Answer:
x = 7 , y = 7
Step-by-step explanation:
A 45- 45- 90 triangle is an isosceles right triangle with the 2 legs being congruent , that is
x = 7
Using Pythagoras' identity in the right triangle, then
y² = 7² + 7² = 49 + 49 = 98 ( take square root of both sides )
y =
=
=
×
= 7
The inequality is 4 ≥ x/2.1, and the answer is 8.4 ≥ x (or x ≤ 8.4).
To solve this, we multiply both sides by 2.1:
4*2.1 ≥ x
8.4 ≥ x.
Answer:
Monthly household expenditures on groceries
Step-by-step explanation:
The response variable is the one for which measurements are desired and that depends on other variables.
In this case, family size, household income, and household neighborhood are independent variables, while the response variable is the monthly household expenditures on groceries.
Option D is the correct answer

Further explanation:
Let

The perimeter of a rectangle is given by:

It is also given that:

So we can write as

We also know that The length of the rectangle is three times its width

Putting the value of l in the inequality

Rearranging the terms

Hence, option D is the correct answer.
