Answer:
155 degrees
Step-by-step explanation:
Every 4 angled shape will equal 360
45+130+30+x=360
205+x=360
155=360
Answer:
Step-by-step explanation:
All the angles in a triangle add up to
Every right angle triangle has a right angle in it which is
So to find the remaining angle, you do - - =
The problem says that the expression (3x + 5)(5x − 1) <span>represents the area of the floor of the building in square meters. Therefore, to solve this problem you have to follow the proccedure shown below.
1. First, to simplify the expression (3x + 5)(5x − 1) you must apply the distributive property. Then, you obtain:
15x</span>²-3x+25x-5
2. Then, you have:
15x²+22x-5
3. As you can see, the correct answer is the last option: 15x²+22x-5
Answer:
33 1/3 lb
Step-by-step explanation:
When the distance between them goes from 8 ft to 12 ft, it is 1.5 times what it was. Then the force will be multiplied by the inverse of the square of this:
(75 lb)×1/(1.5²) = 75/2.25 lb = 33 1/3 lb
At 12 feet apart, the attraction force is 33 1/3 pounds.
Answer:
3/8 = 9/24
1/3 = 8/24
3/8 > 1/3
Step-by-step explanation:
3/8 = 9/24 (multiply both numerator and denominator by 3)
1/3 = 8/24 (multiply both numerator and denominator by 8)
9/24 > 8/24
