Answer:
70 , 84 , 105
Step-by-step explanation:
sum their ages , 10 + 12 + 15 = 37
divide the amount by this sum to find the value of one part of the ratio.
259 ÷ 37 = 7 ← value of 1 part of the ratio , then
10 parts = 10 × 7 = 70 euros ← Tom's share
12 parts = 12 × 7 = 84 euros ← Mary's share
15 parts = 15 × 7 = 105 euros ← Bill's share
Limestone rocks dissolving in water. All other options are forms of physical weathering.
Answer:
The answer is below
Step-by-step explanation:
Let us assume that the length of the square be x. Therefore the area of the square is given as:
Area of square = length × length = x × x = x²
Given that the length of one side of the rectangle is twice the length of the other side. Let the length of the small side be a therefore the length of the long side = 2a
The area of the rectangle = length of small side × length of long side = a × 2a = 2a²
Since both the rectangle and square are to occupy the same space, hence:
Length of small side = a = 
, length of long side = 2a = 
The length of the sides are length of the square side divide by √2 () and twice the length of the square side divide by √2 ()
Answer:
The correct answer is option C.
Sin 45 degrees = square root of 2 divided by 2, cos 45 degrees = square root of 2 divided by 2, tan 45 degrees = 1
Step-by-step explanation:
The sin cos tan table used to calculate values of the ratios for different angles can be used for the values.
The table is easily available on the internet.
WE can use a a right-angles isosceles triangle to find the exact values for the angle 45.
The equal sides have length 1. So the thirs side using the pythagoras theorem will be √2.
So
Sin 45 = √2/2
Cos 45 = √2/2
and
Tan 45 = 1
So the correct option is C.
