A. $0.50 per cookie, $1.25 per brownie
B. $0.75 per cookie, $1.50 per brownie
C. $0.25 per cookie, $1.00 per brownie
D. $1.00 per cookie, $1.00 per brownie
Answer:
The cost of the $0.5 per cookies and $1.25 per brownie.
Option (A) is correct.
Step-by-step explanation:
Let us assume that the cost of the cookies =x
Let us assume that the cost of the brownie = y
As given
Sara is selling cookies and brownies as a fundraiser for the school band.
She charges $2.25 for two cookies and one brownie.
Than the equation becomes
2x + y = 2.25
She charges $5.75 for four cookies and three brownies.
4x + 3y = 5.75
Than two equation are
2x + y = 2.25 and 4x + 3y = 5.75
Multiply 2x + y = 2.25 by 3 and subtracted from 4x + 3y = 5.75
4x - 6x + 3y - 3y = 5.75 - 6.75
-2x = - 1
2x = 1
[tex]x = \frac{1}{2}[/tex]
x = $0.5
Put in the equation 2x + y = 2.25
2 × 0.5 + y = 2.25
1 + y = 2.25
y = 2.25 - 1
y = $1.25
Therefore the cost of the $0.5 per cookies and $1.25 per brownie.
Option (A) is correct.
Answer:
A is correct
Step-by-step explanation:
What is the equation of this line? y=12x−3 y=−12x−3 y=−2x−3 y=2x−3 Number graph ranging from negative 5 to 5 on both the x and y axis. A line passes through the point begin ordered pair 0 comma negative 3 end ordered pair and the point begin ordered pair 4 comma negative 1 end ordered pair
We are given that
A line passes through two points as
(0,-3) and (4,-1)
[tex](x_1,y_1)=(0,-3)[/tex]
[tex]x_1=0,y_1=-3[/tex]
[tex](x_2,y_2)=(4,-1)[/tex]
[tex]x_2=4,y_2=-1[/tex]
Firstly, we can find slope
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
now, we can plug values
[tex]m=\frac{-1+3}{4-0}[/tex]
[tex]m=\frac{2}{4}[/tex]
[tex]m=\frac{1}{2}[/tex]
now, we can use point slope form of line
[tex]y-y_1=m(x-x_1)[/tex]
we can plug values
[tex]y+3=\frac{1}{2} (x-0)[/tex]
[tex]y+3=\frac{1}{2}x[/tex]
[tex]y=\frac{1}{2}x-3[/tex]
so, the equation of line is
[tex]y=\frac{1}{2}x-3[/tex]...............Answer

find A common denominator of 1/6 and 1/9. rewrite the pair of fractions using common denominator.
Answer:
the pair would be 3/18 and 2/18
The pair of fractions, 1/6 and 1/9, can be rewritten as 3/18 and 2/18, respectively, using the common denominator of 18.
We have,
The prime factorization of 6 is 2 * 3.
The prime factorization of 9 is 3 * 3.
To find the LCM, take the highest power of each prime factor:
LCM = 2 * 3 * 3 = 18
The common denominator for 1/6 and 1/9 is 18.
To rewrite the fractions using the common denominator of 18:
1/6 = (1/6) * (3/3) = 3/18
1/9 = (1/9) * (2/2) = 2/18
Thus,
The pair of fractions, 1/6 and 1/9, can be rewritten as 3/18 and 2/18, respectively, using the common denominator of 18.

A ladder is leaning against the side of a building. The building and the ground form a right angle. How high on the building will the ladder touch if the ladder is 10 ft long and the base of the ladder is 6 ft from the base of the building?
The height of wall where the ladder touches it is 8 ft.
Given that, a ladder is leaned against a wall, the building and the ground form a right angle, we need to find that how high on the building will the ladder touch,
So, here using the Pythagoras theorem,
Formula =
a²+b² = c², a, b and c are the sides of a right triangle,
Here, c = 10 ft, b = 6 ft we need to find the a,
a²+6² = 10²
a² = 100-36
a² = 64
a = 8
Hence, the height of the wall where the ladder touches it is 8 ft.

The volume of a rectangular prism can be computed using the formula V = lwh. What is the height of a prism that has a volume of 2376 cubic centimeters, a length of 18 centimeters, and a width of 11 centimeters
Answer:
The height of the prism is approximately [tex]\(12\)[/tex] centimeters.
Explanation:
To find the height ([tex]\(h\)[/tex]) of the prism, we can rearrange the formula for volume to solve for [tex]\(h\):[/tex]
[tex]\[ V = lwh \][/tex]
We can rewrite this formula to solve for [tex]\(h\):[/tex]
[tex]\[ h = \frac{V}{lw} \][/tex]
Given:
- Volume ([tex]\(V\)[/tex]) = 2376 cubic centimeters
- Length ([tex]\(l\)[/tex]) = 18 centimeters
- Width ([tex]\(w\)[/tex]) = 11 centimeters
Substitute these values into the formula to find the height:
[tex]\[ h = \frac{2376}{18 \times 11} \][/tex]
[tex]\[ h = \frac{2376}{198} \][/tex]
[tex]\[ h \approx 12 \text{ centimeters} \][/tex]
So, the height of the prism is approximately [tex]\(12\)[/tex] centimeters.

Jenna says that no row or column contains products with only odd numbers do you agree explain.
Jenna's claim that no row or column contains products with only odd numbers is wrong. A counterexample can be found by examining a matrix.
Explanation:Jenna claims that no row or column contains products with only odd numbers. Let's examine whether this statement is true or not. Let's consider a matrix and see if we can find a row or column that contains products with only odd numbers.
For example, let's take the following matrix:
1 2
3 4
In this matrix, we can see that the 1st row contains the product 2 and the 2nd row contains the product 12 which are both even numbers.
So, Jenna's statement is not true as we have found a row that contains products with only even numbers.

Which one of the following is an arithmetic sequence?
A. −2, 1, 4, 7, 10, . . .
B. 2, 3, 5, 7, 11, 13, 17, . . .
C. 5, 0, −1, −3, −7, . . .
D. .35, .5, .85, 1.1, 1.22, . . .
Final answer:
Option A (-2, 1, 4, 7, 10, ...) is an arithmetic sequence because there is a consistent common difference of +3 between each term. The other options do not show a constant difference between terms, so they are not arithmetic sequences.
Explanation:
To determine which of the sequences is an arithmetic sequence, we look for a constant difference between successive terms. An arithmetic sequence is a sequence of numbers in which each term after the first is found by adding a constant, known as the common difference, to the previous term.
A. −2, 1, 4, 7, 10, . . . - The difference between terms is consistently +3, so this is an arithmetic sequence.
B. 2, 3, 5, 7, 11, 13, 17, . . . - The sequence consists of prime numbers and does not have a consistent difference. Not an arithmetic sequence.
C. 5, 0, −1, −3, −7, . . . - The differences between terms here change; they are not constant. Not an arithmetic sequence.
D. .35, .5, .85, 1.1, 1.22, . . . - The differences between terms do not remain the same, so it's not an arithmetic sequence.
Our answer is A: −2, 1, 4, 7, 10, . . .. This is the only arithmetic sequence from the given options as it has a consistent common difference of +3 between each term.
A turtle fell to the bottom of a deep well. The turtle climbed up 2 meters on the first day, but slipped back 1 meter as he rested. The second day, the turtle climbed double the distance of the previous day, but slipped and lost ½ of the day’s climbed distance as he rested. This pattern continued until the end of the fourth day, when the turtle realized he was halfway to the top of the well. How deep was the well?
Analyzing the climbing pattern of the turtle for four days shows that it climbed 15 meters which is halfway to the top, thus the entire depth of the well is 30 meters.
The question asks for the determination of the depth of a well based on a pattern observed in a turtle's attempt to climb out of it. To do this, we need to analyze the climbing and slipping pattern for four days until the turtle is halfway out of the well.
On the first day, the turtle climbed up 2 meters and slipped back 1 meter, netting a 1 meter gain. On the second day, the distance climbed is double that of the previous day (2 meters x 2 = 4 meters), but the turtle loses half of it while resting, which means a gain of 2 meters for the second day (4 meters / 2 = 2 meters). Following the pattern:
Day 1: +2 - 1 = +1 meterDay 2: +(2 x 2) - (4 / 2) = +2 metersDay 3: +(4 x 2) - (8 / 2) = +4 metersDay 4: +(8 x 2) - (16 / 2) = +8 metersThe total distance climbed after four days is 1 + 2 + 4 + 8 = 15 meters. Since this is halfway to the top, the entire depth of the well would be 15 meters imes 2 = 30 meters.
