Helen's house is located on a rectangular lot that is 1 1/8 miles by 9/10. Estimate the distance around the lot.

1 answer:

7 0

You round 1 1/8 to 1 and 9/10 to 1 (since you are estimating) and then you add 1+1+1+1, which is 4 because to find perimeter you add the lengths and the widths together.

What is the scale factor, perimeter ratio, surface ratio, and the volume ratio?????????????????????????????

tamaranim1 [39]

Answer:

Scale factor = $\frac{4}{9}$

Perimeter ratio = 4 : 9

Surface area ratio = 16 : 81

Volume ratio = 64 : 729

Step-by-step explanation:

Volume ratio = $\frac{\text{volume of small prism}}{\text{Volume of large prism}}$

= $\frac{128}{1458}$

= $\frac{64}{729}$

= 64 : 729

Scale factor = $\sqrt[3]{\frac{\text{volume of small prism}}{\text{Volume of large prism}}}$

= $\sqrt[3]{\frac{64}{729}}$

= $\frac{4}{9}$

Perimeter ratio = Scale factor

= $\frac{4}{9}$

= 4 : 9

Surface area ratio = (Scale factor)²

= $(\frac{4}{9})^{2}$

= $\frac{16}{81}$

= 16 : 81

Factor 27a^3 b^9+8c^18

Artemon [7]

Answer:

(3ab^3+2c^6)(9a^2b^6-6ab^3c^6+4c^12)

Step-by-step explanation:

Given:

Polynomial 27a^3 b^9+8c^18

Factoring the given polynomial

27a^3b^9 can be written as

=3^3.a^3.b^3^3

=(3ab^3)^3

Also 8c^18 can be written as

=2^3.c^6^3

=(2c^6)^3

Hence Polynomial 27a^3 b^9+8c^18 can be written as

=(3ab^3)^3+(2c^6)^3

Applying sum of cubes formula i.e. a^3 + b^3=(a+b)(a^2 – ab + b^2)

=(3ab^3+2c^6)(9a^2b^6-6ab^3c^6+4c^12) !
