What is mean by Triangle?

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that;

LMN is a triangle shown in figure.

Now,

Here, LMN is a triangle shown in figure.

By definition of proportionality, we get;

⇒ x / 15 = (20 + x) / (15 + 18)

Solve for x as;

⇒ x / 15 = (20 + x) / 33

⇒ 33x = 15 (20 + x)

⇒ 33x = 300 + 15x

⇒ 33x - 15x = 300

⇒ 18x = 300

⇒ x = 300/18

⇒ x = 50/6

⇒ x = 16 2/3

Thus, The value of x will be 16 2/3.

A pitcher contains 1 3/4 quarts of milk. How many fluid ounces of milk does the pitcher contain ?

Answers

It contains 56 fl oz.

Final answer:

1 3/4 quarts is equivalent to 56 fluid ounces. This conversion is done by first converting the mixed fraction to an improper fraction, and then multiplying by 32, which is the number of ounces in one quart.

Explanation:

The subject of your question is Mathematics, specifically a unit conversion problem. You want to convert 1 3/4 quarts of milk to fluid ounces. We know that there are 32 fluid ounces in one quart. So, to convert quarts to fluid ounces, we multiply the number of quarts by 32:

For 1 3/4 quarts:

1. First, convert the mixed fraction to an improper fraction: (1 * 4) + 3 = 7/4 quarts

2. Multiply by 32(our conversion factor from quarts to fluid ounces): (7/4) * 32 = 56

So, 1 3/4 quarts is equal to 56 fluid ounces.

yesterday jamal scored -20 points on a puzzle today he scored more points use absolute value to describe today's score as a loss

Answers

Absolute value is never negative so the answer is 20

Final answer:

The absolute value of Jamal's score is 20, indicating a loss of 20 points.

Explanation:

In math, the absolute value of a number is the positive value of that number, regardless of its sign. Since Jamal's score on the puzzle was -20 points, we can use absolute value to describe today's score as a loss by taking the absolute value of the score. The absolute value of -20 is 20, which means that today's score was a loss of 20 points.

Hello.

A scale factor is a term that defines the multiplicative/divisive measurement difference between the two same shapes. The way we can find our scale factor is by dividing our new measurement by the old measurement.

681 / 3 = 227

Our scale factor is 1/227, as 3 is 1/227 of 681 - and we are looking for the scale factor to find what multiplied by 681 would give us 3.

A circuit board manufacturer can produce 2,000 boards per hour. How many days will it take to produce 16,500 if the company has a 10 hour work shift? How many days will it take to produce 16,500?

Answers

Hi Mrsdiaz1jd1977owwfvt!
OK so 2,000 boards per hour in 10 hours is 2,000*10=20,000 boards in 10 hours. So it can produce 16,500 boards in less than a day.
I may be wrong but I hope this helps!

Answer:

it will take less than one day.

Step-by-step explanation:

A circuit board manufacturer can produce 2,000 boards per hour.

If the company has a 10 hour work shift.

manufacturer can produce in one day = 2000 × 10 = 20,000

To produce 16,500 boards, they need time = 16,500 ÷ 2000 = 8.25 hours

The company will take to produce 16,500 boards in 8.25 hours less than one day.

so 1/3 of 6 cardinals is 2 cardinals

There are 20 cardinals, how many mockingbirds.
the ratio is 2/3, so 20/30 is your answer
