Answer:

X=62

Step-by-step explanation:

So solving for x, we have 3x-6=180 or 3x=186. So x=62

Question

what is 2x+6+x-12=180

Answer:

Step-by-step explanation:

2x + 6 + x * 12 = 180

3x = 180 - 6 + 12

3x = 186

x = 186 : 3

x = 62

Answer: [tex]36 cm^2[/tex]

Explanation:

Since here ABCD is the parallelogram.

Where E is the mid point of the line segment BC.

And, F is the intersection point of the segments AE and BD,

Also,  Area of △BEF is 3 [tex]cm^2[/tex].

We have to find Area of parallelogram ABCD.

Since,In  ΔBEF  and ΔACD,

∠ADF=∠EBF ( because AD ║ BE )

∠DFA = ∠BFE (vertically opposite angle)

Thus, By AA similarity postulate,

[tex]\triangle BEF \sim \triangle ACD[/tex],

Thus, [tex]\frac{area of \triangle ADF }{area of \triangle BFE} =(\frac{AD}{BE})^2[/tex]

But, AD = 2 BE,

Therefore,  [tex]\frac{area of \triangle ADF }{area of \triangle BFE} =(\frac{2BE}{BE})^2[/tex] = 4/1

Thus, area of Δ ADF = [tex]12 cm^2[/tex]

Similarly, [tex]\triangle ADB \sim \triangle BAE[/tex]

Now, let the area of the triangle AFB = x [tex]cm^2[/tex]

Thus, x + 12 = 2(x+3) ( because the area of the ΔADB = 2(area of ΔBAE) )

⇒ x = 6 [tex]cm^2[/tex]

Therefore, area of ΔAFB= 6 [tex]cm^2[/tex]

⇒ area of ΔABD = 12 + 6 = 18 [tex]cm^2[/tex]

By the definition of diagonal of parallelogram,

Area of parallelogram ABCD = 2× area of Δ ABD= 2 × 18 = 36 [tex]cm^2[/tex]

Answer:

A and B.

Step-by-step explanation:

where m is the slope and c is the the y-intercept.

A. y = x + 6

For this equation m = 1

B. y = -x - 9  

For equation B, m = -1

C. y = 2x + 1  

In this equation, m = 2  

D. y = -7x - 2

In equation D, m = -7

The equation with the highest slope is D while the one with the least slope/steep is A and B.

Answer:

m = [tex]\frac{3n}{4}[/tex]

Step-by-step explanation:

given 4m + 2n = 5n ( subtract 2n from both sides )

4m = 3n ( divide both sides by 4 )

m = [tex]\frac{3n}{4}[/tex]

Answer:

m = 3/4 n

Step-by-step explanation:

4m+2n=5n

Subtract 2n from each side

4m +2n-2n = 5n-2n

4m = 3n

Divide by 4

4m/4 = 3n/4

m = 3/4 n

Answer:

12

Step-by-step explanation:

√9 = 3 and √16 = 4

3 + 4 = 7

There is the same relationship in the second and third  set of numbers.

so for 25,9 the answer is 5 + 7 = 12

Answer:

12.

Step-by-step explanation:

We have been given format of different numbers. We are asked to find the missing value for our given format.

[tex]9,16=7[/tex]

Taking square root of 9 and 16 we will get,

[tex]\sqrt{9}=3[/tex]

[tex]\sqrt{16}=4[/tex]

[tex]3+4=7[/tex]

Similarly, we can see that by taking the square root of all the on the left side of equation and adding them we get right side of equation.

[tex]\sqrt{4}=2[/tex]

[tex]\sqrt{36}=6[/tex]

[tex]2+6=8[/tex]

[tex]\sqrt{121}=11[/tex]

[tex]\sqrt{81}=9[/tex]

[tex]11+9=20[/tex]

Upon taking square root of 25 and 49 we will get,

[tex]\sqrt{25}=5[/tex]

[tex]\sqrt{49}=7[/tex]

[tex]5+7=12[/tex]

Therefore, the missing number of our given sequence is 12.

Answer:

f = 0.30(x)

Answer:

Fraction 3 over 8, because fraction 7 over 8 minus 2 times fraction 1 over 4 equals fraction 7 over 8 minus fraction 2 over 4.

Step-by-step explanation:

Rickey has [tex]\frac{7}{8}[/tex] of a cup of cereal in a bowl.

He then gave two [tex]\frac{1}{4}[/tex] or [tex]2\times \frac{1}{4}[/tex] or  [tex]\frac{2}{4}[/tex] cups of cereal from his bowl to his little sister.

Amount of cereal left in Rickey's bowl = [tex]\frac{7}{8}- \frac{2}{4}[/tex]

= [tex]\frac{7-4}{8}=\frac{3}{8}[/tex]

So, the answer is -

Fraction 3 over 8, because fraction 7 over 8 minus 2 times fraction 1 over 4 equals fraction 7 over 8 minus fraction 2 over 4.

Answer:

gain = 0

% = 0

Step-by-step explanation:

Profit

He sells one for a profit of 25% That means he sells one of them for 100% + 25% = 125%

₹1500 * 125/100 = ₹187500/100 = ₹1875

Loss

Here he sells it for 25% less than the selling price he wanted.

100% - 25% = 75%

₹1500 * 75/100 = ₹112500/100 = ₹1125

Discussion

He should make ₹1500 + ₹1500 = ₹3000 without either profit or loss.

What he actually accomplishes is ₹1125 + ₹1875 = ₹3000

So he has a net gain (loss) of 0.

The % is 0

Step-by-step explanation:

Rock the House

Cost = initial fee + hourly charge * hours

Cost = 500 + 50h

Elegant Homes

Cost = initial fee + hourly charge * hours

Cost = 0+ 75h

Cost = 75h

Set the costs equal

500+ 50h = 75h

Subtract 50 h from each side

500 = 25h

Divide by 25

500/25= 25h/25

25 =h

The costs are equal at 20 hours

If less than 20 hours it costs less at Elegant homes.

If more than 20 hours it costs less at Rock the house

Answer:

it is 70 minutes total

Step-by-step explanation:

just add them

By adding the time spent on each game, we find that Porsche spent a total of 70 minutes at Level 1 across four gaming sessions.

Porsche spent a total amount of time at Level 1 over four games by adding the time taken for each game. This is a simple addition problem. The total time taken is:

First time: 24 minutes

Second time: 18 minutes

Third time: 16 minutes

Fourth time: 12 minutes

Using mental math, we can add these up:

24 + 18 + 16 + 12 = 70 minutes

Therefore, Porsche spent 70 minutes playing at Level 1 over the course of these four games.

Answer:

120√6

Step-by-step explanation:

Simplify the 5√8 to 2√2

simplify the √18 to 3√2

so it would be √3 * 2√2 * 5 * 2√2 * 3√2

when a square root of an expression is multiplied by itself:

√3 * 2 * 2* 5 * 2 * 3√2

so as we calculate it, 2 * 2* 5 * 2 * 3 = 120 and √2 * √3 = 6

[tex]\sqrt3\\2\sqrt2\\5\sqrt8=5\sqrt{4\cdot2}=5\sqrt4\cdot\sqrt2=5(2)\sqrt2=10\sqrt2\\\sqrt{18}=\sqrt{9\cdot2}=\sqrt9\cdot\sqrt2=3\sqrt2\\\\\sqrt3\cdot2\sqrt2\cdot5\sqrt8\cdot\sqrt{18}=\sqrt3\cdot2\sqrt2\cdot10\sqrt2\cdot3\sqrt2\\\\=(2\cdot10\cdot3)(\sqrt3\cdot\sqrt2\cdot\sqrt2\cdot\sqrt2)=60\sqrt{3\cdot2}\cdot\sqrt{2\cdot2}\\\\=60\sqrt6\cdot\sqrt4=60\sqrt6\cdot2=(60\cdot2)(\sqrt6)\\\\=\boxed{120\sqrt6}[/tex]

Answer:

402.88mm³

Step-by-step explanation:

To find the answer to this, we need to find the total area of the coin and then the size of the inner coin.

As this is a cylinder, the formula is:

[tex]\pi r^{2} h[/tex]

So lets find the area of the whole coin.

The radius is 11.5 and height is 2.2

[tex]\pi * 11.5^{2} * 2.2 = 914.05[/tex]

Now, the area of the inner circle:

Radius is 8.6 and height is 2.2:

[tex]\pi * 8.6^{2} * 2.2 = 511.17[/tex]

Now to find the area of the silver ring in the coin, you subtract the inner circle measurement from the whole coin measurement:

914.05 - 511.17 = 402.88

So the volume of the outer ring is 402.88mm³

First train's speed is 363 mph

Second train's speed is 356.1 mph

=====================================

Explanation:

x = speed of first train, y = speed of second train

x+y = 719.1 because the two speeds add to this value (sum means result of addition)

x = y+6.9 due to the fact that the first train (x) is faster than the second train (y) by 6.9 mph

Use substitution to find that...

x+y = 719.1

y+6.9+y = 719.1 <--- replace x with y+6.9

2y+6.9 = 719.1

2y = 719.1-6.9 <--- subtract 6.9 from both sides

2y = 712.2

y = 712.2/2 <--- divide both sides by 2

y = 356.1

now use this y value to find x

x = y+6.9

x = 356.1+6.9

x = 363

The speed of the first train is 363 mph and the speed of the second train is 356.1 mph. To find these, we solved the equation 2x + 6.9 = 719.1, where x represents the speed of the slower train.

To solve this problem, we will use algebra to set up equations based on the information given. Let's denote the speed of the second train as x miles per hour. Accordingly, the speed of the first train is described as x + 6.9 miles per hour, since we are told it is 6.9 mph faster than the second train. The sum of their speeds is given to be 719.1 mph. Therefore, we can write the following equation to find the speeds of each train:

Hence, the speed of the second train is 356.1 mph. Now to find the speed of the first train we add 6.9 mph to the speed of the second train:

So the speed of the first train is 363 mph, and the speed of the second train is 356.1 mph.

The length of the rectangular garden will be 10 meters. Thus, the correct option is B.

Given that:

Perimeter, P = 30 meters

Relation, W = L/2

Let W be the rectangle's width and L its length.

The perimeter of the rectangle will be defined as the total length of all of its sides. So the rectangle's perimeter will be given as,

Perimeter of the rectangle = 2(L + W) units

The length of the garden is calculated as,

30 = 2(L + L/2)

30 = 2 x 3L / 2

3L = 30

L = 10 meters

Thus, the correct option is B.

Answer:

The parameters are 7 and 45.

Step-by-step explanation:

Let's model the situation.

Let h be the number of hours Jason worked in a week.

Then, his total income is calculated as follows

His hourly charges = $7

Number of hours worked = h

So, hourly charges for the hours he worked = 7h

Additional income offered by his boss = 45

So, his total income per week = 7h + 45

Here, 7, the hourly charge and 45, the additional income are the parameters.

Answer:

x = 2

Step-by-step explanation:

When 2 secants are drawn from an external point to a circle the following theorem applies

outside × whole = outside × whole, that is

(x + 1)(x + 1 + 11) = (x + 4)(x + 4 + 1) ← simplify

(x + 1)(x + 12) = (x + 4)(x + 5) ← expand factors on both sides

x² + 13x + 12 = x² + 9x + 20 ( subtract x² from both sides )

13x + 12 = 9x + 20 ( subtract 9x from both sides )

4x + 12 = 20 ( subtract 12 from both sides )

4x = 8 ( divide both sides by 4 )

x = 2
