Answer:
a) 32100 millimeters
c) 3,210 centimeters
d)3.21 decameters
Step-by-step explanation:
To find which measurements are equal 321 decimeters, we will follow the steps below:
<u>changing 321 decimeters to millimeters</u>
let x be 321 decimeters in millimeters
1 decimeter = 100 millimeters
321 decimeters = x
cross - multiply
x = 321× 100
x = 32100 millimeters
hence, 321 decimeters = 32100 millimeters
<u>converting 321 decimeters to centimeters</u>
let y be 321 decimeters in centimeters
1 decimeters = 10 centimeters
321 decimeters = y
cross-multiply
y = 321× 10
y = 3210 centimeters
Thus, 321 decimeters = 3210 centimeters
<u>converting decimeter to decameters</u>
let z represent 321 decimeters in decameters
1 decameter = 100 decimeter
z = 321 decimeter
cross-multiply
100 z = 321
divide both-side by 100
100z/100 = 321/100
z=3.21 decameters
therefore, 321 decimeters = 3.21 decameters
Im not sure wym but i think the answer is 20

Answer:
$647.99
Step-by-step explanation:
Divide the tax rate (9.750%) by 100 to get a decimal rate of 0.09750.
Add 1 to the decimal rate to get 1.09750.
Divide that tax-included price ($647.99) by 1.09750 price to get a pretax price of $590.42.
Subtract the pretax price from $647.99 to get the sales tax amount of $57.57.
Answer:
Now despite what you may believe, 1:3 is not 1/3 in this situation. In this case, it means "1 equal part to 3 equal parts", which is a total of 4 equal parts. In short, this question is to place point P 1/4 the distance from A to B.
Firstly, how far apart is -1 from 7 (the x-coordinates)? That would be 8 units. Multiply 1/4 by 8:
Next, how far apart is 2 from 8 (the y-coordinates)? That would be 6 units. Multiply 1/4 by 6:
Next, since from -1 to 7 you are increasing, add 2 to -1:
1 is your x-coordinate
Next, since from 2 to 8 you are increasing, add 3/2 to 2:
7/2 is your y-coordinate.
Putting it together, your answer is A. (1, 7/2)
