Answer 1

Answer:

[tex]b_{2} = \frac{2A}{h} - b_{1}\\[/tex]

Step-by-step explanation:

[tex]A = \frac{1}{2} h(b_{1} +b_{2})\\2A = h(b_{1} +b_{2})\\\frac{2A}{h} = b_{1} +b_{2}\\\frac{2A}{h} - b_{1} = b_{2}\\[/tex]

in a population of grasshoppers, the ratio of grasshoppers with a white marking to those without a white marking is 2:3. An entomologist captures and photographs 290 grasshoppers. How many photographs are likely to show grasshoppers with a white marking?
A. 193
B. 58
C. 112
D. 116

Answers

Answer:

D. 116

Step-by-step explanation:

Let the grasshoppers with a white marking be 2x.

Let the grasshoppers without a white marking be 3x.

2x + 3x = 290

5x = 290

x = 290 / 5

x = 58

The grasshoppers with a white marking

= 2x

= 2 ( 58 )

= 116

Answer:

200 m^3

Step-by-step explanation:

1) find the side of the base

side = 40 : 4 = 10 m

2) find the base area

base area = side^2 = 10^2 = 100 m^2

3) find the Volume

V = (base area x height)/3 = (100 x 6)/3 = 200m^3

-2x - 9y = -3
--7x - 9y = -33

Answers

Answer:

x = 6 and y = -1

Step-by-step explanation:

hope this helps

Answer:

x= 6 and y= -1

Step-by-step explanation:

-2x - 9y = -3

-7x - 9y = -33

I'm going to be solving by elimination. However, you can solve using substitution as well.

So the first step is to eliminate one of the variables. In my opinion, what's easiest is eliminating the y variables. To eliminate you want to variables (that are the same) to equal 0 and cancel out. To do this, all I have to do is subtract. When I subtract I get 0 as shown below. I will also subtract the other variables and numbers in the equations because that's how elimination works.

-2x - 9y = -3

-7x - 9y = -33

5x = 30

-2 - (-7)=5 and -3 - (-33)= 30

There's no solution for the y variable because -9 - (-9)=0, which cancels out so it doesn't have to be written.

after that you get x=6 because you divide by 5 on both sides.

All that's left is to plug in 6 to one of the equations:

-2(6) - 9y= -3

-12 - 9y= -3

+12         +12

-9y= 9

Divide both sides by -9 to get y= -1

Consider the small left triangle. By Pythagorus:

y²=6²+x²

Question 2 options:

16

40

46

52

Answers

Answer:

A) 16

Step-by-step explanation:

1st sequence: 72-8x

2nd sequence: 58-6x

Set both sequences equal to each other and solve for x:

72-8x=58-6x

14-8x=-6x

14=2x

7=x

x=7

Plug x=7 back into the equation:

72-8(7)=58-6(7)

72-56=58-42

16=16

So the first number that appears in both sequences is 16.

Find the value of y. Geometry, plz only answer if you know how to do it ! thanks

Answers

Answer:

y = 96

Step-by-step explanation:

In order to find y we have to find the value of  x

angle "x" is an angle formed by a tangent line and a secant line.

Kindly look at the image.

As you can see an angle formed by a tangent and a secant is equal to half of its intercepted arc.

x's intercepted arc has a measure of 168

So...

X = [tex]\frac{168}{2}[/tex]

[tex]\frac{168}{2} =84[/tex]

So x = 84

Now to find y.

Angle "x" and angle "y" are formed on a straight line.

Angles formed on a straight line add up to equal 180°

That being said we can find a missing angle ( y ) by subtracting the given angle's measure ( angle x which has a measure of 84°) from 180

so y = 180 - 84

180 - 84 = 96

Hence y = 96

Step-by-step explanation:

math

Answer:

1. x = 42

2. y = 46

3. z = 0

Step-by-step explanation:

1. 45 + x = 87

         subtract 45 from both sides

  x = 42

2. y - 31 = 15

         add 31 to both sides

  y = 46

3. 5z = 0

         divide 5 from both sides

  z = 0/5

         since any fraction with a numerator of 0 is equal to 0, we get

  z = 0
