The U.S. Mint pays $0.02 to produce every penny. How many pennies are produced when the U.S. Mint pays more than $6 million in production costs?
Answer:
300 millions
Step-by-step explanation:
The U.S. Mint pays to produce every penny = $0.02
When the U.S. Mint pays more than $6 million in production cost.
The number of pennies are produced = [tex]\frac{6,000,000}{0.02}[/tex]
= 300,000,000
U.S. Mint produced 300 million pennies.
The U.S mint pays $0.02 to produce every single penny in the country
Therefore the amount of pennies that will be produced when Mint pays above $6,000,000 can be calculated as follows
= 6,000,000/0.02
= 300,000,000
Hence the number of pennies that will be produced when they pay more than $6 million is 300,000,000

two parallel lines cut by a transversal. What is the value of x?
Answer: x = 37
Explanation: If two parallel lines are cut by a transversal,
then alternate interior angles are congruent.
So we can say that 3x + 4 = 115.
Subtracting 4 from both sides, we have 3x = 111.
Dividing both sides by 3, we find that x = 37.
So the value of x is 37.
The base of the triangle is seven less than twice its height. If the area of a triangle is 102cm², find the length of the base.
Answer:
The length of the base is [tex]b=17cm[/tex]
Step-by-step explanation:
We start by writing the equation of the base :
Given that the base of the triangle is seven less than twice its height we can write that
[tex]b=2h-7[/tex] (I)
Where ''b'' is the base and ''h'' is the height.
Now, the area of a triangle is [tex]\frac{bh}{2}[/tex]
We know that the area is [tex]102(cm^{2})[/tex] ⇒
[tex]\frac{bh}{2}=102(cm^{2})[/tex]
Now we can replace ''b'' by the expression in (I) ⇒
[tex]\frac{bh}{2}=102(cm^{2})[/tex]
[tex]\frac{(2h-7)(h)}{2}=102(cm^{2})[/tex]
Rearraging the expression :
[tex]\frac{(2h-7)(h)}{2}=102(cm^{2})[/tex]
[tex](2h-7)(h)=204(cm^{2})[/tex]
[tex]2(h^{2})-7h=204(cm^{2})[/tex]
[tex]2(h^{2})-7h-204(cm^{2})=0[/tex]
We need the values of ''h'' that satisfy the equation.
We can use the quadratic formula with
[tex]a=2\\b=-7\\c=-204[/tex]
The quadratic formula will be
[tex]h1=\frac{-b+\sqrt{b^{2}-4ac}}{2a}[/tex]
and [tex]h2=\frac{-b-\sqrt{b^{2}-4ac}}{2a}[/tex]
Using [tex]a=2\\b=-7\\c=-204[/tex] in the expression of h1 and h2 we find that
[tex]h1=12\\h2=-8.5[/tex]
Given that ''h'' is a length ⇒ [tex]h\geq 0[/tex]
We conclude that h1 = 12 cm is the correct value of ''h''
With this value of ''h'' we go to the expression of ''b'' ⇒
[tex]b=2h-7\\b=2(12)-7\\b=24-7\\b=17[/tex]
The value of the base ''b'' that satisfies the problem is [tex]b=17cm[/tex]

Answer:
[tex]V = (10a^3+91a^2+54a-792)[/tex]
Step-by-step explanation:
We have
[tex]V = lwh[/tex] (I), and
[tex]l=2a+11[/tex] (II)
[tex]w=5a-12[/tex] (III)
[tex]h=a+6[/tex] (IV)
We substitute the expression (II),(III) and (IV) in (I), that is
V= (2a+11)(5a-12)(a+6), solve the first one terms
[tex]V = (10a^2-24a+55a-132)(a+6)[/tex]
[tex]V = (10a^2+31a-132)(a+6)[/tex]
[tex]V = (10a^3+31a^2-132a+60a^2+186a-792)[/tex], simplifying
[tex]V = (10a^3+91a^2+54a-792)[/tex]

What is the radius of a circle whose equation is x2 + y2 + 8x – 6y + 21 = 0?
Answer: The required center of the given circle is 2 units.
Step-by-step explanation: We are given to find the radius of a circle with the following equation:
[tex]x^2+y^2+8x-6y+21=0~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]
The standard equation of a CIRCLE with radius 'r' units and center at the point (h, k) is given by
[tex](x-h)^2+(y-k)^2=r^2.[/tex]
From equation (i), we have
[tex]x^2+y^2+8x-6y+21=0\\\\\Rightarrow (x^2+8x+16)+(y^2-6y+9)-16-9+21=0\\\\\Rightarrow (x^2+2\times x\times 4+4^2)+(y^2-2\times x\times 3+3^2)-4=0\\\\\Rightarrow (x+4)^2+(y-3)^2=4\\\\\Rightarrow (x-(-4))^2+(y-3)^2=2^2.[/tex]
Comparing the above equation with the standard equation (i), we get
radius, r = 2 units and center, (h, k) = (-4, 3).
Thus, the required center of the given circle is 2 units.

A rectangle has the same area as a square. the long side of the rectangle is four times the length of the short side. the perimeter of the square has length 216 mm. how much longer is the perimeter of the rectangle than the perimeter of the square?
The perimeter of the rectangle is 54 mm longer than the perimeter of the square.
Explanation:To find the perimeter of the square, we can use the formula P = 4s, where P represents the perimeter and s represents the length of a side.
Given that the perimeter of the square is 216 mm, we can solve for the length of a side: 216 = 4s ⇒ s = 54 mm.
Since the area of the rectangle is the same as the square, we can calculate the length and width of the rectangle using the given information.
Let's assume the short side of the rectangle is x mm, then the long side would be 4x mm according to the given ratio.
Since the area of a rectangle is length × width, we have:
x × 4x = 54 × 54
4x² = 2916
x² = 729
x = 27 mm.
The perimeter of the rectangle can be calculated using the formula P = 2(length + width). Therefore, the perimeter of the rectangle is
P = 2(27 + 4 x 27) mm
P = 2(27 + 108) mm
P = 2(135) mm
P = 270 mm.
The difference in perimeter between the rectangle and the square is calculated by subtracting the perimeter of the square from the perimeter of the rectangle:
270 mm - 216 mm = 54 mm.
Therefore, the perimeter of the rectangle is 54 mm longer than the perimeter of the square.

Which trigonometric ratios are correct for triangle ABC? Check all that apply.
-sin(C) =
-cos(B) =
-tan(C) =
-sin(B) =
-tan(B) =
The correct trigonometric ratios for triangle ABC are sin(C) = 1 if C is the right angle, cos(B) = Adjacent/Hypotenuse, sin(B) = Opposite/Hypotenuse, and tan(B) = Opposite/Adjacent. Additionally, tan(C) is undefined if C is the right angle.
First, it's important to understand basic trigonometric ratios in a right-angled triangle. For triangle ABC, assuming angle C is the right angle:
sin(C) = Opposite/Hypotenuse. Since angle C is the right angle, sin(C) = 1.cos(B) = Adjacent/Hypotenuse. If angle B is one of the non-right angles, cos(B) can be found using the sides adjacent and opposite to angle B.tan(C) = Opposite/Adjacent. Since angle C is 90 degrees, tan(C) = Opposite/0 which is undefined.sin(B) = Opposite/Hypotenuse. This is the ratio of the length of the side opposite angle B to the hypotenuse.tan(B) = Opposite/Adjacent. This is the ratio of the length of the side opposite angle B to the side adjacent to angle B.These trigonometric ratios are correct and fundamental in solving various problems related to triangles.

What is the maturity value of a 3-month, 14% note for $50,000? (round your answer to the nearest dollar.)
a.$57,000
b.$51,750
c.$50,000
d.$52,000?
The maturity value of a 3-month, 14% note for $50,000 is calculated by first determining the interest over the 3-month period and then adding it to the principal. The interest is $1,750, resulting in a maturity value of b) $51,750.
The maturity value of a 3-month, 14% note for $50,000 can be calculated using the formula for simple interest: M = P + (P × r × t), where M is the maturity value, P is the principal amount, r is the annual interest rate (as a decimal), and t is the time in years. Let's calculate the interest first and then add it to the principal to find the maturity value.
First, convert the annual interest rate to decimal: 14% = 0.14.
Then, because the note is for 3 months (which is 3/12 or 0.25 of a year), the time period t is 0.25.
Now, calculate the interest: I = P × r × t = $50,000 × 0.14 × 0.25 = $1,750.
Finally, add the interest to the principal to get the maturity value: M = P + I = $50,000 + $1,750 = $51,750.
So, the correct answer is b. $51,750.
