Answer:

Ok so the answer is sqrt of 39 but think about

Step-by-step explanation:

sqrt81 is 9 which is a whole number it is rational

sqrt16 is 4 which again is a whole number and is rational

1.9 is rational because it can be written as a fraction or ratio

but sqrt39 is a repeating decimal that goes on forever it still is a real number not fitting into the imaginary category but not a ration number.

Answer: To determine to measure of the unknown angle, be sure to use the total sum of 180°. If two angles are given, add them together and then subtract from 180°. If two angles are the same and unknown, subtract the known angle from 180° and then divide by 2.

Step-by-step explanation:

Answer:

A. 6

Step-by-step explanation:

Since, cake is of right triangled shape, so measure of its one angle would be 90° and the sum of the measures of the remaining two angles will also be equal 90°.

Therefore,

5x +10x = 90

15x = 90

x = 90/15

x = 6

Answer:

13

Step-by-step explanation:

the top angle is 45°, and then there is the 90° angle, so the other angle must also be 45°. this makes it a right isosceles triangle, so both legs must be equal (they are both 13)

Answer:

The point C is 12.68 km away from the point A on a bearing of S23.23°W.

Step-by-step explanation:

Given that AB is 50 km and BC is 40 km as shown in the figure.

From the figure, the length of x-component of AC = |AB sin 80° - BC cos 20°|

=|50 sin 80° - 40 cos 20°|=11.65 km

The length of y-component of AC = |AB cos 80° - BC sin 20°|

=|50 cos 80° - 40 sin 20°|= 5 km

tan[tex]\theta[/tex]= 5/11.65

[tex]\theta[/tex]=23.23°

AC= [tex]\sqrt{5^2+11.65^2}=12.68[/tex] km

Hence, the point C is 12.68 km away from the point A on a bearing of S23.23°W.

Answer:

Area=42.25 square inches

if a cube, total area=253.5 square inches

Step-by-step explanation:

Area= (side)(side)

Area=6.5"x6.5"=42.25 in^2

if a cube (6 sides)

42.25X6=253.5in^2

Answer:

  t = 4°

Step-by-step explanation:

As in any triangle, the sum of angles is 180°.

  17t + 16t + 12t = 180°

  45t = 180° . . . . . collect terms

  t = (180/45)° . . . . divide by the coefficient of t

  t = 4°

Answer:

x=a+b/2

Step-by-step explanation:

1. adding a to both sides

2. dividing both sides by 2

2x-a=b

2x=a+b

x=a+b/2

Answer:How to Write 0.17 or 17% as a Fraction?

Decimal Fraction Percentage

0.2 20/100 20%

0.19 19/100 19%

0.18 18/100 18%

0.17 17/100 17%

Step-by-step explanation:

The percentage value ( 17 % ) as a fraction is A = 17/100

An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.

Given data ,

Let the percentage value be represented as A

Now , the value of A = 17 %

And , percent" means "per hundred".

So, 17% means 17 per hundred, or 17/100

Hence , the fraction is A = 17/100

Answer:

first one to the left, last one to the right

Step-by-step explanation:

Step-by-step explanation:

The x-intercept(s) of a quadratic function are equidistant from the vertex. (if any x-intercept exists)

The vertex has x-value 4. Since one of the x-intercepts is 1, the other must be 7.

(7 - 4 = 3, 4 - 1 = 3)
