Answer:
y = 3/4x
Step-by-step explanation:
The equation of a proportional relation is ...
y = kx
The value of k can be found by dividing by x:
y/x = k
For the given values, we find k to be ...
k = y/x = (3 ft)/(4 turns) = 3/4 ft/turn
The relationship can be written ...
y = 3/4x
Multiply <u>√2</u> by <u>√72</u>. The product is a <u>rational</u> number because <u>√144</u> can be simplified to an integer.
Step-by-step explanation:
As Landon has to prove that two product of two rational numbers, he has to choose two rational numbers from the list and then multiply and show that the product is also a rational number.
Let us define the rational numbers first
A number that can be written in the form of p/q where p,q are integers and q is not equal to zero, is called a rational number.
From the give =n list of rational numbers
Taking
√2 and √72

As we can see that the product of √2 and √72 is 12 which is also a rational number.
So,
Multiply <u>√2</u> by <u>√72</u>. The product is a <u>rational</u> number because <u>√144</u> can be simplified to an integer.

Answer:
132 cm²
Step-by-step explanation:
Consider the shape as a trapezoid with a rectangle added on top.
The area of the trapezoid is (7+19)/2 × 8 =104
The area of the rectangle is 7×4 = 28
Add the two areas: 104+28= 132
OR consider the shape as a tall rectangle with the two triangles added to the sides.
The area of the rectangle is 7(4+8) = 84
The area of the triangles is 8(19-7)/2= 48
[Each triangle is 24 cm²]
Add those areas
84+48=132
Same result: 132 cm²
