Answer:
y = 20x
Step-by-step explanation:
y is the total amount that ricky will pay for the CDs.
x is the number of CDs that ricky bought.
so, in this case, if you replace the x by 600 :
y=20 x 600, witch means that the value of y is :
y = 12000 dollars.

Find the value of x. Your answer must be
Exact
Answer:
x = 8
Step-by-step explanation:
sin (30) = 4/x => solve for x.
Answer:
[tex]x=8[/tex]
Step-by-step explanation:
Use the sine ratio because we have the hypotenuse and side opposite the given angle to work with:
[tex]sineX=\frac{opposite}{hypotenuse}[/tex]
Insert the values:
[tex]sin30=\frac{4}{x}[/tex]
Multiply both sides by x:
[tex]x(sin30)=x(\frac{4}{x} )\\\\x*sin30=4[/tex]
Divide both sides by sin30°:
[tex]\frac{x*sin30}{sin30} =\frac{4}{sin30}\\\\x= \frac{4}{sin30}[/tex]
Insert the value of x into a calculator:
[tex]x=8[/tex]
OR:
The little red square means that angle is 90º, and the other given angle is 30°. Since every triangle has a measure of 180°, the other missing angle is 60°. The given triangle is a 30°-60°-90° triangle with the following rules:
[tex]long.leg=short.leg*\sqrt{3}\\\\hypotenuse=short.leg*2[/tex]
The hypotenuse is represented by the variable x. We are given the value of the short leg, which is 4. Solve for the hypotenuse:
[tex]h=4*2\\\\h=8[/tex]
Therefore, the value of x is 8.

Work out the value of angle x.
x
110%
Help:(
Answer:
40°
Step-by-step explanation:
Angles on a straight line add up to 180
180 - 110 = 70
As it's an isosceles triangle the opposite angles are the same
70 + 70 = 140
180 -140 = 40
Answer:
Step-by-step explanation:
180-110=70
x+70+70=180
x=180-140=40°

Suppose f(x)= 6x-5 . Describe how the graph of g compares with the graph of f. g(x)=f(x) +9
Answer:
Please check the graph attached.
Step-by-step explanation:
Given the function
f(x)= 6x-5
and
g(x)=f(x) +9
g(x)=f(x) +9 means 9 is added into the output of the parent function f(x).
It means the function g(x) would be shifted 9 units up.
Please check the attached diagram.
The red graph represents the graph f(x)= 6x-5.
It is clear that the y-intercept of the graph f(x)= 6x-5 is (0, -5)
The blue graph represents the graph g(x)=f(x) +9
It is clear that the y-intercept of the graph g(x)=f(x) +9 is (0, 4)
Conclusion:
It is clear that g(x)=f(x) +9 has been shifted up by 9 units from the f(x)= 6x-5.
what is the range of the function f(x)=7-3x when the domain is {-4, -2, 0, 2}?
Answer:
{19,13,7,1}
Step-by-step explanation:
Since the domain is the input we have to plug in each of those numbers to get the range ( or the output.) When we plug in -4 we get 19. When we plug in -2 we get 13, when we plug in 0 we get 7 and when we plug in 2 we get 1. (:

If a sphere of ice cream that was 2.5 inches in diameter was placed on top of the ice cream cone that had a height of 4 inches and a diameter of 1.75 inches and left to melt directly into the cone, would the all of the ice cream fit into the cone? Justify your answer using mathematics and a complete sentence answer.
Answer:
The cone would not the all of the ice cream fit into the cone.
Step-by-step explanation:
Geometrically speaking, the volume of the cone ([tex]V_{c}[/tex]), measured in cubic inches, is described by the following equation:
[tex]V_{c} = \frac{\pi}{3}\cdot r^{2}\cdot h[/tex] (1)
Where:
[tex]r[/tex] - Base radius, measured in inches.
[tex]h[/tex] - Height, measured in inches.
And the ice cream ball is described by the volume equation for the sphere ([tex]V_{s}[/tex]), measured in cubic inches:
[tex]V_{s} = \frac{4\pi}{3} \cdot R^{3}[/tex] (2)
Where [tex]R[/tex] is the radius of the ice cream ball, measured in inches.
In this case, the ice cream will fit into the cone if and only if [tex]V_{s} \le V_{c}[/tex]. That is:
[tex]\frac{4\pi}{3}\cdot R^{3} \le \frac{\pi}{3}\cdot r^{2}\cdot h[/tex]
[tex]4\cdot R^{3} \le r^{2}\cdot h[/tex]
If we know that [tex]r = 0.875\,in[/tex], [tex]h = 4\,in[/tex] and [tex]R = 1.25\,in[/tex], then the inequation is:
[tex]4\cdot (1.25\,in)^{3}\le (0.875\,in)^{2}\cdot (4\,in)[/tex]
[tex]6.25\,in^{3}\le 3.063\,in^{3}[/tex] (CRASH!)
Which leads to an absurd. Hence, the cone would not the all of the ice cream fit into the cone.
