Answer:
The value of n is 5
Step-by-step explanation:
Here, we want to get the value of n
To get this, we will need to use the appropriate trigonometric identity
As we can see, n represents the opposite as it the side that faces the angle given
m is the hypotenuse as it is the side that faces the right angle
The last side is called the adjacent
The trigonometric identity we want to use is that which connects the opposite to the adjacent
The appropriate trigonometric identity to use in this case is the tan
Thus;
Mathematically, the tan is the ratio of the opposite to the adjacent
hence;
tan 30 = n/ 5 √3
n = 5 √3 * 1/ √3
n = 5

what is x in equation?
Answer:
x = 32
Step-by-step explanation:
x/4 + 2 = 10
subtract 2 on both sides
x/4 + 2 - 2 = 10 - 2
x/4 = 8
Multiply 4 on both sides
x/4 * 4 = 8 * 4
x = 32

Check:
32/4 + 2 = 10
8 + 2 = 10
10 = 10 CORRECT

Joshua is training for a race. The ratio of the number of minutes he runs to the number of miles he runs is 24 to 3. He plans to run 10 miles. How many minutes will it take him?
Answer:
Time taken to cover 10 miles = 80 minutes
Step-by-step explanation:
Given:
Ratio [Number of minutes : Number of miles runs] = 24:3
Find:
Time taken to cover 10 miles
Computation:
Number of minutes/Number of miles runs = Time taken to cover 10 miles / 10
24/3 = Time taken to cover 10 miles / 10
Time taken to cover 10 miles = 80 minutes

Answer:
k = 16/33
Step-by-step explanation:
Determine k so that 2/3,k and 5/8k are the three consecutive terms of an a.p
k - 2/3 = 5/8k - k
3k-2/3 = 5k-8k/8
Cross product
(3k-2)(8) = (3)(5k-8k)
24k - 16 = 15k - 24k
24k - 16 = -9k
24k + 9k = 16
33k = 16
k = 16/33
x - y = 11 and 3x + 10y = -6 How would I solve by substitution?
Answer:
y = - 3, x = 8
Step-by-step explanation:
x - y = 11, x = 11 + y
Lets solve this equation with substitution: 3x + 10y = - 6
3(11+y)+10y=-6
33+3y+10y=-6
13y=-39
y = - 3
x - (-3) = 11
x + 3 = 11
x = 8
Answer:
use the first equation and solve for the variables
Step-by-step explanation:
for example, to solve for x add y on both sides x=11+y and substitute that to the equation
3(11+y)+10y=-6
that should give you -3
then go back to the equation x=11+y
x=11+(-3)
x=8

Answer: ↓↓
Step-by-step explanation:
∠ABF and m∠60° are complementary since they form a right angle.
∠ABF + 60 = 90
∠ABF = 30°
∠ABF and ∠CBD are vertical angles so they're congruent.
∠CBD ≅ ∠ABF
∠CBD ≅ 30
∠CBD = 30°
∠ABC and ∠CBD are linear pair so they're supplementary.
∠ABC + ∠CBD = 180°
∠ABC + 30 = 180
∠ABC = 150

You have decided to purchase a car for $22,346.16. The credit union requires a 10% down payment and will finance the
balance with a 5.4% annual interest loan for 36 months. The sales tax in your city is 7.6%, and the license and title
charges are $125.13. Determine the amount that the credit union will finance you for. Round your answer to the nearest
cent.
a $24,179.10
c. $21,761.20
b. $24,169.60
d. $21,752.64
Answer:
(b) [tex]\$24,169.60[/tex]
Step-by-step explanation:
Given: Cost of car is [tex]\$22,346.16[/tex]
Sales tax is [tex]7.6\%[/tex]
The license and title charges are [tex]\$125.13[/tex]
To find: The amount that the credit union will finance.
Solution:
We have,
Cost of car[tex]=\$22,346.16[/tex]
Sales tax is [tex]7.6\%[/tex] of [tex]\$22,346.16[/tex]
Therefore,
sales tax [tex]=\frac{7.6}{100}\times22,346.16=\$1698.31[/tex]
The license and title charges [tex]=\$125.13[/tex]
Now, the amount that the credit union will finance is
cost of car[tex]+[/tex]sales tax[tex]+[/tex]the license and title charges
[tex]=\$22346.16+\$1698.31+\$125.13[/tex]
[tex]=\$24,169.60[/tex]
Hence, the amount that the credit union will finance is [tex]\$24,169.60[/tex].
So, (b) [tex]\$24,169.60[/tex] is correct.

The audio store normally sells a pair of speakers for $280. They are on sale this weekend for $224. What is the percent of decrease in price?
Answer: 20%
Explanation:
1. Turn it into a fraction (224/280)
2. Divide the numerator (224) by the denominator (280). (224÷280=0.8)
3. Subtract 1 by 0.8 (or 100% by 80%) that should give you the answer 0.2 (20%)
Checking work:
280x0.2=56
280-56=224

find the equation of the line shown;
Answer: Assuming it means slope-intercept, the answer would be y=-2x+9
y = -2x + 9 is the equation of the line given in the graph.
What is a Linear equation?A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. Sometimes, the aforementioned is referred to as a "linear equation of two variables," with y and x serving as the variables.
Given a graph of the line, Where we can see that the line passes through the coordinates (0, 9) and (1, 7)
From the slope-intercept formula of a line:
y = mx +c
Where m is the slope
And c is the value of y at x =0
Thus in our case,
c = 9
and slope m = (y - y )/(x - x)
m = (7-9)/(1-0)
m = -2
so, the equation of the line:
y = -2x + 9
Therefore, the equation of the line in the given Graph is y = -2x + 9.

Answer: Choice A. [tex](-\infty, \infty)[/tex]
This is the same as saying the set of all real numbers.
There are no restrictions to put on the domain, so there are no values to avoid. This is because there are gaps, jumps, or holes in the graph. It's one continuous single curve.
This curve stretches forever to the left and right. As it goes left, it moves up (rises to the left). As it moves right, it goes downhill (it falls to the right). Saying "rises to the left and falls to the right" is an informal way to describe the end behavior. The actual specific end behavior doesn't matter. What matters is both left and right sides go on forever.
A domain of the set of all real numbers means we can plug in any real number for x, and get some output for y, which is part of the range.
One way we can describe the set of all real numbers in terms of an inequality is to write [tex]-\infty < x < \infty[/tex] meaning that x is between negative and positive infinity, ie x is anything you want. The inequality [tex]-\infty < x < \infty[/tex] converts to the interval notation [tex](-\infty, \infty)[/tex]. Interval notation is a compact way of writing compound inequalities.
Three years ago Alicia was twice as old as her brother Carlos. In two more years Alicia will be just 50% older than Carlos. How old is Alicia today?
Answer:
13 yearsStep-by-step explanation:
Let the present age of Alicia be x
Let the present age of her brother be y
Three years ago;
Alicia age = x - 3
Her brother's age = y - 3
If three years ago Alicia was twice as old as her brother Carlos, then;
X - 3 = 2(Y-3)
x-3 = 2y - 6
x = 2y - 3 ...1
In two years time;
Alicias age = x+2
Her brother's age = y +2
If in two more years Alicia will be just 50% older than Carlos, then;
x+2 = y + 2 + (0.5(y+2))
x+2 = y+2 + 0.5y + 1
x+2 = 1.5y+3
x = 1.5y + 1 ...2
Equating 1 and 2;
2y - 3 = 1.5y + 1
2y - 1.5y = 1+3
0.5y = 4
y = 4/0.5
y = 8
Since x = 2y-3
x = 2(8) - 3
x = 16-3
x = 13
Hence Alicia will be 13 years old today
