Malia has $10 to spend at the fall carnival. She decides to order an ice cream cone for herself and one for her sister.
a. If the cost of each ice cream cone is $2.35, how much will she spend on the ice cream cones? Write an equation and solve.
b. How much change will Malia receive? Write an equation and solve.
Answer:
Malia's allowance changed from $10.00 to $(10 - 2x) after buying ice cream cones.
Step-by-step explanation:
We are given the following information:
Malia's allowance to spend at carnival = $10.00
Ice cream ordered by her = 2
Let x dollars be the cost of one ice cream cone.
Total money spent on ice creams =
Formula:
change in Malia's allowance = total allowance - money spent on ice cream cones = 10 - 2x
Thus, Malia's allowance changed from $10.00 to $() after buying ice cream cones.

What is mean by Rectangle?
A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.
Given that;
The angle of the quadrilateral are;
m ∠A = 105°, m ∠B = ?°, m ∠C = 34°, m ∠D = 90°
Now,
Since, The sum of all the angles of the quadrilateral are 360°.
Let the measure of ∠B = x
So, We can formulate;
⇒ m ∠A + m ∠B + m ∠C + m ∠D = 360°
Substitute all the values we get;
⇒ 105° + x + 34° + 90° = 360°
Solve for x as;
⇒ x + 229 = 360
⇒ x = 360 - 229
⇒ x = 131°
Thus, The measure of ∠B will be 131°.

4.5 L of orange juice is needed to add to 18 L of pineapple juice to make the fruit juice recipe with the ratio of 2 parts orange juice to 8 parts pineapple juice. The correct option is B.
What is an expression?An expression is a grouping of one or more mathematical or logical operators, operands (values, variables, or other expressions), and brackets in mathematics and computer programming that denote a computation that can be evaluated to generate a value.
The correct proportion that can be used to find the amount of orange juice, j, that is needed to add to 18 L of pineapple juice is:
2/8 = j/18
This proportion is based on the ratio of 2 parts orange juice to 8 parts pineapple juice in the recipe. We can use this proportion to find the amount of orange juice, j, that is needed to add to 18 L of pineapple juice by cross-multiplying:
2/8 = j/18
2 × 18 = 8 × j
36 = 8j
j = 4.5
Therefore, 4.5 L of orange juice is needed to add to 18 L of pineapple juice to make the fruit juice recipe with the ratio of 2 parts orange juice to 8 parts pineapple juice.

Determine the distance between the points (−2, −4) and (−7, −12).
square root of 337 units
square root of 109 units
square root of 89 units
square root of 13 units
Answer: square root of 89 units i think so
Step-by-step explanation:
The distance between the points (−2, −4) and (−7, −12) is √89 units.
Among the given options, the correct answer is "square root of 89 units."
To determine the distance between the points (−2, −4) and (−7, −12), we can use the distance formula. The distance formula calculates the distance between two points (x₁, y₁) and (x₂, y₂) in a Cartesian coordinate system.
The distance formula is given by:
d = √((x₂ - x₁)² + (y₂ - y₁)²)
Let's substitute the coordinates of the given points into the formula:
d = √((-7 - (-2))² + (-12 - (-4))²)
= √((-7 + 2)² + (-12 + 4)²)
= √((-5)² + (-8)²)
= √(25 + 64)
= √89

The sum of all interior angles inside an "n" number of sides polygon is 180(n - 2) thus the measure of g will be 33 so option (A) is correct.
What is an angle?The angle is the measurement of the angular distance for example for linear motion we have a meter inch but for angular rotation, we don't have the measurement so the angle is useful to measure the angular rotation.
The sum of all interior angles inside an "n" number of sides polygon is 180(n - 2).
Given that a polygon with a number of sides is 24.
And the measure of one angle is 5g.
Sum of all angles = 24(5g).
24(5g) = 180(n - 2)
120g = 180(24 - 2)
g = (18/12)(22)
g = 33
Hence "The sum of all interior angles inside an "n" number of sides polygon is 180(n - 2) thus the measure of g will be 33".
