Answer:
Approximately 50.26
Step-by-step explanation:
To find circumference you have to do 2pi x r. We know that the radius of a diameter of 16 is 8, so we'll do 2pi x 8, which is approximately 50.26.
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
Solve the equation for x:
| 4x - 3] = 7
Answer:
x=-1, 5/2.
Step-by-step explanation:
abs(4x-3)=7
4x-3=7, 4x-3=-7
4x=7+3=10
x=10/4=5/2
----------------
4x=-7+3
4x=-4
x=-4/4=-1
Answer:
x = 2.5 or 5/2
Step-by-step explanation:
4x - 3 = 7
+3 +3
4x = 10
divide by 4
x = 2.5, or 5/2

using a straight line. How far is the gas station from Angelica’s house? Show your work.
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

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
triangle = 5x 3 x1/2 = 7.5
7.5 x 2 = 15
total = 103

Answer:
0.867 in decimal form
13/15 in fraction form
Step-by-step explanation:
1. Add
2/3 + 1/5 = 10/15 + 3/15
2. Simplify the sum, 13/15
1 is the greatest common divisor of 13 and 15. The result can't be further reduced.
3. Convert 13/15 into a decimal.

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.

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)
