Answer:

The two solutions: 7/8 & 0.92

Step-by-step explanation:

$\frac{5}{7} =0.714$

7/8 = 0.875, because 0.875 $\geq 0.714$

0.92 because $\geq$ 0.714

Hope this helps

Answer:

Your answer would be the first one, <u>7/8 and 0.92</u>, because they are only ones greater than 5/7 the rest equal under 5/7

Answer:

Step-by-step explanation:

2 easy ways:

1. Divide 7 by 3 then multiply by 2

7/3= seven thirds or 2.333

Now multiply by two to get 14 thirds

or 4.666

2. Multiply 7 by 2/3, or 0.666

This way is a lot easier with a

calculator

The weight of the box is 14/3’s or 4.666

Given sin(−θ)=1/5 and tanθ=√6/12 .

Natasha_Volkova [10]

Answer:

B). −2√6/5

Step-by-step explanation:

tan theta = sin theta/ cos theta

Multiply each side by cos theta

tan theta * cos theta = sin theta

Divide each side by tan theta

cos theta = sin theta/ tan theta

We know that the sin (- theta) = - sin theta since sin is and odd function

sin theta = - ( sin (-theta))

Putting this into the above equation,

cos theta = - ( sin (-theta)) / tan theta

cos theta = - 1/5 / (sqrt(6)/12)

Remember when dividing fractions, we use copy dot flip

cos theta = -1/5 * 12/ sqrt(6)

cos theta = -12/ (5 sqrt(6))

We cannot leave a sqrt in the denominator, so multiply the top and bottom by sqrt(6)/sqrt(6)

cos theta = -12/ (5 sqrt(6)) * sqrt(6)/sqrt(6)

cos theta = -12 sqrt(6) / 5*6

Simplify the fraction.

cos theta = -2 sqrt(60/5

Helena is baking a cake that requires three and one-half cups of flour. Helena accidentally poured five and one-sixth cups of fl

RUDIKE [14]

Amount of flour Helena accidentally poured $=5\frac{1}{6} =\frac{31}{6}$ cups of flour.

Amount of flour the cake requires $=3\frac{1}{2} =\frac{7}{2}$ cups of flour.

Amount of flour that Helena should take out $=\frac{31}{6} - \frac{7}{2}$

$=\frac{31}{6} - \frac{7 \times 3}{2\times 3}$

$=\frac{31}{6} - \frac{21}{6}$

$=\frac{31-21}{6}$

$=\frac{10}{6}$

$=\frac{5}{3}$

$=1\frac{2}{3}$ cups of flour.
