<u>Answer:</u>

<h2>17</h2>

<u>Explanation:</u>

if ramin's house number = 3 yuza's

then choices are: n×3

1 , 3 | 2 , 6 | 3 , 9 | 4 , 12 | 5 , 13 | 6 , 18 | 7 , 21

since there are 13 house between yuza and ramin

thus it's 7 , 21 (because there's 13 numbers between 7 and 21)

yuza lives in house 7

ramin live in house 21

and since houses between yuza and glonti = 3 times houses between glonti and ramin, with a ratio of 3:1

13 - 1 = 12 (we subtracted 1 for glonti's house)

3:1 , 3+1=4

12/4=3

3×3=9

hence

9 and 3 are the numbers of houses in each side with glonti in the middle

9 houses - glonti's house - 3 houses

7 + 9 = 16 (yuza's house number 7 plus 9 houses ahead)

glonti lives in the house: 16 + 1 = 17

A diver went 25.65 feet below the surface of the ocean and then 16.5 feet further down he then rose 12.45 feet write and solve a

Anastaziya [24]

So a diver went 25.65 ft BELOW so it's negative.
then he went 16.5 ft further down, so that's negative also.
he then rose 12.45 ft, so that's positive.
so the expression is: -25.65+-16.5+12.45, the answer is 23.7

Felicia wants to build a kite with the shape shown. If AC is 60 cm, how many centimeters are in the length of BD?

Kay [80]

Answer:

Step-by-step explanation:

By applying tangent rule in the given right triangle AOB,

tan(30°) = $\frac{\text{Opposite side}}{\text{Adjacent side}}$

$\frac{1}{\sqrt{3}}=\frac{BO}{OA}$

$OA=BO(\sqrt{3})$

By applying tangent rule in the given right triangle BOC,

tan(60°) = $\frac{OC}{BO}$

OC = BO(√3)

OA + OC = AC

$BO(\sqrt{3})+BO(\sqrt{3}) =60$

2√3(BO) = 60

BO = 10√3

OC = BO(√3)

OC = (10√3)(√3)

OC = 30

By applying tangent rule in right triangle DOC,

tan(60°) = $\frac{OD}{OC}$

OD = OC(√3)

OD = 30√3

Since, BD = BO + OD

BD = 10√3 + 30√3

BD = 40√3

≈ 69.3

Five students are running for Junior class president. They draw straws to see who will go first, second, etc. In how many differ

SpyIntel [72]

<h3>Answer: 120</h3>

===================================================

Explanation:

There are 5 choices for the first selection, 4 choices for the second, etc etc until we reach 1 for the last selection. We have the countdown {5,4,3,2,1}. We'll multiply those values together to get our answer.

5*4*3*2*1 = 120

This operation of starting with some integer, counting down and multiplying along the way, is done so very often that it's given a name which is "factorial". The shorthand notation is to use an exclamation mark. So we'd say 5! = 120
