Answer:
z = 42
Step-by-step explanation:
The question can be answered in 2 steps as follows:
Step 1: Calculation of the constant of the variation
The equation for the joint variation can be given as follows:
z = cxy ................... (1)
Where;
z = 60
c = constant = ?
x = 5
y = 6
Substituting the values into equation (1) and solve c, we have:
60 = c * 5 * 6
60 = c * 30
c = 60 / 30
c = 2
Step 2: find z when x = 7 and y = 3
Since from Step 1 c = 2, we now use equation (1) and substitute the values into it to find z as follows:
z = 2 * 7 * 3
z = 42
Answer:
The answer is 3.
Explanation:
Factors of 18:
1, 2, 3, 6, 9, 18.
Factors of 21:
1, 3, 7.
The highest number that both sets contain is 3, so the GCF will be 3.
Copernicus proposed a heliocentric model in which the earth revolved around the sun, not the other way, and this went against what the church was saying at the time: the church, which insisted it is always right, said that the sun revolver around the earth.
The correct answer is: <span>C. His scientific discoveries undermined the power of the Church. </span>
Answer:
a. -6
b. +6
c. -6
Step-by-step explanation:
minus times plus times plus = -
minus times minus times plus = +
minus times minus times minus = -
1 times 2 times 3 = 6
so:
-1 times 2 times 3 = -6
-1 times -2 times 3 = +6
-1 times -2 times -3 = -6
