Find the area of triangle ABC

1 answer:

ANEK [815]3 years ago

8 0

let X = (-1, 0)

let Y = (1,0)

Area ABC = Area (AXB - AXY + CBY)

Area AXB = 5×4/2 = 10

Area AXY = 5×2/2 = 5

Area CBY = 2×2/2 =1

Area ABC = 10-5+1 = 6units sq

Julia has 4 gallons 2 quarts of water.Ally needs the same amount of water but only has 12 quarts.How much more water does Ally n

ozzi

Ok so what do we know :

4 quarts = 1 gal
Julia has 4gal and 2 quarts or 18 quarts
ally has 12 quarts

so if julia has 18 quarts and ally has 12 that means that ally needs 6 more quarts (or 1gal 2 quarts) so that she and julia can have the same amount

Since they both have the same variables, just add the numbers and get 13. So therefore it is 13x

Step-by-step explanation:

1)......mean= sum of observations/ total observations

= 5.2+8.4+4.3+6.7+5.8/5= 6.08

median= n=5(odd)=n+1/2=6/2=3rdterm= 5.8( when arranged in ascending order).....

mode= 3median- 2meam= 3×5.8-2×6.08= 5.24

range=8.4-4.3=4.1(when done A.O)

2)......mean= -2-13-13-5-7/5= -8

median= 3rd term= -5.....(n=5..odd)(when done A.o)

mode=largest frequency= -13

range= -13-(-2) = -13+2= -11(A.O)

3).....mean= sum/no.= 8+6+13/2+17/2+15/2+7+8+11/2+7+8//10=7.2

median=n=10(even)

=

mode= 8

range=8.5-5.5=3

median:==

(10/2)+(10/2+1)//2=5 term + 6term/2=7+7.5=14.5/2=7.25

4)....

5)...remove 62...then 73will be having highest frequency

Someone help please and thank you!

Answer:

$\boxed{11\frac{1}{3}}$

Step-by-step explanation:

$\text{Number of stones} = \frac{\text{Length of path}}{ \text{ Length of each stone}}\\$

$= 2\frac{5 }{ 6} \div \frac{ 1}{ 4}\\$

Convert the mixed number to an improper fraction

$2\frac{5 }{ 6} \div \frac{ 1}{ 4} = \frac{17}{6}\div\frac{ 1}{ 4}\\$

Invert the denominator and change division to multiplication

$\frac{17}{6}\div\frac{ 1}{ 4} = \frac{17}{6}\times \frac{ 4}{ 1}\\$

Cancel the 2s

$\frac{17}{6}\times \frac{ 4}{ 1} = \frac{17}{3}\times \frac{ 2}{ 1}\\$

Multiply numerators and denominators.

$\frac{17}{3}\times \frac{ 2}{ 1} = \frac{ 34}{ 3}\\$

Convert the improper fraction to a mixed number.

$\frac{ 34}{ 3} = 11\frac{1}{3}\\$

It takes $\boxed{11\frac{1}{3}}$ stones to complete the path.
