Answer:
Less than
Step-by-step explanation:
2/3*3/4=6/12. 6/12=1/2. 1/2=2/4. 2/4 is less than 3/4.
Hope it helps!
Answer:
Step-by-step explanation:
Let a is the width of the window and diameter of the semicircle and let h be height of the rectangular portion of the window
:
Perimeter:
2h + a + .5x*pi = 21
2h + 2.57a = 21
2h = 21 - 2.57a
h = (10.5-1.285a)
:
What would be the window with the greatest area;
Area = semicircle + rectangle
Radius = .5a
A = (.5*pi*(.5a)^2) + h*a
Replace h with (10.5-1.285a
A = (1.57*.25a^2) + x(10.5-1.285a)
A = .3927a^2 - 1.285a^2 + 10.5a
A = -.8923a^2 + 10.5a
Find the max area by finding the axis of symmetry; x = -b/(2a)
a = 5.88 meter is the width with the greatest area
:
Find the max area
A = -.8923(5.88^2) + 10.5(5.88)
A = -.8923(5.88^2) + 10.5(5.88)
A = -30.85 + 61.74
A = 30.89 sq/ft is max area
Answer:
144 bracelets
Step-by-step explanation:
Ashley is making bracelets to sell. She wants to make at least $450. Each bracelet costs $18 to make. She is selling them for $30 each. What is the minimum number she can sell to reach her goal
Let us represent the minimum number of bracelets she can sell= x
Hence, our Equation is
$18 + $30 × x ≤ $450
$18 + 3x ≤ 450
3x ≤ $450 - $18
3x ≤ $432
x ≤ $432/3
x ≤ 144
The minimum number of bracket = 144 bracelets
Answer:
The answer is C.
Step-by-step explanation:
1 quarter note=2 eighth notes
1 eight note=2 sixteenth notes
so
1 quarter note=4 sixteenth note
so
times 3 both sides
3 quarter notes=12 sixteenth notes
