Answer:
176 seconds
Step-by-step explanation:
By using regression line calculator,
Equation of the line of best fit will be,
T = -12.55x + 276.52
Here , T = time taken to cover one lap
x = Age
If the age of Marsha's son is 8 years then expected time taken by her son to cover one lap will be,
T = -12.55(8) + 276.52
T = -100.4 + 276.52
T = 176.12 seconds
Therefore, approximate time taken by Marta's son will be 176 seconds.
Answer:
5
Step-by-step explanation:
We know that Karen divided her garden into equal parts of which she intend to plant corn in ⁸/20 of it.
This implies that she divide the garden was divided into 20 parts.
To determine the fewer number of parts she can divide her garden into, simply ⁸/20.
Thus:
8/20 = (2*4)/(5*4)
= ²/5 (4 cancels out 4)
Therefore, this implies that the least number of parts she can divide her garden into is 5.
To solve these you have to follow the orders of operation(BEDMAS), which means brackets, exponents, division, multiplication, addition, subtraction all in that order.
A) This is false. 7x6+4=46 and does not equal 7x10 or 70.
B) This is false as well. The answer haste be 19 and 16-(4+7) does not equal 19. You add up what is in the brackets first and then subtract.
This means that C and D have to be true.
C) 10+(6/3)=12
10+2=12 True
D) 2+5x7=37
2+35=37
Also true
Answer:
$267.50
Step-by-step explanation:
This is the answer for 18.25 each and 2.50 each
If you mean 10 pizza for 18.25 combined and 20 drink for 2.50 combined then $55.75
Answer:
The answer to your question is the letter A
Step-by-step explanation:
Following the description, I understand that the input is "t", then,
A) This is the right answer because the equation is exactly what describes the sentence.
B) This choice is incorrect because in the second term it is not necessary to square t.
C) This choice is incorrect because both terms are square and that is not in the description.
D) This choice is wrong because the second term is subtracted and it must be added to the first term.
