Lily has at most $75 to spend on clothes. She wants to buy a pair of jeans for $30 and spend the rest on t-shirts. If each t-shirt costs $9, what inequality represents the maximum amount of t-shirts she could buy?
Answer:
The inequality represents the maximum amount of t-shirts she could buy is:
30x+9y≤75
Step-by-step explanation:
With the information provided, you can say that the result of adding up the price per jean for the number of jeans plus the price per shirt for the number of shirts has to be less than or equal to 75, which can be represented as:
30x+9y≤75, where
x is he number of jeans purchased
y is he number of shirts purchased

A. sin 30°
B. sin 45°
C. cos 45°
D. cos 60°
E. tan 30°

Step-by-step explanation:
Sin 45 or Cosine 45.
The trigonometric ratios that Garret could use to describe the relationship between these two sides are sin 30°and cos 60°.
What are Trigonometric Ratios?Trigonometric ratios are the ratios which is described for two sides of a right angled triangle.
The main three trigonometric ratios are sine, cosine and tangent functions.

Given that,
Garret makes a ramp for his skateboard in the shape of a right triangle.
Also given that,
length of the hypotenuse = 2 feet
Length of a leg = 1 feet
Using Pythagoras theorem,
Length of other leg = √(2² - 1²) = √3
45°-45°-90° triangle ratio is 1 : 1 : √2.
30°-60°-90° triangle ratio is 1 : √3 : 2.
Given triangle has the side ratio 1 : √3 : 2. So this is a 30°-60°-90° triangle.
The trigonometric ratio used must include the hypotenuse.
So sin and cos can only be used.
Hence the trigonometric ratios used are sin 30°and cos 60°.

Translate the following sentence into an equation using n for the unknown number. Then solve for n.
when 15 is decreased by three times a number, the result is 21
a.
15 - 372 = 21
n = -2
b.
312 - 15 = 21
n = -2
C.
31 - 15 = 21
n = 12
d.
15 - 3n2 = 21
n-2
Given:
15 is decreased by three times a number, the result is 21.
To find:
The equation for the given statement and solve it.
Solution:
Let n be the unknown number. Then,
Three times of a number = [tex]3n[/tex]
15 is decreased by three times a number = [tex]15-3n[/tex]
It is given given that the result after subtraction is 21. So,
[tex]15-3n=21[/tex]
[tex]-3n=21-15[/tex]
[tex]-3n=6[/tex]
Divide both sides by -3.
[tex]n=\dfrac{6}{-3}[/tex]
[tex]n=-2[/tex]
Therefore, the required equation is [tex]15-3n=21[/tex] and its solution is [tex]n=-2[/tex]. Hence, the correct option is (a).

The measure of the angle θ from the given triangle is 17.9°.
What are trigonometric ratios?The sides and angles of a right-angled triangle are dealt with in Trigonometry. The ratios of acute angles are called trigonometric ratios of angles. The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec).
From the given triangle, AC=13 and BC=4 units.
We know that, sinθ=Opposite/Hypotenuse
sinθ= 4/13
sinθ= 0.3076
θ=17.9°
Therefore, the measure of the angle θ from the given triangle is 17.9°.

James is solving a number puzzle that involves three integers, a, b, and c, where c is a positive integer. The product of a and b is 6. The product of a and c is -4. The product of b and c is -6.
Given:
Three integers, a, b, and c, where c is a positive integer.
The product of a and b is 6.
The product of a and c is -4.
The product of b and c is -6.
To find:
The values of a,b and c.
Solution:
According to the given information:
[tex]ab=6[/tex] ...(i)
[tex]ac=-4[/tex] ...(ii)
[tex]bc=-6[/tex] ...(iii)
From (ii), we get
[tex]a=-\dfrsc{4}{c}[/tex] ...(iv)
From (iii), we get
[tex]b=-\dfrsc{6}{c}[/tex] ...(v)
Putting [tex]a=-\dfrsc{4}{c}[/tex] and [tex]b=-\dfrsc{6}{c}[/tex] in (i), we get
[tex]\dfrac{-4}{c}\times \dfrac{-6}{c}=6[/tex]
[tex]\dfrac{24}{c^2}=6[/tex]
[tex]\dfrac{24}{6}=c^2[/tex]
[tex]4=c^2[/tex]
Taking square root on both sides, we get
[tex]\pm \sqrt{4}=c[/tex]
[tex]\pm 2=c[/tex]
It is given that c is a positive integer. So, it cannot be negative and the only value of c is [tex]c=2[/tex].
Putting [tex]c=2[/tex] in (iv), we get
[tex]a=-\dfrsc{4}{2}[/tex]
[tex]a=-2[/tex]
Putting [tex]c=2[/tex] in (v), we get
[tex]b=-\dfrsc{6}{2}[/tex]
[tex]b=-3[/tex]
Therefore, the values of a,b,c are [tex]a=-2,b=-3,c=2[/tex].

b+g=708
15b+10g=8640
Answer:
b=312
g=396
you can use substitution or elimination
Step-by-step explanation:
(b+g=708)10
(15b+10g=8640)1
(10b+10g=7080)-
(15b+10g=8640)
10b-15b=-1560
-5b=-1560
divide both sides by -5
b=312
then substitute
b+g=708
312+g=708
g=708-312
g=396
so b=312
g=396

Answer:
Radius of P = 5 cm
Step-by-step explanation:
Radius (r) of Q = 20 cm
Area of Q = 4 × Area of P
This means that:
Area of the quarter circle (Q) = 4 × Area of the circle (P)
Thus:
¼(πr²) = 4 × πr²
Plug in the values into the equation
¼(π*20²) = 4 × πr²
Find the value of r, which is the radius of P
¼(400π) = 4πr²
Multiply both sides by 4
400π = 4πr²*4
400π = 16πr²
Divide both sides by 16π
400π/16π = r²
25 = r²
Take the square root of both sides
√25 = √r²
5 = r
r = 5
Therefore, the radius of P = 5 cm

If 20 machines produce 1,240 printers in a day,
how many more machines are needed to produce
1,984 printers in a day?
Division is one of the four fundamental arithmetic operations. The number of machines that will be needed to produce 1,984 printers in a day is 32 machines.
What is Division?The division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.
Given that 20 machines produce 1,240 printers in a day. Therefore, the rate of production for a single machine can be written as,
Rate of production for a day = 1240/20 = 62 printer per machine
Now, the number of machines that will be needed to produce 1,984 printers in a day is,
Rate of production for a day = 1,984 / Number of machine
62 = 1984 / Number of machine
Number of machines = 32 machines
Hence, the number of machines that will be needed to produce 1,984 printers in a day is 32 machines.
