Step-by-step explanation:
EDGE
Rate is the change in one variable in relation to another variable. Generally, rate is calculated as follows:
R = ΔV1/ΔV2
Where
R = Rate
ΔV1 = Change in variable 1
ΔV2 = Change in variable 2
In the current scenario,
ΔV1 = 250,000 m^3 of mulch applied
ΔV2 = 1 m^2 of garden space
Therefore,
Rate of applying much is, R = 250,000/1 = 250,000 m^3/m^2
Answer:
Option (D)
Step-by-step explanation:
Standard equation of a quadratic function is,
ax² + bx + c
Comparing this function with the given quadratic function,
f(x) = 2x² - 4x - 3
a = 2, b = -4 and c = -3
By using quadratic formula to get the value of x,
x = 
= 
= 
= 
= 
Therefore, Susie made a mistake in step IV.
Option (D) is the answer.
Answer:
Dale invested in fund B $8,000
Step-by-step explanation:
We can arrange the given information into the nex equation:
4000*5% + x*2% = (4000+x)*3%
4000*0.05 + 0.02x = 4000*0.03 + 0.03x
200 + 0.02x = 120 + 0.03x
200 - 120 = 0.03x - 0.02x
80 = 0.01x
x = 80/0.01
x = 8,000 He invested in fund B.
Step-by-step explanation:
let George money will be X and Albert be Y
30$+x=y
x-50$=5y
30+x=y
x=y-30
(y-30)-50=5y
y-80=5y
y-5y=80
-4y=80
y=-20
x=-50
