Find pairs of natural numbers:
1) xy+y=4
2) x²+ y²= 13

Answer:

121degrees

Step-by-step explanation:

For a quadilateral inscribed in a circle, the sum of its opposite angles is 180degrees. Hence;

<B + <D = 180

x -15 + 74 = 180

x + 59 = 180

x = 180 - 59

x = 121 dgrees

Hence the value of x is 121degrees

Answer:

[tex]2x(x-2y)(x+5)[/tex]

Step-by-step explanation:

Factor out any GCFs before proceeding!

[tex]2x(x^2+5x-2xy-10y)[/tex]

Split the parenthesis into two.

[tex]2x((x^2+5x)-(2xy-10y))[/tex]

Factor out GCFS of both again!

[tex]2x(x(x+5)-2y(x-5))[/tex]

Now that you have two matching equations, you can cancel one out!

[tex]2x(x-2y)(x+5)[/tex]

Answer:

100.48

Step-by-step explanation:

Surface area of a cylinder = [tex]2\pi r^2+2\pi rh[/tex]

Where r = radius and h = height

We are given the diameter ( 4 cm ) and the height ( 6cm )

To convert diameter to radius we simply divide by 2 ( because radius = half the length of the diameter )

4 / 2 = 2 Thus, r = 2

Now we plug in the values of the radius and height into the surface area of a cylinder formula ( note we must use 3.14 for π as the question says to. not doing so can result in a wrong answer )

[tex]SA=2(3.14)(2^2)+2(3.14)(2)(6)\\2^2=4\\4*3.14=12.56\\12.56*2=25.12\\\\2*3.14=6.28\\6.28*2=12.56\\12.56*6=75.36\\\\75.36+25.12=100.48\\SA=100.48cm^2[/tex]

Step-by-step explanation:

You're right its the answer is C

Answer:

You end up at point (7,5).

Step-by-step explanation:

Starting point:

The coordinates of the starting point are: x = 4, y = 6.

So

(4,6).

Move 3 units right:

Moving 3 units right is adding 3 to the x-coordinate. So

x = 4 + 3 = 7

(7,6).

Move 1 unit down:

Moving 1 unit down is subtracting 2 from the y-coordinate. So

y = 6 - 1 = 5.

You end up at point (7,5).

Answer:

Answer:

2

Step-by-step explanation:

-3x ≤ -5

if we divide for a negative number we have to change the sign of the inequality

x ≥ 5/3

5/3 = 1,666

so the nearest integer number is 2

Answer:2

Step-by-step explanation:

Answer:

Solution given:

Y=90°

∠X=73°.

∠ZWY=80°

and XW=80.

ZY=?

We know that

In right angled triangle ∆ XYZ

Tan 73=[tex] \frac{p}{h} [/tex]

3.27=[tex] \frac{yz}{xy} [/tex]

3.27×[xy]=yz

xw+wy=[tex] \frac{yz}{3.27} [/tex]

wy=[tex] \frac{yz}{3.27} [/tex]-80...........(1)

again

In right angled triangle WYZ

Tan 80=[tex] \frac{yz}{wy} [/tex]

5.67×wy=yz

wy=[tex] \frac{yz}{5.67} [/tex]

yz=5.67×wy............................................(2)

Equating equation 1&2

[tex] \frac{yz}{5.67} [/tex]=[tex] \frac{yz}{3.27} [/tex]-80

[tex] \frac{yz}{3.27} [/tex]-[tex] \frac{yz}{5.67} [/tex]=80

5.67yz-3.27yz=80*5.67*3.27

2.4yz =1483.272

yz=[tex] \frac{1483.272}{2.4} [/tex]

yz=618.03

:.y=618.03unit.the length of ZY to the nearest 100th is 618.

Step-by-step explanation:

let,

p(A)={1,2,3,4}

p(B)={3,4,5,6}

p(AnB)={3,4}

now,

LHS=RHS. proved.

Answer: 36 cubic feet

Step-by-step explanation:

Answer:

x = 20

Step-by-step explanation:

x/10 = 2

Multiply each side by 10

x/10 * 10 = 2*10

x = 20

Answer:

y = -6x-8

Step-by-step explanation:

Step-by-step explanation:

exterior angle

-> (4x + 6)° = x + 102°

3x = 102° - 6°

3x = 96°

x = 32°

4x + 6°= 4×32° + 6° = 128 + 6 = 134°

Answer:

S = E - 3

Sue is 53 inches tall.

Step-by-step explanation:

Let Sue's age be represented by S and Ed's by E

Equation:

S = E - 3

E = 56 inches

S = 56 - 3 = 53 inches

Answer:

The probability that a house has a backyard given that has a garage is 76.60%.

Step-by-step explanation:

Given that in New England 47% of the houses have a garage and 36% of the houses have a garage and a backyard, to determine what is the probability that a house has a backyard given that has a garage the following crossed multiplication must be performed:

47 = 100

36 = X

(36 x 100) / 47 = X

3,600 / 47 = X

76.5957 = X

Therefore, the probability that a house has a backyard given that has a garage is 76.60%.

Answer:

The answer is the 3rd one.

Answer:

arcBC = 140degrees

Step-by-step explanation:

From the given digaram;

Angle at the center is twice angle at the circumference

Hence;

m<CAB = 2(m<CDB)

m<CAB = 2 * 35

m<CAB = 70degrees

Also;

m<CAB = 1/2 arcBC

70 = 1/2arcBC

arcBC = 70*2

arcBC = 140degrees

Answer:

commutative properties satisfies the property.

The goal is to find the radius of a circle which also helps to get the diameter. Finding the center helps to measure and know the circumference.

Answer:
