Step-by-step explanation:
Tom has a part-time job. On Wednesday, Tom earned $20.50, and on
Thursday he earned $36.21. On Friday, Tom earned twice as much as he
did on Wednesday. How much did Tom earn altogether for the three days?
Answer:
97.71
Step-by-step explanation:
$20.50 (Wednesday) + $36.21 (Thursday) = $56.71 Since Tom is getting twice as much he did on Wednesday ($20.50), we'll be doing this: $20.50 x 2 (which equals 41 or $41.00) and add it to $56.71
$56.71 + $41.00 = $97.71 So, this means that Tom earned $97.71 altogether for three days

Find the area of the figure to the nearest thousandth.
Answer:
236.625 [tex]ft^{2}[/tex]
Step-by-step explanation:
In this question you need to figure out the area of the circle and the rectangle separating them. You would use this equation:
[tex]A=\pi 7.5^{2} +(4*15)[/tex]
Multiply everything in the parentheses to get the equation:
[tex]A=\pi 7.5^{2} +60[/tex]
Then square 7.5:
[tex]A= \pi 56.25+60[/tex]
Then multiply 56.25 by pi:
[tex]A=176.625+60[/tex]
Add the last two terms together to get the area of the figure which is :
[tex]A=236.625[/tex]

Answer:
50 dog walks in 10 hours (1 month)
Step-by-step explanation:
If Darius made 10 dog walks in 2 hours, then in one month, it took Darius 10 hours to make 50 dog walks.
Using the first formula, 2 hours ÷ 1/5 = 10, then
10 hours (in one month) ÷ 1/5 = 50 dog walks.
Hope this helps!
In problem #1, rewrite the problem using the reciprocal (the inverse) of 1/5 to 5/1 and change the division sign to multiplication. Do this for both equations.
Problem 1.) Write 2 ÷ 1/5 = 2 x 5/1 = 10.
Problem 2.) 10 ÷ 1/5 = 10 x 5/1 =50.
Problem 3.) Just explain that in one month, it took Darius 10 hours to walk 50 dog walks using the formula from problem 2 above. Good Luck!

Which solid figure could be formed from the net shown?
O rectangular prism
O triangular pyramid
cube
O square pyramid
Answer:
square pyramid
Step-by-step explanation:
It's definitely not rectangular prism because they have faces all with 4 sides, 4 of these faces only have 3 sides. I'm not sure what you mean by triangular pyramid cube. I call this shape a square - based pyramid which has a square base and 4 triangles that join to a point making a pyramid and square pyramid seems like it's just a different name for the same thing.
