Answer:

6.2

Step-by-step explanation:

Okay so in order to solve this equation you are going to have to round up the tenths place which is the space after the decimal point.

6.16 = 6.2

because 6 is above 5 you are able to round up to ten turning 6.16 to 6.2

Hope this helps you!!!

Hi there! Your answer is A, B, and C.

Step-by-step explanation:

It has four sides and whatever shape has four sides is a quad. We can also see that it equal sides so it can be both a square and a rhombus. Remember that a rhombus can be both a square and a rhombus.

Answer: (-1/3, 3/5)

Step-by-step explanation:

Solve for the first variable in one of the equations, then substitute the result into the other equation.

Point Form:

(−1/3,3/5)

Equation Form:

x=−1/3, y=3/5

Answer:

Area of a trapezium = 1/2 * sum of parallel sides * distance between them

= 1/2 * (10 + 18) * 6

= 1/2 * 28 * 6

= 84 feet ^2

Area of a rectangle = length * breadth

= 18 * 12

= 216 feet ^2

Total Area = 84 + 216

Total area = 300 feet

Answer: The position of -24 is to the left of -14.

The position of -14 is to the right of -24.

Step-by-step explanation:

We can conclude that -18 < -2.

We can conclude that -14> -24.

Answer:

i)  (x -y) -y  = 11

ii) (x+y) + x² = 8

iii) The two pairs (( 3 , -4)) and ( ( 3 ,4) satisfy the equation   x² + y² = 25

Step-by-step explanation:

Step(i):-

Given that x =3 and y=-4

i)  (x -y) -y = (3-(-4))-(-4) = 3+4+4 = 11

ii) (x+y) + x² = ( 3 -4) + (3)² = -1 + 9 = 8

Step(ii):-

Given equation  

                    x² + y² = 25

we can choose (x,y) = ( 3 , -4)

                 3²+(-4)² = 25

                     25    = 25

The ordered pair ( 3,-4) satisfies the equation

second ordered pair ( 3 ,4)

                        x² + y² = 25

                       9 + 16 = 25

                           25 = 25

Final answer:-

i)  (x -y) -y  = 11

ii) (x+y) + x² = 8

iii) The two pairs (( 3 , -4)) and ( ( 3 ,4) satisfy the equation   x² + y² = 25

Answer:. The deposit is £600

Step-by-step explanation:

Multiply £20 times 48 to find the total of the monthly payments.

20 × 48 =£960

Subtract that from the initial cost to find the deposit.

1560 - 960 = 600

Answer:

y=x^2-2

Step-by-step explanation:

Linear functions have a constant slope, so nonlinear functions have a slope that varies between points. Algebraically, linear functions are polynomials with highest exponent equal to 1 or of the form y = c where c is constant. Nonlinear functions are all other functions. An example of a nonlinear function is y = x^2

Answer:

y=x^2 -2

Step-by-step explanation:

This will result in a parabola, which does not fit the description of a linear function.

C. Integers, Whole, and Rational Numbers

Step-by-step explanation:

Since 16 is a whole number, it is also an integer and whole number.

Here is a little tip: Any number that is a whole number will also be an integer and a rational number.

Answer:

Mathematically speaking, both of these are what are called measures. They are ways of getting at the size of something.

The circumference of a circle is a line, which is one-dimensional, which means it has length but zero width. The area of a circle, in contrast, is two-dimensional. This is the essential difference.

The consequence of this is that circumference is measured in units like centrimetres, or inches, or miles. But area is measured in units like square-centimetres, square inches, or square miles.

Is this what you meant?

Answer:

the circumference is the distance around the circle so u can use the formula c=2πr

the radius formula is r=c/2π

the diameter formula is d=2r

Answer:

8.16

Step-by-step explanation:

8.16 divided by 0.8 = 10.2

The value of number will be 12.75.

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

We have to given that;

Number 10.2 divided by something equals 0.8.

Now,

Let the value of number = x

So, We can formulate;

⇒ 10.2 ÷ x = 0.8

Solve for x as;

⇒ 10.2 / x = 0.8

⇒ x = 10.2 / 0.8

⇒ x = 12.75

Thus, The value of number = 12.75
