Answer:

x =  8 hours

Step-by-step explanation:

add up all the parts,

the teachers spends 24 hours in a day to do 18 parts

there are 2 parts for grading per day, we need to solve for 3 days so 3*(parts) or 6 parts for grading

use ratio to solve for x,

24 hrs          x (hours)

______  =  __________

18 parts            3*(2 parts)

 

solve for x = (24 * 6 )/ 18 = 8 hours

What is the slope of the line that contains the points (-4,3) and (6,-3)
Naddika [18.5K]
\bf \begin{array}{ccccccccc}
&&x_1&&y_1&&x_2&&y_2\\
%  (a,b)
&&(~ -4 &,& 3~) 
%  (c,d)
&&(~ 6 &,& -3~)
\end{array}
\\\\\\
% slope  = m
slope =  m\implies 
\cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{-3-3}{6-(-4)}\implies \cfrac{-3-3}{6+4}
\\\\\\
\cfrac{-6}{10}\implies -\cfrac{3}{5}

Addison wants to cut 21 centimeters of lace, but her ruler is only calibrated in millimeters. How many millimeters of lace shoul
GuDViN [60]
We are given that Addison wants to cut 21 centimeters of lace. The question asks us to convert 24 centimeters into millimeters. However, to do that, we need to know how many millimeters are in a centimeter. There are 10 millimeters in a centimeter. Since centimeters are larger, we will need to multiply. Therefore, 21 × 10 is 210 millimeters, and that is how many millimeters Addison wanted to cut. Hope this helped and have a phenomenal day!

Find the midpoint of AB A.(-2,-3) B.(16,4) C.(-2,-11) D.(4,-10)
zheka24 [161]

Answer:

(-2,-1)

Step-by-step explanation:

Using the graph find the coordinates for A and B.

A (-4,2) and B is (0,-4)

Midpoint formula is (x1 + x2)/2 , (y1+y2)/2

x value of the midpoint= (-4+0)/2 = -2

y value of the midpoint= (2 + -4)/2 = -2/2= -1

Midpoint is (-2, -1)
