A stadium has seating accommodation for 3800 people. At a cricket match all seats were taken. If there were 5609 people attending the match, how many people didn't have seats?​

Answers

What is the solution to the inequality shown?
2(x + 3) < 6 - x

Answers

Answer:

x = 0

Step-by-step explanation:

Step 1: Simplify both sides of the inequality.

2x+6<−x+6

Step 2: Add x to both sides.

2x+6+x<−x+6+x

3x+6<6

Step 3: Subtract 6 from both sides.

3x+6−6<6−6

3x<0

Step 4: Divide both sides by 3.

3/3 < 0 /3

x = 0

In ΔSTU, the measure of ∠U=90°, TS = 65, UT = 56, and SU = 33. What ratio represents the cosine of ∠S?

Answers

Answer:

33/65

Step-by-step explanation:

Given the following

∠U=90°,

TS = 65 = HYpotenuse

UT = 56 = Opposite

SU = 33 = Adjacent

Cos <S = adj/hyp

Cos <S = SU/TS

Cos <S = 33/65

Hence the required ratio is 33/65

3w - 10>-4

Answers

Answer:

If your trying to find w then it'll be 2

Step-by-step explanation:

3w - 10 > -4

      +10    +10

3w > 6

3       3

w > 2

So I added 10 on both sides and guess positive 10 is bigger than -4, it'll be a positive 6. Then I divide 3 on both sides after I got 6 and thats how I got 2

Identify the vertex of the parabola and tell whether it is a minimum or a maximum.

Answers

Answer:

First parabola's vertex is (-2,2), which is a minimum.

Second parabola's vertex is (3,2), which is a maximum.

Step-by-step explanation:

Simply, a vertex of a quadratic is a graph's turning point.

The maximum and minimum can be identified by seeing if the graph curves up or down.

Maximum occurs when your graph is facing down.

Minimum occurs when your graph is facing up.

Quadrilateral BCDE is inscribed in circle A. The measure of ⏜ is 73°. The measure of ⏜ is 53° and the measure of ⏜ is 102°.


Determine the measure of ∠ BCD.

Answers

Answer:

117

Step-by-step explanation:

Angle BCD intercepted arc is Arc DEB.

We know DE measure but we need to find EB measure.

Since a circle circumference add up to 360, we can add all of the known arcs up to 360 to find the missing arc.

[tex]73 + 53 + 102 + x = 360[/tex]

[tex]126 + 102 + x = 360[/tex]

[tex]228 + x = 360[/tex]

[tex]x = 132[/tex]

So arc EB measure 132.

Arc eb and de.

132+102=234.

Angle BCD is inscribed angle of Arc DEB, so that means angle BCD is half of Arc DEB.

[tex] \frac{234}{2} = 117[/tex]

A. angle measures of 339, 679, and 80°

<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3

Answer:

Let's solve your equation step-by-step.

11x − 2x + 15 = 8 + 7 + 9x

Step 1:

Simplify both sides of the equation.

11x − 2x + 15 = 8 + 7 + 9x

11x + −2x + 15 = 8 + 7 + 9x

( 11x + −2x ) + ( 15 ) = ( 9x ) + ( 8 + 7 )

( Combine Like Terms )

9x + 15 = 9x + 15

9x + 15 = 9x + 15

Step 2:

Subtract 9x from both sides.

9x + 15 − 9x = 9x + 15 − 9x

15 = 15

Step 3:

Subtract 15 from both sides.

15 − 15 = 15 − 15

0 = 0
