Answer:

The correct answer is Option 3: 12y

Step-by-step explanation:

A polynomial term is usually made of a variable and a co-efficient.

Like terms are those terms that have the same variables i.e. x and 44x are like terms.

Given expression is:

[tex]6y-2y+8y[/tex]

All the terms have only y which means that all three terms are alike.

The coefficients of like terms are added or subtracted according to their sign.

[tex]6y-2y+8y[/tex] = 12y

Hence,

The correct answer is Option 3: 12y

Answer: 10 pieces of two by four woods.

Step-by-step explanation:

The number of woods that would be needed depends on the type of design chosen. A more complex design would require more wood to achieve it so it can satisfy the law of buoyancy and float on the water.

10 pieces of two by four would would be enough to build a raft that would float on water.

Answer:

Teachers already introduce the general concept of revolutions (turns) when they say things like "a full circle is 360°", but they can make the concept more numerically precise by saying "a full turn is 360°, a half turn is 180°, a quarter turn is 90°, and an eighth turn is 45°" or writing "1 rev = 360°, 1/2 rev = 180°, ...

Answer:

An angle that turns through 1 360 of a circle what is the measure in degrees of the angle

Step-by-step explanation:

Angles are typically measured in degrees or radians. Angle measure is based on a circle where a full turn around the circle is 360 degrees. Similarly, a half turn is 180 degrees, a fourth [quarter] turn is 90 degrees, and so on.

Answer:

z=-3

Step-by-step explanation:

Answer:

z=3

Step-by-step explanation:

42=−7(z−3)

Simplify both sides of the equation.

42=−7(z−3)

42=(−7)(z)+(−7)(−3)(Distribute)

42=−7z+21

Flip the equation.

−7z+21=42

Subtract 21 from both sides.

−7z+21−21=42−21

−7z=21

Divide both sides by -7.

-7z/-7=21/7

z=3

Answer:

96 tickets

Step-by-step explanation:

This question is incomplete, the complete question is;

Lets consider a hypothetical airline, Mudlark Airlines. On one of its flight, previous records show that about 15% of people who had tickets for the flight did not take the flight. There are 120 seats on the plane.

Suppose that Mudlark decides to sell 140 tickets for this flight. Assuming that all 140 tickets are sold and that the outcome for each ticketholder is independent, how many ticketholders should the airline expect to show up

Answer: the airline should expect 119 ticketholders to show up

Step-by-step explanation:

Given that;

the plane contains 120 seats

Their records shows that 15% (0.15) percent of people who previously buy their flight tickets don't show up.

they sold 140 tickets,

Number of ticketholder expected to show up  = ?

Probability of showing up for flight will be;

⇒ 1 - 0.15 = 0.85

Now Expected number of ticketholders to shup will be;

⇒ 140 × 0.85

= 119

Therefore the airline should expect 119 ticketholders to show up

Answer:  the value of the diversity index D for the population is 0.42

Step-by-step explanation:

Given that; population of the two species are

p1 = 30% = 0.3 (snapping turtle)

p2 = 70% = 0.7 ( box turtle)

so if two (2) organisms are picked, then they can be different from each other ( i.e Event E) under following two scenarios

E1 → First organism selected from p1 and second organism selected from p2

E2 → First organism selected from p2 and second organism selected from p1

which means we are observing the different orders in which the organisms can be picked.

So the probability of event E = the sum of probabilities of events E1 and E2.

which is;

D = P(E) = P(E1) + P(E2)

= P1×P2 + P2×P1

= 2P1P2

so we substitute

D = 2 × 0.3 × 0.7

D = 0.42

Therefore the value of the diversity index D for the population is 0.42

Answer:

1. To dilate something in the coordinate plane, multiply each coordinate by the scale factor. This is called mapping. For any dilation the mapping will be \begin{align*}(x, y) \rightarrow (kx, ky)\end{align*}. In this Concept, the center of dilation will always be the origin, unless otherwise stated.

2. When using State Plane coordinates the scale factors, also known as the K factors, are ratios that can be used as multipliers to convert ellipsoidal lengths, also known as geodetic distances, to lengths on the map projection surface, also known as grid distances, and vice versa.

3.Similar figures have the same shape (but not necessarily the same size) and the following properties: Corresponding sides are proportional. That is, the ratios of the corresponding sides are equal. Corresponding angles are equal.

Answer:

Step-by-step explanation:

Answer: (4x2 + 4x - 5) • (x - 1)

Step-by-step explanation: The Rational Root Theorem states that if a polynomial zeroes for a rational number  P/Q   then  P  is a factor of the Trailing Constant and  Q  is a factor of the Leading Coefficient

In this case, the Leading Coefficient is  4  and the Trailing Constant is  5.

The factor(s) are:

of the Leading Coefficient :  1,2 ,4

of the Trailing Constant :  1 ,5

The Factor Theorem states that if P/Q is root of a polynomial then this polynomial can be divided by q*x-p Note that q and p originate from P/Q reduced to its lowest terms

In our case this means that

  4x3-9x+5

can be divided with  x-1

2.2    Polynomial Long Division

Dividing :  4x3-9x+5

                             ("Dividend")

By         :    x-1    ("Divisor")

dividend     4x3      -  9x  +  5

- divisor  * 4x2     4x3  -  4x2        

remainder         4x2  -  9x  +  5

- divisor  * 4x1         4x2  -  4x    

remainder          -  5x  +  5

- divisor  * -5x0          -  5x  +  5

remainder                0

Quotient :  4x2+4x-5  Remainder:  0

2.3     Factoring  4x2+4x-5

The first term is,  4x2  its coefficient is  4 .

The middle term is,  +4x  its coefficient is  4 .

The last term, "the constant", is  -5

Step-1 : Multiply the coefficient of the first term by the constant   4 • -5 = -20

Step-2 : Find two factors of  -20  whose sum equals the coefficient of the middle term, which is   4 .

     -20    +    1    =    -19

     -10    +    2    =    -8

     -5    +    4    =    -1

     -4    +    5    =    1

     -2    +    10    =    8

     -1    +    20    =    19

Observation : No two such factors can be found !!

Conclusion : Trinomial can not be factored

Answer:

The last option

Step-by-step explanation:

a is the hypotenuse, x is the adjacent, h is the opposite.

a^2 = h^2 + x^2

Subtract x^2 from both sides

h^2 = a^2 - x^2

Answer:

Step-by-step explanation:

Answer:

a) f(0) = -9

b) f(2) = -5

c) f(-3) = -15

d) f(1/2)=-8

Step-by-step explanation:

We are given the function [tex]f(x)=2x-9[/tex] and we need to find the following:

a) f(0)

For finding f(0) put x =0 in the given function

[tex]f(x)=2x-9\\Put\:x=0\\f(0)=2(0)-9\\f(0)=-9[/tex]

So, we get f(0)=-9

b) f(2)

For finding f(2) put x =2 in the given function

[tex]f(x)=2x-9\\Put\:x=2\\f(2)=2(2)-9\\f(2)=4-9\\f(2)=-5[/tex]

So, we get f(2)=-5

c) f(-3)

For finding f(-3) put x =-3 in the given function

[tex]f(x)=2x-9\\Put\:x=-3\\f(-3)=2(-3)-9\\f(-3)=-6-9\\f(-3)=-15[/tex]

So, we get f(-3)=-15

d) f(1/2)

For finding f(1/2) put x =1/2 in the given function

[tex]f(x)=2x-9\\Put\:x=\frac{1}{2}\\f(\frac{1}{2})=2(\frac{1}{2})-9\\f(\frac{1}{2})=1-9\\f(\frac{1}{2})=-8[/tex]

So, we get f(1/2)=-8

Answer:

He makes 4 batches of cookies with all of the chocolate chips so he will use 4 times the amount of batter in 1 batch so you would do 5 1/2 times 4 which eqauls 22 so he will use 22 cups of cookie dough.

So your answer is D. 22 cups

Step-by-step explanation:

The number of cups of cookie dough does the baker use is 22 cups.

Given that,

Based on the above information, the calculation is as follows:

[tex]= 5\frac{1}{2} \times 4\\\\= \frac{11}{2}\times 4[/tex]

= 22 cups  

Therefore we can conclude that the number of cups of cookie dough does the baker use is 22 cups.

Answer:

Step-by-step explanation:

This can happen because of the timestamp on the toll card. When you pass through the initial entrance point the timestamp marks the exact moment you passed. When you pass through the exit toll point the individual subtracts the current time from the time you entered the initial toll entrance. From this, he can easily determine the average speed that you were driving at. If the average speed is higher than the speed limit, it means that at some point between the two toll booths you were speeding and therefore they can give you a speeding ticket.
