What is the value of x?

Mathematics
1 answer:
Firlakuza [10]2 years ago
8 0

(10 + 3x)° + (x - 30)° = 180°

(3x + x)° + (10 - 30)° = 180°

4x° - 20° = 180°

4x° = 180° + 20°

4x° = 200°

x° = 200/4

x° = <u>50°</u>

So, the value of x is 50°

Find the volume of this composite figure and explain how you got your answer
Damm [24]
To solve this, we work out the volume of the two shapes (the cuboid and the pyramid) and then add them together.

We get the volume of the cuboid by multiplying the base by the width by the length:

Volume of cuboid = 6 x 6 x 4 

                               = 144m³

Now to get the volume of the pyramid, we multiply the base by the length by the height, and then we divide by three.

Volume of pyramid = 6 x 6 x 8 
÷ 3
                                    = 96m³
-------------------------------------------------------------------------------------------------------------
Answer:
Now that we know the two volumes, we simply add them together:

144 + 96 = 240m³

So the volume of the composite sold is 240m³

What is the range of the function f(x)=(x+4)²+5
hammer [34]

Answer:

Range=\left \{y|y\geq 5\right \}

Step-by-step explanation:

Since given the expression, this represents graphically a parabola with arms pointing up, and a vertical translation of its vertex 5 units up, then the range of the function must be all the y values such that they are greater or equal to 5. This is written as:

Range=\left \{y|y\geq 5\right \}

The perimeter of a rectangle is 28 cm and<br>its length is 8 cm. Find its breadth.​
Yakvenalex [24]
Answer:
The width of the rectangle is 6cm.

Explanation:
Perimeter=2(length+width)
28=2(8+w)
Distribute 2 into the parentheses
28=16+2w
Combine like terms
28-16=2w
12=2w
Divide both sides by 2
6=w

I hope this helps! Please comment if you have any questions.

Which function is quadratic?
PilotLPTM [1.2K]

Answer:

step 1. A, B,D are incorrectly written as these are not all coordinates. they must be written (x, y)

step 2. so the question becomes is C a quadratic

step 3. The x values must be evenly spaced. the x values are evenly spaced by a difference of 4

step 4. write out the y values: -126, -14, 2, 18

step 5. write out the differences: 140, 16, 16

step 6. write out the differences: -124, 0.

step 7. after doing this twice the numbers nust be the same for this to be a quadratic which they aren't

step 8. C is not a quadratic.
