Answer:

60 D's

Step-by-step explanation:

We are given that the ratio of D to A is 4 to 72,

We can write that as 4:72.

Since students got 1080 A's. we can divide 1080 by 72 to help us find the answer.

1080/72=15

We know that the relationship between the amount of D's simplified and the actual amount of D's is equal to 15 times. So we do the given amount (4) multiplied by 15 (4*15) to get 60.

Please let me know if you have any questions.

What is the equation of the line that passes through the point (4,7) and has a slope of o?

Svetlanka [38]

Answer:

The equation of the line that passes through the point (4,7) and has a slope of 0 will be:

$y=7$

Step-by-step explanation:

As we know the equation of a line in a slope-intercept form of an equation is

$y = mx + b$

Here,

m is the slop

b is the y-intercept

substituting the point (4,7) and slope m=0

$y = mx + b$

$7=0(4)+b$

$7=0+b$

$b=7$

Therefore, the equation of the line that passes through the point (4,7) and has a slope of 0 will be:

$y = mx + b$

$y=0x+7$

$y=7$

The potential energy of an object varies jointly with the mass of the object and the height of the object off the ground. A 25-k

xxMikexx [17]

Answer:

This is physics. By the way look the explanation.

Step-by-step explanation:

The formula of Potential Energy is E=mgh, where m is the mass of the object, g the gravitational, and h the height of the object. Given that the potential energy of the object is 150 Joules at 3 meters height, Represent m=E/(g*h), considering g=9.8 m/s^2(Because this value was used for the first object), we get m=150/9.8/3=5.102
