A triangle has both its base and height reduced by a factor of one half. By what factor would the area of the triangle decrease?

Answer:

65 Degrees

Step-by-step explanation:

Answer:

X=65°

Step-by-step explanation:

Fine y =71°, alternate angle.

Find Z

71 °+ Z +65° =180°

136° + z= 180°

collect like team

Z=180°-136°

Z = 44°

Find X

Y + X + Z=180°

input the value of y and x

71° + X +44° =180°

115°+ X=180°

X = 180°-115°

X =65°

Answer:

28 strokes

Step-by-step explanation:

The computation is shown below:

It is given that the 42 strokes are required to fill up the 3 by 5th

So for completing the line, the number of additional strokes required is

But before the total strokes required is

= 42 × 5 ÷ 3

= 70

This represent the total

so, the additional strokes is

= 70 - 42

= 28 strokes

Answer:

The slope is equal to [tex]\frac{3}{4}[/tex].

Step-by-step explanation:

In order to solve this question we need to know that.......

[tex]m = \frac{y_{2}-y_{1} }{x_{2} - x_{1} }[/tex]

Where "m" = slope," [tex]y_{2}-y_{1}[/tex]" = first difference, and [tex]x_{2} - x_{1}[/tex] is the difference of the x values of the two points that we chose to fid the slope.

(If you don't understand something I would recommend to read about first differences and how we can use the first differences to find the slope).

Now we need to find two points on the line. One of them is already given to us and it is (36,27). In order to find the second one we will have to find a point with "x" and "y" values that have the same relation ship to each other as the point (36,27). We can do that by doing the following

[tex]\frac{x/a}{y/a} =\frac{x_{1} }{y_{1} }[/tex]

In this case a any common factor of "x" and "y" except 1. So now we can do the following...

[tex]\frac{36}{27} = \frac{36/9}{27/9} = \frac{4}{3}[/tex]

Now we know that another point on this line is (4,3).

Now all we have to imagine (36,27) as ([tex]x_{2} ,y_{2}[/tex]), and imagine (4,3) as [tex](x_{1} , y_{1})[/tex]. so now......

[tex]m = \frac{y_{2}-y_{1} }{x_{2} - x_{1} } = \frac{27 - 3}{36-4} = \frac{24}{32} = \frac{3}{4}[/tex]

Answer:

the answer is 7.

Step-by-step explanation:

here's why......if u place the 3 where a is it will become multiplication so that would be 2 times 3 minus b now but if u place -1 the minus becomes addition so it will be 6+1 which is 7.

Answer:

The value of expression when a=3 and b=-1 is 7

Step-by-step explanation:

Given expression is:

2a - b

Also given that

a = 3

b = -1

In order to find the value of the expression, we have to put 3 in place of a and -1 in place of b in the expression

So putting the values

[tex]=2(3)-(-1)\\=6+1\\=7[/tex]

Hence,

The value of expression when a=3 and b=-1 is 7

Answer:

  396,040

Step-by-step explanation:

Factors of 2020 are 2, 5, 101.

There are 1,000,000 / 1010 = 990 multiples of 2 and 5 and 101.

There are 1,000,000 / 505 -990 = 990 multiples of 5 and 101 only.

There are 1,000,000 / 202 -990 = 3,960 multiples of 2 and 101 only.

There are 1,000,000 / 10 - 990 = 99,010 multiples of 2 and 5 only.

There are 1,000,000 / 101 -990 -990 -3960 = 3,960 multiples of 101 only.

There are 1,000,000 / 5 -990 -990 -99,010 = 99,010 multiples of 5 only.

There are 1,000,000 / 2 -990 -3960 -99,010 = 396,040 multiples of 2 only.

So, the total number of multiples of any factor of 2020 is ...

  990 +990 +3960 +99,010 +3960 +99010 +396040 = 603960

Then the number of integers in the first million that do not share any common factors greater than 1 with 2020 is ...

  1,000,000 -603,960 = 396,040

Answer:

26 trees

Step-by-step explanation:

Ben, Cam, and Justin are lumberjacks. The number of trees they chop down is given by b+2c+3j where b is the number of hours Ben spends chopping, c is the number of hours Cam spends chopping, and j is the number of hours Justin spends chopping. How many trees do they chop down after Ben spends 8 hours chopping, Cam spends 3 hours chopping, and Justin spends 4 hours chopping?

Given:

b + 2c + 3j

Where,

b = number of hours Ben spends chopping

c = number of hours Cam spends chopping

j = number of hours Justin spends chopping

Substitute the below into the given expression

b = 8 hours

c = 3 hours

j = 4 hours

b + 2c + 3j

= 8 + 2(3) + 3(4)

= 8 + 6 + 12

= 26 trees

They chopped down 26 trees altogether

========================================================

Explanation:

Rule: The interior (inside) angles of a triangle always add to 180

K+L+M = 180

5x+9x+4x = 180

18x = 180

x = 180/18 ... divide both sides by 18

x = 10

That x value directly leads to...

As a check,

K+L+M = 50+90+40 = 180

This confirms we have the right x value.

--------------------------

We can further say,

note how interior angles K and L add to exterior angle LMN

50+90 = 140

This is an application of the remote interior angle theorem.

Answer:

Angle K = 50

Angle L = 90

Angle KML = 40

Angle LMN = 140

Step-by-step explanation:

Solve for x. We know that triangles' interior angles add up to 180.

So, we can set the values to equal to 180 and solve for x.

5x + 9x + 4x = 180

Simplify.

18x = 180

Now, divide by 18.

x = 10

Now, plug 10 in for each angle.

Angle K = (5 * 10) = 50

Angle L = (9 * 10) = 90

Angle KML = (4 * 10) = 40

For this last angle, we use the supplementary theorem that says "angles that are supplementary to each other add up to 180".

So, we do angle LMN + 40 = 180

Angle LMN = (180 - 40) = 140

Answer:

3 Lessons

Step-by-step explanation:

Find out the difference between the initial price of each lesson. In this equation it's $10. With that being said, for every lesson the difference will always be $10. So the next lesson would be a $20 lesson and so forth. By the third lesson the difference would be $30. You add the $30 to the $30 per lesson teacher and you'll get $90 which would be equal to the teacher doing it for $30 an hour to begin with.

The total number of lessons when the cost of the two teachers be the same is 3 and this can be determined by forming the linear equation.

Given :

The following steps can be used in order to determine the total number of lessons will the cost of the two teachers be the same:

Step 1 - Let the total number of lessons be 'x'.

Step 2 - The total amount of money the first piano teacher earn is:

= 20x + 30

Step 3 - The total amount of money another piano teacher earn is:

= 30x

Step 4 - According to the given data, the cost of the two teachers be the same, that is:

20x + 30 = 30x

Step 5 - Simplify the above equation.

30 = 10x

x = 3

Answer:

A=1, m=2, v=1

Step-by-step explanation:

A.

[tex]-15=-7a-4-4a\\\\-15+4=-11a-4+4\\\\-11=-11a\\\\a=1[/tex]

B.

[tex]m-4m=-6\\\\\\-3m=-6\\\\\\3m=6\\\\m=2[/tex]

C.

[tex]8v-3+3v=8\\\\11v-3=8\\\\11v-3+3=8+3\\\\11v=11\\\\v=1[/tex]

For A, I first subtracted -4 from -7 as their variables are the same. I cannot subtract integers from variables. Then, I added 4 on both sides to move the integer on the left side. (This would also remove the -4 on the right side because -4+4=0) Then I divided -11 by both sides to get 1a or a.

For B, I  subtracted -4 from 1 as their variables are the same. This time, since they are both negative numbers, I can make them both positive. So, just divide 3 by both sides as we want to get 1m.

For C, Add 3 to 8 as v is their variable. Then, I added 3 to both sides because we want to get the variable on one side. Divide by 11 and you will get v=1.
