Answer:
Hi there!
The correct answer is 10 units²
Step-by-step explanation:
The area of a triangle is A= 1/2 Base * Height
then you need to replace the values that you given into the formula
A = 1/2 (4)(5)
Answer:
640g flour
16g salt
12g yeast
60ml oil
Step-by-step explanation:
300 x (4/3) = 400
so multiply all by 4/3
Answer:
x = 10
Step-by-step explanation:
The 2 chords are equal in length so
7x + 5 = 9x - 15
2x = 20
x = 10
7. To find the area of a triangle you use base x height /2. so the base is 10 and the height is 25 so you do 10 x 25 first which is 250 then divide by 2 which gives you 125 so the area of each pennant is 125 cm^2 ( the ^2 means squared)
8. To find the area of a square you do length x Width. Since for a square all sides are the same the length AND the width are both 450cm. Now you just do 450 x 450 which gives you 202,500 cm^2. BUT it asks for an answer written in SQUARE METRES so you have to change 450cm to metres making it 4.5 metres x 4.5 metres = 20.25 SO THE REAL ANSWER IS 20.25 M^2
Hope this helps you out!
<span>We use the Pythagoras Theorem to derive a formula for finding the distance
between two points in 2- and 3- dimensional space.</span>
Let
P<span> = (x 1, y 1) </span>
Q<span> = (x 2, y 2) </span>
be two points on the Cartesian plane
<span>Then
from the Pythagoras Theorem we find that the distance between P and Q is</span>
PQ=((x2-x1)^2+(y2-y1)^2)^0.5
In a
similar way
it can
be proved that if
P<span> = (x 1, y 1, z1) and </span>
Q<span> = (x 2, y 2, z2) are two
points in the 3-dimensional space, </span>
<span>the
distance between P and Q is</span>
PQ=((x2-x1)^2+(y2-y1)^2+(z2-z1)^2)^0.5
