Answer:

33.8

Step-by-step explanation:

1) Use Phythagoras theorem to get RS ↓

[tex]9.1 ^{2} + 6 ^{2} = 118.81 \\ \sqrt{118.81 } = 10.9[/tex]

2) RS = RQ

therefore, to get the perimeter, you'll have to total up the sides of the triangle ↓

[tex]rs + rq +qt + ts \\ = 10.9 + 10.9 + 6 + 6 \\ = 33.8[/tex]

Step-by-step explanation:

Compute x/y if

x + 1/y = 4 and

y + 1/x = 1/4

Please explain the process on how to solve it- I'll give brainliest!

Answers

Answer:

Y = 1/4x-1

X = 4y-1

Step-by-step explanation:

layout the equations :

x+1/y = 4        y+1/x = 1/4

solve the equations, remember to switch sides switch signs solving the equations will give us the value of the letter

x+1/y = 4

x+1 = 4y

x=4y-1

***

y+1/x = 1/4

y+1  = 1/4x

y = 1/4x-1

Let first consider the equations one by one and will be solving one by one ;

[tex]{:\implies \quad \sf x+\dfrac{1}{y}=4}[/tex]

Multiplying both sides by y will lead ;

[tex]{:\implies \quad \sf xy+1=4y}[/tex]

[tex]{:\implies \quad \boxed{\sf xy=4y-1\quad \cdots \cdots(i)}}[/tex]

Now, consider the second equation which is ;

[tex]{:\implies \quad \sf y+\dfrac{1}{x}=\dfrac14}[/tex]

Multiplying both sides by x will yield

[tex]{:\implies \quad \sf xy+1=\dfrac{x}{4}}[/tex]

[tex]{:\implies \quad \sf xy=\dfrac{x}{4}-1}[/tex]

[tex]{:\implies \quad \boxed{\sf xy=\dfrac{x-4}{4}\quad \cdots \cdots(ii)}}[/tex]

As LHS of both equations (i) and (ii) are same, so equating both will yield;

[tex]{:\implies \quad \sf 4y-1=\dfrac{x-4}{4}}[/tex]

Multiplying both sides by 4 will yield

[tex]{:\implies \quad \sf 16y-4=x-4}[/tex]

[tex]{:\implies \quad \sf 16y=x}[/tex]

Dividing both sides by y will yield :

[tex]{:\implies \quad \boxed{\bf{\dfrac{x}{y}=16}}}[/tex]

Hence, the required answer is 16

The graph of the equation y=x²-2x-8 is a parabola. What is the equation of the axis of symmetry?

Answers

Answer:

x=1

Step-by-step explanation:

y=x²-2x-8

First, we solve for the vertex

The equation for the vertex is -b/2a

Substitution:

-b/2a

=-(-2)/(2*1)

=2/2

=1

Therefore the equation for the line of symmetry is x=1

Step-by-step explanation:

last week you walked your dog 12.405 miles. this week you walked your dog 15 miles. how many fewer miles did you walk last week than this week?

Answers

fewer miles = difference between the two miles in the walks.
= (15 - 12.405)miles = 2.595

The dog walked 3 miles less in last week than this week.

What is approximation?

An approximation is anything that is similar, but not exactly equal, to something else. A number can be approximated by rounding.

Given that, last week you walked your dog 12.405 miles. this week, you walked your dog 15 miles.

The dog walked in last week approx = 12 miles

The dog walked this week = 15 miles

The  fewer miles did he walked = 15-12 = 3

Hence, the dog walked 3 miles less.

Step-by-step explanation:

It is given an equation and we are to find the value of x.

[tex] \: [/tex]

Given Equation :

[tex] \\ {\longrightarrow \qquad{ \sf{5x-10=3x+2}}} \\ \\ [/tex]

Subtracting 3x from both sides we get :

[tex] {\longrightarrow \qquad{ \sf{2x-10=2}}} \\ \\ [/tex]

Adding 10 to both sides we get :

[tex] {\longrightarrow \qquad{ \sf{2x=12}}} \\ \\ [/tex]

Dividing both sides by 2 we get :

The figure is the net for a rectangular prism.

What is the surface area of the rectangular prism represented by the net?



Enter your answer in the box.

Answers

Answer:184 cm^2

Step-by-step explanation:

10*6*2=120

6*2*2=24

2*10*2=40

120+40+24=184

Answer:

184 cm²

Step-by-step explanation:

You can find the surface area of this net by finding the area of each rectangle and adding them up.

The top rectangle has dimensions of 10 and 6. You multiply them to get 60. Add in the units and the area of the top rectangle is 60 cm².

The rectangle under the one we just found the area for has the dimensions 10 and 2. Find the area. A = 20 cm².

The two rectangles to the side of the second rectangle have the dimensions of 6 and 2. The area of one is 12 cm². This means the two rectangles added together are 24 cm².

The next rectangle has the same dimensions as the first rectangle we solved. Therefore, the area is the same, which is 60 cm².

The last rectangle has the same dimensions as the second rectangle we solved. Therefore, the area is the same, which is 20 cm².

We will add the numbers altogether to find the surface area.

60 + 20 + 24 + 60 + 20 = 80 + 24 + 80 = 104 + 80 = 184 cm²

Using the given information, which statement is true?

The two triangles are not similar because x≠y .

The triangles are similar because they each have an interior angle with a measure 70°.

The two triangles are not similar because the interior angles are congruent but the side lengths are different.

The two triangles are not similar because y = 60 so it is impossible to have three congruent angles.

Answers

So first of all you can find x and y because all triangles have interior angles that add up to 180 degrees.

X= 10 degrees
Y= 60 degrees

Looking at the options, we see that the first statement is true. And if the angles are not equal, the triangles are not able to be similar.

Answers

Answer: 10,500

Step-by-step explanation:

How to calculate tax and earning

Given the following paramiters

Total amount earned by the student = $15000

Assume we have the following parameters

Earning paid off in taxes = $1500

Amount spent on living expenses = $3000

Amount she will have left = 15000 - (1500 + 3000)

Amount she will have left = 15,000 - 4500

Amount she will have left = 10,500

Hence the amount she will have left is $10,500

Answer:

$7,500

Step-by-step explanation:

First, find the amount he pays in taxes:

$15,000 x 0.1 = $1,500

Next, find the amount he pays in living expenses:

$15,000 x 0.4 = $6,000

Add the two amounts together:

$1,500 + $6,000 = $7,500

Subtract the combined amount from the original amount to find how much the student saved:

$15,000 - $7,500 = $7,500

Therefore, the college student saves $7,500.

Step-by-step explanation:

Perimeter of Semicircle

The perimeter of a semicircle is the sum of the half of the circumference of the circle and diameter. As the perimeter of a circle is 2πr or πd. So, the perimeter of a semicircle is 1/2 (πd) + d or πr + 2r, where r is the radius.

Step-by-step explanation:

1. d = 22mm

circumference = πr + d

= 22/7 × 11 + 22

= 56.57 mm

2. r = 4 inches

circumference = πr + d

= 22/7 × 4 + 8

= 20.57 Inches

3. d = 10 yards

circumference = πr+d

= 22/7 × 5 + 10

= 25.71 yards
