Perimeter of the triangle is 30.75 inches.
Step-by-step explanation:
- Step 1: Given sides of the triangle = 11.25 in, 9.25 in, 10.25 in
- Step 2: Formula for perimeter of triangle = length of sides of the triangle
- Step 3: Substitute in the formula
Perimeter = 11.25 + 9.25 + 10.25
= 30.75 inches
Answer:
x= -4
Step-by-step explanation:
∠LMP + ∠PMN= 180° (adj. ∠s on a str. line)
-16x +13 -20x +23= 180
bring x term to 1 side, constant to the other:
-36x= 180 -13 -23
Simplify:
-36x= 144
x= 144 ÷ (-36)
x= -4
*The sum of the angles on a straight line is 180°
Answer:
4(3m^3-2m^2+4m+2)
Step-by-step explanation:
2L + 2W = 48
L= 15 feet
substitute the given value to the formula provided.
2(15) + 2W = 48
multiply 2 by 15
30 + 2W = 48
use the subtraction property of equality to cancel the value 30 on the left side.
30 - 30 + 2W = 48 - 30
cancel 30 on the left side leaving 2W while subtract 30 from 48.
2W = 18
divide both sides to get the value of the width.
2W/2 = 18/2
W = 9ft this is the final answer.
(a.)
Mean= sum / n
Mean= (123+116+122+110+175+126+125+111+118+117) / 10
Mean=1243 / 10
Mean= 124.3
Median:
Rearranged the data in order first
110,111,116,117,118,122,123,125,126,175
118 and 122 are at the middle
Median=1/2(n1 + n2)
Median=1/2(118+122)
Median=240/2
Median= 120
(b) 175 is the larger than the others value and larger than the mean, so it is the substantial difference between the mean and the highest value (175).
