Answer:
$1.30
Step-by-step explanation:
As with costs anywhere, you find the total cost by multiplying the unit cost by the number of units. Here, a unit is 1 ounce of tomato sauce. 3.5 units are used in the recipe. The unit cost is given as $0.37 per ounce.
__
cost of sauce = (cost per ounce) × (number of ounces)
= ($0.37) × 3.5 = $1.295
This rounds up to $1.30.
The sauce for one portion costs $1.30.
If it takes 15 minutes to dry your hair with a 1.200 kW hair drier, how much energy is used in drying your hair?
The quantity of energy moved or transformed per unit of time is referred to as power. The amount of energy that is consumed by the hairdryer in 15 minutes will be 0.3 kWh.
What is power?The quantity of energy moved or transformed per unit of time is referred to as power.
Formula: Power = Energy / Time
Units: kW = kWh / hour
The power of electric equipment is given by the formula,
P = E/t
where E is the energy consumed in kWh and t is the time in hours.
Given the power of the hairdryer is 1.200 kW while the time for which it is kept on is 15 minutes, therefore, 0.25 hours. Now, the energy consumed by the dryer in 15 minutes will be,
1.200 kW = E / 0.25
0.3 kWh = E
Hence, the amount of energy that is consumed by the hairdryer in 15 minutes will be 0.3 kWh.

In the figure below, the areas of rectangles A, B, and C are 11, 33, and 75,
respectively. Find the area of rectangle D.
If the areas of rectangles A, B, and C are 11, 33, and 75, respectively. Then the area of the rectangle D will be 25 square units.
What is a rectangle?It is a polygon with four sides. The total interior angle is 360 degrees. A rectangle's opposite sides are parallel and equal, and each angle is 90 degrees. Its diagonals are all the same length and intersect in the center.
In the figure below, the areas of rectangles A, B, and C are 11, 33, and 75, respectively.
Then the area of the rectangle D will be
Let a be the length and b be the width of the rectangle D. Then we have
The ratio of the area of the rectangles will be

Given
m∠MPN = 35°mLP = 130°To find
The value of mMNWe can see MN is intercepted by the angle MPN.
Inscribed angle is half the measure of intercepted arc
m∠MPN = 1/2mMN ⇒ mMN = 2 × m∠MPN = 2 × 35° = 70°The answer is mMN = 70°
Question 2Given
m∠AOB = 40°mED = 60°To find
m∠CODSee the solution with reasons for each line
m∠COD = m∠EOB ⇔ vertical angles are congruentmBD = 180° ⇔ BD is diameter and cuts the circle in halfm∠EOB = mBD - mED ⇔ Angle addition m∠EOB = 180° - 60° = 120° ⇔ SubstitutionSo the answer is m∠COD = 120°

1 AB is tangent to circle O at B. The diagram is not drawn to scale. If AB=12 nd AO=15, what is the length of the radius (r)
Answer:
r = 9 units
Step-by-step explanation:
since AB is a tangent to the circle at B , then ∠ ABO = 90°
so Δ ABO is a right triangle
using Pythagoras' identity in the right triangle
OB² + AB² = AO² , that is
r² + 12² = 15²
r² + 144 = 225 ( subtract 144 from both sides )
r² = 81 ( take square root of both sides )
r = [tex]\sqrt{81}[/tex] = 9

Reset Scarlet bought a coat originally priced at $120. She got a 15% discount. How much did she pay for the coat? $ $
Answer:
$102
Step-by-step explanation:
Reset Scarlet bought a coat originally priced at $120. She got a 15% discount. How much did she pay for the coat?
1. Convert the discount percentage to a decimal:
15/100 = 0.15
2. Multiply the original price by the decimal:
120*0.15 = $18
This is the discount they got.
3. Now, subtract the discounted value from the original price:
120 - 18 = $102
This means that they paid $102 for the coat.
Hope this helps!
Answer:
$102
Step-by-step explanation:
15% of 120
= 15/100×120
0.15×120=$18
therefore, 15% of 120 equal 18
discount= $18
Amount she paid= 120-18= $102

Find the solution of the square root of the quantity of x plus 2 plus 4 equals 6, and determine if it is an extraneous solution. x = 2; extraneous x = 2; not extraneous x = 30; extraneous x = 30; not extraneous
The solution of the equation √x+2 + 4 = 6 is x = 2 and it is not an extraneous solution
How to find the solution of an equation?The solution of the equation can be found as follows;
√x+2 + 4 = 6
subtract 4 from both sides
√x+2 + 4 - 4 = 6 - 4
√x+2 = 2
square both sides
(√x+2)² = 2²
x + 2 = 4
x= 4 - 2
x = 2
Therefore the solution is x = 2 and it is not a extraneous solution.

Write and simplify an expression that represents the sum of the perimeters of the square and the triangle.
A square with side length 6x. A triangle with side lengths 3x, 3x, and x - 2.
Answer:
To solve this question, you simply apply algebraic formulas to geometric relationships.
The perimeter is simply the sum of the lengths of the sides of a shape. However, in this case, there is an "x" involved, so you must add algebraically.
Simply add the length of the sides up.
[3x] + [6x-2] + [x+3] + [4x+1] + [5x-2] = Perimeter
Now, simplify. Since adding is commutative, you can simply put all the variables first and constants next, no matter where they come from within the expression.
3x + 6x + x + 4x + 5x + -2 + 3 + 1 + -2
19x + 0 (-2-2 + 3+1 cancel out)
The perimeter of this pentagon is 19x.
Step-by-step explanation:
two squares have a total area of 208cm square and sum of their perimeter is80cm what are the length of sides of square
The length of the sides of the square are 8 centimetres and 12 centimetres respectively
How to finds area of a square?area = l²
where
l = side lengthTherefore,
x² + y² = 208
How to finds perimeter of a square?perimeter = 4l
4x + 4y = 80 cm
x + y = 20
x = 20 - y
(20 - y)² + y² = 208
y² - 40y + 400 + y² = 208
2y² - 40y + 192
y² - 20y + 96
(y - 12)(y - 8)
Therefore, y = 12 and y = 8
when y = 8
x + 8 = 20
x = 12
when y = 12
x + 12 = 20
x = 8
Therefore, the length of the sides of the square are 12 cm and 8 cm.
