What number makes the equation true enter the answer in the text box

Step-by-step explanation:

∠2 and ∠7 are alternate exterior angles so they are equal.

So you can create the equation

40x-48 = 20x+52   Subtract 20x from both sides. Add 48 to both sides.

20x = 100

x = 5

if you need  m∠2 Substtute 5 for x in 20x+52  

20(5) + 52 = 100 +52   m∠2= 152°

m∠7  40(5) - 48 =  200-48  m∠7= 152°

The value of the variable x is given as 8000.

Some of the rules of exponents are as follows,

The product of two exponents having the same power is equal to the power of their base multiplied.

The product of two exponents having the same base is equal to the sum of the powers of different exponents to the same base.

The given exponential expressions are as below,

n⁴ = 20x

And, n³ = x

Then as per the rule of exponent, the following it can be written as,

n³ = x

⇒ n × n³ = n × x

⇒ n⁴ = nx

⇒ 20x = nx

⇒ n = 20

Then, x = 20³ = 8000

Hence, the value of x is found to be 8000.

Answer:

a; 175 centimeters

Step-by-step explanation:

One meter is 100 centimeters

this means that 3.25 meters is essentially just 325 centimeters

if she wants to make 100 name tags she must do 100 times 5 to get how many centimeters of ribbons she needs

100 * 5 = 500

she only has 325 centimeters so you subtract 325 from 500

500 - 325 = 175

Answer:

$45

Step-by-step explanation:

Given the following :

Amount deposited in first year = $150

Interest rate (r) = 2% = 0.02

First year:

Simple Interest = principal * rate * time

= $150 * 0.02 = $3

2nd year:

Principal = $150 * 2 = $300

($300 * 0.02) = $6

3rd year:

Principal = $150 * 3 = $450

($450 * 0.02) = $9

4th year:

Principal = $150 * 4 = $600

(600 * 0.02) = $12

5th year:

Principal = $150 * 5 = $750

($750 * 0.02) = $15

Total interest earned :

$(3 + 6 + 9 + 12 + 15)

= $45

Answer:

Step-by-step explanation:

Similarity statements are written with corresponding vertices in the same order. So, there are two tasks involved: (1) identifying corresponding vertices; (2) making sure they are written in the same order in the similarity statement.

Here, we could go to the trouble to identify all pairs of corresponding vertices. Then we could write our own similarity statements and see which answer choice corresponds. However, it is sufficient to do just enough work to allow elimination of bad answer choices.

Sometimes in figures like this, it is difficult to tell the short side of the right triangle from the long side. (This figure is pretty helpful.) However, it is always possible to identify the hypotenuse of each triangle. They are ...

  RT, RS, ST

What this means is that these letters should appear in the same spots in each part of the similarity statement.

  (a) RT are in the 1st and 3rd spots of the first triangle name. In the second triangle name, those spots are occupied by SU--not a hypotenuse. (rejected)

  (b) The 1st and 3rd spots of each statement are occupied by RT, RS, ST, so this is a viable candidate.

  (c) The 1st and 3rd spots of the first triangle name are occupied by ST, but those spots of the second triangle name are SU--not a hypotenuse. (rejected)

  (d) The 1st and 2nd spots of the first triangle name are occupied by RT, and those spots in the second triangle name are RS. However, those spots in the third triangle name are TU--not a hypotenuse (rejected).

The only viable choice for similarity statement is the second choice:

  ΔRST ~ ΔRUS ~ ΔSUT

__

We can find segment 'a' by writing a proportion between sides of the largest and medium-size triangles:

  hypotenuse/long side = (21 +a)/29 = 29/21

  21(21 +a) = 29² . . . . . multiply by 29·21

  441 +21a = 841 . . . . simplify

  21a = 400 . . . . . . . subtract 441

  a = 400/21 . . . . . . . . . . . divide by 21. (eliminates choices C and D)

At this point, we can solve for b in similar fashion. However, it is sufficient to use "triangle sense" to eliminate the remaining bad choice. We know the hypotenuse of any right triangle is the longest side. Here, that means ...

  b > 20 . . . . . (eliminates choice B)

The only viable answer choice is A:

  a = 400/21, b = 580/21

__

Additional comments

For multiple-choice questions, you can arrive at a solution just as effectively by eliminating bad choices as you can by working the problem in detail to develop the correct choice. Here, we try to use "common sense" to simplify the work as much as possible. This saves time, which is what you want when you're working a timed assignment.

__

This geometry has several interesting features. If you start at the right angle and write side lengths in order clockwise, the two "inside triangles" have the order {longest side, hypotenuse, shortest side}. The overall outside triangle has the order {shortest side, hypotenuse, longest side}. That is, the order of the outside triangle vertices is counterclockwise for the same order of corresponding sides. Realizing/remembering this can immensely simplify the process of writing similarity statements for these triangles.

Another feature is one we demonstrated in the solution for 'a' in the second problem: the length of a segment touching the longest hypotenuse is the geometric mean of the lengths of the hypotenuse segments it touches. In the case in point: 29 = √((21)(21 +a)). We could also write the relationship: 20 = √((21)(a)), perhaps getting there more directly:  a=400/21. And finally, b = √((a(a+21)). These geometric mean relationships all derive from the proportions you can write using triangle similarity.

(The geometric mean of two numbers is the square root of their product. For n numbers, it is the n-th root of their product.)

You should be able to note that this is a parabola which opens downward. Taking the derivative and setting it to -0- will yield the max of the equation, That is

[tex]y=-\frac{1}{3} x^{2} +2x-4[/tex] ⇒ [tex]\frac{dy}{dx} =-\frac{2}{3} x+2=0[/tex] ⇒ [tex]x=3[/tex]

Answer:

Step-by-step explanation: 2x+6

Another factor will be x and ( x + 1 )² and the solution will be -1, 0, and 1/2.

In mathematics, every real-world issue may be transformed into an equation, sometimes in the form of a factor, which must then be expanded to get a solution.

Expanded form is the term used in mathematics to refer to the process of expanding a number to convey the value of every digit and place value.

Given,

p(x)=2x⁴ + 3x³ −x one factor is (2x−1)

To find another factor we divide p(x)=2x⁴ + 3x³ −x by (2x−1)

Then we got remainder as 0 and quotient ( x³ + 2x + 1 )

So,

(2x−1) ( x³ + 2x² + x ) = 0

(2x−1) (x) ( x² + 2x + 1) = 0

(2x−1) (x) (x + 1)² = 0

Now the solution to this

(2x−1) = 0 ⇒ x = 1/2

(2x−1) (x) ( x² + 2x + 1) = 0 ⇒ x = 0

And

(x + 1)² = 0 ⇒ x = -1

Hence, another factor will be x and ( x + 1 )² and the solution will be -1, 0, and 1/2.

The least value plotted on the line plot is 18.0, the greatest value plotted on the line plot is 22.0, and the height of inches that occurs the most often is 19.5 with 3 times.

In a set of data values, the mode is the value that appears the most frequently.

A.) The least value plotted on the plot is the minimum height of the plant Harold, therefore, the least value plotted on the line plot is 18.0.

B.) The greatest value plotted on the line plot is 22.0 is the maximum height of plant Harold, therefore, the greatest value plotted on the line plot is 22.0.

C.) The height of inches that occurs the most often is the mode of all the data points of the height of the plant that is given to us, therefore, the height of inches that occurs the most often is 19.5 with 3 times.

Answer:

1800 in^3

Step-by-step explanation:

Step-by-step explanation:

what was the difficulty here ?

supplementary angles fill up to 180°.

complementary angles fill up to 90.

50° complement is 90-50 = 40°.

supplement is 180-50 = 130°.

bisected angle is 50/2 = 25°.

90-34=56° complement is 34°.

supplement is 180-56 = 124°.

bisected angle is 56/2 = 28°.

35×2=70° complement is 90-70 = 20°.

supplement is 180-70 = 110°.

bisected angle is 35°.

180-135=45° complement is 90-45 = 45°.

supplement is 135°.

bisected angle is 45/2 = 22.5° = 22°30'
