Use the formula F = ma, where F is the applied force, m is the mass and a is the acceleration:
7 m
F = (45 kg)(----------- = 315 N, where N represents the metric unit of force
sec^2
Let's say that s=spoons and f=forks.
According to this, we can say that:
{4s+3f=15
{4s+f=13
This is a system.
We can then use elimination to solve and isolate the variable:
(4s-3f=15)
- (4s+f=13)
We can then subtract and conclude that:
-4f=2
-f=1/2
f=-1/2
Answer:
3 3/16
Step-by-step explanation:
Conversion a mixed number 8 1/2
to a improper fraction: 8 1/2=8×2+1/2=16+1/2=17/2
To find a new numerator:
a) Multiply the whole number 2 by the denominator 3. Whole number 2 equally 2×3/3= 6/
3
b) Add the answer from previous step 6 to the numerator 2. New numerator is 6 + 2 = 8
c) Write a previous answer (new numerator 8) over the denominator 3.
Two and two thirds is eight thirds
Divide: 17/2×8/3=17/2×3/8=17×3/2×8= 51/
16
Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 8/3 is 3/8) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. In the following intermediate step, it cannot further simplify the fraction result by canceling.
In other words - seventeen halves divided by eight thirds = fifty-one sixteenths.

Answer:
(1)
And for this case we know the following condition "The length of the field is 7 yards less than quadruple the width" and we can write this :
And replacing into equation (1) we got:
Adding 14 in both sides we got:
And dividing 10 on both sides we got:
And then we can solve for X and we got:
Step-by-step explanation:
For this case we can set up the following notation:
X represent the lenght
Y represent the width
And since we have a rectangular playing filed the perimeter is given by:
(1)
And for this case we know the following condition "The length of the field is 7 yards less than quadruple the width" and we can write this :
And replacing into equation (1) we got:
Adding 14 in both sides we got:
And dividing 10 on both sides we got:
And then we can solve for X and we got:
