Answer:
Answers are below in bold.
Step-by-step explanation:
The first answer is correct. 1 m² = 10,000cm²
A=2(wl+hl+hw) To find the surface area of the package, use this equation
A=2(18*50+20*50+20*18) Multiply in the parentheses
A=2(900+1000+360) Add in the parentheses
A=2(2260) Multiply
A=4520
The package has a surface area of 4520 cm²
The area of the package is less than the area of the wrapping paper.
So, Dayson can completely cover the package with the wrapping paper.
5 1/3 - 3 2/6 simplify is 2.
The true statements about the equation y = 1.4x are
- (a) The equation represents a proportional relationship
- (b) The unit rate of y with respects to x is 1.4
- (d) A change of 2 units in x results in a change of 2.8 units in y
<h3>What are linear equations?</h3>
Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient
<h3>How to determine the true statements?</h3>
The equation is given as:
y = 1.4x
The above equation is a proportional linear equation.
This is so because proportional linear equations are represented as;
y = mx
Where m represents the unit rate of change
So, we have:
m = 1.4
Rewrite as:
m = 14/10
Simplify
m = 7/5
When x = 2, we have:
y = 1.4 * 2
Evaluate
y = 2.8
Hence, the true statements about the equation y = 1.4x are (a), (b) and (d)
