grandymaker [24]4 years ago
4 0

Answer:

Step-by-step explanation:

Indirect proportion. If no. of workers increased, the working days will be decreased.

No: workers to complete in 16 days = 20 * 12 /16 = 5 * 3 = 15 workers

3 more workers should be added to complete the work in 16 days​

What is the area in square meters of 6 triangles. how many triangles are needed to compose a region that is 1 1\2 square meters?
Delicious77 [7]

To create an area that is 1.5 m^2   in size, you will need to make use of a total of 27 triangles.

<h3>How many triangles are needed to compose a region that is 1.5 square meters?</h3>

A square that has a size of one square meter is divided into nine smaller squares that are similar to each other. Each of the little squares is divided into two triangles that are similar to one another.

There are nine smaller squares contained inside one square meter, since 1 square meter may be broken down into nine identical smaller squares. Each of the little squares is divided into two triangles that are similar to one another. 9 smaller squares may be broken down into the following:

9*2=18 (shows identical triangles)

Hence, 1 square meter is decomposed into 18 identical triangles.

We need to find the number of triangles needed to compose a region that is square meters

where

m^2 = 1.5 m^2

Where

1 m^2 = 18 identical triangles.

1.5 m^2 = 1.5 * 18

1.5 m^2  = 27 identical triangles.

In conclusion, To create an area that is 1.5 m^2   in size, you will need to make use of a total of 27 triangles.

Answer:

231/8 simplified is 28 7/8

Step-by-step explanation:

first you have to convert all mixed fractions into improper fractions so 8 1/4 will become 33/4 and 3 1/2 will become 7/2 and then just multiply and you get 231/8 which simplified is 28 7/8

I need to find x and y and also find the measure of angle x and angle y and find the measure of angle (3y+4)
Elenna [48]
We can find angle STN through sum of angles in a triangle.
180 - 90 - 32 = 59 degrees.

Therefore, x is 59 degrees because they are alternate angles, indicated by the Z shape.

We can work out angle MNT by sum of angles in a line.
180 - 59 = 121 degrees.

3y + 4 = 121
3y = 117
y = 39

Write the equation of the line that passes through the given point and is perpendicular to the given line. Your answer should be
kvasek [131]

Answer:

y = 7x/8 - 53/8

Step-by-step explanation:

P(3,-4)

x = -7y/8 + 3

Isolate y and translate to slope-intercept form:

y = mx + b

x = -7y/8 + 3

x - 3 = -7y/8

8x - 24 = -7y

y = -8x/7 - 24/7

The slope of the equation is -8/7

The slope of the new equation will be perpendicular to the slope of the given equation which means it is the negative reciprocal.

y = mx + b where m = -1/(-8/7) = 7/8

y = 7x/8 + b

Plug in know values and solve for b:

-4 = 7(3)/8 + b = 21/8 + b

-4 - 21/8 = b

b = -32/8 -21/8 = -53/8

Plug in b into the equation:

y = 7x/8 - 53/8
