parallelogram, quadrilateral

Step-by-step explanation:

a rectangle is a quadrilateral because it has 4 sides.

an earthquake measures 3.6 on the richter scale. what is the amount of energy (ergs) released by the earthquake? give an exact a

Alisiya [41]

We have that

log10 E = 4.4 + 1.5M
E=the released energy in Joules (J)
M= earthquake measures---------- > 3.6
log10 E = 4.4 + 1.5*3.6
log10 E = 9.8----------> E=10^(9.8)= 6.309573444 x10^9 J

the answer is 6.309573444 x10^9 J

Two number cubes are rolled. What is the probability that the sum of the numbers rolled is either 3 or 9?. A.1/6. B.1/13. C.1/18

Elis [28]

So 6 times 6 is 36 so 36 possibilities and the number that add up to 3 or nine are (2,1; 3,6; 4,5;) so 3 out of 36 or 1 out of 12, the answer is not there

Total payment:

40*6= £240

Teacher earns in total per given week:

240*90/100 = £216

What values of a and b make the equation true? sqrt(648)=sqrt(2^a•3^b)

Anuta_ua [19.1K]

ANSWER

The value of a and b are:

$a=3,b=4$

EXPLANATION

The expression given to us is

$\sqrt{648} = \sqrt{ {2}^{a} \times {3}^{b} }$

We square both sides of the equation to obtain

$648= {2}^{a} \times {3}^{b}$

We now find the prime factorization of 648 to obtain,

${2}^{3} \times {3}^{4} = {2}^{a} \times {3}^{b}$

We now compare the exponents on both sides of the equation to obtain,

$a=3,b=4$

Therefore the correct option is C
