The surface area of the triangular prism is 924 cm².

What is the triangular prism?

When a prism has three rectangular sides and two triangular bases, the prism is said to be triangular. A pentahedron, that is.

Volume is calculated using the formula volume = 0.5 * b * h * length, where b is the triangle's base length, h is its height, and length is the prism length.

                                         Area is defined as length * (a + b + c) + (2 * base area), where a, b, and c are the triangle's sides and base area is the triangle's base area.

The surface area is equal to the area of the two triangles + area of the three rectangles.

Area of two triangles:

12 × (9+5) × 1/2

= 84

84(2) = 168

Area of the three rectangles:

15 × 20 + 13 × 20 + 14 × 20

= 840

840 + 84

The surface area of the triangular prism is 924 cm².

-2/3,  is the slope of the line that passes.

A line's steepness and direction are measured by the line's slope.

Without actually using a compass, determining the slope of lines in a coordinate plane can assist in forecasting whether the lines are parallel, perpendicular, or none at all.

Any two different points on a line can be used to calculate the slope of any line.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively.

Two locations located on a straight line can be used to determine a line's slope. We can use the slope of line formula if we know the two spots' coordinates. These two points' coordinates should be-

P1 = (x1, y1) and P2 = (x2, y2)

According to our question-

Answer:

z = 56

Step-by-step explanation:

I'll assume 1.25/0.06 = z−6 /2.4 is actuallY:  1.25/0.06 = (z−6)/2.4  (and not 1.25/0.06 = z−(6 /2.4)).

1.25/0.06 = (z−6)/2.4

1.25*(2.4) = (z−6)*(0.06)  [Multiply both sides by 0.06 and then 2.4]

  3 =  0.06z - 0.36

3.36 =  0.06z

The answer to this Question based on Compound Interest is 1690.2$

What is Compound Interest?

Compound interest is a type of interest that is calculated not only on the initial principal but also on the accumulated interest of previous periods. It is the result of reinvesting interest, rather than paying it out, so that interest in the next period is then earned on the principal plus previously accumulated interest. It is the concept of earning interest on interest, which causes the total balance to grow at a faster rate than simple interest. Compound interest is often referred to as the eighth wonder of the world, as it is a powerful financial concept that can yield impressive results over a long period.

Initial money deposited = 900$
1$ turns into 1.878$ after 12 years of Compound Interest
hence by basic manipulation we can do like
900$ turns  into 900 multiplied by 1.878 which comes out to b 1690$
Hence after 12 years final amount will be 1690$

A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output. Four main categories can be used to classify different sorts of functions. One to one function, many to one function, onto function, one to one and into function—all based on the element. A relation between a domain and range is called a function when each value in the domain only has one value in the range.

The magnitude of length BC in the triangle ABC is equivalent to 8.49 units.

Pythagoras theorem states that -

"In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides“.

Mathematically, we can write-

[tex]a^2 + b^2 = c^2[/tex]

Given is that ABC is a right triangle, with right angle at B. Side AC has a length of 13 units. Side AB has a length of 5 units.

Using the Pythagoras theorem in the triangle ABC, we get -

AC² = BC² + AB²

BC² = AC² - AB²

BC² = (AC + AB)(AC - AB)

BC² = (13 + 5)(13 - 9)

BC² = 18 x 4

BC² = 72

BC = √(72)

BC = 8.49 units

Therefore, the length of the side BC is equivalent to 8.49 units.

In numbers, this looks like

1300/2000

Simplifying we get

13/20

If you use a calculator then you can input this equation. However, if you want to be big-brained you can use simple math to get the decimal answer fast.

13/20 = (13•5)/(20•5) = 65/100 = 0.65

But if you need a percent value then you are not done!

0.65 is not a percent. To get a percent you multiply your fraction or decimal by 100. Therefore we get 0.65•100 = 65%

65% of people would buy the car again. Therefore 65% of people are satisfied with that car.

B) 3 is the ratio of his speed and his car's fuel economy.

Velocity is the pace and direction of an object's movement, whereas speed is the time rate at which an object is traveling along a path. In other words, velocity is a vector, whereas speed is a scalar value.

[tex]\frac{speed}{fuel economy} =\frac{\frac{60 miles}{hour} }{\frac{20 miles}{gallon} } \\\frac{speed}{fuel economy}={\frac{60 miles}{hour} .{\frac{gallon}{20 miles} }\\[/tex]

Step-by-step explanation:

This equation only has 1 solution

Answer:

Step-by-step explanation:

To make F the subject of the formula, you need to solve for F in the equation C = 5(F-32)/9.

You can do this by first multiplying both sides of the equation by 9 to get rid of the fraction:

C * 9 = 5(F-32)

Then, you can distribute the 5 on the right side of the equation:

C * 9 = 5F - 160

Then, you can add 160 to both sides of the equation to isolate the F term:

C * 9 + 160 = 5F

Finally, you can divide both sides of the equation by 5 to solve for F:

F = (C * 9 + 160)/5

This gives you the final form of the equation:

F = (9C + 160)/5

In this form, F is the subject of the formula. a = 9, b = 160, and c = 5 are all positive integers.

Answer:

[tex]F=\dfrac{9C+160}{5}[/tex]

Step-by-step explanation:

Given equation:

[tex]C=\dfrac{5(F-32)}{9}[/tex]

Multiply both sides by 9:

[tex]\implies 9C=5(F-32)[/tex]

Divide both sides by 5:

[tex]\implies \dfrac{9C}{5}=F-32[/tex]

Add 32 to both sides:

[tex]\implies \dfrac{9C}{5}+32=F[/tex]

[tex]\implies F=\dfrac{9C}{5}+32[/tex]

Rewrite 32 as a fraction with denominator 5:

[tex]\implies F=\dfrac{9C}{5}+\dfrac{32 \cdot 5}{5}[/tex]

[tex]\implies F=\dfrac{9C}{5}+\dfrac{160}{5}[/tex]

[tex]\textsf{Apply the fraction rule} \quad \dfrac{a}{c}+\dfrac{b}{c}=\dfrac{a+b}{c}:[/tex]

The statement describes values of x and y such that x/y could be an irrational number is B. The value of x is the square root of an integer, and the value of y is an integer greater than zero.

The square root of an integer for x and a positive integer greater than zero for y are described in the statement as values of x and y that could be irrational numbers.

We have provided x and y values that could be irrational numbers. Any real number that cannot be expressed as the quotient of two integers is considered an irrational number. Positive whole numbers are not considered negative integers, nor are negative integers, or numbers below zero.

Consequently, we can say that A, C, or D do not demonstrate the irrational numbers since they are all expressed as integers.

For exa. measurement error, heights, IQ scores, and physical activity measures all follow the normal distribution.

In this question we need to describe why does the normal distribution have an importance in statistics of whether or not out appears in nature.

We know that if we plot the probability distribution and it forms a bell-shaped curve. If the mean, mode, and median of the sample are equal then the variable has normal distribution.

A normal distribution is dependent on two parameters of the data set: mean and the standard deviation of the sample.

This characteristic of the normal distribution makes it extremely simple.

Also, the normal distribution is important because of the Central limit theorem.

It makes math easy - like calculating moments, correlations between variables, and other calculations that are domain specific.

A balance sheet is a financial statement that lists the assets and liabilities of a corporation at a certain point in time. It is one of the three primary financial statements—the other two being the income statement and cash flow statement—that are used to assess a company's performance.

The weekly income is of $21,000, while a month is composed by four weeks, hence the monthly income is of:

=4 x $21,000

= $84,000.

Then the percentages of each expenses are applied to find the values, for example, 42% of that is for employee wages, hence:

= 0.42 x 84,000

= $ 35, 280

From the details we get Employee Wages 42% of $35,280.00

The measures of the angles are v = 80°, y = 100°, w = 45°, and x = 55°.

An inscribed four-sided polygon in a circle is known as a cyclic quadrilateral. With the specified side lengths, it has the largest area feasible.

Given the quadrilateral inside a circle.

The angle v is given by:

45° +v + 55°=180°

v + 100° = 180°

v = 180° - 100°

v = 80°

Since the quadrilateral is cyclic, the sum of its opposite angle is 180°.

Therefore,

y + v = 180°

y + 80° = 180°

y = 100°

Using the property of cyclic quadrilateral, it follows:

w = 45° and x = 55°

Hence, the measures of the angles are v = 80°, y = 100°, w = 45°, and x = 55°.
