a rectangular garden with an area of 48 ft has a width equal to 1/3 its length. What is the measure of the diagonal of the garden? Express your answer as a decimal to the nearest hundredth.
Answers
Given the area of the rectangular garden:
\(A=48ft\)You know that its width is:
\(w=\frac{1}{3}l\)Where "l" is the length of the rectangular garden.
Let be "d" the length (in feet) of the diagonal of the garden.
You can draw the rectangle described in the exercise:
By definition, the area of a rectangle can be calculated using this formula:
\(A=lw\)Where "l" is the length and "w" is the width.
In this case, substituting the expression that corresponds to "w" and the area of the rectangular garden into the formula, you get this equation:
\(48=l(\frac{1}{3}l)\)Now you can solve for "l" in order to find its value:
\(\begin{gathered} 48=\frac{1}{3}l^2 \\ \\ (3)(48)=l^2 \\ \sqrt[]{144}=l \\ \\ l=12ft \end{gathered}\)By definitio

Chris can drive 41 miles for every 3 gallons of gas. At this
rate, how many gallons of gas will he need to travel to his
in-laws' house, 369 miles away?
Answers
Answer:
27 gallons
Step-by-step explanation:
If for every 41 miles, 3 gallons are needed. Using what we know, 369 ÷ 41 = 9. This means, to get 369 miles, we need to times the first amoiyng of gallons needed to drive 41 miles, which is 3, and times it by 9. (3×9=27) Therefore, 27 gallons of gas is needed.

below?
20/√5
Answers
The expression that can be used to completely rationalize the rational fraction is 20/√5 is 20/√5 * √5/√5 based on the given expression
What are rational expressions?Rational expressions are expressions that are represented by the quotient of two polynomials or radicals. This means that, a rational expression is represented by a fraction whose numerator and denominator are polynomials or radicals
How to rationalize the expression?The irrational expression is given as:
20/√5
To rationalize the irrational expression, we multiply the numerator and the denominator by √5
So, we have:
20/√5 * √5/√5

write 464000 in correct scientific notation
Answers
Answer:
The scientific notation is a method of writing very large or very small numbers in a more compact and easy to read format. It is expressed in the form of a x 10^n, where "a" is a number between 1 and 10, and "n" is an integer.
To write 464000 in correct scientific notation, we need to move the decimal point to the left until we get a number between 1 and 10. We count the number of places we moved the decimal point, and that will be the exponent of 10.
So, we can write 464000 as:
4.64 x 10^5
Therefore, the correct scientific notation of 464000 is 4.64 x 10^5.

Rebecca carries a balance on her credit card each month. Today is the first day of the new, 28-day billing cycle. The current balance is x and the APR is 24%. Rebecca is buying a friend an expensive gift that costs $1,400 that she plans to put on her credit card. This will be her only purchase this month, and she will be making this purchase on the last day
of the month.
Part A
If her finance charge will be $51, write and solve an equation to determine her current balance on her credit card. Show your work.
Part B How much in finance charges can she save by making the purchase on the last day of the billing cycle versus the first day of the billing cycle?
Answers
Part A: If her finance charge will be $51, an equation to determine Rebecca's current credit card balance is x = (51 - 1) ÷ 0.02.
Part B: Rebecca can save $27 in finance charges by making the purchase on the last day of the billing cycle instead on the first day.
What is an equation?An equation is a mathematical statement showing that two or more mathematical expressions share equality in value.
Equations are depicted using the equation symbol (=).
What is a finance charge?A finance charge includes the interest and other fees charged on credit cards.
The finance charge is usually based on a stated APR (annual percentage rate).
The billing cycle for the month = 28 days
Current beginning balance = x
Annual percentage rate (APR) = 24%
Monthly percentage rate (MPR) = 2% (24% ÷ 12)
Purchase on the last day = $1,400
Total finance charge for the month = $51
Finance charge for the last-day purchase = $1 ($1,400 x 2% x 1/28)
Finance charge for the beginning balance = $50 ($51 - $1)
The current beginning balance, x = $2,500 ($50 ÷ 2%)
Equation for current beginning balance, x = 51 - 1 ÷ 0.02
Total finance charge for the last-day purchase = $28 ($1,400 x 2%)
Savings in finance charge by purchasing ont the last day = $27 ($28 - $1)
Thus, Rebecca can save $27 in finance charge when she purchases the $1,400 gift for her friend on the laset day of the billing cycle instead of on the first day.

A report about how American college students manage their finances includes data from a survey of college students. Each person in a representative sample of 793 college students was asked if they had one or more credit cards and if so, whether they paid their balance in full each month. There were 500 who paid in full each month. For this sample of 500 students, the sample mean credit card balance was reported to be $825. The sample standard deviation of the credit card balances for these 500 students was not reported, but for purposes of this exercise, suppose that it was $195. Is there convincing evidence that college students who pay their credit card balance in full each month have a mean balance that is lower than $907, the value reported for all college students with credit cards?

a. Carry out a hypothesis test using& significance level of 0.01.
b. State the appropriate null and alternative hypotheses.

Answer:
Following are the responses to the given question:
Step-by-step explanation:

Using the sine ratio in the right triangle
sin49° = \(\frac{opposite}{hypotenuse}\) = \(\frac{FH}{FG}\) = \(\frac{FH}{8}\) ( multiply both sides by 8 )
8 × sin49° = FH , then
FH ≈ 6.0 ( to the nearest tenth )

sin = opposite/hypotenuse
opposite = sin * hypotenuse
sin (49) = 0,75471

Suppose you are driving. You notice that after driving for 3 hours, you are 165 miles from Seattle. You continue driving, and calculate that after driving 8 hours you are 415 miles from Seattle.
Answers
ANSWER:
50 miles per hour
450 miles
865 miles
STEP-BY-STEP EXPLANATION:
We can calculate the rate with the help of the points we have, just like this:
\(\begin{gathered} r=\frac{415-165}{8-3}=\frac{250}{5} \\ r=50\text{ miles per hour} \end{gathered}\)Therefore, the rate is 50 miles per hour
We know the rate, therefore, after 9 hours, the distance would be:
\(50\frac{miles}{hour}\cdot9hours=450miles\)Therefore, every 9 hours, a total distance of 450 miles is traveled.
We know that they are 415 miles from Seattle after 8 hours, so the total distance can be calculated as follows:
\(415miles+(17hours-8hours)\cdot50milesperhour=865miles\)Which means that after 17 hours, it is 865 miles away.

On one day, 4 chefs and 5 helpers earned $650.
On another day working the same number of hours
at the same rate of pay, 5 chefs and 6 helpers
earned $800.
How much does a chef earn each
day?
Answers
5c + 6h = 800 where c are chefs, h are helpers
Start by finding an expression for c
4c + 5h = 650
4c = 650 -5h
c = (650- 5h)/4
Then substitute that into the second equation and solve for a number value for h
5 (650-5h)/4 + 6h = 800
(3250-25h)/4 + 6h = 800
Multiply both sides by 4
3250-25h + 24h = 3200
-h = -50
h = 50
Take that 50 and substitute it into the expression we have for c to get a number value for c
C= 650-5(50)/4
C = 650-250/4
C = 400/4
C= 100
Check your first equations, substituting $50 for the helpers and $100 for the chefs.
4 (100) + 5(50) =
400 + 250 = 650
5(100) + 6(50) =
500 + 300 = 800
