Answer:

2.23

Step-by-step explanation:

0.48 for the first ounce, and then 0.20 for the rest.

0.48 + (0.20 x 3) = 1.08

.95 ounces? We round that to 1.00 ounces.

1.08 + 1 = 2.08 BUT

<em>It's .95, isn't it? We need to do another part. </em>

.95 divided by 0.20 (the ounces by the cost) = 4.75

You need to convert the 4.75 to a fraction, so 4.75 becomes 4 3/4.

subtract the missing amount (to make the fraction equal to 1) from the cost, so

1/4 of 0.20 is 0.5. Subtract 0.5 from 0.20 makes it 0.15.

<em>Finally, add the costs.</em>

2.08 + 0.15 = 2.23.

Suppose you start at the origin, move along the x-axis a distance of 4 units in the positive direction, and then move downward a
Zanzabum

Answer:

(4,0,-5)

Step-by-step explanation:

Since we move 4 points along +ve x-axis so,  x coordinate is 4

We did not move any point along y-axis so  y coordinate is 0

we moved 5 points along -ve z-axis so z coordinate is -5

so our position is (x,y,z) = (4,0,-5)

Brandon follows a 2,800 calorie per day diet. He has 11 servings of breads and cereal, which average 140 calorie each. Yesterday
JulijaS [17]
Breads/cereals;

11 * 140 = 1540 calories

Fruits/vegetables;

9 * 60 = 540 calories

Meat/milk;

x * 180 = 2800 - (1540 + 540)

180x = 2800 - 2080

180x = 720

x = 4 servings
