Answer:
1. 151.29 in.²
2. 413 km²
3. 75 cm²
Step-by-step explanation:
1. 12.3 in. × 12.3 in. = 151.29 in.²
2. 17.5 km × 23.6 km = 413 km²
<u>The third is a parallelogram. To find the area of a parallelogram you multiply the base and height.</u>
3. 15 cm × 5 cm = 75 cm²

These images are about multiplication and the decimal numbers in the problems have been converted to fractions.
Answer:
I believe the answer is 34 cm (I may be wrong but I'm 98% that my answer is correct)
Step-by-step explanation:
(excuse my handwriting on the ss its hard to write on a computer lol)
hope this helps :)
Answer:
Step-by-step explanation:
400*60% can be rewriten as 400×0.6 which is 240, so a is false.
the same steps can be repeated for b and c
b) 200*0.6=120, therefore is false
c) 120*0.6=72, therefore is false
2)
Now we check the answer by using the same steps in problems a,b,c
3)
and finally
Answer:
A=56
Step-by-step explanation:
A= 8*14/2 /56
The only option that can be classified as a mathematical function is 2y=-12.
<h3>What is a function?</h3>
This refers to a mathematical expression that shows how a variable changes based on another variable, usually represented with y.
<h3>What mathematical expression is a function?</h3>
The only function is 2y=-12. Based on this reasons:
- Values will change depending on the value of y, which shows a relationship between two variables or a function.
- The changing value is represented by y.
- It is not an equality as it occurs in x= 13 or 2x-4x=7.
