We know that
<span>the length of the straw before it was folded is equal to the perimeter of the triangle
perimeter=12x</span>²-6 in
substitute the value of x
x=1.5 in
perimeter=12*(1.5)²-6-----> 21 in
the answer is
21 in
Answer:
length = 6 yards
width = 3.5 yards
Step-by-step explanation:
the length of a rectangle is 1 yard less than twice the width
LEt 'w' be the width of the rectangle
and 'l' be the length of the rectangle
length l = 2 times the width -1
so l = 2w -1
Area of the rectangle = length * width
Area = l * w
we know length is 2w-1 and given area = 21
21 = (2w-1) * w
subtract 21 on both sides
now solve for 'w'
0 = 2w(w+3)-7(w+3)
0= (2w-7)(w+3)
2w-7 = 0 and w+3 =0
w = 7/2 w=-3
width cannot be negative so we ignore w=-3
width w= 3.5
length = 2w-1= 2(3.5) - 1= 7-1=6
length = 6 yards
I believe you would do 2 times 3, which gives you 6. 3 is for the number of coin tosses, and 2 is the number of sides of a coin.
Answer:
19,324
Step-by-step explanation:
The original amount is 100% of the original amount since 100% means a whole amount.
A 21% increase means that the new amount will be 100% + 21% = 121% of the original amount.
Now we calculate 121% of 15,970.
To find a percent of a number, multiply the percent by the number. First, divide the percent by 100 to change it into a decimal.
121% of 15,970 =
= 121% * 15,970
= 1.21 * 15,970
= 19,323.7
Answer:
19,324
Answer is B, there are two equal base angles in an isosceles triangle, so given that ( 75+75 =150), the total of the interior angles in any triangle is 180, so 180-150 =30 ( which is the vertex angle) , the upper angle of the triangle.
