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

b² - 5c if b = 15 and c = 9
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

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.

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.

-(w+4)+2(4w-4)
help plz :’)
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

PLEASE HELP!!!!!!!!!!!!!!!!
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)

Can somebody explain how to find an area of a square?
Please note that the area's side lengths are all the same.
(The side lengths are all 1/3 or also known as 0.3333)
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.
