Answer: n=10

Step-by-step explanation:

p=2n

p-5=1.5n

- replace 2n in the 2nd equation for p

2n-5=1.5n

2n=1.5n=5

2n-1.5n=5

0.5n=5

n=10

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

Answer:

A: <5. 5 Matches <7. So whatever angle measure <5 is, that is what <7 is.

b: (4(<6)+2)

c: x=<45

Step-by-step explanation:

C:180/4 = 45

Answer:

Step-by-step explanation:

(a)<7 is 66 degrees, because <7 and <5 are vertical angles.

(b) (4x + 2) + 66 = 180

(c) (4x + 2) + 66 = 180

4x + 2 = 114

4x = 112

x = 28

Answer:

738 cubic inches

Step-by-step explanation:

V=B*H

B=base area

H is height

82*9=738

The volume of the Prism is 738 cubic inches.

Prism is "3 dimensional shape with two identical shapes facing each other".

According to the question,

The base of prism (b) = 82 square inches.

The height of  prism (h) = 9 inches

Formula for Volume of prism = base of the prism × height of the prism

= 82 × 9

= 738 cubic inches.

Hence, the volume of the Prism is  738 cubic inches

Answer:

I would say high. The data sets are completely identical besides column 17

My goodness, this is rather confusing in the way it is worded. Nevertheless, I will attempt to do what I can. Just please keep in mind that this is my own interpretation of the problem, and therefore could be... incorrect.

I think, to start out, we could set up the problem like so

15 + t ≥ 26

because t is not a set number.

Then all that is needed is to subtract 15 from both sides, and the equation becomes

t ≥ 11

So the resulting answer is t ≥ 11.

I hope that my interpretation helps.

Answer:

X = 7 :)

Step-by-step explanation:

Pythagorean theoreem: A^2 + B^2 = C^2

Now lets solve!!

5^2 + 5^2 = C^2

25 + 25 = c^2

Now we add!

25 + 25 = 50

Now we have to find the square root!!

[tex]\sqrt{50}[/tex] = 7

Have a nice day!!

Please rate and mark brainliest!!!

Answer:

x = 7

Step-by-step explanation:

All you do is use the Pythagorean theorem. The Pythagorean theorem states that A² + B² = C². The diagonal side is opposite to the 90-degree angle which means it's "C²". To find C², you add the 5² + 5² together (A² and B²). That equals 50. So C² = 50. To get rid of the square, you put the square root symbol over C² and 50. [tex]\sqrt{C^{2} } =\sqrt{50}[/tex]; C = [tex]\sqrt{50}[/tex]. You can simplify [tex]\sqrt{50}[/tex] to [tex]5\sqrt{2}[/tex] (Basically you find a square root that goes perfectly into 50 which was 25 and 2. The 25 would be canceled to 5 and the 2 would turn into [tex]\sqrt{2[/tex]). 5√2 is equal to 7.07 (Approximately). So the answer is 7.

Answer:

Let u = √x which gives u2= x and rewrite the given equation in terms of u

u = 3 - u 2 / 4

Multiply all terms by 4, simplify and write the above quadratic in standard form and solve it for u.

u 2 + 4 u - 12 = 0

Two solutions: u = - 6 and u = 2

Use the substitution used above u = √x to solve for x.

u = - 6 = √x has no solution

u = 2 = √x has solution x = 4

Below is shown the graph of the right side of the given equation when written with its right side equal to zero. The x intercept of the graph is the graphical solution to the equation as shown below.

Step-by-step explanation:

Answer: x = 4

Step-by-step explanation:

    Given:

√x = 3 - (1 / 4)x

    Rewrite:

[tex]\displaystyle \sqrt{x} = 3 - \frac{1}{4}x[/tex]

    Square both sides:

[tex]\displaystyle (\sqrt{x} )^{2} = (3 - \frac{1}{4} x)^{2}[/tex]

[tex]\displaystyle x= \frac{1}{16}x^{2} -\frac{3}{2} +9[/tex]

    Set the equation equal to 0:

[tex]\displaystyle \frac{-1}{16}x^{2} +\frac{5}{2} -9=0[/tex]

    Use the quadratic formula:

[tex]\displaystyle x=\frac{-b\sqrt{b^{2} -4ac} }{2a}[/tex]

[tex]\displaystyle x=\frac{-(\frac{5}{2})\sqrt{(\frac{5}{2})^{2} -4(\frac{-1}{16} )(-9)} }{2(\frac{-1}{16} )}[/tex]

x = 4, 36

    Plugging back into equation shows us only one answer works,

x = 4

Answer:

424 ft and 3 inches

Step-by-step explanation:

To calculate the diagonal of a square, multiply the length of the side by the square root of 2 --> d = a√2

a² + a² = diagonal²

diagonal = √(a² + a²) = √(2 x a²) which simplifies to diagonal = a√2

If area is given --> d = √(2*area)

Knowing square perimeter --> d = (perimeter/4)*√2

Answer:

the cable is  2\sqrt{41} meters long

Step-by-step explanation:

after drawing out the lengths given, you can see that you need to find the hypotenuse of a triangle with legs 10 and 8 meters long.

10^2+8^2=164

sqrt of 164 is [tex]2\sqrt{41}[/tex]

Answer:

[tex]2\sqrt{41}\: \sf m[/tex] = 12.81 m (nearest hundredth)

Step-by-step explanation:

This can be modeled as a right triangle, with:

The length of the cable is the hypotenuse.

Using Pythagoras' Theorem: [tex]a^2+b^2=c^2[/tex]

(where a and b are the legs, and c is the hypotenuse, of a right triangle)

[tex]\implies 8^2+10^2=c^2[/tex]

[tex]\implies 164=c^2[/tex]

[tex]\implies c=\sqrt{164}[/tex]

[tex]\implies c=\sqrt{4 \cdot 41}[/tex]

[tex]\implies c=\sqrt{4} \sqrt{41}[/tex]

[tex]\implies c=2\sqrt{41}\: \sf m[/tex]

Therefore, the length of the cable is [tex]2\sqrt{41}\: \sf m[/tex] = 12.81 m (nearest hundredth)

Answer: (1/2, -1)

Step-by-step explanation: The coordinates of point S can be found using the midpoint formula for the hypotenuse RT, since S is the midpoint of RT. The midpoint formula is:

Midpoint of RT = ( (x1 + x2)/2 , (y1 + y2)/2 )

Using the coordinates of R and T, we get:

Midpoint of RT = ( (-1 + 2)/2 , (1 - 3)/2 )

= (1/2, -1)

Therefore, the location of point S is (1/2, -1).
