Step-by-step explanation:

Work finished by Francesca  in one hour = 1/6

Work finished by Irvin in one hour = 1/4

Work finished by Francesca and Irvin in one hour = 1/6 +1/4

                                                             [tex]=\frac{4}{24}+\frac{6}{24}\\\\=\frac{10}{24}\\\\=\frac{5}{12}\\[/tex]

5/12 of the work is completed by both in an hour

Whole work will be completed in 1*12/5 =12/5 hours = 2 2/5 hours

 (x -  (—— • x)) -  —  = 0  

        10          2

Simplify   1/2

        2          2

                   x = 9

Answer:

x = 9

Step-by-step explanation:

Firstly, you have to balance the equation.

Start by subtracting 0.5 from both sides. Remember, when solving algebraic equations such as this one, you use reverse PEMDAS, or SADMEP.

Now, you have 0.5x = 4.5

Now, for the next step: division. Divide both sides by 0.5, or in other words, multiply by 2.

x = 9

Answer:

On a coordinate plane, 2 curves intersect at (1, 1). One curve curves up and to the right from quadrant 3 into quadrant 1. The other curve curves down from quadrant 1 into quadrant 4

Step-by-step explanation:

The first function is given as:

[tex]log_3(x+3)[/tex]

The second function is given as:

[tex]log_{0.3}(x-1)[/tex]

First we graph both the functions.

We can see that one curves up and to the right from quadrant 3 into quadrant 1. This curve is of  [tex]log_3(x+3)[/tex]

The other curve curves down from quadrant 1 into quadrant 3

Both curves interest almost at (1,1)

Answer:

Step-by-step explanation:

You need to get w on one side by itself.

Start out by subtracting 2l from both sides.

p−2l=2w.

Now since w is being multiplied by 2 we need to divided both sides (all terms) by 2.

w=p2−I

Answer:

W=P-L

Step-by-step explanation:

P=2L+2W

Subtract 2L from both sides.

P-2L=2W

Divide both sides by 2

P-L=W

Answer:

The correct answer will be "1.60 hours".

Step-by-step explanation:

Within this test case, let's suppose that the bookstore had been closed on Sundays every other day while there were a total of 5 Sundays throughout the month of thirty days, thus effectively.

Months = 30

Number of sundays = 5

⇒  [tex]Effective \ working \ days = Months - Number \ of \ Sundays[/tex]

⇒                                          [tex]=30-5[/tex]

⇒                                          [tex]=25[/tex]

As we know, the total spend time will be 40 hours, then

⇒  [tex]Time \ spend \ each \ day = \frac{Total \ time \ spens}{Working \ days}[/tex]

On putting the estimated values, we get

⇒                                     [tex]=\frac{40}{30}[/tex]

⇒                                     [tex]=1.60 \ hours[/tex]

I think it would require 100 workers since 1 worker digs up 1 yard.

Hope this helps.

It is found that 100 workers are needed to dig a 100 yards long in 100 hours

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

We are given that Five workers dig a trench 5 yards long in 5 hours.

We need to find workers are needed to dig a 100 yards long in 100 hours.

5 workers dig , 5 yards long = 5 hours.

1 yards long = 1 hours.

Thus, 100 workers dig a 100 yards long in 100 hours.

Answer:

x = 19

Step-by-step explanation:

∠ 1 + ∠ 2 = 90° ( corresponding angle ), substitute values

4x + 9 + x - 14 = 90

5x - 5 = 90 ( add 5 to both sides )

5x = 95 ( divide both sides by 5 )

x = 19

The value of variable x is,

⇒ x = 19

We have to given that;

Measure of angles are,

m∠1 = (4x + 9)°

And, m∠2 = (x − 14)°

Now, We can see that,

Measure of angle 1 and 2 are complementary angle.

Hence, We get;

⇒ m ∠1 + m ∠2 = 90°

Substitute all the values, we get;

⇒ (4x + 9) + (x - 14) = 90

⇒ 5x - 5 = 90

⇒ 5x = 90 + 5

⇒ 5x = 95

⇒ x = 95 / 5

⇒ x = 19

Thus, The value of variable x is,

⇒ x = 19

Answer:

10/3 lawn

Step-by-step explanation:

2/3 of a lawn in 1/5 hour

-> 1 hour cab mow = 2/3(lawn) ÷ 1/5(hour)* 1(hour)

= 10/3 = 3,666666667 lawns

Answer:

maria can mow 3 lawns

Step-by-step explanation:

if it takes 1/5 of an hour to mown 2/3 of one lawn

60 divide by .2 = 12

that means it takes 12 miuntes to mown 2/3 of a lawn, so it takes 6 minutes for each 1/3

so 12+6= 18 minutes for one whole lawn

so 18 plus 18 equals 36

so 36 minutes for 2 lawns

then add another 18 minutes and you'll get 54 minutes. That's almost a whole hour

so Maria can mown 3 lawns

( if im wrong, im sorry i tried)

Answer:

It should be about 67%.

Step-by-step explanation:

The ratio 2:3 is the same as the fraction 2/3.

2 divided by 3 is equal to 0.66666...

When it is rounded to the hundredths place, it is 0.67.  

This means that the percentage is 67%.

Answer:

The enlarged object would be 150% larger, but the enlargement itself makes the new picture 50% larger than before as the previous size was already considered 100%.

Step-by-step explanation:

It is much easier to picture this with nice numbers.

Let's say you start with a paper that is size 100 (these numbers have no real meaning they are just for illustrating a point), this would be the 2 in the ratio so the equality would look like: [tex]\frac{2}{3}[/tex]=[tex]\frac{100}{x}[/tex]. At this point you can cross multiply and divide, getting 2x=300. By dividing by 2, you get x=150.

Now percents are out of 100, and you have one of those, only right now it is on the top. All you have to do is flip the fraction, you get [tex]\frac{150}{100}[/tex]=150% is how much it was enlarged when compared to the original, it got 1.5 times larger (you can flip the fraction because you are looking to see how much bigger it got in relation to the starting size).

However, if you are looking for only the enlargement as a percent of the total the answer would be 50% since the new size 150 is 50 larger than 100 and [tex]\frac{50}{100}[/tex]=50%.

Answer:

Correct option: first one -> y = (1/3)x + (10/3)

Step-by-step explanation:

The linear function that represents a line is:

y = ax + b

Where a is the slope and b is the y-intercept.

First we need to find the slope of the line that goes through (0, -3) and (3, -2).

Using both points, we can find the equation of the line:

x = 0 -> y = -3

-3 = a*0 + b

b = -3

x = 3 -> y = -2

-2 = 3a - 3

3a = 1

a = 1/3

The parallel line needs to have the same slope as the line, so we can model the parallel line with the following equation:

y = (1/3)x + b

The parallel line goes through the point (-4, 2), so we have:

x = -4 -> y = 2

2 = (1/3)*(-4) + b

b = 2 + (4/3)

b = 10/3

So the equation of the parallel line is:

y = (1/3)x + (10/3)

Correct option: first one

Answer:

24 units

Step-by-step explanation:

From the description:

We also know that

sin(a) = 4/5

From definition:

sin(a) = opposite/hypotenuse

Replacing:

4/5 = EF/DE

EF = (4/5)*DE

EF = (4/5)*30 = 24 units

The length of the segment EF of the triangle DEF is 24 units.

In the image attached below we summarize the triangle described in statement, by trigonometric relationship we find that the length of the segment EF is described by the following expression:

[tex]\sin a^{\circ} = \frac{EF}{DE}[/tex] (1)

If we know that [tex]DE = 30[/tex] and [tex]\sin a^{\circ} = \frac{4}{5}[/tex], then the length of the segment EF is:

[tex]EF = DE\cdot \sin a^{\circ}[/tex]

[tex]EF = 30\cdot \left(\frac{4}{5} \right)[/tex]

[tex]EF = 24[/tex]

The length of the segment EF of the triangle DEF is 24 units. [tex]\blacksquare[/tex]
