Unit Price = $0.25 per bun

Coupon with the better buy is Coupon B.

Coupon C

Unit price of hamburger meat = [tex]\frac{\text{Price}}{\text{Quantity}}[/tex]

                                                  = [tex]\frac{5.44}{16}[/tex]

                                                  = $0.34 per hamburger

Coupon D

Unit price = [tex]\frac{9.6}{24}[/tex]

                = $0.40 per hamburger

Coupon with better buy is Coupon C.

Step-by-step explanation:

Answer: 17 miles

Step-by-step explanation:

The total cost of the taxi service is the flat free and the total amount that is based on the distance. Let x be this distance. The equation that would best represent the situation is,

1.25 + 0.75x = 14

Solving for x gives the answer of 17. Thus, Henri can afford to travel 17 mile

If Henri has $14.00, the number of miles he can afford to ride in the taxi is 17 miles.

Option (B) is correct.

What is a function?

A technical definition of a function is: a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.

The equation for this situation is as follows:

The taxi service charges a flat fee of $1.25 and $0.75 per mile.

Hence,

let

x = number of miles

y = 0.75x + 1.25

where

y = $14

14  - 1.25 = 0.75x

12.75 = 0.75x

Therefore,

x = 12.75 / 0.75

x= 17

Therefore, the number of miles he can afford is 17 miles.

Answer:

Percent error = 4.29%

Step-by-step explanation:

Percent error can be defined as a measure of the extent to which an experimental value differs from the theoretical value.

Mathematically, it is given by this expression;

[tex] Percent \; error = \frac {experimental \;value - theoretical \; value}{ theoretical \;value} *100[/tex]

Given the following data;

Experimental value = 67

Theoretical value = 70

Substituting into the equation, we have;

[tex] Percent \; error = \frac {67 - 70 }{ 70} *100[/tex]

[tex] Percent \; error = \frac {3}{70} *100[/tex]

[tex] Percent \; error = 0.04286 *100[/tex]

Percent error = 4.29%

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Number of units of orange juice at beginning = 30 units

The number of units purchased = 50 units

Total units = 30 + 50 = 80 units

The number of units at the end = 30 units.

The number of units sold.

= Total units - Units at the end

= 80 - 30

= 50 units.

Thus,

The number of units sold is 50 units.

The length of the base of the following pyramid when the height, angle of elevation is given so it is 158 meters.

Since

The height of the pyramid is 71 meters and the angle of elevation of the base of the pyramid is 42°.

So,

[tex]tan (42) = height \div base\\\\base = height \div tan (42)\\\\base = 71\div tan\ (42)\\\\[/tex]

base = 78.85 m

Now

length of the base pyramid = 2× length of the base of the right triangle

= 2 ×78.85

= 157.7

≈ 158 m

Hence, The length of the base of the following pyramid when the height, angle of elevation is given so it is 158 meters.

Answer:

528 in.²

Step-by-step explanation:

Surface area of the figure = (surface area of the smaller rectangular prism + surface area of the bigger prism) - area of 1 of the base of the smaller rectangular prism

✔️Surface area of the bigger rectangular prism = 2(WL + HL + HW)

= 2(10*12 + 5*12 + 5*10) = 2(120 + 60 + 50)

= 2(230)

Surface area of bigger rectangular prism = 460 in.²

✔️Surface area of the smaller rectangular prism = 2(WL + HL + HW)

= 2(2*2 + 8*2 + 8*2) = 2(4 + 16 + 16)

= 2(36)

Surface area of smaller rectangular prism = 72 in.²

✔️area of 1 of the base of the smaller rectangular prism = L*W = 2*2 = 4 in.²

✅Surface area of the figure = (460 + 72) - 4

= 532 - 4

= 528 in.²
