Answer:

90°

Step-by-step explanation:

1) There are 1080° in an octagon and there are eight sides, meaning that we have to divide. The equation would be: 1080÷8= 135. So each angle on the edge of the octagon is equal to 135°. An example for better understanding would be that angles like RST, TUV, VWP and PQR are each 135° Now we know that the measurements of the angles PQR and RST (They are the main angles we look at in this question)

2) We now have to find the angle SRT. Meaning that we now have to look at the triangle RST. We already know that the angle S is equal to 135° and the angles R and T are equal to each other. (You can even see with the RT line/angle connecting R and T) So now we have to complete the equation: 180-135= 45. (We have to subtract 135 from 180 because the angles we are supposed to be calculating are not reflex angles nor they exceed 180°) This means the angles R and T (because they equal the same) equal 22.5°

3) Now we have to just subtract everything. The equation would be:   135-22.5-22.5= 90° The answer would be 90° because we have to subtract the angle R and T (which are both 22.5°) from angle S (which is 135°) which would equal our answer 90°.

Answer:

(10t + u)(10u + t) = 4,930

100tu + 10t^2 + 10u^2 + tu = 4,930

101tu + 10t^2 + 10u^2 = 4,930

10t^2 + (101u)t + (10u^2 - 4,930) = 0

(101u)^2 - 4(10)(10u^2 - 4,930)

= 10,201u^2 - 400u^2 + 197,200

= 9,801u^2 + 197,200

We see that u = 5 gives 442,225.

√442,225 = 665

(10t + 5)(50 + t) = 4,930

500t + 10t^2 + 250 + 5t = 4,930

10t^2 + 505t - 4,680 = 0

2t^2 + 101t - 936 = 0

t = (-101 + √(101^2 - 4(2)(-936)))/(2×2)

= (-101 + √17,689)/4

= (-101 + 133)/4 = 32/4 = 8

So the numbers are 58 and 85.

58 + 85 = 143

Answer:

$3.04

Step-by-step explanation:

one orange costs about 25 cents (because 15 x .25333 equals 3.80, and round up to .25) so .25 x 12 is about $3.04

Answer:

I’m pretty sure that it is D because it says boundary and not just where it is at.

Step-by-step explanation:

If you have an equation for your graph you would substitute the y AND x with 0, you the solve the solution and if the solution is true then the space where (0,0) is located becomes the shaded area because that resembles the area in which everything is a positive solution with the equation. If it is false then the opposite area is then shaded because (0,0) doesn’t work with the problem.

I hope you get it right! Have a good week :D

Answer:

130

Step-by-step explanation:

complementary means it adds up to 90 degrees.

subtract that angle from 90 to get the complementary angle

supplementary angles add up to 180 degrees

subtract that angle from 180 to get the supplementary angle

Answer:

1) 45

2) 60

3) 36

4) 52

5) 20

6) 130

Step-by-step explanation:

In the first 3 questions, it's asking us for a complementary angle to the given angle.  A complementary angle is when 2 angles add up to 90 degrees.  So, we are given 45 degrees already, so we can subtract that from 90 to find it's complementary angle, which is also 45.  Continue to subtract from 90 for the next 2 problems.

In questions 4-6, we are asked to find an angle that is supplementary.  A supplementary angle is when 2 angles add up to 180 degrees.  We are given an angle that measures 128 degrees, so subtract 180-128 to get 52 degrees.  Continue subtracting from 180 for the next 2 problems.

Hope this helps! :)

Hello !

- for a triangle to be constructible, the longest side must be less than the sum of the other two sides. -

so :

67 smaller than 27+47 ?

67 ⟨ 74 it's the right answer.

I hope I helped you !!

Have a good evening !!!

Patrick can form a triangle using the rod lengths of 20 inches and 27 inches and 47 inches. The other combinations of rod lengths do not meet the conditions laid out by the triangle inequality theorem.

The subject of this question is Mathematics, specifically focusing on geometric properties of triangles. According to the triangle inequality theorem, a triangle can only form if the sum of the lengths of the two shorter sides is greater than the length of the longest side. In this context, Patrick uses scrap metal to build sculptures and wants to create triangles from metal rods which are 20 inches, 27 inches, 47 inches, and 67 inches long.                                                    Using the triangle inequality theorem, we can determine which combinations of rod lengths can form a triangle:

Answer:its  5600000

Step-by-step explanation:

Answer:

To solve the equation -(x + 3) = 2(x - 3) for x, we can follow these steps:

Step 1: Distribute the negative sign on the left side of the equation:

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

=> -x - 3 = 2(x - 3) (using the distributive property)

Step 2: Expand the right side of the equation:

-x - 3 = 2x - 6

Step 3: Add x to both sides of the equation to isolate the x term on one side:

-x + x - 3 = 2x + x - 6

=> -3 = 3x - 6

Step 4: Add 6 to both sides of the equation:

-3 + 6 = 3x - 6 + 6

=> 3 = 3x

Step 5: Divide both sides of the equation by 3 to solve for x:

3/3 = 3x/3

=> 1 = x

So, the correct value of x that makes the equation true is B. 1.

PLEASE MARK BRAILYISTT :D

Answer:

B, one

Step-by-step explanation:

In order to solve this, you can solve the equation. First, you can use the distributive property to get -x-3=2x-6. If you make the variables on one side and the constants on the other, you will get -3x-3=-6. This can further simplify to -3x=-6. Divide both sides by -3 to get that x=1. Then, the correct answer is B.

Answer: 10

Step-by-step explanation: The answer is 10 because xy means x times y, and since x = 10 and y = -2, 10 times -2 equals -20. Now you have to divide that by --2 which is just 2. So -20/2 equals -10. -10's absolute value is 10. Thus the answer is 10.

The data from the stem-and-leaf plot is:

10,

24,25,26,

30,30,32,33,

40,45,46

Add up those values

10+24+25+26+30+30+32+33+40+45+46 = 341

Then divide over n = 11 which is the sample size.

341/11 = 31 is the arithmetic mean.

=37/6

Simplify 37/6, the answer is

=6 1/6

Answer: 6 1/6

Step-by-step explanation:

Step 1: Add the whole numbers

3 2/3 + 2 1/2= 5 + 2/3 + 1/2

Step 2: Ignoring the whole number, add the fractions.

2/3+ 1/2

Find the LCM of 2 and 3, which is 6. Now make the denominators for both fractions 6, and multiply the numerators by whatever  you multiply the denominator to get to 6.

You know that to get 3 to 6, you multiply by 2. So then you also have to multiply the neumerator for that fraction by  2 as well. 2x2= 4, so the new neumeraator is 4

Now for the next fraction. To get from 2 to six, you multiply by 3. So multiply the neumerator by 3. 1x3= 3  , so the new neumerator is 3.

4/6+ 3/6= 7/6

Step  3: Add & Simplify

5+7/6= 5+1 1/6= 6 1/6.

Answer:

Step-by-step explanation:

This expression involves the distributive property. In the distributive property, there is a number followed by an equation in parenthesis.

3(n+6)

To simplify it, you have to multiply the first number by each number in the parenthesis, separately:

3(n+6)

3n + 3(6) or 3xn + 3x6 (same thing)

3n+18

Finally, we can check the other 4 choices to double check.

A. 3n+6 (wrong)

B. 2(n+6) + (n+6)=

2xn + 2x6 + n + 6

2n + 12 + n + 6

combine like terms, or all the terms that are the same. start with the Ns, then the numbers:

2n+n + 12+6

3n+18

C. 2(n+6)+n= 2n+2(6) +n = 2n+12+n= 2n+n+12= 3n+12

D.3n+18

E. 2n+2+n+4= 2n+n+2+4= 3n+6

Answer= B and D

Step-by-step explanation:

12• the graph pass by in × intercept - 3 / 2 or - 1 • 5

in y intercept 1 because

y - 1 = 2 / 3× means y = 2/3 × + 1 and y intercept we can get by assuming if × is = 0 and × value by assuming if y is equal to 0

so; × = { -3/ 2 , 0 } or { - 1 • 5 , 0 }

y= { 0 ,1 }

13 • by the same formula become the graph pass in × intercept -4/ 3 or 1• 3`

y intercept 4
