Answer:
12.72 m
Step-by-step explanation:
You're going to use the left side from the middle of AD up to point A. You see that's the same as a radius, so its length is 4.5. Then you can use the Pythagorean theorem to find the hypotenuse, the blue line from X to A.
(4.5)^2+(4.5)^2=x^2
40.5=x^2
x=6.36
and AC is two of the line you just figured out so 6.36x2=12.72m
Juanita borrowed $600 to purchase a new computer. She was charged 7% interest for two years. She used the simple interest formula to find the interest.
I = 600(7)(2)
What error did Juanita make and how will her error affect the interest she calculates? Explain.
please help
Answer:
The error she made was multiplyng by 7. This would affect her calculations as 7 in percentage form is represented as 700%. The 700% interest would basically mean she owes 7 times the amount she borrowed. The correct number would be 0.07 because 0.07 represents 7% which is the interest. Another error that was made was multiplying 2 to the entire equation. The only thing that needs to be doubled is the interest as every year the interest takes 7%. The correct way would be to put 0.07*2 in paranthesis. The correct equation is
I = 600(0.07*2)
Lines A and B are parallel

A car renting agency charges a fixed rate of $8 per day plus 8 cents per mile. If a family paid the agency $260 for the use of a car on a 2,450 mile trip, how many days was the car use
Answer: 8 days your welcome (:
Answer:
8 days
1day = $8.08
$8.08 * 8 = $64.64 so this is wrong.
$260/$8.08= about 31 days.
Stephanie can run 5 miles in 45 minutes. How long will it take her to run 10 miles?
Answer:
89
Step-by-step explanation:
so u have 5 miles in 45 mins so u do 45 x 2 then u get 89 minutes
Answer:
Stephanie can run 5 miles in
= 45 minutes
She can run 1 mile in
= 45/5
= 9 minutes
So, she can run 10 miles in
= 10×9
= 90 minutes or 1 hr 30 minutes
Irene is N years old. If Tom is twice as old, which of the following algebraic statements shows his age now?
A. 2n
B. 2n + x
C. 2 - n
D. n - 2
Explanation:
The n is a placeholder for a number. Writing 2n means we multiply by 2.
For example, if Irene is n = 20 years old, then Tom is 2n = 2*20 = 40 years old.
There are 24 red cars to every 96 blue cars. How many blue cars are there if there are 96 red cars?
Dividing the ratio of red and blue cars:
96 /24 = 4
There are 4 times as many blue cars as red cars.
Multiply the number of red cars by the scale factor:
96 red x 4 = 384 blue cars
Answer:
384 blue cars
Step-by-step explanation:
Here's how I do all of this in my head:
Divide 96 by 24:
96 ÷ 24 = 4
Now that we know that the number we need is 4, all we have to do is multiply both factors by 4.
96 × 4 = 384
24 × 4 = 96 (which is the number we're looking for)
So now that we have 96 red cars, we can see that there's 384 blue cars, which will be your answer.

Matt bought a 12-pack of water for $10.32. What was the unit rate?
We want to find the unit rate of the bottles of water given that we know that the cost of 12 bottles is $10.32, we will find that the unit rate is:
r = 1.16 (bottles/$)
The unit rate is defined as the rate of change per unit, in this particular case, the unit rate would be the cost of every single bottle of water.
Here, we do know that for $10.32, you get 12 bottles.
The unit rate is just given by the quotient between these two values:
(12 bottles)/($10.32) = 1.16 (bottles/$)
Meaning that the cost of every single bottle is $1.16

6/23 divided by 1/5 plz help
Answer:
30 / 23
Step-by-step explanation:
to divide two fractions, multiply by the reciprocal.
The reciprocal of 1/5 is 5/1. We will rewrite the equation as:
[tex]\frac{6}{23}[/tex] times [tex]\frac{5}{1}[/tex]
6 x 5 = 30
23 x 1 = 23
the answer is 30 / 23
The Quotient is 30/23.
What is Division?One of the four fundamental mathematical operations, along with addition, subtraction, and multiplication, is division. Division is the process of dividing a larger group into smaller groups so that each group contains an equal number of things.
Given:
6/23 divided by 1/5
As, division is not possible in fraction so we will perform the multiplication
= 6/23 ÷ 1/5
= 6/23 x 5
= 30/ 23

6. (a) Find a recurrence relation for the number of n-digit binary sequences with no pair of consecutive 1s. (b) Repeat for n-digit ternary sequences
(a) There are 2 sequences of length 1 that fit the bill: 0 and 1. So if [tex]b_n[/tex] is the number of permissible sequences, then [tex]b_1=2[/tex].
To the sequence 0, we can attach either 0 or 1 at the end, while the sequence 1 must be followed by 0. Then the permissible sequences of length 2 are 00, 01, and 10, so [tex]b_2=3[/tex].
Now consider a sequence of length n + 1, of which there are [tex]b_{n+1}[/tex].
• If the last digit is 0, then we got this sequence by simply joining 0 to one of [tex]b_n[/tex] sequences. In other words, there are [tex]b_n[/tex] permissible sequences of length n + 1 that end in 0.
• If the last digit is 1, then the previous digit must have been 0. Put another way, we join 01 to a permissible sequence of length n - 1 (there are [tex]b_{n-1}[/tex] of them). So there are [tex]b_{n-1}[/tex] permissible sequences of length n + 1 that end in 1.
These cases are mutually exclusive, so the number of (n + 1)-length permissible sequences is given by
[tex]\begin{cases}b_1 = 2 \\ b_2 = 3 \\ b_{n+1} = b_n + b_{n-2} & \text{for }n\ge2\end{cases}[/tex]
(b) The reasoning for a permissible ternary sequence is similar. Let [tex]t_n[/tex] be the number of sequences of length n not containing 11.
We first note that [tex]t_1 = 3[/tex], since we can have 0, 1, or 2; and [tex]t_2 = 8[/tex], since we can have 00, 01, 02, 10, 12, 20, 21, or 22.
Consider a sequence of length n + 1 ([tex]t_{n+1}[/tex] of these).
• If the last digit is 0, then we joined 0 to a permissible sequence of length n. So there are [tex]t_n[/tex] permissible sequences of length n + 1 ending in 0.
• If the last digit is 1, then the last two digits must be either 01 or 21. Since there are 2 choices for the n-th digit, there are [tex]2t_{n-1}[/tex] permissible sequences of length n + 1 ending in 1.
• If the last digit is 2, then we essentially have the same situation as if the sequence ended in 0, so there are [tex]t_n[/tex] sequences of length n + 1 ending in 2.
Then the recurrence for ternary permissible sequences is
[tex]\begin{cases}t_1 = 3 \\ t_2 = 8 \\ t_{n+1} = 2t_n + 2t_{n-1} & \text{for }n\ge2\end{cases}[/tex]
