Answer:

32 degrees

Step-by-step explanation:

Because the triangle is isosceles, 2 of its angles must equal each other:

15x - 31 = 9x + 11

---> x = 7

Plug 7 into either 15x - 31 and 9x + 11:

15(7) - 31 = 74 degrees

and

9(7) + 11 = 74 degrees

Add them together, and you get 148 degrees.

Finally, subtract 180 from 148 to get 32 degrees for angle S.

HELP!! To find the quotient of two fractions, you first need to rewrite the division problem as an equivalent multiplication pro

sergey [27]

1. 5/6

2. 2/3 x 5/6

3. 2/3 x 5/6 = 10/18
Multiply the numerators— 2 x 5 = 10
Multiply the denominators—3x 6= 18

4. 10/18 = 5/9
Find the greatest common factor of 10 and 18 which is 2.
Divide the numerator by 2– 10/2 = 5
Divide the denominator by 2– 18/2 = 9

I hope this helps!

some friends plotted the locations of their house on a map. brianna's house is at (1,6), Jordan's house is at (5,3). What is one

Morgarella [4.7K]

Let
A (1,6)------> location brianna's house on a map
B (5,3)------> location Jordan's house on a map

we know that
One possible path from brianna's house to jordan's house it's a straight line ( the shortest distance)

using a graph tool
see the attached figure

find the distance points AB
d=√[(y2-y1)²+(x2-x1)²]-----> d=√[(3-6)²+(5-1)²]----> d=√[3²+4²]d=√25----> d=25 units

the distance from brianna's house to jordan's house is 25 units

Daniel [21]

Answer:

The player will not make the team.

Step-by-step explanation:

To find the percentage he is shooting, divide the number he has made by the number he has taken.

9/15 = 60%

60% is less than the needed 65%

natali 33 [55]

Answer:

See Below

Step-by-step explanation:

There are two runners that run at different average speeds, let these be Ra (runner a) and Rb (runner b). We also have two differnt distances that can be ran, let Leg A La and Leg b Lb. We get the equation bellow:

$Total time = L_a/R_1 + L_b/R_2$

Mickey = 35km/h

Minnie = 25km/h

Leg A = 30

Leg B = 20

Since Mickey is the fastes, he should run the section with the longest distance:

$Total time = L_a/R_1 + L_b/R_2\\Total time = 30_k_m/35_k_m_/_h + 20_k_m/25_k_m_/_h\\Total time = (30/35)_h + (28/35)_h\\Total time = (58/35)_h$
