Answer:

Scale 1 35 ft by 25 ft and Scale 2 56 ft by 40 ft

Step-by-step explanation:

step 1

Find the actual dimensions of a patio with the scale 1

The scale 1 is equal to

1 cm/5 ft

Length=7 cm=7*5=35 ft

Width=5 cm=5*5=25 ft

therefore

The dimensions are 35 ft by 25 ft

step 2

Find the actual dimensions of a patio with the scale 2

The scale 2 is equal to

1 cm/8 ft

Length=7 cm=7*8=56 ft

Width=5 cm=5*8=40 ft

therefore

The dimensions are 56 ft by 40 ft

70 POINTS! PLEASE HELP! Explain the difference between the following equation formats: Slope-Intercept, Point-Slope and Standard

katrin2010 [14]

Answer and Step-by-step explanation:

1. slope intercept

2. point-slope form

3. standard

Explanation:

1. A slope intercept form equation is when it's set up as y = m x + b

m = slope

b = y-intercept

2. A point-slope form is when a line passes through a point

and the equation is set up as y −b = m ( x−a)

m = slope

(a, b) A point that the line passes through

3. standard lope form is when the equation is set up as

Ax + By = C

Which inequality correctly compares Two-fifths, Six-sevenths, Five-eighths, and 1?

Ronch [10]

Answer:

2/5 < 5/8 < 6/7 < 1

OR

1 > 6/7 > 5/8 > 2/5

Step-by-step explanation:

It is required to compare Two-fifths, Six-sevenths, Five-eighths, and 1

Two-fifths = 2/5

Six-sevenths = 6/7

Five-eighths = 5/8

So, the given numbers are: 2/5, 6/7, 5/8, and 1

We need to make the numbers in order from the least to the greatest or from the greatest to the least

The easy method is convert the rational numbers to decimal numbers

So,

2/5 = 0.4

6/7 ≈ 0.857

5/8 = 0.625

1 = 1

So, the numbers form the least to the greatest are:

0.4 , 0.625 , 0.857 , 1

So,

2/5 , 5/8 , 6/7 , 1

The inequality correctly compares the numbers are:

2/5 < 5/8 < 6/7 < 1

Or can be written from the greatest to the least as:

1 > 6/7 > 5/8 > 2/5

Simplify: -c - 8(4c - 5) - (-18c + 3)

d1i1m1o1n [39]

Answer:

-15c + 2

Step-by-step explanation:

you start by multiplying the coefficients of the parentheses to the numbers inside which gives you

- c - 32c + 5 + 18c - 3

then you simply just group together the like numbers. all "c" 's go together and everything without a "c" goes together

- 1c - 32c + 18c= -15c

5 - 3 = 2

the final answer simplified is

-15c + 2

10. JKLM is a rhombus KLN is a triangle. Find MKN.

rjkz [21]

Answer:

65°

Step-by-step explanation:

JM = JK (all sides of a rhombus are equal)

Angle JKM = 25° (isosceles triangle)

Angle JKL = 50° (consecutive angles of rhombus)

Angle MKL = 25° (angle subtraction)

Angle MLK = 130° (opposite angles of a rhombus)

Angle KLN = 50° (angles on a straight line)

Angle LKN = 40° (angle sum of triangle)

Angle MKN = 65° (angle addition)

21) 7/16

22) 2/60

23) 3/8

24) 35/63 or 5/9

25) 7/32

26) 45/60 or 9/12 or 3/4

27) 1/32

28) 3/21 or 1/7

29) 13/6 × 9/2

= 117/12

30) 3/4 × 17/2

= 51/8

31) 9/8 × 10/3

= 90/24

= 45/12

= 15/4

32) 16/5 × 2/3

= 32/15
