Answer:
I'm pretty sure it's both, but I can see this is a summative exam/test so I'm really sorry if it's wrong.
Answer:
p < 0
Step-by-step explanation:
Given
- 3(p - 7) > 21
Divide both sides by - 3, reversing the symbol as a result of dividing by a negative quantity.
p - 7 < - 7 ( add 7 to both sides )
p < 0
Answer:
29 cans
Step-by-step explanation:
To solve this problem we must use Heron's formula; A = 
S = 1/2 the perimeter of the given triangle
a, b, c = the measurements of the three given sides
The first step to solving this question is first finding the perimeter.
P = 65m + 74m + 67m
P = 206m
Now that we have our perimeter, we must divide P by 2 to get S.
S = 206/2
S = 103
Now we plug our numbers into Heron's formula.
A = 
A = 
A = 
A = 
A = 
Find the square root of this number.
A ≈ 2021.43909134... m²
If a can of paint covers 70 square meters, then you will need to figure out how many cans you need. This can be done by dividing the overall area of the triangle by the area that a single can of paint can cover.
= 28.8777013049...
We know we can't buy 28.87... of a can (people simply do not sell parts of cans or half-full containers... unless its a bag of lays chips and their 80% air nonsense...) so we must round up to the nearest whole number.
28.87... = 29
Thus we finally have our answer: 29 cans of paint!
Answer:
See below.
Step-by-step explanation:
To find the amount in each section, divide the number of yards by the number of sections.
4/7 is the 4/7 yards per 1 section.
4/7 = 0.57 yards per 1 section.
etc.
Choose the option which DOES not represent these values.
