What is the measure of all exterior angles of a pentagon
Answer:
72 degrees for each exterior angle and 360 degrees for all of them summed.
Step-by-step explanation:
An exterior angle of a polygon is the angle between the line extending one of its sides and the next side. As you go around a regular n sided polygon doing this, you will rotate through a complete circle of 360 degrees. All these angles are equal, so each one is 360/n.
For the pentagon, n=5, so the sum of all its exterior angles is 360 degrees and each exterior angle is 360/5=72 degrees.
What is the slope of the function y = -3/4x + 5

John lays tile for a living. While trying to create the perfect design for his client, he then drew this pattern containing two right angles and an isosceles triangle.
For the triangles to fit together perfectly, John must determine the measure of angles 1, 2, and 3.
Answer:
Angle 1= 58
Angle 2= 64
Angle 3= 58
Step-by-step explanation:
The two smaller triangles are each right triangles and every triangle equals 180 so add 32 degrees and 90 degrees ( 90+32=122) and subtract that from 180 and you get angles 1 and 3 from your isosceles triangle
then you add both angles 1 and 3 from your isosceles triangle which are 58 degrees each (58+58=116) and subtract that from 180 (180-116=64) and you get angle 2
Answer:
angle 1 = 32
angle 2 = 116
angle 3 = 32

Cual es el valor de un esfero cuando la docena se compra en $7848? Area de un triangulo de 9 unidades de base y 6 unidades de altura? Cien veces la suma de 4.5 con 2.71 Porfavooor es para una tarea de mañana D:
Answer:
a) $654
b) 27 unidades cuadradas
c) 721
Step-by-step explanation:
a) ¿Cuál es el valor de un bolígrafo cuando la docena se compra por $ 7848?
Una docena = 12
Por eso:
12 bolígrafos = $ 7848
1 bolígrafo = $ x
Cruz multiplicar
12 bolígrafos × $ x = 1 bolígrafo × $ 7848
$ x = 1 bolígrafo × $ 7848/12
$ x = $654
b) Área de un triángulo ¿9 unidades de base y 6 unidades de altura?
Área de un triángulo =
= 1/2 × Base × Altura
1/2 × 9 × 6
= 27 unidades cuadradas
c) Cien veces la suma de 4.5 con 2.71
Esto se calcula como:
100 × (4,5 + 2,71)
= 100 × (7.21)
= 721

Answer:
im guessing 11 miles but im not sure
Step-by-step explanation:
Answer:
Answer:
Distance between Gas Station and House = 7.81 miles.
Step-by-step explanation:
Given: House location ( 4, 3 ) and Gas station location ( 10, 8)
On graph 1 unit = 1 mile.
To find: Distance between Gas Station and House
We use the Distance formula to find the distance between two points
From given points and formula,
=
=
= units
Since, 1 unit = 1 mile
⇒
Therefore, Distance between Gas Station and House = 7.81 miles

if y varies directly as the square root of x and y=3, x=3. calculate y when x=64
Answer:
y = 64√3
Step-by-step explanation:
Step(i):-
Given that the 'y' varies directly as √x
⇒ y∝ √x
⇒ y = k√x
Put y=3 and x=3
3 = k ×√3
√3 k = √3×√3
After cancellation '√3' on both sides, we get
k = √3
Step(ii):-
Given that x=64 and k = √3
We have a function y = k√x ..(i)
substitute x =64 and k = √3 in equation (i)
y = √3 × 64
y = 64√3

Answer:
103 ft^2
Step-by-step explanation:
Long sides: 2(8*4) = 64 ft^2
Under side: 3*8 = 24 ft^2
Triangles: (2(3*5))/2 = 15 ft^2
64+24+15 = 103
Answer:
103
Step-by-step explanation:
the base = 3x8 = 24
the sides are= 4 x 8 = 32
two sides = 64

The line of best fit for a data set is y=1.1x+3.4. Find the residual for each of the coordinate pairs, (x,y).
D. (1.5,5.05)
Answer:
Kindly check explanation
Step-by-step explanation:
Given the model:
y=1.1x+3.4
Find the residual:
Residual = Yactual - y
A. (5, 8.8) ; Yactual = 8.8
Residual = 8.8 - (1.1(5) + 3.4) = - 0.1
B.) (2.5,9.95) Yactual = 9.95
Residual = 9.95 - (1.1(2.5) + 3.4) = 3.8
C.) (0, 3.72) Yactual = 3.72
Residual = 3.72 - (1.1(0) + 3.4) = 0.32
D.) (1.5,5.05) Yactual =
Residual = 5.05 - (1.1(1.5) + 3.4) = 0
