Answer: Hi The Answer would be 46.
Step-by-step explanation:
4c + 3p = 10.93....multiply by 7
7c + 2p = 13.31....multiply by -4
--------------------
28c + 21p = 76.51 (result of multiplying by 7)
-28c - 8p = - 53.24 (result of multiplying by -4)
------------------add
13p = 23.27
p = 23.27/13
p = 1.79 <== cost of 1 pencil pack
1.79/10 = 0.179 rounds to 0.18 <== unit price per pencil
Answer:
B. 75°
Step-by-step explanation:
When lines that are parallel are crossed by a transversal , angles in matching corners are equal and called corresponding angles
To get the value of the angle;
180°-105°= 75°.................sum of angles on a straight line
This angle corresponds to angle y because of the parallel lines DE and XY
Answer:
Part a) The ratio of the perimeters is 
Part b) The ratio of the areas is 
Step-by-step explanation:
Part A) What is the value of the ratio (new to original) of the perimeters?
we know that
If two figures are similar, then the ratio of its perimeters is equal to the scale factor
Let
z-----> the scale factor
x-----> the perimeter of the new triangle
y-----> the perimeter of the original triangle

we have

substitute

Part B) What is the value of the ratio (new to original) of the areas?
we know that
If two figures are similar, then the ratio of its areas is equal to the scale factor squared
Let
z-----> the scale factor
x-----> the area of the new triangle
y-----> the area of the original triangle

we have

substitute
