Which step is the same when constructing an inscribed square and an inscribed equilateral triangle?

Answer:

I'm not sure about this one but you can try a=40

Step-by-step explanation:

Answer:

a = 30°

Step-by-step explanation:

Sum of the angles in a triangle is 180°

32° + 2a - 17 + 180° - ( a + 45° ) = 180°

32 + 2a - 17 = a + 45

a = 45 + 17 - 32

a = 30°

Step-by-step explanation:

g(x) = y = 8 - 2x

(A) First transform the function in terms of x :

x = y - 8 / 2

(B) Replace x with y :

[tex] {g}^{ - 1} (x) = y = \frac{x}{2} - 4[/tex]

Answer:

1/26 ; 1/26 ; 1/52

Step-by-step explanation:

Given the following :

A deck of 52 cards contains :

Red hearts, Red stars, black triangles, black circles

Each type of card is numbered from 1 - 13

Therefore,

Number of each type of card = 13, all numbered distinctly with digits between 1 - 13

Probability = (number of required outcomes / total number of possible outcomes)

If one card is drawn from the deck:

Probability of picking a red one :

This is either a red heart numbered 1 or a red red star numbered 1,

Therefore, Required outcomes = 2

Total possible outcomes = 52

P(a red one) = 2 / 52 = 1/26

B) A black three

This is either a black triangle numbered 1 or a black heart numbered 1,

Therefore, Required outcome = 2

Total possible outcomes = 52

P(a black three) = 2 / 52 = 1/26

C.) A six of hearts :

A hearts numbered six = 1

Therefore, Required outcome = 1

Total possible outcomes = 52

P(a black three) = 1 / 52 = 1/52

Answer:

y = 3/2x -5/2

Step-by-step explanation:

Slope intercept form is

y = mx+b  where m is the slope and b is the y intercept

3x- 2y = 5

Solve for y

Subtract 3x from each side

3x -3x- 2y =-3x+ 5

-2y = -3x+5

Divide by -2

-2y/-2 = -3x/-2 +5/-2

y = 3/2x -5/2

Answer:15

Step-by-step explanation: We know L+B+E=53 books

Loryn=L

Brian=L-7

L+2L+L-7=53

Then solve for L

Leaving you with L=15

Check

15+2(15)+(15-7)

Answer:

Christopher Columbus

Step-by-step explanation:

According to the hystoriartors:

Christopher Columbus

Answer:

[tex]Christopher[/tex] [tex]Columbus[/tex] [tex]and[/tex] [tex]Leif Eriksson[/tex]

Step-by-step explanation:

[tex]we[/tex] [tex]celebrate[/tex] [tex]columbus[/tex] [tex]day[/tex]

Columbus Day is for Christopher Columbus, who had discovered America.

Leif Eriksson was the first one who found America. While most people think it might have been Columbus. In conclusion, Leif Eriksson discovered America (well, Columbus gets some credit too for finding America.)

The answer to your question: Leif Eriksson, or Columbus.

Leif Eriksson found America Half a millennium before Columbus.

So let’s just take it as... that they both were one of the ones to find America :)

Hope this helps!

Answer:

b + 18 = 7

77 = 7b

9 = b - 2

Answer:

[tex] x = 2 [/tex]

Step-by-step explanation:

Figure B = 2½ the size of figure A

One side of figure B is given as 5, therefore, 5 = 2½ of x in figure A.

Thus, [tex] 5 = 2\frac{1}{2}*x [/tex]

Solve for x

[tex] 5 = \frac{5}{2}*x [/tex]

[tex] 5*2 = \frac{5x}{2}*2 [/tex]

[tex] 10 = 5x [/tex]

[tex] \frac{10}{5} = \frac{5x}{5} [/tex]

[tex] 2 = x [/tex]

[tex] x = 2 [/tex]

Answer:

7 hours

Step-by-step explanation:

810 - 180 = 630

630/ 90 = 7

Answer:

x = 7 h

Explanation:

First, we write the data of the problem.

Alex travels 810 miles away

Train - 90 miles / h

Alex covers 180 miles.

How many hours does Alex walk in the distance?

1. Calculate the distance Alex still has to travel.

 810 miles - 180 miles = 630 miles

2. We take into account the speed of the train to calculate how many hours Alex will cover the remaining distance.

90 miles .... 1 h

630 miles .... x h

x = 630 milesx1h / 90 miles

x = 7 h

Rationalization.  

                                                                              2 + i

For example:  " rationalize the denominator of ---------  "

                                                                               -3 + i

Answer:

A.   x = 5

Step-by-step explanation:

2 + 8x = 11x - 13   -------- subtract 2 from both sides

2 + 8x - 2 = 11x - 13 - 2

8x = 11x - 15         -------- subtract 11x from both sides

8x - 11x = 11x - 15 - 11x

-3x = -15

x = -15 / -3

x = 5

Answer:

x=5

Rational numbers: fractions with an integer numerator and a nonzero integer denominator.

Irrational numbers: numbers that are not rational such as π, root 3, and any non repeating, non ending decimal.

Answer:

Hello!

Step-by-step explanation:

you know 3x = 4x-24

simplify

x=24

so thats x

now idk what you want me to find but

3x = 72

Ok, now I understand the question, mRST = 72

Answer:

28 cm

Step-by-step explanation:

vertical side of each parallelogram is (y-6)/2 cm

perpendicular height of each parallelogram is 7 cm

Total area = 4sh

308 = 14(y-6)

y-6 = 22

y = 28 cm

Answer:

The SQ Root of 493

Step-by-step explanation:

Becaues this triangle is a right triangle, we can find the missing side usiing the pythagorean theorum.

The pythagorean theorun states A^2 + B^2 = C^2, so 18^2 + 13^2= 439

Then all you have to do is find the sq root of 439, but this question askes you not to.

Hope this helps :)

Answer: (1,-1/2)

Step-by-step explanation:

Point C on the coordinate plane has the coordinates (4,-2) after a dilation with a scale factor of 1/4 we will have to multiply the coordinates each by 1/4 to find the new coordinates.

So x =  4 * 1/4 = 1   Now the new x coordinate is 1  

-2 * 1/4 =  -2/4 = -1/2      Now the new coordinate for y is also -1/2

So we will now have the coordinates (1,-1/2)

Answer:

The temperature of the solution after 3 hours rounded to the nearest whole degree is -6 C

Step-by-step explanation:

From the question, the temperature of the chemical solution at the start of the experiment is -14.96 C.

Now, if the temperature increases by 2.9 C each hour,

Then, after 3 hours, the temperature of the chemical solution would have increased by

2.9 C/h × 3 h

8.7 C

Hence, the temperature of the chemical solution would have increased by 8.7 C after 3 hours.

The temperature of the chemical solution after 3 hours will be

-14.96 C + 8.7 C

= -6.26 C

≅ -6 C (to the nearest whole degree)

TA DA

To convert mm to m, divide by 1000:

794/1000 = 0.794 m

1 day = 24 hours

1 hour = 3600 seconds

24 x 3600 = 86,400 seconds in a day

Answer:

Step-by-step explanation:

To convert 794mm into m

1000mm = 1m

794mm = xm

m = 794/1000

m = 0.794m

One day to secs is

= 84,400secs

3hour =300words

1 hour = 300/3

=100

5hours=100*5

=500 words
