The Williams budget 1/4 for rent and 1/3 for food. How much of their budget is left?

Flura [38]

Add the given fractions by finding the common denominator.

The common denominator of 3 and 4 is 12.

1/4 = 3/12

1/3 = 4/12

Now you can add them together: 3/12 + 4/12 = 7/12

Now subtract that from 1 to find the rest of the budget:

1 - 7/12 = 5/12

5/12 is left.

A population of beetles is growing according to a linear growth model. The initial population (week 0) is

Answer:

P=7.75t+13

t = 19 weeks

Step-by-step explanation:

Linear Modeling

Some situations can be modeled as linear functions. If we are in a situation where a linear model is suitable, then we need two sample points to make the model and predict future behaviors.

The linear function can be expressed in the slope-intercept format:

y = mx + b

Another equation of the line can be used when two points are given.

The equation of a line passing through points (x1,y1) and (x2,y2) can be written as follows:

$\displaystyle y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)$

The population of beetles is a situation where we must apply linear modeling. Two points are given. For time t=0, the population is P=13. The point is (0,13). For time t=8, P=75. The point is (8,75).

Find the equation of the line:

$\displaystyle P-P_1=\frac{P_2-P_1}{t_2-t_1}(t-t_1)$
