Answer:
Perimeter= 12 feet Area= 6 feet (squared)
Step-by-step explanation:
Perimeter= Adding all the sides together, that means it is 3+4+5= 12 feet
Area= Hight times base divided by 2. Because hight times base is area of a rectangle, and a right triangle (and all other triangles) is half of it. Because it is a right triangle, its hight must be 3 or 4, and base also 3 or 4. But no the same number twice, so 3*4=12, 12/2=6 feet (squared).
I hope that helped! =)
Answer:
42% , 3/7 , 4/9 , 0.5
Step-by-step explanation:
4 / 9 = 0.4444444
3 / 7 = 0.4285714286
42 ÷ 100 = 0.42
The answer is B.
-9/3= -3, which means that each number is getting multiples by -3. Therefore, we can eliminate A and D. 27•-3=-81, so we can eliminate C. We are left with B, and we can check this by making sure that each number is correctly multiplied by -3.
Answer:
Positive
Step-by-step explanation:
Looking for - r/2
Having that negative in front is basically saying
-1 * r/2
Based on where r is it is negative.
-1 × -r thus making the answer going to be positive due to negative × negative = positive
Answer:
about $709 per month
Step-by-step explanation:
Okay, so in order to solve this question, we should follow this formula:
3,000 + 24x 
20,000
where 24 is the amount of time we have and x is the variable we are using as to show the unknown amount of money earned per month.
3,000 + 24x 20,000
-3,000 -3,000
24x 17,000
/24 /24
x approximately 709 dollars
so, we substitute x for 709
3,000 + 24(709) 20,000
3,000 + 17,016 20,000
20,016 20,000
which is true
Hope this helps :)
