Delta Math: Angle Terminology With Equations

Answers

Answer 1

Answer:

m∠A = 139°

Step-by-step explanation:

First we must know that

Supplementary angles equal to 180 degree.

Since we know that supplementary angles equal to 180 degree we can solve now:

Putting m ∠A and m ∠ B together and put the = 180

( 7x - 15 ) + ( 2x - 3 ) = 180

Now solving for x:

( 7x - 15 ) + ( 2x - 3 ) = 180

9x - 18 = 180

9x - 18 + 18 = 180 + 18

9x  = 198

9x/9 = 198/9

x = 22

Hence,  Angle A will have a measure of 7x - 15 which means  7 ×  22 -15 = 154 - 15 = 139°

m∠A = 139°

The measure of Angle B will be 2x - 3 = 2 • 22 - 3 = 44 - 3 = 41°

m∠ B = 41°

139 + 31= 180

[RevyBreeze]

Answer 2

Supplementary angles have sum 180°

7x-15+2x-3=1809x-18=1809x=198x=198/9x=22

m<A

7(22)-15=154-15139

A rectangular prism has a height of 4.5 cm, length of 7.2 cm and a width of 9 cm. Joe is going to cover the sides only. How much paper will he need?

Answers

Answer:

210.6cm^2

Step-by-step explanation:

1) In the diagram below the shape of the rectangular prism is shown:

where L=7.2, W= 9 and H=4.5

In order to cover only the sides, the area of the front and back faces and the side faces should be added, the top and bottom faces should not be

so the area of front and back faces= 2 (length *width) (multiply by 2 to account for both the front and back face, instead of just one face)

=2(7.2)(9)= 129.6 cm^2

area of side faces: 2(W)(H)=2*9*4.5=81cm^2

129.6cm^2+81cm^2=210.6 cm^2

How many solutions exist for the given equation? 3(x 10) 6 = 3(x 12) zero one two infinitely many

Answers

The given equation 3(x+10)+6=3(x+12) has infinitely many solutions.

We have the following expression

[tex]3(x+10)+6=3(x+12)[/tex]

We must rewrite both sides of the equation.

For this, we use the distributive property.

What is the distributive property?

A (B + C) = AB + AC

We have then

3(x+10)+6=3(x+12)

Adding like terms we have

3x+30+6=3x+36

3x+36=3x+36

We observe that we have two equal equations.

Therefore, the equations intersect for any value of x.

Therefore, the equation has infinite solutions.

What is the volume of this solid?
O A. 63
O B. 10
O c. 27
O D. 39

Answers

Answer:

Find the cube's volume first (because it's the simplest figure) by using the formula;

(Formula for vol. of cube)

V = [tex]s^{3}[/tex]

Where 's' stands for one side of the cube raised to the power of three.

or

V = w · l · h

Where 'w' stands for the width, 'l' stands for the length, and 'h' stands for the height.

Plug in the values you know since they literally give it to you (I'll be using the formula [tex]s^{3}[/tex]);

V = [tex]s^{3}[/tex]

V = 3^3 → (The symbol ' ^ ' means to the power of.)

V = 27, is the volume of the cube.

Now we find the volume of the pyramid using the formula;

(Formula for vol. of pyramid)

V = (l · w · h) · 1/3

Where 'l' means the length, 'w' the width, and 'h' the height whereas the 1/3 is just dividing the product of those three by 3.

Plug in the values you know using both the lengths from the cube and pyramid.

What we know of the dimensions for the cube:

Length = 3

Width = 3

Height = 3(we won't use)

What we know of the dimensions for the pyramid:

Height = 4

Use these to figure out the volume for the pyramid.

V = (l · w · h) · 1/3

V = (3 · 3 · 4) · 1/3

V = 36 · 1/3

V = 36/3

V = 12, is the volume of the pyramid.

Add your volumes:-

27(cube vol.) + 12(pyramid vol.)

= 39 is the volume for this whole solid, your answer is D.

its 1/7 because if you have a pizza and you cut it in 3 pieces, it will be bigger than a pizza cut in 4 pieces.

So basically if you buy a pizza and you were originally going to cut it in 3 pieces, but then one of your other friend wants a piece, so now you will have to cut it into 4 pieces which will give you a smaller piece and the same way cutting a pizza into 7 pieces will make it way smaller

Write down equations what you know.

NML is 28x-1, this is the total angle.
NME is 5x-1, this is the small part of the angle
EML is 115, this is the large part of the angle

So,
NME + EML should equal NML
5x-1 + 115 = 28x-1
Solve for x
Add 1 both sides
5x+115 = 28x
Subtract 5x both sides
115 = 23x
Divide 23 both sides

Which equation describes this line?

Answers

Answer:

y=2x+4

Step-by-step explanation:

**Your line isn't clearly shown on point with the grid**

If you want this in the slope-intercept form then here it is:

Slope-intercept formula: y=mx+b

Your coordinates: (-3,2) and (1,10)

To find the slope (which is the "m" in the formula) you need to do this formula:

y2 - y1 / x2 - x1 =

(The 2's and 1's should be subscript)

10-2/1-(-3) = 8/4

8/4=2

The slope should be 2

Formula right now: y=2x+b

You need to find the y-intercept:

That should be a point on the y-axis.

(0,n) **N is used for a variable since we don't have a number yet.

In your coordinate plane, (0,4) is your y-intercept.

When writing the y-intercept in the formula don't write a coordinate write the "y"

Formula: y=2x+4
