What is the greatest common factor of 20y^9 + 5y^6 ?

A. 5y^9
B. 20y^3
C. 5y^6
D. 10y^9

Answers

greatest common factor of 20y^9 + 5y^6 = 5y^6

answer
C. 5y^6 
Final answer:

The greatest common factor of 20y^9 + 5y^6 is 5y^6.

Explanation:

To find the greatest common factor (GCF) of 20y^9 + 5y^6, we need to determine the highest power of each variable that divides each term evenly. In this case, the highest power of y that can be divided evenly is y^6. The GCF of the two terms is therefore 5y^6.

The diameter of the attic is 18ft and its height is 18ft. What's is the volume of the space in the attic

Answers

I attached an image with the complete question.

Answer:
volume of attic = 1526.04 ft³

Explanation:
Volume of cone can be calculated using the following rule:
Volume = [tex] \frac{1}{3} [/tex] * area of base * height
Volume = [tex] \frac{1}{3} [/tex] * π * radius² * height
We are given that:
π = 3.14
radius = 18/2 = 9 ft
height = 18 ft

Substitute in the equation to get the volume as follows:
Volume = [tex] \frac{1}{3} [/tex] * 3.14 * (9)^2 * (18) = 1526.04 ft³

What is the probability of not rolling a 2?

Enter your answer as a fraction, in simplest form, in the box.

Answers

6 numbers rolling a 2 = 1/6
 so rolling something other than a 2 would be 5/6

Answer:  The probability of not rolling a 2 is [tex]\dfrac{5}{6}.[/tex]

Step-by-step explanation:  Given that a number cube has sides numbered 1 through 6. And the probability of rolling a 2 is [tex]\dfrac{1}{6}.[/tex]

We are to find the probability of not rolling a 2.

Let, 'A' denotes the event of rolling a 2.

So, we have

[tex]P(A)=\dfrac{1}{6}.[/tex]

The event of not rolling a 2 is given by the complement of event A.

The probability of the complement of event 'A' can be calculated as

[tex]P(A')=1-P(A)=1-\dfrac{1}{6}=\dfrac{5}{6}.[/tex]

Thus, the probability of not rolling a 2 is [tex]\dfrac{5}{6}.[/tex]

write 10 21/40 as a decmial

Answers

10 21/40 =
10. 525

The 10 stays 10. 
Divide 21 by 40 = 0.525

To write 10 21/40 as a decimal, we could use the equation 10 + (21 ÷ 40) to find the solution. So, 10 + (21 ÷ 40) (=) 10 + (.525) = 10.525. So, the decimal for 10 21/40 is 10.525.

A scientist is measuring the amount of radioactive material in an unknown substance. When he begins measuring, there are 56.8 grams of radioactive substance. Twelve days later, there are 55.45 grams. After 25 days, there are 54.03 grams. After 41 days, there are 52.32 grams. Assuming that the decay is exponential, find the equation that determines the number of grams remaining after x days and use the equation to determine the amount of radioactive material remaining after 500 days.

2.21 g

12.65 g

2.25 g

20.88 g

Answers

Universal law of radioactive decay states that:
[tex]N=N_0e^{-\lambda t}[/tex]
Where No is an initial number of atoms, N is a number of atoms after time t and lambda is the decay constant. We can use mas of an atom instead of a number of atoms because we know that every atom has the same mass.
[tex]M=M_0e^{-\lambda t}[/tex]
In order to calculate how many atoms are left after 500 days, we need to find decay constant.
We can do this by using the information given in the problem. We know that after 12 days we are left with 55.45 grams and we know the initial amount. With this information we can calculate decay constant:
[tex]M=M_0e^{-\lambda t}\\ 55.45=56.8e^{-12\lambda}\\ 0.976=e^{-12\lambda}\\ ln(0.976)=-12\lambda\\ -0.0243=-12\lambda\\ \lambda=\frac{0.0243}{12}\\ \lambda=0.002[/tex]
Now we simply plug in t=500 and calculate the answer:
[tex]M=M_0e^{-\lambda t}=56.8 e^{-0.002\cdot 500}=56.8e^{-1}=\frac{56.8}{e}=20.88g[/tex]
The final answer is D (20.88g).

When, reflection takes place,the two, Image, and Pre-Image are Congruent, that is neither the shape nor the Size changes only translation of the shape takes place on the coordinate plane.

Option C: → Reflection across y = x.

Answer:

C. reflection across y = x

Step-by-step explanation:

The given transfomation is

[tex]A(-1,3) \implies A'(3,-1)\\B(2,4) \implies B'(4,2)\\C(-5,6) \implies C'(6,-5)[/tex]

Notice that the rule of the given transformation is

[tex](x,y) \implies (y,x)[/tex]

That is, the coordinates were change of position, like an inverse.

According to transformation rules, this represents a reflection across the line [tex]y=x[/tex].

Therefore, the right answer is C.

Rewrite the following equation in slope-intercept form. 14x + 15y = 11 Write your answer using integers, proper fractions, and improper fractions in simplest form.

Answers

The given equation is transformed into slope-intercept form as y = -14/15 * x + 11/15, where the slope is -14/15, and the y-intercept is 11/15.

To rewrite the equation 14x + 15y = 11 in slope-intercept form (y = mx + b), where m is the slope and b is the y-intercept, we need to isolate y.

Starting with the given equation:

14x + 15y = 11.

Subtract 14x from both sides:

15y = -14x + 11.

Divide both sides by 15 to solve for y:

y = -14/15 * x + 11/15.

Now, the equation is in slope-intercept form. The slope (m) is -14/15, and the y-intercept (b) is 11/15.

In summary, the equation 14x + 15y = 11 is rewritten in slope-intercept form as y = -14/15 * x + 11/15.

How to determine the set that shows a positive nonlinear association between x and y?

The set is given as:

Set A

x 1 2 3 4 5 6 7 8 9

y 10 9 8 7 6 5 4 3 2

Set B

x 1 2 3 4 5 6 7 8 9

y 3 4 5 6 7 8 9 10 11

Set C

x 1 2 3 4 5 6 7 8 9

y 8 6 5 4 3.5 3 2.5 2 2

Set D

x 1 2 3 4 5 6 7 8 9

y 1 2.5 2.5 3 4 5 6 8 9

For the set to represent a non linear association, then the variables increases or decreases as the other variable changes but the direction must form a curved pattern.

Sets A, B and D are linear asociation because the output variables increases or decrease as the input variable increases

Hence, the set C shows a positive nonlinear association between x and y

a number multiplied by -8, subtracted from the sum of 14 and five times the number

Answers

(14 + 5z) - (-8z) OR (14 + 5z) + (8z)

z= the number

Let us suppose the number is x. Now we try to make an algebraic expression going step by step.

Step 1:

Five times the number means 5 multiplied by x.

So it becomes 5x.

Step 2:

Sum of 14 and five times the number means 5x+14.

Step 3:

Number multiplied by -8 means -8x.

Step 4:

Subtract the expression in step (3) from expression in step (2)

5x+14-(-8x)

Now we can simplify it further,

5x+14+8x

Combining like terms,

13x+14

Answer: The final expression becomes 13x+14.

Write an equation that you can use to solve for x. Enter your answer in the box. Two lines intersect at a point, forming two adjacent angles. One adjacent angle is labeled x degrees and the other adjacent angle is labeled 47 degrees.

Answers

The equation would be x+47=180.

The adjacent angles formed by these two adjacent angles are supplementary; that means that they sum to 180°.

We would solve this by subtracting both sides by 47:
x+47-47=180-47
x=133

Answer: The value of x is 133°.

Step-by-step explanation:

Since we have given that

Two lines intersect at a point forming two adjacent angles.

Measure of one adjacent angle is labeled as = x degrees

Measure of other adjacent angle is labeled as = 47 °

We need to find the value of x in degrees.

As shown in the figure:

Since they are adjacent angles.

So, we can write it as

[tex]x+47^\circ=180^\circ\\\\x=180^\circ-47^\circ\\\\x=133^\circ[/tex]

Hence, the value of x is 133°.

Answer:

landing on a shaded portion and landing on an even number ; landing on a shaded portion and landing on a number greater than 3 ; landing on an unshaded portion and landing on an odd number ; and landing on an unshaded portion and landing on a number less than 2.

Explanation:

Mutually exclusive events are events that cannot occur at the same time.  Our spinner has two grey sections, on 1 and 3; and two white sections, on 2 and 4.

This means that the spinner cannot land on a shaded (grey) portion and land on an even number at the same time, since the grey sections are numbered 2 and 4, both of which are even numbers.

The spinner also cannot land on a shaded (grey) portion and land on a number greater than 3 at the same time; this is because the only number greater than 3 on the spinner is 4, which is a white portion.

The spinner cannot land on an unshaded (white) portion and land on an odd number, since the white sections are labeled 2 and 4, which are both even.

The only number on the spinner less than 2 is 1, which is grey; this means the spinner cannot land on a number less than 2 and an unshaded (white) portion at the same time.
