Answer: See explanation

Step-by-step explanation:

67 × 100 = 6700

67 × (10 x 10) Yes

10 × 10 = 100

67 × 100 = 6700

67 × (10 × 10 × 10) No

10 × 10 × 10 = 1000

67 × 1000 = 67000

670 × 10³ No

10³ = 1000

670 × 1000 = 670000

670 No

670 ≠ 6700

6700 Yes

6700 = 6700

67000 No

67000 ≠ 6700

Hope this helped!

Answer:

Step-by-step explanation:

Given that the owner of a motel has 2900 m of fencing and wants to enclose a rectangular plot of land that borders a straight highway.

Fencing is used for 2times length and 1 width if highway side is taken as width

So we have 2l+w = 2900

Or w = 2900-2l

Area of the rectangular region = lw

$A(l) = l(2900-2l) = 2900l-2l^2\\$

Use derivative test to find the maximum

$A'(l) = 2900-4l\\A"(l) = -4$

So maximum when I derivative =0

i.e when $l =\frac{2900}{4} =725$

Largest area = A(725)

= $725(2900-2*725)\\= 1051250$

1051250 sqm is area maximum

Help anyone?? Not that hardd no links ! :(

Ivanshal [37]

Answer:

1.2

Step-by-step explanation:

First, you cancel out $\frac{6}{20}$ to become $\frac{3}{10}$

Then that becomes $-\frac{3}{10}+1.5$

Now, you convert the element to a decimal form to be $-0.3+1.5$

Finally, you subtract them (because a negative plus a positive is subtraction) to get the final answer of 1.2

Hope this helps!
