Janeesa lives 247.5 miles away from her grandmother, and the speed limit on that stretch of
highway is 55 miles per hour. Today, she only has 4 hours to get to her grandmother's birthday
lunch on time!
How much faster over the speed limit does Janeesa need to drive to make it on time? Round to the
tenths place if your answer isn't a whole number.
mph.
Answers
distance = rate x time
In this case, the distance is 247.5 miles, the time is 4 hours, and the rate is what we're trying to find. Rearranging the formula to solve for rate, we get:
rate = distance / time
Plugging in the values we know, we get:
rate = 247.5 / 4 = 61.875
So Janeesa needs to travel at an average speed of 61.875 miles per hour to make it to her grandmother's birthday lunch on time. Since the speed limit is 55 miles per hour, she would need to drive 6.875 miles per hour faster than the speed limit. Rounding to the tenths place, that's about 6.9 miles per hour over the speed limit. However, it's important to remember that speeding is dangerous and can result in serious accidents. It's always better to leave earlier and plan ahead to avoid the need to speed.
Janeesa needs to drive about 6.9 mph faster than the speed limit to make it on time.
What is the speed limit
To find out how fast Janeesa needs to drive to make it on time, one can use the formula:
distance = rate x time
In this case, the distance is 247.5 miles, the time is 4 hours, and the rate is what we're trying to find. Rearranging the formula to solve for rate, we get:
rate = distance / time
Plugging in the values we know, we get:
rate = 247.5 / 4 = 61.875
To know how much faster Janeesa needs to drive, one has to subtract the speed limit from the required speed:
Speed Difference = Required Speed - Speed Limit
= 61.875 mph - 55 mph
= 6.875 mph
Therefore, Janeesa needs to drive approximately 6.9 mph faster than the speed limit to make it on time.

We are given that;
Amount borrowed= $290,000
Time 25 years
Payment= $1, 530.73
Now,
To calculate the balance on the loan at the end of month 4, we can use the following formula2:
Balance = (Loan amount - Debt payment) * (1 + Interest rate / 12) - Debt payment
Where:
Loan amount is the original amount borrowed ($290,000)
Debt payment is the amount of principal paid in each monthly payment ($564.06 for the first month and $565.94 for the second month)
Interest rate is the annual interest rate divided by 100 (0.04)

The scale factor of figure STUV to figure WXYZ is 3:1. If ST = 39 mm and SV = 51 mm, what is the length of side WX?
Answers
The scale factor of figure STUV to figure WXYZ is 3:1. If ST = 39 mm and SV = 51 mm, the length of side WX is 13 mm.
If the scale factor of figure STUV to figure WXYZ is 3:1, it means that every length in figure STUV is three times longer than the corresponding length in figure WXYZ.
To find the length of side WX, we need to first identify the corresponding sides of the two figures. We know that ST is three times longer than W, and SV is three times longer than Y. So, we can set up the following proportion:
ST/WX = SV/YZ
Substituting the given values, we get:
39/WX = 51/YZ
We need to find the value of WX, so we can solve for it by cross-multiplying the proportion:
39 * YZ = 51 * WX
Since we don't know the value of YZ, we need to find it in terms of WX. We can use the scale factor of 3:1 to relate the lengths in the two figures:
ST = 3 * W
SV = 3 * Y
Substituting the first equation, we get:
W = ST/3 = 39/3 = 13 mm
Substituting the second equation, we get:
Y = SV/3 = 51/3 = 17 mm
Now we can substitute these values into the proportion:
39/WX = 51/17
Solving for WX, we get:
WX = (39 * 17) / 51 = 13 mm

Base twelve needs twelve digits, so we use t for ten and e for eleven and our usual ten digits. What base ten number does 1t5e twelve represent?
Answers
Therefore, 1t5e twelve represents the number 3239 in base ten.
what is system of equations?
A system of equations is a set of two or more equations with the same variables. The solution to a system of equations is a set of values for the variables that satisfy all the equations in the system simultaneously.
For example, consider the following system of two equations:
x + y = 5
2x - y = 3
This is a system of two equations with two variables, x and y. The solution to this system is the values of x and y that make both equations true at the same time. In this case, the solution is x = 2 and y = 3, because when we substitute these values into the equations.
In base twelve, the place values increase by a factor of twelve at each position, starting from the rightmost position. The rightmost position has a place value of 1, the next position to the left has a place value of 12, the next position to the left has a place value of 12^2 = 144, and so on.
To convert the number 1t5e in base twelve to base ten, we need to multiply each digit by its corresponding place value, and then add up the results:
1t5e (base twelve) = 1 * 12^3 + 10 * 12^2 + 5 * 12^1 + 11 * 12^0
= 1 * 1728 + 10 * 144 + 5 * 12 + 11 * 1
= 1728 + 1440 + 60 + 11
= 3239
Therefore, 1t5e twelve represents the number 3239 in base ten.

An urn contains 10 red balls, 20 yellow balls, and 60 orange balls. If you reach into the urn and select a single ball at random, what is the probability of selecting a orange ball?
Answers
Answer:
2/3 or 67%
Step-by-step explanation:
To find the exact probability for you to reach into the orange balls you'll have to do a data table on which you'll include how many orange balls are by the total amount of balls that are within the urn.
For example:
The urn contains:
* 10 red balls
* 20 yellow balls
* 60 orange balls
Total amount of balls that you have on the urn is 90, you'll get this result by doing a simple addition of the table of content.
Afterwards, we have to find the probability, so you will have to take the amount of orange balls (which is 60) and divide it by 90 (Which is the total amount of balls you have on the urn).
60/90
A quick tip for you to do this on a simplified manner is by dividing the numerator and the denominator by their greatest common divisor (Which in this case is 30) (30x2 = 60) (30x3 = 90)
60/90 = (60 divided 30) / (90 divided 30) = 2/3
To resolve this problem, we get that the probability of selecting an orange ball is 2/3 or approximately 0.67 which we'll simplify to 67%

Marcus and Tony work for Lombardo's Pipe and Concrete. Mr. Lombardo is preparing an estimate for a customer. He knows that Marcus lays a slab of concrete in 9 hours. Tony lays the same size slab in 3 hours. If both work on the job and the cost of labor is $48.00 per hour, decide what the labor estimate should be.
Answers
If both Tony and Marcus work on the job and the cost of labor is $48.00 per hour then labor estimate for the job is $576.00.
Marcus: 1 slab / 9 hours = 1/9 slab per hour
Tony: 1 slab / 3 hours = 1/3 slab per hour
The total amount of work they can do in one hour is the sum of their individual rates:
Marcus and Tony: 1/9 + 1/3 = 4/9 slab per hour
So together, Marcus and Tony can lay 4/9 of a slab per hour.
time = work / rate
time = 1 / (4/9) = 2.25 hours
total labor cost = hours worked x cost per hour
The total number of hours worked is the sum of the hours worked by Marcus and Tony:
total hours worked = 9 hours + 3 hours = 12 hours
The cost per hour is $48.00, so the labor estimate for the job is:
total labor cost = 12 hours x $48.00/hour
= $576.00
Therefore, the labor estimate for the job is $576.00.

a cable technician working fo the local cable company needs to lay down cable down through the neighborhood below. He is unsure how much cable cable he needs, though. Use the pythagorean theorem to help him find the length in feet of cable he needs to fufill his duty
Answers
Let's say the distance he needs to cover is 1000 feet and there is a height difference of 200 feet between the two points.
Using the Pythagorean theorem, we can find the length of cable he needs:
c² = a² + b²
where c is the length of the cable, a is the distance he needs to cover, and b is the height difference between the two points.
Plugging in the values we have:
c² = 1000² + 200²
c² = 1,040,000
c = √1,040,000
c ≈ 1,020.62
Therefore, the technician needs approximately 1,020.62 feet of cable to fulfill his duty.

z = invNorm(0.6) = 0.2533
Now we can use the formula z = (x - mu) / sigma to find the diameter x that corresponds to this z-score:
0.2533 = (x - 25.1) / 0.08
x - 25.1 = 0.020264
x = 25.120264
Therefore, the 60th percentile of the diameters is 25.120264 millimeters.
b. To find the 32nd percentile of the diameters, we need to find the diameter that separates the smallest 32% of the diameters from the largest 68%. We can use a standard normal distribution table to find the z-score that corresponds to the 32nd percentile:
z = invNorm(0.32) = -0.4472
Now we can use the formula z = (x - mu) / sigma to find the diameter x that corresponds to this z-score:
-0.4472 = (x - 25.1) / 0.08
x - 25.1 = -0.035776
x = 25.064224
Therefore, the 32nd percentile of the diameters is 25.064224 millimeters.
c. To find the diameter of the hole, we need to find the diameter that separates the smallest 1% of the diameters from the largest 99%. We can use a standard normal distribution table to find the z-score that corresponds to the 1st percentile:
z = invNorm(0.01) = -2.3263
Now we can use the formula z = (x - mu) / sigma to find the diameter x that corresponds to this z-score:
-2.3263 = (x - 25.1) / 0.08
x - 25.1 = -0.186104
x = 24.913896
Therefore, the diameter of the hole should be 24.913896 millimeters.

The exponent by which base b must be raised to get a positive real number an is the logarithm of a positive real number a with regard to base b, a positive actual number that is not exactly one.
What is a logarithm?A logarithm is the power to which a number must be raised in order to receive extra values. The simplest approach to express really large numbers is in this way. A number of important features of a logarithm demonstrate the fact that multiplication and division of logarithms can also be used to represent addition and subtraction logarithms.
The exponent by which base b must be raised to get a positive real number an is the logarithm of a positive real number a with regard to base b, a real number that is positive but not equal to one.
i.e., [tex]b^y=a[/tex] ⇔ [tex]log_b[/tex] a = y
In this case, "A" and "B" are two positive real numbers.
Y is an actual number.
Argument occurs inside the log as "a" by the name argument.
It is said that the base, or "b," is at the bottom of the log.
To put it another way, the logarithm provides a solution to the problem of "How many times is a number divided to get the other number?"
How numerous times must three be multiplied, for instance, to yield the number 27?
27 is the outcome of multiplying 3 times by 3.
Consequently, the logarithm is 3.
The logarithm form is written as follows:
[tex]log_3[/tex] (27) = 3 - equation 1
The base 3 logarithm of 27 is therefore 3.
It is also possible to write the above logarithm form as:
3x3x3 = 27
3³ = 27 - equation 2
Equations (1) and (2) are hence equivalent.

The volume of the given right cone is approximately 597.9 cubic units.
In this problem, we are going to find the volume of a right cone. A cone is a three-dimensional object that has a circular base and tapers to a point. The term "right" means that the axis of the cone is perpendicular to its base. The formula for the volume of a right cone is V = (1/3)πr²h, where V is the volume, r is the radius of the circular base, and h is the height of the cone.
Now, let's apply this formula to the given cone. We are given that the radius of the circular base is 16 and the height of the cone is 7. So, we can substitute these values into the formula to get:
V = (1/3)π(16)²(7) V = (1/3)π(256)(7) V = (1/3)(1,792π) V ≈ 597.9

Answers
Answer:
Approximately 15.7 ft
Step-by-step explanation:
We want to find the circumference of the circle
C = pi * diameter
C = pi *5
C = 5pi ft or approximately 15.7 ft
C = 2πr
where C is the circumference, π (pi) is a mathematical constant approximately equal to 3.14, and r is the radius of the circle.
We are given that the diameter of the roller is 5 feet. The radius of the roller is half of the diameter, which is:
r = d/2 = 5/2 = 2.5 feet
Substituting this value in the formula for the circumference, we get:
C = 2πr = 2π(2.5) = 5π
Therefore, when the roller has made one turn, it has traveled a distance equal to 5π feet (approximately 15.7 feet).

* So for 1 cup of granula mix, you need 3/4 / 4 = 3/12 teaspoon of cinnamon.
* For 12 cups of granula mix, you would need 12 * (3/12) = 3 teaspoons of cinnamon.
Therefore, for 12 cups of granola mix you would need 3 teaspoons of cinnamon.
