Find the value of z in the triangle shown below.

Answers

Answer:

x = 68

Step-by-step explanation:

This is an isosceles triangle meaning that two sides of the triangle are equal in length while one side is not. Because we know that two of the side lengths are equal, we know that their corresponding angles are equal. In this instance, they both will have angles measuring 56°. We know that the sum of the angles of a triangle is equal to 180°. Use this information to set up an equation and solve for x.

x + 56 + 56 = 180

x + 112 = 180

x = 68

Which expression is a factor of 9x - 18x + 8. 3x - 4 3x, +4 3x +4, or 3x -8?

Answers

Answer: 3x-8

Step-by-step explanation:

The algebraic factor of the given quadratic equation 9x² - 18x + 8 is 3x - 4 thus option (A) is correct.

What is an algebraic factor?

An algebraic factor is the multiplication of two algebraic terms.

If we divide an algebraic factor by a factor that is available inside then the remainder after the division will be zero.

As per the given quadratic equation,

9x² - 18x + 8

⇒ 9x² - 12x - 6x + 8

⇒ 3x(3x - 4) - 2(3x - 4)

⇒(3x - 4)(3x - 2)

Hence "The algebraic factor of the given quadratic equation 9x² - 18x + 8 is 3x - 4".

At a meeting, 9 football players were there. If this is 30% of the football players, what is the total amount of football players on the team?

Answers

Answer: 30 player on the team

Step-by-step explanation:

If 9 players = 30% of the team then 3 = 10% of the team. With this information you can multiply 10 x 10 to get 100(%) and then multiply 3 x 10 to get 30(players). This may not be how you are supposed to solve this problem but oh well.

Write an equation that models this problem: Trevor paid$528 to stay at the MGM Grand Hotel in Las Vegas for four nights over New Year's weekend. What was the rate,r, per day to stay at the MGM Grand for New Year's?

Answers

Answer:

r = $105.6

Step-by-step explanation:

Given,

Amount paid by Trevor for 4 nights = $528

Rate per day = r

Now,

We know that a 4-night stay in the hotel means 5 days to stay at MGM Grand.

Now,

Amount paid = Number of days x Rate per day

$528 = 5 r

[tex]r = \frac{528}{5}[/tex]

r = $105.6

Hence, Trevor pays $105.6 to stay at the MGM Grand Hotel in Las Vegas for four nights.

Anna saved $30 each month from babysitting for 2.75 years. She spent 75% of her savings on a computer.
How much money did Anna have left?

Answers

Answer:

45.00 is what she has left

Step-by-step explanation:

Anna has $275.5 left after buying computer.

What is the percentage?

A percentage is a minimum number or ratio that is measured by a fraction of 100.

Given that Amount saved by Anna each month = $30

Time period = 2.75 years.

1 year = 12 months

2.75 years =  2.75 years x 12 = 33 months

The Amount saved in 33 months = 33 x 30 = $990

She spent 75% of her savings.

Amount spent = 75% of 990

Amount spent = 75% x 990

Amount spent = $742.5

Amount left = Savings - Amount spent

Amount left = 990- 742.5= $275.5

Hecne, Anna has $275.5 left after buying computer.

Peter is given the following equation. What operation should he use to solve for W?

Answers

Answer:

The correct answer is Option 1: multiplication

Step-by-step explanation:

Given equation is:

[tex]20 = \frac{w}{6}[/tex]

Given equation is a linear equation with one variable w. In order to solve the linear equations in one variable, properties of equality are used.

Solving for w means that w has to be isolated on one side of the equation i.e. w should be without a multiple or denominator.

The equation will be multiplied by 6 to remove the denominator in w/6

[tex]20*6 = \frac{w}{6} *6\\w = 120[/tex]

Hence,

The correct answer is Option 1: multiplication
