Answer:
2.8 Miles
Step-by-step explanation:
If 7m is 60mins
How many miles is 24 mins
solution:
take unknown miles to be 'x'
7m=60mins
Xm=24mins
cross multiply
7×24/60=2.8m
x=2.8miles
If f(x) = √x and g(x) = 7x + b, then
f(g(x)) = f(7x + b) = √(7x + b)
If the plot of f(g(x)) passes through (4, 6), then
f(g(4)) = √(7•4 + b) = √(28 + b) = 6
Solve for b :
√(28 + b) = 6
(√(28 + b))² = 6²
28 + b = 36
b = 36 - 28
b = 8
Answer:
Okay so all you need to know is the percentage of the hydrogen peroxide.
We know that the total solution is 400 ml and the hydrogen peroxide solution is 8ml.
8/400
Percent means out of a hundred, this can go multiple ways.
<u>Way #1, benchmarking.</u>
So 8/400 simplified is 1/50 or 2/100.
1/50 is basically 2/100.
And percent means out of a hundred so 2/100 is basically 2percent.
<u>Way #2, proportions</u>
We want to know the percentage of hydrogen/ fabric dye
If you put it in numbers int he same fraction and put “x” as the unknown 8ml hydrogen peroxide solution you’d get.
8/400 = x/100
X/100 because percent means out of a hundred.
Now solve3
Cross multiply,
800 = 400x
divide 400 on both sides
2=x
Now plug it back in the proportion.
8/400 = 2/100
If you simplify to check if they are equal then it’s correct
Answer:
Not sure but my answers will be :
Sin S = 0.28
Sin R = 0.96
Cos S = 0.96
Cos R = 0.28
The answer would be 3, 6 times 3 is 18 and 18 minus 10 would be 8.
