I think its 21, because the BD line divides the big triangle into 2 ones and they are equilateral triangle, sorry if I'm wrong

Answer 2

Answer:

BD = 21

Step-by-step explanation:

The sector divided AC into two equal pieces and since this is a right triangle the height of the triangle BD is equal to half of the base

(21+21) / 2 = x

42 / 2 = x

21 = x

Both equations are equal because 1/2 and 3/6 are equivalent fractions. By multiplying both the numerator and denominator of 1/2 by 3 (3/3=1) we can get 3/6 making both equations appear the same

Answers

Answer:

Surface area of cuboid = 78 unit²

Step-by-step explanation:

Given diagram is a cuboid prism

Given:

Length of cuboid = 5 unit

Width of cuboid = 3 unit

Height of cuboid = 3 unit

Find:

Surface area of cuboid

Computation:

Surface area of cuboid = 2[lb + bh + hl]

Surface area of cuboid = 2[(5)(3) + (3)(3) + (3)(5)]

Surface area of cuboid = 2[15 + 9 + 15]

Surface area of cuboid = 2[39]

Surface area of cuboid = 78 unit²

What percentage of Americans would you predict wear glasses?

Answers

Answer: 64%

75% of adults use some sort of vision correction. About 64% of them wear eyeglasses, and about 11% wear contact lenses, either exclusively, or with glasses. Over half of all women and about 42% of men wear glasses.

63.8% of Americans are predicted to wear glasses

How to determine the percentage?

The given parameters are:

Glasses = 638Sample size = 1000

The percentage of Americans that wear glasses is calculated as:

Percentage = Glasses/Sample size

This gives

Percentage = 638/1000

Evaluate the quotient

Percentage = 0.638

Express as percentage

Percentage = 63.8%

Hence, 63.8% of Americans would wear glasses

Answer:

Step-by-step explanation:

No. of people going to beach = 46 .

Using Unitary Method ,

9 people can go in one van .

1 person can go in 1/9

46 people can go in 1/9 * 46 = 5.1

Since vans can't be in fraction , 1 extra van for 1 person is need that is for 46th person .

So total number of vans = 5 + 1 = 6

Which shows a correct comparison? A: 5 milliliters > 50 liters B: 2 liters < 200 milliliters C: 100 liters < 1,000 milliliteres D: 3,200 milliliters > 3 liters

Answers

Answer:

Step-by-step explanation:

Note that

> means greater than

< means less than

for example : 2 < 3 means 2 is less than 3

3 >2 means 3 is greater than 2

To determine which comparison is better we have to convert litre to millimetre

1 litre = 1000mm

A 5 mm > (50 x 1000)

5 mm > 50,000

5 is not greater than 50,000

B. (2 x 1000) < 200 mm

2000 < 200

2000 is not less than 200

C. (100 x 1000) < 1,000

100,000 < 1000

100,000 is not less than 1000

D. 3200 > (3 X 1000)

3200 > 3000

3200 is greater than 3000

Answers

the average can be calculated by adding the scores together and then dividing by the number of scores.

we can set up an equation:

let x = test score needed on next test

(72+72+80+x)/4 = 71

multiply both sides by 4

72+72+80+x = 284

add like terms

224+x=284

subtract 224 from both sides

x=60

she will need a 60 for her average to be 71

She needs to score a 60 to have a average score of 71,

72+72+80+60=284

284/4=71

A small business owner is determining her profit for one month. Her expenses were $230.21 for utilities, $2,679.82 for rent, and $3,975.00 for employee salaries. She made $11,449.27 in sales for the month. What is her profit?

Answers

She made 9,604.21 sorry if I’m wrong I really tried

Her profit would amount to $4564.24 for one month which is determined by subtracting her total expenses from made revenue.

What are Arithmetic operations?

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.

- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.

for example 12 -2 = 10

For the month, she made a revenue of $11,449.27.

To calculate her profit, we have to subtract her total expenses from made revenue.

Her expenses were $230.21 for utilities, $2,679.82 for rent, and $3,975.00 for employee salaries which are given in the question.

Total expenses = 230.21 + 2,679.82 + 3,975.00 = 6885.03

As per the given data, the solution would be:

⇒ Total revenue - Total expenses

⇒ 11,449.27 - 11,449.27

Apply the subtraction operation, and we get

⇒ 4564.24

Therefore, her profit would amount to $4564.24 for one month.

A new online music service has a collection of 1,500 songs. It expects to triple the number of songs each year for the next few years. Write an equation representing the relationship, where x is time in years, and y is the number of songs available.

Answers

Answer: y = (3^(x-1))*1500

Step-by-step explanation:

We want the relationship

y = f(x)

where y is the number of songs, and x is the number of years.

We know that in the first year, x = 1, the site has 1,500 songs.

The next year, x = 2, the number of songs is tripled, then we will have:

1,500*3 = 4500 songs.

The next year, x = 3, we will have: 3*(3*1500) = (3^2)*1500.

when x = 4, the number is tripled again:

3*(3^2)*1500 = (3^3)*1500

We already can see the pattern, for the year x, the site will have:

y = (3^(x-1))*1500 songs.

This is the equation we are looking for.

Answers

Answer:

See below.

Step-by-step explanation:

y^2 - 6y + 9 can be changed correctly into y^2 - 2(y)(3) + 3^2.

Up to here, it's correct.

The right side above shows a polynomial that is the square of a binomial.

It factors into (y - 3)^2.

The correct factorization is (y - 3)^2.

The incorrect factorization of the student's solution is the product of a sum and difference.

The product of a sum and a difference is the correct factorization for a difference of squares.

For example, y^2 - 9 is the same as y^2 - 3^2 and is a difference of squares.

It factors into (y + 3)(y - 3), a product of a sum and a difference.
