Answers

Answer:

Marcus should choose $2,400 plus 3% of sales.  

Step-by-step explanation:

He would choose the 2,400 plus 3% because he would earn more from the 2,400 plus 3% than the 1,750 plus 5.5%

2:3

4:6

6:9

18:27

Step-by-step explanation:

The constant of proportionality is 2:3 for this problem. On the second one, I saw that there was a 6. 6 was double what 3 is so I multiplied 2 by 2 and got 4. I basically did that with the rest of the problems. like the second one there is a 6 on the left side, 6 is 3 times the amount of two so I multiplied 3 by 3 to get 9. On the last one, there was a 27 on the right side. 27 is 9 times greater than 3 so I multiplied 2 by 9 to get 18 on the left side. I hope I didn't make it too confusing.

There were 1150 pounds of flour in the grain store. After most of the flour was sold, there were 230 pounds left. What was the percentage decrease of the grain store’s flour?

Answers

9514 1404 393

Answer:

  80% decrease

Step-by-step explanation:

The percentage change is found from ...

  percent change = ((new value)/(old value) -1) × 100%

  = (230/1150 -1) × 100%

  = -0.8 × 100%

  = -80% . . . . . a negative change is a decrease

The store's flour quantity decreased by 80%.

Answers:

Answers

Answer:

 (dependent)

(Incosistent)

(Independentt)

Step-by-step explanation:

{4x−2y=102x−y=5  

{y=2x−3−2x+y=−5

{2x−5y=143x+4y=10

The system of equations 2x−5y=14 and 3x+4y=10 have unique solution, so they are consistent independent.

What is a linear system of equations?

A system of linear equations consists of two or more equations made up of two or more variables such that all equations in the system are considered simultaneously. The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently.

A) The given system of equations are 4x−2y=10 and 2x−y=5

4/2 = (-2)/(-1)=10/5

2=2=2

Since, a₁/a₂ =b₁/b₂=c₁/c₂

The system of equations have infinitely many solution, so they are consistent dependent.

B) y=2x-3 and -2x+y=-5

Here, 2x-y-3=0 and -2x+y+5=0

2/(-2)=(-1)/1≠(-3)/5

-1=-1≠(-3)/5

Since, a₁/a₂ =b₁/b₂≠c₁/c₂

The system of equations are parallel, so they are inconsistent equations.

C) 2x−5y=14 and 3x+4y=10

Here, 2x-5y-14=0 and 3x+4y-10=0

2/3≠(-5)/4≠(-14)/(-10)

Since, a₁/a₂ ≠b₁/b₂

The system of equations have unique solution, so they are consistent independent.

Therefore, the system of equations 2x−5y=14 and 3x+4y=10 have unique solution, so they are consistent independent.

An office supply store sells pencils individually or by the case. Pencils purchased individually cost $0.97 each. One case of forty pencils costs $37.20. You have an annual budget of $95.00 for pencils.

Without exceeding the annual budget of $95.00, you can purchase _____ individual pencils.

Answers

0.97, add 7 to the five
You can purchase 97 individual pencils because 0.97*97=94.09 and if you do 98 it goes over the mark so 97 is the answer.

The mass of an average grain of table salt in a sample is about 3 x 10^-4 , and the mass of an average grain of rock salt in a sample is about 1.2 x 10^-2

Part A: Convert both masses to standard notation.

Part B: the mass of an average grain of rock salt is about 40 times the mass of an average grain of table salt. If you multiply the mass of table salt in standard notation by 40, what value do you get?

Part C: Is the value you got in part B equal to the mass of an average grain of rock salt? what does this mean?

Answers

Answer:

a. standard notation means in the number written in only number digits.

- to convert these multiply the two numbers given. FYI these are given in scientific notation, which is used so that numbers are easier to write.

remember: if the exponent is negative, you have move the decimal to the right. whereas, if the exponent is positive, you have to move the decimal to the left.

3 X 10^-4 --> move 4 places to the right.

answer - table salt: 0.0003

1.2 X 10^-2 --> move 2 places to the right.

answer - rock salt: 0.012

b. we know the standard notation of table salt is 0.003, so we simply multiply 40 by this.

answer - 0.0003 X 40 = 0.012

c. 0.012 = 0.012 (yes)

answer - yes the value i got in part B is equal to the mass of an average grain of rock salt. this shows that the mass of an average table salt is 1/40 times smaller than the mass of an average grain of rock salt.

- i am not sure about the "what does this mean" part. you can put whatever there but i put what i think it could be. i think it would be based on what notes you took on class.

Part(a),

The value of the masses in standard form is Rock salt: 0.012 and Table salt: 0.0003.

Part(b),

The multiplication is 0.012.

Part(c),

yielded a value equal to the mass of an average grain of rock salt. This demonstrates that the mass of an average grain of rock salt is 1/40 that of an average grain of table salt.

How to calculate the standard form?

a. Standard notation means in the number written in only number digits. To convert these multiply the two numbers given. FYI these are given in scientific notation, which is used so that numbers are easier to write.

If the exponent is negative, you have moved the decimal to the right. whereas, if the exponent is positive, you have to move the decimal to the left.

3 X 10⁻⁴ --> move 4 places to the right.

Table salt: 0.0003

1.2 X 10⁻² --> move 2 places to the right.

Rock salt: 0.012

b. We know the standard notation of table salt is 0.003, so we simply multiply 40 by this.

0.0003 X 40 = 0.012

C. 0.012 = 0.012 (yes)

Yes, the value I got in part B is equal to the mass of an average grain of rock salt. this shows that the mass of an average table salt is 1/40 times smaller than the mass of an average grain of rock salt.

I have an easy and quick question. So the picture shows an answered question but how do you know to divide? I just don't understand.....

Answers

Answer:

Ok so u know to divide bc u r trying to isolate the variable and that means undoing the function in this case 0.6 is multiplied to p so u do the opposite which is division

tada

Hope this helps :)

Pls give brainliest XD :)

Answer: You're looking for what P represents

Step-by-step explanation:

You start off with the equation

then subtract the number without the variable in this case both sides. Leaving 4.5-4.5= 0 and 22.5-4.5= 18

You also need to have p as P=n  (n= the number)

The equation 18/.6- 30, however you are looking for

0.6 divided by 18 which equal 0.33

so p=0.33

Jada walks up to a tank of water that can hold up to 12 gallons. When it is active, a drain empties water from the tank at a constant rate. When Jada first sees the tank, it contains 8 gallons of water. Four minutes later, the tank contains 5 gallons of water.

A) At what rate is the amount of water in the tank changing? Use a signed number, and include the unit of measurement in your answer.

B) How many more minutes will it take for the tank to drain completely? Explain or show your reasoning.

C) How many minutes before Jada arrived was the water tank completely full? Explain or show your reasoning.

Answers

1) Gallons per minute change is -2/3 gallons per minute since it decreases by 2 gallons in 3 minutes

2) we have 5 gallons and lose 2/3 gallons per minute

(2/3 gal/minute)(x minutes) = 5 gallons
x = 5(3/2) = 15/2 = 7.5 minutes to drain the other 5 gallons

3) There was 10 gallons when the tank is full
That is 3 gallons more than the 7 gals there when Jada arrived.
(2/3)(x) = 3
x = 3(3/2) = 9/2 = 4 1/2 minutes

The tank was full 4 1/2 minutes before Jada arrived
