Bradley sold at least 127 juices and coffees. He sold 9 more juices than coffees. What is the minimum amount of coffees Bradley could have sold? Enter your answer in the box.

59 coffees

Step-by-step explanation:

c + j >= 127

j = 9 + c

c + 9 + c >= 127

2c + 9 >= 127

2c >= 127-9

2c >= 118

c=59,

check by 59× 59 + 9 = 127

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

you estimate that the angle of elevation to the top of the 86th floor (the observatory) is 82 .the total height of the building is another 123 meters above the 86th floor.
