A 100 centimeter stick broke into 3 pieces one piece was 7 centimeters long and another was 34 centimeters long how long was the third piece

Answers

Answer 1
Answer: The third piece is 59 cm long. 

Add the first two pieces up. 7+34= 41. Since the whole stick is 100 cm long, subtract 41 from 100 to find the length of the third piece. 100-41=59. 
Answer 2
Answer:

Answer:

59 cenitmeters

Step-by-step explanation:

34+7=41

100-41=59.

How do you do this problem 3x times x squared

Answers

both variables are x

pretend there is an imaginary 1 in front of the x for x squared

3 x 1 = 3

x^2 x X = x^3

this is because when multiplying numbers with the same variable like this problem for instance then you add the squared (2) with the x ( imaginary 1)

so 3x^3 is the answer



The expression 3x times x squared simplifies to 3x³.

We have,

To simplify the expression 3x times x squared, you can multiply the coefficients and combine the variables.

The expression can be written as: 3x * x^2

To multiply the coefficients, you multiply 3 and 1, which gives you 3.

To combine the variables, you multiply the x term and the x² term.

When multiplying variables with the same base (in this case, x), you add the exponents. So, x * x^2 can be simplified as x^(1+2) = x^3.

Putting it together, the expression 3x times x squared simplifies to 3x³.

Thus,

The expression 3x times x squared simplifies to 3x³.

24 written as a percentage

Answers

Any number is equal to that number over 1

So x is equal to x/1

Same thing with 24. 24 = 24/1

To get it into percent we multiply by 100 so:

\sf{(24)/(1)=(24*100)/(1*100)}

And simplifying that we get

\sf{(2400)/(100)}

And x/100 = x%

so 2400/100 = 2400% 

So your answer is 2400% :)

How can you use a point on the graph of f –1(x) = 9x to determine a point on the graph of f(x) = log9x?

Answers

The first option is correct

Answer:

Switch the x- and y-coordinates

Step-by-step explanation:

Students in Miss Moseley's fourth grade class are learning multiplication, and they demonstrate mastery by passing assessments. Travis has passed 11 tests, and his classmate, Jenifer, has passed 2 tests. Going forward, Travis plans to pass 2 tests per week. Meanwhile, Jenifer plans to pass 5 tests per week. Eventually Jenifer will catch up to Travis. When the number of tests each student has passed are equal, how many tests will each student have passed and how many weeks will it take?

Answers

Answer:
Each will have passed 17 tests and it will take 3 weeks.

Explanation:
Let x be the number of weeks.
The number of tests Travis passes to begin with is 11.
We then add 2 tests per week, or 2x to that, giving us:
11+2x.

The number of tests Jenifer has passed to begin with is 2.
We then add 5 tests per week, or 5x to that, giving us:
2+5x.

Setting these equal, we have:
11+2x=2+5x.

Subtract 2x from each side:
11+2x-2x=2+5x-2x;
11=2+3x.

Subtract 2 from each side:
11-2=2+3x-2;
9=3x.

Divide both sides by 3:
(9)/(3) =  (3x)/(3);
3=x.

It will take 3 weeks.
In 3 weeks,
Travis will have passed:
11+2*3 = 11+6 = 17 tests.
Jenifer will have passed the same number, since she catches up with him at this point.

Answer:

Each will pass 17 test after 3 weeks.

Step-by-step explanation:

Consider the provided information,

Let x is the number of weeks.

Travis has passed 11 tests and plans to pass 2 tests per week.

11+2x

Jenifer, has passed 2 tests and plans to pass 5 tests per week.

2+5x

Now equate them as shown.

11+2x=2+5x

11-2=5x-2x

9=3x

x=3

Hence, after 3 weeks both have passed the same number of test.

Substitute x=3 in 11+2x

11+2(3)=17

Hence, each will pass 17 test after 3 weeks.
