Answer:

510 ft^2

Step-by-step explanation:

(12*9)+(12*9)+(7*9)+(7*9)+(7*12)+(7*12) = 108+108+63+63+84+84 = 510 ft^2

Hope this helped! :)

A graduated cylinder with 10.0 mL of water ha mass of 25.0 g. 51 paper clips are added to the graduated cylinder . The total mas

Tatiana [17]

Answer: The density of the paper clips is 0.64 g/ml.

Step-by-step explanation:

Given : Volume of water = 10.0 mL

mass of water = 25.0 g

After 51 clips added to water , the total mass = 28 g

Total volume = 14.7

Mass of clips = total mass - mass of water

= 28 g-25g = 3g

Volume of clips = Total volume- Volume of water

= 14.7- 10.0 = 4.7 ml

Density of paper clips = $\dfrac{\text{Mass of paper clips}}{\text{Volume of paper clips}}$

$=\dfrac{3}{4.7}=0.638297\approx0.64\ g/ml$

Hence, the density of the paper clips is 0.64 g/ml.

Which table will have the greatest value of y when x = 7?

kow [346]

Answer:

(a) (x, y) = (7, 147)

Step-by-step explanation:

Table A represents a quadratic function: y = 3x², so for x=7, y = 3·7² = 147.

Table B represents a linear function: y = 12x +2, so for x=7, y = 86.

Table C represents an exponential function: y = 2^x, so for x=7, y = 128.

Table D represents a linear function: y = 10x +2, so for x=7, y = 72.

The greatest value of y for x=7 will be found in Table A.

_____

Table a's values go down and up, with symmetry about x=0. This suggests a quadratic function. A plain y=x² function will have the value 1 at x=1. This one has the value 3, so looks like y = 3x². Checking values for x=2 and x=3 confirms this.

Table b's values go consistently up, with a difference of 12 each time. The value for x=0 is 2, so we know this linear function has equation y=12x+2.

Table c's values double from one value of x to the next, so the function is exponential with a base of 2. The multiplier is 1, the value for x=0, so the equation is y = 1·2^x.

Table d is similar to table b, except the common difference is 10 instead of 12. So, the slope in slope-intercept form is 10 instead of 12: y = 10x + 2.
