The side lengths of the rectangle are reduced by a scale factor of 1/4. (The side lengths are 16 and 36in) What is the area of the new rectangle?
Answer:
36 i think
Step-by-step explanation:
16 divided by 4 is 4
36 divided by 4 is 9
4*9=36
Answer:
324 square inches
Step-by-step explanation:
1/4 of 16 = 4
16-4 = 12
1/4 of 36 = 9
36-9 = 27
A= l*w
A= 27 x 12
A= 324 square inches
The function f(x) = In(x) has a domain of all real numbers greater than zero and a range of all real numbers. The
inverse of this function is f-?(x) = ell. Which conclusion can be drawn by comparing the two functions?
The domain of f(x) is all real numbers and the range is all real numbers.
The domain of f(x) is all real numbers greater than 0 and the range is all real numbers.
The domain of f-1(x) is all real numbers and the range is all real numbers greater than 0.
The domain off-1(x) is all real numbers greater than 0 and the range is all real numbers greater than 0.
Answer: The domain of f-1(x) is all real numbers and the range is all real numbers greater than 0.
Step-by-step explanation:
The inverse function of f(x) = ln(x) is:
f-1(x) = exp(x).
And as:
The domain of f(x) is: x ∈ R, x > 0.
The range of f(x) is: x ∈ R
Then for the inverse, we should have the opposite:
The domain of f-1(x) is: x ∈ R (the exponential function does not have any problems like the logarithm, so you can actually input any real value).
The domain is: x ∈ R, x > 0.l
Because, for example:
e^0 = 1
e^-1 = 1/e > 0.
e^-n = 1/e^n > 0.
e^x is always positive, then the range is the set of all real numbers large than zero.
Answer:
The answer is C.

Help please. I'll give the Brainliest.
Answer:
Options 1,2,3 are correct statements
The first values in an ordered pair ( the coordinates) are the domain : ( -3,-2,-1,0,1)
The second values are the range : (-1,1,2,3,4,5)
One input should have only one output for a function.
But -1 input has 2 outputs: -1 and 3.
Thus, it is a relation and not a function.

Name the additive inverse of 5 + I
Answer:
so
Step-by-step explanation:
For example, the additive inverse of the positive number 5 is -5. ... This means that the additive inverse of a negative number is positive. For instance, if x equals -12, then its additive inverse is y = 12.
The additive inverse is (-5) + (-1)
what is additive Inverse?To get a result equal to 0, add the original number and the additive inverse by simply changing the sign of the integer. On the basis of negation of the original number, the characteristics of additive inverse are listed below. For instance, if x is the starting number, then -x is x's additive inverse.
Given:
5 + I
As, the additive inverse is the opposite sign of the given number.
For example, if the number is -6 and we have to find its additive inverse.
So, the additive inverse will be 6.
So, the additive inverse is (-5) + (-1)

Karen made $85 for 5 hours of work. At the same rate, how much would she make for 8 hours
Answer:
The correct answer would be $136
Step-by-step explanation:
If Karen made $85 in 5 hours and you want to figure out how much she would make in 8 hours, then you would first need to know how much she makes in 1 hour. Do to that, you would divide from 85 by 5, which would then give you 17. So that tells you how much Karen makes in 1 hour, now to find out how much she makes in 8 hours, all you have to do is multiply 17 and 8. Therefore, the answer to your question is Karen would make $136 in 8 hours.

The Mulder Farm has 600 acres of land allotted for raising corn and wheat. The cost to cultivate corn is $40 per acre. The cost to cultivate wheat is $25 per acre. The Mulders have $18,000 available to cultivate these crops. How many acres each crop should the Mulders plant
Answer: Corn = 200 acres
Wheat= 400 acres
Step-by-step explanation:
Let the number of acres of corn = c
Let the number of acres of wheat = w
The Mulder Farm has 600 acres of land allotted for raising corn and wheat. This will be:
c + w = 600
c = 600 - w
Cultivation cost equals:
= 40c + 25w = 18000
Since c = 600 - w, we slot it into the equation
40c + 25w = 18000
40(600 - w) + 25w = 18000
24000 - 40w + 25w = 18000
Collect like terms
24000 - 18000 = 40w - 25w
6000 = 15w
w = 6000/15
w= 400
400 acres of wheat will be planted
Since c + w = 600
c = 600 - 400
c = 200
200 acres of corn should be planted

Anna is really involved in after school activities and is a part of the Drama club, as well as the Junior Optimist club. Every three days, there is a Drama club meeting, and every 8th day, she has Junior Optimist club meeting. Today she is scheduled to attend both meetings. How many days will it be until she will have both meetings on the same day again?
Answer:
The next time she will have both meetings on the same day again is 24 days time
Step-by-step explanation:
The given information are;
The frequency of the Junior Optimist club meeting = Every 3 days
The frequency of the Drama club meeting = Every 8th day
The club meeting Anna will attend today = Both meetings
The next time she will have both meetings on the same day again is given as follows;
The next time she will have both meetings on the same day again = The number of days the complete cycles of both meetings will coincide = The product of the cycles of both meetings
The next time she will have both meetings on the same day again = 8 × 3 = 24 days
The next time she will have both meetings on the same day again = 24 days time.

Pete is having a cup of black coffee with breakfast. The glass weighs 100g and holds 100mL, so he says that the drink (the cup and coffee together) weighs 200g. Explain why Pete is mistaken
Answer:
The units g and mL measure different quantities.
Step-by-step explanation:
Pete knows the glass weighs 100g, so this is the weight of the cup.
It holds 100 mL, however, mL measures volume, not weight.
Pete is wrong about saying that the cup and coffee together weigh 200 g, because you cannot add two values together that have different units.
In this example, you cannot add together the weight of the cup and volume of the coffee, in order to get the total weight. You would have to find the weight of the coffee, then add that to the cup's weight.
So, Pete is wrong because you cannot add 2 values together that have different units.
Different quantities are measured by the units g and mL.
What is unit conversion?Multiplication or division by a numerical factor, selection of the correct number of significant figures, and unit conversion are all steps in a multi-step procedure.
Pete knows the glass weighs 100g, so this is the weight of the cup. It holds 100 mL, however, mL measures volume, not weight. Pete is mistaken when he claims that the coffee and cup combined weigh 200 g since you cannot add two values with different units of measurement.
In this case, you cannot calculate the entire weight by adding the weight of the cup and the volume of the coffee. You would need to determine the weight of the coffee and then increase it by the weight of the cup.
Therefore, Pete is wrong because you cannot add 2 values together that have different units.

Jose's batting average is 0.250 after 160 times at bat, which means he made a hit 40 of the times he was at bat. He wants to
improve his batting average to 0.333. If he makes a hit the next x times at bat, which equation can be used to calculate the number
of hits needed to obtain this improved batting average?
O A. 2+40
160
.333
Answer:
Step-by-step explanation:
Given that:
Batting average = 0.25 after 160 times at bat;
Batting Average = Number of hits / number of times at bat
0.25 = number of hits / 160
Number of hits = 0.25 * 160 = 40
He want batting average to improve to 0.333 ; if he makes hit the next x times at bat ; number of hits is needed to improve batting average
Hence,
New average = number of hits / number of times at bat
0.333 = (number of hits + x) / (160 + x)
0.333 = (40 + x) / (160 + x)

8 taps can fill a tank in 27 min with the same rate of flow. If 3 taps go out of order how long will the remaining taps take to fill the tank
Answer:
pls 5 star
Step-by-step explanation:
8 taps can fill a tank in 27 minutes.
So,
1 tap can fill the same tank in time = 27 × 8 = 218 minutes
Therefore, 6 remaining taps can fill the same tank = 216/6
= 36 minutes
The remaining 6 taps will take 36 minutes to fill the same tank.
