Answer:
v=2-2root7, v=2+2root7
Step-by-step explanation:
-2v+8(1+2v)=-90
-2-4v^2+8+16v=-90
6-4v^2+16v=-90
-4v^2+16v=-96
v=2-2root7, v=2+2root7
Answer:
Discount= $4.94
Final Price= $28.04
Step-by-step explanation:
Discount = original price x discount / 100
Discount= 32.99 x 15/ 100
Discount= 494.85/ 100
You save= $4.9485 ($494)
Final Price= original price - discount
Final Price= 32.99 - 4.9485
Final Price= $28.04
Answer:
43 miles/hr
Step-by-step explanation:
Use a conversion factor from km to miles while keeping track of your units:
70 km/hr x 0.62 miles/km = 43 miles/hr
Find all the prime factors of the three numbers. pick up the common factors, ONCE, then pick up the non-common factors one by one, multiply the factors, the product is the least common factor.
example: the least common multiple of 6, 8, and 15
6=2*3
8=2*2*2
15=3*5
Note: do not write 8 into 4*2, because 4 is not a prime number. you have to break the number down to prime factors only.
Notice that 6 and 8 have a common factor 2, so pick up the 2;
6 and 15 have a common factor of 3, so pick up the 3.
those are the only two shared factors, so 2×3
now pick up whatever is not shared:
the two 2s for 8 and the 5 for 15 is not shared, add 2, 2, and 5 to the multiplication: 2×3×2×2×5=120
120 is the least common multiples of 6,8, and 15
this is basically how it is done. I believe you can explain better in your own words.
Answer:
The graph for number 1 (about the bunnies) is C.
The graph for number 2 (about the kettle) is A.
Step-by-step explanation:
C because it is an exponential function.
And A because it is the only one decreasing in temperature.
