Perimeter of the new triangle is 1505 ft

Step-by-step explanation:

Perimeter of the triangle = sum of the sides = a + b + c = 215

Each side is multiplied by 7, so new sides are 7a, 7b, 7c

⇒ New perimeter = 7a + 7b + 7c = 7(a + b + c) = 7 × 215 = 1505 ft

Answer:

[tex](5 x+ 3)(x + 4)[/tex]

Step-by-step explanation:

We want to factor

[tex]5 {x}^{2} + 23x + 12[/tex]

By comparing to

[tex]a {x}^{2} + bx + c[/tex]

We have a=5, b=23, c=12

ac=60

We split the middle term with 3x+20x, since 3×20=60

This implies that:

[tex]5 {x}^{2} + 3x + 20x + 12[/tex]

Factor by grouping;

[tex]x(5 x+ 3)+ 4(5x + 3)[/tex]

We collect common factors again;

[tex](5 x+ 3)(x + 4)[/tex]

Answer:

C. Its the third graph.

1) The volume of the beach ball when fully inflated is 47690 cubic centimeters.

2) The value of x is 3.

Step-by-step explanation:

It is given that, an inflatable beach ball has a circumference of 141.3 centimeters.

1) To find the volume of the beach ball :

Use the formula for volume of sphere to find the volume of beach ball when fully inflated.

Volume of sphere = (4/3)πr³

where, r is the radius of the sphere and π has the default value of 3.14.

To find the radius :

The given circumference is 141.3 = 2πr

⇒ r = 141.3 / 2π

⇒ r = 141.3 / (2×3.14)

⇒ r = 141.3 / 6.28

⇒ r = 22.5

Now, substituting r= 22.5 in the volume of sphere formula

Volume of sphere = (4/3) ×3.14× (22.5)³

⇒ 4/3 ×3.14 ×11391

⇒ (12.56×11391) / 3

⇒ 47690 cubic centimeters

The volume of the beach ball when fully inflated is 47690 cubic centimeters.

2) The given equation is [tex]4^{x} = 64[/tex]

⇒ 64 = 4×4×4

⇒ 64 = 4³

Therefore, the value of x is 3.

Final answer:

The volume of the beach ball when fully inflated is approximately 48,000 cubic centimeters. To find the exponent x that makes the equation 4^x=64 true, we see that x must equal 3, since 64 is 4 cubed.

Explanation:

To calculate the volume of an inflatable beach ball with a circumference of 141.3 centimeters, we first need to determine its radius. The formula connecting circumference (C) and radius (r) of a sphere is C = 2πr. Using 3.14 for π, we can rearrange to find r: r = C / (2π).

r = 141.3 cm / (2 × 3.14)
  = 141.3 cm / 6.28
  = 22.5 cm (approximately)

Now, we can use the formula for volume of a sphere which is V = (4/3)πr³. Plugging in the value of the radius, we get:

V = (4/3)× 3.14 × (22.5)³
   = (4/3)× 3.14 × (11,390.625 cm³)
   = 48,000 cm³ (approximately)

The volume of the beach ball is approximately 48,000 cubic centimeters when fully inflated, rounding to the nearest whole number.

For the second part of the question, we want to find the exponent x that equates 4 raised to the power x to 64. Since 64 is 4 cubed (or 4³), we can easily see that x = 3 to make the equation 4³=64 true.

Answer:

8.431 grams>5.46 seconds>980 meters>900 miles

Precision in measurements is indicated by the level of detail or the number of decimal places. The measurements ranked from most precise to least are 8.431 grams, 5.46 seconds, 980 meters, and 900 miles.

To rank the given measurements from most precise to least precise, we need to consider how detailed the measurement is, which is often indicated by the number of decimal places or significant figures. Precision refers to how close multiple measurements are to each other, and in this context, we measure it by the detail level provided in the measurement.

8.431 grams - This measurement is the most precise since it is given to three decimal places.

5.46 seconds - The next most precise measurement, given to two decimal places.

980 meters - This measurement, although a whole number, is more precise than '900 miles' since distances in meters usually imply a more precise measurement scale in common contexts.

900 miles - The least precise measurement, with no decimal places, indicating a broad estimate of distance.

Therefore, from most to least precise, the measurements are: 8.431 grams, 5.46 seconds, 980 meters, and finally 900 miles.

Answer:

There were 6 onion rings and 2 slider in the combination meal.

Step-by-step explanation:

Let x be the number of onion rings and y be the number of slider.

Calories in one onion ring = 45 calories

Calories in one slider = 325 calories

Total number of calories = 920

Thus, we can write the equation:

[tex]45x + 325y = 920[/tex]

There are 3 times as many onion rings as the sliders.

Thus, we can write the equation:

[tex]x = 3y[/tex]

Solving the two equation by substitution method, we get,

[tex]45(3y) + 325y = 920\\460y = 920\\y = 2\\x = 3y = 3(2) = 6[/tex]

Thus, there were 6 onion rings and 2 slider in the combination meal.

The system of equations that can be used to determine the required values is:

45x + 325y = 920 equation 1

3x = y equation 2

Where:

x = total number of onions

y = total number of sliders

In order to determine the number of onions and sliders in the combination meal, equation 1 and 2 have to be solved together in order to determine the required values. This is known as solving equations simultaneously. They can be solved using two methods:

Answer:

Length= 12  ft

Width= 25 ft

Step-by-step explanation:

We will use the area of the rectangle formula to solve this question. The formula is: [tex]Area= length* width[/tex]

Let, the width of the rectangle is x, so the length is one foot more than twice it’s width, and is written as:  

width= 2x+1

Now the area of the rectangle is given as:

300 [tex]ft^2[/tex]

So using the formula of the area of a rectangle, we get:

[tex]Area= length* width\\\Rightarrow 300= x(2x+1)\\\Rightarrow 2x^2+x-300=0\\\Rightarrow x=\frac{-1 \pm \sqrt{1^2-4 \cdot \:2\left(-300\right)}}{2\cdot \:2}\\\Rightarrow x=12,\:x=-\frac{25}{2}\\[/tex]

But we will take only positive value of x, as length can't be negative.

So the dimensions of the rectangle are:

Length= 12  ft

Width= 25 ft

To solve for the dimensions of the rectangle with an area of 300 square feet and a length one foot more than twice its width, you begin with the formula for the area of a rectangle. After setting up the quadratic equation, solving it yields a width of 10 feet and a length of 21 feet, making the dimensions 10 feet by 21 feet.

To find the dimensions of a rectangle where the length is one foot more than twice its width, and the area is 300 square feet, you set up two equations based on the given information.

Let the width be w feet. Then, the length l would be 2w + 1 feet. The area A of a rectangle is given by the formula A = w × l. Substituting the known area and the expression for l, we have 300 = w × (2w + 1).

To solve for w, we should solve the quadratic equation w^2 + w - 150 = 0. Factoring the quadratic, we get (w - 10)(w + 15) = 0. This gives us two possible solutions for the width: w = 10 or w = -15. Since a negative width doesn't make sense in this context, we use w = 10 feet. The length is thus 2 × 10 + 1 = 21 feet.

Therefore, the dimensions of the rectangle are 10 feet by 21 feet.

Answer:

The domain is (2,5,-3,0)

Step-by-step explanation:

we know that

For a set of ordered pairs, the first elements of each ordered pair represents the domain of the function and second elements of each ordered pair represents the range of the function.  

The domain of a function is the set of all possible values of x

In this problem we have

[tex]A= \ [(2,3), (5,1).(-3,-2), (0, 3)\ ][/tex]

therefore

The domain is (2,5,-3,0)

Answer:

-4, -2 and 4

Step-by-step explanation:

Consider x represents the input value,

Given,

In the piece-wise function,

The first line has a closed circle at (-2, negative 2) and then goes up through (-4, 2) with an arrow instead of an endpoint.

Thus, -4 ≤ x ≤ -2.

The second line has an open circle at (2, 1) and then goes up through (5, 4) with an arrow instead of an endpoint.

Thus, 2 < x ≤ 5.

Since domain of a function is all possible input values,

Therefore, domain = [-4,-2]∪(2,5]

-6 ∉ [-4,-2]∪(2,5]

-4 ∈ [-4,-2]∪(2,5]

-2 ∈ [-4,-2]∪(2,5]

0 ∉ [-4,-2]∪(2,5]

2 ∉ [-4,-2]∪(2,5]

4 ∈ [-4,-2]∪(2,5]

Hence, -4, -2 and 4 are within the domain of the function.
