IIf two ounces of cheese has 200 calories, how many calories are in 5 ounces of cheese?

Answers

Answer:

500 calories

Step-by-step explanation:

200 / 2 = 100

1 ounce = 100 calories

5 * 100 = calories.

OR

200 * 5 = 1000

1000 / 2 = 500

Therefore, 5 ounces of cheese = 500 calories.

O 2 units
Ο Ο Ο

Answers

Answer:

The radius of the circle is:

[tex]r=4[/tex] units

Step-by-step explanation:

Given the equation

[tex]\left(x\:+\:5\right)^2\:+\:\left(y\:-\:3\right)^2=\:42[/tex]

As we know that

[tex]\left(x\:-\:a\right)^2\:+\:\left(y\:-\:b\right)^2=\:r^2\:[/tex]

is the equation of the circle with a radius 'r', centered at (a, b)

[tex]\mathrm{Rewrite}\:\left(x+5\right)^2+\left(y-3\right)^2=4^2\:\mathrm{in\:the\:form\:of\:the\:standard\:circle\:equation}[/tex]

so, the circle properties are:

[tex]\left(x-\left(-5\right)\right)^2+\left(y-3\right)^2=4^2[/tex]

Therefore, the radius of the circle is:

The larger the two numbers is one more than four times the small number. if the sum of the numbers is 106,find the two numbers ​

Answers

Answer:

Smaller no. = 21

Larger no. = 85

Step-by-step explanation:

Smaller no. = y

Larger no. = 4y + 1

y + (4y + 1) = 106

y + 4y + 1 = 106

5y + 1 = 106

5y = 106 - 1

5y = 105

y = 105/5

y = 21

Smaller no. = y = 21

Larger no. = 4y + 1 = 4×21 + 1 = 84 + 1 = 85

A triangle is formed with side lengths of 5 inches, 12 inches, and 15 inches. Is the triangle a right triangle?

Answers

Answer:

the triangle is not a right angle

Step-by-step explanation:

5²+12²=169

15²=225

The given triangle is not right angle triangle, because the given information of the triangle does not hold the Pythagoras theorem.

What are Pythagorean triplets?  

In a right-angled triangle, its side, such as hypotenuse, perpendicular and base is Pythagorean triplets.

Here,
A triangle is formed with side lengths of 5 inches, 12 inches, and 15 inches.
Verifying whether it is right angle or not,
Hypotenuse = 15
perpendicular = 12
Base = 5

Now,
Pythagoras' theorem is given as,
h² = p² + b²
15² = 12² + 5²
225 ≠ 169

Thus, the given triangle is not right angle triangle, because the given information of the triangle does not hold the Pythagoras theorem.

Vrite and simplify an expression to find he total cost of x pencils , 1 poster board , and (x + 1) notebooks.

Answers

Answer:

The expression to find the total cost of x pencils, 1 poster board, and (x + 1) notebooks will be:

[tex]C=xp+b+nx+n[/tex]

Step-by-step explanation:

Consider '[tex]x[/tex]' be the number of pencils which were bought

Consider '[tex]p[/tex]'  denotes the cost of [tex]1[/tex] pencil

Consider '[tex]b[/tex]'  denotes the cost of [tex]1[/tex] poster board

Consider '[tex]x+1[/tex]' be the number of notbooks which were bought

Consider '[tex]n[/tex]'  denotes the cost of [tex]1[/tex] notebook

As we have to find the total cost. Let 'C' denotes the total cost

so the expression becomes

[tex]C=xp+b+\left(x+1\right)n[/tex]

simplifying

[tex]C=xp+b+nx+n[/tex]

Therefore, the expression to find the total cost of x pencils, 1 poster board, and (x + 1) notebooks will be:

[tex]C=xp+b+nx+n[/tex]

a car travels from point s at (-5,7) to point t at (-5,-1). if each unit represents 20 miles, how long will it take the car to travel this distance, traveling at 40 miles per hour?

Answers

Answer:

The value is  [tex]t = 4 \ hours[/tex]

Step-by-step explanation:

From the question we are told that

  The initial  position of the car is  [tex]x_i , y_i = (-5,7)[/tex]

   The final position of the car is    [tex]x_f , y_f = (-5,-1)[/tex]

    The speed of the car is [tex]v = 40 \ miles / hour[/tex]

Generally the distance covered by the car along the x-axis is  

      [tex]x = -5 - [- 5][/tex]

=>    [tex]x = 0[/tex]

Generally the distance covered along the y-axis is  

     [tex]y = y_i - y_f[/tex]

=>[tex]y = y_i - [-1][/tex]

=>  [tex]y = 8[/tex]

Generally the resultant distance covered is  

     [tex]R = \sqrt{x^2 + y^2}[/tex]

=>   [tex]R = \sqrt{0^2 + 8^2}[/tex]

=>   [tex]R = 8[/tex]

From the question we are told that 1 unit of the distance covered is  20 miles so  

    8 units is

           [tex]r = 8 *20[/tex]

=>        [tex]r =160 \ miles[/tex]

Generally the time taken is mathematically represented as

       [tex]t = \frac{r}{v}[/tex]

=>    [tex]t = \frac{160}{ 40}[/tex]

=>    [tex]t = 4 \ hours[/tex]

create a model or equation that will represent to the amount of relief each family will receive bearing in mind that the number of families will vary.​

Answers

Missing Information

Suppose the officials conducted a survey for 4 days to determine the actual number of families residing in the barangay and the secretary constructed a tableto keep track of the data.

Day 0:

Number of families: 850

Amount of relief each family will receive: 520

Answer:

f(x) = 442000/x

Step-by-step explanation:

Given

The data in the above table

Required

Determine a model or equation

First, we need to determine the amount of relief for all families.

Using data in day 0.

Total Amount = 850 * 520

Total Amount = 442000

Next, we determine the function of equation.

Let the number of families he represented by x

The function or equation is gotten by dividing the total amount by the number of families.

Hence:

f(x) = Total Amount ÷ x

Substitute values for total amount and x

f(x) = 442000/x

Hence, the model that satisfies the given information is:

f(x) = 442000/x
