i am horrible in math. help a girl out . 20 points for giving me answers

Answer:

I checked it and the person above me is correct. Give em brainlyest! Your welcome other person

Step-by-step explanation:

Answer:

A and B are 63°

Step-by-step explanation:

angles on a straight line add to 180

180-107 = 73

vertcally oppsite angles are equal

Answer:

73

Step-by-step explanation:

107 plus 107 = 214. 360-214=146. 146÷2=73

Answer:

why? also the answer is 1.6y+y-4/15y+7/6y=21/3

We move all terms to the left:

1.6y+y-4/15y+7/6y-(21/3)=0

Domain of the equation: 15y!=0

y!=0/15

y!=0

y∈R

Domain of the equation: 6y!=0

y!=0/6

y!=0

y∈R

We add all the numbers together, and all the variables

1.6y+y-4/15y+7/6y-7=0

We add all the numbers together, and all the variables

2.6y-4/15y+7/6y-7=0

We calculate fractions

2.6y+(-24y)/90y^2+105y/90y^2-7=0

We multiply all the terms by the denominator

(2.6y)*90y^2+(-24y)+105y-7*90y^2=0

We add all the numbers together, and all the variables

(+2.6y)*90y^2+(-24y)+105y-7*90y^2=0

We add all the numbers together, and all the variables

105y+(+2.6y)*90y^2+(-24y)-7*90y^2=0

Wy multiply elements

-630y^2+105y+(+2.6y)*90y^2+(-24y)=0

We get rid of parentheses

-630y^2+105y+(+2.6y)*90y^2-24y=0

We add all the numbers together, and all the variables

-630y^2+81y+(+2.6y)*90y^2=0

Answer: B

Step-by-step explanation:

Answer:

x = 11

y = 3

Step-by-step explanation:

4y+1=6y-5

-4y   -4y

+1   =2y-5

+5       +5

  6/2=2y/2

      3=y

2x-4=  18

  +4    +4

2x/2 = 22/2

      x=11

Answer:

  30 m²

Step-by-step explanation:

The figure can be thought of as a 6 m × 6 m square with a triangle cut off of the corner. That triangle has a base of 6-3 = 3 m, and a height of 6-2 = 4 m. Then the area of the figure is ...

  pen area = square area - triangle area

  pen area = (6 m)² - (1/2)(3 m)(4 m)

  pen area = 36 m² -6 m²

  pen area = 30 m²

__

The formula for the area of a square of side s is ...

  A = s²

The formula for the area of a triangle with base b and height h is ...

  A = (1/2)bh

It is useful to remember these formulas.

Answer:

Cos 2u = 7/25

Step-by-step explanation:

Here, we want to find the value of cos2u

Using formula, we can rewrite cos 2

Mathematically;

cos 2u = 2cos^2 U - 1

Thus, we have that

cos 2u = 2(4/5)^2 - 1

cos 2u = 2(16/25) - 1

cos 2u = 32/25 - 1

cos 2u = (32-25)/25 = 7/25

Answer:They are 600 feet apart from each other

Step-by-step explanation:

Answer:

600

Step-by-step explanation:

the 200 since its below the surface it would become negitive and 400 - -200 would turn into 400 + 200 and that would be 600 :)

Answer:

C

Step-by-step explanation:

30 x 4 = 120 justina collection is 30 and shamea's is 120, 30 + 120 = 50

Answer:

30

Step-by-step explanation:

There's a proper way to do this, but I forgot.

I ended up just plugging the numbers in to see if they worked;

120(4) + 120 is too much to be 150;

40(4) + 40 is 200, still too much to be 150;

30(4) + 30 is 150, exactly

So your answer is C, 30.

Hope this helps!

Answer:

[tex]A_2 = 7.5cm^2[/tex]

Step-by-step explanation:

The attachment completes the question

Given

[tex]Area = 15cm^2[/tex]

Required

Area of green triangle

[tex]The\ area\ of\ a\ parallelogram\[/tex] is calculated as

[tex]A_1 = b * h[/tex]

and

[tex]A_1 = 15cm^2[/tex]

Where:

[tex]b=base[/tex]

[tex]h = height[/tex]

Because the triangle shares exact base and height with the parallelogram, the area of a triangle is calculated as

[tex]A_2 = \frac{1}{2} * b * h[/tex]

Recall that:

[tex]A_1 = b * h[/tex]

So, we have:

[tex]A_2 = \frac{1}{2} *A_1[/tex]

Substitute [tex]15cm^2[/tex] for [tex]A_1[/tex]

[tex]A_2 = \frac{1}{2} * 15cm^2[/tex]

[tex]A_2 = \frac{ 15cm^2}{2}[/tex]

[tex]A_2 = 7.5cm^2[/tex]

The area of the triangle is 7.5cm^2
