Answer:
Kara incorrectly factored 2(16x^2 + 24x + 9) she did not find the correct factors when she factored out. The correct factored expression would be 2(4x+3)^2
Step-by-step explanation:
32x^2 + 48x + 18
2(16x^2 + 24x + 9)
2(16x^2 + 12x) (12x + 9)
2 4x(4x + 3) 3(4x + 3)
2(4x + 3)(4x + 3)
2(4x + 3)^2
5, 10 ,15
divide each by 5
1,2, 3
so the ratios should be 1,2,3
Metal 1 : divide by 150
1,2,4
Metal 2 divide by 130
1,2,3
Metal 3 divide by 310
1,2,3
Metal 4 divide by 140
1,2,3
Metal 1 is not proportional
Choice A
Answer:
×=30⁰ :)
Step-by-step explanation:
x⁰+(x+30⁰)= 90⁰
x⁰+x⁰= 90⁰-30⁰=60⁰
2x⁰=60⁰
60⁰÷2=30⁰ => x⁰=30⁰
verification:
30⁰+(30⁰+30⁰)=90⁰
Answer: Our required probability is 0.067.
Step-by-step explanation:
Since we have given that
Number of days in a year = 365
Number of years = 10
So, Number of days in 10 years = 365 × 10 = 3650
Number of unprovoked shark bites in Florida = 246
so, Probability that there will be at least one unprovoked shark bite on a given day is given by

Hence, our required probability is 0.067.
Your answer would be
<span>h/f = k constant
67/10 = k = 6.7
H/21 = 6.7
H = 6.7 × 21 = 140.7 </span>
