Mallory is on a budget and wants to determine which cereal is a better buy. A 10-ounce box of Cereal A costs $2.70 and a 13-ounce box of Cereal B costs $3.64. The store is selling each cereal in 15 ounce boxes. Which cereal is cheaper and by how much?
Answer:
Cereal A is cheaper by $0.15
Step-by-step explanation:
Cost of a 10-ounce box of Cereal A = $2.70
So,
Cost of a 1-ounce box of Cereal A = [tex]\frac{2.70}{10}=\$0.27[/tex]
Cost of a 15-ounce box of Cereal A = [tex]0.27(15)=\$4.05[/tex]
Also,
Cost of a 13-ounce box of Cereal B = $3.64
So,
Cost of a 1-ounce box of Cereal B = [tex]\frac{3.64}{13}=\$0.28[/tex]
Cost of a 15-ounce box of Cereal B = [tex]=0.28(15)=\$4.2[/tex]
Here,
Cost of a 15-ounce box of Cereal B - Cost of a 15-ounce box of Cereal A = [tex]4.2-4.05=\$0.15[/tex]
Therefore,
Cereal A is cheaper by $0.15

What is the the y-intercept and x-intercept of the line.
4x - 4y= 36
Answer:
x-intercept: (9,0)
y-intercept: (0,-9)
Step-by-step explanation:
The x-intercept and y-intercept is the point at which a line intersects the x-axis and y-axis, respectively. All points on the x-axis have a y-value of 0, while all points on the y-axis have an x-value of 0. Thus, to find the x and y intercepts, substitute 0 for one of the variables in the equation, then solve for the other.
1) To find the x-intercept, substitute 0 for y. Then, isolate x.
[tex]4x-4(0)=36\\4x-0=36\\4x = 36\\x = 9[/tex]
So, the x-intercept must be (9,0).
2) To find the y-intercept, substitute 0 for x. Then, isolate y.
[tex]4(0)-4y = 36\\0-4y = 36\\-4y = 36\\y = -9[/tex]
So, the y-intercept must be (0,-9).
Which expression represents the distance between the points (a,0) and (0,5) on a coordinate grid?
o 5
127+5
127 +25
o via-2572
o Via-532
Answer:
b
Step-by-step explanation:
The expression that represents the distance between the points (a, 0) and (0, 5) on a coordinate grid is √(a² + 25).
What is the distance between two points of a line?The distance between two points of a line is given as:
Distance = [tex]\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]
We have,
The distance formula can be used to find the distance between two points on a coordinate grid.
The distance between the points (a, 0) and (0, 5) is given by:
√((a - 0)² + (0 - 5)²)
Simplifying the expression gives:
√(a² + 25)
Thus,
The expression that represents the distance between the points (a, 0) and (0, 5) on a coordinate grid is √(a² + 25).

The point P=\left(-\frac{\sqrt{33}}{7},\,\, y\right)P=(− 7 33 ,y) lies on the unit circle shown below. What is the value of yy in simplest form?
Answer:
y = √-1040/7
Step-by-step explanation:
The equation of a unit circle is expressed as;
x²+y² = 1
Given the coordinate of P = (-33/7, y)
Substitute the coordinate into the give expression and find y;
(-33/7)²+y² = 1
Expand
y² = 1-(-33/7)²
According to difference of two square
y² = (1+(-33/7))1-(-33/7))
y² = (1-33/7)(1+33/7)
y² = -26/7(40/7)
y² = -1040/49
y= √-1040/49
y = √-1040/√49
y = √-1040/7
Hence the value of y is y = √-1040/7

Find the diagram attached. You can see from the diagram that both angles are vertically opposite angles and vertically opposite angles are equal.
Hence 2x+13 = 3x-3
Collect like terms
2x-3x = -3-13
-x = -16
Multiply both sides by -1
-1(-x) = -1(-16)
x = 16
Hence the value of x is 16
Answer:
x=16 hope this helps!
