Answer:

-62

Step-by-step explanation:

y³ – 2y (y – 5) + 13

when y = -3

y³ – 2y (y – 5) + 13

=(-3)³ – 2(-3) [ (-3) – 5] + 13 (by PEDMAS, evaluate parentheses first)

=(-27) + (6) (-8) + 13 (next do multiplication)

=(-27) + (-48) + 13

= -27 - 48 + 13

= -62

A model of a submarine has a length of 6.6 meters. Use the scale 1:35 to find the length

kirill115 [55]

The scale 1:35 indicates that for every 1 meter on the scale model, there are really 35 meters in real life.

So if the scale model is 6.6 meters, you would do 35 * 6.6 to find the length in real life, which is 231 meters.

The answer is 231 meters.

A plot of land has an area of 1,089,000 square feet.The conversion factors between different area measures are shown below.27,87

IgorC [24]

Part A) 24.79 acres

1) Since that plot has an area of

$1,089,000ft^2=1.08\times10^6ft^2$

And the number of units must be between 10 and 10² units.

Part A)

$\begin{gathered} 27,878,400ft^2=2.78784\times10^7ft^2=1m^2 \\ 43560ft^2\text{ =4.356 }\times10^4ft^2\text{ = 1 acre} \end{gathered}$

2) Let's convert them to the apparently plausible units, see if it fits within the given interval.

$\begin{gathered} \frac{1.08\times10^6}{4.356\times10^4}=24.79\text{ acres} \\ \frac{1.08\times10^6}{2.78784\times10^7}=0.03m^{2} \end{gathered}$

We can see that 0.03 m² does not belong to the given interval.

3) Hence, the answer is 24.79 acres.
