Answer:

One of the angles in the triangle might be 50.

AND

The length of the third side must be 11cm or smaller.

Step-by-step explanation:

-The triangle might be an equilateral triangle (having all the same sides and angles). False, since the triangle sum theorem states that all angles inside of a triangle must add up to 180, so an equilateral triangle would need to have all three angles at 60 degrees.

-One of the angles in the triangle must be 120 (false; it can be anything above 90, which is not only 120)

-The length of the third side must be 11cm or smaller. (True, Triangle Inequality Theorem)

-One of the angles in the triangle might be 50 (possibly, so very much true)

Answer:

1/4

Step-by-step explanation:

you add 3/5 to the other side and find the lcm making it 6/10--1/10=5/10. Then 5/10 divided by 2 = 2.5/10 which you can simplify to 1/4.

Answer: x=1/4

Step-by-step explanation:

1. Isolate x: if you move -3/5 to the other side, your equation would become

=> 2x=-1/10+3/5

2. Find the common denominator: since you can't add -1/10 with 3/5 without simplifying, you're equation would change to this:

=> 2x=-1/10+6/10

3. Simplify:

=> 2x=5/10  =>  2x=1/2

4. Divide:

=> 2x=1/2  =>  x=1/2*1/2  =>  x=1/4

Answer:

[tex]2a - b -c[/tex]

Step-by-step explanation: We know that:

[tex]log_{2} 5 = a\\log_{2} 3 = b\\log_2 7 = c\\[/tex]

and we want:

[tex]log_2 \frac{25}{21}[/tex].

We can form the numerator using just the first fact (since 5^2 is 25) and the denominator using the latter two (since 3*7 = 21).

[tex]log_2 \frac{25}{21} = log_2 \frac{5^2}{3*7}.[/tex]

The logarithm of a division can be expanded by subtracting the numerator and denominator (while still keeping the log). The logarithm of a product can be expanded by adding the terms while keeping the log. If the logarithm is raised to a power, we can bring it down as a factor:

[tex]log_2 \frac{5^2}{3*7} = log_2(5)^2 - log_2 (3*7) = 2 log_2(5) - (log_2 3 + log_2 7)[/tex]

[tex]= 2 log_2(5) - log_2 3 - log_2 7[/tex] .

Substituting the variables:

[tex]2 log_2(5) - log_2 3 - log_2 7 = 2a - b - c[/tex]

Answer:

15.12

Step-by-step explanation:

8% of 14 = 1.12

Answer:

$551.25

Step-by-step explanation:

1. Encuentre el 25% de $735:

0.25 x 735 = 183.75

2. Reste este número del precio original, $735:

735 - 183.75 = 551.25

The lady paid $551.25 after the 25% discount on merchandise.

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

We have a 25% discount is advertised on all merchandise. A lady bought a merchandise for $735.

Assume that she paid $x after the 25% discount. Then, we can write -

[x] = 735 - 25% of 735

[x] = 735 - (25/100) x 735

[x] = 735 - (1/4) x 735

[x] = 735(1 - 1/4)

[x] = 735 x 3/4

[x] = 551.25

Therefore, the lady paid $551.25 after the 25% discount on merchandise.

Answer:

110º

Step-by-step explanation:

Because the angle starts at 10º, and ends at 120º, so if we moved the angle down to start at 0º we would have to subtract 10º, so we must subtract 10º from 120º. You end up with 110º.

Hope this helps! Have a great day!

Answer:

You are a Quadrilateral.

Step-by-step explanation:

The four sided shape that has four right angles and the whole sides are not equal to each other is a rectangle.

A rectangle is a quadrilateral. This simply means it has four sides.

The sides of a rectangle are not equal.

Therefore, the four sided shape that has four right angles and the whole sides are not equal to each other is a rectangle.

Answer:

f(k) = 2*k + 1

Step-by-step explanation:

The 'f' function takes the variable, doubles it, and then adds 1.

So f(k) = 2*k + 1

f(g) = 2*g + 1

f(m) = 2*m + 1, and so on

It doesn't really matter which variable you use, the function still does the same thing to it.

Answer:-9 :)

Step-by-step explanation:

Answer:

B. The Y-intercept of Function A is less than the Y-intercept of Function B

F. The rate of change of Function A is greater than the rate of change of Function B

Step-by-step explanation:

Function A rate of change and y-intercept:

✔️Rate of change using two pairs of values from the given table, (1, 2) and (3, 10):

Rate of change = ∆y/∆x = (10 - 2) / (3 - 1) = 8/2 = 4

Rate of change (m) of Function A = 4

✔️ To find the y-intercept (b) of function A, substitute (x, y) = (1, 2) and m = 4 into y = mx + b (slope-intercept form):

2 = 4(1) + b

2 = 4 + b

2 - 4 = b

-2 = b

b = -2

Y-intercept (b) of function A = -2

Function B rate of change (m) and y-intercept (b):

The function, y = 3x + 4 is given in the slope-intercept form, y = mx + b.

Therefore,

Rate of change/slope (m) = 3

Y-intercept (b) = 4

The following staments about the properties of both functions are therefore true:

B. The Y-intercept of Function A is less than the Y-intercept of Function B

F. The rate of change of Function A is greater than the rate of change of Function B

Answer:

c = 29

Step-by-step explanation:

Law of sines is given as: [tex] \frac{a}{sin(A)} = \frac{b}{sin(B)} = \frac{c}{sin(C)} [/tex]

B = 180 - (57 + 44) = 79°

b = 41

C = 44°

c = ?

Thus:

[tex] \frac{b}{sin(B)} = \frac{c}{sin(C)} [/tex]

Substitute

[tex] \frac{41}{sin(79)} = \frac{c}{sin(44)} [/tex]

Multiply both sides by sin 44

[tex] \frac{41}{sin(79)}*sin(44) = \frac{c}{sin(44)}*sin(44) [/tex]

[tex] \frac{41*sin(44)}{sin(79)}*sin(44) = c [/tex]

c = 29.0140633 ≈ 29
