Answer:K=10

Step-by-step explanation:

When I multiply 4 times 10+(5)=45

When I multiply 6 times 10 + 10=70

So when I add them together (45+70)=115

Answer:

10

Step-by-step explanation:

Exterior angle = sum of interior angles

115 = (4k + 5) + (6k + 10)

115 = 10k + 15

100 = 10k

k = 10

line pass through the line (-3, -7.5)tahila determined that the equation of line n is y=0.5x explain the error tahila made while
Tasya [4]

The equation of the line will be (assuming the y-intercept equal to zero):

y = 2.5*x

<h3>What is Tahila's mistake?</h3>

We know that we have a linear equation of the form:

y = a*x + b

Such that we know that the line passes through (-3, -7.5), notice that the proposed equation is:

y = 0.5*x

If you evaluate that in -3, you get:

y = 0.5*-3 = -1.5

So this line does not pass through (-3, -7.5).

If we assume that b = 0 in the linear equation, then we can find the value of a as:

-7.5  =  a*-3

a = 7.5/3 = 2.5

Then the linear equation is:

y = 2.5*x

The baseball diamond is really a square. The distance between each of the bases is 90 feet. How far does the catcher have to thr
Zina [86]
A^2 + b^2 = c^2

base lines: home to first is a, first to second is b, home to second is c.

90^2 + 90^2 = c^2
or
\sqrt{ {90}^{2}  +  {90}^{2} }  = c
c = 127.28
