5 1/6 divided by 7/10<br> (simplify and make a fraction)

True [87]

Answer:

$\frac{155}{21}$

Step-by-step explanation:

$5\frac{1}{6} = \frac{31}{6}$
Re-write the expression: $\frac{31}{6}$ ÷ $\frac{7}{10}$
31/6 ÷ 7/10 = 31/6 × 10/7
$\frac{31}{6}$ × $\frac{10}{7} = \frac{310}{42}$
310/42 = 155/21

I hope this helps!

Guided Practice

Schach [20]

Answer:

Ah! Geometric sequences, Eh? Sucks I know....

Step-by-step explanation:

So first, we need to find the factor of this(been a while since I have done this)

$r=\frac{24}{48} =\frac{1}{2}$

So we found the relationship! Now we find the entire equation.

So we know the first term, 96, so let's use it!

$a_{n} =96*(\frac{1}{2})^{n-1}$

So there is the equation!

Now to find the 10th term.

$a_{n} =96*(\frac{1}{2})^{n-1}\\a_{10} =96*(\frac{1}{2})^{9}\\a_{10} =96*\frac{1}{2^{9} } \\a_{10}=0.1875$

There you have it!

Hope this Helps!

P.S. Stay Safe!

A bakery makes small batches of bread daily. Each day, the bakery records the amount of flour used the number of loaves of bread

miv72 [106K]

Answer:

The slope of the line would be the constant of proportionality for the line

shown. The point (35, 49) is really close the line which would make the

constant of proportionality 49/35 = 7/5. The equation of the line would be y =

7/5x. The number of loaves of bread from 85 pounds of flour would be

7/5(85) = 119 loaves.
