Answer:66.67%

Step-by-step explanation:What percent of the games did the team win? Question 1114417: A baseball team has won 20 games and lost 10 games. What percent of the games did the team win? = 66.67%.

Answer:

Move all terms to the left side and set equal to zero. Then set each factor equal to zero.

x=5,−2

Step-by-step explanation:

I can do math

Step-by-step explanation:

Since angles opposite congruent sides in a triangle are congruent, w=67.

Now, since the sum of the measures of the interior angles of a triangle is 180 degrees, x=180-67-67=46

Answer:

81%

Step-by-step explanation:

First, let's set up 3 equations:

w*0.6 = x

x*1.5=y

y*0.9=z

Now, we can substitute x in the second equation for w*0.6:

w*0.6*1.5 = y

Lastly, we can substitute y in the last equation for w*0.6*1.5:

w*0.6*1.5*0.9=z

w*0.81=z

Therefore, z is 81 percent of w.

Answer:

Deducir ecuación de área del cuadrado/Despejar y calcular longitud de lado/Deducir ecuación de perímetro/Calcular perímetro del cuadrado.

Perímetro: 44 pies cuadrados.

Step-by-step explanation:

Podemos explicarle al papa de Rafael lo siguiente:

Estimado señor.

Una piscina de forma cuadrada tiene la forma de un cuadrilátero con cuatro lados iguales y cuatro ángulos rectos en sus vértices. El área del cuadrado es igual a la longitud de cualquiera de sus lados multiplicada por si misma. Es decir:

[tex]A = l\cdot l = l^{2}[/tex] (Eq. 1)

Entonces, la longitud de cualquiera de sus lados es la raíz cuadrada del área de su piscina. Es decir:

[tex]l =\sqrt{A}[/tex] (Eq. 1b)

Donde [tex]l[/tex] y [tex]A[/tex] son la longitud de lado y el área de la piscina, medidos en pies y pies cuadrados, respectivamente.

Si sabemos que su piscina tiene un área de 121 pies cuadrados ([tex]A = 121\,ft^{2}[/tex]), entonces la longitud del lado de piscina es:

[tex]l = \sqrt{121\,ft^{2}}[/tex]

[tex]l = 11\,ft[/tex]

Tenemos que la longitud del lado es 11 pies.

Ahora, el perímetro es la suma de las longitudes de los lados del cuadrado. Si el cuadrado tiene 4 lados de igual medida, entonces el perímetro del cuadrado es igual a cuatro veces esa longitud. Esto es:

[tex]p = 4\cdot l[/tex] (Eq. 2)

Donde [tex]p[/tex] es el perímetro, medido en pies.

Si conocemos que la longitud del lado es 11 pies ([tex]l = 11\,ft[/tex]). En consecuencia, encontramos que el perímetro de su piscina es:

[tex]p = 4\cdot (11\,ft)[/tex]

[tex]p = 44\,ft[/tex]

El perímetro de su piscina es de 44 pies.

The equation of the translated function will be given by f(x) = ( x + 1 ) 2 + 5

The vertex of the original function is (0, 0 )

The vertex of the translated function is (- 1, 5 )

Given f(x) then f(x + a) represents a horizontal translation of f(x)

• If a > 0 then a shift to the left of a units

• If a < 0 then a shift to the right of a units

The translated graph has been shifted 1 unit left, thus

f(x) = (x + 1)²

Given f(x) then f(x) + c represents a vertical translation of f(x)

• If c > 0 then a shift up of c units

• If c < 0 then a shift down of c units

The translated graph has been shifted 5 units up,

Thus the equation of the translated function will be given by f(x) = ( x + 1 ) 2 + 5

Answer:

40 grams of 40% sugar syrup

Step-by-step explanation:

20% of 30 grams = 6grams of sugar

6 grams + 10 grams = 16 grams of 40% instead of 30 now

Therefore, 40g----------100%

                  16g-----------40%

Answer:

   40 grams of 40% sugar syrup

Step-by-step explanation:

40 grams of 40% sugar syrup

30+10== 40 g  

20% sugar in 30  =  1/5 of the syrup is sugar. = 6 g of sugar

6+10 =  16g of sugar in 40 grams of syrup.

16/40=x/100

Answer:

x=3y-2

x+3y=6

if x value is above

place the value of x

3y-2+3y=6

3y+3y_=6+2=8

6y=8

y=8/6=4/3

y=4/3.

Answer:

Step-by-step explanation:

if Points X and Z are on a number line and point Y partition line XZ into two parts where XY: YZ = 1:4, this can be expressed as;

XY/YZ = 1/4

cross multiply;

YZ = 4XY

Also, if The coordinate of X is 1.3, and the coordinate of Y is 3.8, then the distance XY will be expressed as XY = 3.8 - 1.3

XY = 2.5

YZ = 4(2.5)

YZ = 10

Since Y is at 3.8 and YZ is 10, then coordinate Z will be YZ + Y

coordinate of Z = 10+3.8

coordinate of Z = 13.8

Answer: (3)

Step-by-step explanation:

The function that shows this situation is given by Q(t) = 3.5t + 55

A linear equation is in the form:

y = mx + b

Where y, x are variables, m is the rate of change and b is the y intercept.

Let Q(t) represent the total number of boxes, and t is the time since noon in hours.

A warehouse contains 55 boxes, hence b = 55. At 3:30 pm (3.5 hours), the warehouse contains 90 boxes.

90 = 3.5m + 55

m = 10

The function that shows this situation is given by Q(t) = 3.5t + 55

Step-by-step explanation:

(x1, y1) =A(2,3)

(x2,y2) =B(-1,-1)

Using distance formula,

AB^2 = (x2-x1) ^2 +(y2-y1) ^2

=(-1-2)^2 +(-1-3)^2

=9+16

=25

Therefore, AB=5 units

Answer:

Percentage of light that penetrates at 150 m will be 0.94%.

Step-by-step explanation:

By using logarithmic regression calculator,

Equation of the regression line will be,

y = 104.5173 - 20.6711(lnx)

Where x represents the depth of the ocean

And y will represent the penetration of light

Therefore, at the depth of 150 m, penetration of the light will be,

y = 104.5173 - 20.6711[ln(150)]

  = 104.5173 - 103.5753

  = 0.9420

  ≈ 0.94 %

Therefore, percentage of light that penetrates at 150 m will be 0.94%.
