Answer:

The first option is correct: Angle 2 through 5

Step-by-step explanation:

Both angles 2 and 5 are directly vertical or opposite to each other and are the only angles that are proportionate/equal sizes.

The other three options are incorrect because angles 4 and 3 are not the same equal value and are right next to each other making them not vertically across.

angles 1 and 5 are close to being vertical but are not the same size as angle 1 is much smaller than angle 5.

angles 6 and 1 are next to each other making them not vertically to each other and angle 6 is much larger than angle 1.

the correct answer is angles 2 and 5, the first option.

The area of the rect. is 100 ft times 64 ft, or 6400 ft^2.

Let's list factors of 6400: 64,100

64= 2^6

100= 2^2*5^2

Here we see that 2 appears 8 times as a factor, and 5 appears 2 times:

6400 = 2^6 * 10^2 = 2^8*5^2

When a constant force acts upon an object, the acceleration of the object varies inversely with its mass. When a certain constan

Answer:

$a = 6m/s^2$

Step-by-step explanation:

Given

When mass = 4kg; Acceleration = 15m/s²

Required

Determine the acceleration when mass = 10kg, provided force is constant;

Represent mass with m and acceleration with a

The question says there's an inverse variation between acceleration and mass; This is represented as thus;

$a\ \alpha\ \frac{1}{m}$

Convert variation to equality

$a = \frac{F}{m}$ ; Where F is the constant of variation (Force)

Make F the subject of formula;

$F = ma$

When mass = 4kg; Acceleration = 15m/s²

$F = 4 * 15$

$F = 60N$

When mass = 10kg; Substitute 60 for Force

$F = ma$

$60 = 10 * a$

$60 = 10a$

Divide both sides by 10

$\frac{60}{10} = \frac{10a}{10}$

$a = 6m/s^2$

<em>Hence, the acceleration is </em> $a = 6m/s^2$ <em />
