Answer:
7.
8.
Step-by-step explanation:
Given:
Three sides of the triangles are given.
For Question 7
1/2 _ 1/3 _1/5
For Question 8
0.1 _ 0.15 _ 0.2
We need to use >, <, and + signs to write inequalities for the relationships among the sides of the triangles.
Solution:
Part 7.
Property of the triangles.
Sum of two side of triangles must be greater than third side.
So, first, second and third side of the triangle is
So, its satisfy the triangle rule.
Therefore, Inequality is
Part 8.
Property of the triangles.
Sum of two side of triangles must be greater than third side.
So, first, second and third side of the triangle is
So, its satisfy the triangle rule.
Therefore, Inequality is
Answer:
17.03 meters
Step-by-step explanation:
The circumference of a circle:
where r is the radius and d is the diameter.
Given the diameter here, all you need to do is multiply it by pi:
Rounded to 2 decimal places, you get 17.03 meters.
Answer:
<em><u>y= -3x+3</u></em>
Step-by-step explanation:
We can set this problem up as an algebraic equation, which we can then solve to find our answer.
We start at -3. So we can start our equation with that:
However, this doesn't represent any change in temperature, just that we start at -3. To show change, we will use the variable , where stands for the number of hours. Each hour accounts for a change of -2.5 in degrees, meaning that we must multiply our by -2.5. We can now add this term into our equation:
We are trying to find when we will reach -18 degrees, so we will set our entire equation equal to -18 and solve:
It will take us 6 hours, or choice A.
