Write your own word problem and share it with the group. Then translate your problem into its resulting math equation. What step

Ainat [17]

Step-by-step explanation:

Word Problems are mathematical problems presented in complete languages, rather than in mathematical notations.

Example:

A certain number is divided by half, the result is added to itself to give 6, what is the number?

Solution:

- Let the number be x

- Divide x by half:

In word problem, extra caution is to be taken, as misinterpretation can be very chaotic. Dividing a number by 2, is totally different from dividing the number by half.

4 divided by 2 is 4÷2 = 2

4 divided by half is 4÷½ = 4×2/1 = 8

2 and 8 are different, reason to be cautious.

So dividing x by half, we have:

x ÷ 1/2 = x × 2/1 = 2x.

- Now, what we have is

2x + x = 6

Solving this equation, we can obtain the value of x.

2x + x = 6

3x = 6

Dividing both sides by 3

3x/3 = 6/3

x = 2.

Therefore, the solution to the word problem is x = 2.

If we apply the Pythagorean Theorem to the Egyptian knots we can see that 3^2 + 4^2 = 5^23 2 +4 2 =5 2 . Which of the sets of th

pantera1 [17]

Answer:

B) { 51, 149, 140 }

C) { 16, 63, 65 }

Step-by-step explanation:

We need to choose Pythagoras theorem formula

$c^2=a^2+b^2$

now, we can verify each options

option-A:

a=1

b=1

c=1

now, we can verify formula

$1^2=1^2+1^2$

$1=2$

We can see that left side is not equal to right side

so, this is FALSE

option-B

a=51

b=140

c=149

now, we can verify formula

$149^2=51^2+140^2$

$22201=22201$

We can see that left side is equal to right side

so, this is TRUE

option-C

a=16

b=63

c=65

now, we can verify formula

$65^2=16^2+63^2$

$4225=4225$

We can see that left side is equal to right side

so, this is TRUE

option-D:

a=6

b=8

c=11

now, we can verify formula

$11^2=6^2+8^2$

$121=100$

We can see that left side is not equal to right side

so, this is FALSE

I need answer for this quick please

Anna007 [38]

Answer:

- 6

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

$\frac{f(b)-f(a)}{b-a}$

Here [ a, b ] = [ - 1, 4 ] , then

f(b) = f(4) = 4³ - 6(4)² - 4 = 64 - 96 - 4 = - 36

f(a) = f(- 1) = (- 1)³ - 6(- 1)² - (- 1) = - 1 - 6 + 1 = - 6 , then

average rate of change = $\frac{-36-(-6)}{4-(-1)}$ = $\frac{-36+6}{4+1}$ = $\frac{-30}{5}$ = - 6

Find the volume of this sphere. Round to the nearest tenth.<br><br>plz help me!!!

raketka [301]

Answer:

523.6 cm^3

Step-by-step explanation:

We know the diameter is 10. The radius is half the diameter, so 10/2=5.

Knowing the radius is 5, we just need to plug it into the formula.

Volume=(4/3)pi5^3

≈523.6

Answer:523.6 cm^3
