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

Step-by-step explanation:

To determine housing affordability based on a $32,000 annual income, calculate 20% for the least ($6,400 per year or $533.33 per month) and 25% for the greatest amount ($8,000 per year or $666.67 per month) you should allocate to housing costs.

To calculate the least and greatest amount you should spend on housing based on an income of $32,000.00 using the 20% to 25% range, you first need to determine 20% and 25% of your annual income. The formula to calculate a percentage of a number is:

(Percentage / 100) x Total Amount

For the least amount (20%): (20 / 100) x $32,000 = $6,400 per year

For the greatest amount (25%): (25 / 100) x $32,000 = $8,000 per year

To find the monthly housing cost, divide these amounts by 12:

Least amount monthly: $6,400 / 12 = $533.33

Greatest amount monthly: $8,000 / 12 = $666.67

Therefore, you should spend between $533.33 and $666.67 per month on housing, based on the 20% to 25% range of your annual income.

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

Answer:

There are 9 quarters and 3 nickels

Step-by-step explanation:

problems used: 0.5x+0.25y=3.09

x=y+6

so substitute what x is equal to into the problem

0.5(y+6)+0.25y=3.09  <--------- distribute

0.5y+3+0.25y=3.09     <--------- Combine like terms

0.3y+3=3.09 <----------- Subtract 3 on both sided to get y by itself

0.3y=0.9 <------------ Divide by 0.3 on both sides to get what y is equal to

y=3 <-------- now substitute to find what x is equal to

x=3+6

x=9

Answer:

There are 8 nickels and 14 quarters.

Step-by-step explanation:

Let n and q represent the numbers of nickels and quarters present.  

Then q = n + 6 states that there are 6 more quarters than there are nickels.

($0.25)(q) + ($0.05)n = $3.90, in which we substitute n + 6 for q:

($0.25)(n + 6) + ($0.05)n = $3.90

Combining the n terms, we get 0.25n + 0.05n = 3.90 - 0.25*6, or:

                                                           0.30n           = 3.90 - 1.50, or:

             $2.40

n = ----------------------- = 8

               0.30

There are 8 nickels and 14 quarters.

Check:  14 quarters comes to $3.50 and 8 nickels to $0.40, and $3.50 + $0.40 sums up to $3.90.

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:

[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]

The whale is 24.54 feet away from the shoreline.

Step-by-step explanation:

Step 1:

The man is 200 feet from the ground and the angle at which he sees the whale is 7°.

So a right-angled triangle can be formed using these measurements. The angle of the triangle is 7° while the opposite side of the triangle measures x feet while the adjacent side of the triangle measures 200 feet.

We need to find the opposites side's length of the triangle.

Step 2:

Since we have the length of the adjacent side and need to calculate the length of the opposite side we use the tan of the given angle.

The opposite side of the triangle = x feet.

[tex]\tan \theta = \frac{opposite side}{adjacent side} , tan (7) = 0.1227,[/tex]

[tex]tan(7)=\frac{x}{200}, x = 0.1227 (200) = 24.54 feet.[/tex]

So the whale is 24.54 feet away from the shoreline.

To find the distance of the whale from the shoreline, set up a right triangle, use the observation tower height as one side, and apply the tangent function to the 7-degree angle of depression.

To determine how far the whale is from the shoreline, we can use trigonometry, specifically the tangent function, since we have the height of the observation tower and the angle of depression. The angle of elevation from the whale to the top of the tower would also be 7 degrees. By setting up a right triangle with the observation tower as one side, the line of sight to the whale as the hypotenuse, and the distance from the whale to the base of the tower (along the shore) as the other side, we can solve for the distance to the whale using the tangent function.

The formula to use is:

Step-by-step solution:

The distance to the whale from the base of the tower is approximately 1,630.49 feet from the shoreline (considering tan(7°) = 0.12278).

Answer:

C. Its the third graph.

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.

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.
