Mathematics

Kamila [148]4 years ago

Answer:

4/9 and 1/64

Step-by-step explanation:

Do PEMDAS:

  1. Parentheses
  2. Exponents
  3. Multiplication
  4. Division
  5. Addition
  6. Subtraction

There are no parentheses or exponents, so move onto step 3 Multiplication

2 \div  \frac{3}{4}  \times 6

\frac{3}{4}  \times  \frac{6}{1}  =  \frac{18}{4}

2 \div  \frac{18}{4}  =  \frac{2}{1}  \times  \frac{4}{18}  =  \frac{8}{18}  =  \frac{4}{9}

4/9 is the answer to the first problem

Again there are no parentheses or exponents, so move onto multiplication

\frac{1}{2}  \div 4 \times 8

\frac{1}{2}  \div 32 =  \frac{1}{2}  \times  \frac{1}{32}  =  \frac{1}{64}

1/64 is the answer to the second problem

A woman’s age is three years more than twice her son’s age .the sum of their ages is 84. How old is the son ?
EleoNora [17]
Women age = 3 + 2 S (sons age) (three times more twice her sons age)
their age sum is 84
so women age + son age = 84
lets substitute the value of mothers age
3+2S+S=84
3S=84-3
3S=81
S=27
so sons age is 27

I need help ASAP. The cone shown has a 3 in radius and 7 in height. What is the volume of the composite figure?
erica [24]
Volume of a sphere is 4/3 pi r^3
Volume = 4/3 pi (3)^2
Volume = 113.1
But there is a half sphere so the volume will be 113.1/2 = 56.55


Volume of a cone = (1/3) pi x r^2 x h
Volume = 1/3 x pi x 3^2 x 7
Volume = 65.97

Total volume = 56.55 + 65.97 = 122.52 in^3

So the correct option is option B

2. Factor f(x) = x4 + x3 – 8x2 + 6x + 36 completely. Then sketch the graph.
arsen [322]
The complete factorization of f(x) = x4 + x3 – 8x2 + 6x + 36 is f(x) = <span>(x+2) (x+3) (x^2-4x+6).

See attached picture for the sketch of the graph of the function. To sketch the graph, simply substitute values of x into the function in order to get its specific values of f(x) = y. Plot these values in the cartesian plane. I hope this helped you a lot.</span>
