Answer:
A = about 62.82
Step-by-step explanation:
A=lw+l(w/2)2+h^2+w(l/2)2+h^2=4·4+4·(4/2)^2+5.5^2+4·(4/2)^2+5.5^2≈62.82
Answer:
The answer is 40
Step-by-step explanation:
55-15=40
(12 2/3)*(3 1/4) = 41 1/6 . . . . . according to my calculator
_____
You are usually taught to multiply the improper fractions and simplify the result.
.. (38/3)*(13/4) = (38/4)*(13/3)
.. = (19/2)*(13/3)
.. = (19*13)/6
.. = 247/6
.. = 41 1/6
You can also multiply the parts.
.. (12 2/3)*(3 1/4) = 12*3 + 12*(1/4) +(2/3)*3 +(2/3)*(1/4)
.. = 36 +3 +2 +1/6
.. = 41 1/6
Answer:
(a). $20,000
(b). The estimate will be lower than the actual amount.
Step-by-step explanation:
We have been given that Michael saves $423 dollars a month for college.
(a). We know that 1 year equals 12 months.
4 years = 4*12 months = 48 months.
Since we are asked to find the estimated amount of money Michael will save in 4 years, so we will estimate both quantities as:
Therefore, Michael will save approximately $20,000 in 4 years.
(b).
The estimate will be lower than the actual amount as we rounded $423 down $23 to nearest hundred that is $400 and rounded 48 up 2 to nearest ten that is 40.
Therefore, the estimate will be lower than the actual amount.
Answer: 360.73
Step-by-step explanation:
When you come across any question that says [a of b] is just saying a × b.
5.5% of x=5.5% × x
-----------------------------------------------------------------
Given
5.5% of x=19.84
Converted into numerical expression
5.5% × x=19.84
Divide both sides by 5.5% (0.055)
x=19.84 ÷ 5.5%
simplify
x=360.73 (rounded)
