x + x - 45 = 90

2x - 45 = 90

2x = 135

x = 67.5, so x - 45 = 22.5

Answer: 22/3

Step-by-step explanation:

So, the first step is to add 9/2 to both sides. We cant do that unless there is a common denominator between -8/3 and 9/2. I will leave the 1/4 alone because we will have to divide that later. When you divide a fraction, you multiply by the reciprocal, which doesnt require a change in denominator. That is my reason for not changing the 1/4.

The common denominator of the two would be 6.

\(-\frac{16}{6} =\frac{1}{4}x-\frac{27}{6}\)

Add the 27/6 to both sides

\(\frac{11}{6}=\frac{1}{4}x\)

Divide the 1/4 to both sides

\(x=\frac{11}{6}*\frac{4}{1} =\frac{44}{6}= \frac{22}{3}\)

The original dimensions of the piece of metal were 15 inches by 20 inches.

To solve this problem, we can use the given information to set up an equation. Let's assume that the width of the rectangular piece of metal is x inches. According to the problem, the length of the piece of metal is 5 inches longer than its width, so the length would be (x+5) inches.

When squares with sides 1 inch long are cut from the four corners, the width and length of the resulting box will be reduced by 2 inches each. Therefore, the width of the box will be (x-2) inches and the length will be ((x+5)-2) inches, which simplifies to (x+3) inches.

The height of the box will be 1 inch since the flaps are folded upward.
Now, let's calculate the volume of the box using the formula Volume = length * width * height.

Substituting the values, we have:

234 = (x+3)(x-2)(1)

Simplifying the equation, we get:

234 = x^2 + x - 6

Rearranging the equation, we have:

x^2 + x - 240 = 0

Now, we can solve this quadratic equation either by factoring or by using the quadratic formula. Let's use factoring to find the values of x.

Factoring the equation, we have:
(x+16)(x-15) = 0
Setting each factor equal to zero, we get:
x+16 = 0 or x-15 = 0
Solving for x, we have:
x = -16 or x = 15
Since the width cannot be negative, we take x = 15 as the valid solution.
Therefore, the original dimensions of the piece of metal were 15 inches in width and (15+5) = 20 inches in length.

Continuous random variable is a random variable that can take on a continuum of worth. In alternative words, a random variable is said to be continuous if it supposes a value that falls between a particular interval.

A continuous random variable can be described as a random variable that can take on an infinite number of possible values. Due to this, the probability that a continuous random variable will take on a fixed value is 0.

The probability density function of a continuous random variable can be explained as a function that gives the probability that the value of the random variable will drop between a range of values. Let X be the continuous random variable, then the formula for the pdf, f(x).

The length of AC is 12.5 and the length of AD is 3.

A triangle is a three-sided polygon because it has three edges and three vertices. The most important attribute of a triangle is the sum of its internal angles to 180 degrees

Given triangle ABC,

and D is a point on AB and E is a point on AC,

and forms a triangle ADE,

and  DE is parallel to AC,

taking ΔABC and ΔBDE

∠B = ∠B  (common angle)

because DE is parallel to AC, so corresponding angles are equal,

so ∠A = ∠D

and ∠C = ∠E

ΔABC ≈ ΔBDE (triangles are similar)

since both triangles are similar the ratio of their corresponding sides is equal,

AB/BD = AC/DE = BC/BE

given BD = 2, BE = 4, DE = 5 and EC = 6

BC = EC + BE = 4 + 6

BC = 10

AC/DE = BC/BE

AC = 5(10/4)

AC = 12.5

and AB/BD = BC/BE

AB = 2(10/4)

AB = 5

AD = AB - BD

AD = 5 - 2

AD = 3

Hence AC = 12.5 and AD = 3.

The triangle XYZ is formed by the next points:

X=(2, 5) Y=(0, 2) Z=(3,1)

The transformations that have occurred in the XYZ triangle are:

1. A reflection over the x-axis.

It will result in a change on the sign of the x-coordinate, then the new coordinates are (-x, y):

X'=(-2, 5) Y'=(0, 2) Z'=(-3,1)

2. A translation of 3 units to the right and 5 units down.

Then, the new coordinates are given by (x+3, y-5)

X'=(-2+3, 5-5) Y'=(0+3, 2-5) Z'=(-3+3,1-5)

X'=(1, 0) Y'=(3, -3) Z'=(0,-4)

Step-by-step explanation:

The value of the length of DP in the diagram where P is the circumcenter of the triangle is: 15 units.

The circumcenter is the point in the triangle where the perpendicular bisectors of the sides of the triangle intersect.

In the triangle given where P is the circumcenter, we have:

AD = DB

Substitute

2x + 14 = 8x - 52

2x - 8x = -14 - 52

-6x = -66

x = 11

AD = 2x + 14

Plug in the value of x

AD = 2(11) + 14

AD = 36

Also, AP = BP = CP = 39

AP = 39

Considering right triangle, ADP, to find DP, apply the Pythagorean theorem:

DP = √(AP² - AD²)

DP = √(39² - 36²)

DP = 15 units.

The property you are referring to is called the associative property of multiplication. According to this property, when multiplying three numbers, the grouping of the numbers does not affect the result. In other words, you can change the grouping of the factors without changing the product.

In the equation you provided: 3x(5x7) = (3x5)7

The associative property allows us to group the factors in different ways without changing the result. So, whether we multiply 5 and 7 first, or multiply 3 and 5 first, the final product will be the same.

Answer:

\(\int\limits^5_1 {(x^2-x+1)} \, dx= \frac{100}{3}\approx33.33units^2\)

Step-by-step explanation:

To determine the area of the definite integral, we take each term and find its corresponding integral. We know that \(\int\limits {x^n} \, dx =\frac{x^{n+1}}{n+1} +C\), so therefore we rewrite the expression as \(\frac{x^3}{3}-\frac{x^2}{2}+x\).

Now, we plug in each limit into the expression and find the difference between them:

\((\frac{5^3}{3}-\frac{5^2}{2}+5)-(\frac{1^3}{3}-\frac{1^2}{2}+1)\)

\((\frac{125}{3}-\frac{25}{2}+5)-(\frac{1}{3}-\frac{1}{2}+1)\)

\((\frac{250}{6}-\frac{75}{6}+\frac{30}{6} )-(\frac{2}{6}-\frac{3}{6}+\frac{6}{6})\)

\((\frac{205}{6})-(\frac{5}{6})\)

\(\frac{200}{6}\)

\(\frac{100}{3}\)

Therefore, \(\int\limits^5_1 {(x^2-x+1)} \, dx= \frac{100}{3}\approx33.33units^2\)

Step-by-step explanation:

So a parallelogram has 2 set of sides which are parallel and equal. So if you're given two adjacent sides, that means you're given a side from each set of sides, which are equal. This means the perimeter is simply: 2(x+3) + 2(x+2). This can be further simplified by distributing the 2 which gives you the equation: 2x+6+2x+4, which further simplifies to 4x+10.

Answer:

17.32 meters

Step-by-step explanation:

Let’s call the height of the tower H. The distance from the point to the base of the tower is 10 m. The angle of elevation from the point to the top of the tower is 60 degrees.

Using trigonometry, we can calculate that:

tan (60) = H / 10

H = 10 * tan (60)

H = 10 * √3

H = 17.32 m

Therefore, the height of the tower is 17.32 meters.

Answer:

x = 19

Step-by-step explanation:

Assuming the question was (5x + 4)° (8x – 71)°=180° not (5x + 4)° (8x – 710°,

Simplifying

(5x + 4) + (8x + -71) = 180

Reorder the terms:

(4 + 5x) + (8x + -71) = 180

Remove parenthesis around (4 + 5x)

4 + 5x + (8x + -71) = 180

Reorder the terms:

4 + 5x + (-71 + 8x) = 180

Remove parenthesis around (-71 + 8x)

4 + 5x + -71 + 8x = 180

Reorder the terms:

4 + -71 + 5x + 8x = 180

Combine like terms: 4 + -71 = -67

-67 + 5x + 8x = 180

Combine like terms: 5x + 8x = 13x

-67 + 13x = 180

Solving

-67 + 13x = 180

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '67' to each side of the equation.

-67 + 67 + 13x = 180 + 67

Combine like terms: -67 + 67 = 0

0 + 13x = 180 + 67

13x = 180 + 67

Combine like terms: 180 + 67 = 247

13x = 247

Divide each side by '13'.

x = 19
