Answer:
8.14 feet
Step-by-step explanation:
8.14 feet will be more precise because it measures to the hundredths place, while 13.2 feet only measures to the tenths place.
Measuring to smaller place values increases precision and accuracy because the measurements are more likely to be more exact and correct.
So, 8.14 feet is more precise
Answer:
C. 10cm
Step-by-step explanation:
First we can rearrange the equation to solve for length (l):
V = lwh
Divide both sides by wh:
l = V/(wh)
Substitute in known values:
l = 1200/(15x8)
l = 1200/120
l = 10cm
Hope this helped!
Answer:
77
Step-by-step explanation:
To round 76.8 to the nearest whole number consider the tenths’ value of 76.8, which is 8 and equal or more than 5. Therefore, we have to round up: the whole number part of 76.8, 76, increases by 1 to 77, and the decimal point and all digits (.8) are removed.
76.8 rounded to the nearest whole number = 77
Answer:
-7/-9 pretty sure
Step-by-step explanation:
x2-x1
y2-y1
3-10= -7
1-10= -9
Answer:
1. x = 65
2. x = 40
3. x = -7
4. x = -4
5. x = -7
6. x = 4
Step-by-step explanation:
Angles in a triangle always add up to 180 degrees.
Thus, for each triangle you can write an equation setting the sum of the three angles equal to 180, and solving for x.
1. 180 = 80 + 35 + x
180 - (80 + 35) = x
180 - 115 = x
65 = x
2. 180 = 70 + 70 + x
180 - (70 + 70) = x
180 - 140 = x
40 = x
3. 180 = 76 + 41 + (x+ 70)
180 - (76 + 41) = x + 70
180 - 117 = x + 70
63 = x + 70
63 - 70 = x
-7 = x
4. (the red square means its a right angle = 90 degrees)
180 = 90 + 25 + (x + 69)
180 - (90 + 25) = x + 69
180 - 115 = x + 69
65 = x + 69
65 - 69 = x
x = -4
5. 180 = 50 + (57 +x) + (x + 87)
180 - 50 = (57 +x) + (x + 87)
130 = (57 +x) + (x + 87)
combine like terms
130 = 144 + 2x
130 - 144 = 2x
-14 = 2x
-7 = x
6. 180 = 80 + (9x + 4) + (16x - 4)
180 - 80 = (9x + 4) + (16x - 4)
100 = (9x + 4) + (16x - 4)
combine like terms
100 = 25x + 0
100 = 25x
4 = x
