factor -7v^2-25v-12 show steps

Answer:

the correct answer is 0.38, I used the other persons answer and got it wrong.

Step-by-step explanation:

A Dime is worth 2 nickels which equals 10.

let no of dimes be x

let no of nickles be y

so as per the data mentioned in the question , x=2*y-10

total amount = $2.75 

so total amount should comprise of nickels and dimes

x*dimes + y*nickels = $2.75

x*( 2 nickels)+ y *nickels = $2.75

=> nickles( 2x+y) = $ 2.75

but 20 nickels = 1 dollar

nickles(2x+y) = 2.75*20 nickels

cancelling nickles on both sides

2x+y = 55

already we know that x= 2y-10 

so 2(2y-10) +y= 55

4y-20+y=55

5y -20 =55

So, your answer is 55.

Answer:  15 nickels and 20 dimes

Step-by-step explanation:

Nickels (N) = N and each is worth $0.05

Dimes (D) = 2N - 10 and each is worth $0.10

0.05N + 0.10D = 2.75

0.05N + 0.10(2N - 10) = 2.75

0.05N + 0.20N - 1.00 = 2.75

             0.25N - 1.00 = 2.75

             0.25N           = 3.75

                    N          =   15

D = 2N - 10

   = 2(15) - 10

   =  30  - 10

   =     20

Check:

0.05(55) + 0.10(20) = 2.75

   0.75    +     2.00   = 2.75

            2.75           = 2.75 [tex]\checkmark[/tex]

Answer:

100

Step-by-step explanation:

.75 will make 99 closer to 100

The rounded-off 99.75 to the nearest whole number will be 100.

To round up or down of tens place then we need to look at the unit place if it is less than 5 then we need to round down and if it is greater than 5 then we need to round up of tens digit.

In order to round to a hundred, we need to look at the tens digit if it is less than 5 then we round down and if it is 5 or greater than 5 then we will round up.

The whole number is the nondecimal number for example 2,5,7.

Given the number 99.75

The whole number around 99.75 are 99 and 100

Now,

100 - 99.75 = 0.25 and 99.75 - 99 = 0.75

Since 0.25 < 0.75

100 will be nearer to 99.75 so it will be the correct answer.

Hence "The rounded-off 99.75 to the nearest whole number will be 100".

35 is the answer for this question hope it helps

To find the quotient of 100 and the sum of b and 24, divide 100 by the sum of b and 24.

The quotient of 100 and the sum of b and 24 can be found by dividing 100 by the sum of b and 24. This can be expressed as:

Quotient = 100 / (b + 24)

For example, if b is 5, the sum of b and 24 is 29. So, the quotient of 100 and 29 would be approximately 3.4483.

Answer:

9.6

Step-by-step explanation:

✯Hello✯

↪  so first we need to 'kill' the smaller x. This can be done by taking 2x from 7x

↪  That leaves us with 18= 5x-30. Add 30 on both sides and we get 48=5x

↪  we divide by 5 on both sides

↪  that gives us 9.6

HOPE THIS HELPS

❤Gianna❤

To solve the equation 2x+18=7x-30, subtract 2x from both sides, add 30 to both sides, and divide both sides by 5 to find x = 9.

To solve the equation 2x+18=7x-30, we need to isolate the variable x on one side of the equation. First, we can start by simplifying both sides of the equation. Subtracting 2x from both sides gives us 18 = 5x - 30. Next, we can add 30 to both sides to get rid of the -30 on the right side. This gives us 48 = 5x. Finally, divide both sides by 5 to solve for x. The final solution is x = 9.

Answer:

Step-by-step explanation:

Final answer:

To convert the ratio of 20 ounces to 2 pounds into the simplest form, multiply 2 pounds by the conversion factor of 16 to equal 32 ounces. The fraction 20/32 is then simplified to 5/8, which is the simplest form of the ratio.

Explanation:

To convert the ratio of 20 ounces to 2 pounds into a fraction in simplest form, you must first know the unit equivalence between pounds and ounces, which is 1 pound = 16 ounces. Since we are converting pounds to ounces, we multiply the number of pounds by 16. Therefore, 2 pounds is equivalent to 2 x 16 = 32 ounces. Now, we have a ratio of 20 ounces to 32 ounces, which can be expressed as a fraction 20/32. To simplify, both numbers can be divided by the greatest common divisor (GCD) of 4, resulting in 5/8. Thus, the ratio of 20 ounces to 2 pounds in the simplest form is 5/8.

Anaya’s Team won 20 games

Anaya's team won 5 out of every 7 games. Using the proportion principle, we find that the team won 20 out of 28 games in the season.

Anaya's team won 5 of every 7 games played. This means, for every 7 games, they won 5 games, which is their win ratio. To find out how many games they won out of the 28 games played in the season, we can set up a proportion and solve it.

Step 1: Setup the proportion: 5/7 = x/28, where x is the number of games won.

Step 2: Solve the proportion for x. Cross-multiply and divide: (5*28)/7 which gives us 20.

So, Anaya's team won 20 games during the season out of the 28 games they played.

They don't have a year to pay it back. They have four months so you just use that as time.

Write the equation

A = 15,000 x (1 + 0.086 x 4)

( ) first.

0.086 x 4 = 0.344

rewrite.

A = 15,000 x (1 + 0.344)

( ) again.

1 + 0.344 = 1.344

rewrite

15,000 x 1.344 = 20,160

The student made a calculation error in converting 4 months into a year fraction. It should be 0.333..., not 0.33. With the correct conversion, the maturity value can be accurately calculated using the formula A=P(1+RT).

From the details that you've given, the student used the formula A=P(1+RT) correctly, where A is the maturity value of the loan, P stands for the principal amount, R for the rate of interest, and T for time.

In this question, P = $15000, R = 8.6%, and T = 4 months. The student correctly changed 8.6% to 0.086 (since percentage must be converted to decimal form by dividing by 100 in calculations) and also accurately converted 4 months into 0.33 (since the term of the loan is expressed in terms of a year).

However, the correct conversion of 4 months into year should be 4/12 = 0.333.... (since 1 year is equal to 12 months), not 0.33. So T = 0.333...

Let's plug in these values:
A = 15000(1+0.086*0.333...)
This will give you the accurate maturity value.

Price of the printer is = $193.20

Step-by-step explanation:

Office supply store purchased an all in one printer wit a regular price = $240

After 15% off price of the printer = $240 - 15% of $240

                                                     = [tex]240-\frac{15\times 240}{100}[/tex]

                                                     = 240 - 36

                                                     = $204

The store is offering $20 mail in rebate so the price of printer after rebate

= $204 - $20

= $184

Now price of the printer including sales tax = 184 + 5% of 184

= 184 + [tex]\frac{5\times 184}{100}[/tex]

Answer:

6, she can buy 6 oranges.

After purchasing 5 apples, Lynne has $4.75 left. Since oranges cost $0.75 each, she can afford to buy a maximum of 6 whole oranges.

The subject of this question is a real-world application of the basic mathematics principle of subtraction and division.

Lynne starts with $8.00 and spends $0.65 per apple for 5 apples, which totals to $3.25. We subtract that sum from the starting amount. $8.00 - $3.25 = $4.75 remains. This remaining money is what Lynne can use to buy oranges, which cost $0.75 each.

To find out the maximum whole number of oranges she can buy, we divide the remaining money by the cost of each orange: $4.75 / $0.75 ≈ 6.33.

Since Lynne can't buy a fraction of an orange, we round down to the nearest whole number. So, Lynne can buy a maximum of 6 oranges.
