True , a scalene does not have any congruent angles.

Answer:

True

Step-by-step explanation:

A scalene triangle has non congruent sides and non congruent angles which means that all the sides and the angles are not congruent to each other.

Now, if two angles are given which are congruent, then the triangle is definately not scalene because scalene triangle do not have congruent angles,

Thus the given statement is true.

How to evaluate higher powers of i

Arisa [49]

Answer:

i^0 = 1

i^1 = i

i^2 = -1

i^3 = -i

i^4 = 1

i^5 = i

i^6 = -1

i^7 = -i

i^8 = 1

i^9 = i

Step-by-step explanation:

Anything raised to 0 is 1

Anything raised to 1 is itself

I just always knew i^2 = -1

I put this rest into the calculator honestly

But if you look at the stuff from i^2, you'll notice there's a pattern (-1, -i, 1, i) and it repeats. I bet if you raise i to the 10th, 11th, 12th, and 13th power, it is going to repeat the same pattern. I hope this helps in any way.

A telephone pole 10 meters tall casts a shadow 8 meters long at the same time that a tree nearby cast a shadow 14 meters long. H

Agata [3.3K]

ok so i think it is 16 meters longs because 10 - 8 = 2 which means the actual thing was bigger than its shadow so 14 +2 = 16 and to double check if it was right 16 - 14 = 2

Two kinds of tickets to an outdoor concert were sold: lawn tickets and seat tickets. fewer than 400 tickets in total were sold.

Natali [406]

Answer:

Part a) $x+y < 400$

Part b) The graph in the attached figure

Part c) see the explanation

Part d) The number of seat tickets sold must be less than 300 tickets

Step-by-step explanation:

Part a) write an inequality to describe the constraints. specify what each variable represents

Let

x ----> number of lawn tickets sold

y ----> number of seat tickets sold

we know that

The sum of the number of lawn tickets sold plus the number of seat tickets sold must be less than 400 tickets

The linear inequality that represent this situation is

$x+y < 400$

Part b) use graphing technology to graph the inequality. sketch the region on the coordinate plane

we have

$x+y < 400$

using a graphing tool

The solution is the triangular shaded area of positive integers (whole numbers) of x and y

see the attached figure

Remember that the values of x and y cannot be a negative number

Part c) name one solution to the inequality and explain what it represents in that situation

we know that

If a ordered pair lie on the solution of the inequality, then the ordered pair is a solution of the inequality (the ordered pair must satisfy the inequality)

I take the point (200,100)

The point (200,100) lie on the triangular shaded area of the solution

<u><em>Verify</em></u>

Substitute the value of x and the value of y in the inequality and compare the result

For x=200,y=100

$x+y < 400$

$200+100 < 400$
