Answer:

752

Step-by-step explanation:

7/20 of 2880 = 1008

2/9 of 2880 = 640

1/6 of 2880 = 480

2880 - 1008 - 640 - 480 = 752

A yo-yo factory has fixed operating costs of $5000 per day plus costs of $2 per yo-yo produced. If a yo-yo sells for $5.50, what
Jlenok [28]

Answer:

1429

Step-by-step explanation:

Break even is expressed as:

5000+2x = 5.5x

5000=5.5x-2x

5000=3.5x

\frac{5000}{3.5} = \frac{3.5x}{3.5}

1428.57=x

Since you cannot sell a fractional yo-yo, round up to 1429

The client is to receive cyclophosphamide (Cytoxan) 50 mg/kg intravenously in divided doses over 5 days. The client weighs 176 p
marishachu [46]

Answer:

800 mg

Step-by-step explanation:

As the excerpt states that the client weights 176 pounds and is to receive cyclophosphamide (Cytoxan) 50 mg/kg, we have to convert 176 pounds to kg:

1 kg → 2.20 pounds

  x   ←  176 pounds

x= (176 pounds * 1 kg)/2.20 pounds= 80 kg

Now, we have to determine the total amount of cyclophosphamide (Cytoxan) that the client has to receive:

50 mg/kg

For 80 kg: 80 kg *50 mg/kg= 4,000  mg

As the dose is divided over 5 days:

4,000 mg / 5= 800 mg

The client will receive 800 mg of cyclophosphamide each day.

Murrr4er [49]

Answer:

Step-by-step explanation:

Hello, please consider the following.

x^2+x-42\\\\\text{The sum of the zeroes is -1=-7+6 and the product is -42=-7*6.}\\\\\text{So, we can factorise.}\\\\x^2+x-42\\\\=x^2+7x-6x-42\\\\=x(x+7)-6(x+7)\\\\=(x+7)(x-6)

So, the possible dimensions of the rectangle are (x+7) and (x-6).

Thank you.

If 5 pizzas cost $60, how much will 9 pizzas cost?<br> A $98<br> B $108<br> $110<br> D $112
frozen [14]

We can find the cost of ONE pizza, by dividing the price (60) by the amount (5):

60 / 5 = 12.

So each pizza costs 12 dollars, now to multiply that by 9:

12 * 9 = 108.

9 Pizzas cost 108 dollars.
