Hello
I need to figure out this equation for homework and I don't understand how you get the answer.

(5y^2)^-2

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:

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:

x = 6

Step-by-step explanation:

8x + 2 + 70 + 60 = 180

8x + 132 = 180

8x = 48

x = 6

Answer:

6

Step-by-step explanation:

multiple 30× .20% which equals 6. Then you will add 30 +6=36. So, Lane will do a total of 36 push-ups everyday

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]

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.

It is C

In problem C X is still being multiplied by the other variable y, and also it is still multiplying the 7 too, The other questions do not factor in the multiplication required meaning that the only answer that could be applied would be C.

Answer:

∠A = 175∘

Step-by-step explanation:

∠A = ∠B

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:

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.

A percentage is essentially a fraction, but lazily written. Think of a percent as 25/100, or 0.25.

Now multiply the two.

0.25x5/8.

We need to convert 5/8 to a decimal, which is 0.625.

0.25x0.625=0.15625.

Now convert the decimal to a fraction, which is 5/32.
