Answer:
y = 4
Step-by-step explanation:
Given that y varies jointly with x and z then the equation relating them is
y = kxz ← k is the constant of variation
To find k use the condition y = 16 when x = 4 and z = , that is
16 = k × 4 × = 2k ( divide both sides by 2 )
8 = k
y = 8xz ← equation of variation
When x = 2 and z = , then
y = 8 × 2 × = 16 × = 4
Step-by-step explanation:
3x + 2y = 8
2y= -3x+8
y= -3/2x+4
so the answer is m= -
m=− 2

Pizzas are circles, and the formula to find the area of a circle is r²π=a.
The diamter split in half can easily show you the radius, so let's solve the first portion of this question.
14÷2=7
7²=49π≈ 153.94
Now, there are two large pizzas. We have to multiply by 2.
153.94×2= 307.88
So there's about 307.88² inches of pizza.
Answer:
In mathematics, a ratio is a comparison of two or more numbers that indicates their sizes in relation to each other.
Step-by-step explanation:
A ratio compares two quantities by division, with the dividend or number being divided termed the antecedent and the divisor or number that is dividing termed the consequent.
The change of base formula allows you to write a logarithm in terms of logarithms with another base. It follows this pattern,
where a≠1 and b≠1
Assigning the base to be 7,
