Answer:

Step-by-step explain

180 -(45+79) = 124

answer: 124

Step-by-step explanation:

Pythagoras must be true :

c² = a² + b²

with c being the Hypotenuse (the side opposite of the 90° angle), and it is always the longest of the 3 sides.

so, the sum of the squares of the 2 smaller numbers must be the square of the largest number.

1.3² + 2² = 1.69 + 4 = 5.69

that is NOT 3.2² = 10.24

so, this is NOT a right-angled triangle.

2.1² + 4² = 4.41 + 16 = 20.41

that is NOT 5² = 25

so, this is NOT a right-angled triangle.

5² + 12² = 25 + 144 = 169 = 13²

so, yes, this is a right-angled triangle.

Point K is located at (1, -4)

We use the rule that [tex](x,y) \to (x,-y)[/tex] when reflecting over the x axis.

The x coordinate stays the same, but the y coordinate flips from positive to negative or vice versa.

Therefore, K(1,-4) will move to K ' (1, 4)

Answer:

x= -25/4

Step-by-step explanation:

Simplify both sides of the equation:

-4(1.75+x)=18

(-4)(1.75)+ (-4)(x)=18 | Distribute

-7+-4x=18

-4x-7=18 | Then solve.

Add 7 to both sides:

-4x-7+7=18+7

-4x=25

Then divide both sides by -4

Let's use the formula to fund mean here ~

[tex] \boxed{ \sf mean = \frac{sum \: of \: all \: terms}{number \: of \: terms} }[/tex]

That is ;

[tex]\qquad \sf  \dashrightarrow \: 41 = \dfrac{32 + 31 + 42 + a + a + a}{6} [/tex]

[tex]\qquad \sf  \dashrightarrow \: (41 \times 6) = 105 + 3a[/tex]

[tex]\qquad \sf  \dashrightarrow \: 246 = 105 + 3a[/tex]

[tex]\qquad \sf  \dashrightarrow \: 3a = 246 - 105[/tex]

[tex]\qquad \sf  \dashrightarrow \: 3a = 141[/tex]

Answer:

y = 2 when x =12

Step-by-step explanation:

y = k/x ..............as y varies inversely as x

8 = k/3

k = 8 * 3

k = 24

So,

y = k/x

y = 24/12

y = 2

Answer:

"y=32"

is the answer

Step-by-step explanation:

x=3 > y=8

x=3+3+3+3=12 then y=8+8+8+8=32

Answer:

78

Step-by-step explanation:

Step-by-step explanation:

an arithmetic sequence means that every new term is the old term plus a constant number.

in our case that constant is +50.

and our starting value a0 = 250

so, the first 4 terms are

$250, $300, $350, $400

for the function formula we know

a0 = $250

a1 = a0 + 50 = 250 + 50 = $300

a2 = a1 + 50 = a0 + 50 + 50 = a0 + 2×50 = $350

a3 = a2 + 50 = a0 + 3×50 = $400

so, we see

an = a0 + n×50 = 250 + 50n

therefore,

f(n) = 250 + 50n

after 9 months saving we reached a9, meaning n=9.

f(9) = 250 + 50×9 = 250 + 450 = $700

The longer route is 4 miles further than the shorter route.

According to the concept, the square of the hypotenuse of a right triangle equaled the square of the other sides. The formula is

[tex]c^{2} = a^{2} + b^{2}[/tex],

where c is the hypotenuse length and a and b are the other two sides' lengths.

Calculate the difference between the longer route and the shorter route:

By using the Pythagorean theorem,[tex]c^{2} =a^{2} +b^{2}[/tex]

Your hypotenuse is the straight path from Crimson to Sunshine, and your legs are the roadways to and from Happy Ville. [tex]c^{2} =6^{2} +8^{2}[/tex]

Take the square root of both sides of the equation to eliminate the exponent on the left side: [tex]c=\pm \sqrt{6^{2}+8^{2}}[/tex]

Raise 6 to the power of 2:[tex]c=\pm \sqrt{36+8^{2}}[/tex]

Raise 8 to the power of 2: [tex]c=\pm \sqrt{36+64}[/tex]

Add 36 and 64: [tex]c=\pm \sqrt{100}[/tex]

Rewrite 100 as [tex]10^{2}[/tex]

[tex]c=\pm \sqrt{10^{2}}[/tex]

Pull terms out from under the radical, assuming positive real numbers.

[tex]c=\pm 10[/tex]

So the distance between Crimson and Sunshine is 10 miles.It asks for the shortest path, either to Happy ville and then to Sunshine (through the legs) or to Sunshine immediately (hypotenuse),

Legs = 6+8 = 14

Hypotenuse = 10

So getting straight to Sunshine would be faster than going to Happyville than Sunshine because going straight to Sunshine is 10 miles against 14 miles for going to Happyville than sunshine.The longer path was 14 miles, while the shorter way was 10 miles, so subtract the two.14−10  = 4Hence, the longer route is 4 miles further than the shorter route.

Using the probability concept, it is found that there is a 0.0556 = 5.56% probability that she will get a sum of 11.

A probability is given by the number of desired outcomes divided by the number of total outcomes.

In this problem:

Then:

[tex]p = \frac{2}{36} = \frac{1}{18} = 0.0556[/tex]

0.0556 = 5.56% probability that she will get a sum of 11.

Let's solve these questions :

[tex]27x^3+1=0[/tex]

Taking 1 to the right side as 0 has no use in the equation,

[tex]↪ 27{x}^{3} = - 1[/tex]

[tex]↪ {x}^{3} = - \frac{1}{27} [/tex]

[tex]↪x = \sqrt[3]{ - \frac{1}{27} } [/tex]

Now, as 27 is the cube of 3,

[tex]↪x = - \frac{1}{3} [/tex]

So, [tex]x = \frac{1}{3} [/tex]

[tex]x^3-27=0[/tex]

Taking the negative 27 to the right side, it becomes positive.

[tex]↪ {x}^{3} = 27[/tex]

[tex]↪x = \sqrt[3]{27} [/tex]

[tex]↪x = 3[/tex]

So value of x is 3

Answer:

Step-by-step explanation:

These questions are both to practice factoring a "sum/difference of two cubes" Someone else back in the 1500's figured out how to factor this. We just have to follow the pattern. Memorize this pattern.

The sum or difference of two cubes factors into a binomial and a trinomial. For the binomial just peel off the exponent (the 3rd power) from both terms and thats the first factor. For the trinomial, change the power to a 2 for both terms, but put in between them another term that is the the two terms multiplied together.

Lets look at your #6)

27x^3 + 1

Rewrite 27 as 3^3 and 1 as 1^3.

(3x)^3 + 1^3

FIRST FACTOR:

Just rip off the exponents:

(3x + 1)

SECOND FACTOR:

(3x)^2 - 3x + 1^2

^^^see the first and last terms are the 3x and the 1 but now they have a exponent, power of 2.

In between the multiply the 3x and the 1 times together.

The binomial has the Same sign as your original question. The trinomial has signs Opposite, then the last sign is Alwayspositive. The acronym SOAP can help you remember. The + or - in the factors.

I wish this was just a factoring problem. But we have to solve too.

3x+1=0

3x = -1

x = -1/3

AND

(3x)^2 + 3x + 1 =0

9x^2 + 3x + 1 = 0

oh no, we can't factor this, we have to use Quadratic formula: a=9, b=3, c=1

x= (-3+-root(3^2-4*9*1))/2*9

x = (-3 +- root(-27))/18

x= (-3 +- 3iroot3)/18

x = (-1 +- i*root3)/6

This is two solutions. Bc of the +- in the final answer. Some texts/programs/teacher might require you to write an imaginary number in the form a+bi

So it would be:

-1/6 + (i*root3)/6 and

-1/6 - (i*root3)/6

And from above the third solution is -1/3

Answer:

y= 128,  x=52

Step-by-step explanation:

The Sum of all the angles in a quadrilateral is 360.

y is 128 because both those angles are equal

the other 2 angles are also equal to each other.

360 - 128-128= 104

104/2 is 52

Answer:

Step-by-step explanation:

y = 128

x + y = 180 {Supplementary}

x + 128 = 180

x = 180 - 128
