A 3-ounce serving of tuna provides 21 grams of protein. Use equivalent ratios to find how many grams of protein are in 9 ounces
laila [671]

Answer:

63 grams of protein.

Step-by-step explanation:

3 ounces = 21 grams of protein.

Question is how many grams are in 9 ounces, you then have to find the ratio that you need to use to find out how many grams of protein are in 9 ounces. Therefor you divide the amount that we don't know the equal amount of grams by the amount we do know the equal amount of grams, giving us the ratio.

9 divided by 3 = ratio (3)

Then use the ratio for the grams of protein.

21 x 3 = 63.

The table shows data gathered by an environmental agency about the decreasing depth of a lake during the first few months of a d
Elanso [62]
(0,346)(2,344.8)
slope = (344.8 - 346) / (2 - 0) = -1.2 / 2 = -0.6

y = mx + b
slope(m) = -0.6
(0,346)...x = 0 and y = 346
now we sub and find b, the y int
346 = -0.6(0) + b
346 = b
so ur equation is : y = -0.6x + 346....with x being the number of weeks

after 4 weeks...
y = -0.6(4) + 346
y = - 2.4 + 346
y = 343.6 <==== after 4 weeks

after 9 weeks..
y = -0.6(9) + 346
y = -5.4 + 346
y = 340.6 <=== after 9 weeks

Original #: 950
New #: 1,520

If it is percent of increase, you would do new amount - original amount over original amount.

1,520 - 950 / 950 = 570 / 950
0.6 or 60%
