Answer:
x=23.1822
Step-by-step explanation:
Since x is adjacent to the angle, and 24 is the hypotenuse, you use cosine. The equation would be cos(15)=x/24, which you cross multiply to make it x=24(cos(15)). 24(cos(15))=23.1822

Alex is not a smoker, but he lives near St. Louis, named the worst place in the U.S. for asthma sufferers by the Asthma and Allergy Foundation of America in 2009. The group rated St. Louis low for having poor air quality and because it doesn’t have as many laws as other places keeping indoor areas smoke free.
Based on this evidence, what can you conclude about asthma sufferers in St. Louis?
A. St. Louis is the only city in the United States where asthma is common.
B. Poor air quality and indoor smoking can cause problems for asthma sufferers.
C. Poor air quality and indoor smoking have no effect on asthma sufferers.
D. There are more asthma sufferers in St. Louis than any other city in America.
Answers
Answer: Hi! I would say it is D because the other answers really don’t make sense. And the passages said that they were rated low for air quality.

The cube root of r varies inversely with the square of s. Which two equations model this relationship?
Answers
Step-by-step explanation:
³√r =(k×1/s²)
³√r = k/s²
The equation given in the option which shows the relationship given in the question is ∛r = k/s²and [tex]\rm s^2 r^{1/3} = k[/tex], the correct options are B and C.
What is Inverse Variation?When a variable varies inversely with the other variable, i.e. on increasing one variable the other decreases is called Inverse Variation.
The statement for modelling the relation is
The cube root of r varies inversely with the square of s.
∛r ∝ (1/s²)
∛r = k/s²
Here k is the proportionality constant
The equations which model this relationship is given by ∛r = k/s²and [tex]\rm s^2 r^{1/3} = k[/tex].

Which system of inequalities is shown?
A y<x y>4 B y>x y
Answers
Given:
The graph of the system of inequalities.
To find:
The system of inequalities.
Solution:
In the given graph, we have two dotted boundary lines.
First boundary line is passes through (-1,1), (0,0) and (1,1), so it represents a proportional relationship and the equation of this boundary line is
[tex]y=x[/tex]
Second boundary line is a horizontal line passes through the point (0,4). So, the equation of this boundary line is
[tex]y=4[/tex]
Shaded portion lies below these boundary line and these boundary lines are dotted. So, the sign of inequity must be <.
The system of inequalities is
[tex]y<x[/tex]
[tex]y<4[/tex]
Therefore, the correct option is D.

Your dinner costs $21.50 before tax. If you used a fifteen percent off coupon
and then you are charged seven percent sales tax, what is your balance with tax?
Answers
Answer:
$19.55
Step-by-step explanation:
Discount = 15% of 21.50
= 0.15 * 21.50
= 3.225
= $ 3.23
Balance need pay = 21.50 - 3.23 = $ 18.27
Tax = 7% of 18.27
= 0.07 * 18.27
= $1.28
Balance with tax = 18.27 + 1.28 = $ 19.55
An engineer is designing a television screen. The screen is shaped like a rectangle with a diagonal of 34
inches. The ratio of the length of the rectangle to its width must be 15:8.
What is the length of the screen?
A. 30 in.
B. 23 in.
c. 32 in.
D. 15 in.
Answers
Answer:
30"
Step-by-step explanation:
length:width = 15:8
length = 15x
width = 8x
(15x)² + (8x)² = 34²
225x² + 64x² = 34²
289x² = 34²
x² = 34²/289
x = 34/17 = 2
length = 15x = 30 inches

Answers
Answer:
is first one and last one
Step-by-step explanation:
Answer: Option (4) is correct. 75( 5r + 3d + 4f ) expression represents the cost for making 75 bouquets.
Step-by-step explanation:
Given: r is the cost of a rose, d is the cost of a daisy, and f is the cost of a bundle of green filler.
Terry uses 5 roses, 3 daisies, and 4 bundles of green filler to make one bouquet.
Thus, cost of one bouquet = cost of each flower used × number of flower used.
Total cost of one bouquet= 5r+3d+4f
Thus, cost for making 75 bouquets = 75 × cost of one bouquet
= 75( 5r + 3d + 4f )
Thus, option (4) is correct. 75( 5r + 3d + 4f ) is the correct expression to represents the cost for making 75 bouquets

What is an algebraic expression?An algebraic expression is consists of variables, numbers with various mathematical operations.
The given expressions are (3y + 1) + (2y + 8) and (ny + 9)
Also, both the expressions are equivalent to each other.
To find the value of n, equate expressions (3y + 1) + (2y + 8) and (ny + 9),
3y + 1 + 2y + 8 = n y + 1
5y + 9 = n y + 1
5y + 9 - 1 = n y

A waterwheel is being turned by a stream at a rate of 3 revolutions per minute. If the diameter of the wheel is 15 ft, then how fast is the stream flowing
Answers
Answer:
0.7176 m/s m/s
Step-by-step explanation:
We are given;
Rate = 3 rev/min
Diameter: d = 15 ft
Now, we want to find how fast the stream is flowing which is the linear velocity.
Thus;
linear velocity = circumferential distance × number of revolutions
Now, circumferential distance = πd
Circumferential distance = 15π
Thus;
linear velocity = 15 × π × 3 = 45π ft/min
Converting to m/s gives;
Linear velocity = 45π/197 m/s
Linear velocity = 0.7176 m/s

Answer:
The equation of the line with a slope of 2 and a y-intercept of 4 in the slope-intercept is:
y = 2x + 4Hence, option 'A' is correct.
Step-by-step explanation:
The slope-intercept form of the line equation
y = mx+b
where
m is the slope b is the y-interceptIn our case, we are given
Slope m = 2y-intercept b = 4substituting m = 2 and b = 4 in the slope-intercept form of the line equation
y = mx+b
y = 2x + 4
Therefore, the equation of the line with a slope of 2 and a y-intercept of 4 in the slope-intercept is:
