Rob can mop a warehouse in 10 hours. Maria can mop the same warehouse in 11 hours. Find how long it would take them if they worked together.

Answers

Answer 1
The answer would be 21 good luck hope you get it correct
Answer 2

Answer:

It would take them  [tex]\frac{110}{21}[/tex] or approximately 5.24 hours together

Step-by-step explanation:

Use the algebra work formula, [tex]\frac{1}{tb}[/tex] = [tex]\frac{1}{t1}[/tex] + [tex]\frac{1}{t2}[/tex], where tb is the time together, t1 is the time of one person individually, and t2 is the time of the other person.

Plug in 10 and 11:

[tex]\frac{1}{tb}[/tex] = [tex]\frac{1}{t1}[/tex] + [tex]\frac{1}{t2}[/tex]

[tex]\frac{1}{tb}[/tex] = [tex]\frac{1}{10}[/tex] + [tex]\frac{1}{11}[/tex]

Find the common denominator, then add the fractions together:

[tex]\frac{1}{tb}[/tex] = [tex]\frac{11}{110}[/tex] + [tex]\frac{10}{110}[/tex]

[tex]\frac{1}{tb}[/tex] = [tex]\frac{21}{110}[/tex]

Cross multiply and solve for tb:

110 = 21tb

5.24 = tb

So, it would take them [tex]\frac{110}{21}[/tex] or approximately 5.24 hours together

A traingle has coordinates at A(-2,0) B(-4,4) and C(1, 6). What are the new locations of the coordinates after a dilation by a scale factor of 4?

Answers

Answer: A (-2,0) --> (-8,0)

B(-4,4) --> (-16,16)

C(1,6)--> (4,24)

Step-by-step explanation:

Multiply each coordinate by 4

A (-2,0) --> (-8,0)

B(-4,4) --> (-16,16)

C(1,6)--> (4,24)

The new locations of the coordinates after dilation by a scale factor of 4 as

A (-2,0) ⇒ (-8,0)

B(-4,4) ⇒ (-16,16)

C(1,6) ⇒ (4,24)

What is dilation?

Dilation is a process for creating similar figures by changing the size.

What is a graph?

A graph can be defined as a pictorial representation or a diagram that represents data or values.

As we know dilation factor is the ratio of sides in the original image and the image after dilation.

Dilation factor = 4

Multiply each coordinate by 4

A(-2,0) ⇒ (-8,0)

B(-4,4) ⇒ (-16,16)

C(1,6) ⇒ (4,24)

Answer:

B!

Step-by-step explanation:When you distribute the 3 among the x and 1 you will get 3x+3.

You'd add that three to the five and then end with

y= 8x+3

B - y(8x + 3)

Simplify y=3(x+1) + 5x
y = 3x+3+5x
y = 8x+3

A community theater uses the function p(d)= -5d²+300d -200 to model the profit (in dollars) expected in a weekend when the tickets to a comedy show are priced at d dollars each: Part A: Write and solve an equation to find out the prices at which the theater would earn $2,300 in profit from the comedy show each weekend. Show your reasoning Part B: At what price would the theater make the maximum profit. and what is that maximum profit? Show your reasoning.​

Answers

Answer:

A. $66.33B. $4300

Step-by-step explanation:

Given function:

p(d)= -5d² + 300d - 200 Part A

p(d) = 2300, find d:

2300 = -5d² + 300d - 200 5d² - 300d + 200 - 2300 = 05d² - 300d - 2100 = 0d² - 60d - 420 = 0d²- 2*30d + 900 = 1320(d - 30)² = 1320d- 30 = √1320d = 30 + 36.33d = 66.33 Part B

Maximum point of the function is obtained at vertex, which is (x = -b/2a):

d = - 300/-10 = 30

The maximum profit is:

p(30) = -5(30)² + 300(30) - 200 = 4300

Find the value or measure. Round answers to the nearest tenth, as needed.

Write the equation of the line in slope-intercept form for the line with a slope of 13 and a y - intercept of (0, 4)

Answers

Answer:

y=13x+4

Step-by-step explanation:

y-y1=m(x-x1)

y-4=13(x-0)

y-4=13(x)

y-4=13x

y=13x+4

Answer:

y=13x + 4

Step-by-step explanation:

Hi there!

We want to write the equation of the line in slope-intercept form.

Slope-intercept form is given as y=mx+b, where m is the slope and b is the value of y at the y intercept

We are given that the line has a slope of 13, and a y intercept of (0,4)

As we are directly given the slope and the y intercept, we can substitute these values into the formula to find the equation of the line

First, substitute 13 as m

y=13x + b

Now, as stated earlier, the value of b is the value of y at the y intercept.

We were given that the y intercept is (0,4); the value of y at this point is 4

Substitute 4 as b into the equation

y=13x + 4

Hope this helps!

Trevor pet goat weighed 6 3/ pounds when oit was born. By age 3 the goat weighted 8 times as much. Fill in each box with a number or sysmobe to answer tthis question.

Answers

Answer: 51 pounds

Step-by-step explanation:

Since the goat weighed 6 3/8 pounds and weighed 8 times as much by age 3, the weight of the goat at age 3 will be gotten by multiplying 6 3/8 by 8. This will be:

= 6 3/8 × 8

We change 6 3/8 to an improper Fraction

= 51/8 × 8

= 51 pounds

The weight is 51 pounds
