Answer:
8 + 1.5x + 0.75y = pizza_cost
Step-by-step explanation:
It is given that every 10-inch cheese pizza costs ($8), meaning that this will be the constant.
Let (x) represent the number of inches added to the pizza. Since each extra additional inch costs ($1.5) thus one adds (1.5x) to the equation.
Let (y) represent the number of toppings. Every extra topping costs ($0.75) therefore one has to add (0.75y) to the equation.
Putting all of the elements together one gets the equation,
8 + 1.5x + 0.75y

5) A retailer bought a bag for $80 and sold it for $120. Calculate the percentage profit. *
Answer:
Profit Percentage = 50%
Step-by-step explanation:
Cost price, CP = $80
Selling price, SP = $120
Profit = 120 - 80 = $40
[tex]Profit \ \%= \frac{SP - CP}{CP} \times 100 \\\\Profit \ \% = \frac{ profit}{CP} \times 100 = \frac{40}{80} \times 100 = \frac{1}{2} \times 100 = 50 \%[/tex]

Calculate the amount she has left.
Answer:
if u have any doubts feel free to ask :)
Step-by-step explanation:
Sum of ratio : 9 + 7 + 4 = 20
a)
Adele share :
[tex]\frac{9}{20} \times 680 = 9 \times 34 = \$ 306[/tex]
b)
Barbara share :
[tex]\frac{7}{20} \times 680 = 7 \times 34 =\$ 238[/tex]
Collette share :
[tex]\frac{4}{20} \times 680 = 4 \times 34 = \$ 136[/tex]
c)
$ €
1.125 1
306 x
[tex]\frac{1.125}{306} = \frac{1}{x}[/tex] [cross multiply]
[tex]x =\frac{ 306} {1.125}[/tex]
x = €272
Adele receives = €272
d)
Apple Cost
1 kg 2.69
5 kg y
y = 2.69 x 5 = $13.45
Cost of 5kg of apples = $13.45
Cost of 3 kg bananas = 17.56 - 13.45 = $4.11
Banana Cost
3kg 4.11
1 kg z
[tex]z = \frac{4.11}{3}[/tex]
z = $1.37
Cost per kilogram of banana = $1.37
e) Collette share = $136
Half of it on clothes = (1/2) x 136 = $68
(1/5) of her share on books = (1/5) x 136 = 27.20
Balance amount with her = 136 - 27.20 - 68 = $ 40.80
The real numbers whose decimals do not end and do not repeat are (irrational numbers / rational numbers).
9514 1404 393
Answer:
irrational numbers
Step-by-step explanation:
The real numbers whose decimals do not end and do not repeat are irrational numbers.
__
If a decimal number ends or repeats, it can be represented by the ratio of two integers. That is the essence of a rational number.
Answer:
Irrational numbers
Step-by-step explanation:
Rational numbers are integers. They don't have repeating decimals.
An irrational number is not an integer, because irrational number are "not rational" and all integers can be represented as rational, so irrational numbers decimals repeat.

Dos personas A y B , se encuentran en la orilla de un río, separadas entre sí 200 m y en la orilla opuesta en el punto C, se encuentra otra persona. Los ángulos CAB= 65° y CBA = 57° .¿A que distancia de A se encuentra la persona C?. ayudaaaa porfaaaa):
Answer:
La distancia de C con respecto a A es de 197.788 metros.
Step-by-step explanation:
A manera de imagen adjunta construimos una representación del enunciado del problema, la cual representa a un triángulo cuyos tres ángulos son conocidos y la longitud del segmento AB, medida en metros, son conocidos. Por medio de la Ley del Seno podemos calcular la longitud del segmento AC (distancia de C con respecto a A), medida en metros:
[tex]\frac{AB}{\sin C} = \frac{AC}{\sin B}[/tex] (1)
Si sabemos que [tex]B = 57^{\circ}[/tex], [tex]C = 58^{\circ}[/tex] y [tex]AB = 200\,m[/tex], entonces la longitud del segmento AC es:
[tex]AC = AB\cdot \left(\frac{\sin B}{\sin C} \right)[/tex]
[tex]AC = (200\,m)\cdot \left(\frac{\sin 57^{\circ}}{\sin 58^{\circ}} \right)[/tex]
[tex]AC = 197.788\,m[/tex]
La distancia de C con respecto a A es de 197.788 metros.

Find the measure of C to the nearest degree.
Let the ∠C be : θ
From the figure, We can see that the Side which is opposite to angle θ is measuring 7 units
Also, We can notice that Hypotenuse is 11 units
As we are dealing with opposite and hypotenuse, we can clearly use Sinθ to find out the angle θ
We know that :
[tex]\bigstar \ \ \boxed{\sf{Sin\theta = \dfrac{Opposite \ Side}{Hypotenuse}}}[/tex]
[tex]\implies \sf{Sin\theta = \dfrac{7}{11}}[/tex]
[tex]\implies \sf{\theta = Sin^{-1}\bigg(\dfrac{7}{11}\bigg)}[/tex]
[tex]\implies \sf{\theta = 39.52^{\circ}}[/tex]
Answer : The measure of ∠C to the nearest degree is 38°

Triangle ABC with vertices A(0,0),
B(0,4), and C(3,0) is dilated to
form triangle ADE. What is the
E if D has coordinates
(0,6)?
106
Answer:
The coordinates of E are [tex]E(x,y) = \left(\frac{9}{2}, 0 \right)[/tex].
Step-by-step explanation:
The triangle ABC represents a right triangle as both sides AB and AC are orthogonal to each other. The side AB is in the y axis, whereas the side AC is in the x axis. The triangle is dilated with respect to the origin, in which point A is set.
Vectorially speaking, dilation is defined by the following operation:
[tex]P'(x,y) = O(x,y) + k\cdot [P(x,y) - O(x,y)][/tex] (1)
Where:
[tex]O(x,y)[/tex] - Point of reference.
[tex]P(x,y)[/tex] - Original point.
[tex]P'(x,y)[/tex] - Dilated point.
[tex]k[/tex] - Dilation factor.
By applying this operation, point B becomes point D:
[tex]B(x,y) = (0,4)[/tex], [tex]D(x,y) = (0,6)[/tex]
[tex]D(x,y) = (0,0) + k\cdot [(0,4)- (0,0)][/tex]
[tex]D(x,y) = (0,0) + k\cdot (0,4)[/tex]
[tex](0,6) = (0,0) +(0,4\cdot k)[/tex]
[tex](0, 6) = (0,4\cdot k)[/tex]
[tex]k = \frac{3}{2}[/tex]
Lastly, we transform point C into point E by applying the same operation: [tex]C(x,y) = (3, 0)[/tex], [tex]O(x,y) = (0,0)[/tex] and [tex]k = \frac{3}{2}[/tex]
[tex]E(x,y) = (0,0) + \frac{3}{2}\cdot [(3,0)-(0,0)][/tex]
[tex]E(x,y) = \left(\frac{9}{2}, 0 \right)[/tex]
The coordinates of E are [tex]E(x,y) = \left(\frac{9}{2}, 0 \right)[/tex].

Find the equation of the line with a slope of 2 and a point of (5,11)
PLEASE HELP !!!! THANKS !!!
Answer:
y=2x+1
Step-by-step explanation:
Hi there!
We are given the slope (m), which is 2, as well as the point (5,11).
We need to find the equation of the line.
There are 3 ways to write the equation of the line, but the most common type is slope-intercept form, or y=mx+b, where m is the slope and b is the y intercept
We're already given the slope (2), so we can substitute it into the equation right away
here's the equation so far:
y=2x+b
now we need to find b.
We can do this by plugging (5,11) into the equation, as the line passes through that point.
Substitute x as 5 and 11 as y
11=2(5)+b
multiply
11=10+b
subtract 10 from both sides
1=b
substitute 1 as b into the equation
y=2x+1
Hope this helps! :)
The polynomial 8x2 – 8x + 2 – 5 + x is simplified to 8x2 – gx – h. What are the value of g and h?
g = –9 and h = 7
g = 9 and h = –3
g = –7 and h = 7
g = 7 and h = 3
Answer:
Option D: g = 7 and h = 3
Step-by-step explanation:
The polynomial is;
8x² – 8x + 2 – 5 + x
Simplifying this gives;
8x² - 7x - 3
If this is simplified to 8x² – gx – h
Thus, by comparison of terms;
– gx = - 7x
-x will cancel out to get;
g = 7
Similarly, - h = - 3
Thus,h = 3
Therefore; g = 7 and h = 3
Answer:
Option D: g = 7 and h = 3
Step-by-step explanation:
The polynomial is;
8x² – 8x + 2 – 5 + x
Simplifying this gives;
8x² - 7x - 3
If this is simplified to 8x² – gx – h
Thus, by comparison of terms;
– gx = - 7x
-x will cancel out to get;
g = 7
Similarly, - h = - 3
Thus,h = 3
Therefore; g = 7 and h = 3

5 to the power -2 * 5x is equal to 1 solve for x
5^-2 * 5x = 1
Simplify:
5^-2 = 1/25
Now you have 1/25 * 5x = 1
1/25 x 5 = 1/5
1/5x = 1
Divide both sides by 1/5 ( when dividing by a fraction, flip the fraction over an multiply)
x - 1 x 5/1 = 5
X = 5
Answer:
x = 5
Step-by-step explanation:
This statement translates into 5^(-2)*5x = 1, which by rules of exponents simplifies to:
5x x
--------- = 1, or ----- = 1
5^2 5
Cross-multiplying, we get x = 5

Answer:
Area of the rectangle = x² - 3x - 10
2019
Step-by-step explanation:
Length of the rectangle = x + 2
Width of the rectangle = x - 5
Area of the rectangle = length × width
= (x + 2) (x - 5)
= x² + 2x - 5x - 10
= x² - 3x - 10
Area of the rectangle = x² - 3x - 10
C = 20t² + 135t + 3050
Where
C = the number of new cars
t = year the number of new cars was purchased
t = 0 corresponds to 1998
Find the when c = 15,000
C = 20t² + 135t + 3050
15,000 = 20t² + 135t + 3050
20t² + 135t + 3050 - 15,000 = 0
20t² + 135t - 11,950 = 0
4t² + 27t - 2390 = 0
Solve using quadratic equation
t = -b ± √b² - 4ac / 2a
= -27 ± √27² - 4(4)(-2390) / 2(4)
= -27 ± √729 -(-38240) / 8
= -27 ± √729 + 38240 / 8
= -27 ± √38969 / 8
= -27/8 + √38969/8 or 27/8 - √38969/8
= -3.375 + 197.41/8 or -3.375 - 197.41/8
= -3.375 + 24.67625 or -3.375 - 24.67625
t = 21.30125 or - 28.05125
t cannot be negative
Therefore,
t = 21.30125
To the nearest whole number
t = 21
Recall,
t = 0 corresponds to 1998
Therefore
1998 + 21 = 2019
c = 15,000 in the year 2019
find the value of x,y,z
Answer:
x y z are all equal to 60 because it on a line
Answer:
Step-by-step explanation:
40 + x + 80 = 180 degree (being linear pair)
120 + x = 180
x = 180 - 120
x = 60 degree
y + 120 = 180 degree (being linear pair)
y = 180 - 120
y = 60 degree
70 + 50 + z = 180 degree (being linear pair)
120 + z = 180
z = 180 - 120
z = 60 degree
x + y + z = 180 degree (being linear pair)
Note : A linear pair is a pair of adjacent angles formed when two lines intersect.
