Answer:
240
Step-by-step explanation:
Gain=25%
Gain=selling price - cost price
Gain = ((selling price - cost price )× 100)/ cost price
25c=(4800-c)100
25c=480000-100c
125c=480000
cost price = 3840
second statement
The selling price was 4080
Cost price 3840
therefore
Gain=selling price - cost price
Gain = 4080-3840
=240
Answer:
278.88 cm
Step-by-step explanation:
Since XY is the perpendicular bisector of JK, and when we say perpendicular, it is a line which cuts a line segment into two equal parts at 90°. So the statements that must be true about it would be all of the above: XY and JK form four right angles, P is the midpoint of XY, m D. XP=YP, JP=KP and XY perpendicular to JK. Hope this answer helps.
-5/3
Step-by-step explanation:
m1 = 3/5
m1 * m2 = - 1. For a pair of perpendicular line.
Usking that m2 = - 5/3
Answer:
c
Step-by-step explanation:
1. We can asume that a = 2, b = 4. Then solve and find which option matches with the answer.
2. Equation itself plugged in with a = 2, and b = 4. 2^2 + 2 x 2 x 4 + 4^2 = 36 / (2 + 4)^3
3. 36 / 216 = 1/6
Find any option that matches your answer and plug in a for 2 and b for 4.
a. a + b = 2 + 4 = 6 - No doesn’t match 1/6
b. a^2 + b^2 = 2^2 + 4^2 = 4 + 16 = 20 - No doesn’t match 1/6
c. 1 / a + b = 1 / 2 + 4 = 1/6 - Yes does match 1/6
d. 1 / (a + b)^2 = 1 / (2 + 4)^2 = 1/36 - No doesn’t match 1/6
