Answer:

The length and width of the shape that will give the maximum area is 15 meters by 15 meters

Step-by-step explanation:

Mathematically, to maximize the area of a rectangle, the shape must be a square

what we are saying is that a square is the greatest rectangle

In that case , the length and width of the rectangle must be the same

Let’s have the width as w and since it is equal to length, we have the length too as w

We are given the length of the fencing which is the perimeter

Mathematically, the formula for this is ; 4w

Thus;

4w = 60

w = 60/4

w = 15 meters

Answer:

D

Step-by-step explanation:

the two triangles are similar so the proportion of similarity is equal to 3/12=1/4=>x/x+12=1/4=>4x=x+12=>x=4

Answer:

Y =  12 x + 75

Step-by-step explanation:

y = total cost of the tour

x = how many bikes rented

75 = tour cost for a group

Answer:

[tex]-\frac{3}{2}[/tex]

Step-by-step explanation:

First, find 2 points on the graph where the line intersects.

For this example, let's use (2, -1) and (4, -4). Find the slope using the rise over run equation. See below:

[tex]Slope = \frac{rise}{run} = \frac{(2, -1)}{(4, -4)} = \frac{y2 - y1}{x2 - x1} = \frac{(-4 + 1)}{(4-2)} = -\frac{3}{2}[/tex]

Answer:

The radius of mercury is 6 times larger than the radius of hydrogen and the radius of uranium is 7 times larger than the radius of hydrogen.

Step-by-step explanation:

For mercury,

[tex]Ratio=\frac{radius of Hg}{radius of H} \\=\frac{1.5e-10}{2.5e-11} \\=6[/tex]

For uranium,

[tex]Ratio=\frac{radius of U}{radius of H} \\=\frac{1.75e-10}{2.5e-11} \\=7[/tex]

Answer:

Intersection point is: (-1/2, -1/2)

Step-by-step explanation:

Notice from the attached image of the points on the plane, that opposite vertices are for example:

(-2, 6) and (1, -7), and we know that in a square, the diagonals intersect dividing themselves in equal parts. So what we need to find is the midpoint of the segment that joins (-2, 6) and (1, -7) to find where the diagonals intersect.

We use the formula for the midpoint:

x-midpoint = (x1 + x2) / 2

y-midpoint = (y1 + y2) / 2

In the case of the points (-2, 6) and (1, -7) these become:

x-midpoint = (-2 + 1) /2 = -1/2

y-midpoint = (6 + -7) / 2 = -1/2

Answer:

She needs to do at least 8 a day

Step-by-step explanation:

Answer: 7.066666666666666

Step-by-step explanation:

The answer really depends because it does not give me information about how many assignments he will do for each day so I will have to divide the total by the number of the days

106/15= 7.06666666666

it continues so I would say 7 and a half assignments but it sounds not good because it has a repeating decimal 6 in it

What we can do is  we can tell the  answer by saying Katy at least have to do at least 7 and a half or more assignments in order to finish all the missing assignments for both history and Math

Hope the explanation and the answer make sense

Answer:

25minutes

Step-by-step explanation:

Given the following

Time Isabella started getting ready = 5:25pm

Time she finished = 5:50pm

Total number of time she took to get ready = 5:50pm - 5:25pm

Total number of time she took to get ready = 0:25pm

This means that Isabella took 25minutes to get ready

Step-by-step explanation:

Answer:

3184m²

Step-by-step explanation:

Since a field is rectangle in nature

Area of the field = Length × Width

Given

Length = 52m

Width = 42m

Substitute

Area of the field = 52×42

Area of the field = 3184m²

Hence the area of the path is 3184m²

Answer: 7 years

Step-by-step explanation:

The Chubby bunny currently weighs 5 pounds but is increasing by 3 pounds per year. Assuming we wanted to find the weight in a given year, we can assume that given year is x. The expression would be:

= 5 + 3x

The fat cat weighs 19 pounds and gains by 1 pound a year.

Expression is:

= 19 + 1x

Equate the two equations together and find x:

5 + 3x = 19 + 1x

3x - 1x = 19 - 5

2x = 14

x = 14/2

x = 7 years

Answer:

[tex]\displaystyle y = 5\sin(\frac{1}{2} x) +3[/tex]

Step-by-step explanation:

The Sine Function

The general form of the sine function (with no phase shift) is:

[tex]y = A\sin(\omega x) +M[/tex]

Where:

A = Amplitude

ω = angular frequency

M= Midline or vertical shift

The midline can be calculated as the mean value of the maximum and minimum values of the oscillation, thus:

[tex]M=\frac{8-2}{2}=3[/tex]

The amplitude is half the difference between the maximum and minimum values of the oscillation:

[tex]A=\frac{8+2}{2}=5[/tex]

The angular frequency is calculated in terms of the period T as:

[tex]\displaystyle \omega=\frac{2\pi}{T}[/tex]

Since T=4π:

[tex]\displaystyle \omega=\frac{2\pi}{4 \pi}=\frac{1}{2}[/tex]

Substituting in the general form of the sine function:

[tex]\boxed{\displaystyle y = 5\sin(\frac{1}{2} x) +3}[/tex]

The first choice is correct

Answer:

15%

Step-by-step explanation:

Formula to find percentage increase/decrease/multiplier:

NV = OV x m

In words: New value = Old value x multiplier

In this question we're looking for the m (multiplier), so rearrange the formula and make m the subject.

m = NV / OV

So NV is the increase: 3162.50

OV = 2750

So 3162.50 / 2750 = 1.15

This is the multiplier (1.15) so turn into percentage by multiplying by 100 then subtract by 100.

1.15 * 100 = 115 - 100 = 15%

And the fact that the number is postive is proof that price has increased, if it was decrease, you would be expecting a negative number. Hope you understood. :)

Answer:

Step-by-step explanation:

Given Information :

a(first term) = -3

d(common difference) :

[tex]T_2-T_1\\\\1-(-3) = 1+3\\=4[/tex]

T15 = ?

[tex]T_n = a+(n-1)d\\\\T_1_5 = -3+(15-1)4\\\\T_1_5 = -3+(14)4\\\\T_1_5 = -3 +56\\\\T_1_5=53[/tex]

Explanation:

Refer to the diagram below. We have parallelogram MNOP such that we start at M, and work counterclockwise around the figure. You could work clockwise and it would be the same idea.

We see that side MN is opposite side PO. These are the two horizontal sides. The arrow markers tell us which pairs of sides are parallel. So this is why choice D is the answer.

Answer:

a) $12

b) $0.17

c) $1.65

Step-by-step explanation:

a) 3 movie tickets cost $36. At this rate, what is the cost per ticket?

3 movie tickets = $36

1 ticket = x

Cross Multiply

3x = $36

x = $36/3

x = $12

Therefore, the cost per ticket = $12

b) 3 ice cream cones cost $.25. At this rate, how much do 2 ice cream cones cost?

3 ice cream cones = $0.25

2 ice cream cones = x

Cross Multiply

3x = 2 × $0.25

3x = $0.50

x = $0.50/3

x = $0.1666666667

Approximately = $0.17

Therefore, the cost of 2 ice cream cones = $0.17

c) 3 bananas cost $0.99. At this rate, how much do 5 bananas cost?

3 bananas = $0.99

5 bananas = x

Cross Multiply

3x = 5 × $0.99

x = 5 × $0.99/3

x = $1.65

Therefore, the cost of 5 bananas = $1.65
