The total number of days for which the food supply will last is 37 days.

Given,

The number of days that the food supply would last is = ?

The number of pounds of grain = 10656 pounds

The number of cattle is = 24 cattle

The number of pounds eaten by each cow each day = 12 pounds.

Therefore if one cow eat 12 pounds a day then 24 cows=

12 × 24 = 288 pounds a day

Therefore if,

288 pounds = 1 day

10656 pounds = 10656/288

= 37 days

Therefore, the number of days that the food supply would last is  37 days.

The length of the garden is 63ft, in the rectangle

What is a rectangle?

Rectangles are quadrilaterals having four right angles in the Euclidean plane of geometry. Various definitions include an equiangular quadrilateral,

Quadrilaterals are typically four-sided closed shapes, and there are numerous varieties of them. Square, rectangle, rhombus, kite, and trapezoid are the most typical shapes. Four closed sides make up a quadrilateral. Quadrilaterals are the following figures: a four-sided figure. The form features a single set of parallel sides and no right angles.

The given perimeter is 210ft

let l be the length and 2/3 of l is the breadth.

We know that 2(a+b) = 210

2(l + 2/3l) = 210

5/3 l = 105

l = 105* 3/5 = 63ft

Hence the length of the garden is 63ft.

The given triangle  ∆QRT is isosceles triangle.

What is isosceles triangle?

  Triangles with two equal sides are referred to as isosceles triangles. Also equal are the two angles that face the two equal sides. To put it another way, "An isosceles triangle is a triangle with two congruent sides." Assume that the sides AB and AC of the triangle ABC are equal, in which case the triangle ABC is an isosceles triangle with B = C. According to the theorem, "if the two sides of a triangle are congruent, then the angle opposite to them is also congruent."

Here the given points are Q(-2,-1) , R(1,5) , T(-8,-4).

Using distance formula

Now , The Distance between the points can be measure as :

D=[tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

QR = [tex]\sqrt{(1+2)^2+(5+1)^2}[/tex]

The rules for transformation of first graph is (x + 4, y + 6).

The rules for transformation of second graph is (x + 4, y + 6).

Transform the forms on a coordinate plane by rotating, reflecting, or translating them. Felix Klein introduced transformational geometry, a fresh viewpoint on geometry, in the 19th century. In geometry, object transformations are the foundation for the majority of proofs.

In first graph it is clear that the graph is translated and the rule for first graph is (x + 4, y + 6).

Similarly, the second graph is also translated and the rule is (x+3, y).

Therefore, the rule for first graph is (x + 4, y + 6) and the rule for second graph is (x + 4, y + 6).

The area of the rectangular garden that has a 70-meter path surrounding it is: 1,176 m².

Area = length × width

Perimeter of a rectangle = length surrounding a rectangular shape = 2(length + width).

Give the following:

Perimeter of the rectangular garden = 70 meter

Length = l

Width = 2/3l

Therefore:

l + 2/3l = 70

5/3l = 70

5l = 3(70)

5l = 210

5l/5 = 210/5

l = 42

10 and 12 can go into 120. 10 can go into 5 and 2, while 12 can go into 3 and 4. 4 can be still divisible, so it would be 2 and 2.

45 is 9x5. 9 can be divisible, so you would turn them into 3 and 3.

The LCM will be the product of the largest multiple of each prime that appears on at least one list. For example, we have a 2, 3, and 5, so I’ll choose the largest multiples of each and find their product. There are three 2's, three 3's, and 5, or 8 x 9 x 5. That would get you 360.

See how you could get that with your problem?

P.S. I don't answer questions directly, instead, I use examples. Feel free to use other suggestions if this one doesn't appeal to you.

The solution to the questions are:

From the question, we have the following parameters that can be used in our computation:

Length = 350 - 2x

Width = x

The area of a rectangle is the product of its dimensions

So, we have

Area = Length x Width

Substitute the known values in the above equation, so, we have the following representation

A = (350 - 2x) * x

Evaluate

A = 350x - 2x²

Differentiate and set to 0

350 - 4x = 0

So, we have

4x = 350

Divide by 4

x = 87.5

Recall that

Length = 350 - 2x

So, we have

Length = 350 - 2 x 87.5

Evaluate

Length = 175

The area is then calculated as

Area = Length x Width

So, we have

Area = 175 x 87.5

Evaluate

Area = 15312.5 square meters

Hence, the area is 15312.5 square meters

The binomial distribution is used when there is a fixed number n of trials, with each trial having only two possible outcomes, success or failure, and trials are independent, that is, the probability of success on any trial is the same.

For item b, the parameter p is obtained as follows:

The sum of all the probabilities is of one, hence:

Given, we are asked to determine:

How many kg of an alloy with 90% copper must be added to 6 kg of another alloy with 15% copper to obtain an alloy that is 40% copper = ?

convert kg to ounces.

6kg = 211.644 ounces.

90%x+15%(211.644)=40%(211.64+x)

0.9x+0.15(211.64)=0.4(211.64+x)

0.9x+31.7466 = 84.6576 + 0.4x

0.9x - 0.4x = 84.6576 - 31.7466

0.5x = 52.911

x = 52.911/0.5

x = 105.822

now convert ounces to kg.

= 3kg

Hence approximately 3 kg of an alloy with 90% copper must be added to 6 kg of another alloy with 15% copper to obtain an alloy that is 40% copper.

The amount that the cell phone owner will pay for the overages is $14.91.

The overage is the difference between the actual usage in minutes and the estimated usage.

For instance, if the plan estimates that the phone usage per year would be 4,000 minutes, but the plan holder uses 4,010 minutes, the extra 10 minutes are regarded as overages.

The opposite of overages is underages.  If underages are part of the phone plan, the plan holder will be refunded accordingly.

Usually, overages attract a variable plan rate per minute.

Fixed charge per month = $35.98

Utilities tax APR = 6.5%

Overages = 40 minutes

Rate per overage minute = $0.35

The total charge for overage = $14 ($0.35 x 40)

Interest on the overages = $0.91 ($14 x 6.5%)

Total payment for the overages = $14.91 ($14 + $0.91)

Thus, for going over the plan by 40 minutes at $0.35 plus an APR of 6.5%, you will pay $14.91 for the overages.

The values of the vertical motion modelled by the quadratic function, h(t) = -16·t² + 54·t + 3 of the object are;

The maximum height reached is approximately 48.6 units

The time of flight is approximately 3.4 seconds

A quadratic function is a polynomial of the form y = a·x² + b·x + c, where the value of a is larger than or lesser than 0

First part;

The function, for the vertical motion, h(t) = -16·t² + 54·t + 3, is a quadratic function;

The maximum height is found by using the equation that gives the value of x at the maximum value, which is presented as follows;

At the maximum point, [tex]x = \dfrac{-b}{2\cdot a}[/tex]

From the equation, a = -16, b = 54, c = 3, and x = t, which gives;

[tex]t = \dfrac{-54}{2\times (-16)} = 1.6875[/tex]

The maximum height is therefore;

h(1.6875) = -16 × 1.6875² + 54 × 1.6875 + 3 = 48.6

The time the object is in the air is found using the equation;

h(t) = 0 = -16·t² + 54·t + 3

Using the quadratic formula, [tex]x= \dfrac{-b\pm \sqrt{b^2 - 4\cdot a \cdot c} }{2 \cdot a}[/tex], we have;

[tex]t= \dfrac{-54\pm \sqrt{54^2 - 4\times (-16)\times 3} }{2 \times (-16)}=\dfrac{27\pm \sqrt{777} }{16}[/tex]

The time of flight is therefore;

[tex]t=\dfrac{27+ \sqrt{777} }{16}\approx 3.4[/tex]
