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?
Answer:
Step-by-step explanation:
Those standing is the same thing as people who didn't have seats.
Those standing = the total number of people attending - those seated.
Those standing = 5609 - 3800
Those standing = 1809

3w - 10>-4
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
Ayuda es un examen determinado raíz cuadrada entera de cada número y el residuo en cada caso º60 º86 º96 Raíz:_residuo:_ raíz:__residuo__ raíz__residuo
Answer:
Los pasos para calcular la raíz cuadrada entera y su residuo o resta se dará en la explicación;
Step-by-step explanation:
-60: Para saber exactamente cuál es su raíz cuadrada entera debemos buscar entre que cuadrados perfectos se encuentra comprendida este valor;
Tenemos que 7x7=49 y 8x8 = 64 (60 está comprendido entre 7 y 8) ,pero como la raíz de 49 se aproxima más a 60 entonces la raíz de 60 es 7 y su residuo o resta será el valor que falta para llegar a 60; así que tenemos:
[tex]\sqrt{60}[/tex]=7 ; residuo: 60-49 =11
-86: 9x9 =81 ;81 se aproxima más a 86 ,entonces la raíz cuadrada entera de 86 es 9 y su residuo es 5:
[tex]\sqrt{86}[/tex]=9; residuo : 86-81= 5
-96: 9x9=81 ; 81 por tanteo se aproxima más a 91,entonces la raíz cuadrada entera de 96 es 9 y su residuo es 15.
[tex]\sqrt{96[/tex]= 9x9 =81 ; residuo : 96-81= 15.

Evaluate each function.
g(x) = 3x + 4; Find g(-4)
A) 10
B) -2
C) -17
D) -8
Answer:
-8
Step-by-step explanation:
so g(x) = 3x+4
to find g( -4) , it simply mean that to replace the x in the function g by the value given which is -4
so when u replaced it give you
g(-4) = 3(-4) +4
= -12 +4
= -8

<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

One method that meteorologists could use to find the height of a layer of clouds about the ground is to shine a bright spotlight directly up onto the cloud layer and measure the angle of elevation from a known distance away. Find the height of the cloud layer in the diagram to the nearest tenth
Answer:
367.6 mStep-by-step explanation:
Use trigonometry
Let the height of the cloud be x, then we have:
tan 35° = x/525x = 525 tan 35°x = 367.6 (rounded)The height of the cloud layer is 367.6 m

Identify the vertex of the parabola and tell whether it is a minimum or a maximum.
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.
In ΔSTU, the measure of ∠U=90°, TS = 65, UT = 56, and SU = 33. What ratio represents the cosine of ∠S?
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
Given the equation y= -3x + 2.5 . When y is 8.5 , what value of x makes the equation true?
Answer:
x = -2
Step-by-step explanation:
y = -3x + 2.5
if y = 8.5 then:
8.5 = -3x + 2.5
-3x = 6
x = -2
What is the difference in area between a circle with a diameter of 3 meters and a square with a side length of 3 meters? Use 3.14 for pie.
pls help me
Answer:
The area of a circle with a diameter of 3 meters:
A = πr² = π(d/2)² = 3.14(3/2)² = 7.065 m²The area of a square with a side length of 3 meters:
A = a² = 3² = 9 m²The difference:
9 - 7.065 = 1.935 m²The square has greater area by 1.935 m²
Answer:
the difference in area between a circle with a diameter of 3 meters and a square with a side length of 3 meters=d²-π/4d²
=3²-3.14/4×3²=1.935m²

can someone explain the answer ?
Answer:
x = 9.5
Step-by-step explanation:
Since you are given the adjacent side and need to find the hypotenuse then you need to use cos = adj/hyp so cos (47) = 6.5/x
So x = 6.5/.682, since cos 47 = .6819983601
x = 9.5
write an equivalent expression for each of the following by combining like terms
3a+4(5a - 4)=
5b -2(5a -b) + 10a
Answer:
17a - 16
7b
Step-by-step explanation:
Given the following expressions
3a+4(5a - 4)=
Expand
3a + 4(5a)- 4(4)
= 3a + 20a - 16
= 17a - 16
For the expression
5b -2(5a -b) + 10a
Expand
5b - 2(5a)-2(-b) + 10a
5b - 10a + 2b + 10a
= 5b + 2b -10a + 10a
= 7b + 0
= 7b
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.
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]
