Answer:
radius = 7.5 cm
Step-by-step explanation:
Since M is the midpoint of the chord AB then OM is perpendicular to AB
Using Pythagoras' identity in right triangle OMB with hypotenuse OB, the radius of the circle, then
OB² = OM² + MB² = 4.5² + 6² = 20.25 + 36 = 56.25 ( take square root of both sides )
OB = radius = [tex]\sqrt{56.25}[/tex] = 7.5

Answers
Answer:
72°
Step-by-step explanation:
The full plate has a central angle of 360°.
7/35 × 360° = 72°
Answer:
72°
Step-by-step explanation:
In order to find the value of the central angle, you must first determine what percentage of the plate was broken.
Since 7 out of the total 35 inches of circumference were broken, you divide 7 by 35 ([tex]7/35[/tex]) and get 0.2, which means 20% of the plate is broken.
Now, knowing that a circle consists of 360°, you need to find 20% of 360.
Use the formula [tex]\frac{percent}{100} =\frac{part}{whole}[/tex] .
[tex]\frac{20}{100}=\frac{x}{360}[/tex]
360 x 20 = 7200
7200 ÷ 100 = 72
x = 72
So, the central angle is 72°.

6 is 25% of what number? (also I can confirm that this is not a test)
Answers
Answer:
24
Step-by-step explanation:
6/ x = 25%/100%
100*6 = 600
600/25 = 24
Answer:
[tex]6/24 = 25/100\\[/tex]
25% = 1/4 = 6/x
so 4*6 = 24
6 is 25% of 24.

Help pleaseee! This is for my geometry class!
Answers
Answer:
x = 98
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 6 , then
sum = 180° × 4 = 720°
Sum the interior angles and equate to 720
x + 50 + 140 + 112 + x + x + 4 + 120 = 720, that is
3x + 426 = 720 ( subtract 426 from both sides )
3x = 294 ( divide both sides by 3 )
x = 98

A certain high school has 1,488 students. If you subtract the number of girls from boys you get 78. Let x be the number of boys and y be the number of girls.
Answers
Answer:
boys = 705
girls = 783
Step-by-step explanation:
We are to find the number of boys and girls in the school
the answer can be determined using simultaneous equation
x = boys
y = girls
y - x = 78 equation 1
y + x = 1488 equation 2
subtract equation 1 from 2
2x = 1410
x = 1410/2 = 705
Substitute for x in equation 1
y - 705 = 78
y = 705 + 78 = 783

Juan compro un plasma en cuotas que costó $8000 si le faltan pagar 3 cuotas y ya pagó $6500 ¿cual es el valor de cada cuotas fijas?
Answers
Answer:
El valor de cada cuota fija es de $500.
Step-by-step explanation:
Para encontrar el valor de cada cuota fija, puedes calcular la diferencia entre lo que Juan ha pagado y el valor que costó el plasma para saber cuál es el monto que aún debe. Después, debes dividir la cantidad que aún debe pagar entre tres que es el número de cuota pendientes para encontrar el valor de cada cuota teniendo en cuenta que son fijas:
8000-6500=1500
1500/3=500
De acuerdo a esto, la respuesta es que el valor de cada cuota fija es de $500.

Which equation matches the function shown in the graph?
A. y=2sin(1/2x)+1
B. y=3sin(2x)
C. y=2sin(2x)+1
D. y=3sin(1/2x)
Answers
Answer:
the answer is A. y=2sin(1/2x)+1
Step-by-step explanation:
I input all four functions on desmos (a graphing calculator), and saw that A. y=2sin(1/2x)+1 was similar to the function shown in the graph
The function that matches the graph is y= 2 sin(1/2x) +1.
What is graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
Given:
let y = A sin ([tex]\omega[/tex]x + Ф)+ k
T= 4π, w= 2π/T = 1/2
Now, midline= 1/2( max + min)
=1/2(3-1)= 2/2
k=1
and, A= 3-1 = 2
So, y= 2 sin(1/2x + Ф) +1
as, Ф=0
So, y= 2 sin(1/2x) +1
