The ratio of sparkling water to grape juice is,

1(¹/₂) : (3/4 quarts) = (3/2) : (3/4) =  2 : 1

The amount sparkling water in the total volume is 2 : (2+1) = 2/3 of the total volume. For a volume of 100 quarts, the sparkling water content is

2/3 · 75quarts = 50 quarts

Then the grape juice content is,

1/3 · 75 quarts = 25 quarts

Therefore, 50 quarts of sparking water and 25 quarts of grape juice are needed for 75 quarts of punch.

The surface with the given vector equation, r(s, t) = (s cos(t), s sin(t), s), is a circular cone.

The vector equation r(s, t) = (s cos(t), s sin(t), s) represents a surface in three-dimensional space. Let's analyze the equation to determine the nature of the surface.

In the equation, we have three components: s, cos(t), and sin(t). The presence of s indicates that the surface expands or contracts radially from a central point. The trigonometric functions cos(t) and sin(t) determine the angle at which the surface extends in the x and y directions.

By observing the equation closely, we can see that as s increases, the radius of the surface expands uniformly in all directions, while the height remains constant. This behavior is characteristic of a circular cone. The circular base of the cone is defined by s cos(t) and s sin(t), and the vertical component is determined by s.

Therefore, the surface described by the vector equation r(s, t) = (s cos(t), s sin(t), s) is a circular cone.

Answer:

Yes you have enough money because with the dicound the crocs are $45.50

Step-by-step explanation:

u have $50 the crocs is $65 but have 30% off

$65 with 30% off is $45.50

Answer:

YAY, you can buy the Crocs!

Step-by-step explanation:

First we divide $65/100% to find one percent.

1% = 0.65

100% (original price) - 30% (sale) = 70% --> so the Crocs cost 70% their original price.

0.65 (1%) x 70 = $45.50 (final price of Crocs)
