Is 21, 28,35 the sides of a right triangle?

Answers

Answer 1

Answer:

yes

Step-by-step explanation:

divide each by 7 =

21/7 = 3

28/7 =4

35/7 = 5

3,4,5 are always a perfect triple, and multiples of 345 are perfect triples as well. Therefore, they are sides of a right triangle.

A dog trainer is trying to find a triangular area behind his house that encloses 1800 square feet for his dog to run. He has the first two fence posts at (6, 0) and at (0, 25). The final fence post is on the property line at x = 30. Find the point where the trainer can place the final fence post.

Answers

Answer:

[tex]C = (30,500)[/tex]

Step-by-step explanation:

Given

[tex]Area = 1800ft^2[/tex]

[tex]A = (6,0)[/tex]

[tex]B = (0,25)[/tex]

[tex]C(x,y) = (30,y)[/tex]

Required

Determine the coordinates of C

The area of triangle is calculated as thus:

[tex]Area = \frac{|A_x(B_y - C_y) + B_x(C_y - A_y) + C_x(A_y - B_y)|}{2}[/tex]

This gives:

[tex]1800= \frac{|6(25 - y) + 0(y - 0) + 30(0 - 25)|}{2}[/tex]

[tex]1800= \frac{|6(25 - y) + 30(0- 25)|}{2}[/tex]

[tex]1800= \frac{|6(25 - y) + 30(-25)|}{2}[/tex]

[tex]1800= \frac{|150 - 6y -750 |}{2}[/tex]

[tex]1800= \frac{|150 -750- 6y |}{2}[/tex]

[tex]1800= \frac{|-600- 6y |}{2}[/tex]

Multiply through by 2

[tex]2 * 1800= |-600- 6y|[/tex]

[tex]3600= |-600- 6y|[/tex]

[tex]3600= |-(600+ 6y)|[/tex]

[tex]3600= 600+ 6y[/tex]

Solve for 6y

[tex]6y = 3600 - 600[/tex]

[tex]6y = 3000[/tex]

Solve for y

[tex]y = 3000/6[/tex]

[tex]y = 500[/tex]

Hence:

The point is:

[tex]C = (30,500)[/tex]

Find the error and and the correct answer

Answers

Answer:

Error: Multiplied both sides by 3/4 instead of 4/3.

Solution: x = 16

Step-by-step explanation:

The error is that you multiplied both sides by [tex]\frac{3}{4}[/tex] instead of dividing both sides by [tex]\frac{3}{4}[/tex].

This is an error because:

[tex]\frac{3}{4} *\frac{3}{4} x\neq x[/tex]

Actually:

[tex]\frac{3}{4} *\frac{3}{4} x=\frac{9}{16} x[/tex]

What you want to do instead is divide both sides by [tex]\frac{3}{4}[/tex]. Remember, dividing both sides by [tex]\frac{3}{4}[/tex] would be the same as multiplying both sides by [tex]\frac{4}{3}[/tex].

Now, lets find the correct answer:

[tex]\frac{3}{4}x=12[/tex]

Multiply both sides by 4/3.

x = 16

So the correct answer would be x = 16.

I hope this helps. Happy studying.

solve for x 3x+10 3x -28 will mark brainest answers are 1. 33 2. 34 3. 35 4. 36 ty so much 1 left godbless ​

Answers

Answer:

1.  x = 33

Step-by-step explanation:

3x+10 + 3x -28 = 180

3x + 3x = 180 + 28 - 10

6x = 198

x = 198/6

x = 33

Answer:

33

Step-by-step explanation:

By the same side interior angle theorem, we can find that 3x + 10 and 3x - 28 are supplementary. Knowing this, we can make the equation:

(3x + 10) + (3x - 28) = 180

Now we can solve for x. Combine like terms.

6x - 18 = 180

Add 18 from both sides.

6x = 198

Divide both sides by 6.

x = 33

So the value of x would be 33.

I hope you find my answer and explanation to be helpful. Happy studying.

Peter is saving money to buy an MP3 Player. After one month, he has $50. After two months he has $85. After three months, he has $120. He plans to keep saving at the same rate. How long will it take Peter to save enough money to buy an MP3 Player that costs $295?

Answers

Answer:

9 months

Step-by-step explanation:

peter is saving 35 dollars per month.  

295=35x

295/35=8.42 which is less than 295

9 is an approximate answer

35*9 equals 315, which is enough to pay 295 and have 20 dollars left over

To convert a Unit Rate into another, we have to add or subtract a Unit Ratio to the original Unit Rate.

To convert a Unit Rate into another, we have to multiply the original Unit Rate by one or two Unit Ratios.

To convert a Unit Rate into another, we have to obtain a denominator different than one.

It is no possible to convert a Unit Rate into another.

Answers

Answer: To convert a Unit Rate into another, we have to multiply the original Unit Rate by one or two Unit Ratios.

Step-by-step explanation:

Unit rates are usually convertible to other units using multiplication and division attributes to ensure equivalence depending on preference or units being converted. Once the ratio or proportion between the two units (original and target) have been obtained, the original Unit is multiplied by the ratio of the two units to obtain the target unit rate. This way both units are equivalent to each other.

Answers

Answer:   x = 6

Step-by-step explanation:

Angles 1 and 8 are alternate exterior angles, so they are equal.

So you can create an equation to solve for x

12x−20 = 2x+40  Subtract 2x from both sides. Add 20 to both sides

10x = 60

x = 6

If you need the  m∠1, Substitute 6 for x.  (2x+40)°  2(6) +40= 12+40 m∠1= 52°

m∠8=(12x−20)°   12(6) - 20 = 72-20  m∠8 = 52°
