Answer:
12%
Step-by-step explanation:
Interés simple = Principal × Tasa × Tiempo
Tasa = Interés simple / Principal × Tiempo
Principal = 1700 soles
Tiempo = 1 año y 3 meses
12 meses = 1 año
3 meses = 3/12 = 1/4 = 0.25
Tiempo = 1.25 años
Tasa = 255 /1700 × 1.25
= 0.12
= 0.12 × 100
= 12%

what is the unit rate of 2250 pencils in 18 boxes
Answer:
184
Step-by-step explanation:
i did it this on a test a while back
Answer: 125 Pencils per Box
Step-by-step explanation:
This is a fraction equal to
2250 Pencils ÷ 18 Boxes
We want a unit rate where
1 is in the denominator,
so we divide top and bottom by 18
2250 Pencils ÷ 18
18 Boxes ÷ 18
=
125 Pencils
1 Box
=
125 Pencils
Box
= 125 Pencils per Box
REINFORCE Tickets to the zoo cost $18 for adults and $8.25 for children. One day, the zoo sold 2,300 tickets and collected $30,168 in ticket sales. How many children and how many adults attended the zoo that day? Write a system and solve it by graphing. Be sure to sketch you graph, give the solution, and define your variables.
Given:
The cost of adults ticket = $18
The cost of children's ticket = $8.25
Total tickets = 2300
Total revenue = $30,168.
To find:
The number of children and number of adults attended the zoo that day.
Solution:
Let x be the number of children and y be the number of adults.
Equation for tickets: [tex]x+y=2300[/tex] ...(i)
Equation for revenue: [tex]18x+8.25y=30168[/tex] ...(ii)
Plot the graphs of the given equations on a coordinate plane as shown below.
From the graph it is clear that the graph of both equations intersect each other at (1148,1152).
It means the number of adults is 1148 and the number of children is 1152.
It can be solved algebraically as shown below:
Substitute the value of y in (ii) from (i).
[tex]18x+8.25(2300-x)=30168[/tex]
[tex]18x+18975-8.25x=30168[/tex]
[tex]9.75x=30168-18975[/tex]
[tex]9.75x=11193[/tex]
Divide both sides by 9.75.
[tex]x=\dfrac{11193}{9.75}[/tex]
[tex]x=1148[/tex]
Putting [tex]x=1148[/tex] in (i), we get
[tex]1148+y=2300[/tex]
[tex]y=2300-1148[/tex]
[tex]y=1152[/tex]
Therefore, the number of adults is 1148 and the number of children is 1152.

Find the slope of the line.
A. -1/4
B. 4
C. 1/4
D. -4
Answer:
9. A. -1/4
Step-by-step explanation:
Plug the points into the equation y2-y1/x2-x1. In this case, I chose the points (0,-2) and (4,-3). This would make the equation -3--2/4-0. This would be equal to -3+2/4 or -1/4. Therefore, the slope is -1/4.

Dinner at olive garden cost $52.37. You Leave a 20% tip, What is the total cost
Answer:
62.84
Step-by-step explanation:
52.37 times 1.20(how you calculate tip) =62.84
Answer:
$62.84
Step-by-step explanation:
Tip is $10.47 add that with 52.37
If you want to leave a 20% tip, multiply the cost by 0.20 to get the tip amount or multiply the cost by 1.20 to get the total including tip.
If y varies directly with x and y = 28 when x = 4, what is y when x = 3?
Answer:
y=21
Step-by-step explanation:
Since x and y vary directly, they will be proportionate to each other. In this case, y is 7 times larger than x. We know this because 28/4=7. So, the equation that describes their relationship is y=7x. This means that to find y plugin x. Therefore, y=21 because y=7(3).
P + 3.89 = 19.74
Have a good weekend
Answer:

P = 15.85
3/5 divided by -3/4 as a fraction
Answer:
-4/5
Step-by-step explanation:
To solve, you have to use a reciprocal so that it becomes 3/5 times -4/3.
3/5 times -4/3 is -12/15.
-12/15 in simplest form is -4/5.
Your answer is -4/5.
I hope this helps, have a nice day.
Answer: -4/5
Step-by-step explanation:
First you got to do keep change flip so 3/5 will stay the same the division will turn into a multiplication sign and instead of -3/4 it will be 4/-3. So 3 times 4 equals 12 and 5 times -3 equals -15 the answer will be 12/-15 but when you simplify it ipyou will get -4/5

what equation represents the model shown below?
Given:
The algebra tiles of an equation.
To find:
The equation represented by the given model.
Solution:
On the left side of the model we have 4 tiles of (-x) and 3 tiles of (-1). So,
[tex]LHS=(-x)+(-x)+(-x)+(-x)+(-1)+(-1)+(-1)[/tex]
[tex]LHS=-4x+(-3)[/tex]
[tex]LHS=-4x-3[/tex]
On the right side of the model we have 8 tiles of (-1). So,
[tex]RHS=(-1)+(-1)+(-1)+(-1)+(-1)+(-1)+(-1)+(-1)[/tex]
[tex]RHS=-8[/tex]
Now, equate the LHS and RHS to get the equation.
[tex]-4x-3=-8[/tex]
Therefore, the equation for the given model is [tex]-4x-3=-8[/tex].

Which is the correct from of the quadratic formula?
Answer:
Step-by-step explanation:
The quadratic formula allows us to solve any quadratic equation that's in the form ax^2 + bx + c = 0.
(The quadratic formula helps us solve any quadratic equation. First, we bring the equation to the form ax²+bx+c=0, where a, b, and c are coefficients. Then, we plug these coefficients in the formula: (-b±√(b²-4ac))/(2a) .)

Step-by-step explanation:
The explenation is shown on the picture above.
Consider the equation:
X^2-6 = 2 – 18x
1) Rewrite the equation by completing the square
2) What are the solutions to the equation?
The equation should be rewritten by completing the square as x² + 18x + (18/2)² = 8 + (18/2)².
The solutions to the equation is x = -9 + √89 or x = -9 - √89.
What is a quadratic equation?In Mathematics and Geometry, the standard form of a quadratic equation is represented by the following equation;
ax² + bx + c = 0
Next, we would solve the given quadratic equation by using the completing the square method;
x² - 6 = 2 - 18x
x² + 18x = 8
In order to complete the square, we would have to add (half the coefficient of the x-term)² to both sides of the quadratic equation as follows:
x² + 18x + (18/2)² = 8 + (18/2)²
x² + 18x + 81 = 8 + 81
Part 2.
x² + 18x + 81 = 89
x² + 9x + 9x + 81 = 89
x(x + 9) + 9(x + 9) = 89
(x + 9)(x + 9) = 89
x = -9 + √89 or x = -9 - √89.

Solve for x. Enter the solutions from least to greatest. (x + 1)^2 - 36 = 0 Lesser x=____ Greater x=____
Answer: [tex]-7\ \text{and}\ 5[/tex]
Step-by-step explanation:
Given
The equation is [tex]\left(x+1\right)^2-36=0[/tex]
Solving it
[tex]\Rightarrow \left(x+1\right)^2=36\\\\\Rightarrow \left(x+1\right)=\pm\sqrt{36}\\\\\Rightarrow x+1=\pm6\\\Rightarrow x=-7,5[/tex]
So, the lesser value of [tex]x[/tex] is [tex]-7[/tex] and the greater value is [tex]5[/tex].

Which algebraic expression represents 10 less than a number?
A. n + 10
B. 10 – n
C. n – 10
D. 10n
Answer:
C
Step-by-step explanation:
It means a no minus 10. I hope this helps. Good luck
============================================
Explanation:
Consider an example of saying "10 less than 50" would mean we compute 50-10 = 40
Another example would be "10 less than 78" so we say 78-10 = 68
In general, we would use algebra to go from "10 less than a number" to "a number - 10" to n - 10
Whatever n is, we subtract 10 from it to get that expression.
From there, we replace n with various numbers. Eg: replace n with 50
n-10 = 50-10 = 40
-----------------
Be careful not to mix up "10 less than a number" with "10 is less than a number". The "is" being the difference. This single word will change what the symbol interpretation will be.
"10 is less than a number" translates to 10 < n

A school had $3,000 to spend on technology. They spent $350 on a new projector. The function f(x)=299x+350 gives the total amount of money spent on technology after buying x tablets. If a teacher finds the tablets on sale for $249 each, how will the function change? Select three statements that are true.
AThe y-intercept of the function will not change
b The domain of the function will change from 0≤x≤8 to 0≤x≤10.
cThe range of the function will not change
dThe y-intercept of the function will decrease by $50.
eThe domain of the function will change from 0≤x≤10 to 0≤x≤12.
fThe range of the function will change
Answer:
The y-intercept of the function will not change.
Step-by-step explanation:
The given function is:
[tex]f(x)=2x-4[/tex]
It is defined on the domain
.
We need to find the range:
The range is the set of output values.
[tex]2\leq x\leq 6[/tex]
Multiply 2 on each side.
[tex]4\leq 2x\leq 12[/tex]
Subtract 4 from each side.
[tex]4-4\leq 2x-4\leq 12-4[/tex]
[tex]0\leq f(x)\leq 8[/tex]
[tex]0\leq y\leq 8[/tex]
The range of the function is .
Therefore, the correct option is A. The y-intercept of the function will not change.
