Step-by-step explanation:
Jorge mows his 1/3 acre lawn in 5/6 hour. How many acres will he mow in an hour
Answer:
2/5 an acre
Step-by-step explanation:
We multiply the 5/6 hour by 6/5 to get 1 hour.
We then have to do this to the 1/3 and we get 6/15 or 2/5
Jorge mows 2/5 acres per hour. This is calculated by dividing the fraction of the acre mowed by the fraction of the hour taken. The result from the calculation shows that Jorge’s mowing rate is 2/5 acres per hour.
To find out how many acres Jorge will mow in an hour, we need to determine his mowing rate in acres per hour. We know that Jorge mows 1/3 acre in 5/6 hour. We can use the formula for rate:
Rate = Distance / Time
Here, the distance is 1/3 acre and the time is 5/6 hour. So, we can calculate his rate:
Rate = (1/3) / (5/6)
To divide fractions, we multiply the first fraction by the reciprocal of the second fraction:
Rate = (1/3) * (6/5) = 6/15 = 2/5
Therefore, Jorge mows 2/5 acres per hour.
You are making payments for a $1,475 loan that has a simple interest rate of 7.54% for 5 years.
What is the total amount you will owe? How much is each monthly payment?
Answer:
$2,031.08
Step-by-step explanation:
You want to calculate the interest on $1475 at 7.54% interest per year after 5 year(s).
The formula we'll use for this is the simple interest formula, or:
I=P x r x t
P is the principal amount, $1475.00.
r is the interest rate, 7.54% per year, or in decimal form, 7.54/100=0.0754.
t is the time involved, 5....year(s) time periods.
So, t is 5....year time periods.
To find the simple interest, we multiply 1475 × 0.0754 × 5 to get that:
The interest is: $556.08
Usually now, the interest is added onto the principal to figure some new amount after 5 year(s),
or 1475.00 + 556.08 = 2031.08. For example:
If you borrowed the $1475.00, you would now owe $2031.08
If you loaned someone $1475.00, you would now be due $2031.08
If owned something, like a $1475.00 bond, it would be worth $2031.08 now.

Final answer:
The expression −(1/4· 1/4· 1/4· 1/4) is written using exponents as −(1/4)⁴.
Explanation:
The expression −(1/4· 1/4· 1/4· 1/4) can be rewritten using exponents by recognizing that we are multiplying 1/4 by itself four times. Converting a repeated multiplication into exponential form means we use a base (which is 1/4 in this case) and an exponent (the number of times we multiply the base by itself). Thus, we write the expression as −(1/4)⁴. The negative sign just indicates that the result should be taken as the opposite (negative) value of (1/4)⁴.
Jayden has already jarred 1 liter of jam and will jar an additional 6 liters of jam every day. Write an equation that shows the relationship between the days d and the jam made j.
Write your answer as an equation with j first, followed by an equals sign
please help
Answer:
[tex]j=1+6d[/tex]
Step-by-step explanation:
Jayden jars jams at a rate of 6 liters per day which can be represented by the variable [tex]6d[/tex]. In other words, the amount of jam Jayden will have made in the end (j) is 6 liters multiplied by the number of days (d) he spent jarring jam.
However, Jayden has already jarred 1 liter of jam which has to be factored into the end total (j). To factor this liter in, you can add 1 (liter) to 6d.
On January 22nd , 2006, Kobe Bryant scored 81 points against the Toronto Raptors. Including three‐pointers, two‐pointers, and free‐throws he made 46 shots. He made three times as many two‐point shots as three‐point shots. How many free-throws did Kobe Bryant make?
Answer:
18
Step-by-step explanation:
x = the number of free throws
y = the number of 2 pointers
z = the number of 3 pointers
x + 2y + 3z = 81
x + y + z = 46
y = 3z
x = 18 free throws
y = 21 two pointers
z = 7 three pointers
Kobe Bryant made 18 free throws.

The sum of two numbers is 34. The smaller number is 14 less than the larger number. What are the numbers?
larger number:
Smaller number:
Answer:
larger number : 24
smaller number : 10
Step-by-step explanation:
Final answer:
To find the two numbers whose sum is 34 with one being 14 less than the other, equations were set up and solved. The larger number is 24, and the smaller number is 10.
Explanation:
The sum of two numbers is given as 34, and it is known that the smaller number is 14 less than the larger number. To find these numbers, we can set up a system of equations. Let's denote the larger number as L and the smaller number as S. According to the problem, we have two equations:
L + S = 34 (The sum of the larger and smaller number is 34)S = L - 14 (The smaller number is 14 less than the larger number)Substituting the second equation into the first one gives us:
L + (L - 14) = 34
Combining like terms, we get:
2L - 14 = 34
Adding 14 to both sides, we obtain:
2L = 48
Dividing both sides by 2 gives us the value of L:
L = 24
Now that we have the larger number, we can find the smaller number by subtracting 14 from L:
S = 24 - 14
S = 10
The numbers are 24 and 10, with 10 being the smaller number.
Find the amount of sap the maple syrup producer would have collected from each tree if the total amount if the total amount is (5gallons) was redistributed equally among trees
There are 10 crosses, which means that there are 10 trees in total. If we distribute 5 gallons among 10 trees, we give each tree
5/10=1/2=0.5 gallons
Answer:
Each tree will get 0.5 gallons of Syrup redistributed to it.
Step-by-step explanation:
According to the line graph shown in the picture there are 10 trees in total. We have 5 gallons of syrup that needs to be distributed equally among all ten trees. We can solve this by simply dividing the amount of syrup by the amount of trees that will be sharing the syrup.
5/10 = 0.5 gallons each
So each tree will get 0.5 gallons of Syrup redistributed to it.

When x = -1, f(x) = 0 because
(-1)^4 - 2(-1)^2 + 1 = 1 - 2 + 1 = 0.
Answer:
see explanation
Step-by-step explanation:
In order to determine the end behaviour, we only need to look at the term of highest degree, that is the leading term in standard form.
Given
f(x) = [tex]x^{4}[/tex] - 2x² + 1
So the term of highest degree is [tex]x^{4}[/tex]
Which is of even degree with positive coefficient
As a result the end behaviour is
As x approaches positive infinity, f(x) approaches positive infinity
As x approaches negative infinity, f(x) approaches positive infinity
----------------------------------------------------------------------------------------------
Substitute x = - 2 into f(x)
f(- 2) = [tex](-2)^{4}[/tex] - 2(- 2)² + 1 = 16 - 8 + 1 = 9 ≠ 0
Substitute x = - 1 into f(x)
f(- 1) = [tex](-1)^{4}[/tex] - 2(- 1)² + 1 = 1 - 2 + 1 = 0
Thus x = - 1 is a root of f(x) and (x + 1) is a factor of f(x)

which expression is a factor x^2-5x-6
Answer:
x^2 - 5x - 6 = (x - 2)(x - 3).
Step-by-step explanation:
f(x) = x^2 - 5x - 6
We need 2 numbers whose product is - 6 and whose sum is -5. They are -3 and -2:
The factors are x- 2 and x - 3.
Final answer:
The factors of the expression x²-5x-6 are (x-6)(x+1).
Explanation:
This question demands basic understanding of methods of factorization and finding solutions of an equation.
The method to find factors of an equation, ax² + bx + c = 0, find two numbers that multiply to get c and add to give b.
To find the factors of the expression x²-5x-6, we need to factorize it. We look for two numbers that multiply to give -6 and add to give -5. The numbers -6 and 1 fit these conditions.
So, x²-5x-6
=> x² - 6x + x- 6
=> x(x - 6) +1(x - 6)
=> (x - 6)(x + 1)
Therefore, the factors of the expression are (x-6)(x+1).

Let f (×)=2/5x^2-2. The function g (x) is a vertical stretch of f (x) by a factor of 2. What is the equation of g (x)?
g(x)=________
Answer:
g(x) = (4/5)x^2 - 2
Step-by-step explanation:
f(x) = (2/5)x^2 - 2 is the equation of a parabola with vertex at (0, -2).
Applying a vertical stretch of factor 2 to f(x) requires multiplying both the slope (2/5) and the y-intercept (-2) by 2:
g(x) = (2)(2/5)x^2 - 4, or
g(x) = (4/5)x^2 - 4.
