Rachel can buy licorice sticks for $0.75 and cherry candies for $0.50 and has a budget of $25 if her expenses are represented by the equation 0.75x+0.05y=25 where x is the number of licorice sticks and y is the number of cherry candies, how many cherry candies can she But if she wishes to spend the entire $25 on cherry candies

You can buy 50 of the cherry candies with all of the 25$ because you do 25 divided by 0.50 and get 50 and then if you would like to check that do 50 x 0.50 and you will still get 25$

Ava graphs the function h(x) = x2 + 4. Victor graphs the function g(x) = (x + 4)2. Which statements are true regarding the two graphs? Check all that apply. Ava’s graph is a vertical translation of f(x) = x2. Victor’s graph is a vertical translation of f(x) = x2. Ava’s graph moved 4 units from f(x) = x2 in a positive direction. Victor’s graph moved 4 units from f(x) = x2 in a positive direction. Ava’s graph has a y-intercept of 4. Victor’s graph has a y-intercept of 4.

Answers:

Ava’s graph is a vertical translation of f(x) = x^2.

Ava’s graph moved 4 units from f(x) = x^2 in a positive direction.

Ava’s graph has a y-intercept of 4.

Given:

Ava graphs the function  h(x) = x^2 + 4.

Victor graphs the function  g(x) = (x + 4)^2

To find y intercept we plug in 0 for x

 h(x) = x^2 + 4

 h(x) = 0 + 4= 4

So ,Ava’s graph has a y-intercept of 4.

Ava graphs the function  h(x) = x^2 + 4

If any number is added at the end then the graph will be shifted up. 4 is added at the end so there will be vertical translation.

Hence , Ava’s graph is a vertical translation of f(x) = x^2. Also Ava moved 4 units up from f(x) = x^2 in a positive y- direction.

Victor graphs the function  g(x) = (x + 4)^2

If any number added with x then the graph will be shifted left. the graph will be shifted in negative x direction.

QUESTION POSTED AT 22/01/2020 - 02:18 AM

What number should be added to both sides of the equation to complete the square? x2 – 10x = 7

we have

x^{2} -10x=7

Complete the square. Remember to balance the equation by adding the same constants to each side

to complete the square adds (10/2)^{2}=25 both sides

so

x^{2} -10x+25=7+25

x^{2} -10x+25=32

Rewrite as perfect squares

(x-5)^{2}=32

Square root both sides

x-5=(+/-)\sqrt{32}

x=5(+/-)\sqrt{32}

x1=5+\sqrt{32}

x2=5-\sqrt{32}

therefore

the answer is

The number is 25

QUESTION POSTED AT 22/01/2020 - 02:18 AM

A sequence is defined recursively using the formula f(n + 1) = f(n) – 5 . Which sequence could be generated using this formula? *1, –5, 25, –125, ... *2, 10, 50, 250, ... *3, –2, –7, –12, ... *4, 9, 14, 19, ...

Answer:

Option C. 3, -2, -7, -12....

Step-by-step explanation:

The sequence is defined recursively using the formula f(n+1) = f(n) - 5

We have to identify the sequence generated by this formula.

B). 1, -5, 25, -125.....

f(n+1) = -5 and f(n) = 1

Therefore - 5 = 1 - 5

⇒ -5 ≠ -4

This sequence is not following the formula.

B). 2, 10, 50, 250.........

f(n+1) = 10 and f(n) = 2

Now we use the formula

10 = 2 - 5

10 ≠ -3

This sequence is not following the formula.

C). 3, -2, -7, -12

f(n+1) = -2 and f(n) = 3

We put this value in the formula

-2 = 3 - 5

-2 = -2

Therefore , the sequence is following the formula.

D). 4, 9, 14, 19........

f(n+1) = 9 and f(n) = 4

9 = 4 - 5

9 ≠ -1

Therefore the formula is not applicable to form this sequence.

Option C. is the answer.

QUESTION POSTED AT 22/01/2020 - 02:16 AM

Jillian’s school is selling tickets for a play. The tickets cost $10.50 for adults and $3.75 for students. The ticket sales for opening night totaled $2071.50. The equation 10.50a + 3.75b = 2071.50, where a is the number of adult tickets sold and b is the number of student tickets sold, can be used to find the number of adult and student tickets. If 82 students attended, how may adult tickets were sold?

Okay, so this is a multi-step problem. If there are 82 students, and the cost was $3.75 PER student, we would multiply 3.75 times 82 to get 307.50, and now we would subtract the total amount of sales, ($2,071.50), MINUS the ticket sales made by students, ($307.50). So 2,071.50 - 307.50 = 1,764.
So this means that they made $1,764 in ticket sales from ADULTS. Now to find out how many adults were THERE, (or the amount of adult tickets that were sold), we will divide 1,764 divided by the price of each adult ticket, ($10.50), which will be 1,764 divided by 10.50 = 168.
168 adult tickets were sold.
I hope I helped! =D

Since the area of the triangle is equal to bh/2, we can express the area in terms of x as x(6x + 1)/2 and equate in to 13. Thus x(6x + 1)/2 = 13 x(6x + 1) = 26 6x² + x = 26 6x² + x - 26 = 0 Thus, the answer is 6x² + x - 26 = 0.

Triangle HIJ has coordinates H(–1, 1), I(1, 4), and J(1, 3). Graph the triangle and its translation 3 units to the right and 2 units down. What are the coordinates of I.

Answer:

(4,2)

Step-by-step explanation:

We have been given that triangle HIJ has coordinates H(-1,1), I(1,4) and J(1,3). We are asked to find the coordinate of point I after a translation of 3 units to the right and 2 units down.

The translation of 3 units to right means that we need to add 3 to x-coordinates.

The translation of 2 units down means that we need to subtract 2 from y-coordinates.

H(-1,1)\rightarrow H'(-1+3,1-2)=H'(2,-1)

I(1,4)\rightarrow I'(1+3,4-2)=I'(4,2)

J(1,3)\rightarrow J'(1+3,3-2)=I'(4,1)

Therefore, the coordinates of point I' after translation would be (4,2).

The first incorrect step would be step number three since when solving Absolute-Value Equations, when you isolate the Absolute-Value bars and the terms inside of it, the next step should be to make two equations: one that equals the original number given on the right side of the equal sign and one that is the opposite of the number on the equal sign.

Paul is going to have the exterior of his home painted. Painting USA charges $75.00 to come out and evaluate the house plus $25.00 per hour of labor. Upscale Home Painting does not charge to evaluate the house. However, they charge $40.00 per hour. If it takes 25 hours to paint Paul’s house, the most cost effective company will be? The cost of painting the house will be the same for both companies if the number of hours required to paint Paul’s house is?

The most cost effective company will be:

$75.00
25 hours

Painting USA: Fixed Cost: $75; Variable Cost: $25x
Total Cost = 75 + 25(25) = 75 + 625 = 700

Upscale Home Painting: Fixed Cost: $0; Variable Cost: $40x
Total Cost = 40(25) = 1,000

The most cost effective company will be Painting USA whose charges will amount to $700


The cost of painting the house will be the same for both companies if the number of hours required to paint Paul's house is:

Painting USA:
Total Cost: 75 + 25(25) = 75 + 625 = 700

Upscale Home Painting
Total Cost: 40(16.5) = 40 + 660 = 700

The cost of painting the house will be the same for both companies if the number of hours required to paint Paul's house is approximately between 16.5 and 25 hours.

Multiplying a trinomial by a trinomial follows the same steps as multiplying a binomial by a trinomial. Determine the degree and maximum possible number of terms for the product of these trinomials: (x2 + x + 2)(x2 – 2x + 3). Explain how you arrived at your answer.

To determine the degree of the product of the given trinomials, you would multiply the term with the highest degree of each trinomial together. Both trinomials are degree 2, and when you multiply x2 by x2, you add the exponents to get x4. Thus, the degree of the product is 4. If the product is degree 4, and there is only one variable, the maximum number of terms is 5. There can be an x4 term, an x3 term, an  x2 term, an x term, and a constant term.

The maximum rate at which a bus can accelerate or decelerate is 2m/s^2 it has a maximum speed of 60km/h. Find the shortest time the bus can take to travel between two bus stops 1 km apart on a straight stretch of road.

Question did not specify that bus was stationary at any point.

60 km/h = 60000/3600  m/s = 16.67 m/s
Shortest time to travel = distance / speed = 1000/(50/3)=60 sec. = 1 min. 

If we assume bus was stationary at each stop (if passengers have to get on/off), then acceleration is involved.

Note: at 2 m/s, the bus accelerates from stationary to 60 km/h in 8 seconds!  

Using kinematics equation
2aS=v^2-u^2
we have
a=acceleration = 2m/s
S=distance
u=0 initial speed
v=final speed=50/3 m/s=60 km/h
Distance travelled = (v^2-u^2)/(2a)=(50/3)^2/(2*2)=625/9 m=69.33 m.
Remaining distance at 60 km/h
=1000-69.44-69.44=861.11 m
time to travel = 861.11/(50/3)=51.67 s.
Time to accelerate/decelerate= (50/ 3)/2 m/s /  m/s^2 = 8.333 s.
Total time = 51.67+2*8.33=68.33 s.

In which number is the value of 5 ten times the value of 5 in 10.059

Answer:

12.57

Step-by-step explanation:

The 5 in the number 10.059 is placed at the hundredth place.

i.e. the value of 5 in 10.059 is 0.05.

Now, ten times the value of 5 = 10 × 0.05 = 0.5

So, we need to find a number in which the 5 has value 0.5 and is placed at the tenths position.

Let us take 12.57.

We see that 5 is placed at the tenths place and has value 10 times the value of 5 in 10.059.

Hence, the number comes out to be 12.57.
