Answer:
B) 44
Step-by-step explanation:
Let's start with the triangles. Normally, when dealing with triangles, you would use the formula (B*H*1/2), but since there's two identical triangles, we can just do (B*H) and get the area for both:
2.5*5.5=<u>13.75</u>
Then to solve for the square, it is also (B*H):
5.5*5.5=<u>30.25</u>
At this point, to solve for the total area, you just add the areas together:
13.75+30.25=<u>44</u>

Answer:
C is the correct answer due to two-step inequality process
Step-by-step explanation:
Your inequality is: 5a + 18 < -27
First, you must remember that the < or > shall not be shaded in.
You could automatically eliminate answer A.
Now you need to do two-step inequalities which is the same thing as two-step equations but with an inequality sign.
5a + 18 < -27
5a < -27-18
5a < -45
**Now, here's something important: If you are multiplying with negatives while dealing with inequalities you must switch the sign to its opposite.
-9 > a
You need to find a number line that has numbers less than -9. It could be -10, -11, -12, -122, etc.
C is the correct answer.
Answer:
1. 10 6/7 2. 8/15
Step-by-step explanation:
1. 6 1/42 + 4 5/6
- First, let's combine the whole numbers. 6 + 4 = 10
- Now we are left with 1/42 + 5/6.
- To add or subtract, the dominators need to be the same. We need to find the least common multiple which here is 42.
1/42 + 5/6(7)
1/42 + 35/42
= 36/42
= 6/7
- All we have to do is combine both numbers.
10 6/7
2. 13/15 - 1/3(5)
13/15 - 5/15
8/15
Solve the equation 1/30 + 1/45 = 1/x
where x is the required time
multiply thru by 90x:-
3x + 2x = 90
x = 90 / 5 = 18
answer 18 minutes
