Page 2 Answer: 175
Page 3 Answer: Alicia used 1.5 gallons to travel a distance of 37.5 miles.
Page 4 Answer: I think its 117 but I could be wrong...
Step-by-step explanation:
Page 1:
We just simplify
by dividing and get 9/5
Page 2: Since they want to DOUBLE her amount in her savings, we double her current amount (125) and get 250 by adding.
Next, we subtract 125 from 300 in her checking and get 175.
Page 3:
We use the titles so solve the graph.
Step-by-step explanation:
Area if the rectangular pool= 10m×7m×8m
= 560m³
3/4 of 560m³
3/4×560
= 420
Hence , the water occupies 420m³ place
To do this you first have to set this up vertically.
First you multiply through with the 2 (44×2=88). Then next, you have to multiply through with the 1 (44×1=44) But since this is the second line, you have to add the 0 to the end (440).
Now you simply add 88+440=528.
Answer:
yields 2 real roots
Step-by-step explanation:
To find the number of real roots for a quadratic, we apply the discriminate. The discriminate is the inside portion of the square root from the quadratic formula.
•
yields 2 real roots
•
yields 1 real root
• [tx]b^2-4ac<0[/tex] yields no real roots
Example:
where a=4, b=-7, and c=2
.
It has 2 real roots
