Answer:

Step-by-step explanation:

b = 21 is the base, a is the height

area = 0.5ab = 210

ab = 420

a = 420/b = 420/21 = 20 ft

length of hypotenuse = √(a²+b²) = √(20²+21²) = √841 = 29 ft

$\text {Hi! To solve this problem you must...}$

$\text {Do Keep Change Flip (KCF):}$

$\text {Keep: -3/8}$

$\text {Change: / into *}$

$\text {Flip: 1/2 into 2/1}$

$\text {Your new problem should be -3/8*2/1}$

$\text {The Final Step is to Multiply:}$

$\text {Note: When Multiplying Fractions you multiply Numerator by Numerator}$

$\text {and Denominator by Denominator}$

$\text {-3/8*2/1=}$

$\fbox {-6/8}$

$\text {Best of Luck!}$

Answer:

5√5

Step-by-step explanation:

Use the distance formula:

d = √((x2 -x1)² +(y2 -y1)²)

d = √((-7-(-2))² +(-7-3)²) = √((-5)² +(-10)²) = √(25 +100)

d = √125 = √(25·5)

d = 5√5 . . . . distance between the points

4 3/4 divided by 1 1/6

ozzi

Answer:

$2\frac{13}{22}$

Step-by-step explanation:

$=\frac{19}{4}\div \frac{11}{6}$

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

$=\frac{19}{4}\times \frac{6}{11}$

$=\frac{19}{2}\times \frac{3}{11}$

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

$=\frac{19\times \:3}{2\times \:11}$

$\mathrm{Multiply\:the\:numbers:}\:19\times \:3=57$

$=\frac{57}{2\times \:11}$

$\mathrm{Multiply\:the\:numbers:}\:2\times \:11=22$

$=\frac{57}{22}$

$=2\frac{13}{22}$
