3) There are 12 inches in a foot, so 144/12 equals 12 feet- the distance above the floor. 12 goes into 40 about 3 times. 3 feet + 12 feet equals about 15 feet.
4) When you want to find the percentage of something, you would take the percentage and move the decimal place two spaces to the left. So 45% becomes .45. Then you would multiply that by the number of houses. .45 times 36 equals 16.2. Rounded to the nearest whole number, 16 houses display holiday lighting.
Answer:
Angle 1 = 3 . 43.5+6 =136.5°
Step-by-step explanation:
To angles are supplementary when added up, the result is 180°.
So:
Angle 1 + Angle 2 = 180°
We know that angle 1 = 3x+6 and angle 2= x
So we get:
If we know now that x=43.5, we can calculate the value of angle 1.
Angle 1 = 3 . 43.5+6 =136.5°
Answer:
86 is a term in the sequence
Step-by-step explanation:
2; 6; 10; 14; 18;.....
T1=1*4-2=2
T2=2*4-2=6
T3=3*4-2=10
T4=4*4-2=14
T5=5*4-2=18
......................
Tn=n*4-2
n*4-2=86
n*4=88
n=88/4
n=22
86 is T22 in the sequence.
The answer is 13/85. You could find out the answer by doing the reprical multiplication.
Answer:
132 km^2
Step-by-step explanation:
For this type of question, we’re looking for the surface area (SA) for the shape.
To do this, use the surface area (SA) formula
SA = 2lh + 2lw + 2hw where l = length w = width & h = height
But before we go ahead, this formula is only used for triangular shapes. So what we’re going to do is find the surface area and then split it in half.
SA = 2(8)(6) + 2(8)(6) + 2(6)(6) / 2
SA = (2(48) + 2(48) + 2(36)) / 2
SA = (96 + 96 + 72) / 2
SA = 264/2
SA = 132
The surface area is 132 km^2
