Answer:

1.2 x 10^4 = 12,000

4.5 x 10^-3 = 4.5 x 1/(10^3) = 4.5/1000 = 0.0045

3.8 x 10^3 = 3,000

7.5 x 10^3 = 7,000

largest is 1.2 x 10^4

Hope this helps!!

Answer:

$(x',y')-->(x-3,y-2)$

Step-by-step explanation:

Notice that we can get from the x-coordinate of A, 1, to the x-coordinte of A', -2, by subtracting 3 from the x-coordinate of A. More formaly:

$1+a=-2$

$a=-2-1$

$a=-3$

Similarly, we can get from the y-coordinate of A, 5, to the y-coordinate of A', 3, by subtracting 2 from the y-coordinte of A. More formaly:

$5+b=3$

$b=3-5$

$b=-2$

Now we now that to get to A' from A, we need to subtract 3 to the x-coordinate of A and subtract 2 to the y-coordinate. Knowing this, we can create the expression to translate any point of the polygon ABCD to create the polygon A'B'C'D':

$(x',y')-->(x-3,y-2)$

Determine the slope of a line given points, (-5, 8) and (-8,5).

Contact [7]

Answer:

Step-by-step explanation:

We can use the slope formula

m = (y2-y1)/(x2-x1)

= (5-8)/(-8 - -5)

= -3/(-8+5)

= -3/-3

= 1

The question is:

A cake recipe calls for 550 grams of flour. About how many pounds of flour do you need? Use the conversion factors (1 ounce)/(28.4 grams) and (1 pound)/(16 ounces).

Answer:

About 1.2 pounds of flour is needed.

Step-by-step explanation:

Given that the cake recipe calls for 550 grams, we want to determine about how many pounds of flour we need.

This simply means we want to convert 550 grams to pounds.

First, we were given (1 ounce)/(28.4 grams)

This implies that

1/28.4 = x/550 ..............................(1)

Where x is 550 grams in ounce.

Solving (1)

28.4x = 550

=> x = 550/28.4

≈ 19.3662

That is 550 grams is equal to 19.3662 ounce

Next, we are given the ratio (1 pound)/(16 ounce). We then convert 19.3662 ounce to pound

Let y be 19.3662 ounce in pound

=> 1/16 = y/19.3662

16y = 19.3662

y = 19.3662/16

≈ 1.2

That is 19.3662 ounce is equal to 1.2 pounds.

Therefore, 550 grams is equal to 1.2 pounds, and it is the amount of flour needed.
