Two angles form a linear pair. the measure of one angle is 26∘26∘ greater than the measure of the other angle. find the measure
Tpy6a [65]

A linear pair means that the sum of the angles is 180 degrees.

Therefore:

a + b = 180°

 

We know that:

a = b + 26°

 

Therefore:

b + 26 + b = 180

2b = 154

b = 77°

 

So,

a = b + 26 = 103<span>°</span>

Quan is inviting 3 friends to a party. Each friend wants 8 cookies and each box has 6 cookies.How many boxes should Quan get?
Anastasy [175]
First, figure out how many total cookies you need. You do this by multiplying the number of friends times the number of cookies each friend will get.

8 x 3 = 24

Then, you take the number of cookies and divide it by the number in each box to find the number of boxes you need.

24/6 = 4

Quan should get 4 boxes.

Suppose a set of data about the spread (in hundreds of acres) of a food-borne bacteria (after t weeks) in lettuce has the follow
Alexxandr [17]

Answer:

A sinusoidal model would be used

The kind of function that have consistency in the periodic rate of change is the Average rate of changes

Step-by-step explanation:

The type of model that would be used is sinusoidal model and this is because there is periodic change in the values given ( i.e the rate of changes given )

For percentage rate of changes :

starting from 0.9% there is an increase to 1.3% then a decrease to 1.1% and a further decrease to 1% before an increase to 1.3% and another decrease to 1%

For Average rate of changes:

starting from 2.9 there is a decrease to 2.4, then an increase to 3.7 and another decrease to 3.1 followed by an increase to 3.6 and a decrease back to 3.2

This relation ( sinusoidal model ) is best suited for a linear model because there is a periodic rate of change in the functions

The kind of function that have consistency in the period rate of change is the Average rate of changes
