The ratio of the perimeters of two rectangles is 5 to 8 . the perimeter of the larger rectangle is 72 inches. What is the perimeter of the smallest triangle?

Answers

Answer 1

ANSWER

45 inches.

EXPLANATION

Let the perimeter of the smaller rectangle be x.

Then, the ratio of the perimeter of the smaller rectangle to the larger rectangle is

[tex]x:72=5:8[/tex]

We change the ratio to fraction to obtain,

[tex] \frac{x}{72} = \frac{5}{8} [/tex]

Multiply both sides by 72.

[tex]x = \frac{5}{8} \times 72[/tex]

[tex]x = 5 \times 9 = 45[/tex]

The perimeter of the smaller rectangle is 45 inches.

Answer 2

Answer:

45 inches

Step-by-step explanation:

The 72 inches is 8 parts of the ratio, hence

[tex]\frac{72}{8}[/tex] = 9 inches ← 1 part of the ratio

5 parts = 5 × 9 = 45 inches ← smaller perimeter

Step-by-step explanation:

Given the question,

height at which the plane is = 900m

angle of depression = 25°

If we closely observe, the whole scene is making an right angle triangle

So, we can use trigonometry identities

a)cosФ = BD / AB

cos (90-25) = 900 / AB

Answers

Answer:

96°

Step-by-step explanation:

so we are given two angles, we can use the two angles that were given to find the angles inside the triangle (2 of them)

then once we find those two angles in the triangle, we can use those to find the third angle

then we can figure out what x is

so both a straight line and a triangle are 180°

angle 1: 180°-134° = 46°

angle 2: 180°- 130° = 50°

now we add the two angles together: 46° + 50° = 96°

one triangle = 180°

180° - 96° = 84° = angle 3

now we can find x by subtracting 84° from 180°

180°-84° = 96°

Answer:

x = 96 degrees

Step-by-step explanation:

As you know the sum of a set of exterior angles is 360 degrees

so

x + 130 + 134 = 360

x + 264 = 360

x = 360 - 264

x = 96

A city has a population of 380,000 people. Suppose that each year the population grows by 6.25 % . What will the population be after 8 years? Round to the nearest whole number.

Answers

After 8 years, the city's population will be 538,156 people.

To calculate the population after 8 years, we can use the formula for compound interest:

\[A = P(1 + r)^n\]

Where:

A = Future population

P = Initial population (380,000)

r = Annual growth rate (6.25% or 0.0625 as a decimal)

n = Number of years (8)

Plugging in these values:

\[A = 380,000(1 + 0.0625)^8\]

\[A ≈ 538,156\]

So, the population of the city after 8 years will be approximately 538,156 people.

To calculate the population after 8 years, we used the formula for compound interest, as population growth can be thought of as compounding annually.

The initial population of 380,000 is multiplied by the growth factor, which is calculated by adding 1 to the annual growth rate expressed as a decimal (0.0625).

This factor is then raised to the power of the number of years (8).

The result is approximately 538,156, rounded to the nearest whole number. This means that with an annual growth rate of 6.25%, the city's population will increase to around 538,156 people after 8 years.

The population in 8 years will be 663,994 people.

To find the population of a city after 8 years given a 6.25% annual growth rate, we use the formula for exponential growth:

Population = P(1 + r)^t

where:

P is the initial populationr is the growth rate (expressed as a decimal)t is the time in years

Given:

P = 380,000r = 0.0625t = 8

Substitute the values into the formula:

Population = 380,000 * (1 + 0.0625)⁸

Calculate:

1 + 0.0625 = 1.0625(1.0625)⁸ ≈ 1.74742Population ≈ 380,000 * 1.74742 ≈ 663,994

Rounding to the nearest whole number, the population after 8 years will be 663,994 people.

a right triangle has a leg of 11cm and a hypotenuse of 17cm what is the length of the other leg round to the nearest tenth

Answers

Answer: [tex]2\sqrt{42}cm[/tex] ≈12.96 cm

To solve this exercise you must apply the Pythagorean Theorem, which is the shown below:

[tex]a^2=b^2+c^2[/tex]

Where a is the hypotenuse and b and c are the other legs.

You know that the triangle has a leg of 11 cm and the hypotenuse is 17 cm. Therefore, you can substitute values and solve for the other leg.

Then you obtain:

[tex](17cm)^2=b^2+(11cm)^2\\b=\sqrt{(17cm)^2-(11cm)^2}\\b=2\sqrt{42}cm[/tex]

Find each angle measure

Answers

Answer:

a) UXW = 78        b) UWY = 48         c)  WZX = 48          d) XYZ = 42

Step-by-step explanation:

There are many ways you can do this, but I'll just describe one for each.

a) Angle YWV is vertical to XWZ, so they are congruent. Angle XWZ is an alternate interior angle with angle UXW, so UXW = 78.

b) All the angles that revolve around point W must add up to 360. We already know 4 angles due to vertical angles, so 78 + 78 + 54 + 54 = 264.

360 - 264 = 96.   There are two angles left, and since they are vertical they must be congruent. 96/2 = 48, so angle UWY is 48 degrees.

c) We already know that the angle vertical to UWY is 48, so WZX is also 48 degrees because they are alternate interior angles.

d) Angle UWY is 48 degrees and angle WUY is 90 degrees because of the perpendicular line. Now we can find XYZ, the remaining angle.

90 + 48 = 138.           180 - 138 = 42.          So XYZ = 42 degrees.

I hope this helped. I'm open to any questions you may have. :)

Answer:

a) UXW = 78 degrees

b) UWY = 48 degrees

c) WZX = 48 degrees

d) XYZ = 42 degrees

Step-by-step explanation:

Apply rules and theorems:

Angles in a triangle add up to 180 degrees.

Angles on a straight line add up to 180 degrees.

Right angles are 90 degrees.

Vertically opposite angles are equal.

With these we can solve for the angles.

Sierra listened to her playlist for 10 minutes. She listened to 3 songs. The first song lasted 192 seconds, and the second song lasted 231 seconds. How long was the third song?

Answers

Answer:

Step-by-step explanation:

192 + 231 =423

10 minutes is equal to 600 seconds because there are 60 seconds in every minute.

600 - 423 = 177

Final answer:

Sierra listened to a total of 600 seconds of music. After subtracting the length of the first two songs (192 seconds + 231 seconds = 423 seconds), we find the third song was 177 seconds long.

Explanation:

Sierra listened to her playlist for 10 minutes, or 600 seconds, as there are 60 seconds in a minute. She listened to 3 songs where the first song lasted 192 seconds and the second song lasted 231 seconds. To find out how long the third song was, we need to subtract the length of the first two songs from the total listening time.

The total length of the first two songs is 192 seconds + 231 seconds = 423 seconds.

So, the length of the third song is 600 seconds - 423 seconds = 177 seconds, which means the third song lasted for 177 seconds.

Solution set: s ∈ (-4, -12). The first option shows the correct number line.

Let's find the number line that shows the solution set for the inequality:

[tex]\left|\frac{s}{2}+4\right| < 2[/tex]

We can solve the inequality by splitting it into two cases, one positive and one negative, and then solving each case separately.

Steps to solve:

1. Split the inequality into two cases:

[tex]\frac{s+8}{2} < 2[/tex]

[tex]-\frac{s+8}{2} < 2[/tex]

2. Solve the first case:

[tex]2 \cdot \frac{s+8}{2} < 2 \cdot 2[/tex]

s + 8 < 2⋅2

s + 8 < 4

s < −4

3. Solve the second case:

[tex]2 \cdot \frac{-(s+8)}{2} < 2 \cdot 2[/tex]

−(s + 8) < 2⋅2

−s − 8 < 2⋅2

−s − 8 < 4

−s < 12

[tex]\frac{-s}{-1} > \frac{12}{-1}[/tex]

s > −12

4. Combine the solutions from both cases:

s < −4 or s > −12

The number line that shows the solution set for the inequality is the one with the shaded regions between −4 and −12.
