<span>A rectangle has two pairs of sides of equal length. </span>
<span>So perimeter P = 2ft + 18in + 2ft + 18in </span>
<span>The units have to be all the same to add them so.... </span>
<span>P = 2ft + 1.5ft + 2ft + 1.5 ft </span>
<span>P = 7 ft. </span>
<span>So the board would have to be 7 feet to make a 2ft x 1.5ft picture frame.</span>
Since 30 lights are 40% of them:
30*2= 60
Since 2*40= 80
We still need the 20 percent.
Half of 40= 20.
30/2= 15
So, 15+60= 75
75 is the number of lights on the tree.
I hope this helps!

The given data are:
A function that:
The domain is the set of all real numbers
One x-intercept
The amplitude is 4
The y-intercept is (0,0)
From the choices, the functions containing "cosine" can be eliminated since the described function passes through (0,0). So, we are left with two choices:
y = -4sin (x) and y = 4sin (x)
Given the amplitude of 4, the answer must be y = 4 sin(x)
Answer:
f^-1(x)=1/2x+5
Step-by-step explanation:
y=2x-10
inteechange 'y' with 'x'
x=2y-10
make 'y' the subject
2y=x+10
divide by 2both sides
y=(x+10)÷2
y=1/2x+5
f^-1(x)=1/2x+5
Answer:
Step-by-step explanation:
The authors use of figurative language gives the reader a better visualization of how the creature looked.
