Answer:
The answer is option A. 117
Step-by-step explanation:
Answer:
take 40 degree as reference angle
using sine rule
let opposite be x
sine 40=opposite/hypotenuse
0.64=x/7
0.64*7=x
4.48=x
Step-by-step explanation:
The system of inequalities is x+y≥250 and 3x+2y≤800.
Step-by-step explanation:
Given,
People to invite = at least 250
At least 250 means that the number can increase from 250.
Cups to be provided = only 800
It means the number cannot exceed 800.
Number of adults = A
Number of children = C
According to given statement;
x+y≥250
3x+2y≤800
The system of inequalities is x+y≥250 and 3x+2y≤800.

Answer:
128 square inches
Step-by-step explanation:
The scale factor for area is the square of the scale factor for side length. The larger octagon has an area of ...
(8/4)²(32 in²) = 4·32 in² = 128 in²
The area of octagon B is 128 square inches.
<h2>Linear equations</h2>
<em>The </em><em>graphical representation</em><em> of a linear equation is a straight line. To solve</em><em> linear equations</em><em>, i</em><em>t is important to keep in mind the following key concepts:</em>
- <em>Maintain the balance of the equation by applying the </em><em>same operations</em><em> to both sides of the equation.</em>
- <em>Clear the variable using like terms.</em>
- <em>Use </em><em>inverse operations</em><em> to rearrange the equation.</em>
<h3>-x + 5 = 1</h3>
We will subtract 5 from both sides.
<h3>−x + 5 - 5 = 1 - 5</h3><h3>−x = -4</h3>
<em>We divide both sides by -1.</em>
<h3>-x/x = -4/-1</h3><h3>x = 4</h3>
Answer: <em>Therefore the solution of the exercise </em><em>-x+5=1,</em><em> is </em><em>x = 4</em><em>. The </em><em>correct option</em><em> is </em><em>"D".</em> ✅
