Answer:
C
Step-by-step explanation:
The area is calculated as width × length , that is
[tex]\frac{50\sqrt{3} }{\sqrt{2} }[/tex] × [tex]\frac{80\sqrt{5} }{\sqrt{3} }[/tex] ( cancel [tex]\sqrt{3}[/tex] on numerator/ denominator
= [tex]\frac{50}{\sqrt{2} }[/tex] × 80[tex]\sqrt{5}[/tex]
= [tex]\frac{4000\sqrt{5} }{\sqrt{2} }[/tex]
To rationalise the denominator multiply numerator/denominator by [tex]\sqrt{2}[/tex]
= [tex]\frac{4000\sqrt{6} }{\sqrt{2} }[/tex] × [tex]\frac{\sqrt{2} }{\sqrt{2} }[/tex]
= [tex]\frac{4000\sqrt{10} }{2}[/tex]
= 2000[tex]\sqrt{10}[/tex] → C
Answer: The answer is C!

Alice is standing on the roof of a 150 ft building. She looks down at an angle of depression of 15 degree and sees her friend bianca. How far away from the building is bianca
Answers
Answer:
559.70 ft
Step-by-step explanation:
Let D be the distance between building and Bianca.
Height of building H = 150 ft
Let there be a triangle ABC where, AC = height of building H= 150ft, AB = distance between Alice and Bianca and BC = D and therefore, ∠ABC = 15°.
Now in Triangle ABC , tanB = AC/BC
therefore, tan15° = 150/D
D = 150/tan15° = 559.70 ft
Therefore, the distance between building and Bianca D = 559.70 ft

Kimberly wants to get a backpack that cost $35 it is now on sale for 15% off she has to pay 7.5% sales tax what is the sales price of the backpack
Answers
Answer:
$44.26
Step-by-step explanation:
The computation of the sales price is shown below:
Its cost is $35
There is a sale off i.e. 15% off
And, the sales tax rate is 7.5%
SO, the sale price is
= $35 × 100 ÷ 85 + ($35 × 100 ÷ 85) × 7.5%
= $41.17 + $41.17 × 7.5%
= $41.17 + $3.09
= $44.26
Hence, the sales price is $44.26

23/50 simplified in fraction form
Answers
The simplified fraction is 23/50.
We have,
To simplify the fraction 23/50, find the greatest common divisor (GCD) of the numerator (23) and the denominator (50), and then divide both the numerator and the denominator by the GCD.
The GCD of 23 and 50 is 1, as they have no common factors other than 1.
Now, divide both the numerator and the denominator by 1:
23 ÷ 1 = 23
50 ÷ 1 = 50
Thus,
The simplified fraction is 23/50.

Answers
Answer:
The opposite sides of a parallelogram are congruent, then
19x - 9 = 13x + 15 ( subtract 13x from both sides )
6x - 9 = 15 ( add 9 to both sides )
6x = 24 ( divide both sides by 6 )

Consecutive angles are supplementary, sum to 180° , that is
10y - 37 + 4y + 7 = 180
14y - 30 = 180 ( add 30 to both sides )
14y = 210 ( divide both sides by 14 )
y = 15
Then
∠ R = 10y - 37 = 10(15) - 37 = 150 - 37 = 113°
Then
∠ P = 113° ( opposite angles are congruent )

Please help me. Pleaseeeeeeee
Answers
Answer:
Step-by-step explanation:
To solve for the measure of Angle N with the given side lengths, you need to find the inverse tangent (tan^-1). You use the tangent because you have the opposite and adjacent side lengths of the angle.
The step by step solution:
tan(<N)=1.7/6.7
<N=tan(^-1)1.7/6.7
<N=14 degrees

Type of quadrilateral are:
Trapezoid.Rectangle.Parallelogram.Rhombus.Square.Kite.A figure has vertices A = (0, 0), B = (1, 3), C = (0, 4), and D = (-1, 1).
The distance between AB is given as,
