Answer 18, 19, and 20

Answer:

810 feet.

Step-by-step explanation:

We are supposed to find the final altitude of the helicopter.

We have been given that a helicopter is flying at a altitude of 785 feet, this means that altitude of helicopter is positive.

Further, the helicopter descends 570 feet, this means that altitude of helicopter is [tex]-570[/tex].

Finally, the helicopter ascends 595 feet, this means that altitude of helicopter is [tex]595[/tex].

[tex]\text{Helicopter's final elevation}=785\text{ ft}-570\text{ ft}+595\text{ ft}[/tex]

[tex]\text{Helicopter's final elevation}=810\text{ ft}[/tex]

Therefore, the final elevation of helicopter is 810 feet.

The net change in the value of the account, when rounded to the nearest dollar, is $550.

To find the net change in the value of the account, you would sum up the amounts deposited, subtract the amounts withdrawn, and add the interest earned:

Net change = (Deposits - Withdrawals) + Interest earne

Net change = ($500 - $250) + $300

            = $250 + $300

            = $550

Therefore, the net change in the value of the account, when rounded to the nearest dollar, is $550.

The probable question maybe:

"What is the net change in the value of an investment account after depositing $500, withdrawing $250, and earning $300 in interest, when rounded to the nearest dollar?"

Answer:

There are 15 boxes of 10 oz boxes

Step-by-step explanation:

Let the number of boxes of 10 oz = x

and let the number of boxes of 16 oz = y

By the statement

"Total number of boxes sold is 24"

Equation for the statement will be

x + y =24 ---------------(1)

By the  statement

"she collected $97.50 while rate of 10 oz box is $3.50 and rate of 16 oz box is $5.00."

Equation for the statement will be

1.5x + 5y = $97.50 ------------(2)

From equation (1) we put the value of y = 24 - x in equation (2)

1.5x + 5(24 - x) =  97.50

1.5x + 120 - 5x = 97.50

-3.5x = 97.50 - 120

3.5x = 22.50

x = [tex]\frac{22.5}{1.5}[/tex]

x = 15

Therefore, number of 10 oz boxes is 15.

The number must be added to [tex]2\frac{3}{8}[/tex] to make 6 is [tex]3\frac{5}{8}[/tex].

We need to find what we need to add to [tex]2\frac{3}{8}[/tex] to make 6.

In Mathematics, fractions are represented as a numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.

The fraction [tex]2\frac{3}{8}[/tex] can be written as 19/8

Let x be the number added to given fraction, that is

19/8 +x=6

⇒ x=6-19/8

⇒ x= (48-19)/8

⇒ x= 29/8

⇒ x= [tex]3\frac{5}{8}[/tex]

Hence, the number must be added to [tex]2\frac{3}{8}[/tex] to make 6 is [tex]3\frac{5}{8}[/tex].

The expression representing Rose's stamp collection is given by R = (1/2)x - 7. It denotes that Rose's collection is 7 less than half of Van's stamp collection, where x represents the total number of stamps in Van's collection.

Let's denote Van's stamp collection as x. According to the given information, Rose's stamp collection is 7 less than half of Van's stamp collection.

Expression for Rose's stamp collection (R):

R = (1/2)x - 7

Here's the breakdown of the expression:

(1/2)x represents half of Van's stamp collection.

-7 signifies 7 less than half of Van's stamp collection.

This expression encapsulates the relationship between Rose's stamp collection and half of Van's collection, diminished by 7.

Answer:

Cost:$ 920 each or $5,520

Total annual interest: $65 per bond and $390 total

Yield: 7.06%

Step-by-step explanation:

The cost of the bonds is given by the multiplication of the value of the bonds by 92 and divided by 100:

1000*92/100=920

So the cost of each bond would be $920

Then the interest that is payed by the bonds is based on its value which is $1000, so he receives 65 dollars per bond a year, that multiplied by the 6 bonds is equal to $390.

The yield is the real money paid to return interest rate relation, so you just have to take the percentage if 5,520 is the 100, how much is $390=

5520/100=390/x

x=39000/5520=7.06%

The simplified form of [tex]\frac{6}{18}[/tex] is [tex]\frac{1}{3}[/tex].

The equivalent fraction of 8/9 with the denominator 18 is 16/18.

To write the fraction 8/9 as an equivalent fraction with the given denominator 18, we have to find a number that we multiply by 9 (the original denominator) to get 18. This number, in this case, is 2. What we do to the bottom of a fraction, we should also do to the top, therefore we would also multiply the numerator (8) by the same number (2). So, the equivalent fraction is 8 * 2 / 9 * 2 = 16 / 18.
