namely is just the difference of 3/10 - 1/4, since the denominators are 10 and 4, the LCD will then be 20.
Answer:
66 inches
Step-by-step explanation:
v² = 55² + 26² - 2(55)(26) · cos 103°
v² = 3025 + 676 - [2860 · cos 103°]
v² = 3701 - (-643.4)
v² = 4344.4
v = ≈ 66
Answer:
1) $283.50
2) 65.21 meters.
Step-by-step explanation:
Part 1)
We know that a spool of ribbon holds 6.75 meters.
A craft club buys 21 spools.
So, the total length of ribbon bought is:
Each meter costs $2. So, the total cost will be:
Part 2)
A spool holds 6.75 meters.
We bought 21 of them, so that total length we have is 141.75 meters.
The club used 76.54 meters.
So, the amount of ribbon that is left is represented by:
Subtract:
So, 65.21 meters of ribbon will be left.
The answer is B.
If Farrah is 5 times older than Emil plus 4 years, the equation would be 5e+4.
The spring will be stretched 18.2 inches by force of 26 pounds.
Step-by-step explanation:
7 pound stretches the spring = 4.9 inches
Ratio of force to spring = 7:4.9
New force = 26 pounds
Spring stretched = x
Ratio of new force to spring = 26:x
Using proportion;
Ratio of force to spring :: Ratio of new force to spring
Product of mean = Product of extreme
Dividing both sides by 7
The spring will be stretched 18.2 inches by force of 26 pounds.
