Answer:

$0.50

Step-by-step explanation:

Suppose that a person  bought  six T-bone steaks that cost $15.99 per pound

The weight that is listed on the package is 5.77 pounds.

The scale that weighed the package is accurate to within 1/32 pound

Let assume x is the range of the  weight listed on the package,

Then:

[tex]|x-5.77| \leq \dfrac{1}{32} \ --- \ (1)[/tex]

Using the method of absolute value inequality;

[tex]- \dfrac{1}{32} \leq x -5.77 \leq \dfrac{1}{32}[/tex]

[tex]5.77- \dfrac{1}{32} \leq x \leq \dfrac{1}{32}+ 5.77[/tex]

[tex]5.77- 0.03125\leq x \leq 0.03125+ 5.77[/tex]

[tex]5.73875 \leq x \leq 5.80125[/tex]

The amount per kilogram undercharged or overcharged is :

[tex]=\dfrac{1}{32} \times 15.99[/tex]

= $0.50

Answer:

U'(-3, 1), M'(-1, 4), L'(-2, 0)

Step-by-step explanation:

To do a translation of 5 units up, add 5 to the y-coordinate of each point.

U(-3, -4) ----> U'(-3, -4 + 5) = U'(-3, 1)

M(-1, -1) ----> M'(-1, -1 + 5) = M'(-1, 4)

L(-2, -5) ----> L'(-2, -5 + 5) = L'(-2, 0)

Answer: The translated points are U'(-3, 1), M'(-1, 4), L'(-2, 0)

Answer:   -21x + 5y = 9

Step-by-step explanation:

The standard form says that  Ax + By=C  

So to covert y = 4.2x + 1.8 into  subtract 4.2 from both sides.

    y = 4.2x + 1.8

-4.2x   -4.2x

-4.2x + 1y = 1.8       Now it is written in standard form and to make the decimals integers we will multiply both sides by 10.

-4.2x(10) + 1y(10) = 1.8(10)

-42x + 10y = 18  which reduces to -21x + 5y = 9

Answer: 48.75

Step-by-step explanation:

Answer:

41

Step-by-step explanation:

BDA = DBC+CBA

84=5x+3 + 6x-7

Combine like terms

84 = 11x-4

Add 4 to each side

84+4= 11x -4+4

88 =11x

Divide each side by 11

88/11 = 11x/11

8 = x

We want angle  ABC

ABC = 6x-7

       =6*8 -7

      =48-7

     =41

Answer:

∠ABC   = 41°

∠ DBC  = 43°

Step-by-step explanation:

6x-7 + 5x+3 = 84

6x + 5x = 84 - 3 + 7

11x = 88

x = 8

∠ABC   = 6x-7

           = 6*8 - 7

           = 48 - 7

           = 41°

∠ DBC = 5x + 3

           = 5*8 + 3

           = 40 + 3

            = 43°

Answer:

Solution : (36, 42)

Step-by-step explanation:

It mention that the image is dilated by a scale factor of 6, and hence we will have to multiply each coordinate by 6 to receive the dilated point. Here we only want the dilation of point B,

B' = (6 [tex]*[/tex] 6, 7 [tex]*[/tex] 6) = (36, 42)

If quadrilateral ABCD is dilated by a scale factor of 6, then the coordinates of point B' are (36, 42).

The total length of the road is 3,140 kilometers.

Answer:

1st or each day=314km

Let x in km be the total km for 10 days

10=x

Answer:

x = 15 and y = 30

Step-by-step explanation:

We see that 4x + 15 + 5x + 30 = 180.

We can solve for x:

9x + 45 = 180

9x = 135

x = 15.

We also see that 5x + 30 is equal to 3y + 15, so we can solve for y:

5x + 30 = 3y + 15

5 (15) + 30 = 3y + 15

3y = 75 + 30 - 15

3y = 90

y = 30.

Answer:

Lines p and t are parallel, so the alternate exterior are congruent; x = 130

Step-by-step explanation:

hope you like it it :) god bless you all

we love cheating in iready :3

The correct answer is 2. Lines q and r are parallel, so the interior angles are supplementary; x = 130

The types of transversal angles are as follows

Option 1. is incorrect because Lines p and t are not parallel

Option 3 is incorrect because alternate exterior angles is x= 130°

Option 4 is incorrect  because x is not corresponding angle to 50°

Hence , Option 2 is correct and rest options are incorrect.

Since b and h are the same here, we have b^2= 2y, [tex]b=\sqrt{2y}[/tex].

And we have FC=[tex]\frac{\sqrt{2y} }{2}[/tex].

Area of shaded triangle: [tex]\frac{1}{2} (\frac{\sqrt{2y} }{2})(\frac{\sqrt{2y} }{2})[/tex].

Answer:

Ali's heart rate is 135 times per minute.

Step-by-step explanation:

Let Ali's heart rate be denoted by x times per minute.

It is provided that Ben's heart beats 18 times per minute more than Ali.

The ratio of their heart rates was 15:17.

That is:

[tex]\frac{15}{17}=\frac{x}{x+18}[/tex]

Solve for x as follows:

[tex]\frac{15}{17}=\frac{x}{x+18}[/tex]

[tex]15(x+18)=17x\\15x+270=17x\\2x=270\\x=135[/tex]

Thus, Ali's heart rate is 135 times per minute.

Step-by-step explanation:

The question lacks Allen's workings. Find it below.

Step Work Reasoning

−8.3 + 9.2 − 4.4 + 3.7 Original problem

1 −8.3 + 9.2 + 4.4 + 3.7 Additive inverse

2 −8.3 + 4.4 + 9.2 + 3.7 Commutative property

3 −8.3 + (4.4 + 9.2 + 3.7) Associative property

4 −8.3 + 17.3 Simplify

5 9 Simplify

Given the equation −8.3 + 9.2 − 4.4 + 3.7, to solve this we are going to be using different properties.

Given three values A, B and C, the following are true:

A-B = A+(-B) Additive inverse

(A+B)+C = A+(B+C) Commutative property

Applying this laws to correct Allen's calculation

Original problem

−8.3 + 9.2 − 4.4 + 3.7

Applying the additive inverse property

−8.3 + 9.2 +(− 4.4) + 3.7 {since product of plus and minus sign still gives a minus sign)

Rearranging the equation based on signs according to the associative property we will have:

−8.3 +(-4.4) + 9.2 + 3.7

Using the commutative property to separate the positive variables from negative variables will give:

{−8.3 +(-4.4)} + {9.2 + 3.7}

Since {−8.3 +(-4.4)} + {9.2 + 3.7} = {9.2 + 3.7} + {−8.3 +(-4.4)}

Simplify the expressions in parenthesis:

= {−8.3 +(-4.4)} + {9.2 + 3.7}

= (-8.3-4.4)+(9.2+3.7)

= (-12.7)+(12.9)

= 0.2

From the above calculation, it can be seen that Allen made an error while using the additive inverse property in his first step. He should not have removed the minus sign. The negative sign was removed from step 1 which makes the remaining steps of his calculation to be wrong. Instead of replacing -4.4 directly with +4.4 he should have used the additive inverse property by replacing -4.4 with +(-4.4).

Apply imaginary number rule : i² = -1

x = year

y = amount of hydrocarbon emissions in grams, per mile driven

m = rate of change = slope

m = (y2 - y1)/(x2 - x1)

m = (0.8 - 3.4)/(2007 - 1972)

m = -2.6/35

m = -0.0742857 approximately

The approximate rate of change is about -0.0742857 grams per year. The negative rate of change indicates the per mile hydrocarbon amount has gone down by about 0.0742857 grams each year.

Answer:

$11.57

Step-by-step explanation:

First, find the total amount they need to pay.

Add the bill for lunch and the tip amount.

bill + tip

The bill was $29.46 and the tip was $5.25

$29.46 + $5.25

$34.71

The total amount with tip is $34.71

Next, find the amount each person should pay.

They want to divide the amount equally. There are 3 total people ( Jack + 2 friends = 3 people). Divide the total ($34.71) by 3.

$34.71 /3

$11.57

Each person should pay $11.57
