The set of whole numbers or natural numbers are the ones that appear naturally, which would go from 0 and beyond. While the set of integers are the numbers that don't have any decimal point, which would include negative numbers. Therefore the correct answer is the last option.

We know that

• The baby weighed 8.5 kg and was 60.5 cm long.

We have to transform 8.5 kg into pounds. We know that 1 kg is equivalent to 2.2 pounds. So, we just have to multiply.

Then, we transform 60.5 cm into inches. We know that 1 inch is equivalent to 2.54 cm. So,

The table of 3 × 3 such that the sum of any row, column, or even diagonal is 30.3 has been created below.

Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,

Summation = addition of two or more numbers or variable

Subtraction = Minus of any two or more numbers.

The third grid in first raw will be → 39.3 - (14.9 + 10.7) =  13.7

The third grid in second raw will be→ 39.3 - (13.7 + 11.3) = 14.3

The 2nd grid of 2nd raw will be → 39.3 - (17.9 + 11.3) = 13.1

The 1st grid in 2nd column will be→ 39.3 - (13.1+14.3) = 11.9

The 1st grid of 3rd raw will be → 39.3 - (14.9+11.9) = 12.5

The 2nd grid of 3rd raw will be → 39.3 - (12.5 + 11.3) = 15.5

Hence "The table of 3 × 3 such that the sum of any row, column, or even diagonal is 30.3 has been created below".

Answer:

151.93 bushels

Explanation:

First, let's find the volume of the truncated cone using the following equation

Where h is the height of the cone, r is the smallest radio and R is the largest radio. So, replacing h = 4 ft, r = 1.5 ft and R = 4.5 ft, we get:

Because the radius is half the diameter, so r = 3ft/2 = 1.5 ft and R = 9ft/2 = 4.5 ft.

Now, we know the volume in cubic feet. To find the volume in bushels, we will use the conversion factor 1 ft³ = 1.24 bushels.

Therefore, the answer is 151.93 bushels

A system of equations has infinite solutions when both equations are equivalent.

To check if two equations are equivalent, write both of them in the same form. If the coefficients are proportional, including the constant terms, then they are equivalent.

Option 1

The first equation is written in general form. Isolate the constant term on the second equation to write it in general form:

Notice that if we multiply the second equation by 3 on both sides, we will get the same coefficients as in equation 1:

Then, both equations are equivalent.

Therefore, this system has infinite solutions.

Option 2

Since there is no constant term in the secon

If c is the bill that Lottie pays for cable, the given situation can be represented by the following inequality:

25 < 3 + 5c

in the previous inequality, you have that 25 is less (<) than 3 more (3 + ) than 5 times (5x) what Lottie pays for cable.

The previous inequality can be also written as follow:

3 + 5c > 25

Answer:

[tex]y\le-\frac{1}{4}x^{2}+\frac{1}{2}x+12[/tex]

Step-by-step explanation:

It has to have a y-int of +12 so that eliminates the first 2.

It needs to be contained inside the parabola therefore the x^2 value needs to be negative.

It needs to be shifted 1/2 to the right, therefore it needs a pos x value.

If x and y are in direct proportion and y is 2 when x is 4 and  y is 6 when x is 12.

By definition of proportionality,

If y is directly proportional to x,

y α x

i,e y = k(x)

K is the constant of proportionality

when x = 4, y =2

2 = k(4) --> k = 1/2

Now y = k.x

       y = 1/2 (12)

       y = 6

The proportional constant  is a ratio that connects two given values ​​in a so-called proportional relationship. Other names for the constant of proportionality are constant ratio, constant rate, unit rate, constant of variation, or even  rate of change.

To find the constant of proportionality, first identify the variables x and y. To find out the relationship between weight and number of sticks, x is the weight and y is the number of butter sticks. Use the equation k = y÷ x to find the constant of proportionality.

We want to identify the linear function.

Of course,

a linear function is going to be a line

The vertical line test is for understanding whether it is a function or not.

By vertical line test,

Picture 1 [passes]

Picture 2 [passes]

Picture 3 [fails]

Now, we can clearly see that Option B is the a straight line, hence a linear function.

Student C raised the least amount of money after walking 8 miles.

What is mean by Ratio?

A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y.

Where, x and y are individual amount of two quantities.

Given that;

Condition for A;

The equation y = 14x represents the amount of money raised (y) for walking (x) miles.

Condition for B;

$42 is raised after walking 3 miles.

Condition for C;

Miles Walked =    6           9

Money Raised =  $72      $108

Now, For student A;

The amount of money raised for walking 8 miles will be;

⇒ y = 14x

⇒ y = 14 × 8

⇒ y = $112

So, The amount of money raised for walking 8 miles = $112

For student B;

The amount of money raised for walking 1 miles will be;

= $42 / 3

= $14 per mile

Hence, The amount of money raised for walking 8 miles will be;

= $14 x 8

= $112

So, The amount of money raised for walking 8 miles = $112

For student C;

The amount of money raised for walking 1 miles will be;

= $72 / 6

= $12 per mile

Hence, The amount of money raised for walking 8 miles will be;

= $12 x 8

= $96

So, The amount of money raised for walking 8 miles = $96

Therefore,

Student C raised the least amount of money after walking 8 miles.

A bottle of 150 vitamins costs $5.25.

The cost varies directly with the number of vitamins in the bottle.

What should a bottle with 250 vitamins cost?

Let C denotes cost and V denotes the number of vitamins.

The direct variation equation is

Let us first find the value of k (constant of proportionality)

Now the cost of 250 vitamins may be found as

Therefore, the cost of 250 vitamins is $8.75.

Answer:

Slope = -1

y-intercept = 2

Step-by-step explanation:

Equation of a line in slope-intercept form is

y = mx + b

where m = slope and b =y-intercept

Here we have

3y = -3x + 6

Dividing by 3 on both sides:
y = -1x + 2

So slope m = -1, y-intercept b = 2

Before we write the sentence comparing the densities, let's first calculate them. The density is given by the ratio between the amount of cattle and the area of the country.

The ratio for United States is:

The density of cattle for United States is 19.989 cattle/square mile.

Doing the same calculation for the other country:

The density of cattle for Republica is 40.573 cattle/square mile.

To do a relative comparison, we can do it by finding the ratio between those densities.

A sentence that makes a relative comparison would be:

The density of cattle in United States is less than the density of cattle in Republica, representing only 49.27% of the density of cattle in Republica.

People surveyed P = 200

Then

40% soccer= 200x40/100= 80

10% swimming= 200x10/100= 20

20% tennis= 200x 20/100= 40

30% basketball= 200x 30/100= 60

))How many favor soccer than swimming?

= 80 - 20= 60

Then answer is 60 people
