Please give me brainliest, I really need it.
First, we have to calculate how much time it takes Laine to read one page.
240 / 200 = 6 / 5 (six fifths of a minute)
Then, we need to find out how much time it takes her to read 25 pages.
25 * 6 / 5 = 150 / 5 = 30 minutes
A: It will take Laine 30 minutes to read 25 pages at the same rate.
Answer:
x=lengthNEW-lengthOLD
Step-by-step explanation:
The length of the tree used to be only 1.85m. We call this the old length value of the tree, or in short: "lengthOLD"
Next the tree grew to be 5.30m. We call this the new length value of the tree because this measurement was taken later in time, and so after the first measurment. In short: "lengthNEW" is always the newwest value.
To calculate how much the tree has grown, you need to subtract the two lengths. It alway goes in this way:
The newwest number minus the old number.
In this case: x=lengthNEW-lengthOLD
Answer:
The amount of salt required is 0.3685 grams.
Step-by-step explanation:
20.9% of 1 gram of salt is chlorine, which means the grams of chlorine in 1 gram of salt are
Now, to make 220 ppm solution, it must be that
where is the grams of chlorine required.
We rearrange the equation and solve for
since 1 gram of salt has 0.209 grams of chlorine, 0.07702g of chlorine corresponds to
Thus the amount of salt required is 0.3685 grams.
