A special machine is used at a construction site to dig holes. A hole is dug to a depth of 4.75 feet when the machine hits rock. The progress slows to 3/5 feet per hour of digging. The depth of the hole must be at least 12 1/2 feet by the end of the day to stay on schedule. What is the minimum amount of time the machine must continue at its present rate to complete the hole on schedule? Select from the drop-down menus to correctly complete the statement.
Answer: 12 h ; 45 m
Step-by-step explanation:
*Important: From what I can see in this image, this appears to be a test. If this is the case, please do not cheat. In any case, here is the explanation.
What we know:
Progress has been made to 4.75Rate of digging is 3/5 mphDepth must be at least 12 1/2We need to find the minimum amount of time the machine worksHow to solve:
By setting up an algebraic equation, we can solve this.
Process:
Set up equation 4.75 + 3/5x = 12 1/2Convert 19/4 + 3/5x = 12 1/295/20 + 12/20x = 250/20
Subtract -95/20 -95/2012/20x= 155/20
Isolate x via division /(12/20) /(12/20)+Simplifyx= 12 11/20
Convert 12 h 33 mSolution: 12 ; 45
The minimum amount of time taken by the machine will be 12 hours and 55 minutes.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
An exceptional machine is utilized at a building site to dig openings. An opening is dug to a profundity of 4.75 feet when the machine hits the rock. The advancement eases back to 3/5 feet each hour of digging. The profundity of the opening should be no less than 12 ¹/₂ feet before the day's over to remain on time.
Convert the mixed fraction number into a decimal number.
12 ¹/₂ feet = 12.5 feet
Let 'x' be the time. Then the equation is given as,
(3/5)x = 12.5 - 4.75
Simplify the equation, then we have
(3/5)x = 12.5 - 4.75
(3/5)x = 7.75
x = 12.9167
x = 12 + 0.9167 x 60
x = 12 hours and 55 minutes
The base measure of time taken by the machine will be 12 hours and 55 minutes.

which does not represent two equivalent expressions 51 MAFS.6.EE.1.1 Which does not represent two equivalent expressions?
A.) 33=3·3·3
B.) 43=4·3
C.) 64=6·6·6·6
D.) 52=5·5
Answer: B
Explanation: 4 times 3 is equivalent to 12 and the question was asking for exponents. A has 3 multiplied by itself 3 times so that is correct. C has 6 multiplying itself 4 times so that would be correct. D has 5 Multiplying itself 2 times so that would be correct. The only one that does not represent equivalency would be B.

Answer:
i = ($650)(0.08)(1) = $52
Step-by-step explanation:
The formula for simple interest is i = prt. Here p = $650, r = 0.08 and t = 1 (year). Then the simple interest Deanna paid for this one year loan was

Answer:
The answer is C
Step-by-step explanation:
2 2/3 + 3 1/2
first, add the whole numbers
(2+3)+( 2/3+1/2)
=5 and then you multiply each fraction by the other denominators
2/3 x 2 and 1/2 x 3
=5 4/6 3/6
Now add each fraction because it is the same denominator
4+3=7 so it is 7/6 now to make it a mixed fraction
7/6=1 1/6
5 +1=6
6+1/6 = 6 1/6

Solve the equation for all values of x by completing the square.
x^2 + 6x – 27 = 0
Answer:
Solution
=3
=−9
x=3
x=−9
x=3x=−9
Step-by-step explanation:
Boom
Answer:
x=-9 and 3
Step-by-step explanation:
FOIL method
x^2+6x-27=0
Find the common numbers that multiply to 27 that will also equal 6.
(27x6) or (9x3)
the 6 is positive while 27 is negative so you need to use a + and - in the parenthesis.
then FOIL them
(x+9)(x-3)
FIRST: x*x=x^2
OUTSIDE: x*-3=-3x
INNER: 9*x=9x
LAST: +9*-3=-27
x^2(-3x9x)-27
x^2+6x-27
now that the equation matches you solve for x.
(x+9)=0 x=-9
(x-3)=0 x=3

Meg is a veterinarian. She found that 5 or, 50% of the dogs she saw this week were boxers. Steve is also a veterinarian. He found that 50% out of the 2 dogs he saw this week were boxers. Does each person need to find the part, the whole, or the percent?
Question content area bottom
Part 1
Meg needs to find the

whole.
Part 2
Steve needs to find the
▼
percent.
part.
whole.
Answer:
a. Meg needs to find the part
b. Steve needs to find the percent.
Step-by-step explanation:
A. Does Meg need to find the part, the whole, or the percent.
Meg already knows the whole and the percent.
The whole is the entire number of dogs seen: 16 dogs.
The percent is 50%.
Hence, she needs to find the part: this is how many (what part) of the 16 dogs she saw were boxers.
And she can do with a simple operation:
Part = whole × percent = 16 × 50% = 8. This is 8 dogs of 16 were boxers.
B. Does Steve need to find the part, the whole, or the percent.
He already knows the part (7 of the 35 dogs were boxers) and the whole (35 dogs).
Then he needs to find the percent, which he can do using the next operation:
Percent = (part / whole) × 100 = (7/35)×100 = 20%
Step-by-step explanation:
Part 1:
Meg needs to find the whole as 50% of the dogs = 5 therefore 100% equals 10 dogs.
Part 2:
Steve saw 50% out of two dogs meaning that he only saw 1 dog that is a boxer.
Of the students in your class, 12% are left-handed. What fraction of the students are left-handed? Are there more right-handed or left-handed students? Explain. Write your answers in simplest form.
what is the fraction for the right handed people
Answer:
Step-by-step explanation:
12% is equivalent to 12/100. This reduces to 3/25. Thus, 3/25ths of the students are left-handed. The corresponding fraction for the right handed people is (25-3)/25, or 22/25ths. There are more right-handed people (22/25ths) versus left-handed people.
