Answer:
30 of the hats are baseball caps
Step-by-step explanation:
3/4s of 40 is 30
Step 1: Problem
Step 2: Concept
The area of the figure is the sum of the area of a triangle and a semi-circle.
Step 3: Method
Perimeters
Height of the triangle = 15cm
Base of the triangle = 2 x Radius of the semi-circle = 2 x 8 = 16cm
Radius r = 8cm
Step 4: Final answer
Area of the figure = Area of triangle + Area of semi-circle
= 120 + 200.96
= 320.96
Answer:
B
Step-by-step explanation:
Answer:
Part 1) The original triangle ΔJKL has the bigger area
Part 2)
Step-by-step explanation:
Part 1) Which triangle has a bigger area?
we know that
A dilation is a non rigid transformation that produce similar figures
If two figures are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent
In this problem
ΔJKL is similar to ΔWXY
The scale factor is 3/4
3/4 < 1
That means ---->The dilation is a reduction
therefore
The original triangle ΔJKL has the bigger area
Part 2) If m∠K = 48o, and m∠L = 62o, what is the measure of ∠W?
Remember that
If two figures are similar, then its corresponding angles are congruent
so
m∠J≅m∠W
m∠K≅m∠X
m∠L≅m∠Y
Find the measure of angle J
we know that
The sum of the interior angles in any triangle must be equal to 180 degrees
so
substitute the given values
therefore
