Answer:
y = 1/4x - 2
Step-by-step explanation:
y = 1/4x + b
-1 = 1/4(4) + b
-1 = 1 + b
-2 = b
Answer:
3:25 pm
Step-by-step explanation:
The distance between New Orleans and Houston is : 353 miles
Departure time of the bus : 12:20 pm
Speed of the bus: 60 mph
After 45 minutes, the bus will be at a distance of : 45/60 * 60 = 45 miles
Distance remaining to cover = 353-45 = 308 miles
Speed of the motorcycle = 72 mph
Relative speed = 60 + 72 = 132 mph
Time the two will meet = 308 / 132 = 7/3 hrs
7/3 hrs = 2 hrs 20 minutes
Time the two will meet is ;
12:20 pm + 45 minutes + 2 hrs 20 minutes
= 3:25 pm
Midpoint formula: (x1+x2/2 , y1+y2/2)
So, (-1+3/2 , 9+8/2)
-2/2 = -1 17/2 = 8.5
Answer: (-1,8.5)
Answer:
The price for adults would be $44.20
Step-by-step explanation:
There are 2 ways to solve this problem
1) You can multiply 26 by 0.7 and then add That to 26
Or
2) You can just multiply 26 by 1.7
You get the same answer for both ways
So first way
26*0.7 is 18.2
Now add 18.2 to 26
You’ll get 44.20
Second way
26*1.7. I multiplied by 1.7 becuase its a markup of 70 percent, th kid’s price is already 100 percent and for adult its an extra 70 percent so the china ally we’re paying 170 percent for the adult ticket
Now multiplying by 170 percent is basically the diamond 1.7
so 26*1.7 is 44.2
Answer:
Option B is correct.
Weight of a bowling ball is 5.24 Ib
Step-by-step explanation:
Assume: The shape of the bowling ball is perfectly spherical.
Given:
Radius of a bowling ball= 5 inches (r) .
One cubic inch weighs th of a pound.
Density of a bowling ball =
Volume of sphere is given by:
where V is the volume and r is the radius of the sphere.
Substitute the value of r =5 and in above we get;
Simplify:
To find the weight of a bowling ball:
Then;
Therefore, the weight of a bowling ball ≈ 5.24 Ib
