A triangle has sides with lengths of 5 m, 4 m, and 3 m . Is it a right triangle?
Answer:
Yes.
Step-by-step explanation:
A triangle is a right triangle if the sides satisfy the Pythagorean Theorem, or:
a² + b² = c².
So input the values.
a² + b² = c²
3² + 4² = 5²
9 + 16 = 25
25 = 25
The triangle with sides 3 m, 4 m, and 5 m is a right triangle.
Answer:
Yes, it's a right triangle.
Step-by-step explanation:
We can use the Pythagorean theorem to help.
The theorem states that if a triangle is right, [tex]a^{2} + b^{2} = c^{2}[/tex].
C is the longest side of the right triangle or the hypotenuse.
A and b are the other 2 sides
5 is the greatest so that must be [tex]c[/tex].
4 and 3 are [tex]a[/tex] and [tex]b[/tex]. (It doesn't matter which is a and which is b)
Plug in the numbers:
[tex]4^2 + 3^2 = 5^2[/tex]
Solve:
16 + 9 = 25
25 = 25
This triangle is a right triangle!
Vincent gathered groups of 1 to 8 people and gave every group the same puzzle to solve. He recorded the number of minutes it took each group to solve the puzzle and plotted the results.
Answer:
Larger groups tends to take less time to solve the puzzle.
Step-by-step explanation:
It is given that Vincent gathered few groups from 1 to 8 people and he gave them the same puzzle to solve for each group. The graph is provided which show the relationship between the number of groups and the time taken by each group to solve the puzzle.
From the graph, it cam be seen that, the larger groups is more likely to take less amount of time to solve the puzzle as compared to the smaller groups.

Question #5
Charles cut a slice from a circular pizza with the diameter shown below.
Pizza
15 inches
The slice has an arc length of 21.5 inches along the crust. What is the approximate measure of the
central angle of the slice of pizza Charles cut?
A) 82
B) 164
C) 196
D) 278°
Answer:
Step-by-step explanation:
The approximate measurements of the central angle of the slice of pizza Charles cut will be 164 degrees. The correct option is B.
What is the Length of an Arc?The arc length of a circle can be calculated with the radius and central angle using the arc length formula.
Arc length = ∅/360 × 2πr
Given that pizza is 15 inches the slice has an arc length of 21.5 inches along the crust.
Use the formula above to calculate the value:-
Arc length = ∅/360 × 2πr
21.5 = ∅/360 × 2π ( 7.5 )
∅ = ( 21.5 x 360 ) / 2π ( 7.5 )
∅ = 164 degrees
Therefore, the approximate measurements of the central angle of the slice of pizza Charles cut will be 164 degrees. The correct option is B.

¿A cuanto asciende el valor de un capital de 20.000.000 que se invierte hoy,el cuak se espera recuperar dentro de 2 años,con interes del 12% anual?
Answer:
VF= $25.088.000
Step-by-step explanation:
Dada la siguiente información:
Inversión inicial (VP)= $20.000.000
Tasa de interes (i)= 12% anual
Número de periodos (n)= 2 años
Para calcular el falor futuro (VF) de la inversión, debemos usar la siguiente formula:
VF= VP*(1 + i)^n
VF= 20.000.000*(1,12^2)
VF= $25.088.000

Describe a sequence of transformations that shows that triangle ABC is similar to triangle YZX.
My son needs help on this ASAP. Greatly appreciated.
Answer:
x = 20 degrees
y = 128 degrees
Step-by-step explanation:
First, lets solve for x:
3x-8 = 2x + 12
x = 20 degrees
Let's check our work:
60 - 8 = 40 + 12
52 = 52
Now, lets solve for y:
360 - 104 = 256
Why 360? Because 360 degrees = full circle
256/2 = 128 degrees
y = 128 degrees
Why divided by 2? Because there are 2 parts that are equal (y)
Hope this helps! Sorry for the late answer!

The length of a rectangle is increased by 10% while its breadth is decreased by 10%.
Determine, if any, the percentage change in its area.
Answer:
the new area is 1% smaller.
Step-by-step explanation:
the area of a rectangle is length times breadth.
let's call them a and b
Area = a × b
now, a is increased by 10%. that means it is multiplied by 11/10.
because 100% means the whole thing, 1% means a 1/100th part of the whole. and 10% then means 10 times the 1/100th part of 10 × 1/100 = 10/100 = 1/10
if then simmering increases by 10% it means that it is the original 100% plus 10%.
so, it is 100/100 + 10/100 = 10/10 + 1/10 = 11/10
therefore the new length is
a(new) = a(old)×11/10
in exactly the same way, when the breadth is reduced by 10% we get then
breadth(new) = breadth(old)×9/10
so, Area(new) = a(new)×b(new) = a(old)×11/10 × b(old)×9/10
remember, Area(old) = a(old)×b(old)
so, Area(new) = a(old)×b(old) × 11/10 × 9/10 =
= Area(old) × 11/10 × 9/10 =
= Area(old) × 99/100
that means the new area has lost compared to the old area 1/100th of its size. 1/100th = 1%

area = 16, 4 * 4
Then the top left quart
making a 2 by 4 triangle followed with 4 additional square
making 2 * 4 * 1/2 = 4 + 4 meaning area = 8
then the bottom quart
Making a large triangle of 7 by 3
meaning 7 * 3 * 1/2 = 10.5
total area = 16 + 8 + 10.5 = 34.5

11. The student council is comparing prices for their semi-formal dance. They compare banquet. Hall A charges $40 per person. Hall B charges $20 per person plus $500 fixed fee. Write an equation to represent the relationship between the total cost and the number of people, if the variables are defined as follows:
Answer:
TC (A) = 40x , TC (B) = 500 + 20x
Step-by-step explanation:
Let the number of students be = x
Hall A Total Cost
Relationship Equation, where TC (A) = f (students) = f (x) 40 per person (student) = 40x
Hall B Total Cost
Relationship Equation, where TC (B) = f (students) = f (x) 500 fix fee & 20 per person (student) = 500 + 20x
