9/20 + 2 9/10 or nine twentieths plus two and nine tenths

Answers

Answer 1

So, first we have to put in an equation

9/20+ 2 9/10

multiply 9/10 by 2

So you get 9/20+ 2 18/20

Add the fractions together and you'll get 26/20

since their isn't a whole number a whole number it's just 2 and 26/20 reduce it to

2 and 9/5

I hope this is right. This is how I was taught.

If you draw an altitude of the right triangle, you get that the legs are (18/2)=9 and the height (which I'll call x) and a hypotenuse of 18.

By the Pythagorean theorem,

[tex] {9}^{2} + {x}^{2} = {18}^{2} \\ 81 + {x}^{2} = 324 \\ {x}^{2} = 243 \\ x = \sqrt{243} = 9 \sqrt{3} [/tex]

A 24-inch diameter pizza is cut into eight slices. What is the area of one slice?

Answers

Answer:

Area of a slice = Area of the pizza ÷ 8

Therefore the area of the pizza equals:

AreaPizza = π r^2 ( r = diameter ÷ 2)

= π 6^2

= 113.097

AreaSlice = AreaPizza ÷ 8

= 113.097 ÷ 8

find the zeros of x^4-10x^3+35x^2-50x+24=0

Answers

Photo is attached.

Sorry my writing is so messy, but basically I found all possible zeros by finding the factors of 24:

(Positive or negative) 1,2,3,4,6,8,12,24

Then, using remainder theorem (when you plug potential zeros into the x values to see if the equation will equal zero) I found out that 1 made the equation equal zero, and therefore was a zero.

Then I used synthetic division to make the equation smaller (I also used 2 because I found out that it was a zero using remainder theorem, same as how I found out 1)


Once I divided it small enough to factor, I simply factored it to find the last 2 zeros

A triangle has an angle that measures 10°. The other two angles are in a ratio of 3:14. What
are the measures of those two angles?

Answers

Step-by-step explanation:

Need to FinD :

We have to find the measures of other two angles of triangle.

[tex] \red{\frak{Given}} \begin{cases} & \sf{The\ measure\ of\ one\ angle\ of\ traingle\ is\ {\pmb{\sf{10^{\circ}}}}.} \\ & \sf{The\ other\ two\ angles\ are\ in\ the\ ratio\ of\ {\pmb{\sf{3\ :\ 14}}}.} \end{cases}[/tex]

We know that,

The other two angles of triangle are in the ratio of 3 : 14. So, let us consider the other two angles of the triangle be 3x and 14x.

Angle sum property,

The angle sum property of triangle states that the sum of interior angles of triangle is 180°. By using this property, we'll find the other two angles of the triangle.

[tex]\rule{200}{3}[/tex]

[tex] \sf \dashrightarrow {10^{\circ}\ +\ 3x\ +\ 14x\ =\ 180^{\circ}} \\ \\ \\ \sf \dashrightarrow {10^{\circ}\ +\ 17x\ =\ 180^{\circ}} \\ \\ \\ \sf \dashrightarrow {17x\ =\ 180^{\circ}\ -\ 10^{\circ}} \\ \\ \\ \sf \dashrightarrow {17x\ =\ 170^{\circ}} \\ \\ \\ \sf \dashrightarrow {x\ =\ \dfrac{\cancel{170^{\circ}}}{\cancel{17}}} \\ \\ \\ \dashrightarrow {\underbrace{\boxed{\pink{\frak{x\ =\ 10^{\circ}.}}}}_{\sf \blue {\tiny{Value\ of\ x}}}} [/tex]

∴ Hence, the value of x is 10°. Now, let us find out the other two angles of the triangle.

[tex]\rule{200}{3}[/tex]

Second AnglE :

3x3 × 1030°

∴ Hence, the measure of the second angle of triangle is 30°. Now, let us find out the third angle of triangle.

[tex]\rule{200}{3}[/tex]

Third AnglE :

14x 14 × 10140°

∴ Hence, the measure of the third angle of the triangle is 140°.

What is a prism?

A prism is a three-dimensional object.

There are triangular prism and rectangular prism.

We have,

To solve this problem, we first need to calculate the original surface area of the complex solid.

The complex solid is composed of two rectangular prisms, one with dimensions 9.8 ft × 6.5 ft × 8.1 ft and one with dimensions 10.6 ft × 4.3 ft × 6.5 ft.

The surface area of the first rectangular prism is:

2(9.8 × 6.5) + 2(9.8 × 8.1) + 2(6.5 × 8.1) = 464.82 ft²

The surface area of the second rectangular prism is:

2(10.6 × 4.3) + 2(10.6 × 6.5) + 2(4.3 × 6.5) = 411.22 ft²

So the total original surface area of the complex solid is:

464.82 + 411.22 = 876.04 ft²

Now we need to find the new surface area, which is exactly 14 times the original surface area.

Therefore, we can write:

New surface area = 14 × original surface area

New surface area = 14 × 876.04

New surface area ≈ 12264.56 ft²

Thus,

The new surface area is approximately 12264.56 ft².

Let f(x) = 3 * sqrt(x) + 7. Define g$to be the inverse of f.

What is the value of g(g(f(f(f(36)))))?

Answers

By using the definition of inverse functions, we will see that:

g(g(f(f(f(36))))) = f(36) = 25.

What are inverse functions?

Two functions f(x) and g(x) are inverses if:

f( g(x) ) = x

g( f(x) ) = x

Then we can rewrite:

g(g(f(f(f(36)))))

First, we can see that:

g(f(f(f(36)))) = f(f(36))

Replacing that in our expression, we get:

g(g(f(f(f36))))) = g(f(f(36)))

And the above expression is equal to f(36), to be sure of that, let's replace:

u = f(36)

Then we can rewrite:

g(f(f(36))) = g(f(u))

And by definition, the above thing is equal to u:

g(f(u)) = u = f(36).

Finally, we conclude that:

g(g(f(f(f(36))))) = f(36) = 3*√36 + 7 = 3*6 + 7 = 25
