Answer:
A. 176
Step-by-step explanation: First, to find the surface area to each triangle, you multiply the base times the height by 1/2. It is 28 for each triangle. Multiply that by 4, and you get 112. Then, the surface area of the square on bottom is 64. When added together, you get 176. No rounding needed. Hope it helped and is correct!
Answer:
Length = 45 m
Width = 185 m
Step-by-step explanation:
Given:
Perimeter of rectangular rug = 460 m
width of the rug is five meters more than 4 times the length
To find:
Width and length of rug = ?
Solution:
Let the length = 
m
As per given statement,
Width = 
m
Formula for perimeter of a rectangle = 
Width = m
Width = 
So, the answer is:
<em>Length = 45 m</em>
<em>Width = 185 m</em>
<em></em>
The answer is gonna be 415
Answer:
A number line going from 0 to 3. An open circle is at 2. Everything to the left of the circle is shaded.
Step-by-step explanation:
First, remember that when an endpoint is not in the solution set, we graph an open circle. While if the endpoint is in the solution set, we graph it with a closed circle.
For example, in:
x > 2
x = 2 is not a solution, then we will have an open circle at x = 2
While in the case of:
x ≥ 2
x = 2 is a possible solution, then we graph with a closed circle.
Ok, in this case we have:
t < 2
t is strictly smaller than 2, and t = 2 is not a solution.
Then:
we will have an open circle at 2, and we need to shade all the values to the left of 2 (the values smaller than 2)
The correct option is:
A number line going from 0 to 3. An open circle is at 2. Everything to the left of the circle is shaded.
Answer:
-45
Step-by-step explanation:
-50 + 2a represents the sum of the constant -50 and twice the value of the variable a.
If a = 2.5, then -50 + 2a has the value -50 + 2(2.5) = - 50 + 5 = -45.
