On a particular day, the wind added 5 miles per hour to Alfonso's rate when he was cycling with the wind and subtracted 5 miles

Nata [24]

now, this is pretty much the same as the one before it with Jaime, so I'll do this without much fuss.

recall d = rt.

a = Alfonso's rate

with the wind his speed is a + 5, against it is a - 5, 60 miles with it and 30 miles against it, all in the same time of t hours.

$\bf \begin{array}{lcccl} &\stackrel{miles}{distance}&\stackrel{mph}{rate}&\stackrel{hours}{time}\\ &------&------&------\\ \textit{with the wind}&60&a+5&t\\ \textit{against the wind}&30&a-4&t \end{array} \\\\\\ \begin{cases} 60=(a+5)t\implies \frac{60}{a+5}=\boxed{t}\\\\ 30=(a-4)t\\ -------------\\ 30=(a-4)\left( \boxed{\frac{60}{a+5}} \right) \end{cases} \\\\\\ 30(a+5)=(a-4)60\implies 30a+150=60a-240 \\\\\\ 390=30a\implies \cfrac{390}{30}=a\implies 13=a$

At a bake sale there were 52 items sold total. If 24 of the items sold were cookies and the rest were brownies what is the ratio

Radda [10]

52=24 + b
to find b, you just subtract (52-24)
28 to 24 is our ratio
we can simplify this (just like fractions!) since both are even, let’s do it by 2!
28/2 = 14 and 24/2 = 12
simplify once more and you get our ANSWER: 7:6

the scientist's collection that has granite that weighs 74 26/36 lbs, marble that weighs 63 16/34 lbs, and quartz that weighs 81

Viktor [21]

Answer:

(D)6 1/2 lbs

Step-by-step explanation:

$\text{Weight of the quartz = }81 \dfrac{9}{40} \text{ lbs}\\\dfrac{9}{40}=0.225 \\$Therefore:$ 81 \dfrac{9}{40} \approx 81.25\text{ lbs (to the nearest 1/4 lbs)}\\\text{Weight of the granite = }74 \dfrac{26}{36} \text{ lbs}\\ \dfrac{26}{36}=0.722 \\$Therefore:$74 \dfrac{26}{36} \approx 74.75\text{ lbs (to the nearest 1/4 lbs)}$
