−5x−5y= −30 10x+3y= −3
Answer:
x = -3, y = 9
Step-by-step explanation:
-5x - 5y = -30
x - y = 6
x = -y + 6
10x + 3y = -3
10(-y + 6) + 3y = -3 (plug in x from the previous equation)
60 - 10y + 3y = -3
60 - 7y = -3
-7y = -63
y = 9
x = -y + 6
x = -(9) + 6
x = -3

A person whose eyes are 5 feet above the ground is standing on the runway of an airport 100 feet from the control tower. That person spots one of the air traffic controller at the window of the 132 foot tall tower. What is the angle of elevation to the nearest tenth of a degree?
Answer:
132-5 therefore the height from the eyes to the window is 127
100 feet away from the base of the tower
This forms two legs of a triangle
trying to find the degrees of this triangle.
Since its the two legs, you can use tanx which = to opposite side/adjacent side
Therefore, it is tanx = 127/100
But you are looking for x so arctan(1.27)
Must use calculator to find x.

The Weston family spends a maximum of
$50.00 per month on entertainment. Write and
graph an inequality to represent this.
Answer:
y < 50x
Step-by-step explanation:
In order to graph this inequality, you first need to identify the important word(s) here to find the inequality sign; in this case, it would be "maximum of $50" a month. Since it's a maximum of $50 a month (or less than $50 a month), you can write it as:
Where m is months and c is total cost, c < 50m
If you need to graph this, you can write it as y < 50x. The cost is y since it's the output, and months is x since that's the input.

Cindy throws one red and one blue regular (six-sided) fair dice. Find the probability that the sum of the two dice is greater than 2.
a 1/36
b 35/36
c 33/36
d 1
Answer:
5/36 is your answer.
Step-by-step explanation:
If the red die shows a "2", then the blue die must take on the values from the set {2,3, 4, 5, 6} in order for the sum of both dice to be larger than 4.
1+2=3
2+3 = 5
2+4 = 6
2+5 = 7
2+6 = 8
There are 6*6 = 36 total ways to roll two dice and exactly 5 ways to get the conditions stated above. The probability of getting a sum greater than 2 is 5/36
The probability that the sum of the two dice is greater than 2 will be 35/36. Then the correct option is B.
What is probability?Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences. Then the probability is given as,
P = (Favorable event) / (Total event)
Cindy throws one red and one blue regular (six-sided) fair dice. The total number of events will be
Total events = 6 x 6 = 36
The probability that the sum of the two dice is greater than 2 will be given as
P = 1 - 1 / 36
P = 35 / 36
The probability that the sum of the two dice is greater than 2 will be 35/36. Then the correct option is B.

Step-by-step explanation:

det = x * x - 4 * 3 = x^2 - 12
x^2 - 12 = 13

if the radius of the circle becomes two times what will be the new area of the circle
Answer: So when you double the radius, the area goes up by 4 times because 2 squared is 4. The area will always go up by the square of how much the radius goes up. By contrast, the circumference will only double -- from 12.56 to 25.12 because you do not square the radius (or diameter) -- you just multiply it by pi.

Find the area of the figure.
Answer and Step-by-step explanation:
For this shape, we have to draw a line that goes through the point that is inside of the shape from top to bottom.
This creates a square and two triangles.
The area formula for a triangle is A = [tex]\frac{bh}{2}[/tex]
The area of a square is A = b*b
Half of 3 is 1.5.
Triangles (Area combined):
Since there are two triangles that are the same, we only need to find the area of of 1 triangle, and not divide by 2.
A = 3 × 1.5 = 4.5
Square:
A = 3 × 3 = 9
Now, we add them together to get the total area of the figure.
9 + 4.5 = 13.5
The area of the figure is 13.5 [tex]in^{2}[/tex].

Step-by-step explanation:
Opposite sides of a parallelogram are equal.
16x - 15 = 11x + 30 Subtract 11x from both sides
16x - 11x - 15 = 30 Combine the left
5x - 15 = 30 Add 15 to both sides
5x = 30 + 15 Combine the right
5x = 45 Divide by 5
5x/5 = 45/5
x = 9

The polynomial 3x²+12x+14 cannot be factored by factoring out a GCF. Therefore, option D is the correct answer.
What is factorization?The factorization method uses basic factorization formula to reduce any algebraic or quadratic equation into its simpler form, where the equations are represented as the product of factors instead of expanding the brackets. The factors of any equation can be an integer, a variable, or an algebraic expression itself.
Here,
a) 9x²-81x+27
In the given trinomial, in each term 9 is the common factor, so, the GCF of the trinomial is 9.
Thus, 9(x²-9x+3)
b) 15x²+3x
The factors of each terms of binomial is listed below
15x²=3×5×x×x
3x=3×x
So, the GCF is 3x
Now, 3x(5x+1)
c) 2x+4
The factors of each terms of binomial is listed below
2x=2×x
4=2×2
So, the GCF is 2
Now, 2(x+2)
d) 3x²+12x+14
In this trinomial there is no common term.
Therefore, option D is the correct answer.

Lillian is going to invest in an account paying an interest rate of 5.7% compounded continuously. How much would Lillian need to invest, to the nearest ten dollars, for the value of the account to reach $7,600 in 7 years?
Answer:
The amount Lilian needs to invest is $5,160
Step-by-step explanation:
The parameters of the amount Lilian is going to invest in an account are;
The interest rate the account pays = 5.7%
The final amount the investment is expected to reach after the given time period = $7,600
The number of years of the investment = 7 years
The formula for compound interest is presented as follows;
[tex]A = P \cdot \left(1 + \dfrac{r}{n} \right)^{n\cdot t}[/tex]
Where;
A = The final amount = $7,600
P = The amount Lilian is to invest
r = The interest rate = 5.7% = 0.057
n = The number of times the interest is applied per time period = 1
t = The number of period that passes = 7 (years)
Therefore, we get;
[tex]7,600 = P \cdot \left(1 + 0.057 \right)^{7}[/tex]
∴ P = 7,600/(1 + 0.057)⁷ = 5,155.7123754
The amount Lilian needs to invest (rounded to the nearest ten dollars) for the value of the account to reach $7,600 in 7 years, P = $5,160
Use the distributive property to write an expression that is equivalent to 8(a + 4).
