Answer:
40%
Step-by-step explanation:
Finley's pumpkin had a mass of 6.5 kg before he carved it.
After carving it, the pumpkin had a mass of 3.9 kg.
Now, we are asked to determine the % decrease in the mass of the pumpkin.
Therefore, the % decrease in mass is given by
%. (Answer)
I think it's E. The negative one property of multiplication. Each function is basically showing that multiplying/dividing two pluses makes a plus and multiplying/dividing one plus and one minus makes a minus etc!
Answer:
50 Swans or
100 Doves or
100 Hens
or
any combination that accomplish withthe following equation:
2x+y+z=100
where:
x: number of swans and x>0
y: number of doves and y>0
z: number of hens and z>0
Step-by-step explanation:
Part A.
What we can do to solve this problem is to assume that
the acceleration of Bryan is constant so that the velocity function is linear.
The standard form of a linear function is in the form:
y = m x + b
or in this case:
v = m t + b
where v is velocity and t is time, b is the y –intercept of
the equation
The slope m can be calculated by:
m = (v2 – v1) / (t2 – t1)
m = (12 – 15) / (7 – 4)
m = -1
Since slope is negative therefore this means the cyclist
are constantly decelerating. The equation then becomes:
v = - t + b
Now finding for b by plugging in any data pair:
15 = - (4) + b
b = 19
So the complete equation is:
v = - t + 19
This means that the initial velocity of the cyclists at t
= 0 is 19 km / h.
Part B. What we can do to graph the equation is to
calculate for the values of v from t = 0 to 12, then plot all these values in
the Cartesian plane then connect the dots.
Answer:
Step-by-step explanation:
we know that
In a parallelogram opposite sides are congruent
In this problem
we have that
AB and DC are opposite sides
AD and BC are opposite sides
so
AB=DC
AD=BC
step 1
Find the value of x
AB=DC
substitute the given values
solve for x
step 2
Find the length of AD
we have that
substitute the value of x
step 3
Find the length of BC
Remember that
AD=BC ----> by opposite sides
therefore
