A new housing development will have 105 houses. All the houses have the same floor plan and dimensions. Carlos can paint a house by himself in 4
days. Manuel can paint a house in 3 days.
A normal workweek is 5 days how many weeks would it take them to work together to paint 105 houses?
now suppose that they need to finish in 28 weeks but only have enough to pay for one extra crew member. What is the greatest number of days the third
worker can take to paint each house?

They are both obtuse and number 5 is 130% and number 6 is 110%

Answer:

The dimension of the rectangle are [tex]9\cdot x - 2\cdot y[/tex] units and [tex]9\cdot x + 2\cdot y[/tex] units, respectively.

Step-by-step explanation:

Geometrically speaking, the area of a rectangle is equal to the product of its base and its height. If we know that area of the figure is [tex]81\cdot x^{2} - 4\cdot y^{2}[/tex] square units, then we proceed to factor the expression:

1) [tex]A = 81\cdot x^{2} - 4\cdot y^{2}[/tex] Given

2) [tex]A = (9\cdot x -2\cdot y)\cdot (9\cdot x + 2\cdot y)[/tex] [tex]a^{2} - b^{2} = (a + b) \cdot (a - b)[/tex]/Result

The dimension of the rectangle are [tex]9\cdot x - 2\cdot y[/tex] units and [tex]9\cdot x + 2\cdot y[/tex] units, respectively.

Answer:

(9x + 2y)(9x - 2y)

Step-by-step explanation:

The rule: a^2 - b^2 = (a + b)(a - b)

81x^2 - 4y^2  

And we have a = 9x and b = 2y

and our factors are.

(9x + 2y)(9x - 2y)

so the the dimensions are 9x + 2y and 9x - 2y

Answer:

2) Slope=10/3

Step-by-step explanation:

2. Use the equation y2-y1/x2-x1. In this line, I took the points (-4,-5) and (-1,5). Plug this into the equation to get 5--5/-1--4. Simplify this to get 5+5/-1+4. Simplify this to get 10/3. Therefore, the slope is 10/3

4. The equation is y=mx+b where m is the slope and b is the y-intercept. This means that the equation will be 8/3x-5.

Step-by-step explanation:

if diego car can hold 14 gallons and eveery day they use 0.6 0.6x25 is 15 which means that they can drive 15 days in all so 15-1.5 13.5 so they can only drive for 13.5 days

hope this helps :)

Answer:

No, Diego's family cannot drive the car for 25 days without the warning light coming on.

Step-by-step explanation:

Find how much fuel they will use in 25 days by multiplying 25 by 0.6, since the car uses 0.6 gallons each day:

25(0.6)

= 15

Subtract this from 14 to see how much fuel will remain, starting from a full tank:

14 - 15

= -1

The number is negative, meaning that driving the car for 25 days will use up all of the fuel. So, the warning light will come on.

No, Diego's family cannot drive the car for 25 days without the warning light coming on.

Answer:

The fifth term is the middle term of nine, with coefficient given by all the ways of choosing  4  items out of  8 , namely the ways of choosing  4   a 's out of  8  binomial factors.

Step-by-step explanation:

The third term of the expansion is 56a⁵b³

The expression is given as:

(a + b)^8

The above expression is a binomial expression, and the nth term of the expression is:

(a + b)^n = nCr * a^(n - k) * (b)^k

Where k = 0, 1, 2.....

So,we have:

(a + b)⁸ = ⁸C₃ * a⁸⁻³ * b³

Evaluate the combination expression

(a + b)⁸ = 56a⁵b³

Hence, the third term of the expansion is 56a⁵b³

Answer:

1, 6, 11, 16, 21, 26, 31, 36, 41, 46, 51, 56, 61, 66, 71.

The area of the figure = area of trapezium + area of rectangle = 420 cm².

Area of trapezium = 1/2(a + b)h

Area of rectangle = length × height.

The area of the figure = area of trapezium + area of rectangle

The area of the figure = 1/2(a + b)h + length × height

Plug in the values

The area of the figure = 1/2(23 + 15)6 + 23 × 12

The area of the figure = 144 + 276

The area of the figure = 420 cm²

Answer: The area is 390 cm

Step-by-step explanation:

All you have to do is find the area of the trapezoid and the area of the rectangle and add them together.

Area of trapezoid formula: A = 1/2 (Base 1 + Base 2)h

base 1 = 15 cm

base 2 = 23 cm

height = 6 (18-12)

so, 15 + 23 = 38

38 x 6 = 228

228 x 0.5 or 1/2 = 114

Therefore the area of the trapezoid is 114 cm

Area of rectangle formula: A = bh

base = 23

height = 12

12 x 23 = 276

Therefore the area of the rectangle is 276 cm

Now add the values together, 114 + 276 = 390

390 is the area of the figure

To fins the area if the rectangle you need to find the hypotenuse of the triangles, which are equal. so 10.4 squared plus 15.3 squared is 342.25, and the square root is 18.5.

Then, 18.5 multiplied by 7 is 129.5. Then to fins the area of a triangle you need to do it like a rectangle but in this case, sense there are 2, then just find the area. 129.5+(10.4 times 15.3=159.12)=129.5+159.12=288.62

Answer:

The mean is the best choice because the data is nearly symmetrical

Step-by-step explanation:

Question:

The data from the dot plot obtained from another post of the question are;

[tex]\begin{array}{ccc}Strokes \ Required&& Number \ of \ Players\\1&&2\\2&&3\\3&&4\\4&&5\\5&&5\\6&&3\\7&&2\\8&&\\9&&1\end{array}#[/tex]

From the given data, we have that the mean of the 25 players is 4.24

Mean = 4.24 strokes

The median strokes is 4.5 strokes

Median = 4.5

The values of the mean and median are approximately equal because the data are symmetrical and has the normal shape

Therefore, the mean is the best option due to the symmetrical shape of the data.

A) The mean is the best choice because the data is nearly symmetrical
