Answer:
Answer:
17 seedlings
Step-by-step explanation:
Given;
The seedlings are at an equal distance in a straight line.
Distance between 3rd seedling and 5th seedling = 9/10 m
So, distance between 3rd seedling and 4th seedling = 9/10 ÷ 2 = 9/20 m
So, the distance between two seedlings in a line = 9/20 m
The given distance between 2nd seedling and the last seedling = 6 3/4 m = 27/4 m
Answer:
Step-by-step explanation:
Alvin takes pictures with his smartphone.
Of the pictures are animals.
of the animals are dogs.
To find which fraction of all pictures are pictures with dogs, you can simply multiply two fractions:
<u>Another way</u> to solve this question:
Let the number of all pictures be 24 (divisible by both 4 and 6).
Then the number of pictures with animals is
and the number of pictures with dogs is
Hence, the fraction of pictures with dogs of all pictures is
The ODE is linear:
Multiplying both sides by gives
Notice that the left side can be condensed as the derivative of a product:
Integrating both sides with respect to yields
Since ,
so that
Answer:
2500 x 6/100 = 150
150 x 5 = 750
2500 + 750 = 3 250
Step-by-step explanation:
You first have to determine the interest for one year. We know that a percentage means a 100 so we are going to use 6/100. You then have to multiple that by the original amount, you will then get your answer. After obtaining your answer your will multiple it by the number of years which is 5, once you get your answer add it to the original amount. Then you are all set.
Answer:
a) There is no solution to the equation.
b) Solution: x = 16
Step-by-step explanation:
Hi there!
a) Let´s write the equation:
√(x + 5) - 9 = -12
add 9 to both sides of the equation
√(x + 5) = -12 + 9
√(x + 5) = -3
Square both sides of the equation
x + 5 = 9
Subtract 5 to both sides
x = 9 - 5
x = 4
Let´s check the solution:
√(x + 5) - 9 = -12
√(4 + 5) - 9 = -12
√9 - 9 = -12
3 - 9 = -12
-6 ≠ -12
Then x = 4 is not a solution to the equation.
b) Let´s write the equation:
√(4x - 7) = √(3x + 9)
square both sides of the equation
4x - 7 = 3x + 9
subtract 3x and add 7 to both sides of the equation
4x - 3x = 9 + 7
x = 16
Let´s check the solution:
√(4x - 7) = √(3x + 9)
x = 16
√(4(16) - 7) = √(3(16) + 9)
√57 = √57
Then x = 16 is the solution to the equation
