Answer:

290

Step-by-step explanation:

4200 x 2.3 x 3

P x r x t = I.

$100 x 5 percent x 1 year = $5.

$100 x .05 x 1 year = $5.

so 4200 x 2.3 x 3 =289.8 or 290 for you

Use the Babylonian method for your next estimate for square root 175 by using 13.0463 as your guess. What is your result
viva [34]
Answer:  13.2300 is the next guess

To use the Babylonian method, you first start with your guess of 13.0463. Then, you add to it the original number divided by 13.0463.

It would look like this:
13.0463 + 175/13.0463 =26.460006

Then, you divide this number by 2. 
The result is 13.2300

This value is closer to the correct square root of 175.

soldier1979 [14.2K]

Answer:

\frac{9}{20} students.

Step-by-step explanation:

We have been given that of the students that attended Roosevelt Elementary 6/8 of the school play a sport. Of the students are playing a sport 3/5 of the students are also involved in the drama club.

To find the students are both play a sport and a part of the drama club, we need to find 3/5 part of 6/8 as:

\text{Students who play a sport and a part of the drama club}=\frac{6}{8}\times \frac{3}{5}

\text{Students who play a sport and a part of the drama club}=\frac{3}{4}\times \frac{3}{5}

\text{Students who play a sport and a part of the drama club}=\frac{3\times 3}{4\times 5}

\text{Students who play a sport and a part of the drama club}=\frac{9}{20}

Therefore, \frac{9}{20} students play sport and part of the drama club.

one dozen doughnuts cost $6.00. if the unit price is the same, how many doughnuts can be bought with $16?​
kodGreya [7K]

32 doughnuts can be bought with $16.

Step-by-step explanation:

One dozen doughnuts = $6.00

One dozen = 12

$6.00 = 12 doughnuts

$1.00 = \frac{12}{6.00} = 2

Therefore, 2 doughnuts can be bought for $1.

For $16 dollars;

No. of doughnuts = Amount * Doughnuts per dollar

No.\ of\ doughnuts=16*2\\No.\ of\ doughnuts=32

32 doughnuts can be bought with $16.

Aluminum is a highly reactive metal that oxidizes when exposed to air. Which of these would be a good first step in balancing th
klasskru [66]

Answer:

first step to balance the equation is :

multiply AL by 2 to match the amount of aluminum on the other side

balanced equation : 4 Al +3O2 → 2 ALO3

Step-by-step explanation:

Al + O2 → Al2O3

first step to balance the equation is :

multiply AL by 2 to match the amount of aluminum on the other side

but then you have to deal with the amount of O from both sides, we need to find the least common multiple between 2 and 3 which is 6

the best thing to balance the equation is to multiply O2 by 3 and O3 by2, then deal with the amount of AL which is 4 on the other side. last step is to multiply AL by 4 to balance the equation.
