I think the first one is an equation and it's a fraction with powers. (4 and 5).
The next one is a fraction and it is to the power of the number above you have to figure out if you have to multiply the powers with the number under it add them and divide or multiply them by the other number.
The third one is a multiplication problem you have to figure out what "r" is to figure it out you have to do 6 to the 2nd power to get r and you have to do 2 to the 6th power to get the other r. Then multiply the numbers together tp get the answer.

Step-by-step explanation:
(10-2)×(8+7) can be simplified to (8) × (15) = 120.
Another way of doing this problem is to apply the distributive property:

A standard number cube, numbered 1 through 6 on each side, is rolled 3 times. What is the probability of rolling a 2 on all three rolls? Enter the answer as a fraction
Answers
Answer:
1/(6^3)
Step-by-step explanation:
Each roll of the die constitutes a separate event.
These three events are independent.
The probability of rolling a 2 on the first throw is 1/6, since there is only one '2' among the six numbers on the die.
Because each roll is independent of the others, the probability of rolling a
2 1
on all three rolls is (1/6)(1/6)(1/6), or -----------

Answer:
A) solution 2 is more acidic than solution 1
Step-by-step explanation:
A chemist prepares two acid solutions:
Solution 1: 3 parts sulfuric acid to 7 parts water
Ratio of sulphur to water: 3/7 (3:7)
Solution 2: 4 parts sulfuric acid to 9 parts water
Ratio of sulphur to water: 4/9 (4:9)
___________________________________________________
Part A: (using ratios to determine which solution is more acidic)
First we make same denominator, since the denominators are 9 and 7, we have to find the lcm (lowest common multiple) they both have with is 63. To do that, we must multiply the denominators with either 7 or 9.
Solution 1: Numerator (3) multiplied by 9 and then denominator (7) multiplied by 9. This makes out fraction/ratio 27/63
Solution 2: Numerator (4) multiplied by 7 and then denominator (9) multiplied by 7. This makes out fraction/ratio 28/63
Since 28/63 (or just 28) is a larger quantity than 27/63 (or just 27) this means solution 2 is more acidic than solution 1.
Mathematical Line (Not sure what you would call this lol): 28 > 27
Part B: (Let 'y' amount of sulfuric acid mix with 'x' amount of water)
Equation of solution 1: y = 3/7x
Equation of solution 2: y = 4/9x
Please find attachment for graph.
Part C: Don't have a graph, sorry! (part a. method is more preferred to find more acidic because it gives the actual acidic amount.)

Player A is the most consistent, with a range of 5.
Answers
Answer: Player B is the most consistent, with an IQR of 3.5.
Step-by-step explanation:
For Player A, the IQR is 2 (Q3 - Q1 = 3 - 1 = 2).
For Player B, the IQR is 3.5 (Q3 - Q1 = 5 - 1.5 = 3.5).
Therefore, Player B is more consistent, as their IQR is larger, indicating less variability in their scores.

Answers
Answer:
[see answer below]
Step-by-step explanation:
"Perry saved 4 twenty-dollar bills, 2 ten-dollar bills, 3 dimes, and 2 pennies."
4 * 20 = 80
2 * 10 = 20
3 * 0.1 = 0.3
2 * 0.01 = 0.02
80 + 20 + 0.3 + 0.02 = $100.32
100.32 - 49.86 = 50.46

Samuel correctly determines the product by applying the distributive property. What is Samuel's answer?
Answers
1. Convert the mixed fraction into an improper fraction. 6 x 4 is 24+1=25 and you keep the denominator. Thus it would be -12 x 25/4.
2. Cancel out the common factor. 12 and 4 are both divisible by 4. -12 divided by 4 is -3, and the four would cancel out.
3. We are left with -3 x 25 which would be -75, because a negative integer multiplied by a positive integer is negative.

Answers
The equation (1 + 0.05)x = 7350 to find the actual number of steps you took today will be 7,000.
What is the percentage?The quantity of anything is stated as though it were a fraction of a hundred. A quarter of 100 can be used to express the ratio. Per 100 is what the term percent signifies. The symbol ‘%’ is used to symbolize it.
Your fitness tracker overestimates the number of steps you take by 5%. The trackers indicate that you took 7350 steps today.
Let x be the actual number of steps. Then the equation will be given as,
(1 + 0.05)x = 7350
x = 7350 / 1.05
x = 7,000
The actual number of steps you took today will be
(1 + 0.05)x = 7350
x = 7350 / 1.05
x = 7,000
The equation (1 + 0.05)x = 7350 to find the actual number of steps you took today will be 7,000.
