Find angle R as shown by the picture

I need an explanation
Will name brainliest

Answer:

x = 31

Step-by-step explanation:

These angles are complementary so:

2x + x - 3 = 90

3x - 3 = 90

3x = 93

x = 31

9514 1404 393

Answer:

  >180° (more than 180°)

Step-by-step explanation:

Angles are classified as ...

It seems that we're looking at definitions:

  obtuse : >90° :: reflex : >180°

Answer:

3x+2=17 is the equation and x=5

Step-by-step explanation:

Answer:

Equation: 2 + 3x = 17

x = 5

Step-by-step explanation:

2 more than means: 2 +

3 times a number means: 3x

Is 17 means: = 17

Combine them all together:

2 + 3x = 17

Find x:

2 + 3x = 17

3x = 17 - 2

3x = 15

x = 5

Answer:

Step-by-step explanation:

Answer:

26 degrees :)

Step-by-step explanation:

Answer/Step-by-step explanation:

3. Volume = l*w*h = 1*3*1 = 3 ft³

Surface area = 2(lw + wh + lh) = 2(1*3 + 3*1 + 1*1) = 14 ft²

4. V = 216 cm³

w = 6 cm

l = 12 cm

h = ?

V = l*w*h

Plug in the given values and find h

216 = 12*6*h

216 = 72*h

216/72 = h

h = 3

Surface area = 2(lw + wh + lh)

= 2(12*6 + 6*3 + 12*3) = 252 cm²

5. V = 120 m³

h = 4 m

l = 5 m

w = ?

V = lwh

Plug in the given values

120 = 5*w*4

120 = 20*w

120/20 = w

w = 6 m

Surface area = 2(lw + wh + lh)

= 2(5*6 + 6*4 + 5*4)

= 148 m²

6. V = 726 in³

h = 11 in

w = 33 in.

l = ?

V = lwh

Plug in the values

726 = l*33*11

726 = l*363

726/363 = l

l = 2 in

Surface area = 2(lw + wh + lh)

= 2(2*33 + 33*11 + 2*11)

= 902 in²

[1] … … 2x₁ + 0x₂ + 3x₃ = 3

[2] … … 4x₁ - 3x₂ + 7x₃ = 5

[3] … … 8x₁ - 9x₂ + 15x₃ = 10

Since [1] is already free of x₂, you might as well start by eliminating x₂ from the other two equations. Add -3 times [2] to [3] :

-3 (4x₁ - 3x₂ + 7x₃) + (8x₁ - 9x₂ + 15x₃) = -3 (5) + 10

-12x₁ + 9x₂ - 21x₃ + 8x₁ - 9x₂ + 15x₃ = -15 + 10

-4x₁ - 6x₃ = -5

[4] … … 4x₁ + 6x₃ = 5

Now eliminate x₃ in [1] and [4]. Add -2 times [1] to [4] :

-2 (2x₁ + 3x₃) + (4x₁ + 6x₃) = -2 (3) + 5

-4x₁ - 6x₃ + 4x₁ + 6x₃ = -6 + 5

0 = -1

which is a contradiction. This means the system has no solution.

Answer:

37.7

Step-by-step explanation:

First you would need to find the radius by dividing 24 by 2 which is 12. Then multiply the radius by pie (3.14) and the answer should be 37.68 rounded to the nearest tenth, 37.7.

Answer:

Easy! The answer is 100!

Count how many cubes are in each row, which is 10. Count how many stacks are there, which is also 10. 10 times 10 = 100!

Answer:

20

Step-by-step explanation:

Answer: 20

Step-by-step explanation: 115-95=20

In a 30-60-90 triangle the hypotenuse is 2 times the shortest leg.

In the problem, they multiplied the shortest leg by sqrt(3)

Hypotenuse = shortest leg x 2

Hypotenuse = 7 x 2 = 14 units

how do i draw the graph

Step-by-step explanation:

Answer:

I attached my sketch of it. Notice how as the y value goes down 1, the x value goes to the right 2.

I would appreciate Brainliest but no worries.

Answer:

First Blank (4) Second Blank (3)

Step-by-step explanation:

The square in the middle is the base and if you count the side units you will have 4 on each side. From the square the triangle points up 3 units on the graph.

Answer:

5:3

Step-by-step explanation:

step one: reduce the fraction

(since 5/3 is a reduced as it can get we can 'skip' this step)

step two: rewrite as a ratio

5/3  

=5 : 3

good luck :)

i hope this helps

brainliest would be highly appreciated

have a nice day!

Answer:

25.65

Step-by-step explanation:

Answer: rational number

Step-by-step explanation:

Mixed numbers are all rational numbers because they can be expressed as a fraction. To be a rational number, a number must be able to be written

Answer:

6

Step-by-step explanation:

The question indicates that the triangles are similar. The sides of FGH are 12, 15, and 20. The measured side of MNP is 10, which is 1/2 of 20. So since NM is the shortest side, it corresponds to the shortest side of FGH, which is 12. 1/2 of 12 is 6.

Please let me know if you have questions.

Answer:

5.75

Step-by-step explanation:

Think about it like this, which number is changing with "X" ? Obviously the total f(x) and the number being multiplied by x (the slope) 4.99 so the fixed number is 5.75

Answer: 270

Step-by-step explanation:

90x3=270

Answer:

I mean

Step-by-step explanation:

Just multiply 90 by 3 since it says that it's THREE times as long. Btw you would get 270! So this should help! Well I guess you have to add another 90 to get the area of the closet. Don't quote me on that.

Answer:

50-50 on both because there 3 even and 3 odd numbers

Answer:

50% chance of either or 1/2

Step-by-step explanation:

50% of either

Look a die has 12 sides

6 numbers are odd and the other 6 even

If you randomly roll a die you will have 6/12 chances of landing on a even number and a 6/12 chance of landing on a odd number

now 6/12 can be simplified to 1/2 which is 50%

Hope that helps!
