8^_/8^-4=8^9 I hate school btw

Mathematics
1 answer:
Monica [59]3 years ago
6 0
So 8 to the blank power divided by 8 to the negative 4 power=8 to the 9th power so

simplify
8^-4 means a reciprocal so 8^-4 means 1/(8^4) or 1/4096

8^9 is 134217728

so (8^x)/(1/4096)=134217728
multiply both sides by 1/4096
8^x=134217728/4096=32768
32768= 2^15 or 2*2*2*2*2*2*2*2*2*2*2*2*2*2*2 or since we know that 8=2*2*2 we can group the 2's this way  (2*2*2)(2*2*2)(2*2*2)(2*2*2)(2*2*2) we notice that there are 5 groups so 8^5 is the answer so x=5

Solve for t.<br><br> -5 − 2t = 3t
allsm [11]
T is equal to -1.
  1. <em>Add 2t to both sides of the equation.</em> -5 = 5t
  2. <em>Divide both sides of the equation by -5.</em> 1 = -t
  3. <em>Multiply both sides of the equation by -1.</em> -1 = t

Problem Set
insens350 [35]

5 liters (L) of 30% bleach solution contains 0.3×(5 L) = 1.5 L of bleach.

3 L of 50% bleach contains 0.5×(3 L) = 1.5 L of bleach, too.

Combined, you would have 8 L of solution containing 1.5 L + 1.5 L = 3 L of bleach, so the concentration of bleach is

(3 L) / (8 L) = 0.375 = 37.5%

<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3

Answer:

Let's solve your equation step-by-step.

3 / 4 y = 9

Step 1: Multiply both sides by 4/3.

(4 / 3 ) * ( 3 / 4 y ) = ( 4 / 3 ) * ( 9 )

y = 12

Answer:

y = 12

<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3

Insert 12 to the y value:

3 / 4 ( 12 ) = 9

9 = 9

True

<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3

The odds of rolling a die and getting an even number is 50%. Write out the success set and the sample set to use the definition
Charra [1.4K]

Answer:

It gets more complicated with a six-sided die. In this case if you roll the die, there are 6 possible outcomes (1, 2, 3, 4, 5 or 6). Can you figure out what the theoretical probability for each number is? It is 1/6 or 0.17 (or 17 percent).

What is the value of y if y = |– 5|?​<br><br> explain how you would get the answer step by step
Andrews [41]

Answer:

y=5

Step-by-step explanation:

The answer is 5 because that sign around the -5 is the absolute value sign. What the absolute value sign does is it measures the distance from 0 the number is. Since the number -5 is 5 units away from the number 0, then y=5.
