Answer:
7 and 2
Step-by-step explanation:
7 plus 2 is 9. 7 times 2 is 14.
Answer:
C
Step-by-step explanation:
Use the sine ratio in the left, right triangle to find the common side to both triangles and the exact values
sin60° = , cos45° = , thus
sin60° = = = ( cross- multiply )
2 × opp = 21 ( divide both sides by 2 )
opp =
Now consider the right triangle on the right, using the cosine ratio
cos45° = = = ( cross- multiply )
x = × = → C
2 times 2.5 times 1.5 times 10 equals to 75 square meters.
A percent is how many out of 100.
13/20 is how many out of 100?
You multiply the top and bottom by 5, as 5x20 is 100
13x5 is 65
Therefore, 65 out of every hundred cans, or 65%, are recycled
Answer:
Take a line segment AB = 2 units (consider 1 unit = 2 cm) on x-axis.
Draw a perpendicular on B and construct a line BC = 1 unit length.
Join AC which will be √5 (Pythagoras theorem). Take A as center, and AC as radius draw an which cuts the x-axis at point E.
The line segment AC represents √5 unit
