Bogdan [553]

Let x represent the number of liters of 50% acid Theresa puts into the mix. The the number of liters of 30% acid will be (420-x). The total amount of acid in the final solution will be ...
0.50x + 0.30(420-x) = 0.45(420)
0.20x + 126 = 189 . . . . . . . . . . . . . . . simplify
0.20x = 63 . . . . . . . . . . . . . . . . . . . . . subtract 126
x = 63/0.20 = 315 . . . . . . . . . . . . . . . liters of 50% solution

What is the width of a rectangle with length 14cm and area 161 cm^2

Inessa05 [86]

Answer:

Step-by-step explanation:

The area of a rectangle can be found with the formula $A = l*w$ , where $l$ is the length of the rectangle and $w$ is the width.

From the given problem statement, we know that $l = 14$ and $A = 161$ , so we can fill in those values in the formula anbd solve for $w$ to get the width:

$A = l*w$

$161 = 14w$

Divide both sides by $14$ to isolate $w$ by itself:

$\frac{161}{14} = \frac{14w}{14}$

$w = 11.5$

Explain how your knowledge of place value helps you divide a number in the thousands by whole numbers to 10 give an example to s

lapo4ka [179]

Answer with Step-by-step explanation:

The value of a digit due to its position in a number is called as place value.

For example, there's a number

23450

2 is in ten thousands place and it has a place value of 20,000

3 is in thousands place and it has a place value of 3000

4 is in hundreds place and it has a place value of 400

5 is in tens place and has a place value of 50

0 is in unit or ones place and has a value of 0

When we divide the number by 10, we move every digit from its current place value to the right.

23450 divided by 10 = 2345

Now,

2 is in thousands place and it has a place value of 2,000

3 is in hundreds place and it has a place value of 300

4 is in tens place and it has a place value of 40

5 is in unit or ones place and has a place value of 5
