Answer 1

Answer:

Answer:

19.8

Step-by-step explanation:

Estimate 3√43

There is a formula for estimating square root of non-perfect square numbers
√A²±B = A ± B/2A
where A² is the nearest perfect square, B is the difference between the original number and the perfect square

Using same formula, we'll estimate √43

43 = 36 + 7= 6² + 7
√43 = √(6² + 7) = 6 + 7/2*6 = 6.583 ≈ 6.6 rounded to nearest tenth

Answer to the original question:

3√43 = 3*6.6 = 19.8

A crew of highway workers paved 12 mile in 14 hour. If they work at the same rate, how much will they pave in one hour?

Answers

Answer:

0.857 miles in 1 hour

Step-by-step explanation:

It is given that,

A crew of highway workers paved 12 mile in 14 hour.

We need to find how much will they pave in 1 hour if they work at the same rate.

14 hours = 12 miles

To find how much they pave in 1 hour, we must divide 12 by 14 as follows :

$1\ \text{hour}=(12)/(14)\ \text{miles}\n\n=0.857\ \text{miles}$

Hence, they pave 0.857 miles in 1 hour.0.857 miles in 1 hour.

A student is trying to solve the set of two equations given below:Equation A: x + z = 6
Equation B: 3x + 2z = 1

Which of the following is a possible step used in eliminating the z-term?
Multiply equation A by −2.
Multiply equation B by 2.
Multiply equation A by 3.
Multiply equation B by 3.

Answers

a possible step used in eliminating the z-term is "multiply equation A by −2."

x + z = 6
3x + 2z = 1

x + z = 6 / *(-2)
3x + 2z = 1

-2x - 2z = -12
3x+ 2z = 1

-2x + 3x -2z +2z = -12 +1
x = -11

-11 + z = 6
z = 6 + 11
z = 17

Answer:Multiply equation A by -2 is correct everyone

A coin is tossed and a fourth section spinner is spun once a tree diagram shows the possible outcomes for the two events what is the probability of flipping tails on a coin and spinning a two on the spinner

Answers

Answer:

2/6 or 1/3 I think

Step-by-step explanation:

you have a 1 out of 2 chances to land tails and 1 out of 4 chance to role a 2 on the spinner. so in total there is 6 chances for rolling and flipping the coin. and there is only 1 chance for both in the odds.

therefore I believe that its is 1/3 or 2/6. I do not know if I am right exactly but that is my thought process.
