Final answer:

The inequality to find the minimum number of weeks Susie needs to babysit to buy the snowboard is 98 + 72w <= 530. After simplifying, we get w <= 6, so option C) w <= 6 is the correct answer.

Explanation:

To find the minimum number of weeks, w, that Susie needs to babysit to purchase the snowboard, we can set up the following inequality:

98 + 72w \<= 530

This inequality represents the initial amount Susie has saved (
98 dollars) plus the amount she will save each week (72 dollars times the number of weeks, w) must be greater than or equal to the cost of the snowboard (
530 dollars).

Subtract 98 from both sides of the inequality:
72w \<= 432

Divide both sides by 72 to solve for w:
w \<= 6

The correct inequality is w \<= 6, meaning Susie needs to babysit for a maximum of 6 weeks to have enough money to buy the snowboard. Therefore, the correct answer is C) w \<= 6.

Answer:  He should put down $20450.

Step-by-step explanation:

Since we have given that

Amount he received on cost of goods sold = $19000

Amount he received on supplies = $1500

Amount he received on interest expense = $1250

Amount he paid as utilities expense = $1300

According to question, Edgar knows he needs to use an income summary account to use an income summary account to close out these temporary accounts,

So, Amount he should put down is given by

[tex]\$19000+\$1500+\$1250-\$1300\\\\=\$20450[/tex]

Hence, He should put down $20450.

Answer: There are 10 largest number of curtains she can make if she wants all the curtains to be exactly the same length.

There are 5 red fabrics and 11 gold fabrics that would be used for each curtain.

Step-by-step explanation:

Since we have given that

Number of yards of red fabric purchased by Jane = 50

Number of yards of gold fabric purchased by Jane = 110

We need to find the largest number of curtains she can make if she wants all the curtains to be exactly the same length.

For this we will find H.C.F. of 50 and 110.

Factors of 50 = 1, 2, 5, 10, 25, 50.

Factors of 110 = 1, 2, 5, 10, 11, 22, 55, 110.

So, Highest common factor of 50 and 110 is 10.

So, there are 10 largest number of curtains she can make if she wants all the curtains to be exactly the same length.

Number of yards of red fabric is given by

[tex]\frac{50}{10}=5[/tex]

Number of yards of gold fabric is given by

[tex]\frac{110}{10}=11[/tex]

Hence, there are 5 red fabrics and 11 gold fabrics that would be used for each curtain.

Answer:

The y intercept is -54/7

Step-by-step explanation:

We can find the slope

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

   = (-2--7)/(-8--1)

   = (-2+7)/(-8+1)

    =5/-7

  = -5/7

We can use the point slope form of the equation to find the equation of the line

y-y1 = m(x-x1)

y--7 = -5/7 (x--1)

y+7 = -5/7 (x+1)

Distribute the -5/7

y+7 = -5/7 x - 5/7

Subtract 7 from each side

y+7-7= -5/7 x -5/7 -7

y = -5/7x -5/7 -7

Get a common denominator of 7

y = -5/7x -5/7 -49/7

y = -5/7x -54/7

This is in the form

y= mx+b, where b is the y intercept

The y intercept is -54/7

Answer:

The unit costs are $0.77, $0.62 and $0.27 respectively.

Step-by-step explanation:

The unit price is simply the cost of the items divided by the amount of the items that are included. So, just take the cost and divide it.

$12.29/16 = $0.77 per unit

$19.98/32 = $0.62 per unit

$34.99/128 = $0.27 per unit

"The greatest number of flash cards that Juan can cut out of the piece of cardboard is 12.

To determine the greatest number of flash cards that Juan can cut out of the cardboard, we need to calculate the area of the cardboard and divide it by the area of one flash card.

 Let's denote the dimensions of the cardboard as [tex]\( L \) inches by \( W \)[/tex] inches, and the dimensions of each flash card as [tex]\( l \)[/tex]nches by [tex]\( w \)[/tex] inches. Given that the cardboard is[tex]\( L \times W \)[/tex]inches and each flash card is [tex]\( l \times w \)[/tex]inches, we can calculate the number of flash cards as follows:

 1. Calculate the area of the cardboard: [tex]\( \text{Area}_{\text{cardboard}} = L \times W \).[/tex]

2. Calculate the area of one flash card:[tex]\( \text{Area}_{\text{flash card}} = l \times w \).[/tex]

3. Divide the area of the cardboard by the area of one flash card to find the number of flash cards:[tex]\( \text{Number of flash cards} = \frac{\text{Area}_{\text{cardboard}}}{\text{Area}_{\text{flash card}}} \).[/tex]

 Given that[tex]\( L = 12 \), \( W = 12 \), \( l = 3 \), and \( w = 4 \)[/tex], we can substitute these values into our equations:

 1.[tex]\( \text{Area}_{\text{cardboard}} = 12 \times 12 = 144 \)[/tex]square inches.

2.[tex]\( \text{Area}_{\text{flash card}} = 3 \times 4 = 12 \)[/tex]square inches.

3. [tex]\( \text{Number of flash cards} = \frac{144}{12} = 12 \).[/tex]

 Therefore, Juan can cut out 12 flash cards from the piece of cardboard."

So we know that 2+2=4 and then we multiply that by 2 and then by X3, where we get 24X. Then we must subtract 16 from 1234322, which is 1234306. So we add 1234306 to 24X and get 24X+1234306 as our answer.

QUESTION 1a

We want to find the value of [tex]x[/tex] in the proportion,

[tex]6:9=x:72[/tex]

We rewrite the ratio on each side of the equation as fractions to obtain,

[tex]\frac{6}{9}=\frac{x}{72}[/tex]

We now multiply both sides of the equation by [tex]72[/tex] to get,

[tex]\frac{6}{9}\times 72=\frac{x}{72}\times 72[/tex]

This simplifies to  

[tex]\frac{6}{1}\times 8=\frac{x}{1}\times 1[/tex]

[tex]\therefore 48=x[/tex]

[tex]x=48[/tex]

QUESTION 1b

The given proportion is,

[tex]\frac{8}{3}=\frac{40}{x}[/tex]

We cross multiply to obtain,

[tex]8x=3\times 40[/tex]

We divide both sides by 8 to get,

[tex]x=\frac{3\times 40}{8}[/tex]

[tex]\Rightarrow x=\frac{3\times 40}{8}[/tex]

[tex]\Rightarrow x=\frac{3\times 5}{1}[/tex]

[tex]\therefore x=15[/tex]

QUESTION 1c

The given proportion is

[tex]\frac{x}{55}=\frac{3}{5}[/tex]

We multiply both sides by 55 to get,

[tex]\frac{x}{55}\times 55=\frac{3}{5}\times 55[/tex]

This simplifies to  

[tex]x=\frac{3}{1}\times 11[/tex]

[tex]\therefore x=33[/tex]

QUESTION 1d

The given proportion is,

[tex]\frac{33}{x}=\frac{11}{5}[/tex]

We cross multiply to get,

[tex]33\times 5=11x[/tex]

We now divide both sides by 11 to get,

[tex]\frac{33\times 5}{11}=x[/tex]

[tex]\Rightarrow x=15[/tex]

QUESTION 2

Since the recipe calls for 5 cups of flour for every 6 teaspoons of salt, we can write the ratio,

[tex]5:6[/tex]

Let a larger recipe of 15 cups of flour correspond to [tex]x[/tex] teaspoons of salt,

Then the proportion becomes,

[tex]5:6=15:x[/tex]

This implies that,

[tex]\frac{5}{6}=\frac{15}{x}[/tex].

We cross multiply to get,

[tex]5x=6\times 15[/tex]

We divide through by 5 to get,

[tex]x=\frac{6\times 15}{5}[/tex]

[tex]\therefore x=18[/tex]

Hence you will need 18 teaspoons of salt.

QUESTION 3

We were given that a 20-foot flagpole casts a 6-foot shadow.

We write this as a ratio to get,

[tex]20:6[/tex]

Let the nearby 30-foot building cast an x-foot shadow.

We can also write this as a ratio to get,

[tex]30:x[/tex]

The proportion now becomes,

[tex]20:6=30:x[/tex]

We cross multiply to get,

[tex]20x=6\times 30[/tex]  

This implies that

[tex]x=\frac{6\times 30}{20}[/tex]  

[tex]\Rightarrow x=9[/tex]  

QUESTION 4

If 15 corresponds to 4, we write the ratio,

[tex]15:4[/tex]

We want to find what number of ads corresponds to 300 columns. Let that number be x.

Then we have the ratio,

[tex]300:x[/tex]

The proportion is

[tex]15:4=300:x[/tex]

This implies that,

[tex]15x=300\times 4[/tex]

[tex]x=\frac{300\times 4}{15}[/tex]

[tex]x=80[/tex]

It must have 80 ads.

QUESTION 5

The given ratio is [tex]5:2[/tex],

Let the gallons of blue paint be [tex]x[/tex]

We can write the ratio [tex]x:8[/tex]

The required proportion is

[tex]5:2=x:8[/tex]

This implies that,

[tex]\frac{5}{2}=\frac{x}{8}[/tex]

We multiply both sides by 8

[tex]x=\frac{5}{2}\times 8[/tex]

[tex]x=20[/tex]

8 gallons of blue paint is needed

Answer:

p(x) = x³ - 7x² + 25x - 39

Step-by-step explanation:

complex roots occur as conjugate pairs, thus

2 + 3i is a root then 2 - 3i is also a root

given x = 3, x = 2 +3i, x = 2 - 3i are roots, then

(x - 3), (x - (2 + 3i))(x - (2 - 3i)) are the factors and

p(x) = a(x - 3)(x - 2 - 3i)(x - 2 + 3i) ← a is a multiplier

let a = 1

p(x) = (x - 3)((x - 2)² - 9i²)

       = (x - 3)(x² - 4x + 4 + 9) → [ i² = - 1 ]

       = (x - 3)(x² - 4x + 13)

       = x³ - 4x² + 13x - 3x² + 12x - 39

       = x³ - 7x² + 25x - 39

Eddie ordered 8 pizzas and gave each person 3/5 of a pizza. By dividing the total amount of pizza by the amount each person gets, we determine that there are roughly 13 people at the party.

To solve this problem, you have to divide the total amount of pizza by the amount each person gets. Eddie ordered 8 pizzas and he is giving each person 3/5 of a pizza. To find the number of people, you simply divide the total pizza by the pizza each person gets. The calculation would look like this: 8 divided by (3/5) is equal to 8 * (5/3), which is equal to 40/3, roughly 13.33.

Since we can't have a fraction of a person at the party, we would round this down to 13 people.

Answer: d. $7,463.77

Step-by-step explanation:

The formula to calculate the simple interest is given by :-

[tex]I=Prt[/tex], where P is the principal amount , r is the rate of interest ( in decimal) and t is time ( in years).                                                (1)

Given : Nate has an account that pays 2.76% simple interest per year and wants to accumulate $3,090 in interest from it over the next 15 years.

i.e. I= $3,090  ;  r= 2.76% =0.0276   and t= 15 years

Then, from (1), we have

Answer: In first question, Number of student's ticket(s) = 400

And number of adult's ticket(d) = 100

In second question, The goal of $3050 fell by $710

Step-by-step explanation:

1. Since, Here d represents the number of adult tickets and s represents the number of student tickets.

And, all 500 seats are filled for a​ performance.

Therefore, s + d = 500 ------(1)

Also, the price of one adult's  ticket = $8.50

The price of one student's ticket= $5.50

And, their is a revenue of $3050 by selling the tickets.

Thus, 8.50 d + 5.50 s = 3050 --------(2)

By solving the equation (1) and equation (2),

we get, s = 400, d=100

Thus, Number of student's ticket(s) = 400

And number of adult's ticket(d) = 100

2. According to the question,

s = 2 d  ----- (3)

s + d = 360 -----(4)

By solving equation (3) and (4),

We get, s = 240 and d = 120

thus, the total revenue after selling 360 tickets = 8.50 × 120 + 5.50 × 240 = $2340

But, the goal is $3050 ( according to the question)

Thus the total fall = 3050 - 2340 = $710

The city cultural center needs to sell 140 adult and 360 student tickets to meet their target revenue of $3050. If they sell 120 adult tickets and 240 student tickets (360 in total), they will fall $710 short of their goal.

In order to help the members of the city cultural center determine how to distribute tickets between adults and students to meet their target revenue, we have to solve a system of linear equations. The two equations we have for the system are 8.50d + 5.50s = 3050 (which represents the relationship between the price of adult and student tickets and the targeted total revenue), and d + s = 500 (which expects all 500 seats to be filled). Solving these equations, we find that d = 140 adult tickets and s = 360 student tickets need to be sold.

For the second part of the question, they sold 120 adult tickets and 240 student tickets, making a total of 360 tickets at one performance. The total revenue generated from these tickets is (120*8.50) + (240*5.50) = 1020 + 1320 = $2340. So, they fell $3050 - $2340  = $710 below the goal.

Statement of triangle proportionality:  

If a line parallel to one side of a triangle intersects the other two sides of the triangle, then that line divides these two sides proportionally.

From the statement: If [tex]FG || BC[/tex] then,

Show that: [tex]\frac{FB}{FA} = \frac{GC}{AG}[/tex]

Consider [tex]\triangle ABC[/tex] and [tex]\triangle GFA[/tex]

Reflexive property states that the value is equal to itself.

[tex]\angle BAC \cong \angle GAF[/tex] [Angle] {Reflexive property of equality}

Corresponding angles theorem states that if the two parallel lines are cut by a transversal, then the pairs of corresponding angles are congruent(i., e equal).

[tex]\angle ABC \cong \angle GFA[/tex] [Angle]

[tex]\angle ACB \cong \angle AGF[/tex] [Angle]

AA Similarity states that the two triangles have their corresponding angles equal if and only if their corresponding sides are proportional.

then, by AA similarity theorem:  

[tex]\triangle ABC \sim \triangle GFA[/tex]

By segment addition postulates:

AB = FA +FB and AC = AG + GC  

Corresponding sides in similar triangles are proportional  

[tex]\frac{AB}{FA} = \frac{AC}{AG}[/tex] .....[1]

Substitute AB = FA +FB and AC = AG + GC in [1]  

we have;

[tex]\frac{FA+FB}{FA} = \frac{AG+GC}{AG}[/tex]  

Separate the fraction:

[tex]\frac{FA}{FA} + \frac{FB}{FA} = \frac{AG}{AG} + \frac{GC}{AG}[/tex]

Simplify:

[tex]1 + \frac{FB}{FA} =1+ \frac{GC}{AG}[/tex]

Subtract 1 from both sides we get;

[tex]\frac{FB}{FA} =\frac{GC}{AG}[/tex] hence proved

6 tons 294 lb ÷ 3071 is approximately equal to 3.97138

To solve 6 tons 294 lb ÷ 3071, we need to first convert everything to the same unit.

Convert tons to pounds:

1 ton = 2000 pounds

6 tons = 6 * 2000 pounds = 12000 pounds

Combine the weight in pounds:

Total weight = 12000 pounds (6 tons) + 294 pounds

Total weight = 12294 pounds

Divide by 3071:

12294 pounds / 3071 = 3.97138

Therefore, 6 tons 294 lb ÷ 3071 is approximately equal to 3.97138
