Which best describes the relationship between the two triangles below

32×.25=8

so 8 students wear glasses

A. 12 in

We know that the sports stadium is 180 ft tall and that in the scale model there is 2 in for every 30 ft. If we divide 180 by 30 we get 6. There is 2 in for every 30 ft, so the answer would be 6 x 2 or 12 in.

Unit rate is the quantity of an amount of something at a rate of one of another quantity.

If 2 inches = 30 feet and the height of the sports stadium is 180 feet.

The height of the sports stadium in scale model in inches is 12 inches.

Option C is the correct answer.

It is the quantity of an amount of something at a rate of one of another quantity.

In 2 hours, a man can walk for 6 miles

In 1 hour, a man will walk for 3 miles.

In 5 minutes a machine can cut 10 potato

In 1 minute a machine can cut 2 potato.

We have,

30 feet = 2 inches

Divide both sides by 30.

1 feet = 2/30 inches

Now,

1 feet = 2/30 inches

Multiply 180 on both sides.

180 feet = 180 x 2/30 inches

180 feet = 6 x 2 inches

180 feet = 12 inches

Thus,

If 2 inches = 30 feet and the height of the sports stadium is 180 feet.

The height of the sports stadium in scale model in inches is 12 inches.

Answer:

yes theoretically it did work

Step-by-step explanation:

hypothetically it is supposed to land on each side half of the time, but as we all know it's a matter of luck. since after you put on the layer of coating and it landed on heads more thank half of the time (50%), it technically has worked but in a real world application it would be hard to tell/justify.

Final answer:

To find the solutions of the quadratic equation 3x^2 - x + 6 = 0, we can use the quadratic formula. The solutions are complex numbers: x = (1 ± i√71) / 6.

Explanation:

To find the solutions of the quadratic equation 3x^2 - x + 6 = 0, we can use the quadratic formula. The quadratic formula is given by:

x = (-b ± √(b^2 - 4ac)) / (2a)

By comparing the given equation to the standard quadratic equation form ax^2 + bx + c = 0, we can determine that a = 3, b = -1, and c = 6. Substituting these values into the quadratic formula, we get:

x = (-(-1) ± √((-1)^2 - 4(3)(6))) / (2(3))

Simplifying further, we have:
x = (1 ± √(1 - 72)) / 6

Finally, evaluating the expression under the square root, we get:
x = (1 ± √(-71)) / 6

Since the square root of a negative number is not a real number, the solutions to the quadratic equation are complex numbers. Hence, the solutions are:

x = (1 ± i√71) / 6

Answer:

y = x² + 3x - 40

Step-by-step explanation:

Given the zeros are x = - 8 and x = 5, then the factors are

(x + 8) and (x - 5) and

y = (x + 8)(x - 5) ← expand factors

y = x² - 5x + 8x - 40, hence

y = x² + 3x - 40 ← in standard form

Answer:a

Step-by-step explanation:

it just looks like it

Answer:

y = 1, x = 2/5 or (2/5, 1)

Step-by-step explanation:

Since you already know that y = 1, you can substitute 1 into the y of the other equation. So you end up with:

1 = -5x + 3

Then you solve this equation. First you subtract 3 from both sides and get:

-2 = -5x

Then you divide both sides by -5 and get:

2/5 = x

And you already know that y = 1 so your answer is:

x = 2/5, y = 1 or (2/5, 1)

Answer:

The answer is 9

Step-by-step explanation:

39X39 is 1521

1521/169=9

so carmen needs 9 cans of paint

To paint the square ceiling of 1521 square feet, Carmen will need to round up from the approximately 9 cans of paint that would be required to cover it, so she will need to purchase 10 cans of paint.

Carmen would be dealing with a mathematical concept related to area and division. Since the ceiling is a square, we can find the total area by squaring the length of one side. This means multiplying 39 (feet) by itself: 39*39 = 1521 square feet.

Each tin of paint can cover 169 square feet, so if we divide the total square feet of the ceiling by what one tin can cover, we get the amount of tins needed. This means 1521 divided by 169: approximately 9 cans of paint. Since you cannot buy a fraction of a can, Carmen will need to purchase 10 cans of paint to ensure she can cover the entire area of the ceiling.

Answer:

[tex]P = 84\%[/tex]

Step-by-step explanation:

The average is:

[tex]\mu = 40,000\ miles[/tex]

The standard deviation is:

[tex]\sigma = 1,000\ miles[/tex]

We want the probability that a tire lasts more than 39,000 miles.

This is:

[tex]P (X>39,000)[/tex]

Now we must transform these values to those of a standard normal distribution to facilitate calculation by using the probability tables.

[tex]P (X> 39,000)\\\\P (X-\mu> 39,000-40,000)\\\\P (\frac{X-\mu}{\sigma}> \frac{39,000 -40,000}{1,000})\\\\P (Z> -1)[/tex]

This is:

[tex]P(Z> -1) = P(Z<1)[/tex] ---------- (For the symmetry of the standard normal distribution)

When you search for the normal standard table, you get the following value:

[tex]P(Z <1) = 0.8413\\\\P(Z> -1) = 0.8413[/tex]

the factored form is

-25xy(-4z+3)

To find the total number of chairs Gina set up in the past two weeks, we need to add the number of chairs she set up last week to the number of chairs she set up this week.

Answer:

C. O.5s

Step-by-step explanation:

If the wave length is 100m and it goes at a speed of 200m/s then it will only take 0.5 seconds because 100 is half of the speed of 200

Answer:

C

Step-by-step explanation:

The formula we use to solve this would be:  [tex]T=\frac{\lambda}{v}[/tex]

Where

T is the period in seconds

[tex]\lambda[/tex] is the wavelength in m, and

v is the speed of the wave in m/s

We have [tex]\lambda[/tex] equal to 100, and v = 200 m/s. Plugging these into the equation, we get the period:

[tex]T=\frac{\lambda}{v}\\T=\frac{100}{200}\\T=0.5[/tex]

C is the right answer.
