Answer:

b

Step-by-step explanation:

After a bone, wood fragment, or shell is buried in sediment, it may be exposed to mineral-rich water that moves through the sediment. This water will deposit minerals into empty spaces, producing a fossil. Fossil dinosaur bones, petrified wood, and many marine fossils were formed by permineralization.

Answer: fossils can be formed only when a living thing is buried soon after it dies. If it is not buried soon enough, it decays. For this reason, most fossils are found in sedimentary rocks that were once under water.

Answer:

(4,3)

Step-by-step explanation:

2y = x + 2

x - 3y = -5

Rearrange the second equation to equal y.

x - 3y = -5

x + 5 = 3y

(x+5)/3 = y

Substitute into the first equation.

2y = x +2

2[(x+5)/3] = x + 2

(2x + 10)/3 = x + 2

2x + 10 = 3(x + 2)

2x + 10 = 3x + 6

10 - 6 = 3x - 2x

4 = x

Therefore, the correct ordered pair is (4,3) since x is equal to 4.

Step-by-step explanation:

Step-by-step explanation: x = 73°

Draw PQ through E and parallel to AB, CD

Have x = ∠QED + ∠QEB

because PQ // CD => ∠QED = 50°

AB // PQ => ∠QEB + 157° = 180°

=> ∠QEB = 180 - 157 = 23°

=> x = 23° + 50° = 73°

( PQ   is in the same direction as AB and CD )

angle efd = 130

180-50=130

angle ahe =23

180-157= 23

draw a imaginary line from h to f

this will create a triangle

now angle hfc = 90

90-50=40

now angle hfe =

90 - 23 = 67

therefore ,

x =

67+40+x=180

107 + x = 180

x = 180-107

x=73

Answer:

F(-2) = 12

Step-by-step explanation:

F(-2) = (-2)²- 2(-2) + 4

= 4 - (-4) + 4

= 4 + 4 + 4

= 12

The required value of function F(x) = x² − 2x + 4 at F( -2 ) is 12.

A quadratic function is given F(x) = x² − 2x + 4, value of the function is to be determined at x = -2.

What is a polynomial function?

A polynomial function is a function that applies only integer dominions or only positive integer powers of a value in an equation such as the quadratic equation, cubic equation, etc. ax+b is a polynomial.

F(x) = x² − 2x + 4
Above given function is a quadratic function,
in order to find F(-2) , we have to put x = -2 in above given function.

F( -2 ) = ( -2 )² − 2( -2 ) + 4
F( -2 ) =  4 + 4 + 4
F( -2 ) =   16

Thus, the required value of function F(x) = x² − 2x + 4 at F( -2 ) is 12.

Answer:

x = 7

Step-by-step explanation:

all triangles add up to 180

(90 from the right angle)

90 + (4x) + (5x +27) = 180

117 + 9x = 180

-117          - 117

9x = 63

x = 63/9

x = 7

Answer:

x = 7

Step-by-step explanation:

All triangles add up to 180, and (90 from the right angle)

90 + (4x) + (5x +27) = 180

117 + 9x = 180

-117          - 117

9x = 63

x = 63/9

Therefore, x = 7

Answer: m<O = 11

Step-by-step explanation: you add angle N, O, and P to equal to 180° and when you solve that equation you get 11. Hopes this helps love u ❤️

The measure of angle O from the given triangle is 9°.

Given that, m∠N=(5x-8)°, m∠O=(x-5)° and m∠P=(6x+1)°.

We need to find the measure of angle O.

Angle sum property of triangle states that the sum of interior angles of a triangle is 180°.

Now, m∠N+m∠O+m∠P=180°

⇒ (5x-8)°+(x-5)°+(6x+1)°=180°

⇒ 5x+x+6x-8-5+1=180

⇒ 12x-12=180

⇒ 12x=192

⇒ x=192/12

⇒ x=16

So, m∠O = 16-5=9

Therefore, the measure of angle O from the given triangle is 9°.

Answer:

1:2

Step-by-step explanation:

You didn't really specify, but I'm going to assume you meant as simplified as possible. If you write it as a fraction, it will be ½ or as a decimal it will be 0.5.

Answer:

1:2

Step-by-step explanation:

Simplifying a ratio is like simplifying a fraction.

Simply put the number to the left as the numerator, and the number to the right as the denominator.

In this case, 3/6 = 1/2.

Hence, plug the numbers right back in and you get 1:2.

Step-by-step explanation:

Y = 5/2x on edge

The steepest graph is given by y= 5/2x.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

First, y= -2x

Here the slope is -2.

Second, y = -1/2 x

Here the slope is -1/2.

Third, y= 3/2x

Here the slope is 3/2 or 1.5

Fourth, y= 5/2x

Here the slope is 5/2 or 2.5

As, we know A steeper slope in a graph means that the rate of change is faster.

Then, y= 5/2x have steeper slopes.
