  • Answer:

<em>w = 21 feet</em>

<em>l = 63 feet</em>

  • Step-by-step explanation:

<em>l = 3w</em>

<em>P = 2(l + w)</em>

<em>168 = 2(l + w) : 2</em>

<em>84 = l  + w</em>

<em>replace l</em>

<em>84 = 3w + w</em>

<em>4w = 84</em>

<em>w = 84 : 4</em>

<em>w = 21 feet</em>

<em>l = 3w</em>

<em>l = 3×21 feet</em>

<em>l = 63 feet</em>

Which best explains whether a triangle with side lengths 2in , 5in , 4in. is an acute triangle
lutik1710 [3]
So we know that 3,4 and 5 are pythagorean triplet and these result from a right triangle sides length 
- than 3,4 and 5 mean right triangle so 2,5 and 4 mean acute triangle sure or you can prove it in this way too
- than 3^2 +4^2 =5^2 => a right triangle so than 
2^2 +4^2 < 5^2 => an acute triangle

PLEASE HELP!!!!!!! A family has two cars. The first car has a fuel efficiency of 35 miles per gallon of gas and the second has a
Marianna [84]

Answer:

The answer to your question is car 1 = 30 gal and car 1 = 20 gal

Step-by-step explanation:

car 1 = a

car 2 = b

Efficiency of car 1 = 35 mi/gal

Efficiency for car 2 = 20 mi/gal

Total distance = 1450

Total gas consumption = 50 gal

Equations

                          35a + 20b = 1450            ------- (I)

                             a   +     b =  50               ------- (II)

Solve by elimination

Multiply equation II by -35

                          35a  + 20b  = 1450

                         -35a  - 35b   = -1750

Simplify

                            0    - 15b    =  -300

Solve for b

                                        b =  -300/-15

Result

                                        b = 20

Substitute b in equation II to find a

                               a +  20  = 50

Solve for a

                               a  = 50 -20

Result

                               a  = 30

Please help solves asap
Anon25 [30]

Answer:

8=41

7=49

10=41

9=49

Step-by-step explanation:

angle 8 is given and since 7 and 8 make 90 then 7 =49 because 90-41=49. 10 and 8 are the same size (at least it looks like it) therefore 7 and 9 are the same too. So that is how I got the answers.
