Answer:
The heaviest baby have to gain to reach a healthy level by 42 ounces.
Step-by-step explanation:
It is said that the 500-gram babies are going to have to make four times their weight [to reach a healthy level].
So, the healthy level of weight is (500 × 4) = 2000 gm i.e. 2 kg.
Now, 1 kg is equivalent to 35.274 ounces.
So, 2 kg will be equivalent to (35.274 × 2) = 70.548 ounces.
So, the heaviest baby with weight 28.6 ounces have to gain weight to reach a healthy level by (70.548 - 28.6) = 41.948 ounces ≈ 42 ounces. (Answer)
Answer:
m = 6
Step-by-step explanation:
Here, we want to find the value of m
To do this, we use the indices addition property for multiplication
On the left hand side;
5^(2 + m + 7) = 5^15
5^(m + 9) = 5^15
since the bases are equal, we equate the powers
m + 9 = 15
m = 15-9
m = 6
A direct variation equation is one that requires y varies directly as x and looks like this in equation form:
where k is the constant of variation. If we solve this for y, we have y = kx, which happens to be a linear function... a line. k here, then, serves as the slope. So what we are given as points on a direct variation function are actually points on a line. The equation for this requires that we find the slope and then rewrite the formula accordingly. First the slope:
Now we need to write the equation by using one of the points' coordinates. I picked the first point that has an x coordinate of -9 and a y coordinate of -3. Fitting those into the slope-intercept form of a line,
which simplifies to
-3 = -3 + b and b = 0. That means that the equation of direct variation is
