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.

Best friends Olivia and Sylvia both get weekly allowances. Olivia's and Sylvia's allowances are in the ratio 2 : 3. If Sylvia gets $21 one weeks, how much did Olivia get? Use tape diagram to help organize you thinking.
Answer:
14
Step-by-step explanation:
Olivia would get $14 because one week is equal to 7 days and since the ratio is 2 : 3, we can assume that Oliva gets $14 a week since 7 x 2 = 14.
A 24-sided regular polygon has an angle measure represented as 5g°.

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".

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

Quadrilateral ABCD has the following angle measures:
m∠A = 105°, m∠B = ?°, m∠C = 34°, m∠D = 90°
What is m∠B?
Answer: 131°
Step-by-step explanation:
105°+90°+34° =229°
360°-229°=131°
The measure of ∠B will be 131°.
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°.

Answer: Store A
Step-by-step explanation: Store A = 10 percent off from 70 which is 63 then 10 per cent off from 63 which is 56.7 which is $56.70 dollars
Store B - 15 percent off from 80 which is 68 then 10 percent off that which is 61.2 which is $61.20
Store C - 10 percent off from 90 which is 81 and then 20 dollars of 81 which is $61
Answer:
Store A
Step-by-step explanation:
Store A: $70 take off 10% = $63
$63 - 10% = $56.7
