164x + 24(2x) < = 4240
164x + 48x < = 4240
212x < = 4240
x < = 4240/212
x < = 20
for a dog.....2x = 2 * 20 = 40.....so it costs 40 per dog and 20 per cat
The value of x can be found by adding the two angles and setting them equal to 180 because they are on a straight line.
3h + 18 + 15h = 180
18h + 18 = 180
18h = 162
h = 9
So the value of h is 9
Answer:
The height of the cup is 0.51 in.
The height of the cup is 4.59 in.
Step-by-step explanation:
The volume of the cylinder is 
Given that,
The volume of the cup is 14.4375 in³.
If the measuring cup has a radius of 3 in.
Then,
Plug r= 3 in.
⇒h=0.51 in.
The height of the cup is 0.51 in.
If it has radius of 1 in.
Then,
Plug r= 1 in.
⇒h=4.59 in.
The height of the cup is 4.59 in.
Answer:
0.5
Step-by-step explanation:
It is less than 0.6.
Answer:
The average speed on level road is 65 mph
Step-by-step explanation:
Let the speed on the winding road be x mph
So the speed on the straight road will be x +20 mph
Mathematically, distance = speed * time
Distance on level road will be;
(x + 20)2
Distance on winding road will be;
x* 4 = 4x
Thus, we have;
2(x + 20) + 4x = 310
2x + 40 + 4x = 310
6x + 40 = 310
6x = 310 - 40
6x = 270
x = 270/6
x = 45 mph
The average speed on the level road is x + 20
That will be 45 + 20 = 65 mph
