Answer:

5/8 yards

Step-by-step explanation:

Amount Used: 3/8 yard

Amount Remaining : 1/4

Amount started with  = Amount Used + Amount Remaining

We need to find the common denominator for 8 and 4.

3/8 stays 3/8, and 1/4 becomes 2/8    (multiply the numerator and                      

                                                                denominator of 1/4 by 2)

3/8 + 2/8 = 5/8

3/8 of the spool is used to make a bow.

She has 1/4 left. 1/4 = 2/8.

2/8 + 3/8 = 5/8

Answer:

∠ 2 = 26°

Step-by-step explanation:

Since EP is an angle bisector then ∠ 1 = ∠ 2

∠ 2 = [tex]\frac{1}{2}[/tex] ∠ GEF = [tex]\frac{1}{2}[/tex] × 52° = 26°

Answer:

$7.08

Step-by-step explanation:

59 cents = 1 sq ft

? = 12 sq ft

To get from the 1 to the 12 we multiply by 12, so we must do the same to the 59 cents.

0.59 * 12 = 7.08

Therefore, the cost of 12 sq ft is $7.08.

Answer:

24 hours

Step-by-step explanation:

If 12 workers take 10 hours to build a wall, assuming they build at the same rate, it would take one worker 120 hours to build a wall.

By this logic, it would take 120/5 or 24 hours for 5 workers to build a wall

The number of hours 5 men take with the same rate of 12 workers taking 10 hours will be 24 hours.

The rate of change is the change of a quantity over 1 unit of another quantity.

Most of the time the rate of change is the change with respect to time.

For example the speed 3meter/second.

The number of hours 1 person take to build the wall = 12 x 10 = 120 hour

Number of men = 5

The number of 5 men will take as 120/5 = 24 hour

Hence "The number of hours 5 men take with the same rate of 12 workers taking 10 hours will be 24 hours".

Answer:

$172.27

Step-by-step explanation:

Original: x

New: 205

Percent Increase : 19%

205 = 119% of x

205/119 * 100 = 20500/119 = 172.26890... ≈ 172.27

Sorry that this is long, but hopefully this has the answers and explanations you are looking for. Have a nice day!

1a: P' (0, 1) Q' (9, 7)

First, we will look at point P. It is at (-7, -2). If we move it up three and right 7, we will do (-7 +7, -2 +3) which gives us (0, 1). We do the same for Q, (2, 4) -> (2+7, 4 +3) = (9, 7)

2a: This transformation represents the point being moved down 5 units and to the right 2 units. X is left/right and it's being moved positive two, hence right 2. Y is up/down, and it's being moved negative 5, hence down 5.

2b: (4, -3) (not 100% sure on this one)

The wording slightly confused me, but if it's talking about having point A be apart of 2a, here is what we do:

(2, 2) -> (2 + 2, 2 - 5) -> (4, -3)

3a: (x - 26, y + 17)

So (in the y) -13 becomes 4, so it moves 17 units up. For the x, -2 becomes -28, so it is moved 26 units down. This becomes x - 26 and y + 17, which is written correctly above.

3b: A. AP and A'P' have different locations

For a translation shape, size, and direction doesn't change, just where it's at (location).

Answer:

Since you're looking for how many acres can be planted per pound of seed, you'd have to divide 9 by 80.

Once divided, you would get 0.1125.

Step-by-step explanation:

slope of AB = y2 -y1/x2 -x1 =14 -(-2)/1-9

= 14 +2 /1 -9

= 16/-8

= -2

slope of CD = -14 -(-10)/8 -6 = -14 +10 /2

-4/2 = -2

since slope of AB = CD

Answer:

Check picture

Step-by-step explanation:

Part A: The expression for the total number of minutes Mario volunteers each year at the animal shelter  =  (405/y)   x  365

Part B: The simplified form of the expression for the total number of minutes Mario volunteers each year at the animal shelter = (147825/y) minutes

Number of days Mario volunteers each month at the animal shelter = 1

Number of hours Mario cleans for y days = 5.5 hours

Number of hours Mario each day = 5.5/y

Number of minutes Mario uses to walk dogs for y days = 75 minutes

Number of hours Mario uses to walk dogs for y days=  75/60

Number of hours Mario uses to walk dogs for y days=  1.25 hours

Number of hours Mario uses to walk dogs each day= 1.25/y

Total number of hours Mario volunteers in a day = Number of hours Mario cleans each day + Number of hours Mario uses to walk dogs

Total number of hours Mario volunteers in a day = 5.5/y + 1.25/y

Total number of hours Mario volunteers in a day = 6.75/y

Convert the number of hours to minutes

1 hour   =  60 minutes

Total number of minutes Mario volunteers in a day = (6.75/y) x 60

Total number of minutes Mario volunteers in a day = (405/y) minutes

Number of days in 1 year = 365

The expression for the total number of minutes Mario volunteers each year at the animal shelter  =  (405/y)   x  365

The simplified form of the expression for the total number of minutes Mario volunteers each year at the animal shelter = (147825/y) minutes

Answer:

a = 3

b = 2

Step-by-step explanation:

Solve 4a - b = 10 for b:

Substitute 4a - 10 for b in 2a + 3b = 12

Substitute 3 for a in b = 4a - 10

Therefore, a = 3 and b = 2.

Answer:

Step-by-step explanation:

The standard form equation of a straight line is y=mx+b, where m is the slope and b is the y-intercept (the value of y when x=0). Rearrange each equation into this format.

1. 3x + 2y = 5

2y = -3x+5

y = -(3/2)x+(5/2)

a. I'll pick 2 values of x to find 2 values of y:

x y

2 -0.5

5 -5

b. The slope is -(3/2)

c. The y-intercept is (5/2)

2. 3y - x = 9

y = (1/3)x + 3

a. Pick 2 values of x to calculate y:

x y

2 3.67

5 4.67

b. The slope is (1/3)

c. The y-intercept is +3

The number of days passed to have an accumulated heartbeat of 504,000 is the ratio of the total heartbeat and the number of beat per minute ; Hence, the number of days is 5 days

Number of heartbeats per day = 70 × (24 × 60) = 100,800 beats

Number of days = (504,000) ÷ (100,800) = 5days

Therefore, the Number of days elapsed is 5 days.

Step-by-step explanation:

Answer:

x = 5/2cm

Step-by-step explanation:

Because this is a square and each side is equal to each other in length, we can say:

7x + 3 = 5x + 8

We can start rearranging this equation to collect like terms:

7x = 5x + 8 - 3

7x = 5x + 5

7x - 5x = 5

2x = 5

x = 5/2

We can test this out by substituting our new found value for x into the original equation:

7 * (5/2) + 3 = 5 * (5/2) + 8

(35/2) + 3 = (25/2) + 8

I'm going to change the integers (3 and 8) to fractions so the arithmetic is easier, as they'll all have the same denominator.

(35/2) + (6/2) = (25/2) + (16/2)

(41/2) = (41/2)

So as you can see above, with x = 5/2, both sides are equal.

You don't need to put the fractions in brackets; I just do that to make it look a little less messy.

Also, I've only included the units (cm) in the answer. I don't like using units when doing calculations, but your teacher may ask you to perform the calculations using the units throughout.
