Answers

Answer 1

the correct question is
Ellie made a cube-shaped cardboard box with side-length s. The area of cardboard she used is given by the formula A = 6s2, where s represents the side length of the cube.

Which equation correctly solves the formula for s?

we know that
A = 6s²---------> clear the variable s
s²=A/6------> applying square root both members
s=√(A/6)--------> s=(1/6)*√(6*A)

the answer is
s=(1/6)*√(6*A)

Can somone help me with this 1 problem? In the figure shown, △RST is an isosceles triangle with RS≅RT. Which is the measure of ∠T?

A.21°

B.40°

C.70°

D.110°

Answers

In an isosceles triangle, the angles opposite to the two equal sides are also congruent.
Based on your information, T and S are congruent. So we know that the measure of angle T is 3x+7. But we need to solve for x. Let's add all the angle values together and set it to 180 because the angles of a triangle sum to 180.
1) 2(3x+7) + 2x - 2 = 180
2) 6x + 14 + 2x - 2 = 180
3) 8x + 12 = 180
4) 8x = 168
5) x = 21
6) m<T = 3x + 7 = 3(21) + 7 = 63 + 7 = 70
I got C, but it is always helpful to double check work. Hope this helps!

Final answer:

In an isosceles triangle, base angles are congruent, meaning ∠R would equal ∠T. However, no angle measures are provided, making it impossible to determine the measure of ∠T with the given information.

Explanation:

The given figure is an isosceles triangle, triangle RST, where RS is congruent to RT. In an isosceles triangle, the base angles are congruent, meaning that they have the same measure. Therefore, if we know the measure of one of the base angles, we know the measure of the other. The problem, however, does not provide the measures for any of the angles. This makes determining the measure of ∠T impossible with the given information. We would need to know either the measure of angle R or S or the measure of the angle at the vertex, angle T, to find the measure of ∠T. Without additional information, we cannot definitively choose between options A, B, C, or D.

The Freshman class has 27 more boys than girls. If there are 283 freshman, how many are girls?

Answers

You can write an equation to represent this situation. Let x represent the number of girls.

283 = x + (x + 27)

Here, we are adding the number of girls with 27 more people than this amount of girls. This will allow us to add the number of girls, x, with the number of boys, x + 27, to get a total of 283.

This equation can be simplified if we add the like terms together: the x's.

So,
283 = 2x + 27.

Since this is a multi-step equation, we must use the reversed order of operations; undo addition first.

283 - 27 = 2x + 27 - 27
256 = 2x + 0
256 = 2x

Now, we must undo multiplication by dividing.
256/2 = 2x/2
128 = 1x

So, x, the number of girls, is equal to 128.

Hope this helps you! :)

What is a circle?

The circle is defined as the locus of the point traces around a fixed point called the centre and is equidistant from the out trace.

The general form of the equation of the circle is given as:-

( x - h )² + ( y - k )² = r²

We have an equation:-

x² + y² - 6y + 1 = 0

x² + y² - 6y + 9 - 9 + 1 = 0

( x - 0 )² + ( y - 3 )² = 8

By comparing the equation from the standard form we will get the centre ( 0,3) and the radius r = 2√2.

Therefore the coordinates of the centre will be ( 0,3) and the length of the radius is equal to 2√2.

Four girls and eight boys are running for president or vice president of the student council. find each probability: find the prbability that two girls are elected

Answers

The probability is 1/11.

The probability that a girl is elected for one office is 4/12, since there are 4 girls out of 12 students.

The probability that a girl is elected for the second office is 3/11. This is because after one girl is elected, there are 3 girls left out of 11 students left.

Together, this gives us
4/12(3/11) = 12/132 = 1/11

The probability that two girls are elected president and vice president from a group of 4 girls and 8 boys is calculated using a hypergeometric distribution, resulting in a probability of 1/11.

The question is asking for the probability that two girls are elected president and vice president of the student council when there are four girls and eight boys running for these positions. This is an example of a hypergeometric distribution problem, as we are selecting without replacement from a finite population divided into two groups.

To find the probability, we need to determine the number of successful outcomes divided by the total number of possible outcomes. The successful outcome is that the two elected individuals are both girls. Since there are 4 girls, there are 4 choose 2 ways to select 2 girls, which equates to 6 possible successful outcomes. The total number of ways to choose 2 individuals from 12 candidates (4 girls + 8 boys) is 12 choose 2, resulting in 66 possible outcomes.

The probability can be calculated by dividing the number of successful outcomes by the total number of possible outcomes.

Probability = Successful outcomes / Total outcomes = 6 / 66 = 1 / 11

When the polynomial is written in standard form, what are the values of the leading coefficient and the constant? 5x + 2 - 3x^2

Answers

Leading coefficient = -3
Constant = 2

When you order them in standard form, you need to put them in ascending order of the exponents. Therefore the -3x^2 would come first, which makes the number attached (-3) the lead coefficient.

Also, since the number (2) without an x attached would be last (due to the power of x technically being 0), than that is the constant.

Consider this system of linear equations:

22x − y = -23 (equation 1)

11x + 12y = 1 (equation 2)

Answers

To solve this problem you must apply the proccedure shown below:

1. You have the folllowing system of equations given in the problem above:

22x − y = -23 (equation 1)
11x + 12y = 1 (equation 2)

2. If you multiply the equation 2 by -2, and then sum the equation 1+equation 2, you obtain:

-25y=-25
y=1

3. Then, you must substitute y=1 into the equation 1, then you have:

x=-1

4. As you can see, when you solve it, the solutions are:

x=-1
y=1

Using subtraction method or elimination method

22x − y = -23
-
(11x + 12y = 1) *2

22x − y = -23
-
22x + 24y = 2
0 -25y = -25
y = 1

22x - 1 = -23
x = 1

A silo is constructed using a cylinder with a hemisphere on top. The circumference of the hemisphere and the circumference of the cylinder are equal. The diameter of the circular base of the cylinder is 10 feet. The cylinder is 40 feet tall. One of the circular bases on the cylinder is in contact with the ground. What is the area of the surface of the silo that will be exposed to rain, wind, and sun?

Answers

Final answer:

The area of the surface of the silo that will be exposed to rain, wind, and sun is 450π square feet.

Explanation:

Solution:

To find the area of the surface of the silo that will be exposed to rain, wind, and sun, we need to find the combined surface area of the hemisphere and the cylinder.

The radius of the circular base of the cylinder is half of its diameter, which is 10/2 = 5 feet.The height of the cylinder is 40 feet.The circumference of both the hemisphere and the cylinder is equal, so the circumference of the circular base of the cylinder is 2πr, where r is the radius of the base.The surface area of the hemisphere is equal to half of the surface area of a sphere with the same radius, which is 2πr²/2 = πr².The surface area of the circular base of the cylinder is πr².The surface area of the curved surface of the cylinder is the circumference of the base multiplied by the height of the cylinder, which is 2πr * 40.

Now, let's calculate:

Surface area of the hemisphere = π(5)^2 = 25π square feetSurface area of the circular base of the cylinder = π(5)^2 = 25π square feetSurface area of the curved surface of the cylinder = 2π(5) * 40 = 400π square feet

To find the total surface area, we add up the surface areas of the hemisphere, the circular base, and the curved surface:

Total surface area = Surface area of hemisphere + Surface area of circular base + Surface area of curved surface = 25π + 25π + 400π = 450π square feet.

Therefore, the area of the surface of the silo that will be exposed to rain, wind, and sun is 450π square feet.

A cone and a pyramid have the same height and same volume. If the radius of the base of the cone is r, what is the side length of the square base of the pyramid?

Answers

let Vc : cone's volume, Vp : pyramid's Volume, r radius, h height. w width and l length.

Vc=πr²h/3

Vp=(lwh)/3

make it equal to each other and cancel out the 3.

πr²h = lwh

heights will cancel out

πr²=lw

l=(πr²)/w

To find the side length of the square base of a pyramid with the same volume and height as a cone with radius r, one can use the volume formulas V = (1/3)πr²h for a cone and V = (1/3)a²h for a pyramid. Setting them equal and solving for a yields a = r√π, indicating that the pyramid's base side length is the cone's radius times the square root of π.

The student is asking for the relationship between the dimensions of a cone and a pyramid that have the same volume and height. Specifically, if we have a cone with a radius r, and we want to find the side length of a square base of a pyramid that also has the same volume and height as the cone.

The volume of a cone is given by the formula [tex]V = (\frac{1}{3}) \pi r^2h[/tex], where radius of the cone's base is denoted by 'r' and the height is denoted by 'h'. For a pyramid with a square base, the volume formula is [tex]V = (\frac{1}{3} )a^2h[/tex], where a is the side length of the square base and h is again the height.

Given that both volumes are equal, we can set the formulas equal to each other and solve for a: [tex](\frac{1}{3} )\pi r^2h = (\frac{1}{3} )a^2h[/tex]. The heights cancel out, and we can simplify the equation to solve for the side length a: a = r√π. Therefore, the side length of the square base of the pyramid is the radius of the cone's base times the square root of π.

Solve the system of equations using the substitution method.

What is Equation Modelling?

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

Given is it costs $15 to roll a pair of dice and you get paid 2 dollars times the sum of the numbers that appear on the dice.

Assume that you get x and y value on dice 1 and dice 2 respectively. Then the equation representing the money recieved by a individual will be -

2(x + y)

The game will be fair if -

2(x + y) > 15

Now, for the sum of (x + y) = 7, the player will not have any profit. However, from (x + y) = 8, the players will start making profits. So, we can say it is a fair game, if your luck is not bad so far.

Therefore, we can conclude that, the money recieved by the player will be 2(x + y) and game is a fair game.
