Answer:

42.5 square units

Step-by-step explanation:

To solve, we can split this shape up into 4 known shapes:

2 unit by 2 unit triangle

2 unit by 2 unit square

2 unit by 5 unit triangle

3.5 unit by 9.0 unit rectangle

Now let's solve these areas:

2 x 2 = 4 / 2 = 2

2 x 2 = 4

2 x 5 = 10 / 2 = 5

3.5 x 9.0 = 31.5

Then add all these values together:

2 + 4 + 5 + 31.5 = 42.5

Answer: 4/10 = 2/5

2/8 = 1/4

3/5 = 3/5

4/12 = 1/3

6/10 = 3/5

3/6 = 1/2

Step-by-step explanation:

4/10 = 2/5

4/10 is not in its simplest form.

Both 4 and 10 can be divided by 2.

Therefore, 4/10 = 2/5

2/8 = 1/4

2/8 is not in its simplest form

2 / 2 = 1

8 / 2 = 4

Both 2 and 8 can be divided by 2, therefore, 2/8 = 1/4

3/5 = 3/5

3/5 is in its simplest form

3 and 5 are prime, so they don’t have any factors other than 1 and itself so they wouldn’t be able to be simplified.

4/12 = 1/3

4/12 is not in its simplest form

4 / 4 = 1

12 / 4 = 3

4 and 12 can be divided by 4, resulting in 1 and 3. Therefore, 4/12 = 1/3.

6/10 = 3/5

6/10 is not in its simplest form

6 / 2 = 3

10 / 2 = 5

6 and 10 can both be divided by 2, resulting in 3/5. Therefore, 6/10 = 3/5

3/6 = 1/2

3/6 is not in its simplest form

3 / 3 = 1

6 / 3 = 2

Both 3 and 6 can be divided by 3, resulting in 1/2

Therefore, 3/6 = 1/2

Short Answers:

4/10 = 2/5

2/8 = 1/4

3/5 = 3/5

4/12 = 1/3

6/10 = 3/5

3/6 = 1/2

======================================================

Work Shown:

x = number of light bulbs

3.40x = total cost to buy x light bulbs, cost is in pounds

3.40x = 30

x = 30/(3.40)

x = 8.823529 approximately

Rounding down, we get 8

Note that,

Therefore, the highest number of bulbs that can be bought is 8.

The change given will be 30-27.20 = 2.80 pounds

Answer:

a)   t-4 = 3 (i - 1/4h) =  h = 3i - 3 3/4h  

= t = -0.75

= h = 4  

b) 3.30am = 1 inch.

Step-by-step explanation:

a)   formula for point slope form = y - y1 = m(x-x1)

a) t-4 = 3(i - 1/4h)  converts to  t-4   = 3i - 3/4h  = t = 3i- 3 3/4

x = - 0.75 y = 4  =     t= -0.75 and h = 4

b) 12.15am = 4 inches

1.15am = 3.25 inches

2.15am = 2.5 inches

3.15am = 1.75inches

3.30 = 1 inches

3.15 + 15mins = 1 inch

Answer:

$557.52

Step-by-step explanation:

1. Find the marked up price.

125% = 1.25

$892.03 x 1.25 = $1,115.04

2. Find the discounted price.

50% = 0.5

$1,115.04 x 0.5 = $557.52

Answer:

The ratio is 3:1

Step-by-step explanation:

[tex]\frac{10 yards}{10 feet}[/tex]

We know, 1 yard is equal to 3 feet

So, [tex]\frac{10 yards X 3}{10 feet}[/tex] is equal to [tex]\frac{30 feet}{10 feet}[/tex] is equal to 3:1

Answer:

in the -1,-1

Step-by-step explanation:

Step-by-step explanation:

Line segment = EG

point on a line segment = F

EG = 100

EF = 4x - 20

FG = 2x + 30

a/q, EF + FG = EG

the equation is

4x - 20 + 2x + 30 = 100

now solution for x is

→ 4x - 20 + 2x + 30 = 100

→ 6x + 10 = 100

→ 6x = 100 - 10 = 90

→ x = 90/6 = 15

therefore, value of x is 15.

and according to given information

EF = 4x - 20 = 4(15) - 20 = 60 - 20 = 40

FG = 2x + 30 = 2(15) + 30 = 30 + 30 = 60

hope this answer helps you dear..take care and may u have a great day ahead!

Answer:

y=-1/2x-9/2

Step-by-step explanation:

check picture

The equation of the line perpendicular to y = 2x - 3 that passes through the point (-3, -3) is y = (-1/2)x - 9/2 in slope-intercept form.

To find the equation of a line perpendicular to y = 2x - 3, we need to determine the slope of the original line and then find the negative reciprocal of that slope.

The original line has a slope of 2. The negative reciprocal of 2 is -1/2.

Now, we have the slope (-1/2) and the point (-3, -3) that the perpendicular line passes through.

We can use the point-slope form of a linear equation to write the equation of the line:

y - y1 = m(x - x1)

Substituting the values:

y - (-3) = (-1/2)(x - (-3))

y + 3 = (-1/2)(x + 3)

Expanding and simplifying:

y + 3 = (-1/2)x - 3/2

y = (-1/2)x - 3/2 - 3

y = (-1/2)x - 3/2 - 6/2

y = (-1/2)x - 9/2

Therefore, the equation of the line perpendicular to y = 2x - 3 that passes through the point (-3, -3) is y = (-1/2)x - 9/2 in slope-intercept form.

Step-by-step explanation:

Answer:

18.75.

Step-by-step explanation:

If he already owes his mother 12.25 and borrows 6.50, we can add those numbers up to get the total amount of how much he owes his mother.

12.25 + 6.50 = 18.75

Therefore, Joseph's debt to his mother can be represented using the equation above.

Answer:

y= 5x+20

Step-by-step explanation:

Slope intercept form is

y = mx+b where m is the slope and b is the y intercept

The slope is 5 and a point on the line is (-4,0)

Substituting this information into the equation, we can solve for b

0 = 5(-4) +b

0 = -20+b

Add 20 to each side

0+20 = -20+20+b

20 = b

y = 5x+20

Step-by-step explanation:

Answer:

( - 6, 1.5 )

Step-by-step explanation:

( x1, y1 ) = ( - 2, - 1 )

Here,

x1 = - 2

y1 = - 1

( x2, y2 ) = ( - 10, 4 )

Here,

x2 = - 10

y2 = 4

Formula : -

Mid - point = ( x1 + x2 ) / 2, ( y1 + y2 ) / 2

Mid - point = ( - 2 - 10 ) / 2, ( - 1 + 4 ) / 2

                  = - 12 / 2, 3 / 2

Mid - point = ( - 6, 1.5 )
