By using division, if 89 members of the Taft school band spend a total of $4628 for tickets to Hammond's amusement park, The the cost of each amusement park ticket is $52

The total number of members of the Taft school = 89 members

The total cost for the ticket to Hammond's amusement park = $4628

The cost of each amusement park ticket = The total cost for the ticket to Hammond's amusement park ÷ The total number of members of the Taft school

Substitute the values in the equation

The cost of each amusement park ticket = 4628/89

= $52

Hence, by using division, if 89 members of the Taft school band spend a total of $4628 for tickets to Hammond's amusement park, The the cost of each amusement park ticket is $52

Lisa spent 90% of the total money on the fruits.

In mathematics, a percentage is a number or ratio expressed as a fraction of 100.

Given is Lisa spent $27 on fruits at the grocery store. She spent a total of $30 at the same store.

Money spent by Lisa on fruits = $27

Total money spent by Lisa = $30

Therefore, percentage of the total money she spend on fruits will be -

(27/30) x 100 = 90%

Hence, Lisa spent 90% of the total money on the fruits.

Provided the owner can bring 500 lbs of crabs to sell at the weekend seafood festival, they can earn between $4,250 and $5,250, depending on which type of crabs or their different combinations.

The total earnings can be determined using mathematical operations of multiplication, division, addition, and subtraction.

The total earnings are the products (multiplication results) of the units of each type of crab and their selling prices.

The selling price of Maryland crabs per Ib = $10.50

The selling price of Alaskan crabs per lb = $8.50

The total quantity of crabs the owner can bring to the seafood festival = 500 lbs

If the owner decides to bring in Maryland crabs, they can earn $5,250 ($10.50 x 500)

If the owner decides to bring in Alaskan crabs, they can earn $4,250 ($8.50 x 500)

If the owner decides to bring a combination of Maryland and Alaskan in the ratio of 50:50, they can earn $4,750 ($10.50 x 250) + $8.50 x 250)

Thus, if the owner sells Maryland crabs, the total earnings are $5,250, but if they sell Alaskan crabs, they earn $4,250.

Step-by-step explanation:

Answer:

y = (3/2)x + 3

Step-by-step explanation:

Comment

The general equation is

y = mx + b

Finding m

The equation for the slope is

m = (y2 - y1)/(x2 - x1)

Givens

y2 = 3

y1 = 0

x2 = 0

x1 = - 2

m = (3 - 0)/(0 - -2)

m = 3 / 2

m = 3/2

Finding b

b is the y intercept which is (0,3)

x = 0

y = 3

3 = 0*3 + b

b = 3

So the equation is

y = (3/2) x + 3

The machine will use 90 gallons of water to wash 24.5 pounds of laundry.

                     y ∝ x

Consequently, y = kx, where k is the proportionality constant.

Given:

The amount of water used by a washing machine varies directly with the weight of the load being washed.

Let's assume,

The amount of water used by a washing machine is y.

The weight of the load being washed is x.

According to the question,

y = 28 gallons

x = 7 pounds

Putting the values we get,

y = kx

28 = k × 7

k = 4

Now, we have to find y when x = 24.5

y = 4 × 24.5 = 98

Hence the machine will use 90 gallons of water to wash 24.5 pounds of laundry.

The new conditional statement that follows from the pair of true statement is If 4x + 5 = 13; then -5x = -10

The law of Syllogism states that if the following two statements are true:

Statement 1: If x , then y

Statement 2: If y , then z

Then we can derive a third true statement:

Statement 3: If x , then z

From the given;

Statement 1: If x , then y

If 4x + 5 = 13; then x = 2

Statement 2: If y , then z

If x = 2; then -5x = -10

Statement 3: If x , then z

If 4x + 5 = 13; then -5x = -10

In conclusion, according to the law of Syllogism, the statement that follows from the pair of true statement is If 4x + 5 = 13; then -5x = -10

Answer:

32.64

Step-by-step explanation:

Using the unit rate, the graphs that best represent the amount they earn for different amount of time is: C.

The slope of a graph can be interpreted as the unit rate of the scenario that is being represented by the graph. For example, money earned in dollars per hour worked is the unit rate or slope of the graph given in this scenario.

The larger the unit rate value, the steeper the slope of the line of the graph.

Let Lin's unit rate be represented as x, therefore,

Lin's unit rate = x

Diego's unit rate = 2x

Jada's unit rate = 2(2x) = 4x

This shows that unit rate of Jada is the highest, and therefore, the graph that would represent how much Jada earns would be the steepest, followed by Diego's, and the least is Lin's.

Therefore, the all the graphs would be: C.

The expected area of a circular sampling region is 531.56 m²

Given,

The radius of the circular sampling region = 13m

f(r) = [tex]\left \{ {\frac{3}{4} } \atop {0}} \right.[/tex] [1 - (13 - r)²] 12 ≤ r ≤ 14

We have to find the area of the circular sampling region = E (π r²)

E (π r²) = π E (r²)

Lets find E (r²)

E (r²) =₁₂ [tex]\int\limits^[/tex]¹⁴ r² f(r) dr

= ₁₂∫¹⁴ (3r²/4) (1 - (13 -r)²) dr

=  3/4 ₁₂∫¹⁴ r² (1 - 169 - r² + 26r) dr

= 3/4 ₁₂∫¹⁴ r² (26r³ - r⁴ - 168r²) dr

= 3/4 [ 26r⁴/4 - r⁵/5 - 168r³/3]₁₂¹⁴

= 3/4 [ (26 × 14⁴)/4 - 14⁵/5 - (168 × 14³)/3] - [ (26 × 12⁴)/4 - 12⁵/5 (168 × 12³)/3]

= 3/4 [ (26 × 38416)/4 - 537824/5 - (168 × 2744)/3] - [ (26 × 20736)/4 - 248832/5 - (168 × 1728)/3]

= 3/4 [ 249704 - 107564.8 - 153664] - [ 134784 - 49766.4 - 96768]

= 3/4 [-11524.8] - [-11750.4]

= 3/4 [225.6]

= 169.2

∴ E(r²) = 169.2

Now lets find the expected area of the circular sampling region:

Area = E(π r²) =  π E (r²)

Here, E(r²) = 169.2

So, area = π × 169.2 = 531.56 m²

That is, the expected area of a circular sampling region is 531.56 m²

Step-by-step explanation:

Our range is 0 x  10, We could also graph this with x along with the x-axis and w along the y-axis then every minute 50x gallons are gone

We have 500 gallons of the water tank and it drains at the rate of 50 gallons per minute,

.Let's suppose after 5 minutes,

W = 500 - 50 * 5W = 500 - 250W = 250

After 5 minutes, 250 gallons are left in the water tank.

Here the lowest value is 0 so our maximum time is once the tank emptied, or when w is equal to 0.

0 = 500 - 50x

50x = 500X = 500/50X = 10

So, our range is 0 x  10

Answer:

18. m<EBC = 43°, m<CBD = 47°

19. m<EBC = 50°, m<ABC = 130°

Step-by-step explanation:

18. Find m<EBC and m<CBD

m<EBC = (5x + 8) and m<CBD = (6x + 5)

these two angles add up to a right angle, therefore their sum is 90°

5x + 8 + 6x + 5 = 90

11x + 13 = 90 , 11x = 77 , x = 7

m<EBC: 5(7) + 8 = 43

m<CBD: 6(7) + 5 = 47

19. Find m<EBC and m<ABC

m<EBC = (3x + 20) and m<ABC = (17x - 40)

these two angles are supplementary, meaning that they add up to 180°

3x + 20 + 17x - 40 = 180

20x - 20 = 180, 20x = 200, x = 10

m<EBC: 3(10) + 20 = 50

m<ABC: 17(10) - 40 = 130

Answer:

1. C: y = 3x - 5

2. B: y = -3x - 9

Step-by-step explanation:

1.

y = 3x + 9; (2, 1) (parallel)

                 (x₁, y₁)

y - y₁ = m(x - x₁)

y - 1 = 3(x - 2)

y - 1 = 3x - 6

   +1         +1

-------------------

y = 3x - 5

----------------------------------------------------------------------------------------------------------

2.

y = (1/3)x - 6 ; (-3, 0) (perpendicular)

                     (x₁, y₁)

y - y₁ = m(x - x₁)

y - 0 = -3(x - (-3))

y - 0 = -3(x + 3)

y - 0 = -3x - 9

   +0          +0

----------------------

y = -3x - 9

The values of x when f(x) = 0 are 2 and 8

Graphs are used mostly to show the relationship between two variables (usually x and y).

The graph of y = f(x) is attached

To get the values of x when f(x) = 0 , we  consider where the line of the graph crosses the x-axis.

The graph crosses the x-axis at:

x = 2

x = 8

This means that the values of x when f(x) = 0 are 2 and 8

Therefore, in the graph of y = f(x), the values of x where f(x) = 0 are 2 and 8
