The variable you wanted to find wasn’t mentioned, so I solved for all three:
5xy + n = 12
5xy = 12 - n
x = 12-n/5y
y = 12-n/5x
n = 12 - 5xy
Answer:
The volume of tank to the nearest cube is 503 ft³
Step-by-step explanation:
Given that,
Diameter of tank = 8 ft
radius = 4 ft
Height = 10 ft
We need to calculate the volume of tank
Using formula of volume
Where, r = radius
h = height
Put the value into the formula
Hence, The volume of tank to the nearest cube is 503 ft³
Answer:C) Children cannot use counters for the initial amount.
Step-by-step explanation:Problem solving allows students to use mathematical concepts, skills and the relationships among them to solve problem situations with different levels of difficulties. Problem solving framework allows students to solve mathematical situations by assisting them to handle or approach problem solving systemically.
There are basically four structures they are
(1) Join
(2) Separate
(3) Part-Part-Whole
(4) Compare.
JOIN AND SEPARATE STRUCTURES INCLUDE ACTIONS THAT INCREASE OR DECREASE A QUANTITY.
The part-part whole does not involve an action but it has a relationship between a particular whole and its two separate parts.
The compare structure also does not involve an action,but it compares two unconnected and distinct sets.
