Answer:

9 boys and 12 girls

Step-by-step explanation:

if you multiply the denominators by 3, you get "out of" 21. All you need to do after that is multiply the top by 3 as well and it tells you there are 9 boys and 12 girls.

Find the hypotenuse of a right triangle that has a 13cm leg and a height of 7cm
12345 [234]

Answer:

14.76 cm

Step-by-step explanation:

Use the pythagorean theorem:

a² + b² = c²

Plug in the side lengths and solve for c:

7² + 13² = c²

49 + 169 = c²

218 = c²

14.76 = c

So, the hypotenuse is approximately 14.76 cm

Which linear function has the steepest slope?
miskamm [114]

Answer: The correct option is A.

Explanation:

The slope intercept form is,

y=mx+c

Where m is slope.

The point slope form is,

y-y_1=m(x-x_1)

Where m is slope.

On Comparing the first equation with slope intercept form, we get m = -8.

On Comparing the second equation with point slope form, we get m = -2.

On Comparing the third equation with slope intercept form, we get m = 7.

On Comparing the Fourth equation with point slope form, we get m = 6.

The steepest line have greatest absolute slope value.

Since the equation 1 has greatest absolute slope value,i.e., 8 therefore option A is correct.
