Answer:
130 gallons initally, losing approx. 1.33333 gallons per minute, will be empty in approx 97.5 min
Step-by-step explanation:
1: y-intercept = (0, 130)
2: take two points (0, 130) & (30, 80)
use slope equation (80 - 130)/ (30 - 0) = -40/30 = -4/3
3: line equation is y=-4/3x+130
make y=0
0=-4/3x+130
-130=-4/3x
-130/-4/3=x
97.5=x
Answer:
160
Step-by-step explanation:
2² is 4 and the fourth multiple of 10 is 40.
Multiply those numbers together, and you get 160.
Answer:
400
Step-by-step explanation:
20/100 = 80/x
Cross multiply and divide
100 X 80 = 8000 / 20 = 400
Answer:
2.4
Step-by-step explanation:
40 percent * 6 =
(40:100)* 6 =
(40* 6):100 =
240:100 = 2.4
Now we have: 40 percent of 6 = 2.4
Question: What is 40 percent of 6?
Percentage solution with steps:
Step 1: Our output value is 6.
Step 2: We represent the unknown value with $x$.
Step 3: From step 1 above,$6=100\%$.
Step 4: Similarly, $x=40\%$.
Step 5: This results in a pair of simple equations:
$6=100\%(1)$.
$x=40\%(2)$.
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
$\frac{6}{x}=\frac{100\%}{40\%}$
Step 7: Again, the reciprocal of both sides gives
$\frac{x}{6}=\frac{40}{100}$
$\Rightarrow x=2.4$
Therefore, $40\%$ of $6$ is $2.4$
