Answer:
the answer is 3.6
Step-by-step explanation:
Step 1: Our output value is 24.
Step 2: We represent the unknown value with $x$.
Step 3: From step 1 above,$24=100\%$.
Step 4: Similarly, $x=15\%$.
Step 5: This results in a pair of simple equations:
24=100% (1)
x=15 (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
$\frac{24}{x}=\frac{100\%}{15\%}$
Step 7: Again, the reciprocal of both sides gives
$\frac{x}{24}=\frac{15}{100}$
$\Rightarrow x=3.6$
Therefore, $15\%$ of $24$ is $3.6$
<span>The line with m=2 @ x=3
y-y1=2(x-3)
You need to find y1.
because 2 line intersecting @ x=3 , y coordinate is the same as well.
Let's find it:
y=2/3 *3 -2=0
So point of intersection is: (3,0)
The equation of the desired line will be:
y-0=2(x-3)
y=2x-6</span>

Answer:
There are 9 pizza rolls and 12 mini hotdogs in the meal.
Step-by-step explanation:
We are given the following in the question.
Let x be the number of pizza rolls sold and y be the number of mini hotdogs in the combination meal.
Total number of items in combination meal = 21
Thus, we can write the equation:
Calorie in a pizza roll = 60
Calorie in a mini hotdog = 70
Total calories = 1380
Thus, we can write the equation:
Solving the two equations, we get,
Thus, there are 9 pizza rolls and 12 mini hotdogs in the meal.
Answer:
D
Step-by-step explanation:
The geometric sequence formula is:
An=a*r^(n-1)
An= nth term of the sequence
a= first term of the sequence. In this case, the amount Monica had in the first month
r= common ratio. In this case, is the interest rate, which is constant in all months.
n= number of periods
Following this equation, option A and B are not correct because "a" the first term of the sequence is $225.
It is not option C because Monica will have her first $225 plus interest not only the interest she gained, then the common ratio should be a number greater than 1.
It is option D and let´s proved it:
A6= 225*(1.04)^(6-1)
A6=225* (1.21665)
A6=$273.746
A6=$273.75
