a. is in the diagram

The total number of pounds of oranges that they collected is

212 + 3.25 + 438 = 653.25 pounds

Given that they put them in one basket and they each peeled the same amount, then the number of pounds that each would peel is

653.25/3 = 217.75

Each peeled 217.75 pounds

Answer:

For maximum area: Its a square of dimensions 7.25 * 7.25.

Step-by-step explanation:

We can use calculus to solve this:

Let the length of the rectangle be L and the width be W then we have

2L + 2W = 29

L + W = 14.5

W = 14.5 - L

Area = WL

A = L(14.5 - L)

A = 14.5L - L^2

We need this to be a maximum.

Finding the derivative:

dA/dW = 14.5 - 2L = 0   for a maximum

2L = 14.5

L = 7.25

Also W = 14.5 - L

= 14.5 - 7.25 = 7.25.

So the dimensions for maximum area are 7.25 * 7.25.

The  figure is a SQUARE.

The perimeter of a rectangle, is the sum of its side lengths.

The rectangle that has the maximum area when the length is 7.25 and the width is 7.25

The perimeter is given as:

\(\mathbf{P = 29}\)

Let the dimensions be l and w.

So, we have:

\(\mathbf{2( l + w) = 29}\)

Divide both sides by 2

\(\mathbf{l + w = 14.5}\)

Make l the subject

\(\mathbf{l = 14.5 - w}\)

The area of a rectangle is:

\(\mathbf{A = lw}\)

Substitute \(\mathbf{l = 14.5 - w}\)

\(\mathbf{A = (14.5 - w)w}\)

Open brackets

\(\mathbf{A = 14.5w - w^2}\)

Differentiate

\(\mathbf{A' = 14.5 - 2w}\)

Set to 0

\(\mathbf{14.5 - 2w = 0}\)

Collect like terms

\(\mathbf{2w = 14.5}\)

Divide both sides by 2

\(\mathbf{w = 7.25}\)

Recall that: \(\mathbf{l = 14.5 - w}\)

So, we have:

\(\mathbf{l = 14.5 - 7.25 = 7.25}\)

Hence, the rectangle that has the maximum area when the length is 7.25 and the width is 7.25

multiply each term by each term and sum the results

so, the right option is B

the right option is A because

if we factor this expression by any way we obtain

Answer:

1) B. The height appear to be reported because there are disproportionately more 0s and 5s.

2) A. They are likely not very accurate because they appear to be reported.

Step-by-step explanation:

The distribution table is shown below:

Last Digit           Frequency

     0                          9

     1                           1

     2                          1

     3                          3

     4                          1

     5                         11

     6                          1

     7                          0

     8                          3

     9                          1

1. Based on the distribution table, we see a very disproportionate distribution. There is a high frequency of 0's and 5's. This lays credence to the heights being reported rather than measured. As such, option B is the correct answer

B. The height appear to be reported because there are disproportionately more 0s and 5s.

2. Since the heights were reported and not measured, they are most certainly not accurate. The conclusion is that the result is not accurate. As such, option A is the correct answer

A. They are likely not very accurate because they appear to be reported.

Answer:

15 shirts

Step-by-step explanation:

Store A charges 12.50 for a custom shirt with 0.40 per each custom character. Store B charges 14.75 for the same shirt but charges 0.25 per each custom character would make the cost from both stores the same

A: 12.5 + 0.40x

B: 14.75 + 0.25x

12.5 + 0.40x = 14.75 + 0.25x

subtract 12.5 from both sides:

12.5 + 0.40x - 12.5 = 14.75 + 0.25x - 12.5

0.40x = 2.25 + 0.25x

subtract 0.25x from both sides:

0.40x - 0.25x = 2.25 + 0.25x - 0.25x

0.15x = 2.25

divide both sides by 0.15:

0.15x/0.15 = 2.25/0.15

x = 15

The search results are unrelated to the question of finding the reflection image of (5, -3) across the y-axis. To find the reflection image of a point across the y-axis, we need to change the sign of the x-coordinate of the point. Therefore, the reflection image of (5, -3) across the y-axis is (-5, -3).

Answer:

what is the y-coordinate for A?

Step-by-step explanation:

Answer:

$2.50

Step-by-step explanation:

x/5 = 1/2

x is equal to 1 because it is half of the total and 1 is half of 2.

5 is equal to 2 because it is the whole amount and 2 is also the whole amount.

If you then solve for x by doing

5(1) = 5

5/2 = 2.5

You get 2.5 or $2.50.

Answer:

simple $2.50

Step-by-step explanation:

1 pound is $5 so half of that is $2.50

Answer:

8 hours and 8 minutes

Step-by-step explanation:

there are 24 hours on the clock so if you add 6 to the 24 it would make you be at 0:00 so then you would add 2 hours and since 28 is 8 more than 20 it would be 8 hours and 8 minutes.

The amount vivian will have after 6 years of time is $13329.05.

If the initial amount (also called as principal amount) is P, and the interest rate is R% per unit time, and it is left for T unit of time for that compound interest, then the interest amount earned is given by:

\(CI = P\left(1 +\dfrac{R}{100}\right)^T - P\)

The final amount becomes:

\(A = CI + P\\A = P\left(1 +\dfrac{R}{100}\right)^T\)

We are given that;

Amount deposited= $4,000

Rate= 3.4%

Time=6 years

Now, substituting the values in the amount formula

A= 4000(1+0.034/100)^6

A= 4000*(1.222)^6

A=4000*3.332

A= 13329.05

Therefore, the amount with compound interest will be $13329.05

The property you are referring to is called the associative property of multiplication. According to this property, when multiplying three numbers, the grouping of the numbers does not affect the result. In other words, you can change the grouping of the factors without changing the product.

In the equation you provided: 3x(5x7) = (3x5)7

The associative property allows us to group the factors in different ways without changing the result. So, whether we multiply 5 and 7 first, or multiply 3 and 5 first, the final product will be the same.

To answer this question, it is necessary to use the definition of velocity, in order to get a two equations system

The answer is:

vb ( boat velocity ) = 3.5 m/h

vw ( water velocity) = 0.5 m/h

We know:

First trip, ( going to the picnic) both velocities have the same direction,

we call vb velocity of the boat,    and  vw the velocity of the water, then

3× vt  = 12

vt = vb + vw

3 × ( vb + vw ) = 12        ⇒    3×vb + 3×vw = 12     (1)

vt = vb - vw               ( we write vb - vw because they arrive at the beginning, meaning that vb > vw.

( 4× vt ) = 12

4 × ( vb - vw ) = 12       4×vb  - 4×vw = 12   (2)

We have a two equations system

3×vb + 3×vw = 12

4×vb  - 4×vw = 12

Solving for vb  and vw

3×vb = 12 -  3×vw    ⇒ vb = ( 12 -  3×vw / 3 )    ⇒ vb = 4 - vw

plugging that value in equation (2)

4 × ( 4 - vw ) - 4×w = 12    ⇒ 16 - 8 ×vw = 12

8 × vw = 4  

Hence

vw = 4/8   miles per hour ⇒      vw = 0.5 m/h

and   vb = 4 - 0.5

vb = 3.5 m/h
