Answer:
70 joules
Step-by-step explanation:
We have the following information
100N and 0.7 m
What is workdone?
We say that Work is done if a force which is applied to an object is able to move that object. We calculate the value of The work by multiplying the force by what is known to be the movement of the object.
(Workdone = Force x distance).
A force of 100 newtons, in this question moves an object 0.7 meters
Workdone =
100N x 0.7
= 70 joules
Thank you!
Answer:
44200 of them were girls
Step-by-step explanation:
If the ratio is 8:25, we must find x:65000
In order to change the ratio 8:25 into x:65000, we must multiply 25 by 2600. So you have to multiply 8 by 2600 too
8 x 2600 = 20800
65000 (total students) - 20800 (boy students) = 44200 (girl students)
#6
Yes
Direct variation because Time increases cupcakes increases and vice versa
#B
Constant of proportionality represents the amount of time required per cupcakes
#7
Yes we can find it
We have to check the x and y values of the ordered pairs (x,y)
If y is decreasing with respect to increase in x then it's inverse variation
Answer:
70 students
Step-by-step explanation:
If 40% of all students in Mrs. Well's class got an A, and 28 students got an A, that means that 28 = 40%
To find the total number of students, we need to find 100%
40% = 28
Divide by 4
10% = 7
Multiply by 10
100% = 70
So there are 70 students in Mrs. Well's class.
Hope this helps you! :D
