Which of the following equations will produce the graph shown below?

Answers

Answer:

A. 6x^{2}+6y^{2}=144

Step-by-step explanation:

please help i dont understand

Answers

Given:

Number of spheres = 2

Number of prisms = 3

Number of pyramids = 5

To find:

The probability that a pyramid will be selected.

Solution:

We have,

Favorable outcomes = Number of pyramids

= 5

Total outcomes = Total number of figures

= [tex]2+3+5[/tex]

= [tex]10[/tex]

Now, the required probability is:

[tex]\text{Probability}=\dfrac{\text{Favorable outcomes}}{\text{Total outcomes}}[/tex]

[tex]\text{Probability}=\dfrac{5}{10}[/tex]

[tex]\text{Probability}=0.5[/tex]

Therefore, the probability that a pyramid will be selected is 0.5.

Don’t mind the random letters Fghhujhgdfvfdfgvee de f

Answers

Answer:

Step-by-step explanation:

Here, we want to graph the given line

Mathematically, to graph a line, we will

need to work with the intercepts

The general equation of a straight line is;

y = mx + b

is the slope and b is the y-intercept

with respect to the question, 4 is the y-intercept

we have this point as (0,4)

To get the x intercept, we will need to substitute 0 for the value of y

So, we have ;

0 = -x + 4

x = 4

The x-intercept too is 4

This is the point (4,0)

So by joining the points (0,4) and (4,0);

we have successfully graphed the line

It can be found as an attachment below

1.

Write the slope-intercept form of the equation for the line.

A. y = [tex]\frac{1}{2}[/tex]x - 1

B. y = – 2x – 1

C. y = 2x – 1

D. y = [tex]\frac{1}{2}[/tex]x + 1

Answers

Answer: Here is the answers after I graphed it

1: The equation of the line that has a slope of 1 and a y-intercept of -1 is:

y=1x-1.

...............................................................................................................................................

2: The equation of the line that has a slope of 1 and a y-intercept of -3 is:

y=1x-3.

Step-by-step explanation: I graphed it

1: You want to find the equation for a line that has a slope of 1 and a y-intercept of -1.

First of all, remember what the equation of a line is:

y = mx+b

Where:

m is the slope, and

b is the y-intercept

All you really have to do here is

replace m with 1, which is the slope you gave, and

replace b with -1, the y-intercept you gave,

in the equation y=mx+b.

The equation of the line that has a slope of 1 and a y-intercept of -1 is:

y=1x-1.

...............................................................................................................................................

2: You want to find the equation for a line that has a slope of 1 and a y-intercept of -3.

First of all, remember what the equation of a line is:

y = mx+b

Where:

m is the slope, and

b is the y-intercept

All you really have to do here is

replace m with 1, which is the slope you gave, and

replace b with -3, the y-intercept you gave,

in the equation y=mx+b.

The equation of the line that has a slope of 1 and a y-intercept of -3 is:

y=1x-3.

This meal costs $14.00.
A 7% sales tax is applied, followed by an automatic tip of 18%.
What is the total with tax and tip?

Answers

Answer:

17.6764$

Step-by-step explanation:

14 * 1.07 = 14.98$

14.98$ * 1.18 = 17.6764$

The tax is $0.98 and tip is $2.52

what is Unitary Method?

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Original Cost = $14

Tax = 7%

So, Price after tax = 14 + 7% of 14

= 14 + 0.98

= $14.98

and, after 18% tip = 14 + 18% of 14

= $16.52

Hence, the tax is $0.98 and tip is $2.52

area of shaded portion = 49.5 yd²____________________

Step-by-step explanation:

radius of circle = 5 yd ------ ( given )

height of triangle = 16 yd --- ( given )

base of triangle = 16 yd ----- ( given )

area of triangle = 1/2 × base × height

= 1/2 × 16 × 16

Answers

The graph is missing, so i have attached it.

Answer:

$0.40 per minute

Step-by-step explanation:

From the attached graph, we can see that it is a linear graph.

Thus, to find the unit rate paid by Ken, we will calculate the slope by picking two coordinate points with thick dots on the blue and calculating it.

Point 1 = (15, 6)

Point 2 = (35, 14)

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

Slope = (14 - 6)/(35 - 15)

Slope = 8/20

Slope = $0.40 per minute

It is estimated that at present less than half of the irrigation potential of India has been developed.If the high-yielding dwarf wheat and rice varieties are the catalysts that have ignited the green revolution, then chemical fertilizer is the fuel that has powered its forward thrust. The responsiveness of the high-yielding varieties has greatly increased fertilizer consumption. The new varieties not only respond to much heavier dosages of fertilizer than the old ones but are also much more efficient in its use. The old tall-strawed varieties would produce only ten kilos of additional grain for each kilo of nitrogen applied, while the new varieties can produce twenty to twenty-five kilos or more of additional grain per kilo of nitrogen applied. Consumption of nitrogen fertilizer in India has increased from fifty-eight thousand metric tons of nutrients in 19501951 to 538 thousand and 1.2 million metric tons in 19641965 and 19691970 crop cycles, respectively; and about sixty percent of this amount was produced domestically.Norman Borlaug, accepting the 1970 Nobel Peace Prize for his role in reducing hunger in India and PakistanHow is the position of farmers growing high-yield crops different from that of farmers growing traditional crops?Farmers growing high-yield crops use less land, causing them to follow a higher-density settlement pattern.Farmers growing high-yield crops are more likely to be self-sufficient and thus require less support from the rest of society.Farmers growing high-yield crops require a larger amount of water and are therefore restricted to land within the irrigated zone.Farmers growing high-yield crops require investment capital to fulfill their potential, but they can achieve profits and escape poverty.
