Step-by-step explanation:

If they do it together in 6 minutes.

& Katy can do it in 18 minutes alone

Then 18 - x = 6

replace x for twelve

18 - twelve = 6

Ans: twelve

Answer:

No, it does not.

Step-by-step explanation:

This does not make a right triangle because in order to have a right triangle you must have 2 of the same numbers.

For example:

900, 800, 900 makes a right triangle

900, 800, 700 does not.

Answer:

154°

Step-by-step explanation:

They are alternate angles.

Answer:

154 degrees

Step-by-step explanation:

I'm going to use simple terms, you see there are two types of angles? One acute and the other obtuse. All the angles that are obtuse are the same and vis versa for acute angles too. It's just a rule for two parallel lines that are intersected by a perpendicular one.

Answer:

10 units

Step-by-step explanation:

You can create point c at (3,4) to make a right triangle

Then you know that the 2 legs are 6 and 8

We need to find the hypotenuse

You can use pythagorean theorem:

6^2+8^2=c^2

So c=10

So the distance is 10 units

Answer:

I think the answer is 19

Step-by-step explanation:

Answer:

Remember, the mean is calculated by adding the scores together and then dividing by the number of scores you added. In this case, the mean would be 2 + 4 (add the two middle numbers), which equals 6. Then, you take 6 and divide it by 2 (the total number of scores you added together), which equals 3.

Answer:

59

Step-by-step explanation:

Suppose a, b, c, d, e and f represent the 6 numbers.  

Then, [tex]\frac{a + b + c + d + e + f}{6} = 14\\[/tex]

(1)         a + b + c + d + e + f = 84

Let's remove f

then [tex]\frac{a + b + c + d + e}{5} = 5[/tex]

(2)        a + b + c + d +e = 25

Substitute 25 in for  a + b + c + d +e in equation (1)

We have 25 + f = 84

                       f  = 59

Answer:

2/5; 1/2; 2/3; 14/10; 2/6

Step-by-step explanation:

When finding equivalent fractions, multiply or divide both the numerator and denominator by the same number.

4/10 = 2/5 because 4÷2=2 and 10÷2=5

The same thing has been done to both the numerator and denominator (in this case they have both been divided by 2)

Answer:

148.12m²

Step-by-step explanation:

At first, lets find the area of rectangle.

length = 14m

breadth = 6m

Area of rectangle = length x breadth

= 14 x 6

= 84m²

Now, For the area of sector of the circle,

Given angle (a) = 34

radius = 14m

Area of the sector = a / 360 x pi x r²

= 34/360 x 3.14 x 14²

= 34 / 360 x 3.14 x 196

= 58.12m²

Now adding both areas,

84 + 58.12 = 142.12m²

Segment of a circle is the part of the circle. The total area of the composite figure is 142.1544 m².

The area of the segment of the circle is given by the formula,

[tex]\rm \text{Area of the rectangle} = \pi r^2 \times \dfrac{\theta}{360}[/tex]

As it is given that the composite figure is made up of a circular segment and a rectangle, therefore, we will find the area of the rectangle and the area of the circular segment individually.

Area of the rectangle

The area of the rectangle is the product of its length and breadth, therefore, the area is,

[tex]\rm \text{Area of the rectangle} = Length \times breadth[/tex]

                                [tex]= 14 \times 6\\\\=84\rm\ m^2[/tex]                

Area of the sector of the circle

[tex]\rm \text{Area of the rectangle} = \pi r^2 \times \dfrac{\theta}{360}[/tex]

                                   [tex]= \pi \times 14^2 \times \dfrac{34}{360}\\\\=58.1544\rm\ m^2[/tex]

The total area of the composite figure

The total area of the composite figure

= Area of rectangle + Area of the segment of the circle

= 84 + 58.1544 m²

= 142.1544 m²

Hence, the total area of the composite figure is 142.1544 m².

<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3

Answer:

Let's solve your equation step-by-step.

11x − 2x + 15 = 8 + 7 + 9x

Step 1:

Simplify both sides of the equation.

11x − 2x + 15 = 8 + 7 + 9x

11x + −2x + 15 = 8 + 7 + 9x

( 11x + −2x ) + ( 15 ) = ( 9x ) + ( 8 + 7 )

( Combine Like Terms )

9x + 15 = 9x + 15

9x + 15 = 9x + 15

Step 2:

Subtract 9x from both sides.

9x + 15 − 9x = 9x + 15 − 9x

15 = 15

Step 3:

Subtract 15 from both sides.

15 − 15 = 15 − 15

0 = 0
