n = 30

Step-by-step explanation:

Step 1: Subtract 7 from both sides.

Step 2: Multiply both sides by 10.

Step 3: Check if solution is correct.

Therefore, n = 30.

The fourth step is incorrect.

Polynomial is an algebraic expression that consists of variables and coefficients. Variable are called unknown. We can apply arithmetic operations such as addition, subtraction, etc. But not divisible by variable.

Given

x² + 4x -12 is a polynomial.

              x² + 4x - 12

Step 1.    x² + 6x - 2x -12

Step 2.  (x² + 6x) - (2x + 12)

Step 3.   x(x + 6) - 2 (x + 6)

Step 4.   (x + 6)(x - 2)

Thus, in fourth step in place of (x + 2), (x - 2) is to be put.

Thus, The fourth step is incorrect.

Answer:

No, it's not long enough

Step-by-step explanation:

The perimeter of the square is 4/5. P=4s where s is the side length. 4/5 is larger than 5/8, so there will not be enough lights to cover the whole perimeter.

Answer:

B

Step-by-step explanation:

Since the triangle has 2 equal base angles (45 degrees) and 1 angle is 90 degrees, the triangle is an isosceles right triangle.

We let a be the length of one side of the right angle, so the length of the other side is also a. Applying the Pythagorean theorem we have a^2 + a^2 =14^2 => a=[tex]7\sqrt{2}[/tex]

We have the area of an equilateral triangle 1/2 the product of the lengths of the 2 sides of the right angle. S=1/2*[tex]7\sqrt{2} * 7\sqrt{2}[/tex]=49

Step-by-step explanation:

Rather than use either median or mode, he would use mean. Mean is a statistical average of numbers. It would be best to brag about the total weight that he has lost rather than using the half-way point or the most frequent appearing number in the data.

Answer:

cosθ = ( √4 - a² ) ÷ 2

Explanation:

sinθ = a/2

according to sincostan rule:

sinθ = opposite/ hypotenuse

cosθ = adjacent/ hypotenuse

so here opposite is a and hypotenuse is 2

adjacent² + opposite² = hypotenuse²

adjacent² + a² = 2²

adjacent = √4 - a²

we found our adjacent.

so cosθ = adjacent/ hypotenuse

             =  ( √4 - a² ) / 2

so cosθ = [tex]\frac{ \sqrt{4 - a^{2}} }{2}[/tex]

Answer:

y = -1.2x + 30

x = 22

x = 15

Step-by-step explanation:

Part A

Initially, Devin has $30.  Then every time he rides the bus, $1.20 is taken away:  y = 30 - 1.2x

Therefore, in slope-intercept form:  y = -1.2x + 30

If he has $3.60 on his card, then y = 3.60, so substitute this into the above equation and solve for x:

                                                  3.60 = -1.2x + 30

subtract 30 from both sides:  -26.4 = -1.2x

divide both sides by -1.2:             22 = x

Therefore Devin has ridden the bus 22 times if he has $3.60 on his card.

Part B

Rebecca:  y = -1.4x + 33

To determine how many rides on the bus Devin and Rebecca would need to take to have the same amount of value of their bus card, simply equate the equations and solve for x:

                                          Rebecca = Devin

                                                       y = y

                                         -1.4x + 33 = 30 - 1.2x

subtract 33 from both sides:   -1.4x = -3 - 1.2x

Add 1.2x to both sides:           -0.2x = -3

Divide both sides by -0.2:             x = 15

Therefore, Devin and Rebecca would both have to take 15 rides on the bus to have the same amount of value of their bus card.

Answer:

5 and -8

Step-by-step explanation:

First, list the set of pairs of numbers that multiply to give 40 (so "factors" of 40):

1  40

2  20

4  10

5  8

Now look at the pairs to see which has a difference of 3.

1 and 40 has a difference of 39

2 and 20 has a difference of 18

4 and 10 has a difference of 6

5 and 8 has a difference of 3

Now all we need to do is determine whether 5 or 8 will be negative (if they are both negative, the product will be positive, so only one needs to be negative to have a product of -40).

As we need a final result of -3,  the two numbers will be: 5 and -8 (as 5 + - 8 = -3)

Answer:

5 and -8

Step-by-step explanation:

First I listed all the factors of 40 : 1, 2, 4, 5, 8, 10, 20 and 40.

Then out of those, I just had to find a pair with a difference of 3.

Or in other words, when I subtracted one from the other I either got 3 or -3.

The only pair that worked out that way when subtracted was 5 and 8.

However, if we multiply 5 and 8 we get 40, not -40, so something was amiss. When we add them up we have to get -3, and that only worked out if it was -8 and 5, since -8 + 5 = -3.

Therefore, the two numbers are -8 and 5

The area of a shape is the amount of space occupied by the shape

The area of the triangle is 216 square centimeters

The dimension of the triangle is given as:

Base = 27 cm

Height = 16 cm

The area of the triangle is then calculated as:

Area = 0.5 * Base * Height

So, we have:

Area = 0.5 * 27 cm * 16 cm

Evaluate the product

Area = 216 square cm

Hence, the area of the triangle is 216 square centimeters

Answer:

-1875

Step-by-step explanation:

An arithmetic sequence has a common difference as a sequence. Here the common differnece is -11.

So our sequence so far looks like,

(57,46,35,24....). We know the last term of the sequence is -207 and we need to find the nth term of that series so we use arithmetic sequence

[tex]a _{1} + (n - 1)d [/tex]

where a1 is the inital value,

d is the common differnece and n is the nth term.

We need to find the nth term so

[tex]57 + (n - 1)( - 11) = - 207[/tex]

[tex](n - 1)( - 11) = - 264[/tex]

[tex]n - 1 = 24[/tex]

[tex]n = 25[/tex]

So the 25th term of a arithmetic sequence is last term, now we can use the sum of arithmetic sequence

which is

[tex] \frac{a _{1} + a _{n} }{2} n[/tex]

[tex] \frac{57 + ( - 207)}{2} (25) = [/tex]

[tex] \frac{ - 150}{2} (25)[/tex]

[tex] - 75(25) = - 1875[/tex]

Answer:

-1875

Step-by-step explanation:

57 , 46 , ......... -207

[tex]First \ term = \ a_{1} = 57\\[/tex]

common difference = d = second term - first term = 46 - 57 = -11

[tex]n^{th} \ term = -207\\\\a + (n-1)*d=t_{n}[/tex]

57 + (n-1)* (-11) = -207

57 - 11n + 11 = -207

     -11n + 68  = -207

            -11n   = -207 - 68

             -11n  = -275

                 n = -275/-11

                n = 25

[tex]S_{n}=\dfrac{n}{2}(a_{1}+l)\\\\\\S_{25}=\dfrac{25}{2}*(57 + (-207) )\\\\\\ =\dfrac{25}{2}* (-150)\\\\\\= 25 *(-75)\\\\= -1875[/tex]

Answer:

8

Step-by-step explanation:

Look like BC is 15 and AC is 17

The Pythagorean Theorem states that a^2 + b^2 = c^2

so AC^2 = AB^2 + BC^2

17^2 = AB^2 + 15^2

289 = AB^2 + 225

AB^2 = 64

AB = 8

Answer:

First, find the answer for 36 ÷ 4. Which is 9.

Now calculate each expression until you get the answer of 9.

4 ÷ 36 = 4 * 1/36 = 4/36 = 1/9

36 ÷ 1/4 = 36 * 4 = 144

1/36 * 1/4 = 1/144

36 * 1/4 = 36/4 = 9

So, the last option is the answer. D. 36 * 1/4.

Answer:

Step-by-step explanation:

The amplitude always comes before the operation(cos, tan...)

Step-by-step explanation:

the slope is the ratio "y coordinate change / x coordinate change" when going from one point on the line to another.

so, for example, when using the first 2 points (0, -5) and (1, -3) we see

x changes by +1 (from 0 to 1)

y changes by +2 (from -5 to -3).

so, the slope is +2/+1 = 2

the y-intercept is the y value when x=0. so in this case -5.

this is because it identifies the point where the line intercepts the y-axis (which is the reason why x=0).

the intercept point is then (0, -5).

Answer:

300+0.75x=y

Step-by-step explanation:

x(the number of large coffes ordered)

y(the total donation)

Answer:

y=0.75x+300

Step-by-step explanation:

So for this problem, I'm going to put it in slope-intercept form (only because it makes the most sense to me, plus if you need to graph it, this will be helpful)

So Jan is donating $300 first. So whatever you need to do, you need to add 300 afterwards to account for that donation. But then, Jan is going to donate $0.75 for every large coffee ordered. This is means it is a dependent variable. The amount is dependent on how many large coffees ordered.

Say, for example, there were 15 large coffees ordered. You should multiply 0.75*15, which will give you a product of 11.25. So for all the coffees ordered, Jan will donate a total of $11.25 (which isn't a lot, but that's okay). But that isn't ALL the money that Jan donated because, as stated before, Jan is going to donate $300 regardless of how many coffees ordered. So the total amount of money donated is $311.25
