Answer:
Kirk wrapped 7 presents with those 23.8 cm of tape.
Step-by-step explanation:
Figure out the unit rate:
10.2 cm tape
-------------------
3 presents
or
3 presents
-----------------------
10.2 cm tape
Multiplying this by 23.8 cm results in the number of presents Kirk wrapped with that much tape:
(3 presents)(23.8 cm tape
--------------------------------------- = 7 presents
10.2 cm tape
Kirk wrapped 7 presents with those 23.8 cm of tape.

Answer:
y=0.3x
Step-by-step explanation:
Formula = 
y α x
y = kx
Where k is the constant of proportionality.
When y = 1.5; x = 5;
We substitute these known values in the equation,
y = kx
1.5 = k5
Dividing both sides of the equation by 5 to find the value for k, we have
1.5/5= k0.3/5
Therefore,
K = 0.3
Having found the value of k,
We substitute this value into the relationship
y = kx
Therefore we have,
y = 0.3x.
The direct variation function is therefore,
y = 0.3x.

Why is there a b) in the middle of the polygon? Question creators, proofread your figures.
a) Two triangles and a kite
Top triangle (1/2)(5.53)(1.5)
Bottom triangle (1/2)(6)(2)
The kite is like two triangles with shared base 2+3=5 and combined height 7,
(1/2)(5)(7)
Adding it up,
area = (1/2)(5.53)(1.5) + (1/2)(6)(2) + (1/2)(5)(7) = 27.6475
Answer: 27.6475 sq cm
b) Three triangles, including one right triangle
Area = (1/2) (6.7)(3) + (1/2)(6.2)(2.5) + 1/2(6.2)(2) = 24.
Answer: 24 sq cm
Answer:
If two things have the same shape and size then they are <em>congruent</em> to one another. If they are only the same shape but not size, then they are similar.
