Answer:
That would be negative 45 or - 45
Please correct me if im wrong
The perimeter is 2.5+ 2.5+2+3.5= 10.5 ft
The area is equal 6. I used the equation A= a=b/2*h
Hope this helped! Let me know if I can be of more assistance. <span />
To find the answer we can break the figure into two parts: a rectangle and a semi circle.
The perimeter of the rectangle:
(10+4)×2
=28 ft
The perimeter of the semi circle:
perimeter of a circle: 2×兀×radius
(The radius: 4/2)
We divide the perimeter by two as it is a semi circle,which is half the circumferece perimeter of a circle.
[2(3.14)(4/2)] / 2
=6.28 ft
We can then add up the numbers to find the answer, and remember that 4 cm is overlapped:
28+6.28-4
=30.28ft
Therefore the answer is 30.28ft.
Hope it helps!
Answer: 48 notebooks
Step-by-step explanation:
For this problem, we can set up an equation to find how many notebooks will fit on the bookshelf.
3/4x=36
This equation comes from the given information of the problem. Since a notebook is 3/4 in wide, we write 3/4x, where x is the amount of notebooks. The 36 is the total amount fo space.
x=48
Answer:
3x + y = 2
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
given
3x + y = - 12 ( subtract 3x from both sides )
y = - 3x - 12 ← in slope- intercept form
with slope m = - 3
• Parallel lines have equal slopes , then
y = - 3x + c ← is the partial equation
to find c substitute (- 1, 5 ) into the partial equation
5 = 3 + c ⇒ c = 5 - 3 = 2
y = - 3x + 2 ← equation in slope- intercept form
add 3x to both sides )
3x + y = 2 ← equation in standard form
