I need you someone to solve this and show their work. Tell me why the answer is 4.
Answer:
x = 4
Step-by-step explanation:
You begin by making what is inside the brackets = 0. In other words you will somehow get 0 * brackets + 3 = 3
x - 4 = 0
x - 4 + 4 = 0 + 4
x = 4. When you make x = 4, the inside of the brackets = 0
1/2 * 0 = 0
So you are left with
3 = 0 + 3
and x has been made = 4
Do what's in the brackets before anything else.

HI Please try to answer it and reply below: Find the cost of fencing a square park of side 125m at a rate of Rs. 15 per meter Please comment on the answer to this question below Also Please send me friend requests Thanks Regards Super Cool Indian
Answer: Rs7500
Step-by-step explanation:
First and foremost, we should realise that a square has 4 sides. Therefore, the total sides of the square will be:
= 125m × 4
= 500m
Since the rate is Rs15 per meter, then the cost of the fencing will be:
= 500 × Rs15
= Rs7500
Whiskers the cat weighs 2 and 2/3 kg. Piglio weighs 4 kg.
How many times as heavy as Whiskers is Piglio?
Answer:
1 1/2kg
Step-by-step explanation:
So we have to do the inverse operation thing, so our equation is:
4 ÷ 2 2/3 = 1 1/2
So Whiskers is 1 1/2 times as heavy as Piglio
Answer:
Whiskers is two-third times as heavy as piglio is

What is the exact value of sin(105°)?
ANSWER - D) sqrt(2 + sqrt3)/2
Answer:
[tex]\sin 105^{\circ} = \frac{\sqrt{6}+\sqrt {2}}{4}[/tex]
Step-by-step explanation:
We can use the following trigonometrical identity:
[tex]\sin (\alpha - \beta) = \sin \alpha \cdot \cos \beta - \cos \alpha \cdot \sin \beta[/tex] (1)
Where [tex]\alpha[/tex], [tex]\beta[/tex] are angles, measured in sexagesimal degrees.
If we know that [tex]\alpha = 135^{\circ}[/tex] and [tex]\beta = 30^{\circ}[/tex], then the value of the given function is:
[tex]\sin 105^{\circ} = \sin 135^{\circ}\cdot \cos 30^{\circ} - \cos 135^{\circ}\cdot \sin 30^{\circ}[/tex]
[tex]\sin 105^{\circ} = \left(\frac{\sqrt{2}}{2} \right)\cdot \left(\frac{\sqrt{3}}{2}\right)-\left(-\frac{\sqrt{2}}{2} \right)\cdot \left(\frac{1}{2}\right)[/tex]
[tex]\sin 105^{\circ} = \frac{\sqrt{6}}{4}+\frac{\sqrt{2}}{4}[/tex]
[tex]\sin 105^{\circ} = \sqrt{\frac{6}{16} }+\sqrt{\frac{2}{16} }[/tex]
[tex]\sin 105^{\circ} = \sqrt{\frac{3}{8} }+\sqrt{\frac{1}{8} }[/tex]
[tex]\sin 105^{\circ} = \frac{\sqrt{3}+1}{2\cdot \sqrt{2}}[/tex]
[tex]\sin 105^{\circ} = \frac{\sqrt{6}+\sqrt {2}}{4}[/tex]

At dinner, the meal cost $22 and a sales tax of $1.87 was added to the bill. "What would be the total amount if the meal cost $80?" *
Answer:
$86.8
Step-by-step explanation:
Step one:
Given data
At dinner, the meal cost $22 and a sales tax of $1.87
let us find what percent $1.87 to the cost of the meal
= 1.87/22*100
=0.085*100
=8.5%
Hence the sale tax is 8.5%
Step two:
if the cost is now $80
the sale tax will cost
=8.5/100*80
=0.085*80
=$6.8
The total will be
=80+6.8
=$86.8

Using the figure above, what are the measures of the 3 angles in triangle DEF? PLS HURRY! THANKS
Answer:
F= 34 degrees (alternate angles are equal)
To find D
we first have to find the angles at AB
B =180- 165 (sum of angles on a straight line = 180°)
therefore B = 15°(we'll use this to find the angle at E)
A=34 (from the diagram)
so,
D = 180- (15 + 34) [sum of angles in a triangle = 180°]
D = 131°
E=15° (alternate angles are equal )
