Answer:
$4,027.51
Step-by-step explanation:
Use the formula P*e^(r * t)
P = principal amount
e = the constant e
r = rate
t = time, in years
2,000 * e ^ (0.07 * 10)
2,000 * e ^ (0.7) ≈ 4,027.51
Answer:
$6.25 marked up 25% is $7.81
Step-by-step explanation:
First, you have to find what 25% is of 6.25.
Step 1: Our output value is 25.
Step 2: We represent the unknown value with x.
Step 3: From step 1 above, 25=100%.
Step 4: Similarly, x=6.25%.
Step 5: This results in a pair of simple equations:
25=100%(1)
x=6.25%(2)
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
<u>25 </u> = <u>100</u>
x 6.25
Step 7: Again, the reciprocal of both sides gives
<u> x </u> = <u>6.25</u>
25 100
x= 1.5625
x≈ 1.56
Once you've known what 25% is, you add it to 6.25.
1.56+6.25= 7.81
Answer:
Step-by-step explanation:
- Milk of Holstein cows ⇒ 3.66% butterfat
- Milk of Jersey cows ⇒ 4.5% butterfat
<u>If we add x gal of 4.5% milk, then we have below equation:</u>
- 100*0.0366 + x*0.045 = (100 + x)*0.04
- 3.66 + 0.045x = 0.04x + 4
- 0.045x - 0.04x = 4 - 3.66
- 0.005x = 0.34
- x = 0.34/0.005
- x = 68 gal
Trapezoid Area = (Bases / 2) * Height
20 cm² = 5 * Height
Height = 4 cm
