0.5 => 5/10 => 1/2
12.3 => 123/10
0.07 => 7/100
0.625 => 625/1000 => 25/40 => 5/8
Answer: (3,-6)
Step-by-step explanation: Find the answer by finding the negative of the other number.
Answer:
I think <em>t </em>is 72, because the angle looks equal to the known degree, which is 72. And since all the degrees have to add up to 180, 72+72 is 144 and 180-144 is 36. So angle <em>s </em>is 36 degrees.
Area of the composite figure = 390 ft²
Solution:
The composite figure is splitted into two rectangles.
The image is attached below.
Length of vertical rectangle = 20 ft
Width of vertical rectangle = 7 ft
Area of vertical rectangle = length × width
= 20 × 7
Area of vertical rectangle = 140 ft²
Length of top rectangle = 25 ft
Width of top rectangle = 30 - 20 = 10 ft
Area of top rectangle = length × width
= 25 × 10
Area of top rectangle = 250 ft²
Area of the composite figure = 140 ft² + 250 ft²
Area of the composite figure = 390 ft²
Answer:
Quarters = 8
Nickles = 6
Step-by-step explanation:
Call their numbers x and y.
The number equation is
x + y = 14
The value equation is
5x + 25y = 230
5x + 25y = 230-(5x + 5y = 70)
20y = 160
y = 8
x= 6
