Answer:

Step-by-step explanation:

let x be the length of one base in mm

The other base will be 2x - 7 mm

I will ASSUME you mean the area is 48 mm²

Area of a trapezoid is the Average base length times height

A = ½(x + (2x - 7))h

A = ½(3x - 7)h

2A/h = 3x - 7

2A/h + 7 = 3x

x = (2A/h + 7)/3

x = 2A/3h + 7/3

x = 2(48)/3(12) + 7/3

x = 5 mm

the other length is

2(5) - 7 = 3 mm

Answer:

Step-by-step explanation:

We translate Grayson's charges through the following mathematical expression : 35 h + 35 where h is the number of hours while that of Ian is 45h + 15. The number of hours where the charges are equal is 35h + 35 = 45h + 15; h = 2 hrs. Hence the number of hours minimum must be above 2 hours.

Answer:

of angle J in degrees = 59 degree

Step-by-step explanation:

x+17 + 4x-3 + 2x+5 =180 degree

7x+19 = 180 degree

7x = 180-19

x = 161/7

x= 27

so angle J in degree ,

(2x+5) degree

(2×27)+5

59 degree

Answer:

8500m

Step-by-step explanation:

t = 15 + 0.01 h

t = 100 (given in the question)

∴ 100 = 15 + 0.01 h

   100 - 15 = 0.01 h

   85 = 0.01 h

   85 / 0.01 = h

   8500 / 1 = h

  8500 = h

Answer:

3,000

Step-by-step explanation:

New value =

2,400 + Percentage increase =

2,400 + (25% × 2,400) =

2,400 + 25% × 2,400 =

(1 + 25%) × 2,400 =

(100% + 25%) × 2,400 =

125% × 2,400 =

125 ÷ 100 × 2,400 =

125 × 2,400 ÷ 100 =

300,000 ÷ 100 =

3,000

Answer: Area = 234

Step-by-step explanation:

Area for rectangle is length(13) x width(18) == 234

Answer:

14

Step-by-step explanation:

This can be seen as a arithmetic series. It is the number of girls, let’s say g, plus the number of girls plus five boys. Deena, can be viewed as 1, plus 5 equals 6. Then Chloe, 2, plus 5 equals 7. And so on and on.

We can create an equation for this:

g+(g+5)=s

(s is the number of students.)

‘If the total number of students is 23;

g+(g+5)=23

We can solve this for:

2g = 23-5 ⇒

g=9

So the number of girls is 9, th number of boys is simply:

23-9=14

Does this help?

Step-by-step explanation:

The triangles would not be congruent since it was dilated.

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.

Rigid transformation are transformation that preserve the shape and size of the figure. These are rotation, reflection, and translation. Dilation is not a rigid transformation because it reduces or increases the size of the figure.

Two triangles are congruent if they have the same shape and size.

The triangles would not be congruent since it was dilated.

My understanding of rational numbers will be A. I can explain what rational and irrational numbers are, and I can identify them. I can use rational numbers to estimate the value of an irrational number.

It should be noted that rational numbers are the numbers that are expressed as the ratio of two integers.

It should be noted that they can be fractions, integers, decimals,etc. Examples include 5, 3.7, 1/5, etc.

A rational number is one that can be written as the ratio or fraction p/q of two numbers, where p and q are the numerator and denominator, respectively. For instance, every integer and 3/7 are rational numbers.

A real number that cannot be expressed as a straightforward fraction is referred to as an irrational number. It cannot be described using a ratio. When p and q are integers and q is not equal to 0, N is not equal to p/q if N is irrational.

Answer:

X = 9

Step-by-step explanation:

7x + 3x - 18= 6(x+3)

7x + 3x = 10x - 18 = 6(x+3)

10x - 18 = 6(x+3) convert that into (distribute) 6x + 18

                                                                            +18  +18 (add 18 to both sides)

Simplify:  10x +  6x + 36 (subtract 6x form both sides)

                        -6       -6

Simplify: 4x = 36 (divide each by 4)

Answer:

12 apples

Step-by-step explanation:

5 apples = 0.6kg

1 apple = 0.12kg

x = 0.6kg x 2

= 1.2kg (10 apples)

y = 1.44kg - 1.2kg

= 0.24kg (2 apples)

Apples = x + y

= 10 + 2 apples

= 12 apples (weigh 1.44kg)

Answer:

Circumference ≈ 82.9

Step-by-step explanation:

The formula for calculating the circumference of a circle is:

C = 2πr

Where 3.14 is pi (as stated on your screen)

And r is the radius.

Knowing this substitute those values

C = 2(3.14)(13.2)

Multiply 2 and 3.14.

C = (6.28)(13.2)

Multiply 6.28 and 13.2.

C = 82.9 when rounded.

Answer:

x²-6x+y²-4y=-4

Step-by-step explanation:

We know the circle equation stands like this:

(x-a)² + (y-b)² = R²

and (a,b) is center

and R stands for Radius

so in this case:

center = (3,2)

R = 3

So

(x-3)² + (y-2)² = 9

x²-6x+9 + y²-4y+4=9

x²-6x+y²-4y=-4
