Answer:
d
Step-by-step explanation:
the Selling price of the first pipe = $1.20
Profit = 20%
Let’s try to find the cost price of the first pipe
CP = Selling price - Profit
CP = 1.20 - 20% of CP
CP = 1.20 - 0.20CP
CP + 0.20CP = 1.20
1.20CP = 1.20
CP = 1.201.20
CP = $ 1
the Selling price of the Second pipe = $1.20
Loss = 20%
Let’s try to find the cost price of the second pipe
CP = Selling price + Loss
CP = 1.20 + 20% of CP
CP = 1.20 + 0.20CP
CP - 0.20CP = 1.20
0.80CP = 1.20
CP = 1.200.80
CP = $1.50
Therefore, total cost price of the two pipes = $1.00 + $1.50 = $2.50
And total selling price of the two pipes = $1.20 + $1.20 = $2.40
Loss = $2.50 – $2.40 = $0.10
Therefore, Mr. Jones lost 10 cents.
Answer:
the third obtuse angle is 110°.
Step-by-step explanation:
From the question, the 0s at the back of the given angles are meant to be degrees (°), since the sum of angles in a triangle cannot exceed 180°.
Hence, The question would be:
The two angles of an obtuse triangle are 23° and 47°. Find the third obtuse angle
.
Step-by-step explanation:
In a triangle, there are three (3) angles which sum up to 180°.
Two of the angles are given which are 23° and 47°. Now, to determine the third angle which is an obtuse angle.
(NOTE: An obtuse angle is a type of angle that is greater than 90° but less than 180°).
Let the third obtuse angle be x
Then , we can write that
23° + 47° + x = 180° (Sum of angles in a triangle)
Then,
70° + x = 180°
x = 180° - 70°
x = 110°
Hence, the third obtuse angle is 110°.
Answer:
c
Step-by-step explanation:
hope this helps you out
Coordinates of the center you can find from
x-3=0 and y+5=0
x=3 and y=-5
(3,-5) is the center of the circle.
25 is a square of the radius.
r²=25, so
r=5
Center (3,-5), r=5
So, the answer is D.
