Answer: -3x/8 - 1/4
Hope this helps, good luck!
We know that
area of the composite figure=area of the rectangle+area of semicircle
area of rectangle=b*h
b=10 ft
h=6 ft
area rectangle=10*6----> 60 ft²
area of semicircle=pi*r²/2
r=6/2----> 3 ft
area of semicircle=pi*3²/2-----> 14.13 ft²
area of the composite figure=[60+14.13]-----> 74.13 ft²-----> 74 ft²
the answer is
74 ft²
Answer:
Step-by-step explanation:
a). A baker uses 5.5 pounds of flour daily.
That means he uses 88 pounds of flour daily.
Therefore, number of ounces of flour used in two week (14 days) = 88×14 = 1232 oz
b). If recipe for a loaf of bread calls for 12 oz of flour
Therefore, in two weeks number of loves baked = 102.67 ≈ 103
c). Baker can ship a pack of 15 loaves of bread in a box.
Therefore, number of boxes =
=
= 6.84
minimum number of boxes which can be exported will be 6.
d). The baker pays for sugar = $0.80 per pound
and paid for butter = $1.25 per pound
Then the expression for 6 pounds of butter and 20 pounds of sugar will be
= 0.80(pounds of sugar) + 1.25(pounds of butter)
= 0.80(20) + 1.25(6)
= 16 + 7.5
= $23.5
e). Chocolate sprinkles costs = $0.80 per pound
Total cost for 100 pounds of chocolate sprinkles = 100×0.80 = $80
th of $80 =
=$8

The 3.1 °F/min rate of change of the temperature and 15 minutes change duration gives the change in temperature as 46.5 °F
<h3>How can the change in temperature be found from the rate of change?</h3>
The rate at which the temperature changed = 3.1 °F/min
The duration of the change in temperature = 15 minutes
The relationship between the change in temperature, the rate of change in temperature and the time can be presented as follows;
Where;
∆T = The required change in temperature
∆t = The duration of the change = 15 minutes
Which gives;
∆T = 3.1°F/min × 15 minutes = 46.5 °F
- The change in temperature, ∆T = 46.5 °F
