1. Solve the equation. Round to the nearest hundredth.
Answer:
10.31
Step-by-step explanation:
If 0.776 = 8/x and we want to solve for x, invert both sides of the equation to obtain
x/8 = 1/0.776, which becomes
x = 8/0.776 = 10.31 (to the nearest hundredth)
One side of each pentagon lies along a side of the octagon.
AB is a side of the octagon.
AC is a side of one of the pentagons.
BC is a side of the other pentagon.
Work out the size of angle y.
Show your working clearly.
Answer:
The size of angle y is 126°
Step-by-step explanation:
From the diagram of the regular polygons, we have;
One side of each pentagon lies along a side of the octagon
The interior angle of the octagon > The interior angle of the pentagon
Each interior angle of a regular pentagon = 108°
Each interior angle of a regular octagon = 135°
Therefore, ∠ABC = 135° - 108° = 27°
Similarly, ∠BAC = 135° - 108° = 27°
Therefore, by triangle the angle sum theorem, we have;
∠y = ∠ACB = 180° - ∠BAC - ∠ABC = 180° - 27° - 27° = 126°
The size of angle y, ∠y = 126°.

Help! I need some explanation here!
Answer:
So its is pretty straight forward (answer at the bottom)
First of all 2 sides of a parrleogram are the dame and the other 2 are different from the first but the opposites are the same
So lets start with The distance from home to bank
x+9 is the distance since its the opposite
Now the other side is 2x+1
The third side is x+9
the fourth side is x+5, it is different from 2x+1 but its just written differently.
Now add them all up
2x+1+x+9+x+5+x+9=
5x+24
So the amount fo meters are 5x+24
The distance covered by Amaia is 5x+24 meters.
What is a parallelogram?A parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure.
Given that, Amaia walks out and covers a distance in a shape of parallelogram,
Therefore, the opposite sides will be equal,
To find the distance covered we will find the perimeter of the parallelogrammical way,
P = x+9+x+9+x+5+2x+1
P = 5x+24
Hence, the distance covered by Amaia is 5x+24 meters.

John wrote that 5+5=10. Then he wrote that 5+5+n=10+n. Are the equations John wrote equivalent? Explain (in your solution justify by stating what property of equality he used).
Answer:
They are equivalent
Step-by-step explanation:
n would equal the same, and 10 and 5+5 equal the same. Therefore, whatever n is, they will be equal no matter what. Unless you subtract the n from one side and add on the other.

A meal costs $30 before tax and tip. There is a 7% sales tax. After the tax, a 20% tip is added. What is the total after tax and tip?
Answer:
The total is $38.1
Step-by-step explanation:
The tax is $2.1, The tip is $6.
Percentage is the part of the whole expressed in the fraction of hundred.
The total cost of the meal after the tip and tax is $38.1.
What is percentage of a number?
Percentage of a number or ratio expressed in the form of fraction of hundred.
Given information-
The total cost of meal before tax and tip is $30.
The total sales tax is 7%.
The tip added to the cost of meal is 20%.
As, the total sales tax is 7% and cost of the meal is $30. Thus the total sales tax amount is,
[tex]s_t=30\times\dfrac{7}{100} \\s_t=2.1[/tex]
Thus the amount of sales tax is 2.1.
As the the tip added to the cost of meal is 20% and the cost of the meal is 32.1 after the tax. Thus the amount of meal after the 20 % tip is,
[tex]s_t=30\times\dfrac{20}{100} \\s_t=6.00[/tex]
The amount of the tip of the meal after the tax is $6.00.
The cost of meal after the tip and tax is,
[tex]C=30+2.1+6\\C=38.1[/tex]
Hence the total cost of the meal after the tip and tax is $38.1.

A.144kr7
B.12kr7
C.12k2r4

2[tex]\sqrt{6}[/tex]
Step-by-step explanation:
Using the rule of radicals
[tex]\sqrt{a}[/tex] × [tex]\sqrt{b}[/tex] ⇔ [tex]\sqrt{ab}[/tex]
Simplifying the radicals
[tex]\sqrt{96}[/tex]
= [tex]\sqrt{16(6)}[/tex]
= [tex]\sqrt{16}[/tex] × [tex]\sqrt{6}[/tex] = 4[tex]\sqrt{6}[/tex]
[tex]\sqrt{24}[/tex]
= [tex]\sqrt{4(6)}[/tex]

Thus
[tex]\sqrt{96}[/tex] + 2[tex]\sqrt{6}[/tex] - 2[tex]\sqrt{24}[/tex]

Suppose we have a right triangle with legs of length a and b and hypotenuse of length c. Suppose b=3 and c=5. Then a= , For the opposing angles, we have sin(A)= , cos(A)= , and tan(A)= .
Answer:
Length of right-angle triangle 'a' = 4
b)
[tex]sin(A) = \frac{opposite side}{Hypotenuse} = \frac{a}{c} = \frac{4}{5}[/tex]
[tex]cos(A) = \frac{Adjacent side}{Hypotenuse} = \frac{b}{c} = \frac{3}{5}[/tex]
[tex]tan(A) = \frac{opposite side}{Adjacent side} = \frac{a}{b} = \frac{4}{3}[/tex]
Step-by-step explanation:
Step(i):-
Given b = 3 and hypotenuse c = 5
Given ΔABC is a right angle triangle
By using pythagoras theorem
c² = a² + b²
⇒ a² = c² - b²
⇒ a² = 5²-3²
=25 - 9
a² = 16
⇒ a = √16 = 4
The sides of right angle triangle a = 4 ,b = 3 and c = 5
Step(ii):-
[tex]sin(A) = \frac{opposite side}{Hypotenuse} = \frac{a}{c} = \frac{4}{5}[/tex]
[tex]cos(A) = \frac{Adjacent side}{Hypotenuse} = \frac{b}{c} = \frac{3}{5}[/tex]
[tex]tan(A) = \frac{opposite side}{Adjacent side} = \frac{a}{b} = \frac{4}{3}[/tex]
