There are a total of 20,000 available numbers. To ascertain how many phone numbers are available, the number of digits in each number must be known. Here, I will assume each number has 7 digits. This leads to the format starting with either 373XXXX or 377XXXX, where each X can be any digit from 0 to 9. This results in 10 options for each X. Therefore, there are 10×10×10×10 = 10,000 distinct phone numbers starting with 373 and another 10,000 with 377, totaling 20,000 numbers.

The equation T^2 = A^3 shows the relationship between a planet’s orbital period, T, and the planet’s mean distance from the sun,
PIT_PIT [12445]

Let's denote the orbital period of planet X as T and its average distance from the sun as A. For planet Y, let its orbital period be T_1, implying that if planet Y's mean distance from the sun is twice that of planet X:

Z^2=(2A)^3\\ Z^2=8A^3\implies\\ Z^2=8T^2 \implies\\ Z=2\sqrt{2}T

This indicates that the orbital period for planet Y increases by a factor of 2\sqrt{2}

Dan gets pic 'n mix when at the cinema and makes his bag up with 3 types of sweet. He picks 3 times as many cola bottles as smar
Leona [12618]

Response:

1/6

Detailed explanation:

Let

c -----> the count of cola bottles chosen by Dan

s -----> the count of smarties selected by Dan

m -----> the count of marshmallows selected by Dan

we have

c=3s -----> A equation

m=2s -----> B equation

we understand that

To determine the fraction of the sweet bag that consists of smarties, we must divide the number of smarties by the total amount of sweets

The overall number of sweets is calculated as

(c+s+m)

substituting equations A and B into the total sweets

(3s+s+2s) =6s

Calculate the fraction

s/6s

Reduce it

1/6

A game spinner has regions that are numbered 1 through 8. If the spinner is used twice, what is the probability that the first n
Zina [12379]
Let P(3) denote the probability of landing on 3 in a spin, and P(5) denote the probability of landing on 5. In probability terms, "AND" signifies multiplication while "OR" indicates addition. We aim to find the probability that the first number is "3" AND the second number is "5." Thus, we identify the individual probabilities and MULTIPLY them. The spinner has numbers ranging from 1 to 8, each appearing once. Therefore, since there is one instance of "3," we have P(3) = 1/8 and similarly P(5) = 1/8. Consequently, the overall probability of P(3 and 5) is 1/8 multiplied by 1/8, which equals 1/64.
