Daniel created an intersection with his race track. One of the angles at the intersection is 55°. What are the three other angle
melomori [17]

Answer:

55, 125 and 125

Step-by-step explanation:

In this question, we are asked to find the other 3 angles in an intersection.

Please check attachment for what the diagram of the intersection might look like.

The intersection consists simply of 4 angles meeting at a point with the 2 angles on each side vertically opposite to the angles on the other side.

since one of the angles is 55, and we are having a straight line, the other angle would be 180-55 = 125.[ sum of angles on a straight line is 180]

These two angles are vertically opposite, this means that the other three angles are 55,125 and 125.

AnnZ [28]

Answer:

Normally, Acceleration due to gravity is

9.8m/s^2\\

or

10m/s^2

Step-by-step explanation:

From the web

These two laws lead to the most useful form of the formula for calculating acceleration due to gravity: g = G*M/R^2, where g is the acceleration due to gravity, G is the universal gravitational constant, M is mass, and R is distance

Hannah is 2 times her sister’s age. The sum of their ages is no more than 18 years. 1) Write an inequality that can be used to r
svetoff [14.1K]

Answer:

1) x+2x\leq 18.

2) 6 years

Step-by-step explanation:

Let Hanna's sister be x years old.


Then Hanna will be 2x years old.


The sum of their ages will be x+2x years.

The statement "no more than 18" means the sum of their ages is less than or equal to 18.

The required inequality is;

x+2x\leq 18.

2)

The inequality we just found is


x+2x\leq18.

We simplify to get;

3x\leq 18.

we divide both sides by 3 to get;

x\leq 6.

Therefore the oldest age Hannah's sister can be is 6 years

What percent of 300 is 90. Help please
Katyanochek1 [597]
30%.

Well, the simplest way to do it is to put it as a fraction.
90/300.

This is the same as 3/10, which is the same as .30, which is the same as 30% :P

Hope this helped!
