WILL GIVE BRAINLIEST!!! A rectangular field has an area of 4200 feet. Let the length of the field be (x+2) and the width be (x-3). Find the length and width of the field by writing a quadratic equation and solving using completing the square.

Answers

Equation: 2(x+2)(x-3)=4200
(x+2)(x-3)=4209

this is the equation because area is base x height. so those two sides being multiplied will give you 4209. so when you solve those two problems you will then multiply them and get 4209

Since we don't have the height of the prism we just need to find the area of the surface area

the area of the square is 16 cm^2

The area of the triangle is:

6 times 2 is 12 divided by 2 is 6

what is the value of k ?

Answers

Answer:

27-degrees

Step-by-step explanation:

these are vertical angles which are equal to each other *congruent

39 + k = 66 --> *subtract 39 from both sides*

k = 27

Answer:

27°

Step-by-step explanation:

Remember the angle opposite of another angle in two straight lines are equal

So 66=39+k

Then put k by itself by subtracting 39 from both sides

66-39=k

k=27°

Use the table to predict the number of times you will spin 3 when you spin the spinner 100 times.

Answers

Answer:

When you spin the spinner 100 times, you are likely to spin the number three 18 times.

Step-by-step explanation:

If the table shows the amount spun 50 times, then you would multiply 9 x 2 to get the answer, 18.

for 100 spins you are probably gonna spin (3) 18 times

Answer:

Hi there! The correct option is the third one, aka $176050.

Step-by-step explanation:

median is the value in middle

low from high:

168800

172200

174500

177600

183700

191400

174500 and 177600 is the middle.

174500 + 177600 = 352100

352100/2 = 176050

Suppose you have a bag with 25 letter tiles in it and 7 of the tiles are the letter V. If you pick a letter tile at random from the​ bag, the probability that it is the letter V is 7/25
. Suppose another bag has 500 letter tiles in it and 250 of the tiles are the letter V. Write the probability of picking a tile that is the letter V as a fraction and as a percent. From which bag are you more likely to pick a tile that is the letter V​?

Answers

answer:
the second bag has a probability of 1/2 or 50%.
step-by-step:
if you take 250/500, you divide 250 from 500 and get 2. therefore 250 is half of 500, leaving it as 1/2 or 50%.

The probability of picking a tile that is the letter V from the second bag is: As a fraction: 250/500 = 1/2 and As a percent: (1/2) x 100% = 50%.

What is probability?

Probability is a measure of the likelihood that an event will occur. It is a number between 0 and 1, with 0 indicating that the event is impossible and 1 indicating that it is certain. The closer the probability is to one, the more likely it is that the event will occur.

Probability can be used to make predictions and decisions in a variety of fields such as finance, statistics, and so on.

It is also an important concept in comprehending probability laws and the behaviour of random events.

The probability of picking a tile that is the letter V from the second bag is:

As a fraction: 250/500 = 1/2

As a percent: (1/2) x 100% = 50%

Thus, comparing the probabilities, the second bag is more likely to contain a tile with the letter V since the probability of picking a V from the second bag is higher (1/2 or 50%) than from the first bag (7/25 or 28%).
