The quantity of food that would be needed to feed all the cubs for one year is 1825 kg

From the question, we are to determine how much food would be needed to feed all the cubs for one year

From the given information,

"Each cub eats 1.25 kg of food a day"

Assume there are 365 days in a year.

Since there are 4 cubs,

The quantity of food that would feed the cubs for one year = 365 × 4 × 1.25

The quantity of food that would feed the cubs for one year = 1825 kg

Hence, the quantity of food needed is 1825 kg

Step-by-step explanation:

Answer:

100<x<500

Step-by-step explanation:

We can create a system of inequalities by using the Triangle Inequality Theorem. This theorem states that the sum of two sides on a triangle is greater than the other sides.
1.) Figure out the first inequality. This would be 300+200>x, or x<500.

2.) Figure out the second inequality. This would be x + 200 > 300, or x>100.
3.) Figure out the third inequality. This would be x + 300 > 200, or x > -100.

4.) Combine these inequalities. By combining these inequalities, we would get 100<x<500.

Applying the inscribed angle theorem, the measures of the angles and arcs in the image given are:

Arc QR = 48°

Arc RS = 96°

Arc QPS = 216°

Arc PSR = 186°

Arc SRQ = 144°

The inscribed angle theorem state that the measure of an intercepted arc is equal to twice the measure of the inscribed angle.

Find arc PSR:

Arc PSR = 2(93) [based on the inscribed angle theorem]

Arc PSR = 186°

Find arc QR:

Arc QR = 360 - arc PQ - arc PSR

Substitute

Arc QR = 360 - 126 - 186

Arc QR = 48°

Arc RS = arc PSR - arc PS

Arc RS = 186 - 90

Arc RS = 96°

Arc QPS = 126 + 90

Arc QPS = 216°

Arc PSR = arc PS + arc RS

The equation in slope intercept form of the line that passes through the points (6,1) and (3,3) is y = - 2 / 3 x +5

The equation of a line in slope intercept form can be represented as follows:

y = mx + b

where

Therefore, the equation in slope-intercept form of the line that passes through the points (6,1) and (3,3) can be represented as follows;

let's find the slope

m = 3 - 1 / 3 - 6

m =  - 2 / 3

Hence, let's find the y-intercept as follows;

using (3, 3)

y = - 2 / 3 (x) + b

A man can walk 6 kilometers in 2 hours.

A man can cover 3 miles by walking in an hour.

A machine can cut 10 potatoes in five minutes.

A machine can cut two potatoes in a minute.

30 feet equals 2 inches.

Using law of logarithm and exponent rules, the value of the unknown is 5

logarithms are the other way of writing the exponents. A logarithm of a number with a base is equal to another number. A logarithm is just the opposite function of exponentiation. For example, if 102 = 100 then log10 100 = 2.

Logₐ x = n  or   aⁿ = x

Where b is the base of the logarithmic function.

This can be read as “Logarithm of x to the base b is equal to n”.

In this case, we just need to solve for the value of b

Answer:

The history of the Earth is nothing more than the set of events, occurrences and phenomena that the same happened from its origin to the present.

Step-by-step explanation:

we know that the two angles with x are equal since they are made with the same lines

so

8x+36=5x+51

solve for x

a. subtract 36 from both sides

8x=5x+15

b. subtract 5x on both sides

3x=15

c. divide by 3

x=3

now to find z

we know a line equals 180

so

(8x+36)+z=180

plug in 3

8(3)+36+z=180

24+36+z=180

60+z=180

z=120

At year-end, Factory Overhead is debit of $34000.

What is profit and loss?

A profit and loss (P&L) statement could be a monetary report that has a outline of a company’s revenue, expenses and profit. It provides investors and alternative interested parties an insight into however an organization is working and whether or not it's the flexibility to get a profit.

Main Body:

Estimated total overhead costs = $456,000

Estimated direct labor costs = $2,280,000

Actual overhead costs= $422,000

Actual direct labor costs= $1,940,000

To calculate the factory overhead, we need to first calculate Estimated overhead rate.

Estimated overhead rate = Estimated total overhead costs / Estimated direct labor costs

= $456,000 / $2,280,000

= 0.2

= 20%

Therefore;

Actual Factory overhead = Actual direct labor cost × application rate

= $1,940,000 × 20%

= $388,000

We can get the balance in the overhead account as shown below;

Balance = Actual overhead cost - Actual cost that should be applied

= $422,000 - $388,000

= $34,000 (Debit).

Hence there is debit of $34000.

What is the Equation of line?

The equation of the line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

we have given that;

After 13 minutes, the airplane has 32,882 gallons of fuel. After 31 minutes, the airplane has 34,902.5 gallons of fuel.

Now,

Since, After 13 minutes, the airplane has 32,882 gallons of fuel. After 31 minutes, the airplane has 34,902.5 gallons of fuel.

Hence, The equation of line passes through the points (13, 32882) and (31, 34902.5)

So, We need to find the slope of the line.

Hence, Slope of the line is,

m = (y₂ - y₁) / (x₂ - x₁)

m = (32882 - 34902.5) / ((31 - 13)

m = 2020.5 / 18

m = 112.25

Thus, The equation of the line with slope 112.25 is,

⇒ y - 32885 = 112.25 (x - 13)

⇒ y - 32885 = 112.25x - 1459.25

⇒ y = 112.25x - 1459.25 + 32885

⇒ y = 112.25x + 31.425.75

Therefore, The function in f(t) form that describes the amount of fuel in the plane at time t will be:

Step-by-step explanation:

Using reciprocals:

4 divided by 5/6 = 4 x 6/5

= 24/5 = 4 4/5

To check: 4 4/5 x 5/6 = 4

You can use the same method for similar problems

Step-by-step explanation:

Note that the slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

Plug in the slope for m and the given coordinate for x and y:

9 = (7)(2) + b

9 = 14 + b

b = -5

y = 7x - 5

By finding an evaluating a linear equation we will see that it takes 24 minutes to serve a group of 8 people.

Let's assume that the relation between the number of people and the time it takes to serve them is linear.

A general linear equation is written as:

y = a*x + b

Where a is the slope and b is the y-intercept.

If the line passes through two points (x1, y1) and (x2, y2), then the slope is:

a = (y2 - y1)/(x2 - x1)

Here we have two points:

1 person, 10 minutes, written as (1, 10)

5 people, 18 minutes, written as (5, 18)

Then the slope is:

a = (18 - 10)/(5 - 1)

a = 8/4 = 2

Then the linear equation is:

y = 2x + b

To find the value of b, we can replace the values of one of the points, I will use (1, 10) so we will get:

10 = 2*1 +b

10 = 2 + b

10 - 2 = b

8 = b

The linear equation is:

y = 2x + 8

For 8 customers, the time will be:

y = 2*8 + 8

y = 24

The “edge” effect of a tetrahedral container with edge length of 1,000 mm would be 2*r*√3 (r = radius of ball, see diagram below). For a ping pong ball with a diameter of 40 mm, the edge effect would be 2*20*√3 = 69.28 mm. Subtract that from 1,000 mm and you get 930.72 mm of “available space” along the bottom row. Divide 930.72 mm by 40 mm per ball and you get 23.27. So you wouldn’t be able to fit 24 balls along the base, you’d only be able to fit 23 balls. With 23 balls, the total number that a tetrahedron could contain (T) would be T = n(n+1)(n+2)/6 = 2,300 balls, not 2,600.

What is the absolute maximum of an equation?

The highest conceivable values for f are represented by the absolute maximum (sometimes called the global maximum) of a function f(x) (x). Let's imagine the function's critical value, x=c, is present within its domain. If the inequality f(c) [tex]\geq[/tex] f(x), x is a domain, then the function f(x) is said to satisfy an absolute maximum when x=c.

To find the critical points, we find the value of f'(x) and equate to 0.

[tex]\frac{d}{dx} (\sqrt[11]{x^{2}+64} )=0[/tex]

we get x=0.

We see that f'(x) exists for all x between [-8,9].

We also find the endpoints, that is -8 and 9.

Then we calculate f(x) at critical points and endpoints.

We calculate f(x) at 0, -8, and 9.

We get,

for x=0, f(x)= [tex]2^{\frac{6}{11} }[/tex]

for x=-8, f(x)= [tex]2^{\frac{7}{11} }[/tex]

for x=9, f(x)= [tex]\sqrt[11]{145}[/tex]

We see that the value is maximum at x=9, and f(x) becomes [tex]\sqrt[11]{145}[/tex].

Hence we get the absolute maximum is [tex](x,f(x))\\[/tex] = [tex](9,\sqrt[11]{145} )[/tex] = [tex](9,1.6)[/tex]
