Annabelle measured and recorded the amount of rainfall for 9 days in a row. Her results are shown below. 3/10in., 1/5in.,1/10in.
lapo4ka [179]

Answer:

Therefore,  the average amount of rainfall per day for the 8-day period is 0.2375in.

Step-by-step explanation:

We know that Annabelle measured and recorded the amount of rainfall for 9 days in a row. Her results are shown below. 3/10in., 1/5in.,1/10in., 3/10in., 2/5in., 1/5in., 1/5in., 1:5in.

We have 8 values given. So we will calculate the average value in 8 days.

We have

3/10+1/5+1/10+3/10+2/5+1/5+1/5+1/5=19/10

we get

\frac{19/10}{8}=0.2375

Therefore,  the average amount of rainfall per day for the 8-day period is 0.2375in.

Write the point-slope form of the equation of the line through the given point with the given
Marina86 [1]

Question 3)

Given

The point (1, -5)

The slope m = -5/6

Using the point-slope form of the equation of a line

y-y_1=m\left(x-x_1\right)

where

  • m is the slope of the line
  • (x₁, y₁) is the point

In our case:

  • m = -5/6
  • (x₁, y₁) = (1, -5)

substituting the values m = -5/6 and the point (1, -5) in the point-slope form of the equation of the line

y-y_1=m\left(x-x_1\right)

y-\left(-5\right)=-\frac{5}{6}\left(x-1\right)

y+5=-\frac{5}{6}\left(x-1\right)

Thus, the point-slope form of the equation of the line is:

y+5=-\frac{5}{6}\left(x-1\right)

Question 4)

Given

The point (-1, 5)

The slope m = -7/2

In our case:

  • m = -7/2
  • (x₁, y₁) = (-1, 5)

substituting the values m = -7/2 and the point (-1, 5) in the point-slope form of the equation of the line

y-y_1=m\left(x-x_1\right)

y-5=-\frac{7}{2}\left(x-\left(-1\right)\right)

y-5=-\frac{7}{2}\left(x+1\right)

Thus, the point-slope form of the equation of the line is:

y-5=-\frac{7}{2}\left(x+1\right)

Right Isosceles Triangle ABC has a hypotenuse of length h.
neonofarm [45]
The answer is a. 16x+h

Since a triangle is isosceles, its both legs are the same. So, we have two sides and a hypotenuse (a, a, and h)
A midsegment length (m) of a triangle is a half of a parallel bottom leg of the triangle (a):
a = 2m

The perimeter (P) of the triangle is the sum of its sides:
P = a + a + h

It is given:
m = 4x
Since a = 2m, we have:
a = 2*4x = 8x

Therefore, the perimeter is:
P = a + a + h = 8x + 8x + h = 16x + h
