Answer:
choice 1
Step-by-step explanation:
A= 250 m²
Each triangle gets:
250/4= 62.5 m²
l=12 m, h= 10.4 m ⇒ A= 1/2*12*10.4 m²= 62.4 m² is the correct option, the rest give greater area
Answer:
860 degrees
Step-by-step explanation:
-210+210=0
0+650=650
650+210=860
Answer:
<h3>y≤9</h3>
Step-by-step explanation:
Make 2 eqn, let a be apples and o be oranges:
1. 5a + 4o = 10
2. 5a + 5o = 11
set up an elimination:
1. minus 2.
5a + 4o = 10
- 5a + 5o = 11
____________
o = 1
sub “o” into one of the eqn
5a + 5(1) = 11
5a = 11-5
5a = 6
a = 6/5
a = 1.2
therefore, an orange costs $1.00 and an apple costs $1.20
