Answer:

What type of math this is text me back!

Step-by-step explanation:

Answer:

A) Three and three ninths plus seven and six elevenths equals 10 and eighty seven ninety ninths

Step-by-step explanation:

Translate these into numerical values: 3 3/9 + 7 6/11 = 10 87/99

Find a common denominator or multiple that your denominator's (9 and 11) share. Their lowest common multiple is 99.

Take 3 3/9's and multiple the denominator by 11 to get your denominator of 99. What you do to your denominator also must be reflected in your numerator, so multiply it by the same factor of 11. You will get 3 33/99

Repeat for 7 6/11. Multiply your denominator (11) by 9 to get your denominator of 99. Do the same in the numerator (6) to get 54.

Now add your new values. 3 33/9 + 7 54/99
Your fractional values will add up to 87/99, and your whole number values will add up to 10. In this case, your fractional values do not exceed 1, so there is no need to work any further. Your final answer is 10 87/99

Answer:

180

Step-by-step explanation:

Here,

b=15

c=9

Now,

[tex]=b^{2}-5c\\\\=15^{2} -5*9\\\\=225-45\\\\=180[/tex]

Answer:

180

Step-by-step explanation:

b^2-5c

Substitute 15 in for b

15^2=225 -> 225-5c

Substitute 9 in for c

5(9)=45

225-45 = 180

Answer:

0.66653334

Step-by-step explanation:

The area of the face of the square is the side length x the side length. So 0.3333 x 0.3333 = 0.11108889. Since a square has 6 sides, multiply 0.11108889 with 6. So it equals 0.66653334.

Answer:

D. 204 [tex]ft^{2}[/tex]

Step-by-step explanation:

the center square 11b x 12h = 132

17 - 11 = 6/2 = 3 this is the base for each of those right angles

3 x 12 = 36 x 2 = 72

132 + 72 = 204 [tex]ft^{2}[/tex]

Answer:

its d i think sorry if im wrong

Step-by-step explanation:

Answer:

There are six faces on the solid.

There are twelve edges on the solid.

There are eight vertices on the solid.

Step-by-step explanation:

The 3-D solid shape is a cube.

A cube is a regular hexahedron.

Hexahedron is a polyhedron with six faces (regular meaning all six are square).

So, there are six faces on a cube.

A cube has 12 edges because all faces are squares and congruent to each other, all 12 edges are the same length.

A vertex is a corner where edges meet. The plural is vertices.

a cube has eight vertices, a cone has one vertex and a sphere has none.

Answer:

The simplified answer is 7w - 12.

Step-by-step explanation:

-1(w+4) + 2(4w-4)

(-w -4) + (8w - 8)

7w - 12

Answer:

7w - 12

Step-by-step explanation:

-(w+4)+2(4w-4)

Step 1: Distribute

In this equation, there are two things being distributed, the -(w+4) and the 2(4w-4). Looking at -(w+4) makes you think that there is nothing to distribute but actually there is. Treat the - like a -1 so that it looks like -1(w+4) and then we distribute normally.

-1 x w = -w

-1 x 4 = -4

Put it together and you have:

-w-4

Then the 2(4w-4), with this, we need to distribute the 2 into the 4w and -4. To do this, you just multiply the numbers.

2 x 4w = 8w

2 x -4 = -8

Put those together and you have:

8w-8

After distributing, the equation should like:

-w-4+8w-8

Step 2: Combine Like-Terms

In the remaining equation, there are 4 things we can combine. The -w and 8w, and the -4 and -8. The reason that we are doing it in this order is because you cannot combine a number with a variable, like combining -4 with 8w. Now we just add (or subtract).

8w - w = 7w

-4 - 8 = -12

Leaving us with the fully simplified equation:

7w - 12

Answer:

1.75 is the answer

Step-by-step explanation:

1.75 x 12= 21

Answer:

102$

Step-by-step explanation:

(20/100*38)*5+(16/100*45)*6+(10/100*52)*4

=102$

im not good in maths so this what i think

Let's say we start with the true statement that 2 < 5

Multiplying each of those numbers by -1 means we have...

If the inequality sign stayed the same, then we'd have the false statement -2 < -5. Use a number line to see why this is false. Note how -2 is to the right of -5, so it should be larger.

To fix this error, we flip the inequality sign.

So we go from 2 < 5 to -2 > -5

Rule: Multiplying both sides by a negative number always flips the inequality sign.

Answer:

CE= 9cm, DE= 5cm, CD= 10.2956cm

Step-by-step explanation:

Let E be the point of the other triangle.

Using Pythagoras' Theorem,

CD= square root symbol (CE^2 + DE^2)

= square root symbol (9^2+5^2)

= 10.2956cm (6 sf)

Answer:1 inch is actually 80 inch so:

1 7/8 x 80 is true length of side 1 and

2 1/2 x 80 is true length of side 2 of room

Step-by-step explanation:

the area is side 1 x side 2 in sq inches

then change square inches to square feet for your final answer

Answer:

14000

Answer:

10.

Angle NSR, angle QSM, and angle PSM

11.

Angle QSR and angle QSM

12.

Angle MSR

13.

Angle NSM, angle PSR, and angle OSR

Step-by-step explanation:

10. Obtuse angles are greater than a 90 degree angle

11. Right angles make like a half square shape

12. Straight angles are like straight lines

13. Acute angles are less than 90 degrees 

Also, sorry I could do the ones with a protractor, I did not have one on hand lol

Answer:

[tex]2 + 3b[/tex]

Step-by-step explanation:

[tex]2b + (2 + b) \\ \\ 2b + 2 + b \\ 2 + 3b[/tex]

Answer:

The correct answer is A.

Answer:

Step-by-step explanation:

i think its A

Answer for Practice 8-4:

1. Right, Scalene

2. Acute, Isosceles

3. Obtuse, Scalene

4. Isosceles

5. Scalene

6. Equilateral

7. Scalene

8. Acute

9. Obtuse

10. Right

11. Right

12. This cannot be done because a right triangle always has two acute angles (cannot be right-angled and obtuse-angled at the same time)

14. Can't be done because a scalene triangle has no congruent sides, while isosceles triangles have two equal sides and two equal angles.
