No.

Step-by-step explanation:

[tex]a^{2} +b^{2} = c^{2}[/tex]

4^2 is 16. 55^2 is 3025. 16 plus 3025 is 3041. 73^2 is 5329. 5329 does not equal 3041.

The equation [tex]\rm \sqrt{x^2 + 81} = x + 10[/tex] is equivalent to [tex]\rm x^2 + 81 = x^2 + 20x + 100[/tex]. Then the correct option is D.

It is a polynomial that is equal to zero. Polynomial of variable power 2, 1, and 0 terms are there. Any equation having one term in which the power of the variable is a maximum of 2 then it is called a quadratic equation.

The equation is given below.

[tex]\rm \sqrt{x^2 + 81} = x + 10[/tex]

Squaring both sides, we have

[tex]\rm (\sqrt{x^2 + 81})^2 = (x + 10)^2\\\\x^2 \ \ +\ \ 81 \ \ = x^2 + 20x + 100[/tex]

Thus, the equation [tex]\rm \sqrt{x^2 + 81} = x + 10[/tex] is equivalent to [tex]\rm x^2 + 81 = x^2 + 20x + 100[/tex]. Then the correct option is D.

Answer:

5

Step-by-step explanation:

First of all, we have a lot of different forms of part/whole's. We have a fraction, a percentage, and a number. How do we make this work???

Let's convert our percent and fraction to ounces, because that is what the question is talking about.

1/5 of 20

1/5=x/20

20=5x

/5      /5

4=x

Now lets convert our percent into ounces.

30% of 20

30/100=x/20

30(20)=100x

600=100x

/100  /100

6=x

Now we have our ounces, we now need to find what is the granola. To do that, we need to add the number of everything else, and then subtract that by the total ounces.

4+6+5=15

20-15=5

The answer would be 5 ounces of granola!

Answer:

Step-by-step explanation:

5/6 is the very definition of rational. It is a fraction.

C can found to be rational.

100 x = 656.56565656...

      x =      6.56565656...    Now subtract the 2

99x  =    650                         Divide by 99

x = 650 / 99

D is rational

23/100 = 0.23

I'm not sure about E. It should show some repeat taking place. Then we'd know.

F is rational

-5 3/8 = -43/8 which is rational.

Answer: A C D F and perhaps E

Answer:

-2x+2

Step-by-step explanation:

Answer:

-2x+2 because you would have to distribute

B5 + C9 = 164

Split the numbers.

B0 +C0 +14 = 164.

B0 + C0 = 150

B + C = 15

B cannot be 1, 2, 3, 4, or 5 because that forces C to be a two digit number and C only represents 1 digit.

B cannot be 6 or 9 because they are present.

B can only be 7 or 8. C can also be 7 or 8.

Therefore, B = 7  and C = 8, OR B = 8 and C = 7.

Answer:

A Yes, they are equivalent

Answer:

X= -10

Step-by-step explanation:

Answer:

Angle Relationship: Alternate exterior angles

x = -10

Angle measurement: 51 °

Step-by-step explanation:

These angles are located "outside" the two parallel lines but on opposite sides of the transversal, therefore they are alternate exterior angles.

Alternate exterior angles are congruent, therefore the angle must be 51 °

51 = 61 + x

subtract 61 from both sides

x = 10

Answer:

<2, <5, and <7.

Step-by-step explanation:

<2 and 72°, are vertical angles. Vertical angles are congruent. Therefore, <2 ≅ 72°.

<7 and 72° are corresponding angles. Corresponding angles are congruent, therefore, <7 ≅ 72°.

<5 and 72° are alternate interior angles. Alternate interior angles are congruent, therefore, <5 ≅ 72°.

Angles that are congruent to 72° are <2, <5, and <7.

Answer:

-16

Step-by-step explanation:

you have to first subtract 7 from 3 to get -4. then multiply 4 with -4 to get -16.

Answer:

[tex] \frac{x}{4} + 7 = 3 \\ or \: \frac{x}{4} = 3 - 7 \\ or \: \frac{x}{4} = - 4 \\ or \: x = - 4 \times 4 \\ or \: x = - 16 \\ \\ therefore \: the \: value \: of \: x \: is \: - 16.[/tex]

If Karen cut her square cardboard into two equal rectangles, the perimeter of those rectangles is 180cm. On the other hand, if the rectangle is 25 cm wide, the perimeter would be 110 cm.

The perimeter of a geometric figure is the measure of the length of all its sides. In this case, if Karen has a square of cardboard with a side of 60cm, it can be inferred that she would have two rectangles with a height of 30cm and a base of 60cm, so the perimeter would be:

On the other hand, if the rectangle has a base of 30cm and a height of 25cm, the perimeter would be:

150ft

Step-by-step explanation:

The distance from the boat to the lighthouse 321.67 ft.

Trigonometric Ratios are defined as the values of all the trigonometric functions based on the value of the ratio of sides in a right-angled.

Given that, The angle of elevation from a boat to the top of a lighthouse is 25°, the lighthouse is 150 feet tall.

Let the distance from the boat to the lighthouse be x

tan25° = 150/x

x = 150/tan25°

x = 321.67

Hence, the distance from the boat to the lighthouse 321.67 ft.
