Ma poate ajuta cineva la acesta problema: pe o drepta g considerati punctele D, R,P si T coliniare in aceasta ordine astfel incat DR=PT=3 cm, iar RP=4cm

Step-by-step explanation:

3 pairs of flip flops = 14.95 x 3 = 44.85

Total amount spent = 44.85 + 21.50 + 9.99 + 15. 44 = 91.78

After adding tax = 91.78 + 7.34 = 99.12

Mrs B spent 99.12 altogether

Budget = 100

Then money left = 100 - 99.12 = 0.88

Answer:

Well to find the mean of the above

take £ as sigma

therefore,

mean= £fx/£f

This simply means the sum of all the numbers divided by the number of members

therefore,

10 + 11+12+13+14+15+16+17+18= 126

And the number of figure present on the number line are 9, therefore 126 divided by 9

giving you a result of 14

Therefore the mean of the above numbers is 14.

Answer:

The person is a about 2m

The height of the person is 0.475m.

The scale factor is the ratio of the size image in scale and original size of the image.

Scale factor= new size/ original size

Here given that the length of the lorry is 9.5 m= 9.5*100 cm= 950 cm

But in scale, the length of the lorry is 10cm

scale factor =new size/ original size= 10/950= 1/95

Similarly for the person height of the person on the scale is given = 2cm

As from above it is clear that

scale factor= 1/95

new size/ original size= 1/95

2/ original size= 1/95

original size= 95/2

original size= 47.5 cm

original size= 47.5/100 m= 0.475 m

Therefore the height of the person is 0.475m.

The type of function represented in the table is linear.

Let's check the type of function represented in the table.

You can tell if a table is linear by looking at how x and y change. If, as x increases by 1, y increases by a constant rate, then a table is linear. You can find the constant rate by finding the first difference.

It can also be found by using the linear equation,

y = mx + b

where

Therefore,

The x increases by y and the y increase by a constant rate of 5.

Therefore, the function represented in the table is linear.

Answer:

- The number of small boxes that will fill the large box 1 = 64

- The number of small boxes that will fill the large box 2 = 56

Step-by-step explanation:

Complete Question

Items for a fundraiser are packaged in small boxes shaped like rectangular prisms that are 4.5 inches long, 4.5 inches wide, and 8 inches tall. To transport the items to an event, you want to know how many of the small boxes will fit in larger boxes. The larger boxes are available in two sizes. Large Box 1 is 24.25 inches long, 18 inches wide, and 24 inches tall. Large Box 2 is 20.5 inches long, 18.5 inches wide, and 24 inches tall. Both the small and large boxes must remain upright.

Solution

To know how many of the small boxes will fit in larger boxes, we need to obtain the volumes of the small box, large box 1 and large box 2.

Volume of a cuboid = L × W × H

For the small box,

Length = L = 4.5 inches

Width = W = 4.5 inches

Height = H = 8 inches

Volume of the small box = 4.5 × 4.5 × 8 = 162 in³

For large box 1,

Length = L = 24.25 inches

Width = W = 18 inches

Height = H = 24 inches

Volume of the large box 1 = 24.25 × 18 × 24 = 10,476 in³

For large box 2

Length = L = 20.5 inches

Width = W = 18.5 inches

Height = H = 24 inches

Volume of the large box 2 = 20.5 × 18.5 × 24 = 9,102 in³

The number of small boxes that'll fill the large box 1 = (10,476/162) = 64.667 = 64 small boxes (rounded down because the fraction cannot be forced into the large box 1.

The number of small boxes that will fill the large box 2 = (9,102/162) = 56.185 = 56 small boxes.

Answer:

37.7 pounds

Step-by-step explanation:

Simply subtract 54 (starting weight) by 16.3 (weight at 5 months) = the amount of weight she lost.

Answer: 4.8 hours.

Step-by-step explanation:

To find how long it would take to travel the same distance at a slower speed, find the speed the car is currently driving at.

Speed is distance over time, or in this case, miles per hour.

360 / 4 = 90 miles per hour.

The car is travelling 15 miles per hour slower, so the new speed is 90 - 15, or 75 miles per hour.

You can now use the same equation to find the time travelled:

360 / x = 75

360 = 75x

Divide both sides by 75 to get your answer:

4.8 = x

It would take the car 4.8 hours to travel the same distance.

the answer would be 27% :3

Expressions B, D and E

Step-by-step explanation:

Here, we are to select which of the options is correct.

Let’s put in mind that they bought earn $12 per hour

x represents the number of hours Tina worked this week; the total amount of money she made would thus be x * 12 = $12x

Remembering that she made $46 overtime, the total amount of money she made that we would be $12x + 46

The total amount Tammy made, earning $12 per hour and working for y hours = $12 * y = $12y

The total amount of money both made is thus;

12x + 46 + 12y

= $(12x + 12y + 46)

Now, we have similar expressions in the question;

These are; expression B, expression D and expression E

While expression B is straightforward, the others are not

expression D is gotten by factoring out 12; 12x + 12y + 46 = 12(x + y) + 46

expression E just involved putting what each of the two earned in brackets

Answer:

There are a maximum of 2 peaches in the basket.

Step-by-step explanation:

There are 30 fruits in a basket, all apples and peaches.

If 3 fruits are taken out of the basket, it is said that at least one of the 3 fruits would be an apple.

For this to be possible, it means, picking 3 fruits, at random from the basket guarantees at least 1 of them being an apple.

This means that the maximum number of peaches obtainable from the basket is 2, to guarantee a sure case of the last fruit of 3 selected fruits being an Apple. There has to be a minimum of 28 apples in the basket for this statement to be absolutely non-contestable.

Answer:

250 turkey sandwiches were delivered.

There were 230 roast beef delivered.

115 PB&J were delivered.

Step-by-step explanation:

This question is solved using a system of equations.

I am going to say that:

x is the number of turkey sandwiches.

y is the number of roast beef.

z is the number of PB&J.

Donnie delivered 595 box lunches

This means that [tex]x + y + z = 595[/tex]

There were 20 more turkey sandwiches then roast beef.

This means that [tex]x = y + 20[/tex]

There were twice as many roast beef has PB&J.

This means that [tex]y = 2z[/tex].

So in the second equation, we have that [tex]x = 2z + 20[/tex]

Replacing this in the first equation:

[tex]x + y + z = 595[/tex]

[tex]2z + 20 + 2z + z = 595[/tex]

[tex]5z = 575[/tex]

[tex]z = \frac{575}{5}[/tex]

[tex]z = 115[/tex]

115 PB&J were delivered.

[tex]x = 2z + 20 = 2*115 + 20 = 250[/tex]

250 turkey sandwiches were delivered.

[tex]x = y + 20[/tex]

So

[tex]y = x - 20 = 250 - 20 = 230[/tex]

There were 230 roast beef delivered.

Your answers are correct.

For problem 3, we use error estimation:

| (-2)ⁿ⁺¹ / (n+1)! | < 0.01

(2)ⁿ⁺¹ / (n+1)! < 0.01

By trial and error:

If n = 3, (2)ⁿ⁺¹ / (n+1)! = 0.667

If n = 5, (2)ⁿ⁺¹ / (n+1)! = 0.089

If n = 7, (2)ⁿ⁺¹ / (n+1)! = 0.006
