What is the area and perimeter of the equilateral triangle? Round your final answer to the nearest tenth of a square unit.
Answers
Answer:
In general, the height of an equilateral triangle is equal to √3 / 2 times a side of the equilateral triangle. The area of an equilateral triangle is equal to 1/2 * √3s/ 2 * s = √3s2/4. 2 ways to find the area of a triangle using Pythagorean Theorem? 1. Using Pythagorean theorem. The basic formula for triangle area is side a (base) times the height h , divided by 2: area = (a * h) / 2 2.Using trigonometry. Let's start from the trigonometric triangle area formula: area = (1/2) * a * b * sin(γ) , where γ is the angle between sides.

A triangular pyramid has a volume of 48 in3. The base edge is 9 in and the base height is 4 in. Find the height of the pyramid.
Answers
Answer:
8 in
Step-by-step explanation:
First of all we have to find the area of the base triangle.
For do this we can use this formula:
A = (base edge x base height)/2
A = (9 x 4)/2 = 18 in^2
The formula for find the volume of a pyramid is:
V= Base area x height)/3
So the height can be find in this way
3 x V = base area x height
height = (3 x V)/base area
height = (3 x 48)/18 = 8 in

A rectangular tank with length 50 cm and width 30 cm contains 36 litres of water. Find the depth of the water.
Answers
Answer:
24cm
Step-by-step explanation:
Given data
Length=50cm
Width= 30cm
Volume = 36liters
=36000cm^3
We know that the expression for volume is
V= L*W*H
substitute
36000=50*30*H
36000= 1500*H
H= 36000/1500
H= 24cm
Hence the height is 24cm

Indicate the equation of the given line in standard form.
The line that contains the point Q( 1, -2) and is parallel to the line whose equation is
y - 4 = 2/3 (x - 3)
Answers
Answer:
The equation of the line is;
3y = 2x-8
Step-by-step explanation:
Firstly, we need the to get the slope of the given line
To do this, we will write the equation of the line in the standard form
the standard form
is;
y = mx + b
where m is the slope and b is the y-intercept
y -4 = 2/3(x-3)
y -4 = 2x/3 - 2
y = 2x/3 -2 + 4
y = 2x/3 + 2
with respect to the given equation, the slope of the line is 2/3
Mathematically, when two lines are parallel, the slopes of the line are equal
So now, we want to find the equation of the line that has a slope of 2/3 and passes through the point (1,-2)
so;
y = 2x/3 + b
So substitute the values of (1,-2)
1 for x and -2 for y
-2 = 2/3(1) + b
-2 = 2/3 + b
b = -2 - 2/3
b = (-6-2)/3 = -8/3
So the equation of that line is;
y = 2/3x - 8/3
Multiply through by 3
3y = 2x - 8

The equation A= 1750(1.04)t represents an account balance t years after the account was created. Which statement is correct?
A. The account balance will decrease 0.04% each year.
B. The account balance will increase 0.04% each year.
C. The account balance will decrease 4% each year.
D. The account balance will increase 4% each year.
Answers
Answer:
D. The account balance will increase 4% each year.
Step-by-step explanation:
Given the equation :
A= 1750(1.04)t
This is an exponential growth rate equation which has it's general format as :
A = A0 * (1 + r)^t
A0 = initial value,
Since (1 + r) is greater Than 1 ; then we conclude that it is a growth relation.
1 + r = 1.04
The rate, r = (1.04 - 1) = 0.04
r = 0.04 = (0.04 * 100%) = 4%
Hence, The account balance will increase 4% each year.

Answers
Answer:
Each constellation will have 5 little stars.
Step-by-step explanation:
First, let's organize the information we have:
5 big stars25 little starsEach constellation should have 1 big starEach constellation should have the same amount of starsNow, let's solve the problem:
Each constellation should have 1 big star, and Seth has 5 big stars, so we can infer that there would be 5 constellations.Since each constellation have 1 big star, and the amount of stars in each constellation is the same, the amount of little stars in each constellation are the same.We have 25 little stars, and there are 5 constellations; 25 ÷ 5 = 5, so each constellation have 5 little stars.write 19/41 in lowest forms

Answer:
Antonio is the right one
Answer:
∠ A = 123°
Step-by-step explanation:
The central angle A is equal to the arc that subtends it , so
∠ A = arc DE = 5x - 2
The angles subtended by the radii and tangents of a circle are supplementary
2x + 7 + 5x - 2 = 180 ← Antonio is correct
7x + 5 = 180 ( subtract 5 from both sides )
7x = 175 ( divide both sides by 7 )
x = 25
Then
∠ A = 5 - 2 = 5(25) - 2 = 125 - 2 = 123°
Which of the following would not be a line in solving the equation:
7x-8-5x = 52
12x = 60
12x = 44
12x - 8 = 52
x = 5
Answers
Answer:
Step-by-step explanation:
Let's actually solve the equation. By doing so we should readily see which of the given equatins are not part of the solution.
7x - 8 - 5x = 52 becomes 2x - 8 = 52 if we consolidate the x terms. Next, we consolidate the constant terms on the right, obtaining 2x = 60.
Then x = 30 is the solution.
12x = 60 would not be part of the solution.
12x = 44 would not either.
12x - 8 = 52 would not either.
x = 5 would not be part of the solution.
Again: The solution is x = 30.
