Gianna wants to buy holiday presents for her family. At the holiday sale, every ornament is $3 and every stocking is $8. Although there will be 24 people at holiday dinner, she wants to buy more just in case someone brings a guest. She has allotted $200 for gifts. Write a system of linear inequalities to represent the situation

Answer:

graph a

Step-by-step explanation:

2*0 = 0

0+7 = 7

0<7; it is a solution

Given:

[tex]\overline{BD} \cong \overline{BE}[/tex]

DE bisects [tex]\overline{AB}[/tex].

DE bisects [tex]\overline{BC}[/tex].

To prove:

[tex]\overline{AB} \cong \overline{BC}[/tex]

Proof:

DE bisects [tex]\overline{AB}[/tex]

Then, [tex]AD=BD[/tex].         ...(i)

DE bisects [tex]\overline{BC}[/tex].

Then, [tex]BE=CE[/tex].           ...(ii)

We have,

[tex]\overline{BD} \cong \overline{BE}[/tex]        ...(iii)

Using (i), (ii) and (iii), we get

[tex]\overline{AD} \cong \overline{CE}[/tex]         ...(iv)

Adding (iii) and (iv), we get

[tex]\overline{BD}+\overline{AD} \cong \overline{BE}+\overline{CE}[/tex]

[tex]\overline{AB} \cong \overline{BC}[/tex]

Hence proved.

Answer:

Slope: 3/2

y intercept (0,-6)

Step-by-step explanation:

3x-2y=12

First, solve for y

2y=12-3x

divide each term by -2 and simplify

y=-6+[tex]\frac{3x}{2}[/tex] or y=[tex]\frac{3}{2}[/tex]x-6

Slope intercept form: y=mx+b

therefor m =[tex]\frac{3}{2}[/tex] and y (0,-6)

Answer:

The answer is "3 km ".

Step-by-step explanation:

Distance in (km): [tex]3 \to 1[/tex]

Elevation value in (m):  [tex]120 \to 40[/tex]

[tex]\to \frac{3}{1} = 3 \ km \\\\\to \frac{120}{40} =\frac{12}{4} = 3 \ km[/tex]

Answer:

The sum is $10

Step-by-step explanation:

Since Tony got $5 on Monday and $5 on Tuesday, we can add them together by doing 5+5. We can add 5 and 5 together to get a total of $10 that Tony has earned. This means that it isn't a sum of 0 but a sum of 10.

Answer:

We know

sin (A + B) = sin A cos B + cos A sin B

sin (A - B) = sin A cos B - cos A sin B

(A + B) + sin (A - B)

= sin A cos B + cos A sin B + sin A cos B - cos A sin B

= sin A cos B + sin A cos B

= 2 sin A cos B

Answer:

approximately $22438

Explanation:

If this is wrong which im pretty sure it isnt, im sorry :)

Answer: Annual Salary = $22,438

===================================================

Work Shown:

biweekly means every 2 weeks

There are roughly 52 weeks in a year, so there are 52/2 = 26 biweekly paychecks over the course of the full year.

So the annual salary is 26*863.00 = 22,438 dollars.

Answer:

They will spend less at the sunny side hotel

Step-by-step explanation:

The attachment completes the question.

From the question, we understand that there are 4 individuals involved.

And they will spend one night

First, we need to calculate the expenses in Traveler's hotel.

[tex]Rate = \$107.10[/tex] (for 3 people)

[tex]Additional\ Person = \$21.55[/tex] (for 1 person)

[tex]Breakfast = \$8.75 * 4[/tex] (for 4 people)

[tex]Tax = \$16.85[/tex]

Total Expenses

[tex]Total = \$107.10 + \$21.55 + \$8.75* 4 + \$16.85[/tex]

[tex]Total = \$107.10 + \$21.55 + \$35.00 + \$16.85[/tex]

[tex]Total = \$108.50[/tex]

For Sunny Side hotel:

[tex]Rate = \$152.95[/tex] (for 4 people)

[tex]Tax = \$21.34[/tex]

Total Expenses:

[tex]Total = \$152.95 + \$21.34[/tex]

[tex]Total = \$174.29[/tex]

By comparison, they will spend less at the sunny side hotel.

Answer:

Please find attached the bar model that shows the comparison between Abba's previous height to the height by which Abba grew over the past year

Step-by-step explanation:

A bar model, in mathematics, is defined as a graphic depiction of a given quantity represented by numbers presented in a rectangular box or bar form that is then applied in finding numerical relationship solutions

The height by which Abba grew over the past 1 year = 1 ft.

Abba's current height = 5 feet

Therefore, Abba's initial height = 5 feet - 1 foot = 4 feet

Please find attached the bar model that compares Abba's previous height to the height Abba grew over the past year created with Microsoft Visio

x° + 2y° = 180°   ⇒   2y° = 180° - x°

x° = 60°   {three sides of the same lengh, means three angles=60°}

2y° = 180° - 60°

2y° = 120°

y° = 60°

c. $400,000

Step-by-step explanation:

Let his total sales be $x.

Salary + commission =$45000

[tex] \therefore \: 25000 + 5 \% \: of \: x = 45000 \\ \\ \frac{5}{100} x = 45000 - 25000 \\ \\ \frac{1}{20}x = 20000 \\ \\ x = 20 \times 20000 \\ \\ x = \$\:400, 000[/tex]

Answer:

z = -44

Step-by-step explanation:

3/4 (x - 8) = 4

3(x - 8) = 16

3x - 24 = 16

3x = 40

x = 40/3

4 - 2x = -5x - z

4 = -3x - z

z = -3x - 4

z = -3(40/3) - 4

z = -40 - 4

z = -44

Answer:

Z=-44

Step-by-step explanation:

To figure out z. we have to figure out x first

So

3/4(x-8)=4

x-8=4÷3/4

x-8=4×4/3

x-8=16/3

3x-24=16

3x=16+24

3x=40

x=40/3

Now

4-2(40/3)=-5(40/3)-z

4-80/3=-200/3-z

z-68/3=-200/3

z=-200/3+68/3

z=-44

Answer:

essentially, in these problems, youre finding the square root of each number. the square root should be a decimal thats in between two other numbers, and those will be the integers that the value of the square root is between. unless the value is exactly a number and a half, it will be closer to one integer than the other. the work is below.

square root of:

59= 7.68

68= 8.246

78= 8.83

93= 9.64

104= 10.198

124= 11.14

33= 5.74

185= 13.6

215= 14.66

these are just the square roots. but, as you can see, each number is between two other whole numbers on a number line. So, just write down what those numbers are.

7.68 is between 7 and 8

8.246 is between 8 and 9

8.83 is between 8 and 9

9.64 is between 9 and 10

10.198 is between 10 and 11

11.14 is between 11 and 12

5.74 is between 5 and 6

13.6 is between 13 and 14

14.66 is between 14 and 15

so, we know thw numbers that each decimal is between, but we have to find which one each is cloest to. in order to do that, just know that if the decimal is more than .5 its closer to the larger number, and its its less than .5, its closer to thw smaller number.

7.68 is closer to 8

8.246 is closer to 8

8.83 is closer to 9

9.64 is closer to 10

10.198 is closer to 10

11.14 is closer to 11

5.74 is closer to 6

13.6 is closer to 14

14.66 is closer to 15

Step-by-step explanation:

Answer:

[tex]A_4[/tex]

Step-by-step explanation:

The cost of the e-readers and the subscription of their services are

[tex]A_1(t)=5t+350[/tex]

[tex]A_2(t)=10t+250[/tex]

[tex]A_3(t)=499[/tex]

[tex]A_4(t)=15t+179[/tex]

The functions are of the form

[tex]A(t)=mt+c[/tex]

Where [tex]m[/tex] is the monthly subscription cost and [tex]c[/tex] is the cost of the e-reader.

So, 15 dollars is the highest subscription cost which is of the 4th e-reader.

Hence [tex]A_4[/tex] has the highest subscription cost.

Answer:

The end behavior of a function f describes the behavior of the graph of the function at the "ends" of the x-axis. In other words, the end behavior of a function describes the trend of the graph if we look to the right end of the x-axis (as x approaches +∞ ) and to the left end of the x-axis (as x approaches −∞ ).
