Answer:

13.6

Step-by-step explanation:

Remember SOH CAH TOA

We're going to use tangent = opposite / adjacent because the 11 is opposite theta (39 degrees) and x is adjacent to it.

tan (39) = 11 / x

x = 11 / tan(39)

x = 13.584 -> 13.6 (rounded to nearest tenth)

Note: Make sure your calculator is in degree mode.

Answer:

4 years

Step-by-step explanation:

do 1,875 divided by 768

Answer:

Step-by-step explanation:

Divide both sides by -20. If you divide by a negative, you have to switch the inequality sign. So now you have this for t:

t < 4

Draw a circle around 4 on a number line, but do not shade it in. Then everything below 4 is the right answer for the value of t.

Before we solve the equation let's take a look at it.

f(x) = -2x + 3

See how x appears in both f(x) and as the variable in the second half of the equation?

f(x) means "The function of x." You might also see g(x), h(x), and while those are the most common it can really be any letter, and any variable inside the parentheses.

So when we see f(-1), that means "The function of -1" or "The function of x when it is equal to -1."

Catching on? We need to replace x with -1 to solve for f(-1).

So here we go:

f(x) = -2x + 3

f(-1) = -2(-1) + 3

f(-1) = 2 + 3

f(-1) = 5

Voilà! We have solved for f(-1). Hope this helped.

Answer:

Tn = 8n - 2

Step-by-step explanation:

Given the arithmetic sequence

6, 14, 22, 30, 38

The nth term is expressed as;

Tn = a +(n-1)d

a is the first term = 6

d is the common difference = 14 - 6 = 22 - 14 = 8

Substitute into the formula;

Tn = 6 + (n-1)(8)

Tn = 6 + 8n-8

Tn = 8n - 2

Hence the nth term of the sequence is 8n-2

Answer:-18

Step-by-step explanation:

6(x−3)+x=7x−18

Step 1: Simplify both sides of the equation.

6(x−3)+x=7x−18

(6)(x)+(6)(−3)+x=7x+−18(Distribute)

6x+−18+x=7x+−18

(6x+x)+(−18)=7x−18(Combine Like Terms)

7x+−18=7x−18

7x−18=7x−18

Step 2: Subtract 7x from both sides.

7x−18−7x=7x−18−7x

−18=−18

Step 3: Add 18 to both sides.

−18+18=−18+18

0=0

The expression would be: m + 0.15m and to know how much she paid I believe it would be 26.09 (rounded)

Answer: x = -27

Step-by-step explanation:

Answer:

Step-by-step explanation:

[tex] step - 1 : define \\ - 8 = \frac{x}{3} + 1[/tex]

[tex]step - 2 : \\ rewrite[/tex]

[tex]\frac{x}{3} + 1= - 8[/tex]

[tex]step - 3 : \\ subtract \: 1 \: from \: both \: sides[/tex]

[tex] \frac{x}{3} + 1 - 1 = - 8 - 1[/tex]

[tex] \frac{x}{3} = - 9[/tex]

[tex]step - 4 : \\ multiply \: both \: sides \: by \: 3[/tex]

[tex] \frac{x}{3} \times 3 = - 9 \times 3[/tex]

[tex] \huge \therefore x = - 27[/tex]

Answer:

-9°F

Step-by-step explanation:

If we have a horizontal line in which the zero is in the middle, the positive numbers are on the right and the negative numbers are on the right, we would see that -9°F is further than 6°F. Even though -9°F is a smaller temperature, it is still further away from the zero.

Answer:

750/100 X 7 = 52.50

52.50 X 3 = $157.50

Step-by-step explanation:

divide principal amount by 100 then multiply by interest percentage. this gave 52.50

now multiply the interest amount by number of years

in this case 3

52.50 X 3 = $157.50

Answer:

right triangle it is because if u make a graph and put the points u would get a right isosclses triangle

Step-by-step explanation:

The triangle ABC with verticies A(3, 3), B(6, 9) and C(6, -3) is an isosceles triangle.

If a² + b² < c² then it is an acute angle triangle.

If a² + b² = c² then it is a right-angle triangle.

If a² + b² ≥ c² then it is an obtuse angle triangle.

Given, A ΔABC with verticies A(3, 3), B(6, 9) and C(6, -3).

We know the distance formula [tex]D = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2[/tex].

From this we find AB = √45 units, BC = 12 units and AC = √45 units.

Now, this is an isosceles triangle with two equal sides of √45 units.
