Answer:

B

Step-by-step explanation:

The chances of the first student walking to school is 7/30.

Without replacement, there are 29 students left. Hence the chance of the second student walking to school is 6/29 of the original 7/30 chance.

(\frac{7}{30} )(\frac{6}{29} )=\frac{7}{145}

Answer:

666.6667 feet²

Step-by-step explanation:

So.

Since the scale is 1 : 20, we can do 4 x 20 and 5 x 20, Which is 80 and 100.

Find area: 80 x 100 = 8000 we can just add 2 zeros to 80 since it's multiplying by 100.

So it's 8000in²

Then we do 8000 in to feet.

Which is ≈ 666.6667feet

btw it asked for feet so we give them FEET

katovenus [111]

Answer:

a=\sqrt\frac{120}{13}

b=\frac{-7}{4}\sqrt \frac{120}{13}

Step-by-step explanation:

Let the larger number is a and the smaller number is b.

According to the question,

a² + b² = 100 .... (1)

And

a² = a (4b + 8a)

a = 4b + 8a

b = -7a/4    ..... (2)

Put in equation (1)

a^{2}+\left ( \frac{-7a}{4} \right )^{2}=100

65a² = 100 x 16

a^{2}=\frac{600}{65}

a=\sqrt\frac{120}{13}

Put in equation (2)

b=\frac{-7}{4}\sqrt \frac{120}{13}
