The length of the movie screen at the local cinema is 37188552  feet.

Let's assume the width of the rectangle movie screen is represented by 'w' feet. According to the given information, the length of the screen is 303030 feet longer than the width. Therefore, the length can be expressed as 'w + 303030' feet.

The perimeter of a rectangle is given by the formula: 2(length + width). In this case, the perimeter of the movie screen is 148148148 feet. We can set up the equation as follows:

2(w + (w + 303030)) = 148148148.

Simplifying the equation, we have:

2(2w + 303030) = 148148148.

4w + 606060 = 148148148.

4w = 147542088.

Dividing both sides by 4, we get:

w = 36885522.

Therefore, the width of the screen is 36885522 feet. Since the length is 303030 feet longer than the width, we can calculate the length as:

Length = Width + 303030 = 36885522 + 303030 = 37188552 feet.

Hence, the length of the movie screen is 37188552  feet.

4 kilometers is the height of the given mountain.

In this case, we can consider the height of the mountain as the length of one side of a right triangle, the distance Ben climbed as the length of another side, and the distance from the base of the mountain to the center as the hypotenuse.

Let's denote the height of the mountain as h. According to the given information, the distance Ben climbed is 5 kilometers, and the distance from the base to the center of the mountain is 3 kilometers.

Using the Pythagorean theorem, we have the equation:

\(h^2 = 5^2 - 3^2\\\\h^2 = 25 - 9\\\\h^2 = 16\)

Taking the square root of both sides, we find:

h = √16

h = 4

Therefore, the height of the mountain is 4 kilometers.

Given:

Jenna's rent is increasing from $650 to $700 per month.

Increase every year = $50

Let's find the cost of the rent per month next 3 years.

The rent increases by $50 every year.

Given that the cost of the rent this year is $700, let's find the cost for the next 3 years.

To find the cost next 3 years per month, we have:

Cost next year = $700 + $50 = $750

Cost of rent next 2 years = $750 + $50 = $800

Cost of rent next 3 years = $800 + $50 = $850

Therefore, the costs of the rent 3 years from now are:

$750, $800, $850

What is Algebraic expression ?

Algebraic expression can be defined as the combination of variables , constants and exponents.

Let x be the number of minutes

And y be the number of pages.

y = 96 + x  --equation1 (for danielle )

y=39+4x --equation2 (for lorenzo)

By substituting equation 1 in equation 2.

we get,

96+x = 39 + 4x

96-39+x = 39-39+4x

57+x = 4x

4x-x = 57

3x = 57

x = 57/3

x = 19 .

Substitute x = 19 in equation 1 we get y = 96 + 19 and y=115

in equation 2 we get , y = 39 + 4*19

y = 39+76

y = 115

Hence , it took 19 minutes for each to read 115 pages.

Step-by-step explanation:

First, identify.

What do we know?

We know that she made 36 blueberry muffins.

We know that blueberry muffins are ONLY 40% of what she makes daily.

Now, to find whats missing, set up a proportion. I find it easiest to do this:

36 muffins         x muffins

---------------- = ------------------

40 %                     100%

To get from 40 to 100, multiply by 2.5. ( I got this by doing 100/40).

Now, to finish and solve for x, do the same for 36.

36*2.5=90

Correct Answer is D

Step-by-step explanation:

Notice how in D, there are no numbers that are able to be added into each other.

For example, in B, 6xy can be added into yx.

On solving the provided question, we can say that since it is a right angle x + (x-20) + 90 = 180 => x = 35

In Euclidean geometry, an angle is a shape made up of two rays, referred to as the angle's sides, that meet at a point in the middle known as the angle's vertex. Two rays can generate an angle that is in the plane where the rays are located. The meeting of two planes also creates an angle. They are referred to as dihedral angles. An angle is the shape created by two rays or lines that have a shared termination in plane geometry. The Latin word "angulus," which meaning "horn," is the source of the English term "angle." The vertex is the common terminal of the two rays, which are referred to as the sides of the angle.

difference between two of the angles is 20°.

since it is a right angle

x + (x-20) + 90 = 180

2x = 70

x = 35

Step-by-step explanation:

If one of the daughters marries a non-bald man and they have a son, the chance that the son will become bald as an adult is 0%

If the couple has a daughter, the chance that she will become bald as an adult is 0%

In the question, we have been given that the neither the father nor the mother is bald, and out of the four children only one son is bald, but the other son and the two daughters are not bald, now we solve the following:

Part a

A chance that the son will become bald as an adult:

If the daughter has no bald gene (XX), and she marries a non bald man then there is 0% chance that the son will become bald as an adult because neither the mom nor the dad has the baldness gene

Part b

The chance that she will become bald as an adult:

If the daughter having a bald gene (\(X^{b} X\)) marries a non bald (XY)man then also there is a 0% chance that the daughter will be bald as an adult. As the baldness is a recessive trait, for the daughter to be bald she needs to have two baldness gene( one from father and one from mother). And since this is not the case the daughter might have baldness gene but the phenotype will be non-bald.

An example of a commutative ring R with 1, a prime ideal P, and no zero divisors but R is not an integral domain is the ring R = Z/6Z, where Z is the set of integers and 6Z is the ideal generated by 6.

The ring R = Z/6Z consists of the residue classes of integers modulo 6. The elements of R are [0], [1], [2], [3], [4], and [5], where [a] denotes the residue class of a modulo 6.

In this ring, addition and multiplication are performed modulo 6. For example, [2] + [3] = [5] and [2] * [3] = [0].

R has a multiplicative identity, which is the residue class [1]. It is commutative since addition and multiplication are performed modulo 6.

The ideal P = 2R consists of the elements [0] and [2]. P is a prime ideal since R/P is an integral domain, which means there are no zero divisors in R/P. However, R itself is not an integral domain because [2] * [3] = [0] in R, showing that zero divisors exist in R.

Therefore, the ring R = Z/6Z, with the prime ideal P = 2R, satisfies the given conditions.
