Answer:

n is equal to 17 if you want you can plug the number to both equation and try to see if both are equal if they are equal that means you did it right

Answer:

n = 17

Step-by-step explanation:

The opposite angles of a Parallelogram are equal.

So,

4n-2 = 2n+32

4n-2n = 32+2

2n = 34

Dividing both sides by 2

n = 17

Answer:

-1/3

Step-by-step explanation:

the slope is always run over rise.

In this case we ran 1 spot to the right from where the line crosses the y axis and then 3 down.

so that gives us 1/3 but since the line is negative, the slope is also negative

Answer:

no, janet could not have won 10 games because 3x is not equal to 24

Step-by-step explanation:

if janet won twice as many as nadia that means nadia times 2

so it would be 20 to add both nadia and janet it would be over 24 therefore the answer is d

hope this helps

Answer:

68 m²

Step-by-step explanation:

The area of the lawn is calculated as

area of garden - area of flower bed - area of vegetable patch

Calculating the area of each

area of rectangular garden = 14 × 10 = 140 m²

area of flower bed = [tex]\frac{1}{2}[/tex] × 3 × 8 = 12 m²

area of vegetable patch = [tex]\frac{1}{2}[/tex] × 10 × (5 + 7) = 5 × 12 = 60 m²

Thus

area of lawn = 140 - 12 - 60 = 68 m²

Answer:

My friend's mower will take approximately 0.75 h to mow the lawn alone.

Step-by-step explanation:

To solve this problem we can use the idea of average speed and apply to this problem, using the appropriate formula shown below:

[tex]speed = \frac{distance}{time}[/tex]

Where each lawn mower has a speed at which they can mown, the distance is the lawn they're mowing and the time is how long they will take to do it. In the case where my equipment is working alone, its speed "x" can be modeled as below:

[tex]x = \frac{lawn}{1.5}[/tex]

When my friend's mower does the job, its speed "y" can be seen as:

[tex]y = \frac{lawn}{time}[/tex]

When both work together the speed can be seen as:

[tex]x + y = \frac{lawn}{0.5}[/tex]

Applying the first two equations on the second, gives us:

[tex]\frac{lawn}{1.5} + \frac{lawn}{time} = \frac{lawn}{0.5}\\\frac{1}{time} = \frac{1}{0.5} - \frac{1}{1.5}\\\frac{1}{time} = 2 - 0.667\\\frac{1}{time} = 1.333\\1.333*time = 1\\time = \frac{1}{1.333} = 0.75[/tex]

My friend's mower will take approximately 0.75 h to mow the lawn alone.

Answer:

Answer:

x ≥ 2

Step-by-step explanation:

Step 1: Isolate x

6x ≥ 12

Step 2: Divide both sides by 6

x ≥ 2

And we have our answer!

Answer:

x ≥ 2

Step-by-step explanation:

6x+1 ≥ 13

Subtracting both sides by 1

6x ≥ 13-1

6x ≥ 12

Dividing both sides by 6

=> x ≥ 2

Step-by-step explanation:

Supplementary angles are two angles whose sum of the measurements is 180°. Complementary angles are two angles whose sum of the measurements is 90°. Once an angle relationship is identified, the relationship can be modeled with an equation that will find an unknown value.

Answer:

  £170,000

Step-by-step explanation:

Bianca bought the house for 1 +20% = 1.2 times Rafik's purchase price. She sold it for 1 -5% = 0.95 times what she bought it for. So, we have ...

  (Rafik's purchase price)×1.2×0.95 = £193800

  Rafik's purchase price = £193,800/(1.2×0.95) = £170,000

Rafik bought the house for £170,000.

Answer:

3(x²-4) or 3x²-12

Step-by-step explanation:

x²-4 times 3 is equal to 3x-12 which is also 3(x²-12)

Answer:

Square each side

Subtract 1  from each side

Divide by 3

Step-by-step explanation:

sqrt(3x+1) = 4

Square each side

(sqrt(3x+1))^2 = 4^2

3x+1 = 16

Subtract 1  from each side

3x+1-1 = 16-1

3x= 15

Divide by 3

3x/3 = 15/3

x = 5

Answer:

3 acute angles.

Step-by-step explanation:

Triangles have three angles. If any one angle is obtuse or right-angle, then the remaining two angles must be acute. Or else, all the 3 angles can be acute.

An example can be an equilateral triangle because it has 3 acute angles. Each angle is 60 degrees.

Answer:

0.00054

Step-by-step explanation:

Gold ball: we have one chance of choosing the correct ball from 1 to 48, so the probability is 1/48

White balls: we will pick 4 numbers from 1 to 51, so the total possibilities of groups of numbers we can choose is a combination of 51 choose 4:

C(51, 4) = 51! / (4! * 47!) = 51*50*49*48/(4*3*2)

If we want to correctly guess two numbers, we have groups of 2 winning numbers in the 4 numbers we guess, so a combination of 4 choose 2, and we also have to incorrectly guess the other 2 winning numbers in the 47 remaining numbers we didn't choose, so a combination of 47 choose 2:

C(4, 2) = 4! / (2! * 2!) = 4*3/2 = 6

C(47, 2) = 47! / (2! * 45!) = 47*46/2

The probability of the white balls case is the two combinations above over the total number of cases (the first combination we calculated):

P = C(4, 2) * C(47, 2) / C(51, 4)

P = (6 * 47 * 46/2) / (51 * 50 * 49 * 48/(4*3*2))

P = (3 * 47 * 46 * 4 * 3 * 2) / (51 * 50 * 49 * 48) = 0.026

Then the final probability is the probability in the gold ball case times the probability in the white balls case:

P = (1/48) * (3 * 47 * 46 * 4 * 3 * 2) / (51 * 50 * 49 * 48) = 0.00054

Answer:

To check all the events (6), we label the chips. Suppose one chip with 1 is labeled R1 and the other B1 (as if they were red and blue). Now, lets take all combinations; for the first chip, we have 4 choices and for the 2nd chip we have 3 remaining choices. Thus there are 12 combinations. Since we dont care about the order, there are only 6 combinations since for example R1, 3 is the same as 3, R1 for us.

The combinations are: (R1, B1), (R1, 3), (R1, 5), (B1, 3), (B1, 5), (3,5)

We have that in 1 out of the 6 events, Miguel wins 2$ and in five out of the 6 events, he loses one. The expected value of this bet is: 1/6*2+5/6*(-1)=-3/6=-0.5$. In general, the expected value of the bet is the sum of taking the probabilities of the outcome multiplied by the outcome; here, there is a 1/6 probability of getting the same 2 chips and so on. On average, Miguel loses half a dollar every time he plays.

please mark me brainliest :)

Answer:

x = 60 and y = 100

Step-by-step explanation:

As shown in the table, you have: x + y = 160

Otherwise, you have x:y = 3:5 or x = 3y/5

=> 3y/5 + y = 160

or 8y/5 = 160

or y/5 = 20

or y = 20*5 = 100

=> x = 160 - y = 160 - 100 = 60

=> x = 60 and y = 100

Answer:

x^2-6x + 14

Step-by-step explanation:

Here, we want to

write the standard form of the quadratic equation in the question.

This can be written by expanding the bracket.

F(x) = (x-3)^2 +5

F(x) = (x-3)(x-3) + 5

F(x) = x(x-3)-3(x-3) +5

F(x) = x^2 -3x-3x + 9 + 5 = x^2-6x + 14

Step-by-step explanation:

Step 1: Define

3(14 + x) = 57

Step 2: Solve for x

Answer:

x=5

Step-by-step explanation:

First multiply 3(14+x) = 42 + 3x

Now you have the equation 42 + 3x =57

Then subtract 42 from both sides

The equation would be 3x = 15

Divide 3 from each side to get the x value

15/3=5

So therefore your answer would be x = 5

Answer:

12000 liters.

Step-by-step explanation:

The depth of the oil in the tank is 1.2 m.

The height of the oil is 1.2 m.

Length is 5 m and width is 2 m.

The volume of a rectangular prism is l×w×h.

5×2×1.2

= 12

The volume of the oil in the tank is 12 m³.

1 m³ = 1000 liters

12×1000 = 12000 liters.

The quantity of oil in the tank is 12000 liters.
