Answer:

The answer to this is: C

$y - 6 = -4(x +1)$

Step-by-step explanation:

Using the formula:

$y-y_1=m(x-x_1)$

and inserting what we are given:

m = - 4

(m is the symbol which represents slope)

(-1, 6)

This point coordinate represents our:

$x_1 = -1$

$y_! = 6$

When inserted into our formula (point slope form formula)

It will look like this:

$y - (6) = -4(x - (-1))$

Then solve it from there!

(There is a double negative, which will make it positive)

Giving you:

$y - 6 = -4(x +1)$

The purple pathers helipad is 1/3 of a mile from the control center we'll drop the food when it's 1/4 of the way there how many

AlexFokin [52]

Answer:

1/12 of a mile.

Step-by-step explanation:

1. Find a common denominator. In this instance, we can use the denominator of 12 because both 3 and 4 are multiples of 12.

2. Multiply each fraction (numerator and denominator) to convert them.

1/3(4/4) = 4/12

1/4(3/3) = 3/12

3. Subtract.

4/12－3/12 = 1/12

jacob wants to buy packets of fruit juice. on tuesday, he buys 8 packets of orange and 6 packets of Apple the packets make a tot

ioda

Answer:

Each packet of orange can make 2 cups of juice and each packets of Apple can make 3 cups of juice.

Step-by-step explanation:

Let number of cups of juice in each packet of orange be 'x'.

Let number of cups of juice in each pack of apples be 'y'.

Given:

On Tuesday;

Number of packets of oranges = 8

Number of packets of apples = 6 packets.

Amount of fruit juice = 34 cups

So we can say that;

Amount of fruit juice is equal to sum of Number of packets of oranges multiplied by number of cups of juice in each packet of orange and Number of packets of apples multiplied by number of cups of juice in each pack of apples.

framing in equation form we get;

$8x+6y=34 \ \ \ \ equation \ 1$

On Wednesday;

Number of packets of oranges = 14

Number of packets of apples = 6

Amount of fruit juice = 46 cups

So we can say that;

framing in equation form we get;

$14x+6y=46 \ \ \ \ equation \ 2$

Now Subtracting equation 1 from equation we get;

$14x+6y-(8x+6y)=46-34\\\\14x+6y-8x-6y=12\\\\6x=12$

Now dividing both side by 6 we get;

$\frac{6x}{6}=\frac{12}{6}\\\\x=2\ cups$

Now we will substitute the value of 'x' in equation 1 we get;

$8x+6y=34\\\\8\times2+6y=34\\\\16+6y=34$

Subtracting both side by 16 we get;

$16+6y-16=34-16\\\\6y= 18$

Now dividing both side by 6 we get;

$\frac{6y}{6}=\frac{18}{6}\\\\y=3$

Hence Each packet of orange can make 2 cups of juice and each packets of Apple can make 3 cups of juice.

Answer:

B. $\frac{60 hours}{1} \times \frac{1 day}{24 hours}$

Step-by-step explanation:

Converting 60 hours to days:

24 hours = 1 day

60 hours = x day

Cross multiply

$24 hours \times x = 60 hours \times 1 day$

Divide both sides by 24 hours

$x = \frac{60 hours \times 1 day}{24 hours}$

Thus,

$\frac{60 hours \times 1 day}{24 hours} = \frac{60 hours}{1} \times \frac{1 day}{24 hours}$

The expression that shows how to convert 60 hours to days is:

$\frac{60 hours}{1} \times \frac{1 day}{24 hours}$

A) 20 milligrams of the drug lincomycin is to be given for each kilogram of a person's weight the drug is be mixed with 250 cc o

krok68 [10]

Answer:

you need to convert pounds to kilograms. 196 pounds is 88.904 kilograms. The directions tell you that 20 milligrams of the drug is to be administered for each kilogram of a person's weight. Now you need to multiply 88.904 by 20. That should give you 1778.08 milligrams of lincomycin. You would then mix 250 cc's of saline solution to the 1778.08 milligrams of lincomycin; but I think its just asking you how much lincomycin to administer.

at what rate per minute should the 250 cc solution be adminstered
