Answer:

n = (7/3)t

Step-by-step explanation:

Represente the unknown number by n.  Then write the statement symbolically, as:

(3/7)n = t

and then solve the above equation for n by multiplying both sides by (7/3):

n = (7/3)t

Answer:

C.

Step-by-step explanation:

Radius = 16 ÷ 2 = 8

[tex]\frac{45}{360} *8^2*\pi =25.1[/tex] (3sf)

You can first find the total area of the circle which is [tex]64\pi[/tex].

Then, you can find the area of the slice of the pizza, if you take the ratio of the angle it creates with the total angle of a circle (360.)

For example, a semicircle's are would be  [tex]\frac{180}{360} *8*\pi[/tex].

Answer:

3/50

Step-by-step explanation:

Slope m = y2-y1/x2-x1

From the coordinate

x1 = 2/5, y1 = 2/3, x2 = -4/9 and y2 = 3/5

Substitute;

m = (3/5 - 2/3)/-4/9-2/3

m = (9-10/15)/(-4-6/9)

m = -1/15/-10/9

m = -1/15 * -9/10

m = 9/150

m = 3/50

Hence the slope of the line passing through the points is 3/50

Answer:

y = 2

Step-by-step explanation:

-13y + 33 = 7

add -13y to each side of the equation:

33 = 13y + 7

subtract 7 from each side:

13y = 26

divide both sides by 13:

y = 2

Answer:

40,320 different ways

Step-by-step explanation:

Here, we want to arrange 8 flags in a row

In the row, there will be 8 places

The first place has 8 flags to be chosen from

The second place has 7 and like that

So mathematically, the number of ways that we can arrange the flags is 8 factorial ways

We have this as:

8! = 40,320 different ways

Answer:

5 feet

Step-by-step explanation:

15/3 = 5

Answer:

A) 18°

Step-by-step explanation:

To find the measure of the indicated angle, we can use trigonometric ratios.

Looking at the triangle, we can see that we are given the lengths of the two legs of the triangle, but not the hypotenuse. Since we are not given the hypotenuse, the sine and cosine ratios would not work since both of them require the length of the hypotenuse. We can use the tangent ratio, since it only requires the lengths of the two legs. Remember:

[tex]tan(?)=\frac{opposite}{adjacent}[/tex]

From looking at the image, we can see that the length of the side opposite to the angle is 3, and the length of the side adjacent to the angle is 9. Thus, we can use 3 as out opposite and 9 as out adjacent:

[tex]tan(?)=\frac{3}{9}[/tex]

Now we solve for ?. Lets take the inverse tan of both sides to get rid of the tan on the left side:

[tex]?=tan^{-1}(\frac{3}{9})[/tex]

And we get:

? ≈ 18.4349488° ≈ 18°

So the answer would be 18°, or A.

I hope you find my answer to be helpful. Happy studying.

Answer:

70.49

Step-by-step explanation:

Finding the percent of a number is the same as multiplying the number by the percent in decimal form. In other words, diving the percent by (100) and then multiplying the reuslt by the number one wants to find the percent of.

69% of 102.16

= (69 / 100) * 102.16

= 0.69 * 102.16

= 70.4914

~ 70.49

Answer:

Step-by-step explanation:

[tex]69\% \:of \:102.16m\\\\\\\mathrm{Convert\:}69\%\mathrm{\:into\:a\:decimal\:\\and\:multiply\:by\:}102.16\\69\%\:=\frac{69}{100}\\=0.69\\\\\mathrm{Multiply\:}0.69\mathrm{\:by\:}102.16\\\\=0.69\times\:102.16\\\\=70.4904\\\\=70[/tex]

Answer:89

Step-by-step explanation:

the equation is a^2+ B^2= c^2

8^2+ 5^2= X^2

64+25= X^2

89= X^2

The value of x is 9.4 units in the given right triangle, which is determined by   Pythagoras's theorem.

Pythagoras's theorem states that in a right-angled triangle, the square of one side is equal to the sum of the squares of the other two sides.

The triangle is given in the form of a right-angled triangle

According to Pythagoras's theorem,

The formula is a² + b² = c²

Here a = 8, b = 5, and c = x

Substitute the values in the above formula,

⇒ 8² + 5² =  x²

⇒ 64 + 25 = x²

⇒ 89 = x²

⇒ x² = 89

⇒ x = √89

⇒ x = 9.433

Rounded nearest tenth

⇒ x = 9.4

Therefore, the value of x is 9.4 units in the given right triangle.
