Answer:
100 inches
Step-by-step explanation:
A triangle has a side length of 19inches and a perimeter of 95inches. A similar triangle has a corresponding side length of 20inches. Find the perimeter of the larger triangle.
This is calculated using proportion
Side length/Perimeter
Hence:
Side length of smaller triangle = 19 inches
Perimeter of smaller triangle = 95 inchee
Side length of larger triangle = 20 inches
Perimeter of larger triangle = x
19/95 = 20/x
Cross Multiply
19x = 95 × 20
x = 95 × 20/19
x = 100 inches
The perimeter of the larger triangle = 100 inches
The diagonals of a square bisect one another and are perpendicular.
so 21x+ 16.5 = 90
subtract 16.5 from each side
21x = 73.5
divide by 21 on each side
21x/21 = 73.5 /21
x = 3.5
<span>1C. 5^3 = 125 mL
2A. 30^3 = 27,000 mL = 27 L
3D. 75 mm is 7.5 cm, so we do: 7.5^3 = 421.875 mL = 0.421875 L =~ 0.422 L
Note:
1 mL = 1 cm^3
1 L = 1,000 mL
10 mm = 1 cm</span>
Let y=x+6 be equation 1...
Replace equation 1 in equation 2
X+6 =-2x-3
X+2x = -3 -6
3x = -9
X = -3
