2/3 of the product of 3/8 and 16

Answers

finding the product of 2 numbers means that you have to multiply those numbers

(3)/(8) * 16

when multiplying fractions , numerators are multiplied by numerators and denominators by denominators

(3)/(8)*(16)/(1)  = (3*16)/(8*1) = (48)/(8) = 6

therefore product of 3/8 and 16 is 6

next we have to find 2/3 of 6

'of' operator means multiplication

(2)/(3) *(6)/(1) = (2*6)/(3*1) = (12)/(3) = 4


answer is 4

4

Further explanation

The Problem:

  • (2)/(3) of the product of (3)/(8) and 16.
  • Write an expression to match and then evaluate.

The Process:

Here are some early expressions that need attention.

  • two-thirds is (2)/(3)
  • three-eights is (3)/(8)
  • the product of (3)/(8) and 16 is (3)/(8) * 16

The term of "the product" is synonymous with multiplication.

Let us write an expression to match for (2)/(3) of the product of (3)/(8) and 16.

\boxed{\boxed{ \ (2)/(3) * \bigg( (3)/(8) * 16 \bigg ) \ }}

And now we evaluate the full expression.

\boxed{ \ = (2)/(3) * \bigg( (3)/(8) * 16 \bigg ) \ }

We can cross out 8 and 16.

\boxed{ \ = (2)/(3) * (3 * 2) \ }

\boxed{ \ = (2)/(3) * 6 \ }

We can cross out 3 and 6.

\boxed{ \ = 2 * 2 \ }

Thus, the result is 4.

Quick Steps:

\boxed{ \ (2)/(3) * (3)/(8) * 16 \ }

\boxed{ \ (1)/(1) * (1)/(4) * 16 \ }

\boxed{ \ (16)/(4) \ or \ 16 / 4 \ }

\boxed{\boxed{ \ 4 \ }}

41.77=r^3 find the original equation is 175=4/3 (pie) r^3

Answers

Hello!

I am assuming we want to find r. To do so we just find the cube root of 41.77, which is about 3.47.

Therefore, r is about 3.47.

I hope this helps!

If a 35 ft rope is cut into two sections with one section 6 times as long as the other section, how long is the shorter piece?

Answers

Answer: 5 feet

Step-by-step explanation:

Given: The total length of the rope = 35 feet

Let the length of the shorter section be x, then the longer section would be 6x.

According to the question, we have

x+6x=35\n\n\Rightarrow7x=35\n\n\Rightarrow x=(35)/(7)\n\n\Rightarrow x=5\ feet

Also, 6x= 6(5)=30\ feet

Hence, the  length of the shorter section = 5 feet

x is the first section soit the second is 6x
and x + 6x = 7x = 35 ft => x = 5 ft

Can some one help me on this plz

Answers

step 1
switch x and y
[x=-3y+27]

step 2
solve for y in steps
[x-27=-3y]

step 3 another solving
[(x-27)/-3=y]

step 4 simplify
[-1/3x+9=y]
(since -27/-3=+9)
