Answers

Answer 1

The correct answer would be C. The percent increase is approximately 21%

Answer 2

Answer:

the third answer, 21%

Step-by-step explanation:

the change was 15% and the original was 70 so,

15/70

=.21

Let’s make a number line

0. 1/5. 2/5. 3/5. 4/5. 1
——————————————

4/5 is closer to 1 so we can round it to 1.

1 8/9 can be separated into 1 + 8/9

Here is another number line

0. 1/9. 2/9. 3/9. 4/9. 5/9. 6/9. 7/9. 8/9 1
—————————————————————

8/9 is closer to 1, so we can round it to 1.

Now we have 1+1 = 2

The question asks us to multiply both fraction using the estimations.

So instead of,
4/5 x 1 8/9.

We use
1 x 2,
Which is =2

(So the answer is 2 or b)

According to the synthetic division below, which of the following statements
are true?
Check all that apply.

Answers

The question is not complete, so i have attached it.

Answer:

Options A, B & E are correct

Step-by-step explanation:

In the synthetic division attached, we see that:

: 2 , -2 & -12 are the coefficient of the dividend of the function 2x² - 2x - 12

: The divisor is 3

Thus;

x = 3 is a root of f(x) = 2x² - 2x - 12

Thus, (x - 3) is a factor of the dividend which is the function f(x) = 2x² - 2x - 12

- Now, from the attached image, the coefficients of the quotient are 2 , 4

- The quotient will be 1 degree less than the dividend since it was divided by the factor (x - 3)

The degree of the dividend will be 2 since it contains x²

Thus, the degree of the quotient will be 1

Therefore, the quotient in factor form is (2x + 4)

Looking at the given statements in the options;

- Option A is true, because we have established earlier that 3 is a root of f(x) = 2x² - 2x - 12

- Option B is true because we have established that (x - 3) is a factor of 2x² - 2x - 12

- Option C is not true because the factor is (x + 3) and not (x - 3)

-Option D is not true because the root is 3 and not -3

- Option E is true because we have established that quotient as a factor is: (2x + 4)

Thus, the correct options are A , B , E

You are riding a train. Your carry-on bag can weigh no more than 50 pounds. Your bag weighs 38 pounds.
Which inequalities represent how much weight you can add to your bag?
W > 50 - 38
50 > W - 38
38 + w < 50
W < 50 - 38
Can you add both a 9-pound laptop and a 5-pound pair of boots to your bag without going over the weight limit?
Yes, the total being added is 4 pounds, which is a solution of the inequality
No, the total being added is 14 pounds, which is not a solution to the inequality
Yes, the added weight needs to be less than 38 pounds, and 9 plus 5 is less than 38.
No, the added weight needs to be at least 38 pounds, and 9 plus 5 is less than 38.

Answers

Answer:

Let the additional weight that can be added be = x

Current weight of the bag = 38 pounds

Total weight can be = 50 pounds

The equation becomes:

38+x < or equal 50

x < or equal 50-38=12

Hence, a weight of 12 pounds cab be added to the current wight.

5, 18, 6, 18, 13 find the interquartile range (SHOW WORK)

Answers

Answer:

12

Step-by-step explanation:

The interquartile range is the difference between the upper quartile and the lower quartile.

Firstly find the median of the data.

The median is the middle value of the data arranged in ascending order. If there is no exact middle value then it is the average of the values either side of the middle.

5,  6,  13,  18,  18 ← data in ascending order

           ↑ middle value

median = 13

The upper quartile Q₃ is the middle of the data to the right of the median

13,  18,  18

       ↑ middle value

Q₃ = 18

The lower quartile Q₁ is the middle value of the data to the left of the median

5,  6,  13

    ↑ middle value

Q₁ = 6

Interquartile range = Q₃ = Q₁ = 18 - 6 = 12

           

Consider the line y = 3x - 1.
Find the equation of the line that is perpendicular to this line and passes through the point (-8, 3)
Find the equation of the line that is parallel to this line and passes through the point (-8, 3).

Answers

Answer:

y = -1/3x + 1/3

Step-by-step explanation:

The slopes of perpendicular lines are negative reciprocals.

The given line is

y = 3x - 1

This equation is written in the slope-intercept form, y = mx + b, where m is the slope.

slope of given line = m = 3

slope of perpendicular line = -1/3

Now we need the equation of the line with slope -1/3 that passes through the point (-8, 3)

y = mx + b

y = -1/3x + b

3 = (-1/3)(-8) + b

3 = 8/3 + b

9/3 = 8/3 + b

b = 1/3

y = -1/3x + b

y = -1/3x + 1/3

3x-5x=10-6=

-2x=4

x=-2

Answer:

x = -2

Step-by-step explanation:

3(x - 6) + 8 = 5x - 6

Distribute;

3x - 18 + 8 = 5x - 6

Collect like terms;

3x - 10 = 5x - 6

Subtract 5x from both sides;

-2x - 10 = -6

Add 10 to both sides;

-2x = 4

Divide both sides by -2

x = -2

Raven needs new winter boots. Both ShoeTown and LaceUp shoe stores carry the boots she wants to buy. The boots are regularly priced $85.95, but both stores are running sales. ShoeTown has the boots marked down 15%. LaceUp has the boots marked down 10%, plus Raven has a $5 coupon she can use on the boots after the mark down is applied.Raven’s friend, Becca, tells Raven there is an online shoe store called Run, Don’t Walk that has the boots she wants for only $71.99. If Raven buys the boots in a local store, she will have to pay 7.16% sales tax on her purchase. If Raven buys the boots online, she won’t have to pay sales tax, but she will have to pay $6.50 for shipping.

Answers

Raven should buy the boots at Shoe Town because this offers the best final price.

To determine which one is the best store for Raven let's calculate the price in each case.

Shoe Town

Total price:

Initial price - Mark down  + Sales tax

85.95 - 15% + 7.16 %85.95 - 12.89 + 7.16 %73.06 + 7. 16%73.06 + 5.23 = 78.29

Lace Up

Total price:

Initial price - Mark down - Coupon + Sales tax

85.95 - 10% - 5 + 7.15%89.95 - 8.99 - 5 + 7.15%80.96 - 5 + 7.15%75.96 + 7.15%75.96 + 5.43 = 81.39

Write, in slope intercept form, the equation of the line that passes through (8, -9) and has a slope of -5/4.

Answers

Answer:

The equation in the slope-intercept form will be:

[tex]y=-\frac{5}{4}x+1[/tex]

Step-by-step explanation:

Given

slope = m = -5/4point = (8, -9)

As we know that the equation of a line in point-slope form is

[tex]y-y_1=m\left(x-x_1\right)[/tex]

substituting the values m = -5/4 and point = (8, -9)

[tex]y-\left(-9\right)=\frac{-5}{4}\left(x-8\right)[/tex]

[tex]y+9=\frac{-5}{4}\left(x-8\right)[/tex]

Writing the equation in slope-intercept form

[tex]y=mx+b[/tex]

where m is the slope, and b is the y-intercept

so the equation of the line in slope-intercept form becomes

[tex]y+9=\frac{-5}{4}\left(x-8\right)[/tex]

subtract 9 from both sides

[tex]y+9-9=\frac{-5}{4}\left(x-8\right)-9[/tex]

[tex]y=-\frac{5}{4}x+1[/tex]

Therefore, the equation in the slope-intercept form will be:

[tex]y=-\frac{5}{4}x+1[/tex]

2. None of them will taste different as the ratios are same.

Step-by-step explanation:

First of all we have to write the three ratios as fractions to see if the ratios are equivalent ratios or not.

We will see the water to cups ratio

The ratios in fractional form are:

[tex]=\frac{1}{3}\\=\frac{4}{12}\\=\frac{6}{18}[/tex]

Putting all the ratios together

[tex]\frac{1}{3} = \frac{4}{12} = \frac{6}{18}\\\frac{1}{3} = \frac{1}{3} = \frac{1}{3}[/tex]

1. It can clearly observed that all the ratios that are written in fractional form simplify to same fraction which means that all the ratios are equivalent. All the recipes will taste same.

2. None of them will taste different as the ratios are same.
