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$

Well, to find a circles circumference, C=D* pi. if d =10, 10 * pi (or 3.14 for now), C= 31.4. so the answer is false. It is measuring distance as a radius instead of diameter.

QUESTION POSTED AT 22/01/2020 - 02:19 AM

A fountain on a lake sprays water in a parabolic arch modeled by the equation y = −0.4x2 + 3x, where y is the height in feet and x is the horizontal distance. A beam of light is passed through the fountain to create a rainbow effect. If the beam is directed at an angle modeled by the equation -2.2x + 4.9y = 8.18, at what distance from the ground will the beam first touch the water spray?

To answer this question, we are given with two equations y = −0.4x^2 + 3x which decribes the parabolic arched water of the lake and -2.2x + 4.9y = 8.18 which models the direction of the beam. To find the distance from the ground, y  which the beam first touch that water spray, we get the expression of the first equation in terms of y and substitute to the second equation. x is equal to 0.743 meters y is equal to 2.0 meters. Answer is 2 meters.

QUESTION POSTED AT 22/01/2020 - 02:17 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.

m= \frac{10-2}{-6-12}
m= -\frac{4}{9}

Then numbers 11-100 have an order of magnitude 2.
Then numbers 111-1000 have an order of magnitude 3.
Then numbers 1111-10000 have an order of magnitude 4.
Then numbers 11111-100000 have an order of magnitude 5.

The area of a triangle whose height is 1 more than 6 times its base is 13 square feet. if the base of a triangle is x feet which equation models

Since the choices were not given, the ones below were retrieved from another source: A) 6x^2+x-12=0 B) 6x^2+x-13=0 C) 6x^2+x-26=0 D) 36x^2+6x-26=0 If we let x represent the dimension of the base, then we can represent height as (6x +1). 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.

A). area of a rectangle equal length time width 

in this case 

38,25 = 9*h

h = 38,25/9 = 4,24 

B). area of a parallelogram equal 44,4 square feet and its height is 7,4 feet

Area = length of base time height 

44,4 = l * 7,4

l = 44,4 / 7,4 = 6 ft

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.

The volume of a pyramid that fits exactly inside a cube is 49 cubic feet. What is the volume of the cube? 7 cubic feet 147 cubic feet 241 cubic feet 2401 cubic feet

If the pyramid fits perfectly in a cube, this means that its base is a square and its height has the same value as the side of the square. Let x be the measure of the sides of the cube. The volume of the cube (Vc),
                                    Vc = x³   ; 49 ft³ = x³    ; x = 49^(1/3)

The volume of the pyramid is,
                                Vp = (1/3)(x²)(x) = (1/3)(x³)
Substituting the known values,
                                 Vp = (1/3)((49^(1/3))³ = 16 1/3 ft³

Thus, the volume of the pyramid is approximately 16.33 ft³.
