This is a special right triangle and the hypotenuse is √2 as long as legs (a).
a √ 2 = 15
a = 15 : √ 2 = 15 : 1.4142135 = 10.6066 ≈ 10.6

What is the slope of a line perpendicular to the line of y=-1/4x-1
harina [27]

Answer: 4

The given line has a slope of -1/4 as this is the number in front of the x. The general equation y = mx+b has m as the slope. So m = -1/4 is given

Flip the sign to get -1/4 turn into +1/4 or just 1/4

Then flip the fraction (aka reciprocal) to go from 1/4 to 4/1 and that simplifies to 4.

Multiplying the original slope (-1/4) and the perpendicular slope (4) will result in -1.

Find the value of x<br><br>m&lt;2= 10x + 10<br>​
jarptica [38.1K]

Answer:  x = 12

<u>Step-by-step explanation:</u>

a) Linear Pair: 110° + ∠a = 180°  -->    ∠a = 70°

b) congruent sides implies congruent angles  --> ∠b = 70°

c) Triangle Sum Theorem: ∠a + ∠b + ∠c = 180

                                         70° + 70° + ∠c = 180°

                                                            ∠c = 40°

d) Complimentary Angles: ∠c + ∠d = 90°

                                          40° + ∠d = 90°

                                                   ∠d = 50°

∠2) Linear Pair: ∠d + ∠2 = 180°

                         50° + ∠2 = 180°

                                  ∠2 = 130°

x) m∠2 = 130°

   10x + 10 = 130°

   10x        = 120

       x        = 12

Im. lost plese help I suck at Unit Rates
Makovka662 [10]
Luke: 2 miles in 40 minutes, 20 minutes a mile, (2/40 = 20 minutes a mile)
Luke's speed is 3 miles an hour (60minutes/20minutes a mile = 3miles).

Sally: 0.05 miles a minute, 60 minutes in an hour, 60 x 0.05 = 3 miles an hour.  Or 0.05 miles a minute, 40 minutes walked, 40 x 0.05 = 2 miles walked.

There are a few other ways to show that they are accurate rates. 

So yes, they are both correct rates.
