Answer:

For #9 it can be 4,6, or 7

#10 is angle 3

#11 is 134

#12 is 49

Step-by-step explanation:

#9 just look at the picture given and see which one is opposite from it

#10 look at which one is beside it but that the ’half‘ circles are facing each other

#11 and #12 subtract the angles they give you and see if they are next to each other and if they are that subtract the number they give you by 180-the degrees of a line

Answer:

[0, infinity

Step-by-step explanation:

It's essential to type "sqrt(x)" or "√x," which are vastly different from the linear function y = x + 1.

The domain of the square root function is [0, infinity).

Adding 1 to this merely shifts the entire graph up 1 unit.

So the domain of y = √x + 1 is the same as before:    [0, infinity

Answer:

x = 4

Step-by-step explanation:

Here, given that the two triangles are similar, we want to find the value of x

Mathematically, when two triangles are similar, the ratio of their corresponding sides are equal

Thus, we have it that;

ED/EF = XY/YZ

5/2x-1 = 10/14

14(5) = 10(2x-1)

70 = 20x -10

70 + 10 = 20x

20x = 80

x = 80/20

x = 4

Step-by-step explanation:

cylinder's height=3×(diameter of sphere)=3×6=18 cm

radius of cylinder=3 cm

volume of cylinder=π r²h=π(3)²×18=162 π cm³

volume of sphere=4/3 π(3)³=36 π cm³

reqd. empty space=162 π-3×36π=54 πcm³

Answer:

21 / 252

Step-by-step explanation:

Recall : nCr = n! ÷ (n-r)!r!

The total possible outcome ; 5 questions out of 10

10C5 = 10! ÷ 5!5! = (10*9*8*7*6)÷(5*4*3*2*1) = 252

Required outcome :

All 5 questions set being from the 7 questions covered and 0 from the 3 left uncovered

7C5 * 3C0

7C5 = 7! ÷ 2!5! = (7*6) ÷ (2*1) = 21

3C0 = 3! ÷ 3!0! = 1

Probability = required outcome / Total possible outcomes

P(All 5 questions prepared for appears) :

[7C5 * 3C0] ÷ 10C5

(21 * 1) / 252

= 21 / 252

Answer:

1. Juan necesita 0,0051 hl en total.

2. Juan no tendrá suficiente con una lata de medio litro.

Step-by-step explanation:

1. Para calcular el volumen total en hl, primero debemos convertir todas las unidades a hl.

Para el coche verde:

[tex] V_{1} = 3 dl*\frac{1 hl}{1000 dl} = 0,003 hl [/tex]

[tex] V_{2} = 75 ml*\frac{1 hl}{100000 ml} = 0,00075 hl [/tex]    

Para el coche azul:    

[tex] V_{3} = 13 cl*\frac{1 hl}{10000 cl} = 0,0013 hl [/tex]

[tex] V_{4} = 5 ml*\frac{1 hl}{100000 dl} = 0,00005 hl [/tex]    

Ahora, para encontrar el volumen total debemos sumar todos los volúmenes anteriores:

[tex] V_{T} = V_{1} + V_{2} + V_{3} + V_{4} = 0,003 hl + 0,00075 hl + 0,0013 hl + 0,00005 hl = 0,0051 hl [/tex]

Por lo tanto, Juan necesita 0,0051 hl en total.

2. Luego, para saber si tendrá suficiente con una lata de medio litro, debemos convertir el volumen total de hl a l:

[tex] V_{T} = 0,0051 hl*\frac{100 l}{1 hl} = 0,51 l [/tex]

Entonces, dado que el volumen total es 0,51 litros Juan no tendrá suficiente con una lata de medio litro porque necesita cubrir 0,01 litros más.

Answer: 37, [tex]\frac{x+2}{7}[/tex]

Step-by-step explanation:

Given

[tex]f(x)=7x-2\\g(x)=x^2+1\\h(x)=3x[/tex]

now,

[tex]g(h(x))=(3x)^2+1\\g(h(x))=9x^2+1[/tex]

for x=2

[tex]g(h(2))=9\cdot (2)^2+1\\g(h(2))=36+1\\g(h(2))=37[/tex]

Inverse of [tex]f(x)[/tex] is given by

[tex]y=7x-2\\x=\dfrac{y+2}{7}\\\\f^{-1}(x)=\dfrac{x+2}{7}[/tex]

Step-by-step explanation:

The bias in the report is that households without a vehicle were not surveyed.

• A bias in a statistical research may be occur when the sample used is not entirely representative of the population. The research carried out above was to evaluate the number of households with more Than one car, the sampling frame should not only include the households with cars but the entire household in the town.

• The fact that the random sample were Drivers at the gas station, exempts those households without cars because those without cars cannot drive to a gas station.

• The sample is sufficiently large.

The scenario also states that, the samples were chosen randomly.

Hence, the bias is that household without cars were exempted from the survey.

Answer:

17.8

Step-by-step explanation:

We can find this because we know that to make a cube, we need to do [tex]c*c*c[/tex] or [tex]c^3[/tex]. With this, we can simplify our equation (by taking the root of both sides) to [tex]c=\sqrt[3]{5639.752}[/tex] or 17.8.

Here's the solution,

Volume of wall :

=》total bricks × volume of each brick

=》1200 × 0.075 m³

=》90 m³

volume of wall :

=》lenght × width × height

=》25 × 9 × width

=》225 × width

now, by equating the volumes, we get

( since they are volume of same wall )

=》225 × width = 90

=》width = 90 ÷ 225

=》width of wall = 0.4 m
