  1. If Kayla has a red ribbon with length 25  9 m and piece of 5 7 m is cut from it and gave to Sania . Find how much long ribbon left with her?                                                                                                                                                                                                                      
  • Kayla has a ribbon of length = 25 9 m.
  • Part of ribbon give to Sania = 5 7 m.
  • So, the length of the ribbon left =25 9 m - 5 7 m = 175  63 = 130  63 m
  • So , the ribbon left with Kayla is 2.06 m .

A box of popcorn weighs 15/16 pounds the box contains 1/3 butter popcorn and 2/3popcorn how much is a cheesy popcorn weigh
lyudmila [28]

Total weight of box of popcorn =15/16 pounds.

We are given two types of popcorns are there, butter popcorns and cheesy popcorns.

Butter popcorn is the one third of the total weight = 1/3 of Total weight

Plugging value of total wight, we get

= 1/3 * 15/16 = 5/16 pounds.

Cheesy popcorn = 2/3 of Total weight

Plugging value of total wight, we get

= 2/3 * 15/16 = 10/16 or 5/8 pounds.

Therefore, cheesy popcorn weigh is 5/8 pounds.

&({{ 5}}\quad ,&{{ 36000}})
\end{array}

\bf slope = {{ m}}= \cfrac{rise}{run} \implies 
\cfrac{{{ y_2}}-{{ y_1}}}{{{ x_2}}-{{ x_1}}}\implies \cfrac{36000-29400}{5-2}\implies \cfrac{6600}{3}
\\\\\\
2200
\\\\\\
% point-slope intercept
\stackrel{\textit{point-slope form}}{y-{{ y_1}}={{ m}}(x-{{ x_1}})}\implies \stackrel{y}{p}-29400=2200(\stackrel{x}{t}-2)
\\\\\\
p-29400=2200t-4400\implies p(t)=2200t+27200

how many in 2007?  well, 2007 is 7 years after 2000, thus set t = 7,to get p(t).
