Which number has the same value as 28 tans
Answer:
Each hotdog is $3 and each drink is $4.
Step-by-step explanation:
Let h be the number of hotdogs and d the number of drinks,
7h + 5d = 41
4h + 8d = 44
Let's eliminate h. Multiply the first by 4 and the second by 7.
28h + 20d = 164
28h + 56d = 308
Subtrat the first from the second.
36d = 144
d = 4
Substitute back into one of the equations.
7h + 5(4) = 41
7h + 20 = 41
7h = 21
h = 3
Answer:
The answer is D - 242 inches.
Step-by-step explanation:
One inch bigger would be 5'8" and 4'5". These must be added twice, which equals 20'2". 20 feet is equal to 240 inches plus 2 more inches = 242 inches.
Answer:
Step-by-step explanation:
The missing figure is attached.
The volume of grain that could completely fill this silo is the sum of the volume of the cylinder and the volume of the hemisphere.
By definition, the volume of a cylinder can be calculated with this formula:
Where "r" is the radius and "h" is the height.
In this case you know that:
And the volume of a hemisphere can be found using the following formula:
Where "r" is the radius.
In this case:
Therefore, the volume of grain that could completely fill this silo, rounded to the nearest whole number, is:
