x= -24 (c)

Answer:

64

you are distrbuting  both the 8 which =64

Step-by-step explanation:

See the steps below:)

Answer:

Step-by-step explanation:

8(5+3)

You distribute what's in the Parentheses

8 x 5 = 40 and 8 x 3 = 24

40+24 = 64

Answer:

t = 6

y = -12

Step-by-step explanation:

-9(t – 2) = 4(t – 15)

-9t + 18 = 4t - 60

-13t = -42

t = 6

10(2y + 2) – y = 2(8y -8)

20y + 20 - y = 16y - 16

3y = -36

y = -12

Answer:

Volume of a cone is v = πr²(h/3), So i think you just substitute the values for every step, 2nd step maybe v = 3.14(2²)(12/3) and then 3.14(4)(12/3) and then 12.56(12/3) then you divide by 3, then simplify from there. The radius =2 and the height is 12. Volume is about 50.24 if you use 3.14 as pi

Step-by-step explanation:

The equation of a cone is v = πr²(h/3), radius is 1/2 of diameter.

Answer:

I have no idea how to fill in the blanks so I'm just gonna write the answer step by step :/

r = 2

h = 12

[tex]V=\pi r^2\frac{h}{3}[/tex]

[tex]V=\pi (2)^2(\frac{12}{3} )\\\\=\pi(4)(\frac{12}{3} )\\\\=\pi (4)(4)\\\\=\pi (16)[/tex]

estimate using 3.14 for pi:

≈ 50.24 [tex]m^3[/tex]

Answer:

[tex] x =2[/tex]

Step-by-step explanation:

Given :-

And we need to find out the value of x. Well there is no specific method to solve the equation .This can be only done using the " Trial and error" Method.

[tex]\implies {3}^{2} + {4}^{2} = {5}^{2} [/tex]

Verification :-

[tex]\implies {3}^{2} + 4^2 = 9+16=25=\boxed{5^2}[/tex]

So , the value of x is 2 . We can here prove that , x does not have other roots other than 2 . For that , divide the both sides of equation by [tex]5^x[/tex] , we have ,

[tex]\implies \dfrac{{3}^{x} + {4}^{x}}{5^x} = \dfrac{{5}^{x}}{5^x} [/tex]

[tex]\implies \bigg( \dfrac{3}{5}\bigg)^x+ \bigg( \dfrac{4}{5}\bigg)^x = 1 [/tex]

That is ,

[tex]\implies \bigg( \dfrac{3}{5}\bigg)^x+\bigg( \dfrac{4}{5}\bigg)^x > \bigg( \dfrac{3}{5}\bigg)^2 +\bigg( \dfrac{4}{5}\bigg)^2 [/tex]

Subsequently :-

[tex]\implies \bigg( \dfrac{3}{5}\bigg)^x+\bigg( \dfrac{4}{5}\bigg)^x > 1 [/tex]

[tex]\implies \bigg( \dfrac{3}{5}\bigg)^x+\bigg( \dfrac{4}{5}\bigg)^x < \bigg( \dfrac{3}{5}\bigg)^2 +\bigg( \dfrac{4}{5}\bigg)^2 [/tex]

Subsequently :-

[tex]\implies \bigg( \dfrac{3}{5}\bigg)^x+\bigg( \dfrac{4}{5}\bigg)^x <1[/tex]

Hence 2 is the root of the given equation.

Answer:

an electron moving into the nucleus

When an electron moved to an excited state, it will produce light. So, the correct option is (D).

Light are commonly referred as Electromagnetic Radiation which can be detected by the human eye. This spectrum is extremely broad which ranges from low energy radio waves with wavelengths that are to high energy gamma rays with wavelengths which are less than 1x [tex]10^-^1^1[/tex].

The largest electromagnetic waves having wavelengths from a few centimeters to over 100 meters called as radio waves while the smallest electromagnetic waves having wavelengths which is the size of an atomic nucleus are called gamma rays. In between these waves, microwaves, infrared light, visible light, ultraviolet light and X-rays. It refers to visible radiant energy.

Light is emitted when an electron jumps from a higher orbit to a lower orbit and absorbed when it jumps from a lower to higher orbit which causes to produce light.

Thus, when an electron moved to an excited state, it will produce light. So, the correct option is (D).

Answer:

what numbers ?

Step-by-step explanation:

Answer:

Slope = 3

Y-intercept = 3

Equation = 3x + 3

Step-by-step explanation:

Slope = Change in y / Change in x

Change in y = +3

Change in x = +1

Slope = 3/1

Slope = 3

Y-intercept = y-value where x = 0

Y-intercept: x = 0; y = 6-3

Y-intercept = 3

Equation: y = mx + b

m = slope

b = y-intercept

Equation: y = 3x + 3

Answer:

The average of each day is 6 fishes

Step-by-step explanation:

Given

See attachment for dot plot

Required

Determine the true statement

For day 1, we have:

[tex]Fis hes = 3 + 6 + 6 + 6 + 6 + 3[/tex]

[tex]Fis hes = 30[/tex]

[tex]Participants = 6[/tex]

The mean is:

[tex]Mean = \frac{Fish es}{Participants}[/tex]

[tex]Mean = \frac{30}{6}[/tex]

[tex]Mean = 5[/tex]

For day 2, we have:

[tex]Fis hes = 3 + 3 + 4 + 6 + 7 + 7[/tex]

[tex]Fis hes = 30[/tex]

[tex]Participants = 6[/tex]

The mean is:

[tex]Mean = \frac{Fish es}{Participants}[/tex]

[tex]Mean = \frac{30}{6}[/tex]

[tex]Mean = 5[/tex]

Answer:

80

Step-by-step explanation:

This is calculated as:

(Number of ducks with bands × Number of examined ducks)/ Number of ducks found with leg band

= Number of ducks with bands = 12 ducks

Number of examined ducks = 20 ducks

Number of ducks found with leg band = 3 ducks

Hence:

12 × 20/3

= 240/3

= 80 ducks

Therefore, 80 ducks used the ponds

the answer is 144 square inches

Answer:

Step-by-step explanation:

1). From the triangle given in the figure,

   m∠BAD = 26°

   By applying tangent rule in ΔADB,

   tan(∠BAD) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]

   tan(26°) = [tex]\frac{BD}{AD}[/tex]

   BD = 21[tan(26°)]

   BD = 10.24

   By applying sine rule in ΔBDC,

   sin(52°) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]

   sin(52°) = [tex]\frac{10.24}{x}[/tex]

    x = [tex]\frac{10.24}{\text{sin}(52)}[/tex]

    x = 12.99

    x ≈ 13.0 units

2). By applying cosine rule in ΔADB,

    cos(39°) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]

    cos(39°) = [tex]\frac{BD}{50}[/tex]

    BD = 50cos(39°)

    BD = 38.86

    By applying sine rule in ΔBDC,

    sin(24°) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]  

    sin(24°) = [tex]\frac{38.86}{x}[/tex]

               x = [tex]\frac{38.86}{\text{sin(24)}}[/tex]

               x = 95.54

              x ≈ 95.5 units

Answer:

[81 is the missing number.]

Step-by-step explanation:

7+x=88

Let us substitute the mixing number as x.

To find a variable we must ISOLATE it.

To isolate in this situation, we must remove the 7.

We must subtract 7 from both sides, to isolate x. like this-

7-7+x=88-7

This results in,

x=81

So this missing number or (x) is equal to 81

Value of x --> 15°

Step-by-step explanation:

(2x + 60°) and 6x lie on a straight line. So, they form a linear pair. Their sum gives 180°.

---> (2x + 60°) + 6x = 180°

     2x + 60° + 6x = 180°

     8x + 60° = 180°

     8x = 180°- 60°

     8x = 120

      x = [tex]\frac{120}{8}[/tex]

The solution is, square root of 225/16  is 15/4.

A square root of a number is a value that, when multiplied by itself, gives the number. In mathematics, a square root of a number x is a number y such that y² = x; in other words, a number y whose square is x.

For example, 4 and −4 are square roots of 16, because 4² = ² = 16.

here, we have,

225/16

=15^2/4^2

so, square root of 225/16

=√15^2/4^2

=15/4

Hence, The solution is, square root of 225/16  is 15/4.
