Answer:
15.7 percent of 80 = 12.56
Step-by-step explanation:
Percentage solution with steps:
Step 1: Our output value is 80.
Step 2: We represent the unknown value with $x$.
Step 3: From step 1 above,$80=100\%$
Step 4: Similarly, $x=15.7\%$.
Step 5: This results in a pair of simple equations:
$80=100\%(1)$.
$x=15.7\%(2)$.
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
$\frac{80}{x}=\frac{100\%}{15.7\%}$
Step 7: Again, the reciprocal of both sides gives
$\frac{x}{80}=\frac{15.7}{100}$
$\Rightarrow x=12.56$
Therefore, $15.7\%$ of $80$ is $12.56$

A garden hose fills a watering can at a rate of 2/3 gallon per minute. How long would it take to fill a 4 gallon watering can?
Answer:
6 minutes
Step-by-step explanation:
If you add 2/3 and 2/3 you get 4/3 ( 1 1/3) so you have one and a third of a gallon then you add 1 1/3 and 1 1/3 to get 2 and 2/3 then add 1 1/3 to 2 2/3 and you get 3 3/3 also known as 4
Zachary is standing in a stadium and has the option of running up a staircase or down a staircase for exercise.
The function f(x)= 1/25(∣4x∣+2x) will determine how many calories Zachary will burn if he runs up x steps. Use a negative value for x if he runs down the stairs. What does the domain represent in this function?
Answer:
R(All real numbers)
Step-by-step explanation:
We are given that the calories burn in x steps of running is given by
[tex]f(x)=\frac{1}{25}(|4x|+2x)[/tex]
We have to find the domain of this function.
We know that
|x|=[tex]x, x\geq 0[/tex]
-x, x<0
Therefore, the function
[tex]f(x)=\frac{1}{25}(4x+2x) ,x\geq 0[/tex]
[tex]\frac{1}{25}(-4x+2x) ,x<0[/tex]
[tex]f(x)=\frac{1}{25}(6x), x\geq 0[/tex]
[tex]\frac{1}{25}(-2x), x<0[/tex]
The function is defined for all values of x.
Therefore, the domain of f(x)=All real numbers (R)

32 * 9 = 12 * C
2. Divide each side by 12:
C = (9 * 32) /12
3. Reduce:
C = 24
Final proportion:

Reasoning Solve the system of linear equations using substitution. Use pencil and paper. Which expression would be easier to substitute into the other equation, in order to solve this problem? Explain your reasoning. x = 4y - 2 x + 4y =7
Answer:
x = 5 /2 , y = 9 / 8
Step-by-step explanation:
x = 4y - 2 ....... (i)
x + 4y =7 ....... (ii)
Substituting eqn (i) into eqn (ii);
(4y - 2 ) + 4y = 7
4y - 2 + 4y = 7
8y = 7 + 2 = 9
y = 9 / 8
substitute y = 9 / 8 in eqn (i)
x = 4 (9 / 8) - 2
x = 9 / 2 - 2
x = (9 - 4 ) / 2
x = 5 / 2

Find the intercept and you get (12,9)
how do i graph y=-x+3
Answer:
y=-x+3 follows the same equation as y=mx+b
3 is b, and b is the y-intercept. The y intercept is where the line crosses on the y axis, and -x is is m, which is the slope. However since its a variable, its point is on the same number as positive three on the y axis, so then its 3 on the x axis.
