Answer:

≈ 1468.59223 in squared

Step-by-step explanation:

1) A=2AB+(a+b+c)h

2) AB= square root of s(s﹣a)(s﹣b)(s﹣c)

3) s=a+b+c / 2

4) A=ah+bh+ch+1 / 2 square root of﹣a4+2(ab)2+2(ac)2﹣b4+2(bc)2﹣c4

5) 18·22+18·22+18·22+1 / 2 x the square root of ﹣184+2·(18·18)2+2·(18·18)2﹣184+2·(18·18)2﹣184≈1468.59223

≈ 1468.59223 in squared

Hope this helps :)

Find the quotient.<br><br>5 over 7 divided by 7 over 10

raketka [301]

Answer:

$\frac{5}{7}\div \frac{7}{10}=\frac{50}{49}$

Step-by-step explanation:

$\frac{5}{7}\div \frac{7}{10}$

$\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{a}{b}\div \frac{c}{d}=\frac{a}{b}\times \frac{d}{c}$

$=\frac{5}{7}\times \frac{10}{7}$

$\mathrm{Multiply\:fractions}:\quad \frac{a}{b}\times \frac{c}{d}=\frac{a\:\times \:c}{b\:\times \:d}$

$=\frac{5\times \:10}{7\times \:7}$

$\mathrm{Multiply\:the\:numbers:}\:5\times \:10=50$

$=\frac{50}{7\times \:7}$

$\mathrm{Multiply\:the\:numbers:}\:7\times \:7=49$

$=\frac{50}{49}$

Therefore,

$\frac{5}{7}\div \frac{7}{10}=\frac{50}{49}$

Answer:

The complete table will be:

x y

1 5

0.8 4

0.4 2

Step-by-step explanation:

Given rule is:

y = 5x

In the given rule, x is multiplied by 5 to get the values of y. The same rule can be manipulated to find the value of x in terms of y.

$\frac{y}{5} = \frac{5x}{5}\\x = \frac{y}{5}$

Putting y = 5

$x = \frac{y}{5}\\x = \frac{5}{5}\\x = 1$

Putting y = 4

$x = \frac{y}{5}\\x = \frac{4}{5}\\x = 0.8$

Putting y = 2

$x = \frac{2}{5}\\x = 0.4$

Hence,

The complete table will be:

x y

1 5

0.8 4

0.4 2
