Mr. Smith wants to order some pizza and cheese pizza cost $11 and pepperoni pizza cost $12.50 if you bought 13 pieces total and paid $153.50 how many pepperoni pizza did he buy
Answer: Mr Smith bought 7 pepperoni pizza
Step-by-step explanation:
Step 1
cost of cheese pizza =$11
pepperoni pizza cost =$12.50
let number cheese pizza be represented as c
and number of pepperoni pizza be represented as p
such that the total number of pizza bought which equals 13 can be represented as
c+ p= 13
and total cost of both pizza can be expressed as
11c+ 12.50p =153.50
Step 2 Solving
c+ p= 13
11c+ 12.50p =153.50
By elimination method, Multiply equation 1 by 11 and subtract the new equation from equation 2
11c+ 12.50p =153.50
11c+ 11p=143.
1.5p =10.5
p= 10.5/ 1.5 =7
c+ p= 13
c= 13-p =13-7=6
Therefore Mr Smith bought 6 cheese pizza and 7 pepperoni pizza

Work out the perimeter of a regular octagon with side length 2.6mm
Answer:
20.8mm
Step-by-step explanation:
We know that an octagon has 8 sides, and since this is a regular octagon we can safely say that all sides are equal.
This means all sides are 2.6mm.
So if we run the calculation:
2.6mm × 8 = 20.8mm (Side Length × Number of Sides = Perimeter)

Diego bought 4 boxes of cookies to thank his coaches at the end of the season. Each box had the same number of cookies. A friend brought 1 cookie to add to each box. Now there were 28 cookies in all. What is the unknown amount in the story?
Answer:
there are 24 cookies in the 4 boxes
there are 6 cookies in each box
Step-by-step explanation:
Let x = number of cookies in each box
If there are 4 boxes, the total number of cookies in the four boxes are 4x
If a friend brought 1 cookie to add to each box, the friend brought a total of 4 cookies
4x + 4 = 28
Solving for x
4x = 28 - 4
4x = 24
x = 6
Each box contains 6 cookies and there are 24 cookies in 4 boxes

(d) Find the value of k so that kx + 5y = 10 makes an angle of 30° with y-axis.
Answer: k = -8.66
Step-by-step explanation:
We have the equation:
k*x + 5*y = 10
First, let's rewrite this as a line in the slope-intercept form:
5*y = 10 - k*x
y = 10/5 - (k/5)*x
y = -(k/5)*x + 2
Now, we want to make an angle of 30° with respect to the y-axis.
Then we can think on a triangle rectangle, where we know one angle of 30°, the adjacent cathetus will be equal to the difference between the y-component and the y-intercept, and the opposite cathetus will be equal to the x-component.
To get this, we first need to evaluate the function in one given point, let's use x = 5. (we could use any value of x here, i use 5 because it is easier)
y = -(k/5)*5 + 2
y = -k + 2
then the cathetus of our triangle will be:
adjacent cathetus: (y - 2) = (-k + 2 - 2) = -k
opposite cathetus: x = 5.
Now we know the relation:
Tan(a) = (opposite cathetus)/(adjacent cathetus)
where a = 30°
Then:
Tan(30°) = 5/(-k)
-k = 5/tan(0.577) = 8.66
k = -8.66
This is the value of k that we wanted to find.

Answer:
Option D
Step-by-step explanation:
From the spinner we see there are 5 colours in there.
These are;
Green, Yellow, Red, Purple, Blue.
This means that when it is spinned, there's possibility of getting only one colour per spin.
Since she tosses a coin as well for each spin, there's a possibility of getting either a tail or head per spin.
This means, all possible outcomes will be 5 × 2 = 10 outcomes.
With each colour possibly showing up with either tail or head.
Correct answer is Option D as it has 10 possible outcomes in the correct order.

porfavor: 5(x+9) = 2(x+30)= cuanto es?
Step-by-step explanation:
Primero encontramos el valor de x,
5(x+9) = 2(x+30)
=> 5x + 45 = 2x + 60
=> 5x - 2x = 60 - 45
=> 3x = 15
[tex] = > x = \frac{15}{3} [/tex]
=> x = 5
Como tenemos el valor de x entonces,
LHS = 5(x+9) RHS = 2(x+30)
= 5(5+9) = 2(5+30)
= 5 × 14 = 70. = 2 × 35 = 70
Por tanto, el valor es,
5 (x + 9) = 2 (x + 30) = 70 (Ans)

Which method correctly solves the equation using the distributive property? Negative 0.2 (x minus 4) = negative 1.7
Answer:
4.85
Step-by-step explanation:
Given :
Negative 0.2 (x minus 4) = negative 1.7
-2(x - 4) = - 1.7
-2x + 8 = - 1.7
-2x = - 1.7 - 8
-2x = - 9.7
Divide both sides by - 2
-2x / 2 = - 9.7 / - 2
x = 4.85
A bag contains 15 blue marbles, 5 red marbles, and 11 green marbles. How many blue marbles must be removed
from the 31 marbles in the bag so that the probability of randomly drawing a blue marble is ?
A bag contains 15 blue marbles, 5 red marbles, and 11 green marbles. How many blue marbles must be removed
from the 31 marbles in the bag so that the probability of randomly drawing a blue marble is 1/3?
Answer:
7 blue marbles
Step-by-step explanation:
15 blue
5 red
11 green
Total = 31
Number of Blue marbles that must be removed to obtain a probability of :
P(blue) = 1/3
Probability = required outcome / Total possible outcomes
Let number of blue marble to be removed = x
Number of Blue becomes : 15 - x
Total becomes : 31 - x
P(blue) = 1/3
1/3 = (15 - x) / (31 - x)
1/3 * (31 - x) = 15 - x
(31 - x) / 3 = 15 - x
31 - x = 45 - 3x
-x + 3x = 45 - 31
2x = 14
x = 14 / 2

Find the composition of transformations that map ABCD to EHGF. Reflect over the x axis then translate.
Answer:
[(x + 6), (y + 1)]
Step-by-step explanation:
Vertices of the quadrilateral ABCD are,
A → (-5, 2)
B → (-3, 4)
C → (-2, 4)
D → (-1, 2)
By reflecting the given quadrilateral ABCD across x-axis to form the image quadrilateral A'B'C'D',
Rule for the reflection of a point across x-axis is,
(x, y) → (x , -y)
Coordinates of the image point A' will be,
A(-5, 2) → A'(-5, -2)
From the picture attached, point E is obtained by translation of point A'.
Rule for the translation of a point by h units right and k units up,
A'(x+h, y+k) → E(x', y')
By this rule,
A'(-5 + h, -2 + k) → E(1, -1)
By comparing coordinates of A' and E,
-5 + h = 1
h = 6
-2 + k = -1
k = 1
That means
Rule for the translation will be,
[(x + 6), (y + 1)]
A storekeeper increased the price of hats by `5\%`. A hat was originally priced at `\$15.00`. What is the new cost of the hat?
Answer: $15.75
Step-by-step explanation:
From the question, we are informed that a storekeeper increased the price of hats by 5% and that the hat was originally priced at $15.00.
The new cost of the hat will be:
= $15.00 + (5% × $15.00)
= $15.00 + (5/100 × $15.00)
= $15.00 + (0.05 × $15.00)
= $15.00 + $0.75
= $15.75
The new cost of the hat is $15.75

A cell phone company recently noticed a 26% sales decrease in the month of July compared to June. Let n represent June's
sales. If y represents July's sales, which equation can be used to determine the sales in July?
0 A y = n - 0,26n
OB y = n - 0.26
0 C. y = n + 0,26n
OD. n = y-0.26
22
Answer:
Option A. is correct.
Step-by-step explanation:
Given: A cell phone company recently noticed a [tex]26\%[/tex] sales decrease in the month of July compared to June such that [tex]n[/tex] represent June's sales.
Also, [tex]y[/tex] represents July's sales.
To find: equation that can be used to determine the sales in July
Solution:
June's sales [tex]=n[/tex]
Decrease in sales [tex]=\frac{26}{100}n=0.26n[/tex]
So,
July's sales [tex]=n-0.26n[/tex]
Also,
July's sales [tex]=y[/tex]
Therefore,
[tex]y=n-0.26n[/tex]
So, option A. is correct.
