(a) Find the linear equation that relates the temperature t and the number of chirps per minute n.
If the equation is linear, then the equation should have the form of t = mn + b
m = (80 - 70) / (168 - 120) = 5/24
t = 5/24n + b
70 = 5/24(120) + b
b = 45
t = 5/24 n + 45
<span>(b) If the crickets are chirping at 138 chirps per minute, estimate the temperature. (Round your answer to the nearest degree.)
</span><span>t = 5/24 n + 45
</span><span>t = 5/24 (138) + 45 = 74 </span>°F
1 yard = 3 feet
300 yards = (3 ft) x (300) = 900 feet
<em>1,000 feet</em> is larger than 900 feet. It's also longer and farther.
the bus goes 65 miles every hour. so: 1hr = 65mi
to find how many miles it goes every 2.5 hours, we multiply each side by 2.5:
2.5hrs = 162.5mi
Answer:
I think the answer is B, tell me if it is wrong.
There are 16 ounces in a pound. 3 x 32= 96
96/16=6
Lucy made 6 pounds of cake. Hope this helped!
