Answer:
Variable x = cost of cookies
Variable y = cost of brownies
System of equations:
2x + 3y = 9.50
10x + 6y = 20.50
Step-by-step explanation:
Variable x: $ cookies
Variable y: $ brownies
2x + 3y = 9.50
10x + 6y = 20.50
I'm not entirely sure how to explain this one, but my best advice is to just take it step by step when doing these problems. Multiple questions can feel overwhelming so just focus on one question at a time.

An archer releases an arrow with an initial velocity of 20 feet per second at a height of 12 feet. The path the arrow takes can be modeled using the function f(x)=−16x2+20x+12, where f(x) represents the height, in feet, of the arrow and x represents the time the arrow travels in seconds. What is the maximum height, in feet, reached by the arrow? Round your answer to the nearest hundredth if necessary. Do not include units in your answer
Answer: 18.25
Step-by-step explanation:
The arrow reaches its highest point at the y-value of the turning point. Thus, we need to find the maximum quadratic function.
-16x^2+20x+12
We know that the maximum( or minimum) of a parabola is reached at x= -b/(2a)= -20/ 2(-16)= 18.25
Showing that the object will reach a maximum height of 18.25 feet

Write the equation that is parallel to the question: y = -2/3x - 5 and goes through point: (6,-1)
Answer:
y = -2/3x + 3
Step-by-step explanation:
Parallel lines have the same slope so we already know
y = -2/3x + b
Solve for b using the point given
-1=-2/3(6)+b
-1+4=b
b=3
y = -2/3x + 3
please help solve for the area
Answer:
The area of the shape is 126 cm.
Step-by-step explanation:
6 + 3 + 3 = 12 cm, all sides
12 * 12 = 144
3 * 3 = 9 / 2 = 4.5
4.5 * 4 = 18
144 - 18 = 126cm

please this is overdue
Answer:
area is 15 square units
16 units for perimeter
Step-by-step explanation:
perimeter refers to the sum of all of the sides
if the width of this rectangle is 3 squres, and the length of the square is 5 squares then
3+3+5+5 = 16 units for perimeter
for area = length x width
since length = 5 and width = 3 then
5x3=15
so area is 15 square units

which of the following is correct statement about this relation?
Given:
The relation is:
(-3,1),(-2,3),(-1,5),(0,7),(1,9),(2,11)
To find:
The slope and y-intercept for the given relation.
Solution:
Consider any two points from the given relation.
Let the two points are (0,7) and (1,9). So, the slope of the given relation is:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\dfrac{9-7}{1-0}[/tex]
[tex]m=\dfrac{2}{1}[/tex]
[tex]m=2[/tex]
The slope of the given relation is 2.
A point of relation is (0,7). It means the value of relation is 7 at x=0.
So, the y-intercept is 7.
Therefore, the correct option is D.

A triangle has side lengths of 4cm, 6cm, and 11cm. Is the triangle acute, obtuse, or right?
Answer:
No
Step-by-step explanation:
Three segments 4cm, 6cm, and 11cm cannot form a right triangle because if they could, then by Pythagorean theorem, 4^2 + 6^2 = 11^2, which is not true.
Moreover, the three segments cannot form an acute or obtuse triangle because by Triangle Inequality Theorem, the sum of two sides has to be greater than the third side. Here, (4cm + 6cm) is NOT larger than 11cm, and thus you cannot form a triangle.

Answer: $43.20
Step-by-step explanation:
First, we are going to take the price of the box lunch ($6.50)
Now we are going to multiply it by 5
$6.50x5=$32.50
Now we take the total cost of the trip and subtract it by $32.50
$248.50-$32.50=216
now divide 216 by 5
216/5
$43.20
In a class of 29 children, 15 like history and 21 like math. They all like at least one of
the two subjects.
What is the probability that a child chosen at random from the class likes math but
not history?
Answer:
14/29
Step-by-step explanation:
The probability that a child chosen at random from the class likes math but not history is 14/29 or 0.4827.
It is given that the in a class of 29 children, 15 likes history and 21 like math.
It is required to find the probability that a child chosen at random from the class likes math but not history if they all like at least one of the two subjects.
What is the Venn diagram?It is defined as the diagram that shows a logical relation between sets.
The Venn diagram consists of circles to show the logical relation.
We have:
Total students in a class = 29
First we have to find the number of students who likes both subject for this we have draw a Venn diagram shown in the picture.
From the Venn diagram number of students who likes both = 7
And number of students likes only math = 14
Hence, the probability will be:
[tex]p = \frac{14}{29}[/tex] ( because total number of students is 29)
or P = 0.4827 or 48.27%
Thus, the probability that a child chosen at random from the class likes math but not history is 14/29 or 0.4827.
