A building contractor has a piece of crown molding that is 48 ½ inches long. He cuts off one piece measuring 10 ¼ inches and another piece 2 feet ⅛ inch.How much crown molding does he have left?

Answers

Answer 1

Answer:

14 1/8 inches of molding

Step-by-step explanation:

In order to find the solution, we'll have to do 2 fractions subtractions.

To be able to subtract fractions, we have to make sure they are placed in the same denominator.  So, the first thing we'll do is to convert all the numbers in 8th, because that's the greatest denominator.

[tex]48 \frac{1}{2}  = 48 \frac{4}{8} = \frac{(48 * 8) + 4}{8}  = \frac{388}{8}[/tex]

[tex]10 \frac{1}{4} = 10 \frac{2}{8} = \frac{(10 * 8) + 2}{8} = \frac{82}{8}[/tex]

For the last one, we'll first convert the 2 feet into 24 inches.

[tex]24 \frac{1}{8} = \frac{(24 * 8) + 1}{8} = \frac{193}{8}[/tex]

Now, we'll subtract each of the two pieces cut from the original molding's length, first the 10 1/4 inches piece

[tex]\frac{388}{8} - \frac{82}{8} = \frac{388 - 82}{8} = \frac{306}{8}[/tex]

then the 2 feet 1/8 piece

[tex]\frac{306}{8} -  \frac{193}{8} = \frac{306 - 193}{8} = \frac{113}{8} = 14 \frac{1}{8}[/tex]

So,  the contractor is left with 14 1/8 inches of molding.

2(x^2 -4x-45)

What two numbers multiply to -45 and add to -4

-9*5 = -45

-9+5 = -5

2(x-9) (x+5)

Set this equal to zero

2(x-9) (x+5) =0

Divide by 2

(x-9) (x+5) =0

Using the zero product property

The area of a playground is 160 yd2. The width of the playground is 6 yd longer than its length. Find the length and width of the playground.

Answers

Answer:

length=10\ yd,  width=16\ yd

Answer:

Length of the playground is 10 yd and the Width of the playground is 16 yd .

Step-by-step explanation:

Formula

Area of a rectangle = Length × Width

As given

The area of a playground is 160 yd².

The width of the playground is 6 yd longer than its length.

Let us assume that the length be x .

Thus

Width = x + 6

Put all the values in the formula

160 = x × (x + 6)

160 = x² + 6x

x² + 6x - 160 = 0

x² + 16x - 10x - 160 = 0

x (x + 16)-10 (x + 16) = 0

(x -10)(x + 16) = 0

Thus

Either (x - 10) = 0 or (x + 16 ) = 0

x = 10 or x = -16

(Negative value is neglected because sides cannot be negative.)

Thus

x = 10

Length = 10 yd

Width = 10 + 6

             = 16 yd

Therefore the length of the playground is 10 yd and the width of the playground is 16 yd .

The length of a rectangle is 6m more then the width. The area is 40m^2 . What is the length and the width?

Answers

let the width of the rectangle be x

area of rectangle is l*b

x * (x + 6) = 40^2

x^2 + 6x = 40^2

x^2 + 6x = 1600

x + 6x =√1600

x + 6x = 40

7x = 40

x = 5.7

Mary and Jane are trying to set up their marmalade selling business. They started off by peeling the oranges. Mary peels 8 oranges in 10 minutes while Jane peels 3 oranges in 5 minutes. If they need to peel 500 oranges for their first batch of marmalade, how long (in hours) will it take them to finish peeling? (round off to nearest hr)

Answers

Answer:

6.0 hours

Step-by-step explanation:

1 hour is the same as 60 minutes.

"Mary peels 8 oranges in 10 minutes"

1 hour = 60 minutes = 6 * 10 minutes

In 1 hour, she peels 6 times as many oranges, so Mary peels 48 oranges in 1 hour.

"Jane peels 3 oranges in 5 minutes"

1 hour = 60 minutes = 12 * 5 minutes

In 1 hour, she peels 12 times as many oranges, so Jane peels 36 oranges in 1 hour.

Combined, the peel 48 + 36 = 84 oranges in 1 hour.

(500 oranges)/(84 oranges/hour) = 5.952 hours

Answer: 6.0 hours

Answers

Answer:

not a factor

Step-by-step explanation:

If (x - 3) is a factor then f(3) = 0

f(x) = 2x² - 4x + 30

f(3) = 2(3)² - 4(3) + 30 = 18 - 12 + 30 = 36 ≠ 0

Since f(3) ≠ 0 then (x - 3) is not a factor of f(x)

Write the equation 4x + 2y = 5 in the form y = mx + b.

Answers

Answer:

4x+2y-5=0

Step-by-step explanation:

since you have to put the problem in that order you take 5 from both sides

Answer:

The correct answer is y = -2x + 5/2

Step-by-step explanation:

y = mx + b.  is the y intercept form of a line.

To find the  y = mx + b. form

It is given that,

4x + 2y = 5

2y = -4x + 5

Dividing both sides by 2 we get,

2y/2 = (-4x + 5)/2

y = -4x/2 + 5/2

y = -2x + 5/2

Here m = -2 and b = 5/2

Chris spent $8 on lunch. 75% was spent on a sub ad the rest was used to buy two cookies. How much was each cookie?

Answers

Answer:

1 dollar.

Step-by-step explanation:

"Chris spent $8 on lunch. 75% was spent on a sub ad the rest was used to buy two cookies. How much was each cookie?"

.75=75%

8*.75=cost of sub=6

total cost- cost of sub=cost of cookies

8-6=2

The cost of 2 cookies is 2 dollars

Now to find the cost per cookie we take the total cost of the cookies, and divide it by the amount of cookies-

2/2=cost per cookie=1

It cost $1 for each cookie.

Final answer is m∠D  = 61°.

Step-by-step explanation:

Given that m∠C = 98°,

m∠B = 140°,

m∠A = m∠D ,

Using those information we need to find the value of m∠D.

We know that sum of all 4 interior angles of a quadrilateral is always 360°.

So we can write equation:

m∠A +m∠B +m∠C +m∠D = 360°

m∠A + 140° + 98° +m∠D = 360°

m∠D + 140° + 98° +m∠D = 360°

2(m∠D) + 140° + 98° = 360°

2(m∠D) + 238° = 360°

2(m∠D)  = 360° - 238°

2(m∠D)  = 122°

m∠D  = 122°/2

m∠D  = 61°

Hene final answer is m∠D  = 61°.

Answer:

the answer is 61°

Step-by-step explanation:

360- 98- 140 = 122 ÷2 = 61

Step-by-step explanation:

we are given the angles of XYR = 40, ZXY = 130, and SRY = 40 degrees.

angle ZXY is half of angle ZAY, so angle ZXY is 65 degrees.

imagine a line XA (not on the diagram). then ZXA is 32.5 degrees since it is half of YXZ. Angle XZA and ZXA are equal, so XZA is 32.5 degrees. RZA = XZA + RZX = 32.5 + 40 degrees (assuming the upper left stated degree belongs to angle XZA), or simply RZA is 72.5 degrees.

since ZRA = RZA, then ZRA is 72.5 degrees. since angle ZRS = SRY + ZRA, finally ZRA = 40 + 72.5 degrees or simply, ZRS = 112.5 degrees. which visually is blantantly wrong as it appears to be less than 90 degrees.

When point A( 3, 1) is translated 2 units to the right and 6 units up the coordinates of point A'

Answers

Answer:

A' = (5,7)

Step-by-step explanation:

So, we start with the original point A at (3,1), that means x = 3 and y = 1.

We move it 2 units to the right... so we're moving along the X-axis... and we're moving to the right.. so we're increasing the value of x.  That means starting with x = 3, we go 2 more units... we then get to x = 5.

In the same way, we move 6 units up... so we move along the Y-axis.  We go up, so we also increase the value of y.  Starting with y = 1, we move up by 6 units... so we are now at y = 7.

A' point is then at (5,7).
