Answer:
30 cubic yards
Step-by-step explanation:
You will multiply 13 by two because there is two sides of 13ft
13 x 2 = 26
Then do the same thing with 31, so 31 multiply by 2
31 x 2 = 62
After that add 62 and 26
62+26=88
Then divide 88 by 3
88÷3=29.9
after that you will round 29.9 by the nearest 10 which is 30
A retired math teacher takes his grandson shopping. He tells his grandson that they can spend x
dollars and x - 72.6 = 11. What operation does the grandson need to use to find how much money
they can spend?
Answer:
Addition, 83.6
Step-by-step explanation:
x - 72.6 = 11, x = 83.6
The grandson must add 72.6 to both sides to solve for x.

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]

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.

Find the perimeter and area of a rectangle with length (6) and width (x + 2).
Answer:
The perimeter of a rectangle is: P = 2x+16
The area of a rectangle is: A = 6x+12.
Step-by-step explanation:
Given
The length of a rectangle = l = 6
The width of a rectangle = w = (x+2)
To determine
The perimeter of a rectangle = P
The area of a rectangle = A
Determining the Perimeter of a rectangle
The perimeter of a rectangle can be determined using the formula
P = 2(l+w)
substitute l = 6 and w = (x+2)
P = 2(6+x+2)
P = 2(8+x)
P = 2x+16
Therefore, the perimeter of a rectangle is: P = 2x+16
Determining the Area of a rectangle
The Area of a rectangle can be determined using the formula
A = lw
substitute l = 6 and w = (x+2)
A = (6)(x+2)
A = 6x+12
Therefore, the area of a rectangle is: A = 6x+12.

Write the equation of the line that passes through the points (3,5) and (-1,1). Put
your answer in fully reduced point-slope form, unless it is a vertical or horizontal line.
Given:
A line passes through the two points (3,5) and (-1,1).
To find:
The equation of the line in fully reduced point-slope form.
Solution:
If a line passes through two points, then the point slope form of the line is
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
The line passes through the two points (3,5) and (-1,1). So, the point slope form of the line is
[tex]y-5=\dfrac{1-5}{-1-3}(x-3)[/tex]
[tex]y-5=\dfrac{-4}{-4}(x-3)[/tex]
[tex]y-5=1(x-3)[/tex]
Therefore, the point slope form of the line in fully reduced form is [tex]y-5=1(x-3)[/tex], here 1 is the slope of the line.

Ocsar and his little brother made up a game using coins. They flip the coin towards a cup and receive points for every one that makes it in. Oscar starts with 20 points, and his little brother starts with 18 points. Oscar gets 2 points for every successful shot, and his brother, since he is younger, gets 3 points for each successful shot. Eventually, the brother will have a tied score in the game. How many additional shots will each brother have made? How many points will they both have?
they both would have 24
they both would have 2 successful shots. they would mean that the older brother added 4 point to his score and the younger brother would have added 6 to his score
Solve 4x + 2 = 20 klkllk
Answer:
x = 4.5
Step-by-step explanation:
First, we can subtract 2 from 20 (20 - 2) to get 18.
Now we know that x has to be multiplied by 4 and have a product of 18.
We can divide 18 by 4 to figure out what x is.
18 ÷ 4 = 4.5
We can check our answer by solving the equation:
4(4.5) + 2 = 20
18 + 2 = 20
20 = 20

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 )

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

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
