Unknown side is 173.2m

120×160×.5= 9600 m^2
this is bottom triangles area

100×173.2×.5=8650 m^2
this is the top triangle area

8650+9600= 18,250 m^2
total area

Find the area of each triangle and then add them together.

Bottom Triangle

A = [tex]\frac{1}{2}[/tex]b * h

  = [tex]\frac{1}{2}[/tex](160)(120)

  = 80(120)

  = 9600 m²

Top Triangle

First we need to find the side length. We can calculate the length of the hypotenuse using Pythagorean Theorem for the bottom triangle.

a² + b² = c²

120² + 160² = c²

14400 + 25600 = c²

40000 = c²

200 = c

Now we can use Pythagorean Theorem on the top triangle to find the missing side length.

a² + b² = c²

100² + b² = 200²

10000 + b² = 40000

              b² = 30000

              b ≈ 173

A = [tex]\frac{1}{2}[/tex]b * h

  = [tex]\frac{1}{2}[/tex](100)(173)

  = 50(173)

  = 8650 m²

Top Triangle + Bottom Triangle = Total Area

     8650       +        9600

                   18250

Answer: Area = 18,250 m²

[tex]\mathrm{-Austint1414}[/tex]

To find the inverse of f(x) = 5x + 4, swap x and y to get x = 5y + 4, solve for y to get y = (x - 4)/5, which is the inverse.

With the given function f(x) = 5x + 4, we first replace f(x) with y to get y = 5x + 4. We then swap x and y to get x = 5y + 4. To solve for y, we subtract 4 from both sides, giving us x - 4 = 5y. Then, we divide both sides by 5, yielding (x - 4)/5 = y. Therefore, y = (x - 4)/5, which is the inverse of the function f(x).

Bryce rides his bike 4 blocks west to school after school he rides six blocks East to the grocery store how many blocks past his house is Bryce when he arrives at the grocery store

Answers

He rode 6 blocks to the East than he rode 4 blocks to the West, so that means after he rode 6 blocks to the east he went backwards 4 blocks.

The equation is, 6-4=2 Because he only past 2 blocks from his home to arrive at the grocery store.

Final answer:

Bryce is 2 blocks past his house when he arrives at the grocery store.

Explanation:

To find out how many blocks past his house Bryce is when he arrives at the grocery store, we need to calculate the total distance he has traveled from his house to the grocery store. He rides 4 blocks west to school and then 6 blocks east to the grocery store. To find the total distance, we can subtract the distance traveled west from the distance traveled east: 6 blocks - 4 blocks = 2 blocks past his house.

I need help with this equation
A(x+b)-c=d

Answers

Reorder the terms:
a(b + x) + -1c = d
(b * a + x * a) + -1c = d
(ab + ax) + -1c = d

Solving
ab + ax + -1c = d

Solving for variable 'a'.

Move all terms containing a to the left, all other terms to the right.

Add 'c' to each side of the equation.
ab + ax + -1c + c = c + d

Combine like terms: -1c + c = 0
ab + ax + 0 = c + d
ab + ax = c + d

Reorder the terms:
ab + ax + -1c + -1d = c + -1c + d + -1d

Combine like terms: c + -1c = 0
ab + ax + -1c + -1d = 0 + d + -1d
ab + ax + -1c + -1d = d + -1d

Combine like terms: d + -1d = 0
ab + ax + -1c + -1d = 0

about 47% of the 15152 samples researchers found were bacteria. what number of dna samples were not bacteria

Answers

To find what number of DNA samples were not bacteria we have to find what was 47% of the 15,152 samples first.

We can do this by multiplying 0.47 x 15,152 = 7,121.44

Now 7,121.44 is 47% of the samples that DOES have bacteria. To find out how many do not we must subtract.

15,152 - 7,121.44 = 8,030.56

So the number of DNA samples that were not bacteria were 8,030.56.

according to the 2010 United States census the population of a town was 89154 roughly a 12% increase from 79601 in 2000 constructing Expo Neo model to predict the town's population Each decade use your model to predict the population of the town in 2040

Answers

Final answer:

To predict the population of the town in 2040 using an exponential growth model, we can use the formula P(t) = P₀ * (1 + r)^(t - t₀), where P(t) is the population at time t, P₀ is the initial population, r is the growth rate, and t₀ is the initial time. Given the population in 2010 and 2000, we can calculate the growth rate and substitute the values into the formula to predict the population in 2040.

Explanation:

To construct an exponential growth model to predict the population of the town in 2040, we can use the formula P(t) = P₀ * (1 + r)^(t - t₀), where P(t) is the population at time t, P₀ is the initial population, r is the growth rate, and t₀ is the initial time.

Given that the population in 2010 was 89154 and in 2000 was 79601, we can calculate the growth rate as follows:

Growth rate = (Population in 2010 - Population in 2000) / Population in 2000 * 100%

Growth rate = (89154 - 79601) / 79601 * 100%

Growth rate ≈ 11.98%

Now we can substitute the values into the exponential growth model and predict the population in 2040, which is 30 years after 2010:

P(2040) = 89154 * (1 + 0.1198)^(2040 - 2010)

P(2040) ≈ 89154 * 1.1198^30 ≈ 89154 * 4.676

P(2040) ≈ 417204.504

how much does the medium smoothie cost?

Answers

2 jumbo + 1 medium = 4 med + 0.15

Multiply 2 jumbo smoothies by 2 which is >> 9.90+m =4 m+0.15

9.75=3m

Divide and it'll be 3.25

3.25=m

I Actually spent a hour trying to write an answer as it also challenged me, then i saw how simple it is i wish i could take back my time


Anyways, to find out the amout a medium smoothie cost we need to find the equation for it. With the given information we can find out that the cost of 4 medium smoothies is the same as 2 jumbos and one smoothie.So first lets find out the cost of 2 smoothies, 4.95 * 2 = 9.9.Now lets plot them into an equation.

4x+0.15=9.9+x

Simplyfy the equation by removing the x from the right side

4x-x=3x      x-x=0

so now our new equation is

3x+0.15=9.9

Next lets remove the 0.15

0.15-0.15 = 0       9.9-0.15=9.75

so our new equation is now

3x=9.75

Then, we simplify the x by dividing the amount of x's it has

3x/3=x            9.75/3=3.25

So, after doing all that math, we found out that x=3.25

So each smoothie costs $3.25

so, the equation would be 4x+0.15=9.9+x

We can test it out by plotting in the situation

(3.25*4)+0.15=13.15       9.9+3.25=13.15

Don't forget to add the extra amount.

I am so glad i was able to find this out, and hope this helps you, as i had trouble with it myself, and thats coming from someone who's taking honors!

The set A= {(2,3),(5,1),(-3,-2),(0,3)} is a subset of 'R x R', the cartesian product of Real numbers and Real numbers because both elements of all pairs in the set A are real numbers.

The given set A contains ordered pairs where each pair is constituted of two elements. An ordered pair is always in the form of (a, b) where 'a' is from the first set and 'b' is from the second set in a Cartesian product.

In the given subsets:

A. N X R(Cartesian product of Natural numbers and Real numbers)

B. R X N(Cartesian product of Real numbers and Natural numbers)

C. N X N(Cartesian product of Natural numbers and Natural numbers)

D. R X R(Cartesian product of Real numbers and Real numbers)

Looking at the subset A= {(2,3),(5,1),(-3,-2),(0,3)}, we can observe the first element of each pair in the set, we have 2, 5, -3, and 0. Negative numbers and zero are not natural numbers. Therefore it can't be a subset of 'N x R' or 'N x N'. But they are real numbers. Hence, it could be either 'R x N' or 'R x R'. However, if we look at the second element of each pair, we see that they are 3, 1, -2, and 3. Among these, -2 is a negative number and is not a natural number, but is a real number. Therefore, the set A must be a subset of 'R x R', which is the cartesian product of Real numbers and Real numbers.

Final answer:

The Triangle Inequality Theorem is applied to determine the range of values for x that would make the side lengths given form a valid triangle.

Explanation:

Understanding the Triangle Inequality Theorem

The Triangle Inequality Theorem states that in any triangle, the length of any side must be less than the sum of the other two sides. For the given question, we need to use this principle to analyze the side lengths. With the two shorter sides given as [tex]\( \frac{3}{10} \) and \( x + \frac{1}{5} \)[/tex], and the longest side given as [tex]\( \frac{3}{2}x \)[/tex], we can establish the inequality:

[tex]\( \frac{3}{2}x < \frac{3}{10} + \left( x + \frac{1}{5} \right) \).[/tex]

By solving this inequality, we can find the range of possible values for x that makes the configuration a valid triangle. This problem is an application of basic geometric principles and inequalities.
