How many total hours did the girls spend cleaning their home

9514 1404 393

Answer:

Step-by-step explanation:

The effort required to complete a task is often estimated in terms of person·days. Amy's barn-building task takes an effort of ...

  (5 workers)(9 days) = 45 worker·days

If there are only 3 workers, the time required is ...

  time = (45 worker·days)/(3 workers) = 15 days

__

If the barn is to be build in 7 days, the number of workers required is ...

  (45 worker·days)/(7 days) = 6 3/7 workers

A minimum of 7 workers are required to build the barn in 7 days or less. (6 workers will take 7 1/2 days, so aren't enough.)

Answer:

$8.26

Step-by-step explanation:

$48.75= Total

$1.50= Coupon discount

5= Number of Sets bought by Mrs. James

*$48.75-($1.50*5)= $41.28*

41.28= Total after Coupon discount is removed

5= Number of Sets bought by Mrs. James

$41.28/5= $8.256

Answer:

There are at least 111 rose blooms in May's Garden.

Answer:

y + 1 = (1/2)(x - 3) - point-slope form

OR

y = (1/2)x - 5/2 - slope-intercept form

Step-by-step explanation:

Given a slope and point, use point-slope form to write the equation for the line:

y - y1 = m(x - x1)

(x1, y1) is the point given and m is the slope.

y - (-1) = (1/2)(x - 3)

y + 1 = (1/2)(x - 3)

If you need to rewrite in slope intercept form, you can do so by distributing the 1/2 to the x - 3 and subtracting 1 from both sides:

y + 1 = (1/2)x - 3/2

y = (1/2)x - 5/2

Answer:

[tex]\boxed {\boxed {\sf y= \frac {1}{2}x - \frac {5}{2}}}[/tex]

Step-by-step explanation:

The equation of a line can be found using the point-slope formula.

[tex]y-y_1=m(x-x_1)[/tex]

where m is the slope and (x₁, y₁) is the point the line passes through. For this line, the slope is 1/2 and the point is (3, -1). Therefore,

[tex]m= \frac {1}{2} \\x_1= 3 \\y_1= -1[/tex]

Substitute the values into the formula.

[tex]y--1= \frac {1}{2}(x-3)[/tex]

[tex]y+1= \frac {1}{2}(x-3)[/tex]

The equation can be left like this, or put into slope-intercept form (y=mx+b).

First, distribute the 1/2. Multiply each term inside the parentheses by 1/2.

[tex]y+1= \frac {1}{2}x - \frac {3}{2}[/tex]

Next, subtract 1 from both sides of the equation.

[tex]y+1-1= \frac {1}{2}x - \frac {3}{2}-1[/tex]

[tex]y= \frac {1}{2}x - \frac {5}{2}[/tex]

Answer:

2x= 40°

5x= 100°

Step-by-step explanation:

2x on opposite angle because it is an isosceles triangle

2x+ 2x+ 5x = 180° (angles of a triangle)

9x= 180

x= 180/9

x= 20°

Sub

2(20)= 40°

5(20)= 100°

0.5 is the value of 2.5 by 5.

A division is a process of splitting a specific amount into equal parts.

We need to find the solution when 2.5 divided by 5.

2.5/5

2.5 is the numerator and 5 is the denominator.

5 is the divisor and 2.5 is the dividend.

Zero point five is the value of 2.5 by 5.

0.5 is the value of 2.5 by 5.

Hence, 0.5 is the value of 2.5 by 5.

Answer:

y = 72

Step-by-step explanation:

Joint proportion is given by the expression;

y = kxz

Given the following values;

y = 75, x = 5 and z = 5

To find the constant, k;

75 = k*5*5

75 = 25k

k = 75/25

k = 3

Next, we find the value of y when x = 4 and z= 6

y = kxz

y = 3*4*6

y = 72
