Step-by-step explanation:

if 1 inch equals 2.54 cm then 5ft will be:

=5*2.54

=12.7 cm

therefore, sara's height in centimeter:

=12.7+10

=22.7 cm

Some body can help me with a geometric mean maze
Mars2501 [29]

Answer:

See explanation

Step-by-step explanation:

Theorem 1: The length of the altitude to the hypotenuse of a right triangle is the geometric mean of the lengths of the segments of the hypotenuse.

Theorem 2: The length of each leg of a right triangle is the geometric mean of the length of the hypotenuse and the length of the segment of the hypotenuse adjacent to that leg.

1. Start point: By the 1st theorem,

x^2=25\cdot (49-25)=25\cdot 24=5^2\cdot 2^2\cdot 6\Rightarrow x=5\cdot 2\cdot \sqrt{6}=10\sqrt{6}.

2. South-East point from the Start: By the 2nd theorem,

x^2=40\cdot (40+5)=4\cdot 5\cdot 2\cdot 9\cdot 5\Rightarrow x=2\cdot 5\cdot 3\cdot \sqrt{2}=30\sqrt{2}.

3. West point from the previous: By the 2nd theorem,

x^2=(32-20)\cdot 32=4\cdot 3\cdot 16\cdot 2\Rightarrow x=2\cdot 4\cdot \sqrt{6}=8\sqrt{6}.

4. West point from the previous: By the 1st theorem,

9^2=x\cdot 15\Rightarrow x=\dfrac{81}{15}=\dfrac{27}{5}=5.4.

5. West point from the previous: By the 2nd theorem,

10^2=8\cdot (8+x)\Rightarrow 8+x=12.5,\ x=4.5.

6. North point from the previous: By the 1st theorem,

x^2=48\cdot 6=6\cdot 4\cdot 2\cdot 6\Rightarrow x=6\cdot 2\cdot \sqrt{2}=12\sqrt{2}.

7. East point from the previous: By the 2nd theorem,

x^2=22.5\cdot 30=225\cdot 3\Rightarrow x=15\sqrt{3}.

8. North point from the previous: By the 1st theorem,

x^2=7.5\cdot 36=270\Rightarrow x=3\sqrt{30}.

8. West point from the previous: By the 2nd theorem,

x^2=12.5\cdot (12.5+13.5)=12.5\cdot 26=25\cdot 13\Rightarrow x=5\sqrt{13}.

9. North point from the previous: By the 1st theorem,

12^2=x\cdot 30\Rightarrow x=\dfrac{144}{30}=4.8.

101. East point from the previous: By the 1st theorem,

6^2=1.6\cdot (x-1.6)\Rightarrow x-1.6=22.5,\ x=24.1.

11. East point from the previous: By the 2nd theorem,

20^2=32\cdot (32-x)\Rightarrow 32-x=12.5,\ x=19.5.

12. South-east point from the previous: By the 2nd theorem,

18^2=x\cdot 21.6\Rightarrow x=15.

13. North point=The end.

Nora and Lila are reading the same novel for book club.
stich3 [128]

Answer:

<u>1. Nora and Lila be on the same page of the book after 6 days and a half.</u>

<u>2. Nora and Lila be on the page 180.</u>

Step-by-step explanation:

1. Let's check the information given to resolve the question:

Current page of the novel that Nora is reading now = 128

Pages per day Nora reads = 8

Current page of the novel that Lila is reading now = 102

Pages per day Lila reads = 12

Days ahead for Nora and Lila will be on the same page = x

2. After how many days of reading will Nora and Lila be on the same page of the book?

128 + 8x = 102 + 12x

8x - 12x = 102 - 128 (Subtracting 12x and 128 at both sides)

-4x = -26

x = 6.5

<u>Nora and Lila be on the same page of the book after 6 days and a half.</u>

<u>3.</u> What page will they be on?

Nora : 128 + 8 (6.5) = 128 + 52 = 180

Lila : 102 + 12 (6.5) = 102 + 78 = 180

<u>Nora and Lila be on the page 180</u>
