Find the missing angle of a triangle with 60 degrees and 40 degrees

1 answer:

3 0

The sum of the interior angles of a triangle = 180 degrees. So, all of the angles on the inside of the triangle will add up to 180.

60 + 40 + ? = 180

100 + ? = 180

? = 80

The missing angle in the triangle is 80 degrees.

Hope this helps!

Adriana is planning to ride the public bus to and from school this year. She wants to figure out how much it will cost her. The

lutik1710 [3]

Answer:

C is the dependent variable and r is independent

Step-by-step explanation:

Adriana can ride the bus any number of times she wants. No one is stopping her from doing that so 'r' becomes an independent quantity.

Whereas, the total cost for the bus rides depends on the number of times Adriana rides the bus and the relation is given as, C=1.25r

This is because it costs $1.25 each time she rides the bus in one direction

Arithmetic and geometric series -Find the sum of the first 50 terms of the following series, to the nearest integer.

grandymaker [24]

Answer:

Step-by-step explanation:

21-13=8 and 29-21=8

So this is aritmetic series where a₁ = 13, and r = 8

Sum of the first n terms:

$S_n=\dfrac{a_1+a_n}{2}\cdot n=\dfrac{a_1+a_1+(n-1)r}{2}\cdot n=\dfrac{2a_1+(n-1)r}{2}\cdot n\\\\\\S_{50}=\dfrac{2\cdot13+(50-1)\cdot8}{2}\cdot50=(13+49\cdot4)\cdot 50=10,450$

Domain and range of the inequality y<√x+3 +1

Margaret [11]

The domain of the given inequality is y>1.

<h3>What is Inequality?</h3>

An inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions.

Here, given inequality:

y < $\sqrt{x+3}+1$

Related equation:

y = $\sqrt{x+3}+1$

The equation defined as,

x+3 > 0

x > -3

In the given inequality, the sign of inequality is <, it means the points on the boundary line are not included in the solution set. Thus, -3 is not included in the domain.

So, the domain of the given inequality is x>-3.

We know that,

$\sqrt{x+3} \geq 0$

adding 1 on both sides, we get

$\sqrt{x+3} + 1 \geq 1$

y ≥ 1

The points on the boundary line are not included in the solution set. Thus, 1 is not included in the range.

Thus, the domain of the given inequality is y>1.

vovangra [49]

Answer:

C - 3,600

Step-by-step explanation:

100 16 45 ÷ 2

50. 8. 45 ÷ 2

25. 4. 45 ÷ 2

25. 2. 45. ÷ 2

25. 1. 45. ÷ 3

25. 1. 15. ÷ 3

25. 1. 5. ÷ 5

5. 1. 1. ÷ 5

1. 1. 1

L.C.M = 2 x 2 x 2 x 2 x 3 x 3 x 5 x 5 = 3, 600

I know this may be confusing but if you don't understand, you're welcome to ask.
