Omar is born weighing 8 pounds, and 3 ounces. The doctor says he should gain 5 ounces each week for 4 weeks. How much should omo
Monica [59]

Let's convert 8 pounds and 3 ounces, into all ounces.

So we know one pound = 16 ounces.

1 lb = 16 oz.

Now since Omar is 8 pounds + 3 ounces, we multiply 16 by 8, and add on the 3:

16 * 8 = 128

128 + 3 = 131

So Omar weights 131 ounces when he was born.

Now Omar has to gain 5 ounces each week, for 4 weeks. This means in total, he'll have to gain 5*4=20 ounces in 4 weeks.

Add them together:

131 + 20 = 151 oz OR 9 7/16 lb.

You would like to make a nutritious meal of eggs, edamame, and elbow macaroni. The meal should provide at least 40 g of carbohyd
arsen [322]

Answer:

2x + 12y + 43 ≥ 40

17x + 12y + 8z ≥ 20

14x + 6y + z ≤ 50

x ≥ 0

y ≥ 0

z ≥ 0

Step-by-step explanation:

given:

Cost Eggs = $2

Cost of edema = $5

cost of  elbow Macaroni = $3

Lets eggs = x,

edamame = y

elbow macaroni = z

TC = 2x+5y+3z

Therefore;

2x + 12y + 43 ≥ 40

17x + 12y + 8z ≥ 20

14x + 6y + z ≤ 50

x ≥ 0

y ≥ 0

z ≥ 0

the first objective is to make sure the total cost is subject to the required nutritional requirements.

So the total cost function (TC) is denoted by the number of servings multiplied for each costs. Eggs cost $2, edamame $5, and macaroni $3.

The problem subjects that each meal contains at least 40g of carbohydrates (this is the condition).

to get this we need to add what each meal component adds to the total, eggs add 2g of carbs, edamame 12g, and macaroni 43g.

Same should be done for protein, we require at least 20 grams of protein,  Eggs add 17g, edamame adds 12g, and macaroni adds 8g.

and lastly we don't want more than 50 grams of fat,  Eggs add 14g, edamame add 6g and macaroni 1g.

Your friend simplifies the following problem. Describe what error was made. No credit for just the correct final answer, we are
kenny6666 [7]

The error was made when he added the number in the radical expression in the computation, despite the fact that the numbers do not have the same base.

<h3>What are the radical expressions?</h3>

Any expression that contains a radical symbol is considered a radical expression. To find the square roots, cubic roots, and higher, radical symbols are used. For example, √7, √6, and √11 are in the radial form.

The expression is given in the question following:

4√5 + 7√3

11√8

The error was made in that he add the number in the radical expression in the calculation while the terms are not the same base.

the triangle above is changed so that the Exterior angle measures 128 degrees. How does this affect angles B and C?
Readme [11.4K]

Answer:

That means that B+C=128°

Step-by-step explanation:

(I think that there's an error in the task itself though C + the outer angle should be 180°)

Find the slope and the y-intercept of the line y=-2/5x+5
nexus9112 [7]

Answer:

slope is -2/5, y intercept is (0,5)

Step-by-step explanation:

The slope is the number in front of the x, or how steep the line is on the graph. In this case, it is -2/5.

The y intercept happens when x = 0, so if you make x = 0 in this equation, you find that you are left with y = 5. That gives you the point (0,5) as your y intercept.
