Answer 1

Answer:

Answer:

Cone is equal to 3, white ice cream is equal to 2, and the pink is equal to 1.

Step-by-step explanation:

Something times something times something is equal to 27, and 27=3x is equal to 3. The cone is equal to 3.

3+3=6, and since 10-6 =4, 4=2x, so the white ice cream is equal to 2.

3+3+3=9, and 2+2=4, 9+4=13, so 15-13=2, and 2=2x, so the pink ice cream is equal to 1.

Sorry if it was a little cofusing.

The diameter of the jar of marshmallow fluff is 5in. What is the area of the jar opening? Please show the steps how to do that.

Answers

The opening of the jar is a circle.

The area of any circle is (pi) x (radius)²

What's the radius of the jar ?
Well, the diameter is 5 inches.
Radius = 1/2 of the diameter = 2.5 inches.

So Area = (pi) x (2.5 inches)² =

(3.14) x (6.25 square inches) = 19.625 square inches.

Final answer:

The area of the jar opening, being a circle, is found by using the formula A = pi*r^2. With a diameter of 5, the radius is 2.5. So the area is approximately 3.14 * 2.5^2 = 19.625 square inches.

Explanation:

To calculate the area of the jar opening, which is a circle, you need to know the radius of the circle. The given information is that the diameter is 5 inches. The radius is half the diameter, therefore, in this case, the radius is 5/2 = 2.5 inches. Then to find the area, you use the formula for the area of a circle: A = pi * r^2, where pi is approximately 3.14 and r denotes the radius. Substituting the known values into the formula, we have Area = 3.14 * (2.5^2) = 3.14 * 6.25 = 19.625 square inches. Thus, the area of the jar opening is approximately 19.625 square inches.

What are the solutions of the equation x4 + 6x2 + 5 = 0? Use u substitution to solve.x = i and x = i 5

X=+ i and x i 5

x=+ -1 and x= + -5

x= -1 and x= + - 5

Answers

The solutions of the equation are $x=\pm i, x=\pm √(5)i$

Explanation:

Given that the equation is $x^(4)+6 x^(2)+5=0$

We need to determine the solutions of the equation.

Let us substitute $x^(2) =u$ and $x^4=u^2$

Thus, the equation becomes,

$u^(2)+6 u+5=0$

Factoring the equation, we get;

$(u+1)(u+5)=0$

$u=-1, u=-5$

Substituting back $x^(2) =u$ and solve for x.

First, we shall substitute $u=-1$

Thus, we get;

$x^(2) =-1$

$x=√(-1)$

$x=\pm i$

Similarly, substituting $u=-5$ , we get;

$x^(2) =-5$

$x=√(-5)$

$x=\pm √(5)i$

Thus, the solutions of the equation are $x=\pm i, x=\pm √(5)i$

A model spaceship cost 15.99 before tax the tax on the model spaceship is 8%

Answers

Hi there!

The tax on the spaceship is 8% of 15.99

The word "of" is the same thing as a multiplication sign.

8% of 15.99 = 8% × 15.99

8% = 0.08

8% × 15.99 = 0.08 × 15.99

0.08 × 15.99 = 1.2792

15.99 + 1.2792 = 17.2692

Your answer is: The final price including tax for the spaceship is about $17.27

There you go! I really hope this helped, if there's anything just let me know! :)

15.99 * .8 = 12.79

15.99 + 12.79 = 28.78

the answer is $28.78 :)
