How do you find the perimeter of triangle ABC? - 1

Answers

Answer 1
Answer: Alright, so we'll use the Pythagorean Theorem for this one. 
⇒ a²+b²=c² 

The hypotenuse of  a triangle is represented by c² and we're given the values for a and b.  For this triangle, we'll make 15 = a and 20 = b.  Plug this into the equation and we'll have (15)² + (20)² = c ².  This gives us 625 = c².  Solve for c by square rooting both sides of the equation.  √(625) = c.  We now know that c = 25.  To take the perimeter, we add a + b + c ⇒ (15) + (20) + (25) = Perimeter.

-Hope this helps!
Answer 2
Answer: do the Pythagorean Theorem - a^2+b^2=c^2

20^2+15^2=c^2
400+225=c^2
625=c^2
sqrt(625)=c
c=25

Add all of the sides up and you get 25+15+20=60

Scott has 1/3 of the computer games as Anish, and Anish has 1/2 as many games as Nick. Together they have 140 games. How many do they have each?Scott has......
Anish has......
Nick has......

Answers

Scott = Anish ÷ 3 or 1/3 Anish
Anish = Nick ÷ 2 or 1/2 Nick
S + A + N = 140
1/6 N + 3/6 N + 6/6 N = 10/6 N (140)
10/6 N = (140)
140 ÷ 10 = 1/6 N (14) = Scott
9/6 N (126) - 3/6 (42 = Anish) = N = 84
S = 14
A = 42
N = 84

CHECK?

14 = 1/3 of 42
42 = 1/2 of 84
14 + 42 + 84 = 140 :)
let x = # of computer games nick has
then
Anish has    1/2x games
and
Scot has  1/2*1/3   = 1/6x  games
 thus
1/6x + 1/2x + x  =  140
1/6x + 3/6x + x  = 140
10/6x = 140
10x =140* 6
   x       =      84  >        Nick
  1/2x    =    42  >    Anish
   1/6x    =   14    >    Scot

On a Saturday, the ratio of the amount of water used by household A to the amount of water use by household B was 13 : 5. Household A used 260 gallons of water for that day. Find the total amount of water used by the two household on that Saturday.

Answers

Answer:the total amount of water used by the two households on that Saturday is 360 gallons

Step-by-step explanation:

Let x represent the total amount of water used by the two households on that Saturday. On that Saturday, the ratio of the amount of water used by household A to the amount of water use by household B was 13 : 5. The total ratio is 13 + 5 = 18

The amount of water used by household A would be

13/18 × total amount of water.

The amount of water used by household B would be

5/18 × total amount of water.

Since household A used 260 gallons of water for that day, it means that

13/18 × x = 260

13x = 260×18 = 4680

x = 4680/13 = 360

The equation of the line of best fit of a scatter plot is y = 12x + 7. What is the slope of the equation? −12 −7 12 7

Answers

Well,

Slope-intercept form is given as follows:
y = mx + b

In this equation, "m" is the slope, and "b" is the y-intercept.

y = 12x + 7

We can clearly see that the 12 in the equation is the "m" in the general slope-intercept form.

Therefore, the slope of the equation is 12.

Find the result when 90 is decreased by 35%.
58.5
75.6
60.5
78.5

Answers

In this question, it's asking you to find the number when 90 is subtracted by 35%. So, you find 35% of 90 which is 31.5 and you minus it from 90 = 58.5.

> 90 x 35% = 31.5
> 90 - 31.5 = 58.5
