Answer:
9k/64^2 (9k^2/64^2)
Step-by-step explanation:
Answer: 3/14
Step-by-step explanation:
3 * 2 = 6
4 * 7 = 28
6/28 = 3/14
Step-by-step explanation:
Since we have given that
Material needed to make a pillow cover is given by
We need to calculate the material which will be needed to make 9 pillows covers.
So, we use the "Multiplication Operation" as we need the value for more pillow covers :
Answer:
a. m<B = 100°
b. m<L = 55°
c. Scale factor = 9/11
Step-by-step explanation:
a) Similar triangles have their three corresponding angles congruent to each other, while the ratio of their corresponding sides are proportional to each other.
Since ∆ABC ~ ∆GLJ, therefore,
<A = <G,
<B = <J
<C = <L
m<J = 100° (given)
Therefore,
m<B = m<J = 100°
m<B = 100°
b) m<A = m<G
m<A = 25° (given)
Therefore,
m<A = m<G = 25°
m<G = 25°
m<L = 180° - (m<J + m<G)
Substitute
m<L = 180° - (100° + 25°)
m<L = 55°
c) scale factor of smaller triangle to the larger = side length of smaller triangle / corresponding side length of bigger triangle
Scale factor = AB/GJ
Substitute
Scale factor = 18/22
Simplify
Scale factor = 9/11
Answer:
B
Step-by-step explanation:
So we have the expression:
Since 5 goes into both 15 and 50, we can factor out a 5. First, rewrite the numbers as:
Factor out the 5:
So, our answer is B
And we're done!
