Yulia estimates college tuition and fees, room and board, books, and other charges total $15,350. She will receive a $1500 scholarship. If she has 4 years to save, how much should Yulia save per month to cover the costs of college (minus the scholarship)? A. $288.54 B. $319.79 C. $3462.50 D. $3837.50

Answers

We know the the total cost of Yulia's college education is $15,350. We also know that she will receive a $1500 scholarship, so she will have to pay [tex]15350-1500=13850[/tex]$. A year has 12 months, so 4 years have [tex]4(12)=48[/tex] months.
Now to find how much she will need to save each month, we are going to divide the total cost of her college education by 48 months:
[tex] \frac{13850}{48} =288.54[/tex]

We can conclude that Yulia will have to save $288.54 per month to cover the costs of her college education. Therefore, the correct answer is: A. $288.54

What operations are needed to solve this word problem, and in what order should they be used?

addition and subtraction, in that order
addition and multiplication, in that order
subtraction and division, in that order
subtraction and multiplication, in that order

Answers

If we take the amount of points to be x before doing any operations on it ,
george has 2 times points of x
however x is 4 points less than sisters points which is 16 points
Then we subtract 4 from 16 = 12
12 is equal to x and george has twice of x
Therefore we first subtract 4 from 16 and then multiply it by 2, thats 12*2 = 24
therefore george has 24 points
the operations are subtraction and multiplication in order

Hello! 1,000 points are needed to go to a water park, and 424 points are already added, with 9 more games. An equation that would help find the average number of points is 9x + 424 = 1,000.

How to solve it:

Okay. So first off, lets subtract 424 from both sides. 424 - 424 cancels out. 1,000 - 424 is 576. That makes 9x = 576. Now, divide each side by 9 to isolate the c. 9x/9 cancels out. 576/9 is 64. There. x = 64. The team will need to score an average of 64 points in their remaining games in order to reach their goal.

Answers

1. 24,000 bc 6000*4

2. 42000 bc 8400*5

Her total investment in education is $96,000, the correct option is D.

What is Algebra?

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

We are given that;

Total= $6,000

At local mall=$26,000

Now,

To find the total investment in education, we need to consider both the direct costs and the opportunity costs of going to college. The direct costs are the expenses that Lindsey has to pay for her education, such as tuition, fees, books, etc. The opportunity costs are the income that Lindsey could have earned if she did not go to college, such as working at the local mall.

The direct costs of going to college are $6,000 a year for four years, which is $24,000 in total.

The opportunity costs of going to college are $26,000 a year minus $8,000 a year for four years, which is $18,000 a year or $72,000 in total. This is because Lindsey could have earned $26,000 a year at the mall, but she is only earning $8,000 a year while going to school.

The total investment in education is the sum of the direct costs and the opportunity costs, which is

$24,000 + $72,000

= $96,000.

Therefore, by algebra the answer will be $96,000.

What is the value of z in the equation 11 + z = 6?

66
5
−5
1

Answers

-5 will be your answer. Hope this helps!

Answer:

z = -5

Step-by-step explanation:

To find the value of z in the equation 11 + z = 6

we will simply subtract 11 from both-side of the equation. That is;

11 + z = 6

Subtract 11 from both-side of the equation

11 - 11 + z = 6 - 11

(On the left-hand side of the equation 11 will be subtracted from 11 which gives zero, thereby leaving us with just z while on the right-hand side of the equation 11 will be subtracted from 6 which will give negative 5)

z = -5

You change the equation into "graphable" equations

A graphing calculator can show you. The basic idea is that you graph the line that you would have if it were an equality, then you shade above or below (or left or right) according to the x and y values that satisfy the inequality. The symbol used does not include the "or equal to" case, so the line is graphed as a dashed line.

Part A)In a 45-45-90 triangle, what is the length of the hypotenuse when the length of one of the legs is 11 in.?

we know that
cos 45°=√2/2
[he length of the hypotenuse]=11/cos 45-----------> 11/(√2/2)----> (11*2)/√2
=22/√2-------> 11√2 in

the answer Part A) is 11√2 in

Part B) What is the exact value of sin 45° ?

the answer part b) is √2/2

Part C)
What is the area of a regular hexagon with a side length of 4 m?

we know that

In case of a regular hexagon each of the six triangles that are formed by connecting its center with all six vertices is an equilateral triangle with a side equaled to 4 m.
The area of this hexagon is six times greater than the area of such a triangle

In an equilateral triangle with a side d
the altitude h can be calculate from the Pythagorean Theorem as
h²=d²−(d/2)²=(3/4)d²
Therefore,
h=d√3/2

Area of such a triangle is
A=d*h/2------------> d²*√3/4
From this the area of the regular hexagon with a side d is
S=6*A----------> d²3√3/2
for d=4 m
S=4²3√3/2------> 24√3 m²------------> 41.57 m²

Given cosx=1213 and sinx=513 .

What is ratio for tan x ?

leave answer as a fraction in simplest form

Remember to show all of you work for credit!

Answers

Q1: Given sin(x+22)° = cos(2x−7)°

Using the concept of Right triangles and Trigonometric ratios, we can use a formula given as follows :-

If, sin(A) = cos(B). Then we must have A + B = 90 degrees.

We have sin(x+22)° = cos(2x−7)°

Then it must be true that (x+22)° + (2x−7)° = 90 degrees.

(x + 22) + (2x - 7) = 90

3x + 15 = 90

3x + 15 - 15 = 90 - 15

3x = 75

[tex] \frac{3x}{3} =\frac{75}{3} \\\\x = 25 \;degrees [/tex]

Hence, x = 25 degrees is the final answer.

Q2: Given cos(x) = 1213 and sin(x) = 513.

It says to find ratio of tan(x).

Using the concepts of Trigonometric ratios, We can the formula that relates all three functions i.e. sin(x), cos(x), and tan(x).

tan(x) = [tex] \frac{sin(x)}{cos(x)} [/tex]

We can plug the given values in the formula.

[tex] tan(x) = \frac{513}{1213} [/tex] is the final answer.
