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:

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

The sum of the  arithmetic series

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

Answer:

Correct option: Second one -> 141.3 cm3

Step-by-step explanation:

The volume of "snow" is the sum of the half sphere volume and the cone volume.

The volume of the half-sphere is given by the formula:

V = (2/3) * pi * radius^3

If the half sphere has a radius of 3 cm, we have that:

V1 = (2/3) * pi * 3^3 = 56.5 cm3

The volume of the cone is given by:

V = (1/3) * pi * radius^2 * height

If the radius is 3 cm and the height is 9 cm, we have:

V2 = (1/3) * pi * 3^2 * 9 = 84.8 cm3

So the final volume is:

V = V1 + V2 = 56.5 + 84.8 = 141.3 cm3

Correct option: Second one

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.

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.

[tex]E(n)=75000 \times 2^n[/tex]

Complete question:

write a function that gives mapiyas cumulative earnings E(n), in dollars when she has written n sequel's

Step-by-step explanation:

According to the question, she earned $75000 for the first book.

Also,We are  given that her cumulative earnings double with each sequel that she writes.

Assuming she has written n sequel's

Now since we are given that her cumulative earnings double with each sequel

So, her initial earning will be [tex]2^n[/tex] times

So, her earning will be : [tex]75000 \times 2^n[/tex]

Now we are given that cumulative earnings is denoted by E(n)

So, the function becomes :[tex]E(n)=75000 \times 2^n[/tex]

Hence a function that gives Mapiya's cumulative earnings E(n), in dollars when she has written n sequel's  is  [tex]E(n)=75000 \times 2^n[/tex]

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

The measure of angle BOC is 42 degrees.

Answer:

BOC = 42º

Step-by-step explanation:

Angle BOC is equal to 42 degrees, due to these steps -

1. Create the equation which will result to be -

6x - 6 + 5x + 8 = 90

2. Simplify by adding variables and numbers together -

11x + 2 = 90

3. Subtract 2 from both sides to get -

11x = 88

4. Divide by 11 on both sides to get-

x = 8

5. Substitute x in angle BOC as 8 to get this equation -

6(8) - 6

6. Solve

48 - 6 =

42º

Your final answer for angle BOC is 42º!

Answer:

The overall change in temperature over the time period ∆T = -12.6°F

Step-by-step explanation:

Rate of change of temperature r = -2.8°F per hour

Time t = 4.5 hours

The overall change in temperature ∆T = Rate of change of temperature × time period

∆T = r × t

∆T = -2.8°F per hour × 4.5 hours

∆T = -12.6°F

The overall change in temperature over the time period is -12.6°F

Answer: -12.6

Step-by-step explanation:

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
