A. Expanding the given expression, you have
balance = 75r^2 +150r +75
B. For r=0.10, the balance after 2 years is 75*1.1^2 = 90.75
C. The difference between $120 and 90.75 is $29.25. You need $29.25 more to buy the bicycle.
The slope for this problem is -3
Answer:
The midpoint of TS is (-1,-3)
The coordinates of M should be (8,18)
Step-by-step explanation:
Answer: 364 m squared
Step-by-step explanation:
to find the surface area of a rectangular prism, you must do width*length + hight*length + height*width
Answer:
33%
Step-by-step explanation:
Assuming the weight of the mixture to be 100g**, then the weight of ryegrass in the mixture would be 30g.
Also, assume the weight mixture X used in the mixture is Xg, then the weight of mixture Y used in the mixture would be (100-X)g.
So we can now equate the parts of the ryegrass in the mixture as:
0.4X + 0.25(100-X) = 30
<=> 0.4X + 25 - 0.25X = 30
<=> 0.15X = 5
<=> X = 5/0.15 = 500/15 = 100/3
So the weight of mixture X as a percentage of the weight of the mixture
= (weight of X/weight of mixture) * 100%
= (100/3)/100 * 100%
= 33%
