Which polynomial is in standard form?

Answer:

A

Step-by-step explanation:

Answer:

y = 9/4x.

Step-by-step explanation:

According to slope-intercept form, y = mx + b where m is the slope and b is the y-intercept.

So, y = 9/4x + 0

y = 9/4x.

Hope this helps!

The required equation of the line is given as 9/4x with a slope of 9/4 and a y-intercept of 0.

Given that,
The linear equation represents a line with a slope of 9/4 and a y-intercept of 0 is to be determined.

The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.

here,
Standard equation of the line,
y = mx + c
Put , = 9/4 and c = 0
y = 9/4x + 0
y = 9/4x

Thus, the required equation of the line is given as 9/4x.

The sum of the arithmetic series

[tex]S_{n} = \frac{n}{2} (2 a + (n-1) d)[/tex]

Step-by-step explanation:

Explanation

Let  a , a+d , a+2 d , ..........a+(n-1)d +....... is an arithmetic sequence

The sum of the sequence is called arithmetic series

The [tex]n^{th}[/tex] term of the sequence

[tex]t_{n} = a + (n-1) d[/tex]

The sum of the arithmetic series

[tex]S_{n} = \frac{n}{2} (2 a + (n-1) d)[/tex]

Here 'a' is the first term of the sequence

and 'd' be the difference between two values

sum of first term

put n=1  ⇒  [tex]S_{1} = a[/tex]

Put n =2 ⇒ [tex]S_{2} = \frac{2}{2} (2 a + (2-1)d)[/tex]

                  [tex]S_{2} = 2 a + d[/tex]

......and so on

Answer:

y = 5/6x +1

Step-by-step explanation:

5x - 6y = -6

We want the equation in the form

y = mx+b where m is the slope and b is the y intercept

Subtract 5x from each side

5x -5x - 6y =-5x -6

-6y = -5x -6

Divide each side -6

-6y/-6 = -5x/-6  -6/-6

y = 5/6x +1

Step-by-step explanation:

Answer:

a) Area of wall to be painted = 114 sq ft

b) Number of cans required = 2×5 = 10

c) Total cost of paint = $338.43

Step-by-step explanation:

We are asked to find the area of wall that needs to be painted.

we need to subtract the area of window from the area of wall.

We know that area of a rectangular shape is given by

Area = Width×Length

Area of whole wall = 8×15 = 120 sq ft

Area of window = 2×3 = 6 sq ft

Area of wall to be painted = 120 - 6 = 114 sq ft

1 can of paint will cover 25 sq ft of area.

So to cover the area of wall to be painted,

114/25 = 4.56

since number of cans cannot be in fraction so we would need 5 cans

Since two coats of paints are needed so

Number of cans required = 2×5 = 10

1 can of paint costs $29.95

We have total 10 cans

$29.95×10 = $299.5

There is also a 13% tax so the total cost is

$299.5×0.13 = $38.93

Total cost of paint = $299.5 + $38.93

Total cost of paint = $338.43

Answer:

5:4

Step-by-step explanation:

In Mrs. Nathan's class,  the ratio of girls to boys is 5:4.

The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects.

Given, In Mrs. Nathan's class, there are 16 boys and 20 girls.

the ratio of girls to boys = 20/16

the ratio of girls to boys = 5/4

Therefore, the ratio of girls to boys in Mrs. Nathan's class is 5: 4.

Answer:

1. 47 correct, 0 wrong and 3 unanswered

2. 48 correct, 1 wrong and 1 unanswered

Step-by-step explanation:

Given;

Total number of questions = 50

For correct answers = 2

For wrong answers = -2

Unanswered questions = 0

Yash scored 94 marks

Let c, w and u represent the number of correct, wrong and unanswered questions

2×c - 2 × w + 0×u = 94

2c -2w = 94 .....1

And;

c + w + u = 50 .....2

We have 2 equations and 3 unknowns

By observing the problem, we can see two possible solutions;

Case 1: Assuming he did not miss (get wrong) any answer;

He needs to score 47 answers right;

47 × 2 = 94

Then;

c = 47 w = 0 and u = 50 - (47+0) = 3

47 correct, 0 wrong and 3 unanswered

Case 2: Assuming he got one answer wrong;

He would need to score one more answer right compared to the first case;

(47+1) × 2 - 1 × 2 = 96 - 2 = 94

c = 47+1 = 48

w = 1

u = 50 - (48+1) = 1

So he need to score 48 correct answers, 1 wrong answer and 1 unanswered.

answer: $1,012.50

Step-by-step explanation:

12.5 ÷ 100 = 0.125

0.125 × 800 = 100

800 + 100= 900 ( half-yearly interest)

0.125 × 900 = 112.5

900 + 112.5 = $1,012.50 ( end of first year interest)

Answer:

Step-by-step explanation:

Let's write a system.

Let's say that the variables are x and y.

xy=48

x+y=14

Solve for one of the variables, let's say, x.

x=14-y.

Now substitute x into the 1st equation.

(14-y)y=48

Simplify.

-y²+14y=48

Make it into a quadratic equation.

-y²+14y-48=0

Make sure y²'s coefficient is one. Divide everything by -1

y²-14y+48=0

Now factor!

What factors add up to 14 and multiply to 48.

6 and 8!

Since the 2nd term is negative, and the 3rd term is positive, the factors have to be negative.

y²-6y-8y+48=0

Group.

(y²-6y)+(-8y+48)=0

y(y-6)-8(y-6)=0

(y-8)(y-6)=0

y-8=0

y-6=0

y=8 y=6

now let's substitute each y value into y²-14y+48=0

8²-14(8)+48=0

64-112+48=0

0=0. so y=8 checks out!

6²-14(6)+48=0

36-84+48=0

0=0 so y=6 also checks out!

Choose one y value and solve for x, in each equation :

xy=48

x+y=14

8x=48

x+8=14

x=6

x=6

It checks out!

so the factors are

x=6 y=8.

Answer:

311 pounds

Step-by-step explanation:

Here, we are to calculate the average weight of the upper-class men offensive players

To calculate this, we need to sum up all the weights and divide by their count

Mathematically, that would be;

Average weight = (322+290+321+326+330+315+311+292+290)/9 = 2,797/9 = 310.77778

Now this written in 3 significant figures would be 311 pounds

Answer:

311

Step-by-step explanation:

You add all of the numbers first (2797)

Then you divide by how many numbers there were (9)

You get 310.7778

Then you round with 3 sig figs.

That is 311

Answer:

30⁰ , 60⁰ , 90⁰

Step-by-step explanation:

Let the angles x , 2x , 3x

By angle sum property:

x + 2x + 3x = 180⁰

6x = 180⁰

x = 30⁰

Angles are : 30⁰ , 60⁰ , 90⁰

Answer:

30°, 60°, 90°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the parts of the ratio, 1 + 2 + 3 = 6 parts

Divide to find the value of one part of the ratio

180° ÷ 6 = 30° ← value of 1 part of the ratio, thus

2 parts = 2 × 30° = 60°

3 parts = 3 × 30° = 90°

Thus angles are 30°, 60° and 90°
