Slope between (-2,11) 5,6)

Mathematics

madreJ [45]3 years ago

Answer:

-\frac{5}{7}

Step-by-step explanation:

Slope = \frac{rise}{run}

          = \frac{6-11}{5-(-2)}

          = \frac{6-11}{5+2}

          = \frac{-5}{7}

          = -\frac{5}{7}

Answer:

To calculate the slope, you can first substract the points to get the vector that join both, you may do it like this:

(-2, 11) - (5,6) = (-2 - 5, 11 - 6) = (-7, 5)

To get the slope when you get the vector (x,y), you will have to divide y be x:

5/-7

So the slope is 5/-7, -\frac{5}{7}

If 1/3 of a gallon of paint covers 1/9 of a gate, then how many gallons of paint are needed to cover the entire gate?
xxMikexx [17]

Answer:

3 gallons of paint

Step-by-step explanation:

If 3/4 of a gallon covers 2/5 of a wall, this means that a half of 3/4 gallons can cover 1/5 of a wall.

By knowing this, you can just make up your own expression

(the trick is to find a way to break it down to one, so you can multiply and manipulate it to save yourself some brain cells)

1/5+1/5+1/5+1/5+1/5= whole wall if  3/4/2=3/8  = amount of paint to cover 1/5 wall, then  (3/8)⋅5=3/8+3/8+3/8+3/8+3/8=15/8≈1.875

since we're talking about real life it would be 2 gallons of paint instead of 1.875 gallons to paint the whole wall

Calculate the ratios in the table using the side lengths that you recorded in Part C.
Strike441 [17]

Step-by-step explanation:

The ratios are;

\dfrac{BC}{AB} = \dfrac{3}{5}

AB

BC

=

5

3

\dfrac{AC}{AB} = \dfrac{4}{5}

AB

AC

=

5

4

\dfrac{BC}{AC} = \dfrac{3}{4}

AC

BC

=

4

3

\dfrac{DE}{AD} = \dfrac{3}{5}

AD

DE

=

5

3

\dfrac{AE}{AD} = \dfrac{4}{5}

AD

AE

=

5

4

\dfrac{DE}{AE} =\dfrac{3}{4}

AE

DE

=

4

3

koGiven that the lengths of the sides are;

\overline {AB}

AB

= 20

\overline {BC}

BC

= 12

\overline {AC}

AC

= 16

\overline {AD}

AD

= 10

\overline {DE}

DE

= 6

\overline {AE}

AE

= 8

The ratios are;

\dfrac{Length \ opposite \ \angle A}{Hypothenus} = \dfrac{BC}{AB} = \dfrac{12}{20} = \dfrac{3}{5}

Hypothenus

Length opposite ∠A

=

AB

BC

=

20

12

=

5

3

\dfrac{Length \ adjacent\ \angle A}{Hypothenus} = \dfrac{AC}{AB} = \dfrac{16}{20} = \dfrac{4}{5}

Hypothenus

Length adjacent ∠A

=

AB

AC

=

20

16

=

5

4

\dfrac{Length \ opposite \ \angle A}{Length \ adjacent \ \angle A} = \dfrac{BC}{AC} = \dfrac{12}{16} = \dfrac{3}{4}

Length adjacent ∠A

Length opposite ∠A

=

AC

BC

=

16

12

=

4

3

\dfrac{Length \ opposite \ \angle A}{Hypothenus} = \dfrac{DE}{AD} = \dfrac{6}{10} = \dfrac{3}{5}

Hypothenus

Length opposite ∠A

=

AD

DE

=

10

6

=

5

3

\dfrac{Length \ adjacent\ \angle A}{Hypothenus} = \dfrac{AE}{AD} = \dfrac{8}{10} = \dfrac{4}{5}

Hypothenus

Length adjacent ∠A

=

AD

AE

=

10

8

=

5

4

\dfrac{Length \ opposite \ \angle A}{Length \ adjacent \ \angle A} = \dfrac{DE}{AE} = \dfrac{6}{8} = \dfrac{3}{4}

Length adjacent ∠A

Length opposite ∠A

=

AE

DE

=

8

=
