1) carrots= 5/12 peas= 2/12 potatoes=1/12
corn= 4/12
2) there are more carrots than peas. there are more corn than potatoes.
3) 2/3
4) separate like number 3 but instead of corn put carrots and leave the peas.
To do this you need to work backwards. if you note the number as 'n' you can put
7n = 5600
to find n you simply divide both sides by 7 getting
n = 5600/7
n = 800
This is an awful question. They mean to say the number of hours practicing <em>per week</em> (we'll call it h) varies inversely with the <em>time</em> (t) she runs her event. Unless they mean to imply more practicing makes Tyler slower, in which case she should just get a pizza.
Inverse variation means the product is a constant, we'll call it k.
ht = k
When h = 1 hour t=6 minutes
(1)(6) = k
k = 6 (hour*minutes, but as long as we're consistent we don't need to sweat the unit.)
Decreasing her time by one minute means t = 6 - 1 = 5. We solve for h.
ht = k
h = k/t = 6/5 = 1.2 hours
Answer: 1.2 hours, second choice
Answer: 8.3 ounces
Step-by-step explanation:
simple, there's a flat fee for 1 ounce, then 23 cents for each ounce following.
so $2 - $0.32 = $1.68
1.67 / 0.23 = 7.3 ounces
7.3 ounces + 1 ounces (from the flat fee we subtracted)
which equals 8.3
