Answer:
80
Step-by-step explanation:
Let the number be x
6/7 X 28/1 = 30/100x
x=80 the number is 80
Answer:
The polygon has 3 sides ( a triangle).
Explanation:
The sum of the angles of a polygon can be written as;
where n is the number of sides of the polygon.
Given that the sum of the angles in the polygon is 180 degree;
Therefore, the polygon has 3 sides ( a triangle).
Let x = the number of green apples, let 4x = the number of red apples
4x + x = 50 Set up the quation
5x = 50 Combine like terms
---- ---- Divide by 5 on both sides to get x alone
5 5
x = 10 green apples
4x = 4(10) = 40 red apples
40 - 10 = 30. Suzanne bought 30 more red apples than green apples.

Answer:
- MN = 68°
- LM = 25°
- KLN = 180°
- JLN = 248°
- JN = 112°
- NJL = 267°
Step-by-step explanation:
The relevant relationships are ...
- the sum of arcs around a circle is 360°
- a diameter divides the circle into two 180° arcs
- the whole is the sum of the parts
- the measure of an arc is the measure of the corresponding central angle
__
The arc measures can be found to be ...
MN = 68°
LM = 180° -68° -87° = 25° . . . . semicircle KLN less the marked angles
KLN = 180° . . . . a semicircle
JLN = JM +MN = 180° +68° = 248° . . . . semicircle JLM + MN
JN = 180° -68° = 112° . . . . semicircle JNM less MN
NJL = 180° +87° = 267° . . . . semicircle NJK + KL
