In parallelogram CNWK, ZC and ZK are consecutive interior angles. The
measure of ZC is (4a + 7)º and mZK = (7a – 3)º. What is mZC in
degrees?
Answer:
[tex] J. \:\:71\degree[/tex]
Step-by-step explanation:
CNWK is a [tex] ||^{gm} [/tex]
[tex] \therefore m\angle C + m\angle K = 180\degree [/tex]
(Adjacent angles of a parallelogram)
[tex] \therefore (4a+7)\degree + (7a-3)\degree = 180\degree\\\\
\therefore (4a+7+7a - 3)\degree = 180\degree\\\\
\therefore (11a+4)\degree = 180\degree\\\\
\therefore 11a+4 = 180\\\\
\therefore 11a= 180-4\\\\
\therefore a= \frac{176}{11}\\\\
\therefore a= 16\\\\
\because m\angle C = (4a+7)\degree\\\\
\therefore m\angle C = (4\times 16+7)\degree\\\\
\therefore m\angle C = (64+7)\degree\\\\
\huge \orange {\boxed {\therefore m\angle C = 71\degree}} \\\\

A store is offering a 30% discount on all jeans. If the regular price of a pair of jeans is $49.99, what is the sale price of the jeans?
Answer:
Sales price of jeans is $35Step-by-step explanation:
Step one:
given
percentage of discount= 30%
Regular price of jeans= $49.99
Required:
the price of the jeans after the discount is deducted
Step two;
let us solve for the amount of the 30% discount
=30/100*49.99
=0.3*49.99
=14.997
=$15 approx.
Hence the deduction in discount is $15
therefore the sale price after the discount is
=49.99-15
=$35
A local business was looking for a cleaning service to work on their property. They narrowed their choices down to companies. Molly maids company charges a flat rate of $100 per hour. Sparkly clean company charges $80 per hour plus $260 equipment fee. A) determine and state the number of hours that must be worked for the cost of both companies to be the same. B) if it is estimated to take at least 30 hours to company the job, which company will be less expensive? Justify your answer.
Answer:
A. 13 hours
B. Sparkly clean company
Step-by-step explanation:
Step one:
given
Molly maids company
charges a flat rate of $100 per hour
let the total charges be y
let the number of hours be x
the expression for the total charges for Molly maids is
y=100x---------------1
Step two:
Sparkly clean company
charges $80 per hour
equipment fee=$260
let the total charges be y
let the number of hours be x
the expression for the total charges for Sparkly clean is
y=80x+260---------------2
A) determine and state the number of hours that must be worked for the cost of both companies to be the same.
Equate equations 1 and 2
100x=80x+260
solve for x, collect like terms
100x-80x=260
20x=260
divide both sides by 20
x=260/20
x=13 hours
B) if it is estimated to take at least 30 hours to company the job, which company will be less expensive
x=30
Molly maids company
y=100x
y=100*30
y=3000
$3000
Sparkly clean company
y=80x+260
y=80*30+260
y=2400+260
$2660
Sparkly clean company will be less expensive for a 30 hour work
Let |q| = 5 at an angle of 45° and |r| = 16 at an angle of 300°. What is |q – r|?
The value of vector |q-r| = 18
What is Cosine Rule?The Cosine Rule can be used in any triangle relate all three sides to one angle.
Let OA =|q|
OB = |r|
BA = |q|-|r|
Hence ∠AOB = 45°+(360°-300)
∠AOB = 45°+60°
∠AOB = 105°
Given |q| = 5, |r| = 16
Now using cosine rule
|q-r| = √(16)²+(5)²-2×16×5×cos105°
|q-r| = 18

Given equation:
2(x + 2)² + p(x + 1) = 0The sum of the roots is q1 and the product of the roots is q2Need to show that q1+q2 = 0
SolutionBringing the equation into standard form of ax² + bx + c = 0:
2(x + 2)² + p(x + 1) = 0 2x² + 8x + 8 + px + p = 02x² + (p + 8)x + (p + 8) = 0Sum of the roots:
q1 = - b/a = -(p + 8)/2Product of the roots:
q2 = c/a = (p + 8)/2We see that q1 and q2 are opposite numbers, therefore their sum equals zero:
q1 + q2 = -(p + 8)/2 + (p + 8)/2 = 0=============================================

Find x so that l || m. Show your work.
Answer:
x = 22
Step-by-step explanation:
If l and m are parallel, then
(2x + 60) and 130° are same- side interior angles and are supplementary, thus
2x + 6 + 130 = 180 , simplify
2x + 136 = 180 ( subtract 136 from both sides )
2x = 44 ( divide both sides by 2 )
x = 22

Problem 9
1 liter = 1000 cubic cm
The base of the carton has area 50 cm^2, or 50 square cm.
Let A = 50 to represent the area.
The height h is unknown. It multiplies with the value of A to get the volume
V = A*h
1000 = 50*h
50h = 1000
h = 1000/50
h = 20
Answer: The carton is 20 cm tall
=======================================================
Problem 10
Part (a)
Along the 4 cm side of the box, we can fit 4/2 = 2 dice side by sideAlong the 7 cm side of the box, we can fit 7/2 = 3.5 = 3 dice. Note how I rounded down instead of up. Having 4 dice will lead to 4*2 = 8 cm, but 8 is larger than 7.Along the 5 cm side of the box we can fit 5/2 = 2.5 = 2 diceThis 3D configuration will allow us to fit 2*3*2 = 12 dice in total
Answer: 12 dice will fit
----------------------------
Part (b)
The box has volume 5*4*7 = 140 cubic cm
Each die has volume 2*2*2 = 8 cubic cm. There are 12 dice we can fit in, so 12*8 = 96 cubic cm is the amount of volume taken up by the dice
We have 140-96 = 44 cubic cm of empty air left over.
Answer: 44 cubic cm
=======================================================
Problem 11
1 liter = 1000 cubic cm
8 liters = 8000 cubic cm
So he has 8000 cubic cm of soil
The volume of the cube is
(22.5)^3 = (22.5)*(22.5)*(22.5) = 11,390.625 cubic cm
He won't have enough soil to completely fill the cube shaped planter
We can be able to determine this by recalling that 2^3 = 8, so (20)^3 = 8000. Meaning that a cube shaped planter of sides 20 cm will lead to a volume of 8000 cubic cm. Anything over 20 cm will lead to a larger volume.
So in short, spotting the 22.5 being larger than 20 is a quick way to know that the planter has more volume compared to the amount of soil he has.
Answer: He won't have enough soil to completely fill the planter
