The average of three consecutive whole numbers is 21, need help asap
Answer: Consecutive numbers: 20, 21, 22
Step-by-step explanation:
Three consecutive whole numbers: x, x+1, x+2
Avg. = [x + (x + 1) + (x + 2)] / 3 = 21
[3x + 3] / 3 = 21
3x + 3 = 63
3x = 60
x = 20
x + 1 = 21, x + 2 = 22
A man 6 feet tall casts a shadow that is 11 feet long. A building casts a shadow of 139 feet long. The building is tall. Round your answer to the nearest 10th
Given:
Height of man = 6 ft
Height of man's shadow = 11 feet
Height of building's shadow = 139 feet
To find:
The height of the building.
Solution:
We know that the heights of the objects and there shadows are always proportional.
[tex]\dfrac{\text{Height of man}}{\text{Height of man's shadow}}=\dfrac{\text{Height of the building}}{\text{Height of building's shadow}}[/tex]
Let x be the height of the building.
[tex]\dfrac{6}{11}=\dfrac{x}{139}[/tex]
Multiply both sides by 139.
[tex]\dfrac{6}{11}\times 139=x[/tex]
[tex]\dfrac{834}{11}=x[/tex]
[tex]75.8181...=x[/tex]
[tex]x\approx 75.8[/tex]
Therefore, the building is 75.8 feet long.

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

Line a is parallel to line b, m<2 = 4x+44 , And m<6=6x+36. Find the value of x
Answer:
x = 4
Step-by-step explanation:
<2 and <6 are equal because of the corresponding angles thm so:
4x + 44 = 6x + 36
4x - 6x = 36 - 44
-2x = -8
x = 4

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
I need help with my hw
Answer:
x = 13, angle = 37
Step-by-step explanation:
The full angle will be a right angle, so 90 degrees.
You are given 53, on one side, so you just need to find the other bit.
Here, you can do 90 - 53 and get 37, which has to be equal to your unknown angle.
2x + 11 = 37
2x = 26
x = 13
Answer:
x=13
Step-by-step explanation:
we know that the 2 angles add up to a 90° right angle
53+ (2x+11) = 90
solving that, we're left with 2x= 26
26÷ 2= 13=x

Answer:
X > -3, 0.28, 4
Step-by-step explanation:
x - 7 > -12 - To solve add 7 to both sides
x > -5 Which means every number GREATER but not EQUAL to 5 will count as a solution to the equation, therefore 5 is not a correct answer. -3 is greater then -5, and any positive number is greater then any negative number.
Therefore the Correct Answer is : -3. 0.28, 4
The graph of h(x) = x² was transformed to create the graph of k(x) = -1/7x²? Which of these describes the transformation from the graph of h to the graph of k?
A.) A reflection over the x-axls and a vertical stretch
B.) A reflection over the x-axis and a vertical compression
C.) A reflection over the y-axis and a vertical compression
D.) A reflection over the y-axis and a vertical stretch
Given:
The functions are:
[tex]h(x)=x^2[/tex]
[tex]k(x)=-\dfrac{1}{7}x^2[/tex]
To find:
The transformation from the graph of h to the graph of k.
Solution:
The transformation is defined as
[tex]k(x)=ah(x+a)=[/tex] .... (1)
Where, a is stretch factor
If 0<|a|<1, then the graph compressed vertically by factor |a| and if |a|>1, then the graph stretch vertically by factor |a|.
If [tex]a<0[/tex], then the graph of h(x) reflected across the x-axis.
We have,
[tex]h(x)=x^2[/tex]
[tex]k(x)=-\dfrac{1}{7}x^2[/tex]
It can be written as
[tex]k(x)=-\dfrac{1}{7}h(x)[/tex] ...(2)
On comparing (1) and (2), we get
[tex]a=-\dfrac{1}{7}<0[/tex]
The graph of h(x) reflected across the x-axis.
[tex]|a|=\dfrac{1}{7}<1[/tex]
So, the graph is compressed vertically.
It means the graph of h reflection over the x-axls and a vertical stretch to get the graph of k.
Therefore, the correct option is B.

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
does anyone know how to complete this problem? i need to find x. any help will be greatly appreciated <3
Step-by-step explanation:
I think you need to do:
44(7x+12)(7x+12) = 180
so
44(49x²+178x+144) = 180
2156x²+7832x+6336= 180
and you finish and you find x

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

<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

Answer:
first image -2.4/3, second image the x intercept is 28, and it represents the time it takes to totally empty the pool
Step-by-step explanation:
the rate of change, or slope, of an equation is the change in y over the change in x. 11-13.4 = -2.4 and 5-2 =3
the x intercept is the x value when y = 0, so 28 in this case. the question is graphing the total volume of a pool and how long it takes to empty it, so when the pool has no water left in it then that's how long it takes to empty

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
