Answer:

She takes 11 grams more protein for breakfast than for a snack.

Step-by-step explanation:

Consider the provided information.

Gina had a scrambled egg and a cup of low-fat milk for breakfast.

She had an oat bran muffin for a morning snack.

First round up the numbers as shown below:

Food Protein (in grams) 1 scrambled egg 6.71 ≈ 7

1 cup shredded wheat cereal 5.51 ≈ 6

1 oat bran muffin 3.98 ≈ 4

1 cup low-fat milk 8.22 ≈ 8

Protein in Breakfast = a scrambled egg + a cup of low-fat milk

Protein in Breakfast = 7+8 = 15

Morning snack she had an oat bran muffin.

Protein in Morning snack = 4

Now we need to find how many more grams of protein did Gina have for breakfast than for a snack?

So subtract them as shown below:

15-4 = 11

Hence, she takes 11 grams more protein for breakfast than for a snack.

Kendra found this relationship between the quantities in the table.
slava [35]

Answer:

Kendra should have multiplied the x-values by 75 to get the y-values

Step-by-step explanation:

Given

Table

X|| Y

1 || 75

2 || 150

3 || 225

4 || 300

5 || 375

Given that Kendra multiply x by 7.5 to get y

The relationship of x and y can be calculated as thus;

y = rx

Where y and x are the values at the y and x column respectively and r is the constant of proportionality

When y = 75, x = 1.

Plug in these values in the above formula

y = rx becomes

75 = r * 1

75 = r

r = 75

When y = 150, x = 2

150 = r * 2

Multiply both sides by ½

150 * ½ = r * 2 * ½

75 = r

r = 75

When y = 225, x = 3

225 = r * 3

Multiply both sides by ⅓

225 * ⅓ = r * 3 * ⅓

75 = r

r = 75

Notice that r remains 75 and the difference between y values is 75

If you apply these formula on when y = 300 or 375 and when x = 4 or 5, the constant of proportionality will remain The value of 75.

Hence, Kendra mistake is that; Kendra should have multiplied the x-values by 75 to get the y-values

Whats longer 3 hours or 175 minutes
avanturin [10]
3 hours is longer than 175 minutes. An hour is 60 minutes long, so just multiply that by 3 and compare your answer to 175.

60 x 3 = 180
180 > 175

Therefore, 3 hours is longer than 175 minutes.

Hope this helps!
