Answer:

Area: 27.5        trees?

Perimeter: 15    trees?

Step-by-step explanation:

Area of a right triangle is its base multiplied by its height

Since the two right triangles are mirror images of each other we only need to focus on one of them and then multiply our answers by 2

since the base of the whole triangle is halved we will do so to its value as well:

[tex]base=\frac{11}{2}[/tex]

we are given the height with the center line:

[tex]height=5[/tex]

so to get the area of one of the right triangles we do:

[tex]\frac{\frac{11}{2}*5}{2}[/tex]

and since there are two of them we can take away that divide by 2 to get:

[tex]\frac{11}{2}*5[/tex] which can be written as [tex]\frac{55}{2} ,\ 27\frac{1}{2} ,\ or\ 27.5[/tex]

now for the perimeter we just add up the outer most sides:

[tex]2+2+11=15[/tex]

(btw these measurements wouldn't make a triangle but that is what is shown so I just went with it)

Answer:

4 cm, if you subtract 9 from 13 you get four.

Answer:

at 12 hours, it's 9 inches.

at 14 hours, it's 14 inches.

at 13 hours it's 16 inches.

I'm not sure if you needed how many inches it snowed an hour, or if you just needed the hours and inches. My apologies.

Answer:

30

Step-by-step explanation:

Looking at the question we will notice that every 6 that Troy puts together Drake makes 10 so its simple, Troy makes 18 so we divide that by 6 meaning we get 3. We then get 3 and multiply it by 10, Thus 30 shall be our answer.

Answer:

55 degrees

Step-by-step explanation:

Complementary angles are two angles that equal 90 degrees together so if one angle is 35 degrees then the other must be able to add towards that to make 90 degrees

90=35+∠2

-35     -35

55=∠2

Answer:

It will be A

Step-by-step explanation:

M=140-100/5-3

m=40/2

m=20

Step-by-step explanation:

The dot is called a decimal point. It is also called the decimal separator. It separates whole numbers from fractional numbers.

In this example;

24.671

The numbers before the point, 24 is the whole number

The numbers after the point, 671 are the fractional portion of the number. They represent 6 tenths, 7 hundredths and 1 thousandths.

Also, the number of digits after the point tells you how many decimal place the number is in. In this example the number of decimal places is 3.

Answer:

1st answer is 6, 2nd is 5, 3rd is 5

Step-by-step explanation:

3x-2=x+10

3x-x=10+2

2x=12

x=12÷2

x=6

x+4=19-2x

x+2x=19-4

3x=15

x=15÷3

x=5

8z-20=z+15

8z-z=15+20

7z=35

z=35÷7

z=5

plzz mark me as brainliest

Answer:

3x-2=x+10

x=6

x+4=19-2x

x=5

8z-20=z+15

z=5

Step-by-step explanation:

3x-2=x+10

+2 on both sides

3x-2(+2)=x+10(+2)  =>  3x=x+12

subtract x on both sides

3x(-x)=x(-x)+12   =>  2x=12

divide 2 on both sides

2x/2=12/2

= x=6

x+4=19-2x

subtract 4 on both sides

x+4(-4)=19(-4)-2x    =>    x=15-2x

add 2x on both sides    

x(+2x)=15-2x(+2x)     =>    3x=15

divide 3 on both sides

3x/3=15/3

= x=5

8z-20=z+15

subtract z on both sides

8z(-z)-20=z(-z)+15    =>  7z-20=15

add 20 on both sides

7z-20(+20)=15(+20)

7z=35

divide 7 on both sides

7z/7=35/7

= z=5

Answer:

Step-by-step explanation:

x = -y + 10

Substitute into the second equation

-y + 10 = y + 4

-2y = -6

y = 3

Plug into first or second equation.

x = -3 + 10 = 7

x = 3 + 4 = 7

So the ordered pair is (7,3)

Answer: the 100th term of the sequence =-273 (1)

Step-by-step explanation:

Since the first term = 222

and d  (common difference )=-5 Then we are talking about an arithmetic progression

The nth term of an Arithmetic progression is given as

Tn=a + (n - 1)d

Therefore given that n =100

Tn=a + (n - 1)d = 222 +(100-1)-5

222+ (99)-5

222-495=-273

Answer:

54 degrees

Step-by-step explanation:

Every side of a regular pentagon is same.

So we have an  isosceles triangle. The  correspond angle of y, must equal to y (degree) too.

Also, every inner angle of a regular pentagon is 360/5=72. So we can calculate angle y, by the equation y+y+72=180.

y=54

Answer:

The answer is "(6,3)".

Step-by-step explanation:

In this question, the point is missing if the given point is (-6,-3) so, its solution can be defined as follows:

Throughout this question whenever we reverse the axis to the mirror at the point. The reflection of (-6,-3) is (6,3), which also is the correct value because it changes the coordinates, that's why (6,3) is the correct point.

62=f

If snowy tree crickets chirp at 100 chirps per minute, the temperature outside is 62 degrees fahrenheit.

Answer:

Step-by-step explanation:

First, find yourself a map. Then, using two points, find both the distance on the map and the true distance. Next, you divide the true distance by the measured map distance, and find your scale. Last, you need to place that ratio onto your map.

Answer:

y/2 = 4.5

Step-by-step explanation:

1/4x + 2y = 11/4

distribute by 4 to eliminate fractions

  x + 8y = 11

+ -x - 6y = 7

        2y = 18

          y = 9

half of 9 = 4 1/2

Hope that helps :)

Answer:

-26 is your answer

Step-by-step explanation: 2³ first which = 8 then solve in the parenthesis and all inside parenthesis = -19 so now you have -19+9-4². Now, solve 4² which = 16 so now you have -19+9-16 then solve that and it should give you -26.

Hope this helped you!!!!
