Dana saved 450 for food for her upcoming vacation. The breakfast was included with their hotel, but lunch and dinner are not. Wh
zzz [600]

Answer:

10d + 40r \leq 450

Step-by-step explanation:

Given

Savings = 450

Dana\ Cooks, d = 10

Restaurant, r = 40

Required

Represent this as an inequality

When Dana cooks;

Cost\ per\ meal = 10

Cost\ per\ d\ meals = d * 10

Cost\ per\ d\ meals = 10d

At Restaurant

Cost\ per\ meal = 40

Cost\ per\ r\ meals = 40 * r

Cost\ per\ r\ meals = 40 r

Add these two results:

Result = 10d + 40r

<em>To represent as an inequality, the above result must be less than or equal to Dana's total savings</em>

i.e.

10d + 40r \leq 450

morpeh [17]

Answer:

The correct option is;

It has no reflectional symmetry

Step-by-step explanation:

Reflectional symmetry is one such that a line can be drawn across a shape or figure and the shape or figure on either side of the line is the equivalent of the reflection image obtained from a mirror

Lines of reflectional symmetry can be found in squares, circles, and triangles

The characteristics of the object that has line of reflection symmetry remains the same across the line of symmetry

Two dimensional objects have lines of symmetry while three dimensional objects have planes of symmetry.
