A certain common formula converts the numbers in Box 1 to the corresponding ones in Box 2. Another formula then converts the numbers in Box 2 to the corresponding ones in Box 3:
IMAGE
If we wanted to convert a number m in Box 1 directly to the corresponding number in Box 3, we could use the formula.
A. 3m + 2
B. 3m x 3
C. 3(m + 2)
D. m + 2 x 3
The formula to convert numbers from box 1 to box 3 is (c) 3(m + 2)
Represent the numbers in box 1 with m.
The numbers in box 2 are three times the numbers in box 1.
So, the formula to convert numbers in box 1 to box 2 can be represented as:
[tex]f(m) =3m[/tex]
The numbers in box 3 are 6 more than the numbers in box 2.
So, the formula to convert numbers in box 2 to box 3 can be represented as:
[tex]g(m) =f(m) + 6[/tex]
Substitute 3m for f(m)
[tex]g(m) =3m + 6[/tex]
Factor out 3
[tex]g(m) =3(m + 2)[/tex]
Hence, the formula to convert numbers from box 1 to box 3 is (c) 3(m + 2)

Andre and Ronnie used a stopwatch to record the amount of time it took a golf ball to roll down a three-story ramp. Andre's ball took 1.635 seconds and Ronnie's ball took 1.625 seconds. Which of the following is true? A When rounded to the nearest tenth, both times are the same. B When rounded to the nearest hundredth, both times are the same. C Both times are closer to 1.7 than 1.6. D Both times are halfway between 1.63 and 1.64.
Answer:
The answer would be A
Step-by-step explanation:
This is because when you take 1.625 it rounds back to 6 because 2 isnt more then 5 or 5 so it wouldn't round just like 1.635. I believe thats the answer im not positive
The O! Natural Company sells a juice in 1 gallon bottles. The current retail price of the juice is $3.50 for 1 gallon. In order to remain competitive, the company will decrease the price to $3.20. Suppose the company's cost per 1 gallon is $2.70. What is the markup if they sell each gallon at $3.20?
Answer:
A) that’s a $.30 decrease so to find the percent you do the formula
3.50x=.30
3.50x/3.50=.30/3.50
X=.0857
.0857=8.57% so$3.20 is 8.57% of $3.50
B) $3.20 markup=18.5% and $3.50 markup is 29.6% but this depends on where you round up at and you get the answer the same way, with the formula $2.70x=.80 because $3.50-$2.70 =.80

Answer:
1. : 4
2. : 15
Step-by-step explanation:
Factors for 20: 1, 2, 4, 5, 10, 20
Factors for 32: 1, 2, 4, 8, 16, 32
Looking at the factors, we can see that the largest factor 20 and 32 have in common is 4. The answer isn't 1 or 2 because we are looking for the greatest common factor. This means we are looking for the largest of the factors which they both share.
Factors of 45: 1 , 3 , 5 , 9 , 15 , and 45.
Factors of 75: 1 , 3 , 5 , 15 , 25 and 75
Looking at these factors, we can see that 15 is the largest factor that 45 and 75 both share. The answer is not 1, 3, or 5 because we are again looking for the GREATEST common factor.

[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{ - \frac{10}{27}}}}}} [/tex]
Step-by-step explanation:
[tex] \sf{ - 3 \frac{1}{3} \div 9}[/tex]
Convert the mixed number into improper fraction
[tex] \longrightarrow{ \sf{ - \frac{ 3 \times 3 + 1}{3} \div 9}}[/tex]
[tex] \longrightarrow{ \sf{ - \frac{ 9 + 1}{3} \div 9}}[/tex]
[tex] \longrightarrow{ \sf{ - \frac{ 10}{3} \div 9}}[/tex]
Multiply the dividend by the reciprocal of the divisor. Reciprocal of any number or fraction can be obtained by interchanging the position of numerator and denominator
[tex] \longrightarrow{ \sf{ - \frac{ 10}{3} \times \frac{1}{9}}} [/tex]
To multiply one fraction by another, multiply the numerators for the numerator and multiply the denominators for its denominator
[tex] \longrightarrow{ \sf{ - \frac{10 \times 1}{3 \times 9}}} [/tex]
[tex] \longrightarrow{ \sf{ - \frac{10}{27}}} [/tex]
Hope I helped!
Best regards! :D

(5.81 x 10 to the power of 6),first 10 to the power of 6 is 1,000,000,now times 5.81 which is 5,810,000.
10 to the power of 7 is 10,000,000, now times 4.22, which is 4,220,000.
5,810,000 + 4,220,000 = 10,030,000
