Answer:
B. 36
Step-by-step explanation:
The pattern is multiplying by 3. You can figure this out by dividing 12 by 4 (which is 3) and 324 by 108 ( which is also 3). Then all you have to do is multiply 12 by 3 which is 36!
I hope this helps, and have a great day! :)

Solve for x: -4x - 12 < 12
Seems like you are an imposter ;). This is Middle School math.
Anyways...
Answer:
x>6
Step-by-step explanation:
-4x-12<12
Add 12 on both sides.
-4x<24
Divide both sides by -4 to isolate x. Remember that if you are dividing by a negative, flip the sign!
x>6

Joey is measuring the amount of time it takes for a frisbee to fly through the air he uses a stopwatch to time it and find that it takes 4.82 seconds if it actually takes 5.05 seconds then what is the percent error in Joey's measurement to the nearest 10th of a percent
Answer:percent error in Joey's measurement to the nearest 10th of a percent =- 4.6%
Step-by-step explanation:
Step 1
Time as recorded by the stopwatch = 4.82 seconds
Real Time it takes for a Frisbee to fly through the air =5.05 seconds
percent error = Measured value – True Value /True value x 100.
= 4.82 - 5.05 / 5.05 x 100
=-0.23/5.05
=-0.0455 x 100
=4.5544%
Rounding to nearest 10th of a percent = - 4.6%

Which list shows the integers in order from lest to greatest ? -8 , -5 , 0 , 2 , 6 0 , 2 , -5 , 6 , -8 -5 , -8 , 0 , 2 , 6 0 , -8 , -5 , 2 , 6
Answer:
a.-8,-5,0,2,6
Step-by-step explanation:
We have to find the list which shows the integers in order from least to greatest.
We know that when we left side of zero on a number line then the values decrease and we go right side of zero then the value increases.
a.-8,-5,0,2,6
-8<-5<0<2<6
Hence, it is true.
b.0,2,-5,6,-8
-8 least and 6 is greatest
Therefore, it is false.
c.-5,-8,0,2,6
It is false.
d.0,-8,-5,2,6
It is false.
Option a is true,

Answer:

Step-by-step explanation:
Answer:
y = 4[tex](2)^{x}[/tex]
Step-by-step explanation:
An exponential function in standard form is
y = a[tex]b^{x}[/tex]
Substitute points from the graph into the equation to find a and b
Using (0, 4 ), then
4 = a[tex]b^{0}[/tex] [ [tex]b^{0}[/tex] = 1 ], so
a = 4
y = 4[tex]b^{x}[/tex]
Using (1, 8 ), then
8 = 4[tex]b^{1}[/tex] = 4b ( divide both sides by 4 )
b = 2
y = 4 [tex](2)^{x}[/tex] ← exponential equation

y=9/8
what do i write i need help so i can do this
Answer:
Step-by-step explanation:
First what you want to is subtract 7 from both sides, then you want to divide -2/3 from both sides.
To isolate the variable you need to remove the terms from the side with the variable to remove the terms you need to do the same thing on both sides.
-2/3n + 7 = 15
First step is to subtract 7 from both sides to get:
-2/3n = 8
Now divide both sides by -2/3 to get:
N = 8 / -2/3
Then to solve for n simplify to get:
N = -12

Answer:
-9/3 or -3
Step-by-step explanation:
[tex]Slope= \frac{y_{2} -y_{1} }{x_{2}- x_{1} }[/tex]
Lets start with the y's, substitute:
-6-3=-9
Then the x's, substitute:
5-2=3
Substitute back into the fraction:
-9/3 or
-3
Answer:
m = -3
Step-by-step explanation:
y2-y1
--------
x2-x1
-6-3/5-2
-9/3
-3
Therefore, your answer for slope would be m = -3

Simplify the following expression
Simplifying expressions
8th grade math
Algebra 1
Can someone explain why
(-5k^2m)(2km)^4(3km^4)^2
——————————————
k^2m^3
Simplifies to -720k^6m^10
But 3m/m^4 simplifies to 3/m^2
Even though their both fractions how come only one stays a fraction? What’s the difference so I can figure out in the future?
Answer:
1. [tex]\frac{(-5k^{2}m)(2km)^{4} (3km^{4}) ^{2}}{k^{2}m^{3}}[/tex] = -720[tex]k^{6}m^{10}[/tex]
2. [tex]\frac{3m}{m^{4} }[/tex] = [tex]\frac{3}{m^{3} }[/tex] (or 3[tex]m^{-3}[/tex])
Step-by-step explanation:
1. The given expression is:
[tex]\frac{(-5k^{2}m)(2km)^{4} (3km^{4}) ^{2}}{k^{2}m^{3}}[/tex]
With respect to the principle of exponential, we have;
[tex]\frac{(-5k^{2}m)(2^{4}k^{4} m^{4})(3^{2}k^{2}m^{8})}{k^{2} m^{3} }[/tex] = [tex]\frac{(-5k^{2}m)(16k^{4} m^{4})(9k^{2}m^{8} }{k^{2}m^{3} }[/tex]
Applying the law of indices,
= [tex]\frac{(-5*16*9)(k^{2+4+2})(m^{1+4+8}) }{k^{2} m^{3} }[/tex]
= [tex]\frac{-720k^{8} m^{13} }{k^{2}m^{3} }[/tex]
= -720[tex]k^{8}m^{13}[/tex] x [tex]k^{-2} m^{-3}[/tex]
= -720[tex]k^{8-2} m^{13-3}[/tex]
= -720[tex]k^{6}m^{10}[/tex]
2. [tex]\frac{3m}{m^{4} }[/tex]
divide the numerator and denominator with common factor m,
= [tex]\frac{3}{m^{3} }[/tex]
This can not be simplified further since there are no more common factors, so that;
[tex]\frac{3m}{m^{4} }[/tex] = [tex]\frac{3}{m^{3} }[/tex] (or 3[tex]m^{-3}[/tex])
Jill brought 6 1 3 boxes of carrot muffins for a bake sale. Mike brought 1 3 4 boxes of apple muffins.
Answer: 8 1/12
Step-by-step explanation:
The remainder of the question is:
What is the total number of boxes of apple Jill and Mike brought to the bake sale?
This will be the addition of both fractions which will be:
= 6 1/3 + 1 3/4
The LCM of 3 and 4 is 12
= 6 4/12 + 1 9/12
= 7 13/12
= 8 1/12

r = 2
Step-by-step explanation:
A) √121 + 3/5 + 2/5 = 11 + 1 = 12
B) √100 - 3 -7 = 10 - 3 - 7 = 0
r) 1/2 - 1/2 + √4 = 2
$100 into a savings account that earns 6% annual intrest compounded monthly for 5 years
Answer:
$141.94
Step-by-step explanation:
Basically multiply 100 by .06, add the answer too 100. Which gets 106.
Multiply 106 by .06 and add the answer to 106, do that 5 times(which counts as the five years) and vuala, you got your answer.
And since it said an annual
interest, then the monthly compounding doesn't matter.
