Answer:

Below in bold.

Step-by-step explanation:

The smaller one has side 2 and the corresponding side on the larger one is 5, so the answer is 2/5.

The individual sides and perimeter are one-dimensional, so:

The ratio of their perimeters is the same 2/5.

The ratio of their areas ( which is 2 dimensional) is 2^2/5^2 = 4/25.

The angle of elavation would be 45°, this is because straight up would be represented by 180°, and 90°, would remain as 1200 ft traveled, and half of 90°, is 45° which would double the distance traveled

What is the solution to StartFraction h over negative 24 EndFraction less-than-or-equal-to 18?

attashe74 [19]

Answer:

h greater-than-or-equal-to negative 432

Step-by-step explanation:

$\frac{h}{-24} \leq 18$

* multiply each side by -24 *

$\frac{h}{-24} *-24=h\\-24*18=-432$

IMPORTANT NOTE: when multiplying an inequality by a negative number you must flip the sign. So if the inequality sign was once facing the constant ( 18 ) then it will flip and face the variable ( h )

Thus,

h ≥-432

Which can also be expressed as h is greater than or equal to negative 432

Extra notes: You only have to flip the inequality sign if it's being multiplied by a negative number. Meaning if its multiplied by a positive number then the inequality sign does not flip.

Answer:

5. A.

6. F

Step-by-step explanation:

5. Perpendicular lines have slopes that are negative reciprocals of one another, so slope is 3

y = 3x + b

using coordinates (-6,3)

3 = 3(-6) + b

b = 21

y = 3x + 21

6. I think F is the right answer
