Answer:
Absolute: 39 pounds
Relative: 6.5%
Step-by-step explanation:
To find the absolute difference, we simply have to see by how much pounds the estimation was off.
The real measure was 639 pounds, the estimated weight was 600.
D = 639 - 600 = 39 pounds.
For the percent of error, we divide the absolute difference (39) by the real value (639) and we'll get the % of error. So,
%D = 39 / 600 = 0.0610, so 6.1%
We don't need to round it to the nearest tenth, since it's already to that precision level.
21.6 meters per hour
Solve by dividing 54 by 2.5
Answer:
66000
Step-by-step explanation:
since the graph represents a proprtional relationship the equation of the graph must be written this way :
y = ax where a is the slope
you can notice that 2 goes with 24000
so 24000 = 2a then x = 24000/2= 12000
so a = 12000
now replace x with 5.5
y= 5.5*12000=66000
Answer with explanation:
It is given that, G C F of two polynomials is 5 z.
We have to Write that two polynomials.
A=5 z² + 5 z =5× z× (z+1)
B=10 z + 5 z²=5×z×(z+2)
→→G C F ,of A and B=5 z
Now, writing polynomials in equivalent form
1.5 z² + 5 z =5× z× (z+1)=(z+1)×z×5=5 z + z²
2. 10 z + 5 z²=5×z×(z+2)=(z+2)×z×5=5 z² + 10 z
to write in equivalent form of above polynomials, we have used commutative property of addition ,and Multiplication ,which states that, A+B=B +A, and AB=BA.
And, Distributive property of multiplication with respect to addition and Subtraction.
1. A × (B +C)=A × B + A × C
2. A × (B -C)=A × B - A × C
Answer:
(3)
Replcaing equation (3) into equation (2) we got:
And solving for Y we got:
And solving for X from equation (3) we got:
So we need 3L of orange juice with 25% of concentration and 17 L of orange juice with 5% of concentration
Step-by-step explanation:
For this problem we can work with the concentration of water and orange juice.
Let X the amount for the orange juice with 25% content and Y the amount for the orange juice with 5% of content
Using the concentration of orange juice we have:
(1)
And for the water we have:
(2)
If we solve for X from equation (1) we got:
(3)
Replcaing equation (3) into equation (2) we got:
And solving for Y we got:
And solving for X from equation (3) we got:
So we need 3L of orange juice with 25% of concentration and 17 L of orange juice with 5% of concentration
