They want you to write the number in index form.

The number is 5N^2, where N = 3 x 5^2 x x^3

So:

5N^2 = 5 x (3 x 5^2 x x^3)^2

= 5 x (3^2 x 5^4 x x^6)

= 3^2 x 5^5 x x^6

or a bit neater looking: 3² ₓ 5⁵ ₓ x⁶

The ratio of boys to girls in a class is 4:5 what fraction of the class is boys and what fraction of the class is girls

ale4655 [162]

First, let's start off with the information we already have. Since the ratio is 4 boys to 5 girls, there has to be a minimum of 9 students (4 being boys and 5 being girls).

9 will be the denominator of both of our fractions since the boys and girls are in the same class.

The fraction of boys in the class is 4/9 (since there are 4 boys to 5 girls in a class of 9, we would write 4 over 9) and the fraction of girls in the class is 5/9.

This is a simplified version of the fractions. If this is a multiple-answer question and 4/9 and 5/9 are not up there, try multiplying the fractions with different numbers and see what fractions will be correct.

But either way, 4/9 and 5/9 are correct :)

Answer:

parallel:

$7x - 8y = 60$

perpendicular:

$8x + 7y = 4$

Step-by-step explanation:

original line:

-7x + 8y = 4

m = 7/8

parallel:

m = 7/8

L: 7x - 8y = k

(4, -4) -> L

28 + 32 = 60 = k

L: 7x - 8y = 60

perpendicular:

m = -8/7

L: -8x + 7y = k

(4, -4) -> L

-32 + 28 = -4 = k

L: -8x -7y = -4

=> 8x + 7y = 4

Justin is marking a border for a garden. He walks 200 feet to the east, then turns and

ELEN [110]

Answer:

d = 233.23 feet

Step-by-step explanation:

Given that,

Justin walks 200 feet to the east, then turns and walks 120 feet due south.

We need to find the total distance walked by Justin. Let the distance be d.

We can use the Pythagoras theorem to find it such that,

$d=\sqrt{d_1^2+d_2^2} \\\\d=\sqrt{200^2+120^2} \\\\d=233.24\ feet$

So, he walk 233.23 feet in all.
