<span><span /><span>In this problem, we are looking for the total
inches of ribbon that Risa needed in order to complete sewing all sides of the
Blanket.
She needs 72 inches per sides of the blanket.
A blanket is consisting of 4 sides, therefore multiply 72 by 4.
=> 72 x 4
=> 288 inches
or simply add 4 72s
=> 72 + 72 + 72 + 72
=> 288 inches</span></span>
Answer:
0.00375 inches
Step-by-step explanation:
Since the microscope makes the microorganism appear ×200 larger, that would mean we would have to divide by 200 to get the original size. 0.75/200= 0.00375.
Step-by-step explanation:
6 * 1 = 6
this means the circle can fit with 6 arcs each one of them has a length of 1.
so,
360° / 6 = 60° (Central angle for each arc)
Step 1:
x² + 4x = 192
Step 2:
Take x common:
x ( x + 4) = 192
Length is x and width is x+4
Step 3:
x² + 4x - 192 = 0
Step 4:
x² + 16x - 12x - 192 = 0
x(x+16) - 12(x+16) = 0
(x-12)(x+16) = 0
⇒ x=12, x=-16
Because the length can't be -16, the length is 12.
