Answer:
203 numbers are between 202 and 405
Step-by-step explanation:
405 - 202 = 203
Answer:
0.41 tons can be lifted
Step-by-step explanation:
The diameter d in inches of a rope needed to lift a weight of w tons is given by the formula d = 15w π .
This means that the diameter of the rope varies with the weight to be lifted. d is the dependent variable
π is a constant which is approximately 3.142
To determine the amount of weight that can be lifted with a rope with a diameter of 19.5 in, we substitute d = 19.5 into the given equation. It becomes
19.5 = = 15w ×3.142
19.5 = 47.13w
w= 19.5/47.13 = 0.41 tons
Answer:
(1, 4 )
Step-by-step explanation:
Given the 2 equations
y = x + 3 → (1)
y = 4x → (2)
Substitute y = 4x into (1)
4x = x + 3 ( subtract x from both sides )
3x = 3 ( divide both sides by 3 )
x = 1
Substitute x = 1 into either of the 2 equations and evaluate for y
Substituting into (2)
y = 4x = 4 × 1 = 4
Solution is (1, 4 )
Answer:
f(x)=4-3x
Step-by-step explanation:
f(x) = y
Isolate y
9x+3y=12
3y=12-9x
y=4-3x
f(x)=4-3x
they increased by 70 percent. divide 667 by 912 and you get 0.67237903 but you round to the tenths and get 70% because you move the decimal to the right twice
