Answer:
30
Step-by-step explanation:
16 days is 16/80 = 1/5 the time for 6 builders, so the number of builders required is 1/(1/5) = 5 times that:
5 × 6 builders = 30 builders
g(x) is the inverse of f(x)
Answer:
Step-by-step explanation:
Sum of angle in a triangle = 180°
<A+<B+<C = 180
Given <B = 50°
Substituting into the formula
<A+50+<C = 180
<A+<C = 180-50
<A+<C = 130°
Since the ∆ABC is an acute triangle, the angles <A and <C must be angles less than 90° since acute angles are angles less than 90°
The possible values of <A and <C that will be acute and give a sum of 130° are;
∠A= 58° and ∠C= 72°
∠A= 80° and ∠C= 50°
∠A= 60° and ∠C= 70°
You can see that all the Angles are less than 90° and their sum is 130°
The response variable in the study that Ann has done here can be said to be Time spent exercising.
<h3>What is a response variable?</h3>
This is the name that is used to refer to the dependent variable. This is the variable that is of interest in the study. The goal is to see the changes that occurs in the particular variable based on the actions that another variable would have such as the independent variable.
From this we can see that The response variable in the study that Ann has done here can be said to be Time spent exercising.
