how do i find x??????

Answer:

D. 39

Step-by-step explanation:

BC^2 = BA^2 + AC^2

BC^2 = 15^2 + 36^2

BC = square root (1521)

BC = 39

Answer:

D) 39

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean thm formula

Formula: a² + b² = c²

15² + 36² = c²

225 + 1296 = c²

1521 = c²

[tex]\sqrt{1521} =\sqrt{c^2}[/tex]

c = 39

Answer:A=2,4,6,8

One way of writing this in set builder notation could be:

A={x|2≤x≤8|x2∈N}

Which can be interpreted as:

The set A is the set of any  x  such that  2≤x≤8  such that half of  x  is a natural number ( N ).

There are many ways of writing sets in set builder notation. Which is why it can be a little confusing to learn (the syntax) at first. Once you understand what all these new mathematical symbols mean (i.e.  ∈ , | , N ), it becomes much easier to “read as a sentence”.

Here are a few more ways of writing the set  A=2,4,6,8  in set builder notation:

A={x|2≤x≤8|x∈2⋅N}

A={x|(x−2)(x−4)(x−6)(x−8)=0}

A={x|x=2p|p∈{1,2,3,4}}

A={x∈N|mod(x,2)=0|x≤8}

THANK U AGAIN <33ewiudhuids

Answer:

Step-by-step explanation:

either 1 foot or 33 ;-;

The value 5.1 feet long is a string reaching from the top of a 12-ft pole to a point on the ground that is 11 ft from the base of the pole.

In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem.

Given:

A string reaching from the top of a 12-ft pole to a point on the ground that is 11 ft from the base of the pole.

Let the value is C.

The Pythagoras' theorem,

C² = (11)² + (12)²

C² = 121 + 144

C² = 265

C = 5.1 feet.

Therefore, the value is 5.1 feet.

Answer:

89.6 meters

Step-by-step explanation:

we have to take the square root of 501.76 to find the measure of 1 side which is 22.4 which we then multiply by 4 because a square has 4 sides.

Answer:

This quadrilateral is a SQUARE.

When we plot these points, we realize that they are equal distance apart.

So, when a quadrilateral has sides that are equal distance apart, that quadrilateral is a square.

math

Answer:

Step-by-step explanation:

m∠R = 180° - 110° [Linear pair of angles are supplementary]

m∠R = 70°

m∠S = 45° [Vertically opposite angles]

By triangle sum theorem,

m∠P + m∠R + m∠S = 180°

m∠P + 70° + 45° = 180°

m∠P = 180 -115

        = 65°

Therefore, m∠A = m∠P = 65° [Vertically opposite angles]

By triangle sum theorem,

m∠B + m∠S + m∠T = 180°

m∠B + 45° + 65° = 180°

[m∠T = 65°. Since, ∠P and ∠T are corresponding angles]

m∠B = 180° - 110° = 70°

m∠C + m∠B = 180° [Linear pair of angles are supplementary]

m∠C = 180° - 70° = 110°

m∠D + m∠T = 180° [Linear pair of angles are supplementary]

m∠D + 65° = 180°

m∠D = 115°

Answer:

$1.67

Step-by-step explanation:

Given it's $1.12 for 12 eggs, we divide 1.12 by 12 to see how much it cost for 1 egg

1.12/12 = 0.093

so 0.093 cents for 1 egg

0.093x18 eggs = 1.674 = $1.67

Answer:

56/19

Step-by-step explanation:

I'll approach this using Substitution. Since 3X = 2Y, we know that 1.5X = 1Y. We can plug that into the first equation, which gives us...

2X + 5(1.5X) = 8

2X + 7.5X = 8

9.5X = 8

19X = 16

X = 16/19

While this is not 'pretty', it does match up with how most of the answers are written (four of the answers involve "nineteenths"). With this value of X, we can solve for Y...

3X = 2Y

3(16/19) = 2Y

48/19 = 2Y

24/19 = Y

With the value of X and the value of Y, we can answer the question that's asked:

2X + Y = ?

2(16/19) + 24/19 =

32/19 + 24/19 =

56/19

Final Answer: 56/19

Answer:

[tex]x = - 1[/tex]

[tex]y = - 2[/tex]

Step-by-step explanation:

[tex]3x + 2y = - 7[/tex]

[tex]2x - 5y = 8[/tex]

Apply elimination method. Let multiply the bottom equation by -3/2.

[tex]2 \times - \frac{3}{2} x = - 3[/tex]

[tex] - 5 \times - \frac{3}{2} = 7.5[/tex]

[tex]8 \times - \frac{3}{2} = - 12[/tex]

Substitute new equation and add it to the top equation

[tex]3x + 2y = - 7[/tex]

[tex] - 3x + 7.5y = - 12[/tex]

[tex]9.5y = - 19[/tex]

[tex]y = - 2[/tex]

Now plug -2 for y into any equation and solve for x.

[tex]3x + 2( - 2) = - 7[/tex]

[tex]3x - 4 = - 7[/tex]

[tex]3x = - 3[/tex]

[tex]x = - 1[/tex]
