Answer:
#13: 2.23×10⁻³ kg/cm³
#14: 10.23 ft²
Step-by-step explanation:
Good on you for thinking something wasn't right! Those conversions they gave you are correct, but the length conversions just aren't in the correct dimensions. In #13 you need cm² and in #14 you need ft³. To do this, you simply square or cube both sides of the conversions (because what you do to one side must be done to the other). Then you'll end up with conversions for two or three dimensional measurements. I have an attachment that shows my work, but I'll put an example here as well.
If 1in = 2.54 cm, then:
- (1 in)² = (2.54 cm)²
- 1² in² = 2.54² cm²
- 1 in² = 6.45 cm²
You can do this with any other conversion as well, so go wild with it!
Answer:
80×t=d
Step-by-step explanation:
t means time so if the train travels 2 hours
80×2=160miles
is a growth
Answer:
Solving for y gives:
Step-by-step explanation:
Linear equations are the equations that are degree one equations. When it is asked to solve an equation for a specific variable that means that the specified variable has to be isolated on one side of the equation i.e. in the given question solving for y means isolating y on one side of the equation.
Given equation is:
Multiplication property of equality(Multiplying both sides by q)
Division property of equality(Dividing both sides by 3)
Hence,
Solving for y gives:
Answer:
If ANY horizontal line intersects your original function in ONLY ONE location, your function will be a one-to-one function and its inverse will also be a function. The function y = 2x + 1, shown at the right, IS a one-to-one function and its inverse will also be a function.

Answer:
Area of shape B = 312.5 cm²
Step-by-step explanation:
Ratio of Area of A : Area of B = 12² : 15²
Given that area of A is 200 cm², let the area of shape B = x
Therefore:
200:x = 12²:15²
200/x = 144/225
Cross multiply
144x = 200*225
144x = 45,000
x = 45,000/144
x = 312.5 cm²
Area of shape B = 312.5 cm²
