Ms.Bass gave her class 12 minuets to read. Carrie read 5 1/2 pages in that time. At what rate, in pages per hour, did Carrie rea

Talja [164]

So, we have

5.5/12

Convert to a denominator of 60, since there are 60 mins in an hour

60/12= 5

Multiply numerator and denominator by 5

5*5.5= 27.5

12*5= 60

So our answer is 27.5/60 or 27.5 pages an hour

I hope this helps :)

Shawna and her best friend Keisha go shopping. The function p(t) = 3x +2x-4x2+ 21 represents how much money each girl spent base

NNADVOKAT [17]

Answer:

$\$30$

Step-by-step explanation:

we have

$p(t)=3x+2x-4x^{2}+21$

<em>Find the amount of money that each girl spent</em>

For t= 2 hours

$p(2)=3(2)+2(2)-4(2)^{2}+21$

$p(2)=10-16+21$

$p(2)=\$15$

<em>Find the amount of money that they spend together</em>

Multiply by 2 the amount of money that each girl spent

$(2)\$15=\$30$
