Answer:

80%

Step-by-step explanation:

% is out of 100 so make the denominator of 4/5 to be 100:

4/5 times 20/20 = 80/100 = 80%

Answer:

80%

Step-by-step explanation:

4 divided by 5 equal .8

.8 x 100 equals 80

It's multiplied by 100 because usually percentages are out of 100.

You can move the decimal in .8 to 2 space to the right

Answer:

Well, 1000>(15x+t)+(50x+100t) if there are children aboard.

B. The maximum amount is 19 if one adult is going with 18 children (not including the meal plan). And the total would be $1000

C. If only adults are going then a total of 8 adults can go if they are planning to use the raffle ticket for the meal plan too. If not then the total is 10.

I hope this is right.

The system of inequalities to model this scenario will be -

x + y ≤ 8

75y + 63x ≤ 200

The common region in the first quadrant gives the possible pair of peoples who can go to the trip.

Given is that the Rao family won a raffle of $1,000 to spend at Dixie Amusement Park. They want to use it for a group tour and for meals. A tour can have at most 8 people in the group, and if there are children on the tour there must be at least one adult. The tour cost $250 plus $100 for each adult and $50 for each child. The meal plan for the park is $15 per person.

Assume that there are [x] children in the group and [y] adults. So, we can write -

x + y ≤ 8    ... Eq[1]

(250 + 100)y + (250 + 50)x + 15(x + y) ≤ 1000

350y + 300x + 15x + 15y ≤ 1000

375y + 315x ≤ 1000

5(75y + 63x) ≤ 1000

75y + 63x ≤ 200      ... Eq[2]

Refer tot the graph attached. The common region in the first quadrant gives the possible pair of peoples who can go to the trip.

Therefore, the system of inequalities to model this scenario will be -

x + y ≤ 8

75y + 63x ≤ 200

The common region in the first quadrant gives the possible pair of peoples who can go to the trip.

Answer:

[tex] {10}^{th} \: term = \frac{5}{512} [/tex]

Step-by-step explanation:

geometric progression formula:

[tex] {n}^{th} \: term = ar ^{n - 1} [/tex]

given:

common ratio, r = 1/2

[tex]first \: term \: = 5[/tex]

1) find the value of a

[tex] {n}^{th} \: term \: = a {r}^{n - 1} [/tex]

we're finding the 1st term, so substitute 1 into n:

[tex] {1}^{st} \: term = a( \frac{1}{2} ) {}^{1 - 1} [/tex]

first term is 5. so we substitute 5 into the equation:

[tex]5 = a(1)[/tex]

[tex]a = 5[/tex]

2) find the 10th term

we're finding the 10th term, so substitute 10 into the equation and don't forget to substitute 5 into a:

[tex] {10}^{th} \: term = 5( \frac{1}{2} ) {}^{10 - 1} [/tex]

[tex] {10}^{th} \: term = 5( \frac{1}{512} )[/tex]

[tex] {10}^{th} \: term = \frac{5}{512} [/tex]

Answer:

2,160 Hours

Step-by-step explanation:

Ok so usual i would split $540 in half so a number multiplied by two would end up as 540, and i got 270. So since each week we know Phillip earned $270 and $11.25 a hour, we can divide 270 by 11.25, which gives us $24, so that means h = 24, but on week 2 it says Phillip worked 8 hours more on week 2, so that gives us a equation of 8 x 11.25, which comes out to 90, so now we can move on to our final equation, 90 x 24, which equals 2160. Im so sorry if this is wrong

Phillip worked for 20 hours and 28 hours in 1 and 2 weeks respectively.

A unit rate means a rate for one of something. We write this as a ratio with a denominator of one. For example, if you ran 70 yards in 10 seconds, you ran on average 7 yards in 1 second. Both of the ratios, 70 yards in 10 seconds and 7 yards in 1 second, are rates, but the 7 yards in 1 second is a unit rate.

Given that, Phillip earns $11.25 per hour. During Week 1, he worked h hours. During Week 2, he worked 8 hours more than Week 1. Phillip earned $540 for both weeks,

The unit rate for the work of Phillip is given, $11.25 per hour.

Therefore, his earning for h hours = $11.25h

For (8+h) hours = $11.25(h+8)

Since, he earned $540 for both weeks,

Therefore,

11.25(h+8) + 11.25h = 540

11.25h + 90 + 11.25h = 540

22.5h = 450

h = 20

h+8 = 28

Hence, Phillip worked for 20 hours and 28 hours in 1 and 2 weeks respectively.

Answer:

x = 3

y= 12

Step-by-step explanation:

2x + 2y = 30

y - 4x = 0  /*2

2x + 2y = 30

2y - 8x = 0

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

10x = 30

x = 3

y= 12

Answer:

( 3 , 12 )

Step-by-step explanation:

2x + 2y = 30 and y - 4x = 0 are two given equation

Name The equation

2x + 2y = 30 ...(1)

y - 4x = 0

y = 4x ...(2)

Now, Put the value of y in equation 1

2x + 2y = 30

2x + 2(4x) = 30

2x + 8x = 30

10x = 30

x = 30/10

x = 3

Now,

Put the value of x in equation 2

y = 4x

y = 4(3)

y = 12

Thus, The value of x is 3 and the value of y is 12

2x + 2y = 30 ...(1)

2(3) + 2(12) = 30

6 + 24 = 30

30 = 30

y = 4x ...(2)

12 = 4(3)

12 = 12

Hence, L.H.S = R.H.S

Answer:

The total cost of making the tank equals $2,082.48

Step-by-step explanation:

Giving the following information:

The tank requires 208 sq ft of material at $9.29 per square foot.

It also requires 4.5 hours of labor at $26.40 per hour plus 1.6 hours of labor at $19.60 per hour.

To calculate the total cost, we need to multiply the unitary variable cost by the total amounts:

Direct material= 9.29*208= $1,932.32

Direct labor= 4.5*26.4 + 1.6*19.6= $150.16

The total cost of making the tank equals $2,082.48

Step-by-step explanation:

In triangle WYZ ,

[tex] {u}^{2} = {4}^{2} + {v}^{2} = 16 + {v}^{2} [/tex]

In traingle WXZ ,

[tex] {(3 + v)}^{2} = {5}^{2} + {u}^{2} [/tex]

Putting the value of U^2 in above eqn.

[tex] = > {(3 + v)}^{2} = 25 + (16 + {v}^{2} )[/tex]

[tex] = > {v}^{2} + 6v + 9 = 41 + {v}^{2} [/tex]

[tex] = > {v}^{2} - {v}^{2} + 6v = 41 - 9[/tex]

[tex] = > 6v = 32[/tex]

[tex] = > v = \frac{32}{6} = \frac{16}{3} [/tex]

Putting the value of V in eqn. below :-

[tex] {u}^{2} = 16 + { (\frac{16}{3} )}^{2} [/tex]

[tex] = > {u}^{2} = \frac{256}{9} + 16[/tex]

Answer:

114°

Step-by-step explanation:

because they are parallel they have the same measure

The measure of angle 3 is equal to 114° when angle 7 is 114° by the corresponding angle property.

The angle is defined as the span between two intersecting lines or surfaces at or close to the point where they meet.

According to the definition of corresponding angles, when two parallel lines cross the third one, the angles that are in the same relative position at each intersection are referred to as being corresponding angles to one another.

In the image, it is given that angle 7 is 114 degrees. As in the image, the two parallel lines a and b are cut by the transversal line. The given angle 7 is 114°.

From the correspondence angle property, the two angles on the same side of the transversal line will be equal to each other. The angle 3 will be calculated as:-

∠7 = ∠3

114 =  ∠3

Therefore, angle 3 will be 114°.

Unfortunately, we only know about one diagonal being bisected, but not both, so we don't have enough info.

First, we notice that the time taken to paint a fence is inversely proportional to the number people used because as the number of people increase, the time taken to paint the fence decreases.

5 people can paint a fence in 4 hours.

1 person can paint a fence in = 5 x 4

                                                = 20 hours

10 people can paint the fence in = 20/10
