X is 10 take that’s known 80 degrees and the fact that it is a right angle means the whole this is 90 degrees so therefore x is 10 90=80+_
Answer: 45
Step-by-step explanation: To divide this start with finding how many times 585 goes into 13 which is 0. I put a picture for you to look at.
Answer:
(8, 11 )
Step-by-step explanation:
Given the 2 equations
2x + 2y = 38 → (1)
y = x + 3 → (2)
Substitute y = x + 3 into (1)
2x + 2(x + 3) = 38 ← distribute and simplify left side
2x + 2x + 6 = 38
4x + 6 = 38 ( subtract 6 from both sides )
4x = 32 ( divide both sides by 4 )
x = 8
Substitute x = 8 into (2) for corresponding value of y
y = 8 + 3 = 11
Solution is (8, 11 )
Answer:
Error = 1.167 feet
Percentage error = 0.3242%
Step-by-step explanation:
The original length of the soccer field = 120 yards long
Converting to feet
1 yard = 3 feet
120 yards = x
Cross Multiply
x = 120 × 3 feet
x = 360 feet
Measured length:
Han measures the length of the field using a 30-foot-long tape measure and gets a measurement of 358 feet, 10 inches.
We convert 10 inches to feet
1 inch = 0.0833 feet
10 inches = x feet
Cross Multiply
x = 10 × 0.0833 feet
x = 0.833 feet
The measured length = 358 feet + 0.833 feet
= 358.833 feet
The Error is calculated as:
|Measured length - Original Length)
= 360 feet - 358.833 feet
= 1.167 feet
Percentage Error
= Error/Original Length × 100
= 1.167/360 × 100
= 0.3241666667%
Approximately = 0.3242%
