Part A: After 3.75 days more milk will need to be purchased. I know this because 4 can only go into 15 3.75 times.

Part B: If half as much milk is used each day after 7.5 days more milk will need to be purchased. I know this because 2 can go into 15 7.5 time.

Part A: The coffee shop can go 3 days until they need to purchase more milk. If you divide 15 by 4 you get 3.75. So, you wouldn't have enough milk to go through another day. You can also count by four until you get to 12. You wouldn't be able to go any higher.

Part B: The coffee shop will now be able to a week until buying milk. If you divide 15 by 2 you get 7.5. You can also count by two until you get to 14.

Hope this helps! :)

Can u plz help me?...

Answer:

a 4 1/5

b 7 7/24

Step-by-step explanation:

a 7/9 * 5 2/5

Change the mixed number to an improper fraction

7/9 * (5*5+2)/5

7/9 * 27/5

Rewrite

7/5 * 27/9

7/5 * 3

21/5

Change this back to a mixed number

5 goes into 21 4 times (4*5 = 20 ) with 1 left over

4 1/5

b 1 3/4 * 4 1/6

Change to improper fractions

(4*1+3)/4 * (6*4+1)/6

7/4 * 25/6

175/24

Change back to a mixed number

24 goes into 175 7 times (7*24 =168 ) with 7 left over

7 7/24

Which of the following is correctly written in Standard Form?

Marta_Voda [28]

9514 1404 393

Answer:

(b) 4x- 3y = 6

Step-by-step explanation:

Standard form is ...

ax +by = c

where a, b, c are mutually prime integers and a > 0. (If a=0, then b>0.)

A: slope-intercept form with variables on both sides of the equal sign.

B: standard form

C: coefficients aren't integers

D: coefficients aren't integers; leading coefficient is negative.

Find the standard form of the equation for the circle with the following properties.

nataly862011 [7]

Answer:

$(x+6)^2+(y+\frac{7}{6})^2=\frac{49}{36}$

Step-by-step explanation:

So, we know that the center of the circle is at (-6, -7/6).

To find the equation of our circle that is tangent to the x-axis, we just need to find the vertical distance from our center to the x-axis.

Our center is at (-6, -7/6). The vertical distance from this to the x-axis directly above will be (-6, 0).

So, find our distance by subtracting our x-values:

$d=r=0-(-7/6)$

Subtract:

$d=r=7/6$

So, our distance, which is also our radius, will be 7/6.

Now, we can use the standard form for a circle, which is:

$(x-h)^2+(y-k)^2=r^2$

Where (h, k) is the center and r is the radius.

Substitute -6 for h, -7/6 for k, and 7/6 for r. This yields:

$(x+6)^2+(y+\frac{7}{6})^2=\frac{49}{36}$

We can confirm by graphing (using a calculator):

A new health drink has 130% of the recommended daily allowance (RDA) for a certain vitamin. The RDA for this vitamin is 30 mg. H

dsp73

Answer:

39 mg

Step-by-step explanation:

To get the number of milligrams, all we have to do is to find 130% of the RDA

mathematically, we have this as;

130% of 30

= 130/100 * 30 = 39 mg

Given that slope = -1 and a point (3,-1), write an equation in slope-

stealth61 [152]

Y=Mx+b

Slope/M= -1
X= 3
Y= -1

-1 = -1(3)+b

-1 = -3 + b

Add +3 to -3 and -1 to cancel -3 out to get (b)

-3+3 = 0 cancel it

-1 +3 = 2

So, b = 2

In an equation it will be written as

y= -1x + 2

In standard form it will be

1x + y = 2

But your official answer will be

B= 2
Y= -1x+2
