☆ We know that angles of triangle opposite of its equal sides are also equal

Here the information that we know about the given triangle is

So the angles opposite to the equal sides will be equal .

→ So one of those equal angle is x so other will also be x .

☆ Interior angle sum property states that sum of interior angles of triangle will be 180°

→ 80° + x + x = 180°

→ 2x = 180°-80°

→ 2x = 100°

→ x = 100/2

→ x = 50° .

The value of x in the triangle is 50°.

We have,

The given triangle is an isosceles triangle.

This means,

There are two equal sides and the angles opposite to the equal sides are also equal.

Now,

The sum of the three angles in a triangle is 180.

So,

80 + x + x = 180

80 + 2x = 180

2x = 180 - 80

2x = 100

x = 100/2

x = 50°

Now,

We can cross cheked.

80 + 50 + 50

80 + 100

180

True.

Thus,

The value of x in the triangle is 50°.

Answer:

Bella's average velocity is approximately 0.61 m/s.

Step-by-step explanation:

To find velocity, we divide displacement (in this case, the same as the distance Bella traveled) by the time taken to travel this displacement.

Velocity = displacement/time

If we plug in the given values, we get:

Velocity = 2.5m/4.1s

Velocity = 0.6097561 m/s

Therefore, the correct answer is about 0.61 m/s.

Step-by-step explanation:

The vertex is (d, e)

for quadratic function: f(x) = ax² + bx + c  we have:

d = -b/a    and    d = (x₁ + x₂)/2  

a = 1,   b = k,   x₁ = -4,    x₂=-2      

so:

d = -b/a = -k/1 = -k   and   d = (x₁ + x₂)/2 = (-4-2)/2 = -3

Answer:

- 18x - 45

Step-by-step explanation:

=  12 (-2x + 3) - 3x + 9 (x - 9)

=  -24x + 36 - 3x + 9 (x - 9)

=  -24x + 36 - 3x + 9x - 81

=  - 18x - 45

Answer:

Step-by-step explanation:

First, distribute,

12(-2x+3)-3x+9(x-9)

-24x+36-3x+9x-81

Now combine like terms,

Therefore, the answer is -18x-45

The equation for the nth term of the arithmetic sequence is  -6n + 14 and the found 50 is -286.

An arithmetic sequence is a series of numbers that are ordered and share a common difference between each succeeding term. In the arithmetic sequence 3, 9, 15, 21, 27, for example, the common difference is 6.

Arithmetic is the branch of mathematics that studies numbers by performing various operations on them. A sequence is a numerically ordered list. The three dots indicate that the pattern should be continued. The difference is six.

a + d(n - 1)

a = 8 (first term)

d = -6 (common difference)

8 - 6(n - 1)

= 8 - 6n + 6

= -6n + 14

Find a 50:

-6(50) + 14

= -300 + 14

= -286

Therefore, the equation for the nth term of the arithmetic sequence is  -6n + 14.

25.4

The average time Janette to fold and put away all four items is 25.35 seconds. Then the correct option is C.

The mean of average is the ratio of the sum of observations and the number of observations.

Janette was timed by a store manager as she folded and stored a scarf, a shirt, a pair of trousers, and a jumper. Her time for the shirt was 26.1 seconds, the jumper 24.3 seconds, the trousers 32.8 seconds, and the scarf 18.2 seconds.

The average time Janette to fold and put away all four items will be given as,

Average = (26.1 + 24.3 + 32.8 + 18.2) / 4

Average = 101.4 / 4

Average = 25.35

The average time Janette to fold and put away all four items is 25.35 seconds. Then the correct option is C.

Answer:

Train P : [tex]t_{P} =\frac{330}{55}=6\ \text{hours}[/tex]

Train Q : [tex]t_{Q} =\frac{330}{55}+\frac{1}{2}=6\ \text{hours}\ 30\ \text{minutes}[/tex]

Step-by-step explanation:

The formula to compute the distance traveled by a train is:

[tex]d=s\times t[/tex]

Here,

d = distance traveled

s = speed of the train

t = time taken

From the provided information:

Train P :

d = 330 km

s = x km/h

Then time taken is:

[tex]t=\frac{d}{s}=\frac{330}{x}[/tex]

Train Q :

d = 330 km

s = (x - 5) km/h

[tex]t=\frac{330}{x}+\frac{1}{2}[/tex]

Both the trains traveled the same distance.

[tex]x\times \frac{330}{x}=(x-5)\times [\frac{330}{x}+\frac{1}{2}]\\\\330=\frac{330(x-5)}{x}+\frac{x-5}{2}\\\\330\times 2x=[660(x-5)+x(x-5)]\\\\660x=660x-3300+x^{2}-5x\\\\x^{2}-5x-3300=0\\\\x^{2}+60x-55x-3300=0\\\\x(x+60)-55(x+60)=0\\\\(x-55)(x+60)=0\\\\x=55[/tex]

Compute the time taken by the two trains as follows:

Train P : [tex]t_{P} =\frac{330}{55}=6\ \text{hours}[/tex]

Train Q : [tex]t_{Q} =\frac{330}{55}+\frac{1}{2}=6\ \text{hours}\ 30\ \text{minutes}[/tex]

( 3/2, 12) is the midpoint

Step-by-step explanation:

To find the x coordinate of the midpoint, add the x coordinates together and divide by 2

( -5+8)/2 = 3/2

To find the y coordinate of the midpoint, add the y coordinates together and divide by 2

( 3/2, 12) is the midpoint

Answer: The Athletic can other 12  volleyballs.

Step-by-step explanation:

If the director has $277 to spend then it means The director can spend at most $277.

Now one volleyball cost $22 and so we could represent the number of volleyballs you can buy by the expression 22x  and including the shipping fee,we will extend the expression to 22x + 13  Now since the Director can spend  up to $277 or less we can write the whole situation in a form of inequality as,

22x + 13 ≤ 277  Now solve for x to determine the number of volleyballs  

          -13   -13

22x  [tex]\leq[/tex] 264

x [tex]\leq[/tex] 12

Just count the number of zeros:

Step-by-step explanation:

There are 4 zeros, so the answer is 5 x 10^4.

Answer:

5 * 10^4

Step-by-step explanation:

In scientific notation, the amount an exponent has indicates how many zeroes are there.

Since we see four zeroes in the number 50,000

The only equation that would fit is of course 5 * 10^4

When completing the square, the goal is to create

a perfect square trinomial on the left side of the equation.

The number used to create one will come from

half the coefficient of the middle term squared.

In this case, that's half of 2 squared or 1 squared, which is 1.

So we add 1 to both sides giving us x² + 2x + 1 = 5.

From here, we set this as a binomial squared.

The first term is an x and the second term will

be half the coefficient of the middle term squared.

So we have (x + 1)² = 5.

Now square root both sides and remember to use plus or minus.

So we have x + 1 = ±√5.

Now subtract 1 form both sides to get x = -1 ± √5.

Answer:

lesser x =3

greater x =4

Step-by-step explanation:

f(x) = (x - 3)(2x - 8)

Set the function equal to zero to find the zeros

0  = (x - 3)(2x - 8)

Using the zero product property

0 = (x - 3)   0=2x - 8

Solve each  equation

3 = x          8 =2x

3=x            8/2 =x

                      4=x

lesser x =3

greater x =4
