Answer:

Ashley will have a total bill of $54.99

Step-by-step explanation:

1. Convert percentages into fractions or decimals

For fraction: divide 17 by 100 and remove the % sign.

[tex][17][/tex]%[tex]=\frac{17}{100}[/tex]

For decimal: move the decimal point 2 places to the left and remove the % sign.

[tex][17][/tex]%[tex]=0.17[/tex]

2. Multiply the decimal or fraction by the quantity that equals 100%

100%=47

[tex]17/100*47=0.17*47=7.99[/tex]

So hence, 17% is $7.99 of $47

3. Add the Tip with the Cost of the Meal (will give final answer)

to make things easier -

47+7=54

54+0.99=54.99

Answer:

see explanation

Step-by-step explanation:

To find the first 3 terms substitute n = 1, 2, 3 into the formula

(a)= 25 - (3 × 1) = 25 - 3 = 22 = 25 - (3 × 2) = 25 - 6 = 19= 25 - (3 × 3) = 25 - 9 = 16

The first three terms are 22, 19, 16

Note the difference between consecutive terms is - 3

19 - 22 = 16 - 19 = - 3

Continuing this pattern

(b)16 - 3 = 13 13 - 3 = 10 10 - 3 = 7  7 - 3 = 4  4 - 3 = 1  1 - 3 = - 2

The first negative term is - 2

Answer:

y = 4x + 8

Step-by-step explanation:

parallel mean the same slope so you can start with an equation of:

y = 4x + b

now we solve for b by inserting the coordinates and solving for b:

0 = 4 ( -2) + b

0 = -8 + b

8 = b

now put b into the equation:

y = 4x + 8

The amount Cheryl earned from the per time job is $82.

The three of them earned $550 from their part time jobs.

Li Ying earned $28.

Daniel earned 4 times as much as the total amount of Cheryl and Li Ying's earnings.

let

x = amount Cheryl earned

y =  amount Daniel earned

Therefore,

y = 4x + 112

y - 4x = 112

The three of them earned $550. Therefore,

x + y = 522

Let's combine the equation.

y - 4x = 112

x + y = 522

5x = 410

x = 410 / 5

x = 82

Therefore, Cheryl earned $82.

Answer:

[tex] 6x + 4 = 12x - 20 [/tex]

[tex] x = 4 [/tex]

Step-by-step explanation:

Let "x" be the number.

Product of 6 and x (6*x), increased by 4 = [tex] 6x + 4 [/tex]

Product of 12 and x, (12*x), decreased by 20 = [tex] 12x - 20 [/tex].

Set both expressions equal to each other and solve for x as shown below:

[tex] 6x + 4 = 12x - 20 [/tex] (equation)

Subtract 12 from both sides

[tex] 6x + 4 - 12x = 12x - 20 - 12x [/tex]

[tex] -6x + 4 = -20 [/tex]

Subtract 4 from both sides

[tex] -6x + 4 - 4 = -20 - 4 [/tex]

[tex] -6x = -24 [/tex]

Divide both sides by -6

[tex] \frac{-6x}{-6} = \frac{-24}{-6} [/tex]

[tex] x = 4 [/tex]

The answer to this question is: 7

The change in temperature from the morning to the afternoon is 7°F.

Given that, Alvin woke up in the morning, it was –9°F. By the afternoon, the temperature had risen to –2°F.

We need to find what was the change in temperature from the morning to the afternoon.

Temperature change is a process whereby the degree of hotness of a body (or medium) changes.

You subtract the final temperature from the starting temperature to find the difference.

Now, change in teperature=-2-(-9)

=-2+9=7

Therefore, the change in temperature from the morning to the afternoon is 7°F.

Answer:

To find c you know that angles on a straight line equal 180° (supplementary angles). So 70+30+∠C=180.

Now we can solve this.

100+c=180.

Move the 100 over to the other side.

100-100+c=180-100

Simplify.

∠C=80°

Because we know that the two lines with double arrows are parallel, we can use the rule that alternate interior angles are congruent. This means that ∠E=70.

∠E=70°

Since the total sum of the angles in a triangle are equal to 180°, we know that ∠D+∠C+∠E=180. Because we already know ∠C and ∠E we can put those numbers in for them. 80°+70°+∠D=180°. Now we can solve this.

80+70+D=180

Simplify this.

150+D=180

Now we move the 150 over to the other side to get D by itself.

150-150+D=180-150

Simplify.

D=30

∠D=30°

Now we can find the vertical angle opposite ∠A by using the alternate interior angles rule again this time using the parallel lines with only one arrow on them. The vertical angle opposite ∠A=30°. Since vertical angles are congruent ∠A=30°.

∠A=30°

We are going to use the alternate angles rule one more time to solve for ∠B (this rule is very important when dealing with parallel lines), we could also use the corresponding angles rule but for simplicity we will just stick with the alternate angles rule. Because the vertical angle opposite ∠A is equal to 30°, we can see that the supplementary angle opposite ∠B=30°. Because this angle is supplementary with B we know that 30+B=180.Now we can solve this.

30+B=180

Now we move the 30 over to the other side.

30-30+B=180-30

Simplify.

B=150

∠B=150°

Step-by-step explanation:

The election poll indicates a close race between Candidate Smith and Candidate Jones, with a margin of error of 3 percent.

Given that,

Election poll of 1,000 people conducted

48 percent of voters favor Candidate Smith

50 percent of voters favor Candidate Jones

Margin of error is 3 percent

Based on the election poll,

We can conclude that there is a close race between Candidate Smith and Candidate Jones.

With Candidate Smith at 48 percent and Candidate Jones at 50 percent, it suggests a tight competition.

However, it's important to consider the margin of error of 3 percent.

This means that the actual support for each candidate could vary within this range.

Therefore, while this poll provides valuable insights, it is not definitive and other factors should also be considered.
