Step-by-step explanation:
the numbers of the problems =
12 × 25 = 300
each minute he can answer 2 problems
therefore, the time that he expect to finish the problems =
300/2 × 1 minute = 150 minutes
= 2 hours and 30 minutes
2 questions he can solve 1 min
per question he need 1/2min or 0.5min
Now

Answer:
16 * (cube root of 0.5)
Step-by-step explanation:
Radius of the big cone = 12 cm / 2 = 6 cm
Let r = radius of the small cone (cone of water), and h = the height of the small cone
Also, r / h = 6 / 16, so that h = (16/6)r = (8/3)r.
Thus, since the volume of the big cone = (1/3)π(r^2*h)=(1/3)π(6^2*16), and the volume of the small cone = (1/3)π(r^2*h)=(1/3)π(r^2*(8/3)r) = (1/3)π(r^3*(8/3)), and the volume of the small cone is half the volume of the big cone, we have that
(1/3)π(r^3*(8/3))=(1/2)((1/3)π(6^2*16))
(r^3*(8/3))=(1/2)((6^2*16))
r^3 = (3/8)(1/2)(6^2)(16)
r^3 = (1/2)(6^3)
r = (cube root of 1/2)(6),
and
h = (8/3)r = (8/3)(cube root of 1/2)(6) = 16(cube root of 1/2), the depth of the water.

Hello, need help on this Coordinate Math question please (:
Answer:
(8, 3)
Step-by-step explanation:
The first number (8) is our x, and we can see that this point is 8 units to the right. Then the second number (3) is our y, and we can see this is 3 as the point is 3 units up.
x = right or left
- right = positve
- left = negative
y = up or down
- up = positve
- down = negative
Answer:
B = (8, 3)
Step-by-step explanation:
In the ordered pair (x, y) of point B, (8, 3):
x = 8
y = 3
Hope this helps :)

A flying carpet flies 2.4 miles with the wind in the same amount of time it flies 1.4 miles against the wind. The wind speed is 4 mph. What is the speed of the flying carpet in still air?
Answer:
15.2 mph
Step-by-step explanation:
2.4÷(x+4)=1.4÷(x-4)
1.4(x+4)=2.4(x-4)
1.4x+5.6=2.4x-9.6
-x=-15.2

Noah and Amelia are reading the same book. At the beginning of the month, Noah was on page 41 and Amelia was on page 13. Noah will read 12 pages per day and Amelia will read 16 pages per day. Let NN represent the page of the book that Noah is on at the end of tt days into the month, and let AA represent the page of the book that Amelia is on at the end of tt days into the month. Write an equation for each situation, in terms of t,t, and determine whether Noah or Amelia is farther along in the book after 3 days.
Answer:
After 3 days, Noah is still farther along reading.
Step-by-step explanation:
Here are the two equations:
NN = 12tt + 41
AA = 16tt + 13
Now we plug in 3 to both equations to see what page they're on after 3 days:
[tex]NN = 12(3) + 41\\NN = 36 + 41\\NN = 77 \\\\AA = 16(3) + 13\\AA = 48 + 13\\AA = 61[/tex]
After 3 days, Noah is 77 pages along and Amelia is 61 pages along.
77 pages > 61 pages so therefore Noah is still farther along.

a scale drawing of Lafayette square is 8 inches long and 4 inches wide. The actual park is 160 feet wide. What is the actual area of the park, in square yards?
Answer:
Lafayette Square is about 5688.89 square yards
Step-by-step explanation:
The scale factor( ratio between the two sides) is 8 inches long to 4 inches wide or 2 to 1; 2 inches to one 1
Given the actual park is 160 feet wide ( need this measurement in inches).
so the actual part is 160 · 12 = 1920 inches wide.
Using the ratio long/ wide = long/ wide 2/1 = ?/1920. The part is 3840 inches long.
Answer need to be in yards: divide by 36 because 36 inches = 1 yard.
Long = 3840/36 = 320/3 yards
wide = 1920/36 = 160/3 yards
Actual area = L · W
= (320/3)·(160/3)
= 51200/9
= 5688.89 square yards

58,300 meters to kilometers. Round to the appropriate number of significant digits.
Answer:
58.3km
Step-by-step explanation:
58300 ÷ 1000 = 58.3km
Given:-
58,300 metres
Converting to kilometers, let's do by:-
[tex] \frac{58300 \: m}{1} \times \frac{1}{1000} km[/tex]
[tex] \frac{58300}{1000} [/tex]
[tex] => 58.3 \: km[/tex]
Therefore, in kilometers, 58300 m = 58.3 km.
