Answer:
The difference is 8.56 cm. ( the metre is longer than the yard).
Step-by-step explanation:
1 yard = 36 inches
= 36 * 2.54
= 91.44 cm
1 metre = 100 cm.
When it comes to measurement, the most accurate estimate would be the whole number. A ruler has calibrated marks. It would be easy to locate 25. But when it is located between 25 to 26, you would have to estimate the decimal points. Generally, calibration marks are up to the tenths digit. For further digits, that would only an estimation. So, the estimated digit in this problem is 3 in the hundredths place.
Answer:
17 = x
Step-by-step explanation:
51 = 3x
~Divide 3 to both sides
17 = x
Best of Luck!
Answer:
x²+5x - 150 = 0
Step-by-step explanation:
Let the length be y and width be x
If the length of a swimming pool is 10 more than 2 times the width, then;
y = 2x+10 ...1
Since the Area is 300m²
A = xy
300 = xy .... 2
Substitute 1 into 2
300 = x(2x+10)
300 = 2x²+10x
Rearrange
2x²+10x - 300 = 0
Divide through by 2
x²+5x - 150 = 0
This gives the required quadratic expression
