Answer:
Kayla = $20.14
Michael = $19.08
The Difference = 1.06
Step-by-step explanation:
How to solve.
First, you need to add up how much Kayla is paying for the video game, plus the 6% tax.
19.00 + 6% = 20.14
Then, you need to do the same with Michael's.
18.00 + 6% = 19.00
To find the difference between how much Kayla and Michael paid for their items, you need to subtract their total.
20.14 - 19.00 = 1.06
and the nearest cent would be 1.10.

Answer: You'll have a quadrilateral with the following points
(5, -5)(4, -7)(6, -7)(8, -3)A diagram is posted below.
===================================================
Explanation:
The given quadrilateral has four unmarked points. I'll add the point labels A,B,C,D such that
A = (-3, 3)B = (-5, 2)C = (-5, 4)D = (-1, 6)I started at the lower right corner and worked my way clockwise.
----------------
Let's shift the line y = x-2 up two units so that it moves to y = x
We'll need to shift every point of the quadrilateral up two units as well.
So we have these new point locations after the shifting has occurred.
A' = (-3, 5)B' = (-5, 4)C' = (-5, 6)D' = (-1, 8)----------------
Now we need to reflect over the diagonal line. The rule to reflect over the line y = x is as simple as swapping the x and y coordinates.
So we can say [tex](x,y) \to (y,x)[/tex]
A point like (-3, 5) moves to (5, -3)
We have these new locations
A'' = (5, -3)B'' = (4, -5)C'' = (6, -5)D'' = (8, -1)----------------
The last thing to do is to shift everything down 2 units. This is to undo the first step we did when we shifted everything up by 2 units.
Doing this leads to these locations
A''' = (5, -5)B''' = (4, -7)C''' = (6, -7)D''' = (8, -3)Check out the diagram below.
Is this correct?!?! Pls let me know
Answer:
Nope. It isn't.
Step-by-step explanation:
6^2 + 8^2 = 100, and 100 = 10^2. So that means that the thing that you chose is incorrect.

Given that 198 = 2 x 3² x 11 and 90 = 2 x 3² x 5,
a) find the smallest integer, k, such that 198k is a perfect square
b) the largest integer that is a factor of both 198 and 90
(pls show working ty :) )
9514 1404 393
Answer:
a) 22
b) 18
Step-by-step explanation:
a) In order for 198k to be a perfect square, all of its integer factors must be squares. 3² is already a factor. To make the other factors be squares, need to multiply by 2 and 11. That is, k = 2×11 = 22. Then we will have ...
198k = 2×3²×11 × (2×11) = 2²×3²×11² = (2×3×11)²
k = 22
__
b) The factors that are different in the two numbers are 11 and 5. The factors that are the same are 2×3² = 18.
18 is the greatest common factor of 198 and 90
_____
The "work" is looking at the numbers in the factor lists and comparing those to what is needed to answer the question.
A rectangle Is (2x-3) cm long and (x+7) cm wide. What Is It's area?
Answer:
Step-by-step explanation:
Length (L)= 2x - 3 cm
Breadth (b) = x + 7 cm
Area of the rectangle
= L * b
= ( 2x - 3)(x+ 7)
= 2x(x + 7) - 3(x + 7)
= 2x² + 14x - 3x - 21
=( 2x² + 11x - 21) cm²
hope it helps
Answer:
[tex]2x^{2}[/tex] + 11x -21 [tex]cm^{2}[/tex]
Step-by-step explanation:
Area of a rectangle = Length × Width
= (2x-3)(x+7)
Multiply 2x with x, 2x with +7, -3 with x and -3 with +7
= [tex]2x^{2}[/tex] + 14x - 3x - 21
= [tex]2x^{2}[/tex] + 11x -21 [tex]cm^{2}[/tex]
Find the values of x and y plz
Answer:
x= 40, y= 140
Step-by-step explanation:
if two parellel lines cut by a transversal then same-side interior angles are supplementary.
180-140 = x
x = 40
x and y are suplementary
180-40 = 140
John planted a 4 foot tree in his backyard. The tree grows at a constant
rate of 2 feet every 5 weeks.
Answer:
There is not an actual question here, so i will answer this in a general way.
The initial height of the tree is 4 ft.
We know that every 5 weeks, the tree grows 2 ft
Then the rate at which the tree grows can be calculated as:
R = (how much it grows)/(in how much time)
Then:
R = (2 ft)/(5 weeks) = 0.4 ft/week
This means that the tree grows 0.4 feet per week.
Then we can write the equation:
H(w) = 4ft + (0.4ft/week)*w
Where w is the number of weeks since John planted the tree.
So if we want to know the height of the tree in a particular week, like week 3, we just need to replace w by 3 weeks in the above equation:
H(3 weeks) = 4ft + (0.4 ft/week)*(3 weeks)
= 4ft + 1.2 ft = 5.2 ft

Which conic section is represented by the following equation?
–5x2 + 9xy + 5y2 + 6x – 4y + 11 = 0
circle
ellipse
parabola
hyperbola
Answer:
B: Ellipse
Step-by-step explanation:
Just put in the equation on desmos. An ellipse will pop-up
The conic section is represented by the following equation –5x^2 + 9xy + 5y^2 + 6x – 4y + 11 = 0 is circle.
We have given that the equation of the equation is,
–5x^2 + 9xy + 5y^2 + 6x – 4y + 11 = 0
What is the general formula of the ellipse?The general formula of the circle is
[tex]ax^2+2xy+by^2+2fx+2gy+c=0[/tex]
Compare the given equation with the general formula of the circle so we get the equation of the circle

Last year, the ratio of literate and illiterate people of Rashkundu Village was
4:1. If the population of the village is 6550, let's find the numbers of literate
and illiterate people.
Step-by-step explanation:
Let the literate and illiterate people of Rashkundu Village be 4x and x respectively then 4x + x = 65505x = 6550x = 6550 / 5x = 1310Therefore no. of literate people = 4 * 1310 = 5240no. of illiterate people = 1310 Hope it will help :)Answer:
5,240 literate
1310 illiterate
Step-by-step explanation:
-ratio of literate : illiterate is 1:4
-add the numbers in the ratio (4+1=5)
-divide total population by 5 (6,550/5= 1,310)
-multiply the outcome by 4 to find the number of literate people (1,310*4=5,240 people)
-subtract the number of literate people from total population to find number of illiterate people (6,550-5,240= 1,310 people).

A grocer has two kinds of tea: one selling for 80 cents a pound and the other selling for 60 cents a pound. How many pounds of each kind must be used to make 50 pounds worth 74 cents a pound?
Answer:
35 pounds of tea for 80 cents.
Step-by-step explanation:
Equation::
value + value = value
80x + 60(50-x) = 74*50
80x + 60*50 - 60x = 74*50
20x = 14*50
x = 35 lbs (amt. of 80 cent tea to use)
50-x = 15 lbs (amt. of 60 cent tean to use)
Answer:
35 pounds of tea for 80 cents.
15 pounds of tea for 60 cents.
Step-by-step explanation:
x · 80 + y · 60 = 50 · 74
x + y = 50 · (- 60)
80x + 60y= 50 · 74
- 60x - 60y = -50 · 60
20x = 50 · (74-60) = 50 · 14
x = 50 · 14/20
35 pounds of tea for 80 cents.
y = 50 - 35 =
15 pounds of tea for 60 cents.

Answer:
49
Step-by-step explanation:
What two numbers add to the middle term and multiply to the last term? 49 doesnt fit in to 14 at all so we know that one of the factors is 7. since the middle term is -14, you would add -7 to -7 to get that. so we know the factors of the middle term are -7 and -7, so all you have to do is multiply them together. It would be positive 49.
