WILL GIVE BRAINLIEST! What is the constant of proportionality between cups of rice and cups of water shown in this table?

Mathematics

algol [13]3 years ago

Answer:

E (none of the above)

Step-by-step explanation:

1 = k(1.5)

2 = k(3)

Therefore, k = 2/3

and when we put k = 2/3 into all values in the table we notice it is right

but it could be "A" also if the relationship was cups of water to cups of rice

A clock is constructed so that it keeps perfect time when its simple pendulum has a period of 1.000 s at locations where g 5 9.8

mafiozo [28]

Answer

Given,

Period of the Pendulum, T= 1 s

acceleration due to gravity, g = 9.8 m/s²

Length of Bob = 0.2482 m

Loss of time in the clock = 1.5 minutes/ day

Loss of time in 1 oscillation

= $\dfrac{1.5\times 60}{24\times 60\times 60}$

= 0.001042

Hence, time period, T = 1 + 0.001042

T = 1.001042 s

a) Using Time period of oscillation formula

$T = 2\pi \sqrt{\dfrac{L}{g}}$

$1.001402 = 2\pi \sqrt{\dfrac{0.2482}{g'}}$

$g' = 9.77\ m/s^2$

Free fall acceleration at the clock location = 9.77 m/s²

b) Length of pendulum bob to keep it perfect time

$1 = 2\pi \sqrt{\dfrac{L}{g}}$

$1 = 2\pi \sqrt{\dfrac{L'}{9.77}}$

$L' = 0.2475\ m$

Hence, Length of pendulum bob is equal to 0.2475 m.

10) A rhombus has a<br> diagonal 8.6 mm long<br> and an area of 81.7 mm. what is the<br> perimeter?

BaLLatris [955]

Answer:

P=41.72

Step-by-step explanation:

S=ACxDB/2

81.7=8.6xDB/2

81.7=4.3xDB|:4.3

19(mm)=DB

DO=19/2=9.5

OC=8.6/2=4.3

(O is the center of the rhombus, where two diagonals meet)

a²+b²=c² (DO²+OC²=DC²)

9.5²+4.3²=c²

90.25+18,49=c²

√108,74=√c²

c≈10.43

P=4c

P=4x10.43

P=41.72

Hope it helps:)
