Answer:
68
Step-by-step explanation:
The expression is given as:
4( 3+ 7y) + 6(2 - y)
It is known that y is equal to 2. Therefore, substitute 2 in for y.
4(3+7(2))+6(2-2)
Now, solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction
Solve inside of the parentheses first.
4(3+7(2))+6(2-2)
4(3+14)+6(0)
4(17)+6(0)
Multiply
68+0
Add
68
Answer:
132
Step by step
11×12 is 132 and 132 is a 3 digit number and made up of three different numerals and is divisible by 11.
Answer:
12/99
Step-by-step explanation:
x=0.121212
100x=12.121212
100x-x=12.1212-0.1212
99x=12
x= 12/99
The solution of the value is mathematically given as
√6 =2.449
This is further explained below.
<h3>What is square Root?</h3>
Generally, In mathematics, the term "square root" refers to a component of a number that, when multiplied by itself, results in the same value as the original number.
As an example, both 3 and –3 are square roots of the number 9.
A number y is said to have a square that is equal to a given number x if and only if it satisfies the following condition: y2 = x.
Another way to express this is to say that the number y has the same value as its own square. For example, the square roots of 16 are 4 and -4, since 42 divided by 2 is 16.
In conclusion,
√6 is not -4
because
√6 =2.449

Answer:
Find the cube's volume first (because it's the simplest figure) by using the formula;
(Formula for vol. of cube)
V =
Where 's' stands for <u>one side</u> of the <u>cube</u> raised to the <u>power of three</u>.
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 );
V =
V = 3^3 → (The symbol ' ^ ' means to the power of.)
V = <u>27</u>, 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:
<u>Length = 3</u>
<u>Width = 3</u>
Height = 3(we won't use)
- What we know of the dimensions for the pyramid:
<u>Height = 4</u>
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 = <u>12</u>, is the volume of the pyramid.
Add your volumes:-
27(cube vol.) + 12(pyramid vol.)
= <u>39</u> is the volume for this whole solid, your answer is D.
