Answer:
The number of questions in sixth assignment must be less than or equal to 28.
Step-by-step explanation:
The number of questions in first five assignments are 11,10,13,14 and 14.
It is given that Mrs hawk assigns her students an average of no more than 15 questions on each assignment. Therefore the average of six assignments is less than or equal to 15 questions.
Let the number of questions in sixth assignment be x
Average of six assignments are
Since the average of questions is no more than 15, therefore
Therefore the number of questions in sixth assignment must be less than or equal to 28.
Answer and Explanation:
Given the function:
ℎ(t)= −16t+5t+250
Where the variable t is measured in seconds. We can plug in t=20 seconds in the function to measure the height in feet of the bungee jumper after 20 seconds.
h(t)= -16×20+5×20+250
h(t)= -320+100+250
h(t)=350-320
h(t)= 30feet
height in feet of the bungee jumper after 20 seconds = 30 feet
Answer: $786 (approx)
Step-by-step explanation:
Given: The amount of money Susan saved for computer= $500
Let x be the cost of the computer.
Since, she have to pay 70 % of the cost of the computer thus, we have the following equation
70% of x=$500
Thus, she can afford a computer of cost $786
Answer:
8/7/100 0_0
Step-by-step explanation:
Answer:
The answer is 20ft
Step-by-step explanation:
Since they both cast shadows at the same time, the ratios of their height to their respective shadow length will be the same.
Hence; we'll equate both ratios to find the length.
House= 12/9
Flag pole= h/15
Equating both:
12/9 = h/15
h x 9 = 12 x 15
h = 180/9
h = 20ft
