Jane says that multiply a decimal by 100 is the same as multiplying the decimal by three factors of 10. Is Jane correct? Explain your answer.

Answers

Answer 1
Jane is incorrect, this is because 3 factors of ten equals 1000(10*10*10=1000) and 100 is not equal to 1000 meaning you are not multiplying by the same number.
Answer 2

Answer:

Jane is incorrect.

Step-by-step explanation:

We have been given a statement. We are asked to determine whether the given statement is true or not.

Jane says that multiply a decimal by 100 is the same as multiplying the decimal by three factors of 10.

[tex]\text{3 factor of 10}=10^3[/tex]    

[tex]\text{3 factor of 10}=10\times 10\times 10[/tex]

[tex]\text{3 factor of 10}=1000[/tex]

When we multiply a decimal by 100, it will move the decimal to two digits to right and multiplying a number by 1000 will the decimal to three digits to right.

Therefore, Jane is incorrect.

Any square root of a non-perfect-square number belongs to the set of irrational numbers; numbers which cannot be represented as ratios. Any number with a decimal component that either terminates (cuts off) or repeats is a member of the rational numbers, as they can be represented by ratios (1/3 for 0.3333... and 743/100 7.43). Any negative number without a decimal component is a member of both the rational numbers (-12 can be written in rational form as -12/1, -24/2, or any multiple -12n/n) and of the integers. Lastly, every positive integer is a member of the rationals, the integers, and the natural numbers (sometimes referred to as "counting numbers"; 1, 2, 3, etc.).

Lastly, I've attached a visual of how all of these number systems relate to one another within the context of the real number system:

What is the value of k in the function ƒ(x) = 112 - kx if ƒ(-3) = 121?
k =

Answers

Plug -3 into the function to get 112+3k=f(-3)=121.
So now can calculate k: 112+3k=121, 3k=9, k=3.
ok to solve for k, take the function f(x) = 112 - kx plug in the x value, so that would be f(-3) now we know that f(-3) = 121 so how to solve for k is quite easy. In replace f(-3) with 121 and x with -3
so 121 = 112 - k(-3) 
solve for k
subtract 112 from both sides
so that would give you 9 = -k(-3)
use the distributive property on -k(-3)
so that would be 3k = 9
divide both sides by 3
which gives you the answer k=3

Explain how you can find the numbers of ninths in 2 5/9

Answers

So first you have 2 5/9 and you divide it by nine which is 2 5/9 divided by 1/9
You convert 2 5/9 to a mixed number which is 23/9 and you can just use the 23 because that is the number of ninths.

Answer:

23 is the required answer.

Step-by-step explanation:

We are given a fraction of the form [tex]2\frac{5}{9}[/tex].

It is a mixed fraction.

We convert it into improper fraction.

The improper fraction is of the form [tex]\frac{(9\times2)+5}{9} = \frac{23}{9}[/tex].

This fraction can also be written as 23 multiplied [tex]\frac{1}{9}[/tex] times.

It is clear that the above fraction have 23 parts of ninth.

 

The sum of 5 consecutive integers is 505

Answers

Final answer:

To find the sum of 5 consecutive integers, use the formula (n + n+1 + n+2 + n+3 + n+4), where n is the first integer. The consecutive integers are 99, 100, 101, 102, and 103.

Explanation:

To find the sum of 5 consecutive integers, we can use the formula (n + n+1 + n+2 + n+3 + n+4), where n is the first integer. In this case, the sum is 505, so we have the equation: n + (n+1) + (n+2) + (n+3) + (n+4) = 505. Simplifying this, we get: 5n + 10 = 505. Subtracting 10 from both sides gives 5n = 495. Dividing both sides by 5, we find that n = 99.

Therefore, the 5 consecutive integers are 99, 100, 101, 102, and 103.

What is the equation of the line shown in the graph? Write the equation in standard form?

Answers

The line is completely horizontal. Every point on this line has a y coordinate of -3. The x value is allowed to be anything you want. In this case x = -2 and x = 3 is shown for the two points.

Since y is fixed to always being -3, this means y = -3 is the equation. If you want it to fit standard form then you can write it as 0x+1y = -3

Notice how 0x+1y = -3 matches up with Ax+By = C where
A = 0
B = 1
C = -3

Simplifying 0x+1y = -3 leads back to y = -3

In Zoe's class, 4/5 of the students have pets. Of the students who have pets, 1/8 have rodents. What fraction of the students in Zoe's class have pets that are rodents? What fraction of the students in Zoe's class have pets that are not rodents?

Answers

Final answer:

In Zoe's class, 1/10 of the students have pets that are rodents, while 7/10 have pets that are not rodents.

Explanation:

To calculate the fraction of students in Zoe's class who have pets that are rodents, you multiply the fraction of students who have pets by the fraction of those pet owners who have rodents:

4/5 × 1/8 = 4/40 or simplified, 1/10.

This means 1/10 of Zoe's class have rodents as pets.

Now, to find out the fraction of students with pets that are not rodents, subtract the fraction of students with rodents from the total fraction of students with pets:

4/5 - 1/10 = 32/40 - 4/40 = 28/40, which simplifies to 7/10.

So, 7/10 of Zoe's class have pets that are not rodents.

The possible values for the product [tex]\( a \cdot b \)[/tex] are between -14 and 14, inclusive.

Here's the step-by-step calculation:

1. To find the minimum possible value, we multiply the smallest values of ( a ) and ( b ):

[tex]\( a = -5 \) and \( b = -7 \)[/tex]

[tex]\( a \cdot b = (-5) \cdot (-7) = 35 \)[/tex]

2. To find the maximum possible value, we multiply the largest values of ( a ) and ( b ):

[tex]\( a = 2 \) and \( b = 1 \)[/tex]

 [tex]\( a \cdot b = 2 \cdot 1 = 2 \)[/tex]

So, the possible values for the product[tex]\( a \cdot b \)[/tex]  are between -14 and 14.

The range of values for( a ) is from -5 to 2, and for ( b ) is from -7 to 1. To find the extreme values of the product [tex]\( a \cdot b \),[/tex]  we multiply the smallest and largest values of ( a ) and ( b ).

For the minimum value, we take ( a = -5 ) and ( b = -7 ), which gives us [tex]( a \cdot b = 35 \).[/tex]

For the maximum value, we take ( a = 2 ) and ( b = 1 ), which gives us [tex]\( a \cdot b = 2 \).[/tex]

Therefore, the product[tex]\( a \cdot b \)[/tex] ranges from -14 to 14, inclusively.

Francois baked just enough cookies to fill all the orders at his bakery. While the cookies were cooling, a kitchen assistant knocked over a cooling rack and spilled %12, percent of the cookies onto the floor. Francois had to bake 36 more cookies to replace them. How many cookies were ordered in total?

Answers

300 cookies were ordered to start. 

We can tell this because we know 12% is equal to 36. Because this is true, we can set up a proportion to solve. All proportions can be set up with the small number on top and the total on the bottom. This will help you solve for the missing number, which is in this case the total number of cookies.  Let x be the total number of cookies.  

Percentage/total percentage = cookies/cookies total 
12/100 = 36/x

Now we can cross multiply to solve. 
(100)(36) = (12)(x) ----> multiply 
3600 = 12x ---> divide by 12
300 = x

A punter kicks a football upward with an initial velocity of 48 feet per second. After how many seconds does the ball hit the ground? use the formula h=rt-16t^2, where h represents height in feet and r represents the initial velocity (rate) in feet per second.

Answers

It would take 3 seconds for the ball to hit the ground

Given the initial velocity r = 48 feet per second feet per second, for the football to hit the ground, the height h will be 0.

Now, substitute the values, we have;

0 = 48t - 16t²

collect the like terms and rearrange to a quadratic equation, we get that;

16t² - 48t = 0

Now, we have to factor out the common term from the equation which is 16t, we have then that;

16t(t - 3) = 0

t- 3 = 0

collect the like terms, we get;

t = 3 seconds
