Angle MNO is formed by segments MN and NO on the following coordinate grid:
Eva8 [605]

Answer:

I am 90% sure that the answer is M'N'O' is 90*

Step-by-step explanation:

A line segment MN is shown as M = -1,1 and N= -5,4 this makes a diagonal line across the grid. Another line segment NO is shown with O as ordered pair negative 1, 4. Angle MNO is rotated 90 degrees counterclockwise about the origin to form angle M′N′O′. this is where the angles meet, Rotating the shape (or the angles) does not change the degree of the angle of the shape. I am 99% sure that an 90* angle would be formed. but im just in middle school so what do i know?

The table shows the height of a softball that Hallie threw in the air. Is the relationship shown linear? Why or why not?
andrew11 [14]

Answer:

Not a linear relationship

Step-by-step explanation:

Given

The attached table

Required

Linear or not

To do this, we simply calculate the slope of the table at different intervals.

Slope (m) is calculated as:

m = \frac{y_2 - y_1}{x_2 - x_1}

Let:

(x_1,y_1) = (0,0)

(x_2,y_2) = (0.5,7.2)

So, the slope is:

m = \frac{y_2 - y_1}{x_2 - x_1}

m = \frac{7.2 - 0}{0.5-0}

m = \frac{7.2}{0.5}

m = 14.4

Let:

Let:

(x_1,y_1) = (1,10.7)

(x_2,y_2) = (2,12.2)

So, the slope is:

m = \frac{y_2 - y_1}{x_2 - x_1}

m = \frac{12.2 - 10.7}{2 - 1}

m = \frac{1.5}{1}

m = 1.5\\

See that the calculated slopes are not equal.

Hence, it is not linear

Problem: How many cubic yards of concrete must be ordered to pour the section
timama [110]

Answer:

0.9 yd³

Step-by-step explanation:

Information given:

Length = 18 ft

Width = 1.5 ft

Height = 1 ft

What to find/do:

First, convert the measurement from feet to yards. (3 ft = 1 yard)

Length = 18 ft = 6 yd

Width = 1.5 ft = 0.5 yd

Height = 1 ft = 0.3 yd

Next, find the volume of the shape given. The volume would give us the amount of concrete to use in yards.

Formula for volume = L*W*H

Plug in the values into the formula

V = 6*0.5*0.3 = 0.9 yd³

0.9 cubic yard of concrete must be ordered to pour on the given section.

Area of the volume

Trinomials can be factored into two sets of binomials. Always, sometimes, or never?
MAXImum [283]
Trinomials are polynomials that contain three(3) terms. A trinomial can sometimes be factored into two binomial and sometimes, it cannot be factored at all. In factoring, the each term in the trinomial equation affect the capability of it to be factored. Thus, trinomial are can be sometimes be factored into two sets of binomials.
