In purchasing food for a political rally, you erroneously order shucked medium-size Pacific oysters (which come 8 to 12 per U.S.

creativ13 [48]

Answer:

The order is short of 1440 to 2080 oysters

Step-by-step explanation:

Volume of ship = 150cm × 11cm ×23cm = 37950cm^3 = 37950/1000 = 37.95L

I U.S. pint = 0.4732L

37.95L = 37.95/0.4732 = 80 U.S. pint (to the nearest whole number)

Order contains 8 to 12 oysters per U.S. pint

80 U.S. pint contains 8×80 to 12×80 oysters = 640 to 960 oysters

Anticipated count should contain 26 to 38 oysters per U.S. pint

80 U.S. pint should contain 26×80 to 38×80 oysters = 2080 to 3040 oysters

Shortage = (2080 - 640) to (3040 - 960) oysters = 1440 to 2080 oysters

^Answer needed ASAP! Solve x2-6x=-5 by completing the square. show ALL work

ankoles [38]

Have a nice day, be safe and healthy :)

Hope this helped

formula:

(a+b)^2

= a^2+2ab+b^2

Here, we have x^2 (as in a^2)

and -6x (as in 2ab), which, we're missing the b^2

(I'm not really sure how to describe this but bare with me)

-6/2 (-6 is from the -6x) = -3 (the b)

-3^2 = -3*-3 which is equal to 9 (positive 9)

Writing it out -

x^2-6x+9 = -5

- Addition of inequality -

Since we add 9 to the left side, we have to add 9 to the right side; which gives us:

x^2-6x+9=4

Next, lets put the x^2-6x+9 as in (a+b)^2:

(x-3)^2 = 4

Then let's do the square root of equality (square rooting both sides) :

x-3 = 2

Finally lets add 3 to both sides

x = 5

THE ANSWER IS x=5

Have a nice day, be safe + healthy - Hope this helped

Which defines a circle

SIZIF [17.4K]

Circle is the locus of points equidistant from a given point, the center of the circle. The common distance from the center of the circle to its points is called radius. Thus a circle is completely defined by its center (O) and radius (R): C(O, R) = O(R) = {x: dist(O, x) = R}.
Easier explanation: A circle is a plane figure contained by one line such that all the straight lines falling upon it from one point among those lying within the figure are equal to one another.

Mr Jones has 20,000 to invest. He invests part at 6% and part at 7%, if hr earns 1,280 in interest after 1 year, how much did he

MariettaO [177]

Let x be the amount he invests at 6%

1280 = 0.06x + 0.07(20000 - x)
1280 = 0.06x + 1400 - 0.07x
1280 - 1400 = -0.01x
-120 / -0.01 = x
x = 12000

Therefore, he invests $12,000 at 6% and $8,000 at 7%
