Two hiking groups made the purchases shown below. What is the cost of each item. GROUP 1: 6 muffins, 12 granola bars, Total=$26.70 GROUP 2: 8 muffins, 15 granola bars, Total=34.00
Answer:
Price of each muffin = $1.25
Price of each granola bar = $1.6
Step-by-step explanation:
Group 1:
6 muffins, 12 granola bars
Total money paid = $26.70
Group 2:
8 muffins, 15 granola bars,
Total money paid = $34.00
To find:
Price of each item?
Solution:
Let the price of one muffin = $[tex]x[/tex]
Let the price of one granola bar = $[tex]y[/tex]
As per group 1, the equation can be written as:
[tex]6x+12y=26.70\\\Rightarrow x+2y=4.45 .... (1)[/tex]
As per group 2, the equation can be written as:
[tex]8x+15y = 34[/tex] .... (2)
Let us use elimination method to solve for [tex]x[/tex] and [tex]y[/tex].
Multiplying equation (1) with 8 and subtracting (2) from it:
[tex]16y-15y = 35.6 - 34\\\Rightarrow y = 1.6[/tex]
Using equation (1):
[tex]x+3.2=4.45\\\Rightarrow x = 1.25[/tex]
Therefore, the answer is:
Price of each muffin = $1.6
Price of each granola bar = $1.25

A circle has a center at the origin and the point (3,4) is on the circle
Answer: 5 units
Step-by-step explanation:
The standard form of equation of circle:
[tex](x-h)^2+(y-k)^2=r^2[/tex] , where (h,k) = center of circle, r= radius.
Given : Center of circle= origin = (0,0) =(h,k)
Point on circle = (3,4)
Put x= 3 , y=4 , h=0 , k=0 , then the equation will become
[tex](3-0)^2+(4-0)^2=r^2\\\\\Rightarrow\ 9+16=r^2\\\\\Rightarrow\ 25=r^2\\\\\Rightarrow\ r=5[/tex]
Hence, the radius is 5 units long.

Graph the system of inequalities presented here on your own paper, then use your graph to answer the following questions: y < 4x – 8 y greater than or equal to -5/2x+5
Part A: Describe the graph of the system, including shading and the types of lines graphed. Provide a description of the solution area. (6 points)
Part B: Is the point (5, -8) included in the solution area for the system? Justify your answer mathematically. (4 points)
Answer:
step by step as explained below
Step-by-step explanation:
A) y<4x-8 is the shade area below the dotted line of y=4x-8
y≥-2/5x+5 is the shade area above the solid line y=-2/5x+5
The solution is the dark color shade area
B) point(5,-8) located within the y<4x-8 area while it's not in the solution area of the system.

4) Name The Angle Pair Represented And Solve For x. *
37°
(6x - 11)
Answer:
x = 8
Step-by-step explanation:
It can be assumed that the attached figure shows the problem and we need to find the value of x.
According to figure, the corresponding angles are equal such that,
(6x - 11) = 37
6x = 37 +11
6x = 48
x = 8
So, the value of x in this case is 8.
Daryl bought 10 adult tickets and 10 children's tickets to a zombie movie for $110. Rick bought 6 adult and 5 children tickets for $63 to the same movie. How much money does each type of ticket cost
Answer:
Adult tickets = $8
Children's tickets = $3
Step-by-step explanation:
Set up a system of equations;
x = adult tickets
y = children's tickets
Daryl's situation;
10x + 10y = 110
Rick's situation;
6x + 5y = 63
Hence the system is;
[tex]\left \{ {{10x+10y=110} \atop {6x+5y=63}} \right.[/tex]
To solve by elimination, one has to multiply one of the systems by a number such that when one adds the two systems, one variable gets eliminated. One is then left with an expression that can be solved for the other variable. Finally, one can substitute the value of the other variable back, to find the value of the first variable.
[tex]\left \{ {{10x+10y=110} \atop {6x+5y=63}} \right.[/tex]
Multiply Rick's situation by (-2)
[tex]\left \{ {{10x+10y=110} \atop {-12x-12y= -126}} \right.[/tex]
Add the two equations;
-2x = -16
Inverse operations;
-2x = -16
/-2 /-2
x = 8
Substitute back in;
10x + 1y = 110
10(8) + 10y = 110
Simplify;
80 + 10y = 110
Inverse operations;
80 + 10y =110
-80 -80
10y = 30
/10 /10
y = 3
x = 8
y = 3
A circle is inscribed in a regular hexagon with side length 12 units. Find the value of x.
The image of the inscribed circle is missing so i have attached it.
Answer:
x = 35
None of the given options are correct.
Thus, Option D is the answer.
Step-by-step explanation:
From the attached image, we can see that there are two lines projecting out of the centre of the circle with one having it's endpoint touching the edge of the hexagon while the other is perpendicular to the centre of a side of the hexagon and labeled x has it's endpoint touching both the circumference and the hexagon side.
Since line labeled x projects from the centre of the circle to the circumference, we can say that the radius is x.
The triangle formed is a right angled triangle with the other part touching only the hexagon as the hypotenuse.
We see the remaining part between the circle and the hexagon of this hypotenuse line given as 2.
Thus, hypotenuse = x + 2
This is because from the centre to the circumference is x as earlier discussed and this hypotenuse line crosses the circumference of the circle before touching the edge of the hexagon.
Using pythagoras theorem, we can find x:
x² + 12² = (x + 2)²
x² + 144 = x² + 4x + 4
x² will cancel out to give;
4x + 4 = 144
4x = 144 - 4
4x = 140
x = 140/4
x = 35
to solve the following equation , 7x - 2 = 12 , which of the choices below is a correct method to find the value of X

What is the total amount owed when $2,500 is borrowed for one year at 6% simple interest?
Answer:
5'506 the answer is 5'506 I because I add 2'500 with 6 and I got that answer
The total amount owed when $2500 is borrowed for one year at 6% simple interest is $2650.
What is Simple Interest?Simple interest is the process of finding the amount of interest if we have some principal value of money. Here a specific interest is charged only for the principal amount.
Formula for calculating the total amount in case of Simple Interest is,
A = p (1 + r t)
where, A is the total amount, p is the principal amount, r is the rate of interest and t is the time period.
Here, p = $2500
r = 6% = 6/100 = 0.06
t = 1 year
So the total amount = 2500 [1 + (0.06 × 1)]
= 2500 [1 + 0.06]
= 2500 × 1.06
= 2650
Hence the total money owed is $2650 when $2500 is borrowed for one year at 6% simple interest.

In the equation a = v/r, if a is plotted against v then what will be the shape of the graph? How about if a is plotted against r?
9514 1404 393
Answer:
a) a straight line
b) a hyperbola
Step-by-step explanation:
a) When a = v/r is plotted against v as the independent variable, it will be a straight line through the origin with a slope of 1/r.
__
b) When a = v/r is plotted against r as the independent variable, it will be a hyperbola with a "constant of proportionality" of v. Here, a is inversely proportional to r.
Maria bought 5 birthday cards from a store. The price of each card was the same. After she bought the cards, her account balance showed a change of -$15.95. What would
have been the change to Marta's account balance had she only bought 1 card from the store?
$3.19
B -$3.19
C $4.50
D -$4.50
Answer:
B

D. n=35 p =0.7
Step-by-step explanation:
The value of the interval (0.4676, 0.9323) is between (0, 1). Then the correct option is D.
What is a normal distribution?It is also called the Gaussian Distribution. It is the most important continuous probability distribution. The curve looks like a bell, so it is also called a bell curve.
The sample size should be greater than 30.
Then
[tex]\mu = p = 0.7\\\\n = 35[/tex]
Then we have the sigma
[tex]\sigma = \sqrt{\dfrac{p(1-p)}{n}}\\\\\sigma = \sqrt{\dfrac{0.7*0.3}{35}}\\\\\sigma = 0.0775[/tex]
Then we have
[tex](\mu - 3 \sigma , \ \mu + 3 \sigma)\\\\(0.7-0.2323, \ 0.7+0.2323)\\\\(0.4676, \ 0.9323)[/tex]
The value of the interval is between (0, 1). Then the correct option is D.

Find the minimum value of
C = x + 3y
subject to the following constraints:
(9x + 2y > 35
x + 3y > 14
X>0
y20
C = [?]
The minimum value of C is 14 because the inequality x + 3y ≥ 14 has the minimum value is 14.
What is inequality?It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than, known as inequality.
We have:
C = x + 3y
Subject to constraints:
9x + 2y > 35
x + 3y ≥ 14
X ≥ 0
y ≥ 0
As we can see in the inequality:
x + 3y ≥ 14
Compare with x + 3y = C
The minimum value of x + 3y is 14
Thus, the minimum value of C is 14 because the inequality x + 3y ≥ 14 has the minimum value is 14.
