Answers

Very interesting and inspiring problem. Wish there are more of these.

First, we know that a possible equation of L2 is y=1, then c=-1 => -y=-1 or y=1.
Of course, c could be just any negative number so that L2 lies above the x-axis.
=> c<0 ..........................................(III) is true

Next, we note that L1 has a negative intercept, that meant that when x=0, y<0. Go back to the original equation
ax+by=-1 => when x=0, by=-1, so b>0 in order for y to be negative. So
b>0.
We already know that c<0, so
b>c .....................................................................(II) is true

Further, we note that L2 has a negative slope. From the definition of slope, m, where m=-a/b
=>
m=-a/b<0 => a/b>0.
We already know that b>0, so for a/b>0, a>0. Therefore
a>0 ...................................................................(I) is true

So we have established the truth values of (I), (II) and (III).
It will be up to you to select the answer choices.

Write the following statement as an equation and solve. Jake Drewrey, owner of Jake's Landscape Service, knows that one of his fertilizer tanks holds four times as many gallons of liquid fertilizer as a second tank. The two tanks together hold 286 gal. If both tanks are filled to capacity, how many gallons of fertilizer does each tank hold?

Answers

Final answer:

The equation is : x + 4x = 286, where x represents the smaller tank's capacity.

Explanation:

To write the statement as an equation and solve it, let's denote the smaller tank's capacity as x gallons. Therefore, the larger tank would be 4x gallons because it holds four times as much. The problem states that together they hold 286 gallons, which gives us the equation:

x + 4x = 286

Combining like terms, we get 5x = 286. Dividing both sides of the equation by 5 to solve for x, we find:

x = 286 / 5

x = 57.2

Therefore, the smaller tank holds 57.2 gallons, and the larger tank holds 4 times that amount, which is 57.2 * 4 = 228.8 gallons.

Answers

Answer:

Step-by-step explanation:

Apex just did the quiz:))

Option A is correct, No, partly because they will be able to claim a dependent.

What is Income tax?

An income tax is a tax imposed on individuals or entities in respect of the income or profits earned by them. Income tax generally is computed as the product of a tax rate times the taxable income.

Having a dependent usually makes the 1040EZ form insufficient for most taxpayers, as the 1040EZ form is only recommended for those with simple tax situations.

In this case, the couple can claim their dependent as a tax credit, which is not possible on the 1040EZ form.

They should file a 1040 or 1040-SR form instead.

Hence, Option A is correct, No, partly because they will be able to claim a dependent.

A pack of six cans of coffee cost 12$ . How much would 15 cans of coffee cost

Answers

$30 because 12/6 = 2 so 15 x 2 = 30

The cost for 15 cans of coffee is found by first determining the cost per single can, which is $2, and then multiplying this cost by the number of cans, resulting in a total of $30 for 15 cans.

To calculate the cost of 15 cans of coffee when a pack of six cans costs $12, we first need to find the cost of a single can. To do this, we divide the cost of the pack by the number of cans in the pack:

Cost per can = Total cost of the pack / Number of cans in the pack

Cost per can = $12 / 6 = $2

Now that we know the cost of one can, we can calculate the cost for 15 cans:

Total cost for 15 cans = Cost per can * Number of cans

Total cost for 15 cans = $2 * 15 = $30

Find the length of the chord of a circle of radius 100 feet subtended by an angle of 75◦ ?

Answers

1. By definition, the chord of a circle is a segment that joins the two points of an arch and if it passes through the center of the circle, is called "diameter". There is a formula that you can use to find the chord lenght. This is:

Chord lenght=2rSin(A/2)

2. Let's convert the angle from degrees to radians:

75°π/180°=5π/12

3. So, you have:

r: It is the radius of the circle (r=100 feet).
Sin: It is the sine function.
A: It is the angle subtended at the center by the chord (A=5π/12).

4. When you substitute these values into the formula (Chord lenght=2rSin(A/2)), you obtain the chord lenght:

Chord lenght=2rSin(A/2)
Chord lenght=2(200 feet)(Sin(5π/12/2))

5. Therefore lenght of the chord is:
Chord lenght=18.2706 feet

At middle ave school 1/3 of the students are on the track team.the track coach offered to buy a pizza or subs for everyone on the team.of the students for whom the coach bought good 3/5 ordered pizza.what fraction of the students at middle ave school atenpizza

Answers

Final answer:

To determine how many students at Middle Ave School ate pizza, multiply the fraction on the track team (1/3) by those who ordered pizza (3/5), which equals 3/15 or simplified to 1/5 of the students.

Explanation:

To find out what fraction of the students at Middle Ave School ate pizza, you need to multiply the fractions that represent the students on the track team and those who ordered pizza. Initially, we know that 1/3 of the students are on the track team. Of these students, 3/5 ordered pizza. Multiplying these two fractions gives us the fraction of the entire student body that ordered pizza.

To multiply fractions, you multiply the numerators together and then the denominators together. So, for this problem, you'd multiply 1 by 3 to get the numerator, and then 3 by 5 to get the denominator:

1/3 * 3/5 = 3/15

But 3/15 can be simplified by dividing both the numerator and the denominator by their greatest common divisor, which is 3:

3/15 = 1/5

Therefore, 1/5 of the students at Middle Ave School ate pizza.

Ms.jones has a decorative pyramid that sits on her fireplace mantle .the base is an equilateral triangle with an area of 6 square inches. The height of the pyramid is 15 inches. What is the volume?

Answers

The volume is given by
.. V = (1/3)Bh
Fill in the given values and do the arithmetic.
.. V = (1/3)(6 in^2)*(15 in)
.. V = 30 in^3

The volume is 30 cubic inches.

Final answer:

To find the volume of Ms. Jones's pyramid with an equilateral triangle base area of 6 square inches and a height of 15 inches, we use the volume formula for a pyramid, V = [tex]\frac{1}{3}[/tex] × base area × height, resulting in a volume of 30 cubic inches.

Explanation:

To calculate the volume of the pyramid, we use the formula for the volume of a pyramid which is V = [tex]\frac{1}{3}[/tex] × base area × height. The base of Ms. Jones's decorative pyramid is an equilateral triangle with an area of 6 square inches, and the pyramid's height is 15 inches. First, we need to find the volume using the given base area and height.

Substituting the values into the formula, we get:

V = [tex]\frac{1}{3}[/tex] × 6 in² × 15 in

V = 2 in² × 15 in

V = 30 in³

Therefore, the volume of Ms. Jones's pyramid is 30 cubic inches.

Answers

I did most of it for you-
Volume of the cone is 13.1
Volume of the cylinder is 18.9
Now, you just subtract two of the flat circular surfaces, because the two shapes are attached, therefore those parts are not surface area. And there is your answer.

The surface area is calculated based on the surfaces which are visible from the outside. In this case, you only need to calculate the surface of lateral side on the cone, the surface of lateral side on the cylinder, and the circle on the lower base of cylinder.

Write the expression to find the surface area
sa = lateral side of cone + lateral side of cylinder + circle
sa = (π × r × s) + (2 × π × r × t) + (π × r²)

Input the numbers
sa = (π × 1 × 3) + (2 × π × 1 × 2) + (π × 1²)
sa = 3π + 4π + π
sa = 8π
sa = 8 × 3.14
sa = 25.12

to the nearest tenth
sa = 25.1

What is Equation Modelling?

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

Given is taxi company charges a flat fee of $3.00 for using the taxi and $0.75 per mile.

PART - A

Assume that [x] represent the number of miles and [y] represent the total cost. Therefore, the equation that you could use to find the cost of the taxi ride in Baltimore can be written as-

y(x) = 0.75x + 3

y(x) = 3x/4 + 3

PART - B

For [x] = 8 miles, the total cost will be -

y(8) = (3 x 8)/4 + 3

y(8) = 6 + 3

y(8) = 9

For 8 miles of travel, the total cost would be $9.

PART - C

For a total fare of $15 -

15 = 3x/4 + 3

12 = 3x/4

x = (12 x 4)/3

x = 16

For a total fare of $15, we can ride for 16 miles.

Therefore -

The equation to find the cost will be y(x) = 0.75x + 3 For 8 miles of travel, the total cost would be $9.For a total fare of $15, we can ride for 16 miles.

As we know it is an isosceles triangle. So, the base can be divided equally in 2 parts for both triangles.

So, we can take the hypotenuse as 29 inches and base as 20 inches.

Now applying Pythagoras theorem, we get;

[tex]29^{2} =20^{2} +x^{2}[/tex]

[tex]841=400+x^{2}[/tex]

=>[tex]841-400=x^{2}[/tex]

[tex]x=\sqrt{441}[/tex]

x=[tex]\sqrt{3*7*3*7}[/tex]

=> [tex]x=21[/tex]

Hence, the height is 21 inches.

Give a big-o estimate for the number of operations (where an operation is an addition or a multiplication) used in this segment of an algorithm. t := 0 for i := 1to3 for j := 1to4 t := t + ij

Answers

We have a "rectangular" double loop, meaning that both loops go to completion.
So there are 3*4=12 executions of t:=t+ij.

Assuming two operatiions per execution of the innermost loop, (i.e. ignoring the implied additions in increment of subscripts), we have 12*2=24 operations in all.

Here the number of operations (+ or *) is exactly known (=24).

Big-O estimates are used for cases with a varying scale of operations, governed by a variable (usually n) to indicate the sensitivity of the number of operations relative to a change in the size of n.

Here we do not have a scale, nor n is defined. The number of operations is constant and known at 24. So a variable is required to find the big-O estimate.
