Answer:

$7.10

Step-by-step explanation:

1 bar = $1.29

10 bars = 10 x $1.29 = $12.90

Change received = $20 - $12.90 = $7.10

Answer:

7.1

Step-by-step explanation:

1 twix bar = $1.29

10 twix bar = $12.9

change = 20 - 12.9

= $7.1

  G 6.231 and 6.233

Step-by-step explanation:

F 6.232 and 6.236 rounds to 6.23, 6.24

G 6.231 and 6.233 rounds to 6.23, 6.23

H 6.229 and 6.239 rounds to 6.23, 6.24

J 6.222 and 6.238 rounds to 6.22, 6.24

_____

One way to determine the rounded value is to add 0.005 to the number, then drop all digits to the right of the hundredths place.

Examples:

  6.222 +0.005 = 6.227 ⇒ 6.22

  6.238 +0.005 = 6.243 ⇒ 6.24

Sales tax and tip will increase the price of an item.

The cost of each meal is: $10.89

Let the cost of both meals be x.

A 20% tip means that, the current price is:

[tex]Price = x \times (1 + 20\%)[/tex]

A 6% sales tax on the meal means that, the current price is:

[tex]Price = x \times (1 + 20\%) \times (1 + 6\%)[/tex]

So, we have:

[tex]Price = x \times (1 + 0.20) \times (1 + 0.06)[/tex]

[tex]Price = x \times (1.20) \times (1.06)[/tex]

[tex]Price = x \times 1.272[/tex]

The amount paid is $27.72

So, the equation becomes

[tex]27.72= x \times 1.272[/tex]

Make x the subject

[tex]x = \frac{27.72}{1.272}[/tex]

[tex]x = 21.78[/tex]

So, the cost of each meal is:

[tex]Each= \frac{21.78}{2}[/tex]

[tex]Each= 10.89[/tex]

Hence, the cost of each meal is: $10.89

Step-by-step explanation:

the formula to find the x values to deliver y=0 results of a squared equation is

x = (-b ± sqrt(b² - 4ac))/(2a)

a, b, c are the constant factors in the 3 terms of a squared equation.

here in our example of 2x² - x - 10

a = 2

b = -1

c = -10

x = (1 ± sqrt(1² - 4×2×-10))/(2×2) =

= (1 ± sqrt(1 + 80))/4 = (1 ± sqrt(81))/4 =

= (1 ± 9)/4

x1 = (1 + 9)/4 = 10/4 = 2 2/4 = 2 1/2 = 2.5

x2 = (1 - 9)/4 = -8/4 = -2

The function of this equation is: [tex]F(n)=\frac{1}{4}n^4-\frac{1}{3}n^3+n+C[/tex]

Step-by-step explanation:

Answer:

1, 5, 19, 49

Step-by-step explanation:

To obtain the first 4 terms substitute n = 1, 2, 3, 4 into f(n)

f(1) = 1³ - 1² + 1 = 1 - 1 + 1 = 1

f(2) = 2³ - 2² + 1 = 8 - 4 + 1 = 4 + 1 = 5

f(3) = 3³ - 3² + 1 = 27 - 9 + 1 = 18 + 1 = 19

f(4) = 4³ - 4² + 1 = 64 - 16 + 1 = 48 + 1 = 49

The first 4 terms are 1, 5, 19, 49

Answer:

Step-by-step explanation:

in the problem it says she plans to do thirty pages so lets let 30 be our y value so ?x +30 and she plans to increase by 5 each day key word is each which means multiply so let 5 be our x value which will give you the equation 500=5x+30 so step by step here we go

                                                500=5x+30

1. 500=5x+30

500 −30= 5

Step-by-step explanation:

We actually don't need to know all of the restrictions.

We know that a vertical stretch factor of 4 means multiplying a square root function by [tex]4[/tex]. So, the answer will be in the form [tex]y=4\sqrt{x+c}+k[/tex], where c and k are real numbers.

Aha! Only one of these conditions satisfy the restrictions, so we have that [tex]\boxed{y=4\sqrt{x+3}+7}[/tex] has to be the answer.

The equation which relates speed, V and time, t to the total distance traveled is 70 = Vt

Since he is traveling at a constant speed, the relationship between, V and t can be written thus :

At time, t = 5

At time, t = 7

At time, t = 3.5

Therefore, the relationship between V and t with distance is 70 = Vt

so 32.14 is breakable. first break it up by the tens place you have 3 tens.

next the ones place you have 2 ones

then the tenths place you have 1 tenth

then the hundredth place you have 4 hundreths

so the 3 tens is equal to 30

the 2 ones is equal to 2

the 1 tenth is equal to 0.1

the 4 hundredth is equal to 0.04

Answer:

25/15 > 24/18

Step-by-step explanation: Both of these fractions can be reduced so that the denominator is 3. This will make it much easier to compare the two fractions. For 24/18, if you divide both the numerator and the denominator by 6, then the fraction simplifies to 4/3. For 25/15, if you divide the numerator and denominator by 5, then the fraction simplifies to 5/3. Since these fractions have a common denominator, the fraction with the larger numerator is going to be the larger fraction. So, 25/15 is greater than 24/18.
