The relationship between what Alex typed and what Tasha typed can be represented by a simple equation.
Where: 'A' the number of words Alex typed in a minute and T is the number of words typed by Tasha in a minute.
Therefore Tasha typed
43.9 words in one minute.
Hope this helps!
For both part A and part B, the cross-section would be a square.
For part c, the reasons the shapes are the same is the 3-D figure of a cube has 6 faces that are all squares. Since every face is a square, you cannot cut a cross-section that is any shape but a square. Cross-sections in 3-D prisms can reflect the face they are nearest to, so with every face being identical on a cube, the cross sections are also identical.
I hope this helps! :)
This is actually pretty easy. Since we want lines, we can eliminate the bottom 2. The symbol for perpendicular is an upside down T so it is B
Answer:
Joe is 14.
Martha is 28.
Step-by-step explanation:
Use the variables and information from the question to make equations.
If Joe's age is half Martha's:
(1/2)m = j OR 2j = m
If their ages combined is 42:
m + j = 42
We can substitute the equation m=2j into equation m + j = 42, replacing "m".
m + j = 42 Substitute m for 2j
2j + j = 42 Combine like terms, terms with same varables
3j = 42 Divide both sides by 3 to isolate j
j = 14 Joe's age
Since j = 14, we can substitute it into equation m=2j to find "m".
m = 2j Substitute j for 14
m = 2(14) Simplify
m = 28 Martha's age
Therefore Joe is 14 and Martha is 28.
