Can someone please tell me the answer and explain how to do this, no links please thank you

Answer:

r = 7

y = -2

Step-by-step explanation:

9r + 2y = 59 (Multiply this by 5)

2r + 5y = 4   (Multiply this by -2)

45r + 10y = 295

-4r - 10y = -8

41r = 287

r = 7

2r + 5y = 4

2(7) + 5y = 4

14 + 5y = 4

5y = 4 - 14

5y = -10

y = -2

We need to determine the equation of the circle graphed in the attachment. Firstly we know the Standard equation of a Circle as ,

[tex]\sf\implies (x-h)^2+(y-k)^2 = r^2[/tex]

Let's find out the radius . As ,

[tex]\sf\implies r = \sqrt{ ( 6-4)^2+(2+2)^2} \\\\ \sf\implies r =\sqrt{ 2^2 + 4^2}\\\\\sf\implies r = \sqrt{ 4 + 16 }\\\\\sf\implies \red{r =\sqrt{20}}[/tex]

Substituting the respective values :-

[tex]\implies ( x - 4 )^2 + \{y - (-2)\}^2 = (\sqrt{20})^2 \\\\\sf\implies ( x - 4 )^2 + \{y + 2 \}^2 = 20 \\\\\sf\implies x^2+16-8x + y^2+4+4y = 20 \\\\\sf\implies \red{x^2+ y^2 - 8x + 4y = 0 }[/tex]

[tex]\boxed{\pink{\tt Equation \to x^2+ y^2 - 8x + 4y = 0 }}[/tex]

Answer:

y<-1

Step-by-step explanation:

This exponential function will never approach y=-1, but it goes "under" the line of -1, so it is y<-1

3/4m(4m+16n) + m/n open the bracket of equation,

3/4m(4m+16n) + m/n = 3+ 12n/m + m/n

now multiply and devide by mn on RHS,

3/4m(4m+16n) + m/n = (3mn+12n²+m²)/mn

Step-by-step explanation:

just add all of them and divide it by six.

Answer:

The answer is "triangle ABC is not a right triangle".

Step-by-step explanation:

For a right-angle triangle:

Its square upon on longest or triangular edges is equivalent to the total of the other two squares

Its parameters indicated throughout the question are;

Square of lateral length [tex]A = 7 \ inch^2[/tex]

The square of lateral length [tex]B = 18 \ inch^2[/tex]

The square of lateral length [tex]C=27\ inch^2[/tex]

Thus, the longest side is C, as well as the size [tex]inch^2[/tex] of the squares of its two sides, is[tex]7 + 18 = 25 \ inch^2[/tex], lower than square [tex]C = 27\ inch^2[/tex], hence, the ABC triangle is not correct. Its longest edge is consequently C.

Step-by-step explanation:

angle 4

110-180

=70

angle 5

angle = 110

angle 6

110-180=

70

Answer:

Step-by-step explanation:

angle 4+angle 3=180 degree(being linear pair)

angle 4+110=180

angle 4=180-110

angle 4=70 degree

angle 4=angle 5(being alternate interior angle)

70 degree=angle 5

angle 5+angle 6=180 degree(being linear pair)

70+angle 6=180

angle 6=180-70

angle 6=110 degree

Answer:

∡J and ∡K are complementary

Step-by-step explanation:

since ∡L is a right angle, that means it measures 90 degrees

since there are a total of 180 degrees inside a triangle, angles J and K must add up to 90 which means they are complementary

Answer:

TO find the answer, first you have to find the formula for volume of a cone-

The formula is

V= 1/3 times base times height

So V= (1/3) (pi3^2) (12)

V= 113.04

By the way for the base you have to find the volume of a circle. I divided the diameter by 2 to find the radius.

and pi is 3.14

Let the three items be M, Y and P.

n{M ∩ Y} only = 4-3 = 1

n{M ∩ P) only = 5-3 = 2

n{ Y ∩ P} only = 2

n{M} only = 12-(1+3+2) = 6

n{Y} only = 10-(1+2+3) = 4

n{P} only = 14-(2+3+2) = 7

n{M∩P∩Y} = 3

Answer:

7.18

Step-by-step explanation

4* COS(23) = 3.682

3.5+3.682 = 7.182

Answer:

See below.

Step-by-step explanation:

See the attached chart that shows all outcomes for two dice.

There are 36 possible outcomes, all equally likely (if the dice are fair!).

The probability of getting a sum of 2 is  1/36 (only one way to get 2: both dice show 1).

The probability of getting a sum of 3 is  2/36 = 1/18.

The probability of getting a sum of 7 is 6/36 = 1/6 (the most likely sum!)

(Notice how all the sum = 7 outcomes like on a diagonal in the chart?)

The probability of getting a sum of 11 is  2/36 = 1/18.

The probability of getting a sum of 12 is 1/36.

Answer:

6:55 p.m

Step-by-step explanation:

Hour connects with hour therefore, 5 + 1 = 6

Minutes connects with minutes thus, 10 + 45 = 55

Hence it being 6:55 p.m when the movie finishes if it starts at 5:10 p.m.

Answer:

46.67 in

46.67 in

Step-by-step explanation:

the value of the hypotenuse (length of the ladder ) is given. We are to determine the value of the opposite side (distance from the ground) and adjacent side ( distance from the wall)

(distance from the ground = sin 45 = opposite / hypotenuse

0.7071 = x/66

x = 66 x 0.7071 = 46.67

distance from the wall = cos 45 = adjacent / hypotenuse

0.7071 = x/66

x = 66 x 0.7071 = 46.67
