Answer:
Step-by-step explanation:
One pair of coordinates is sufficient to work out the constant of proportionality.
<u>Equation in general form:</u>
and
<u>Substitute x- and y- coordinates into equation and find the value of k:</u>
part A is just simple multiplication
since there are 2 6 sided number cubes there are 36 possible outcomes(6 sides *6 sides)
Part B is a little trickier. First off, you must find how to get seven.
1. 1+6 and 6+1
2. 2+5 and 5+2
3.3+4 and 4+3
therefore there are six combinations
you put that number over the total combos and get 6/36 or 1/6.
Hope this helps!
Answer: 2 1/4
Step-by-step explanation:
From the question, we are told that a recipe call for 3/4 c of chopped pecans
and that Brentt wants to triple the recipe .
The numerical expression that represents the amount of pecans he will need will be gotten by multiplying 3/4c by 3. This will be:
= 3 × 3/4c
= 9/4c
= 2 1/4
Answer:
t = 1.277 sec and t = 2.848 sec
Step-by-step explanation:
This problem is much more easily done by graphing it than by computing it using algebra.
The values of t we're looking for are the ones that make x = 0, so we want the solutions of 
on the interval [0, 3].
According to the graph, this is true when t = 1.277 seconds and t = 2.848 seconds.
This question is essentially asking you to find the surface area of the box.
The formula for SA on a rectangular prism is: 2(L*W+L*H+W*H)
L=Length W=Width H=Height
Lets input the information we know:
2(20*8+20*30+8*30)
Follow BEDMAS
2(160+600+240)
2(760+240)
2(1000)
2*1000
=2000
The box will need 2000 centimeters squared of material.
Hope this helps!
