Step-by-step explanation:
In 1985, the cost of clothing for a certain familiy was $620. In 1995, 10 years later, the cost of clothing for this famility was $1000. Assuming the cost increased linearly, what was the cost of this familiy's clothing in 1991
Answer:
$848
Step-by-step explanation:
Calculation for the cost of this familiy's clothing in 1991
First step is to calculate the amount that is increase per year
Increase per year= ($1000-$620)/(1995-1985)
Increase per year= 380/10
Increase per year= $38
Now let y be :38*x + $620 and let x be 6 years (1991-1985)
Second step is to calculate the cost of the clothing in 1991
y = 38*6 + 620
y=228+620
y = $848
Therefore the cost of this familiy's clothing in 1991 will be $848

Answer = 15/24
Step-by-step explanation:
Answer:
We are asked to find the area of the rectangle that has side lengths of 3/4 yard and 5/6 yard.
We know that area of rectangle is width times length.
To find the area of the given rectangle we will multiply both side length as:
Area of regatangle = width x Lenghth
Area of regtangle = 3/4 x 5/6 yard to the 2 power
Area of regtangle = 1/4 x 5/2 yard to the 2 power
Area of regtangle = 1 x 5/ 4x2 yard to the 2 power
Area of regtangle = 5/8 yard to the 2 power
Therefore, the area of the given rectangle would be 5/8 square yards.

In the figure below, k || o. Find the values of y and z.
Answer:
y = 112
z = 27
Step-by-step explanation:
Alright,
So we know that a straight line adds up to 180. And looking at the figure, it looks like 68 + y = 180 if you do some visualization.
So, we can already calculate y.
y = 180 - 68
y = 112
Now we find z. z here is represented in an expression. We can see that y and the expression z is in are congruent to each other which means they will equal each other. And since we know that y = 112, we know that the expression z is in is also equal to 112.
So we set up an equation like so:
112 = 3z + 31
And start to simplify:
81 = 3z
Finally we divide:
27 = z
Therefore, z is 27

Answer:
Solving the expression [tex]3x^2-2x=-1[/tex] we get: [tex]\mathbf{x=\frac{1+\sqrt{2}i }{3}\:or\:x=\frac{1-\sqrt{2}i }{3}}[/tex]
Step-by-step explanation:
We need to solve the expression: [tex]3x^2-2x=-1[/tex]
This is a quadratic expression and it can be solved using quadratic formula
Solving:
[tex]3x^2-2x=-1\\[/tex]
we can write it as:
[tex]3x^2-2x+1=0[/tex]
The quadratic formula is: [tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]
where a = 3, b = -2 and c= 1
Putting values and solving:
[tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\x=\frac{-(-2)\pm\sqrt{(-2)^2-4(3)(1)}}{2(3)}\\x=\frac{2\pm\sqrt{4-12}}{2(3)}\\x=\frac{2\pm\sqrt{-8}}{6}\\We\:know\:that\:\sqrt{-1}=i\\x=\frac{2\pm\sqrt{8}\sqrt{-1} }{6} \\We\:know\:\sqrt{8}=\sqrt{2\times 2 \times 2}=\sqrt{2^2 \times 2}=2\sqrt{2} \\x=\frac{2\pm2\sqrt{2}i }{6}\\Now,\\x=\frac{2+2\sqrt{2}i }{6}\:or\:x=\frac{2-2\sqrt{2}i }{6}\\x=\frac{2(1+\sqrt{2}i) }{6}\:or\:x=\frac{2(1-\sqrt{2}i) }{6}\\x=\frac{1+\sqrt{2}i }{3}\:or\:x=\frac{1-\sqrt{2}i }{3}[/tex]
So, solving the expression [tex]3x^2-2x=-1[/tex] we get: [tex]\mathbf{x=\frac{1+\sqrt{2}i }{3}\:or\:x=\frac{1-\sqrt{2}i }{3}}[/tex]

Revenue from Monorail Service, Las Vegas In 2005 the Las Vegas monorail charged $3 per ride and had an average ridership of about 28,000 per day. In December 2005 the Las Vegas Monorail Company raised the fare to $5 per ride, and average ridership in 2006 plunged to around 19,000 per day.
a. Use the given information to find a linear demand equation.
b. Find the price the company should have charged to maximize revenue from ridership. What is the corresponding daily revenue?
c. The Las Vegas Monorail Company would have needed $44.9 million in revenues from ridership to break even in 2006. Would it have been possible to break even in 2006 by charging a suitable price?
Answer:
A)The required linear demand equation ( q ) = -4500p + 41500
B) $4.61
$95680.55
C) No it would not have been possible by charging a suitable price
Step-by-step explanation:
A) find the linear demand equation
given two points ; ( 3, 28000 ) and ( 5, 19000 )
slope ( m ) = ( y2 - y1 ) / ( x2 - x1 )
= ( 19000 - 28000 ) / ( 5 - 3 ) = -4500
slope intercept is represented as ; y = mx + b
where y( 28000) = -4500(3) + b
hence b = 41500
hence ; y = -4500x + 41500
The required linear demand equation ( q ) = -4500p + 41500 ----- ( 1 )
p = price per ride
B ) Determine the price the company should charge to maximize revenue from ridership and corresponding daily revenue
Total revenue ( R ) = qp
= p ( -4500p + 41500 )
hence R = -4500p^2 + 41500p ------ ( 2 )
To determine the price that should maximize revenue from ridership we will equate R = -4500p^2 + 41500p to a quadratic equation R(p) = ap^2 + bp + c
where a = -4500 , b = 41500 , c = 0
hence p = [tex]-\frac{b}{2a}[/tex] = [tex]- \frac{41500}{2(-4500)}[/tex] = 4.61
$4.61 is the price the company should charge to maximize revenue from ridership
corresponding daily revenue = R = -4500p^2 + 41500 p
where p = $4.61
hence R = -4500(4.61 )^2 + 41500(4.61) = $95680.55
C) No it would not have been possible by charging a suitable price

About 0.12 dollars
Answer:
0•1254$ per pencil
Step-by-step explanation:
method 1
12 pencils = 1•49$
1 pencil = X ( unknown)
cross multiply
12x = 1•49$
divide both sides by 12x
X = 0•124$ per pencil
Method 2
you can simply divide the price of the pencils = 1•49$
by the number of pencils bought = 12
1•49/12
= 0•124$
What is the volume of a sphere with a radius of 24.2 ft, rounded to the
nearest tenth of a cubic foot?
Answer:
V is about 59335.5 cubic feet
Step-by-step explanation:
The formula to find the volume of a sphere is V=4/3πr^3.
If the radius is 24.2, we just need to substitute numbers into the equation.
V=4/3(3.14)(24.2^3)
V=4/3(3.14)(14172.488) **Find 24.2 cubed**
V=(4*14172.488)/3*3.14
V=(56689.952)/3*3.14 **Multiply the numerator**
V=18896.65067*3.14 **Divide the numerator by the denominator**
V=59335.48309 **Multiply by the simplified pi**
V is about 59335.5 cubic feet
It's a bit long of work but I hope I was able to have helped! Good Luck!
Answer:
The volume of given sphere is 59,335.5 cubic feet
Step-by-step explanation:
Given that
Radius of sphere=r= 24.2 feet
The volume of a sphere is calculated by the formula:
[tex]V = \frac{4}{3}\pi r^3[/tex]
We can use 3.14 or 22/7 for the value of pi
Putting the values, we get
[tex]V = \frac{4}{3} * 3.14 * (24.2)^3\\= \frac{12.56}{3} * 14,172.488\\=\frac{178,006.44928}{3}\\=59,335.48309[/tex]
Rounding off to nearest tenth of cubic feet
59,335.5 cubic feet
Hence,
The volume of given sphere is 59,335.5 cubic feet

∠B = 55°; ∠D = 55°
∠B = 55°; ∠D = 125°
∠B = 97°; ∠D = 97°
∠B = 83°; ∠D = 97°
Answer:
A. ∠B = 55°; ∠D = 55°
Step-by-step explanation:
Hope this helps :)
The measures of angles B and D are option (a) ∠B = 55°; ∠D = 55°
What is a parallelogram?A parallelogram is a shape whose opposite sides are parallel and congruent.
Thus, a parallelogram is always a quadrilateral but a quadrilateral can or cannot be a parallelogram.
Given; Angle B is (2 n + 15) degrees and angle D is (3 n minus 5) degrees.
The following is the step to determine the measures of angles B and D
We have,
angle B = 2n + 15
angle D = 3n - 5
The angles are opposite angles;
So,
angle B = angle D
This gives us;
2n + 15 = 3n - 5
Now Collect like terms;
3n - 2n = 15 + 5
n = 20
Then Substitute 20 for n in angle B = 2n + 15
angle B = 2 * 20 + 15
angle B = 55
Hence, the measures of angles B and D are option(a) ∠B = 55°; ∠D = 55°

Answer: Choice A) Angle-Angle-Side
This abbreviates to AAS.
==========================================================
Explanation:
AC bisects angle DAB, which tells us that angle DAC and angle CAB are the same measure (in this case, each is 106/2 = 53 degrees).
Because angle DAC = angle CAB, this forms the second "A" of "AAS". The first "A" is due to angle ABC = angle ADC.
The "S" refers to AC = AC by the reflexive property.
"Angle-Angle-Side" shortens to "AAS". Be sure not to mix it up with ASA which is a similar theorem. In the case of AAS, the side is not between the angles mentioned. If we knew that AB = AD, then we could use ASA.
