Answer:
RT = 20
Step-by-step explanation:
Given S is at the midpoint of RT , then
RS = ST , that is
7y - 4 = 2y + 6 ( subtract 2y from both sides )
5y - 4 = 6 ( add 4 to both sides )
5y = 10 ( divide both sides by 5 )
y = 2
Then
RT = RS + ST = 7y - 4 + 2y + 6 = 9y + 2 = 9(2) + 2 = 18 + 2 = 20
So basically the fraction 1/6 is referring to the ratio of yards, where it represents 1 yard. 1/6 of 6 yards = 3 feet
Put it another way:
1/6 of 6 is 1. So that's 1 yard!
Answer:
B
Step-by-step explanation:
You must subtract the small volume from the bigger volume in this case you must do ![(4\pi x^{3} +32\pi x^{2} +64\pi x)-4\pi x^{3}](https://tex.z-dn.net/?f=%284%5Cpi%20x%5E%7B3%7D%20%2B32%5Cpi%20x%5E%7B2%7D%20%2B64%5Cpi%20x%29-4%5Cpi%20x%5E%7B3%7D)
Simplified is B
Answer:
k=45
Step-by-step explanation:
k
3
+3=18
Step 1: Simplify both sides of the equation.
1
3
k+3=18
Step 2: Subtract 3 from both sides.
1
3
k+3−3=18−3
1
3
k=15
Step 3: Multiply both sides by 3.
3*(
1
3
k)=(3)*(15)
k=45
Answer:
k=45
Step-by-step explanation:
2.4 x 104= 249.6
3.2 x 109= 348.8
249.6 to 3 sig is 250
348.8 to 3 sig is 349.
