James and Martha are discussing special right triangles. James believes that a 30-60-90 triangle with a hypotenuse of 10 feet has a greater perimeter than a 45-45-90 triangle with a hypotenuse of 10 feet. Martha disagrees. Who is correct?
Answer:
Step-by-step explanation:
Disclaimer it is up the student to verify all the geometry algabra and mathematical formulas and calculation .
cosФ = opp/hyp sinФ = adj/hyp hyp = 10 perimeter = a + b + c
for the 45° right triangle
a = b so 2a² = hyp² perimeter 45 = a + a + hyp
P45 = 2a + hyp a = sin(45) (hyp) = [1/2√2)] (hyp) sin(45) = (√2)/2
P45 = 2([1/2√2)] (hyp) + hyp
P45 = hyp (√2 + 1)
for the 30° right triangle
a = hyp×sin(30) b = hyp×cos(30) perimeter 30 = a + b + hyp
sin(30) = 1/2 cos(30) = (√3)/2
a = hyp(1/2) b = hyp(1/2)(√3)
P30 = a + b + hyp
= hyp(1/2) + hyp(1/2)(√3) + hyp
= hyp[ 1/2 + (1/2)√3 + 1]
= hyp[ 1/2 + (1/2)√3 + 1] factored out the hyp
= (1/2)hyp[ 1 + √3 + 2] factored out a 1/2
P30 = (1/2)hyp[ 3 + √3]
which is greater P45 or P30? vso I set both perimeters equal to each other
P45 vs P30
hyp (√2 + 1) = (1/2)hyp[ 3 + √3] the hyp cancel
(√2 + 1) = (1/2)[ 3 + √3] still tough to tell needed
1.414 + 1 = (1/2)[ 3 + 1.732] to go to the calsulator
2.414 vs 1/2( 4.732)
2.414 > 2.366 thus P45 > P30 < ----- Final Answer

Answer:
Step-by-step explanation:
For two lines to be perpendicular to each other the product of their slopes must be -1.
First we need the slope of the reference line. Since
y=mx+b, where m is the slope and the line we are given is
y=2x-4
So we know the slope is 2. So our perpendicular will satisfy
m1(m2)=-1
2m=-1
m= -1/2
So now our line is
y=-x/2+b, using point (0,-7)
-7=-0/2+b
-7=b, now we have the complete line
y=-x/2-7
(Or more neatly)
y=(-x-14)/2

Answer:
The bearing of B from C is 22° counterclockwise
Step-by-step explanation:
∠CAB = 210 - 90 = 120°
Extend a line from A to the west.
drop a perpendicular line from that line to point C.
Let's call the point at the perpendicular point, M.
∠MAC = 180° - 120° = 60° because they are supplementary.
Now we have a right ∠CMA with a known hypotenuse and a known angle.
Solve for MA:
cos 60° = MA/3.8 = 1.9
Solve for MC:
sin 60° = MC/3.8 = 3.29
MB = 1.9 + 6.4 = 8.3
tan ABC = 3.29/8.3 = 21.62°

PLZ HELP WILL GIVE BRAINLIST IF CORRECT! If the sales tax rate is 7% in California, then how much would you pay in Los Angeles for a coat that cost $120.00?
Answer:
the answer would be $128.40
Step-by-step explanation:
7% times 120 is 8.4
8.4 plus 120 is 128.4
The amount to be pay for coat is $128.4
Step-by-step explanation:
Given:The sales tax rate is 7.25% in California.
The cost for a coat in Los angeles is $120.00.
Now, to find amount to be paid.
Sales tax = 7.00%.
Cost = $120.00.
So, amount to be paid = $120 + 7.00% of $120.00.
[tex]=120+\frac{7.00}{100} *120\\=120+\frac{84}{10} \\=120+\frac{42}{5} \\=128.4!![/tex]

Give step by step instructions and the final answer on how to find the volume of a right square pyramid who has a slant height of 5 inches and the length of the base is 4 inches.
To earn full points you must :
- Show each step of your work
- Keep it organized and easy to read
- Give a brief explanation of why you perform each step
- give the correct final answer
Answer:
Below.
Step-by-step explanation:
First find the perpendicular height of the pyramid.
The median of one of the faces, the height and and half the length of the square base make a right triangle with base 2 and hypotenuse 5, so using the Pythagoras theorem:
5^2 = 2^2 + h^2
h^2 = 5^2 - 2^2 = 21
h = √21 inches.
The volume of the pyramid V = 1/3 * h * area of the base, so
V = 1/3 * 4^2 * √21
= 24.44 in^3 to nearest hundredth.
The volume of a right square pyramid will be (16√21) / 3 cubic units.
What is the volume of the pyramid?Let h be the height of the pyramid, l be the slant height and A be the base area of the pyramid.
Then the volume of the pyramid will be
Volume = (1/3) × A × h
The slant height is given as.
l² = (half of side)² + h²
A right square pyramid has a slant height of 5 inches and the length of the base is 4 inches.
Then the height of the pyramid will be
5² = (4/2)² + h²
h² = 25 - 4
h = √21 inches
Then the volume of a right square pyramid will be
Volume = (1/3) × 4 × 4 × √21
Volume = (16√21) / 3
Thus, the volume of a right square pyramid will be (16√21) / 3 cubic units.
More about the volume of the pyramid link is given below.

What are functions?Functions is the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
here,
The standard linear equation is given as,
y -y₁ =(y₂ - y₁) / (x₂ - x₁) (x - x₁)
put the values from the data table,
y - 120 = [(215-120)/(2-1)](x - 1)
y = 95(x - 1) + 120
y = 95x - 95 + 120
y = 95x + 25
Thus, the required expression for climbing the rock formations is given as y = 95x + 25.

Circle X has a circumference of 72π.what is the diameter of circle X?
Answer:36 in
Step-by-step explanation:
The formula for circumference is: C = 2πr
π = 3.14
r = radius.
The Circumference given to us is 72π. Plug in 72π for C
72π = 2πr
Isolate the variable, r. Divide 2 and π from both sides
(72π)/2π = (2πr)/2π
r = (72π)/2π
r = 36
36
Answer: 72
Step-by-step explanation:
since the formula of circumference is C= Pi times the diameter, In some cases when they don't say what Pi is same thing here. So, you would put the diameter and the pi sign next to each other. So 72 is the diameter.
What is the domain and range for all cube root functions?
Answer:For the cube root function f(x)=3√x f ( x ) = x 3 , the domain and range include all real numbers. Note that there is no problem taking a cube root, or any odd-integer root, of a negative number, and the resulting output is negative (it is an odd function).
Step-by-step explanation:
The domain and range for all cube root functions is set of all real numbers.
What is domain and range of the function?The domain and range are defined for a relation and they are the sets of all the x-coordinates and all the y-coordinates of ordered pairs respectively. For example, if the relation is, R = {(1, 2), (2, 2), (3, 3), (4, 3)}, then:
Domain = the set of all x-coordinates = {1, 2, 3, 4}
Range = the set of all y-coordinates = {2, 3}
The domain of a cube root function f (x) = ∛x is the set of all real numbers (R) because it can be calculated for all values of x. Its range is also equal to the set of all real numbers because it will result in all real numbers as y-values.
The range of a cube root function is all real numbers except for 0.
Therefore, the domain and range for all cube root functions is set of all real numbers.

HELP!!!
A father is 30 years older than his son. In 12 years the father will be three times as old as his son. Find their present ages.
ASAP PLZ
i am garbage dont listen to the old answer
Answer:
Son is 3. Father is 33.
Step-by-step explanation:
Let the present age of the son be 'x' years.
Then father's age will be (x + 30) years
Given : After 12 years, the father will be three times as old as his son. Therefore,
(x + 12)3 = x + 30 + 12
3x + 36 = x + 42
3x - x = 42 - 36
2x = 6
x = 3
The present age of son is 3 years and the present age of the father is 3 + 30 = 33 years.
