In your own words explain the place value relationship when the same two digits are next to each other in a multi digit number

1 answer:

8 0

In a place value relationships. The relationship between 2 the same digit place next to each other is the value of the number to left is 10 times bigger than to the value to the left and from the decimal point to the right is 10 times smaller of value than the digit in their right.

Let say for example:
1111
1 thousands, 1 hundreds, 1 tens, and 1 ones.
Let’s start from 1 = 1 x 10 = 10
That would be 10 X 10 = 100
then 100 X 10 = 1000

Notice that their value increase base on its place value if we multiply the given number by 10.

Another one is

912.98 in where 9 is hundreds, 1 is tens, 2 is ones and after the decimal points, in where 9 is tenths and 8 is hundredths.

Notice each place value next to each other. Each value is ten times in difference.

A dog walker charges a flat rate of $6 per walk plus an hourly rate of $30. How much does the dog walkercharge for a 45 minute w

leonid [27]

hello

from the question given, the dog walker charges a flat rate of $6 and an extra $30 per hour.

we can write out an equation in function notation

let the number of hours be represented by x

$f(x)=6+30x$

now we can proceed to solve the cost of the walk for 45 minutes

$\begin{gathered} 1hr=60\min s \\ \text{xhr}=45\min s \\ x=\frac{45}{60} \\ x=\frac{3}{4} \\ \text{therefore 45mins = 3/4 hours} \end{gathered}$

now we can input the value into the equation and know the cost for 45 minutes walk

$\begin{gathered} f(x)=6+30x \\ x=\frac{3}{4} \\ f(x)=6+30(\frac{3}{4}) \\ f(x)=6+22.5 \\ f(x)=28.5 \end{gathered}$

from the calculation above, the cost of 45 minutes walk will cost $28.5

The points J (-13,10) and K(-1,-6) are endpoints of a diameter of circle G. What is the equation of circle G?

In-s [12.5K]

The correct answer is D

The equation of a circle is (x-h)^2 + (y-k)^2 = r^2

to find (h,k), you find the middle of the circle, in this scenario you do so by finding the middle of the diameter, a line that goes through the center of the circle.

To find the X value of the midpoint, add both x values together and divide by 2 and repeat for y

-13 + -1 = -14
-14/2 =-7

10+ -6 = 4
4/2 = 2

therefore (h,k) = ( -7, 2 )

Next plug these values in the equation of a circle

(x-h)^2 + (y-k)^2 = r^2

becomes

(x- (-7)) ^2 + (y-(2)) ^2 = r^2

to find r, use the distance formula to find the length of the diameter, 20, and divide by 2

plug 10 in for r and you get 100

(x+7)^2 + (y-2)^2 = 100

sorry for the late response

Find the vertex I’d this parabola y=-2x^2-4x+4

mamaluj [8]

Answer:

(-1, 6)

Step-by-step explanation:

A graphing calculator shows the vertex to be (x, y) = (-1, 6).

You can also find it by putting the equation into vertex form.

y = -2(x^2 +2x) +4

y = -2(x^2 +2x +1) +4 +2(1) . . . . . add 1 inside parens; the opposite outside

y = -2(x +1)^2 +6

Compare to ...

y = a(x -h)^2 +k

and you see a=-2, h=-1, k=6

The vertex is (h, k) = (-1, 6).

Tristan is 22 years younger than Sydney. 8 years ago, Sydney's age was 2 times Tristan's age. How old is Tristan now?

Serjik [45]

Answer:

Sydney is 52 years old, and Tristan is 30.

Step-by-step explanation:

Represent Tristan's age by t and Sydney's by s.

Then s - 8 = 2(t - 8), and t = s - 22

Substituting s - 22 in the first equation, we get:

s - 8 = 2(s - 22 - 8), or

s - 8 = 2s - 60

Solving for s: -2s + s = -60 + 8, or -s = -52.

Sydney is 52 years old, and Tristan is 30.
