Write an expression to determine the length of the room in units of 3 feet.
Answer:
1/3LStep-by-step explanation:
The question with some background info added:
When measuring the dimensions of a room a carpenter uses a tape measure that only displays a number of feet, L, on the metal tape. (The carpenter's tape measure does not display inches) Write an expression to determine the length of the room in units of 3 feet. SolutionLet the length of the room be L feet measured by the carpenter
Then
L/3 = 1/3L would be measure of the length in units of 3 feetA pronghorn Antelope can run at speeds of about 59 miles per hour . what is that speed in feet per second, to the nearest whole number
Answer:
Step-by-step explanation:
To do this we need to first multiply by the number of feet in a mile to get:
311520 feet per hour
Then we divide by 3600 to get this into feet per second:
86.53333... feet per second
Now rounding this we get 87 feet per second.
what is the value of x in 3x+7y=27
Answer:
[tex]x = \frac{-7y}{3} +9[/tex]
Step-by-step explanation:
Note the equal sign, what you do to one side, you do to the other side. Do the opposite of PEMDAS. Isolate the variable, x.
PEMDAS is the order of operation, and =
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction
~
First, subtract 7y from both sides:
3x + 7y (-7y) = 27 (-7y)
3x = -7y + 27
Next, divide 3 from all terms on both sides:
(3x)/3 = (-7y + 27)/3
x = (-7y/3) + 9
[tex]x = \frac{-7y}{3} +9[/tex]
30 = −5(6n + 6) multi step equation show all steps pls
The solution to the equation is n = -2.
To solve the equation 30 = -5(6n + 6) step-by-step, follow these procedures:
Step 1: Distribute the -5 on the right side:
30 = -5 * 6n - 5 * 6
Step 2: Simplify the right side:
30 = -30n - 30
Step 3: Move constant term to one side:
30 + 30 = -30n
Step 4: Combine like terms:
60 = -30n
Step 5: Divide both sides by -30 to isolate 'n':
n = 60 / -30
Step 6: Simplify the right side:
n = -2
The solution to the equation is n = -2.

During harvesting season at Florida Blue Farms, hand pickers
collect about 200 pounds of blueberries per day with a 95%
pack-out rate. The blueberry harvester machine collects about
22,000 pounds of blueberries per day with a 90% pack-out rate.
The pack-out rate is the percentage of collected blueberries
that can be packaged to be sold, based on Florida Blue Farms'
quality standards.
Let h represent the number of days the hand pickers work and
m represent the number of days the harvester machine is used.
Which of the following algebraic expressions can be used to
estimate the amount of collected blueberries that are packed at
the Florida Blue Farms for fresh consumption this season?
A (0.95h+200)(0.90+22000)
B 0.95(200h)+0.90(22000m)
C 200.95h+22000.90m
D (200h+0.95)(22000m+0.90)
Step-by-step explanation:
its b..........
Bbbbb
The farm uses two harvesting tools for packages that needs to be sold. So, we have to consider the rates of both harvest tools and the number of harvest by both tools. The algebraic expression is: [tex]0.95(200h) + 0.90(22000m)[/tex]
Given that
[tex]h \to[/tex] days of hand pickers word
[tex]m \to[/tex] days harvester machine is used
[tex]n_h = 200[/tex] --- pounds of hand pickers
[tex]n_m = 22000[/tex] -- pounds of harvester
[tex]r_h = 95\%[/tex] -- pack out rate of hand pickers
[tex]r_m = 90\%[/tex] -- pack out rate of harvester
The expression to estimate the amount is calculated as:
[tex]Amount = r_h \times n_h + r_m \times n_m[/tex] --- i.e. pounds of hand picker * its pack out rate + pounds of harvester * its pack out rate
So, we have:
[tex]Amount = 95\% \times 200h + 90\% \times 22000m[/tex]
Express as decimal
[tex]Amount = 0.95 \times 200h + 0.90 \times 22000m[/tex]
Rewrite as:
[tex]Amount = 0.95(200h) + 0.90(22000m)[/tex]
Hence, option (b) is correct.

A Skier descended down a mountain at a rate of 14 feet per second.what was his total change in elevation after 8 seconds?
Answer:
1.75ft/s²Step-by-step explanation:
The total change in elevation of the skier is its acceleration. Acceleration is the change in velocity of a body with respect to time.
Acceleration = Velocity/Time
Given velocity of the skier = 14feet/sec
Time taken = 8secs
Acceleration of the skier = 14/8
Acceleration of the skier = 1.75ft/s²
Hence the total change in elevation after 8 seconds is 1.75ft/s²

9x-2+2x-8
11x-2-8
11x-10
Let me know if this helps :)
Answer:
11x - 10
Step-by-step explanation:
because there is a plus sign between the brackets, we just assume there are no brackets at all........so it will be:
9x - 2 + 2x - 8,,,,,,,,,bring the like terms together
9x + 2x - 2 - 8 = 11x -10.
the answer has a minus sign because when working out two negative numbers, we add them but still maintain the negative sign.
NOTE: If the sign between the brackets was a minus , the sign in the second expression would have changed from -8 to +8

A baby weighs 115 ounces. What is the baby's weight in pounds and ounces? *Plz explain your answer*
Answer:
7 pounds 3 ounces
Step-by-step explanation:
There are 16 ounces in a pound. In order to convert ounces to pounds, we need to see how many 16s fit into 115 (how many full pounds can be made with 115 ounces) and add the remainder as ounces. To do this we can do long division (which gives us 7 remainder 3), or we can divide 115 by 16 (=7.1875) and convert the decimal places to ounces by multiplying 0.1875 pounds (the remainder) by 16 (as there are 16 ounces in pound) which gives us 3 ounces.
So 115 ounces is equal to 7 pounds and 3 ounces.
Hope this helped!
The baby's weight is 7 pounds and 3 ounces.
To convert ounces to pounds, we need to divide the number of ounces by the conversion factor, which is 16. There are 16 ounces in 1 pound.
Let's denote the baby's weight in ounces as W oz, the weight in pounds as W lb, and the remaining ounces as Roz.
W oz = 115 ounces
W lb = ?
R oz = ?
First, we divide the total number of ounces by 16 to find the number of pounds:
W lb = W oz / 16
= 115/ 16
= 7.1875 pounds
So, the baby weighs 7 pounds.
To determine the remaining ounces, we multiply the decimal portion of the pounds (0.1875) by 16:
R oz = 0.1875 x 6
R oz= 3 ounce
So, the baby weighs an additional 3 ounces.
Therefore, the baby's weight is 7 pounds and 3 ounces.

the sum of three consecutive integers is 267. What is the largest integer?
Answer: 90
Step-by-step explanation:
We first need to find three consecutive numbers that adds up to 267. We know that the numbers will be somewhat close to 100 because the sum needs to be past 250.
Let's try 85,86,87.
85+86+87=258
258 is very close to 267. We know that we need to increase our numbers.
Let's try 88,89,90.
88+89+90=267
88,89, and 90 added together gives us 267. The question asks for the largest integer. In 88, 89, 90, 90 is the largest integer.

Use the difference quotient to calculate the average rate of change across the following intervals. Difference quotient of d(t): 3t^2 + 5th – 2
The interval 2 to 3:
The interval 2 to 2.5:
The interval 2 to 2.1:
Answer:
Ok, we have:
d(t) = 3*t^2 + 5*t - 2.
The first interval is:
(2, 3)
and remember that, for an interval (a,b), the difference quotient is:
D = (f(b) - f(a))/(b -a)
Then in this first interval we have:
[tex]d = \frac{d(3) - d(2)}{3-2} = \frac{3*3^2 + 5*3 - 2 - (3*2^2 + 5*2 - 2)}{1} = 20[/tex]
So the average rate of change in (2,3) is 20.
now, in (2, 2.5) we have:
[tex]d = \frac{d(2.5) - d(2)}{3-2} = \frac{3*2.5^2 + 5*2.5 - 2 - (3*2^2 + 5*2 - 2)}{1} = 9.25[/tex]
So here the rate of change is 9.25
And in the interval (2, 2.1) we have:
[tex]d = \frac{d(2.1) - d(2)}{3-2} = \frac{3*2.1^2 + 5*2.1 - 2 - (3*2^2 + 5*2 - 2)}{1} = 1.73[/tex]
So in this interval the rate of change is 1.73
Answer:
2 to 3 is 20
2 to 2.5 is 15
2 to 2.1 is 11
