If we use the rules we say that <span>when we multiply two numbers we get the result in the numbers the least significant number has in the multiplication. So we may proceed like this:</span>

67.6 x 1.2 = 81.12 

<span>As the decimal part does not continue indefinitely we can leave the answer as it is.</span><span> if the answer was 81.123612356213 then we leave it like </span><span>81.1 as the rules say</span>

Juan sells banana bread by weight. He cuts a 1-lb loaf of banana bread into 6 equal slices. He wants to complete the table showi
Westkost [7]

Answer:

0.1\frac{}{6}

Step-by-step explanation:

When Juan cut a 1 lb loaf of banana bread into 6 slices, the weight of each slice forms a repeating decimal. A repeating decimal is a decimal number with repeating digit/s.

i.e \frac{1}{6} = 0.166666666666666...

To express the total weight for each slice, he should write a bar over 6 to show that the number repeats.

i.e \frac{1}{6} = 0.1\frac{}{6}

Note that \frac{}{6} has expressed that the division has 6 as the repeating digit in the decimal number.

Is 3/4 and 20/28 equivalent?
Mila [183]
No, because simplified, 20/28 would be 5/7, not 3/4
21/28 would be equivalent to 3/4 though

Answer:

  4.097 s

Step-by-step explanation:

The formula for ballistic motion usually used is ...

  h(t) = -4.9t² +v₀t +s₀

where v₀ and s₀ are the initial vertical velocity and height, respectively. Here, we have v₀ = (35 m/s)sin(35°) and s₀ = 0. We want to solve for h(t) = 0.

  0 = -4.9t² +35sin(35°)t = t(-4.9t +35sin(35°))

This is true for t=0 and for ...

  t = 35sin(35°)/4.9 ≈ 4.09697 . . . seconds

It will take about 4.097 seconds for the projectile to reach the ground.

Desmos has a setting option for angles in degrees. That is what we used here.
