Answer:
depends on whether you meant (1/2)/4 or 1/ (2/4)
Step-by-step explanation:
1/2 x
---------- = -------------
4 28
Using cross products
1/2* 28 = 4x
14 = 4x
Divide by 4
14/4 = 4x/4
7/2 =x
If you meant
1 x
---------- = -------------
2/4 28
1 * 28 = 2/4 x
28 = 1/2 x
Multiply each side by 2
28*2 = 1/2x*2
56 =x
Answer:
1.96 smaller pizzas can fit into the larger pizza.
Step-by-step explanation:
Area of smaller pizza:
π × (10/2)^2 = π × 5^2 = 25π square inches
Area of larger pizza:
π × (14/2)^2 = π × 7^2 = 49π square inches
Ratio of area of larger pizza to area of smaller pizza: 49π / 25π = 1.96
Answer: The possible side lengths are either 16 inches or 20 inches
Step-by-step explanation: The aquarium is in the shape of a cube which suggests that, all dimensions (length, width and height) are equal.
If it can hold 4096 cubic inches of water, then the volume of water in it can be calculated as follows;
Volume = L x W x H
Knowing that all three dimensions are the same the formula can be re-written as;
Volume = L³
4096 = L³
Add the cube root sign to both sides of the equation
∛4096 = ∛L³
16 = L
Also if it can hold up to 8000 cubic inches of water, then the volume of water in it can be calculated as;
Volume = L³
8000 = L³
Add the cube root sign to both sides of the equation
∛8000 = ∛L³
20 = L
Therefore, if the aquarium can hold between 4096 and 8000 cubic inches of water, then the side lengths are either 16 inches or 20 inches
The change of the weather balloon would be 90% increase. to get the percentage of change we have to subtract 50 ft to 95 ft, it will then give us the 45 ft change. Then we have to divide 45 ft by 50 ft times 100, it will give us 90%. Then since the change and percentage of change is positive then the change could be describe as increasing.
