Answer:
6) a) 69 b) 97 c)86 d)71
7) A.
Step-by-step explanation:
6)
a) -1-[9(-8)]-2 = -1 - (-72) -2
= -3 + 72 = 69
b) 81 + 4² = 81 + 16
= 97
c)12×7 + 6÷3 =(12×7)+(6÷3)
= 84 + 2
=86
d)74 + 9 ÷ -3 = 74 + (9÷ -3)
= 74 - 3
= 71

I WILL MARK AS BRAINLIEST! Choose The inequality that represents the statement and then graph if on The line provided. Lacey has flown at least 120 miles.
Answer: Choice b) [tex]x \ge 120[/tex]
The graph will involve a closed filled in circle at 120, with shading to the right.
See the diagram below.
============================================
Explanation:
The phrasing "at least" means "that amount or more".
Saying "at least 120" is the same as "120 or more".
Therefore, x = 120 is the smallest x can be. That's why we go for [tex]x \ge 120[/tex] which says that either x = 120 or x > 120.
Visually, we'll plot a closed filled in circle at 120 on the number line. The shading will aim to the right to indicate all values larger than 120. The closed/filled in circle is to represent we include 120 (as opposed to an open circle where we exclude it).
Due to the fact that your teacher gave you a blank number line, the placement of 120 doesn't really matter.

Express each number as a product of its prime numbers.
1. 245
2. 510
3. 250
4. 1,089
5. 4,725
6. 900
18. 27,000
Answer:
Numbers expressed as a product of prime factors are as follows:-1. 245 = 5 × 7 × 7
2. 510 = 2 × 3 × 5 × 17
3. 250 = 2 × 5 × 5 × 5
4. 1089 = 3 × 3 × 11 × 11
5. 4725 = 3 × 3 × 3 × 5 × 5 × 7
6. 900 = 2 × 2 × 3 × 3 × 5 × 5
18. 27000 = 2 × 2 × 2 × 3 × 3 × 3 × 5 × 5 × 5

Answer:
it would be the last one
Step-by-step explanation:
hope it helps
Answer:
it would be the second one
Step-by-step explanation:

I WILL MARK AS BRAINLIEST! Write an equation that represents the points on the table
Step-by-step explanation:
y = ax +b
2 = 0a+ b => b = 2
4 = -2a + b
4 = -2a +2
2a = 2-4
2a = -2
a = -1
so, y = -x + 2
A car factory made 8 cars with a sunroof and 18 cars without a sunroof what is the ratio of the number of cars without a sunroof to the total number of cars?
Answer:
No of cars without sunroof=18
Total no of cars=18+8=26
Now,the ratio of cars without sunroof to total no of cars=18÷26
= 9÷13

3(x-5)+1=2+x Please put the work!!!!!!!!!!!!!!
Answer:
3(x-5)+1=2+x
3x-15+1=2+x
3x-x=2+15-1
2x=16
x=8
Answer:
x=8
Step-by-step explanation:
3(x-5)+1=2+x
Subtract 1 from both sides.
3(x-5)=1+x
Distribute the 3
3x-15=1+x
Add 15 to both sides.
3x=16+x
Subtract x from both sides.
2x=16
Divide both sides by 2.
x=8
I hope this helps!

Step-by-step explanation:
400 written as a product of its prime factors is 2 x 2 x 2 x 2 x 5 x 5.
Write 800 as a product of its prime factors.
Answer: 2 x 2 x 2 x 2 x 2 x 5 x 5
Explanation:
We start with the string 2 x 2 x 2 x 2 x 5 x 5
Then we tack on a "2 x" up front, or at the very left, so that we double the result. This is because the jump from 400 to 800 is "times 2".
So we go from 2 x 2 x 2 x 2 x 5 x 5 to 2 x 2 x 2 x 2 x 2 x 5 x 5
We can condense this into [tex]2^5*5^2[/tex]

Find the number that makes the ratio equivalent to 1:5.
6:
Answer:
box = 30
Step-by-step explanation:
You could set this up very formally as a proportion. It would look like this.
1/5 = 6/x
Now all you have to do is cross multiiply.
1*x = 5 * 6
x = 30
So the answer that goes in the box is 30
Or you could just say to yourself. "The 1 was multiplied by 6. What do I have to multiply the 5 by to keep the ratio the same?"
The answer is 6
6 * 5 = 30

A customer can drive around a track 60 times for $12. At this rate, how many times can the customer drive around the track for $8?
Answer:36 times for 8 dollars
Step-by-step explanation:
k so first you divide 54 and 12 =4.5 per dollar so you then multiply 4.5 and 8 to get the answer that =36 times for 8 dollars
Randall has 19 coins in his pocket. 12 are quarters, and the others are pennies. Randall selects two coins at random from his pocket replacing each coin before drawing the next coin. Which answer choice best describes this event?
A. This is an independent event because he is replacing the coin before drawing the next one.
B. This is a dependent event because he has different amounts of coins in his pocket.
C. This is an independent event because he could select a quarter and then a penny.

Step-by-step explanation:
the 125 doesn't actually matter so you can ignore that part.
since it is being divided by 14, the denominator of the fraction is 14. the remainder is 10, so the answer should be in the form of x 10/14, which the 1st answer is

A 100-meter sprint is a race using only the straight side of a race track. A 400-meter stick is a race that makes one complete a lap around a racetrack. Why are velocity and speed the same for a 100 m sprint but not a 400 m sprint
Answer
Because velocity and speed differ each other by direction, in a 100 m sprint race the person moves in a straight path without changing its direction where as in a 400 m race. The person moves in a lap around the race track and the direction changes as he turns according to the race track.

Q6)
Kerry's workday is 10 hrs. and works 40 hrs. per week, Kerry works for 4 days
Watson's workday is 8 hrs. and works 40 hrs. per week, Watson works for 5 days
Kerry: works 4 days and gets paid $ 12.75 per cat & grooms 15 cats per day, so Kerry makes = 4(12.75 × 15) = 4(191.25) = $ 765
Watson: works 5 days and gets paid $ 12.75 per cat & grooms 10 cats per day, so Watson makes = 5(12.75 × 10) = 5(127.50) = $ 637.50
∴ The difference between their weekly earning is 765 - 637.50 = $ 127.50
