Answer:
Hey mate!
Step-by-step explanation:
Lets take two places _ _
Now first position is filled in 4 ways (can use 2 3 7 9) that implies 4C1
then second position is filled in 3 ways since for first position we used a digit
and the condition is that not to repeat the digits, so it is done in 3C1 ways.
so the answer is 4*3 or (4C1*3C1)=12;

Answer:
1) 2^9 = 512
2) 2^(3t) = 2^6 for t=2
Step-by-step explanation:
1) An exponent is used to signify repeated multiplication. Here, the factor 2 is repeated 9 times, so the expression can be written using an exponent as ...
2^9
Using any of a variety of means, the value of this expression can be found to be ...
2^9 = 512
__
2) Assuming the bacteria reproduce by multiplying by some factor in a given time, we can divide the original expression into 3 parts:
(2×2×2) × (2×2×2) × (2×2×2)
If this represents the number after 3 hours, then the number after 2 hours is expected to be ...
(2×2×2) × (2×2×2) = 2^6
That is, there will be (2 h)/(3 h) = 2/3 times as many multiplications by a factor of 2. (2/3)(9) = 6 will be the exponent for the number after 2 hours.
-2x <-12
solve the inequality
Answer:
x > 6
Step-by-step explanation:
-2x < -12
divide by -2
switch signs because you're dividing by a negative number
-2x/-2 < -12/-2
x > 6
Hope this helps :)
Answer:
x > 6
Step-by-step explanation:
Solve -2x <-12 for x. Your answer must be a set of real numbers.
Divide both sides by -2. Note that if we here divide by a negative number, we must reverse the direction of the inequality symbol:
-2x < - 12
----- ------
-2 -2
This becomes x > 6, "the solution set"

The ratio of the interior angle measures of a triangle is 2:3:5. What are the angle measures?
In order from the smallest angle to the largest angle, the angle measures are __°, __°, and __°.
Show all steps.
Answer:
36:54:90
Step-by-step explanation:
you add all the parts together (2+3+5) which is 10. then you divide 180 by 10 because angles in triangle add up to 180. so 18 is one part
then you just times 18 by each part in the ratio
During a period of extreme cold, the average daily temperature dropped decreased by 112°F day. How many days did it take for the temperature to decrease by 9°F? Which equation would you use to find the solution?
A x + 112 = 9x + 112 = 9
B x − 112 =−9x − 112 =−9
C −112x = −9−112x = −9
D 112x = 9
It takes about 4 days for the temperature to decrease by 9°F.
An equation is an expression that shows the relationship between two or more variables or numbers.
Let x represent the number of days. Given that the temperature drop decreased by 1 1/2°F each day (- 1 1/2), for it to decrease by 9°F (-9):
-1 1/2 * x = -9
-1.5x = - 9
x = 4 days
It takes about 4 days for the temperature to decrease by 9°F.
What is not an example of kinetic energy?
Question 6 options:
Particles in motion, such as electricity
Elastic energy, such as a stretched archery bow.
Substances in motion, such as light, heat, and sound
Objects in motion
Answer: Please dont listen to the person above you the answer is C because a stretched bow is potential energy because the arrow is not moving but stretched holding potential energy for it to be released to its target thus making answer *C* correct
its honestly sad seing people hungry for points anyways enjoy your answer
Elastic energy, such as a stretched archery bow is not an example of kinetic energy.
What is Energy?Energy is the quantitative property that is transferred to a body or to a physical system, recognizable in the performance of work and in the form of heat and light.
Energy are of two types:
Potential Energy
Kinetic energy
potential energy, stored energy that depends upon the relative position of various parts of a system
Kinetic energy is the energy an object has because of its motion.
In the given options, Elastic energy, such as a stretched archery bow is not an example of the kinetic energy. because a stretched bow is potential energy because the arrow is not moving but stretched holding potential energy for it to be released to its target.
Hence, Elastic energy, such as a stretched archery bow is not an example of kinetic energy.

Solve six and two-sixths times one and one half.
six and two twelfths
eight and six twelfths
nine and six twelfths
ten and two twelfths
Step-by-step explanation:
First you need to change the mixed fractions into improper fraction which is 38/6 and the other fraction turns into 3/2 now since the question was about multiplying we multiply. So there are numbers that can be reduced like 3 divided by 6 and 38 divided by 2. So now that there are simpler nmbers that cannot be reduced more we multiply and we get 19/2 which if you wanted as a mixed fraction is 9 and 1/2.
Answer:
the answer is nine and six twelfths

A garden hose was left on in a yard and spilled 78 gallon every 23 minute. Find the average number of gallons spilled per minute.
Answer:
3.391 Gallons Per Minute
Step-by-step explanation:
78/23=3.391
Round 3.391 to 3.4
Answer:
≈3.39130434783 gallons per minute
Step-by-step explanation:
The information we get is a ratio, describing how many gallons of water will be wasted in 23 minutes, expressed as:
[tex]78 : 23[/tex] OR [tex]\frac{78}{23}[/tex]
We will use the fraction, the denominator is representing the time, which in this case, is 23 minutes. We want to have the denominator as 1 to find how much water will be spilled in one minute, to do this, we can divide both the numerator and denominator by 23:
[tex]\frac{78/23}{23/23} \\ =\frac{3.39130434783...}{1}[/tex]
And of course, if there's a need to round, go ahead.
And please do not waste water!

Answer:
The answer is B) a = -7/16
Step-by-step explanation:
3/4 + 4a/7 = 6a/7 + 7/8
By transposing, we get
=> 3/4 - 7/8 = 6a/7 - 4a/7
=> (by taking LCM) 6-7/8 = 6a-4a/7
=> -1/8 = 2a/7
=> -7 = 16a (by cross multiplication)
=> a = -7/16
Stephanie ran four laps around the school track in 7 minutes and 30 seconds. How many seconds per lap is that?
Answer:
112.5 seconds
Step-by-step explanation:
Stephanie ran four laps around the school track in 7 minutes and 30 seconds. How many seconds per lap is that?
You need to do convert 7 minutes in to seconds because you cannot do anything to this unless you convert it.
Remember
1 minute = 60 seconds.
So do 7 times 60.
7 × 60
Which is 420 seconds.
Now add the 30 seconds to that.
420 + 30.
Which is 450 seconds.
Now divided 450 by 4.
450 ÷ 4.
Which is 112.5 seconds per lap.

Answer:
285
Step-by-step explanation:
For the top section, we can portion out 20 x 8 = 160.
Next, directly in the middle is a 5 x 5 square = 25.
Finally, we have a right triangle with dimensions 10 x 20 so the area would be 10 x 20 / 2 = 100.
160 + 25 + 100 = 285.

Find the sale price and then add tax.
Pete wants to buy a new PlayStation 5 controller that is on sale. The controller cost $70 and is on sale for 40% off. If the sales tax is 10.1% how much will he pay for the controller?
Answer:
Your answer is $52.2 :)
Step-by-step explanation:
First, we need to find the sale, which is 40% of $70, we can do that by doing this equation: (40% x $70) / 100 = 28. Now we minus 28 from 70 in this equation: 70 - 28 = 42. Now we do tax, which is 10.1% of $42. We can do the same equation, but with the new information, so the new equation is ($42 x %10.1) / 100 which is 4.2042, and since we are talking money, we can make 4.2042, 4.2 (Rounded 0.042 down). Lastly, we add $4.2 (Tax) and $48 (Discounted price) to get $52.2. You're welcome :D

A scuba diver descends in the water at a rate of 2312 feet per minute for 2.6 minutes. He immediately changes course when he sees a large fish and ascends at a rate of 28 feet per minute for 2 minutes.
What is the scuba diver's position relative to sea level after the 4.6 minutes?
Enter your answer as a decimal in the box.
ft
2312 FPM for 2.6 minutes
2312 x 2.6 = 6011.2
28 FPM for 2 minutes
28 x 2 = 56
6011.2 descend
55 ascend
0-6011.2 = -6011.2
ans + 56 = -5955.2
:)
Answer:
Descends: 2,312 x 2.6 = - 6,011 (when rounding otherwise known as - 6,011.2, this number is negative because he is descending)
Ascends: 28 x 2 = 56
- 6,011 + 56 = -5,955 (in 4.6 minutes)
