the pet store sells dog food at the same price per pound six pounds of dog food costs 4.50 alana needs to purchase 10 pounds of food
use the table to find the cost of 10 pounds of dog food.
cost (dollars): 4.50 ?
dog food (lb): 6 10
To find the cost of 10 pounds of dog food, we need to find the cost per pound first.
Cost per pound = Total cost / Total pounds
Cost per pound = $4.50 / 6 pounds
Cost per pound = $0.75 per pound
Now, we can calculate the cost of 10 pounds of dog food:
Cost of 10 pounds of dog food = $0.75 per pound x 10 pounds
Cost of 10 pounds of dog food = $7.50
Therefore, the cost of 10 pounds of dog food is $7.50.
the childrens play area at the community pool holds a total of 3185 gallons of water it takes 2.5 hours to fill the pool with 1625 gallons of water
use the table to find the amount of time it takes to fill the pool with 3185 gallons of water.
water (gal): 1625 3185
time (h): 2.5 ?
To find the amount of time it takes to fill the pool with 3185 gallons of water, we can set up a proportion using the given information:
Let x be the time it takes to fill the pool with 3185 gallons of water.
We know that:
1625 gallons of water is filled in 2.5 hours.
3185 gallons of water will take x hours (what we are trying to find).
So our proportion is:
1625 gallons / 2.5 hours = 3185 gallons / x hours
To solve for x, we can cross multiply:
1625 * x = 2.5 * 3185
1625x = 7962.5
Now, divide by 1625 to solve for x:
x = 7962.5 / 1625
x ≈ 4.9
Therefore, it takes approximately 4.9 hours to fill the pool with 3185 gallons of water.
a speed skater completes a 500 meter race in 40 seconds a cheetah runs 260 meters in 10 seconds how do their speeds compare?
find the number of meters a speed skater and a cheetah travel in 1 second.
a speed skater travels ? meters per second
a cheetah travels ? meters per second
To find the speed of the speed skater and the cheetah in meters per second, we need to calculate the distance they cover in 1 second.
Speed is calculated as distance divided by time.
For the speed skater:
Distance = 500 meters
Time = 40 seconds
Speed of the speed skater = 500 meters / 40 seconds = 12.5 meters per second
For the cheetah:
Distance = 260 meters
Time = 10 seconds
Speed of the cheetah = 260 meters / 10 seconds = 26 meters per second
Therefore, the speed of the speed skater is 12.5 meters per second and the speed of the cheetah is 26 meters per second.
To compare their speeds, we can see that the cheetah is faster than the speed skater.
complete the statement
a ? (speed skater or cheetah) travels ? meters per second faster than a ? (speed skater or cheetah)
