Answer:

x=16

Step-by-step explanation:

The opposite angles will always be supplementary

<K + < M = 180

47+ 7x+21 = 180

Combine like terms

7x+68 = 180

Subtract 68

7x = 180-68

7x = 112

Divide by 7

7x/7 = 116/7

x =16

Answer:

The value of x is 64.

Step-by-step explanation:

The base angles of an isoceles triangle are congruent.

[tex]x + 58 + 58 = 180[/tex]

[tex]\large{\sf \boxed{ \sf 9.09 \ \%}}[/tex]

Explanation:

Let the price be p,

When the price is increased by 10%,

Increased price = (100% + 10%) × p = 1.1p

So reduction percentage:

[tex]\rightarrow \sf \dfrac{1.1p - p}{1.1p} \ x \ 100[/tex]

[tex]\rightarrow \sf \dfrac{0.1p}{1.1p} \ x \ 100[/tex]

[tex]\rightarrow \sf 9.090909091 \% \quad \approx \quad 9.09 \% \quad (rounded \ to \ nearest \ hundredth)[/tex]

                                                  Elimination:

-4x - 2y = -18                            -4x - 2y   = -18

x + 3y   = 8        | ×4   ------>      4x + 12y = 32  +

                                                          10y = 14

                                                              y = 1,4

x + 3y = 8

x + 3(1,4) = 8

x + 4,2 = 8

x = 3,8

Stefofp-by-step explanation:

Simplify the following:

(-6 x^3 y^4 + 9 x^8 y^2)/(3 x y)

Factor 3 x^3 y^2 out of -6 x^3 y^4 + 9 x^8 y^2:

(3 x^3 y^2 (-2 y^2 + 3 x^5))/(3 x y)

(3 x^3 y^2 (-2 y^2 + 3 x^5))/(3 x y) = 3/3×(x^3 y^2 (-2 y^2 + 3 x^5))/(x y) = (x^3 y^2 (-2 y^2 + 3 x^5))/(x y):

(x^3 y^2 (-2 y^2 + 3 x^5))/(x y)

Combine powers. (x^3 y^2 (-2 y^2 + 3 x^5))/(x y) = x^(3 - 1) y^(2 - 1) (-2 y^2 + 3 x^5):

x^(3 - 1) y^(2 - 1) (-2 y^2 + 3 x^5)

3 - 1 = 2:

x^2 y^(2 - 1) (-2 y^2 + 3 x^5)

The number of seconds taken by the fourth team to complete his part of the race is 45.116 seconds.

It simply means to deduct something from the object or number of group, place, etc. Subtraction means to take away from the group or a number of objects.

Four athletes from the Republic of Korea competed in a team wheelchair race at the Paralympic Games.

The team finished the race in a total of 190.729 seconds.

First team member: 46.685 seconds

Second team member: 48.869 seconds

Third team member: 49.33 seconds

Then the number of the seconds is taken by the fourth team will be

Let x be the number of the second taken by the fourth team.

Then we have

x + 46.685 + 48.869 + 49.33 = 190.729

                            x + 144.884 = 190.729

                                             x = 45.116

The velocity that the coaster must have at the top of a 50-foot hill to achieve a velocity of 57 feet per second is 7 feet/second.

Velocity is the rate of change of its position with respect to time.

[tex]V = \dfrac{dy}{dt}[/tex]

Given the velocity(v) in feet per second of a roller coaster at the bottom of a hill is related to the vertical drop(h) in feet and the velocity(v°) in feet per second of the coaster at the top of the hill by the formula v°=√(v²-64h).

Therefore, the velocity of the coaster at the top should be,

[tex]v^o=\sqrt{(v^2-64h)}\\\\v^o=\sqrt{[57^2-(64\times 50)]}\\\\v^o=\sqrt{49}\\\\v^o = 7\rm\ feet/second[/tex]

Hence, the velocity that the coaster must have at the top of a 50-foot hill to achieve a velocity of 57 feet per second is 7 feet/second.

4v points in the same direction as v, so all you need to do is normalize v.

Simply multiply it by the reciprocal of its magnitude:

[tex]v = (-1, 4, 2) \implies \|v\| = \sqrt{(-1)^2 + 4^2 + 2^2} = \sqrt{21}[/tex]

[tex]\implies \dfrac{v}{\|v\|} = \dfrac{(-1,4,2)}{\sqrt{21}} = \left(-\dfrac1{\sqrt{21}}, \dfrac4{\sqrt{21}}, \dfrac2{\sqrt{21}}\right)[/tex]

Answer:

49:25

Step-by-step explanation:

When you have a side length ratio given, the area ratio will be the side length ratio squared.

This can be thought of quite easily, say you have 1 square with a side length of 7 and another square with a sidelength 5.

Of course the squares have a side length ratio of 7:5

The area of the first square is 7*7 = 49

The area of the second square is 5*5 = 25

Then clearly the ratio of the areas is 49:25

The volume of the tank of water is 653.12 cubic meters.

For a cylinder of height H and diameter D, the total volume is given by:

[tex]V = 3.14*(D/2)^2*H[/tex]

In this case, we know that:

D = 8m

H = 13m

Replacing that in the above equation:

[tex]V = 3.14*(8m/2)^2*13m = 653.12 m^3[/tex]

So the volume of the tank of water is 653.12 cubic meters.
