Answer:
angle of elevation to the sun is 15.52°
Step-by-step explanation:
basketball goal 10 ft high casts a shadow 36 ft long
This forms a right angle triangle. the diagram is attached below
We need to find out angle A
We know opposite side = 10ft and adjacent side = 36 ft
We use tan formula
To find A we move tan to the other side, it becomes tan^-1
A = 15.52
So angle of elevation to the sun is 15.52°
The fish weighed 660 because 2÷132 is 66×10=660
A. x=6x+2
yup if that's wrong go to scoratic and take a picture of the question then it tells you what it actually is
Answer:
He must use 3 GB or less
Step-by-step explanation:
Total cost = flat fee + number of GB * charge per GB
We know he must stay under 30 dollars so change the equals to less than or equal to (the opening facing the 30) and replace the total cost with 30
30≥ flat fee + number of GB * charge per GB
We know the flat fee is 21 and the charge per GB is 3
30≥ 21 + number of GB * 3
Subtract 21 from each side
30-21 ≥ 21-21 + number of GB * 3
9≥number of GB * 3
Divide by 3
9/3 ≥ number of GB * 3/3
3≥ number of GB
He must use 3 GB or less
Answer:
First, you have to form simultaneous equation for both of their ages in yerms of a and b :
b = 4a - 12 -------- ( 1 )
a + b = 28 -------- ( 2 )
Next, you will have to solve it by substituting ( 1 ) into ( 2 ) :
a + (4a - 12) = 28
5a - 12 = 28
5a = 28 + 12
5a = 40
a = 8
Then, substitute a = 8 into ( 1 ) :
b = 4(8) - 12
b = 32 - 12
b = 20
