This is the formula for the pythagorean theorem i.e, one leg of a triangle squared plus another leg of a triangle squared equals the hypotenuse squared.
Answer:
[tex]a^2+b^2=c^2[/tex] is the formula for the Pythagorean Theorem
Step-by-step explanation:.
The Pythagorean Theorem, also referred to as the ‘Pythagoras theorem,’ is arguably the most famous formula in mathematics that defines the relationships between the sides of a right triangle. This mathematical law states that the sum of squares of the lengths of the two short sides of the right triangle is equal to the square of the length of the hypotenuse.
A trapezoid has of parallel sides
Answer:
True
Step-by-step explanation:
False. A trapezoid has one pair of parallel sides, not two pairs.
A trapezoid has only one pair of parallel sides.
The definition of a trapezoid states that it is a quadrilateral with exactly one pair of parallel sides.
The non-parallel sides of a trapezoid are called legs, and the parallel sides are referred to as the bases.
So, a trapezoid can have two pairs of sides that are parallel to each other, but only one of those pairs is considered as the bases.

A cell phone company charges a monthly rate of $10.00 and $0.20 a minute per call. Write an equation that can be used to determine the number of minutes, m, of calls made if the bill for one month is $30.
Answer:
y = 0.20m + 10, 100 minutes
Step-by-step explanation:
Equation: y = mx + b
Fill it in.
m = slope = 0.20
b = y-intercept = 10
y = 0.20x + 10 (They wanted the variable to be m. So, changing that.)
y = 0.20m + 10
Fill in.
30 = 0.20m + 10
Solve.
20 = 0.20m
100 = m
She was on the phone for 100 minutes.
Juan mesura 1,75m y proyecta , en un momento dado , una sombra de 1,4m . Calcula la sombra que proyecta en este instante una farola de 4m de altura
Answer:
5m
Step-by-step explanation:
Calculamos usando la fórmula de la proporción
Sombra / Altura
Deje que la altura de la luz de la calle = x
1,4 m / 1,75 m = 4 m / x
Multiplicar cruzada
1,4 × x = 1,75 × 4
Dividir ambos lados por 1.4
x = 1,75 × 4 / 1,4
x = 5
Por lo tanto, la altura de la farola es de 5 m.

A cone has radius 3 and height 4. Your classmate calculates its surface area as shown:
Explain your classmate's error.
S. A. = pi(5)^2 + pi(3)^2 = 25pi + 9pi = 3pi
Answer:
Lateral surface area of cone = π(3)(5)
Lateral surface area of cone = 47.1 unit² (Approx.)
Step-by-step explanation:
Given:
Radius of cone = 3 unit
Height of cone = 4 unit
Find:
Lateral surface area of cone
Computation:
Slant height of cone = √Radius² + Height²
Slant height of cone = √3² + 4²
Slant height of cone = √9 + 16
Slant height of cone = √25
Slant height of cone = 5 unit
Lateral surface area of cone = πrl
Lateral surface area of cone = π(3)(5)
Lateral surface area of cone = (3.14)(15)
Lateral surface area of cone = 47.1 unit² (Approx.)

Joseph's workshop is 12 feet by 7 feet. If the drawing of the workshop has a scale of 1inch = 2 feet, what are the dimensions of the drawing? (enter your answer with a comma separating the two numbers)
Answer:
6, 3.5.
Step-by-step explanation:
Start with the 12 foot measurement. 1 inch of the drawing represents 2 feet, so divide 12 feet by 2 to find out how many inches represent 12 feet. 12/2 is 6. Do the same with the 7 foot measurement. 7/2 is 3.5, so the drawing of the 7 foot side will be 3.5 inches.

Two studies were completed in Georgia. One study in northern Georgia involved 3,000 patients; 84% of them experienced flulike symptoms during the month of December. The other study, in southern Georgia, involved 2,000 patients; 75% of them experienced flulike symptoms during the same month. Which study has the smallest margin of error for a 99% confidence interval?
The northern Georgia study with a margin of error of 2.5%.
The southern Georgia study with a margin of error of 2.5%.
The northern Georgia study with a margin of error of 1.7%.
The southern Georgia study with a margin of error of 1.7%.
Answer:
The northern Georgia study with a margin of error of 1.7%.
All else being equal, the study with the larger sample size has the smaller margin of error. So the result makes sense (as 0.84 is pretty close to 0.75)
Step-by-step explanation:
The best and most correct answer among the choices provided by the question is the third choice "The northern Georgia study with a margin of error of 1.7%."
All else being equal, the study with the larger sample size has the smaller margin of error. So the result makes sense (as 0.84 is pretty close to 0.75)

Help please! Thanks!!!
To get this answer, we'll use the cosine ratio
cos(angle) = adjacent/hypotenuse
cos(A) = AC/AB
cos(35) = b/c
cos(35) = b/280
280*cos(35) = b
b = 280*cos(35)
b = 229.362572400918
b = 229
When you use your calculator, make sure it's in degree mode.

5x-3=19? Answer for Brainliest
Answer:
x = 4.4
Step-by-step explanation:
I'm going to assume you want to solve for x so here we go.
You need to work backwards for this equation, and whatever you do to the LHS, you do to the RHS.
First, you need to remove the minus 3, which means that on both sides, you add 3. Adding three on the LHS makes the -3 disappear, and adding 3 on the RHS makes the 19 go to a 22.
Your equation is now 5x=22.
Since 5x means 5 × x, to get rid of it, you need to divide 5x by 5. Doing it to the LHS will make the five disappear, and doing it to the RHS will make it go to 22 ÷ 5 which equals 4.4
Therefore, x = 4.4
