Step-by-step explanation:You can get this by multiplying what ever number you want, as long as you do the same for the other number. Example, 2/3= 10/15, I just multiplied both sides with the same number.

Answer:

  a) 1/48

  b) 36/1

Step-by-step explanation:

The scale factor from 2nd to 1st is the ratio of the scale factors.

(a) (1/280)/(6/35) = (1/280)(35/6) = 35/(35·8·6) = 1/48

__

(b) (3)/(1/12) = 3·12/1 = 36/1

Area of triangle = 1/2 x base x height:

Area of triangle = 1/2 x 14 x 5 = 35

Area of square = 2 x 2 = 4

Shaded area = 35-4 = 31 cm^2

Answer:

Step-by-step explanation:

Let the wallpaper be a rectangle

Area of a rectangle = Length * Width

A = LW

Perimeter P = 2L+2W

If the wallpaper is sold in rolls that are 2 feet wide, then the width is 2 feet, to get the length, substitute W = 2 and P = 60 into the formula for calculating the perimeter of a rectangle.

60 = 2L + 2(2)

60 = 2L + 4

2L = 60-4

2L = 56

L = 56/2

L = 28

The minimum length that will be purchased to cover the wall is 28 feet

Answer:

$431.67

Step-by-step explanation:

Let

The one time $50 rebate be for the first month

Cost of insurance per month = x

First month cost of insurance = x-50

Total cost of insurance = $2,540

Total cost of insurance = 1st + 2nd + 3rd + 4th + 5th + 6th

2,540 = x-50 + x + x + x + x + x

2540 + 50 = 6x

2590 = 6x

Divide both sides by 6

x= 2,590 / 6

= 431.67

x= $431,67

The cost of the insurance per month = $431.67

Check:

$431.67 * 6 months

=$2,590.02

Minus one time rebate of $50

= $2,590.02 - $50

= $2,540.02

Approximately

$2,540

I'm not good in this but.....

x = years

Answer:the bicycle function has the greater slope, which shows that the cost per hour is greater than that of the in-line skates

Step-by-step explanation:

The function has the greater slope and it represent : The bicycle function has the greater slope, which shows that the cost per hour is greater than that of the in-line skates

Linear functions are those whose graph is a straight line. A linear function has the following form. y = f(x) = a + bx. A linear function has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y.

The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).

According to the question

The cost per hour to rent a bicycle and the cost per hour to rent in-line skates are given .

We will conclude which function has the greater slopes

if any function have greater slope than other that implies that  it have greater change in  y  axis in comparison to other

as over here  

y axis = cost

x axis = hours

Therefore,

The bicycle function has the greater slope, which shows that the cost per hour is greater than that of the in-line skates

Hence, The bicycle function has the greater slope, which shows that the cost per hour is greater than that of the in-line skates

Answer:

2x+8y

Step-by-step explanation:

Answer: 8x^2 - 15^2 + xy

Step-by-step explanation:

expand brackets by multiplying

(4x+5y)(2x-3y)+3xy

8x^2 - 12xy + 10xy - 15y^2 + 3xy

collect like terms

8x^2 - 15y^2 -12xy + 10xy + 3xy

solve

-12xy + 10xy + 3xy

=1xy (note: when writing/typing the answer, don't add 1 in front of the xy.)

final answer: 8x^2 - 15y^2 + xy

Answer:

the moon is 15,840,000,000 inches away

Step-by-step explanation:

The distance of the moon from the earth in inches is 1583926.56 ×10⁴ inches.

The unitary method is a method in which you find the value of a unit and then the value of a required number of units.

Given here, The moon is 250,000 miles away. How many inches and

we know that 1 mile =63357.0626 miles

Thus 250000 mile = 1583926.56 ×10⁴

Hence, The distance of the moon from the earth in inches is 1583926.56 ×10⁴ inches.

Answer:

2x(3x+5)+1(3x+5)

Step-by-step explanation:

The distributive law is the law that states that multiplying a number by a group of numbers is the same as doing each multiplication separately. Eg. A(B+C) =AB+AC

In the case of two sets of parenthesis it would look like:

2x(3x+5)+1(3x+5)

Which would give us:

6x^2 +10x +3x+5

6x^2+13x+5

The general format for 2 bracket ones would be:

(A+B) (C+D) =A(C+D) +B(C+D)

where the two terms in the first bracket go outside the second bracket twice individually because each term must be multiplied by all terms in the other bracket.

Answer:

The numerical length of SU =

5 units

Step-by-step explanation:

Here, we want to get the length of point SU

mathematically;

SU = ST + TU

4x + 1 = 3x -1 + 3x

4x + 1 = 6x - 1

6x-4x = 1 + 1

2x = 2

x =2/2 = 1

But SU = 4x + 1 = 4(1) + 1 = 5 units

To find the mean,add everything up, the divide it by how many numbers you added up.

So, do :

3 + 2 + 2 + 12 + 6 + 5 + 14 + 4 = 48

Then, because you added 8 numbers together, you would divide 8 from 48.

48 ÷ 8 = 6

So, your mean is  6
