7/8
U do one and one half plus one fourth
Then get that answer and divide it by 2
You then get 7/8
Btw u divide by 2 in orer to find half of the recipe
Answer:
m=-3
x1,y1=1,-5
we have,
y-y1=m(x-x1)
y-(-5)=-3(x-1)
y+5=-3x+3
3x+y+2=0 is the required eqn
Answer:
- A(0) = 2; A'(t) = 6 - 0.08A(t)
- A(∞) = 75
Step-by-step explanation:
The initial value is said to be 2 pounds, so A(0) = 2.
__
The influx is (1.5 #/gal)×(4 gal/min) = 6.0 #/min.
The outflow is (4 gal)/(50 gal) × A(t) = 0.08A(t).
The rate of change of A(t) is then ...
A'(t) = 6 - 0.08A(t)
__
When the system reaches steady state, A'(t) = 0, so ...
0 = 6 - 0.08A(∞)
A(∞) = 6/0.08 = 75
75 pounds of salt will be in the tank after a long period.
Answer:
C. 301
Step-by-step explanation:
Since the store marked up the price by 115%. You need to first find what is 100% of 140 and then 15% of 140. 100% of 140 is obviously 140. To find 15% of 140, you take 10%, which is 14, then add half of that which is 7 to 14. 15% of 140 is 21. So you add 140 and 21; it gives you 161, which is 115% of 140. Once you add 161 to 140, it gives you a total of 301.
Answer:
<em>Choice C is correct because -4 + 4 = 0 as required.</em>
Step-by-step explanation:
<u>Addition and Subtraction</u>
The number line shown in the image indicates the integer +4.
We need to find a number that added to 4 results in 0.
Choice A is not correct because 4 + 4 = 8
Choice B is not correct because -1/4 + 4 = 15/4
Choice C is correct because -4 + 4 = 0 as required.
Choice D is not correct because 1/4 + 4 = 17/4
