Answer:
The strands change color at the same time again after 90 seconds
Step-by-step explanation:
We are told:
Strand 1: changes between red and blue every 15 seconds.
Strand 2: changes between green and gold every 18 seconds.
To solve for this question, we use the LCM method.
Step 1
List multiples of each number until the first common multiple is found.
Multiples of 15:
15, 30, 45, 60, 75, 90, 105, 120
Multiples of 18:
18, 36, 54, 72, 90, 108, 126
Therefore,
LCM(15, 18) = 90
The first common multiple is 90, and this is the lowest common multiple.
Therefore, the strands will change color at the same time again after 90 seconds.
The scale of a map is 1.5cm : 75km. What is the actual distance between two

Is the side length √ 23+3 rational or irrational? Explain your reasoning.
100 points but If you answer something random I will report.
Answer:
Irrational
Step-by-step explanation:
[tex] \sqrt{23 + 3 } = \sqrt{26} [/tex]
An irrational number is a number that cannot be written as a fraction. Therefore √26 is an irrational number.
Irrational
Step-by-step explanation:
An irrational number is a number that cannot be written as a fraction. Which means that √23 is an irrational number.

What is the answer I feel like this is wrong?
Answer:
x = 6
Step-by-step explanation:
8 = (x/2) + 5
subtract 5 by both sides
3 = (x/2)
multiply by 2 on both sides
6 = x

Prove that the conjecture is false by providing a counter example.
Answer:
Any negative number would be a counterexample.
Step-by-step explanation:
Since negative numbers get smaller as you multiply them by a larger number, this would prove this conjecture false.

(7.15×105)–(5.964×105)
Answer:
124.53
Step-by-step explanation:
7.15×105=750.75
5.964×105=626.22
750.75-626.22= 124.53
lmk if this is right or not :)
Answer with step-by-step explanation:
(7.15 × 105) - (5.964 × 105) = 124.53
750.75 - 626.22 = 124.53

When a coordinate grid is superimposed on a map of lanesville the middle school is located at (15,13) and the librart is located at (27,9). If each unit represents 1 mile how many miles apart are the middle school in the liebrary round your answer to the nearest 10th
Answer:
4.5 miles
Step-by-step explanation:
Given
[tex]Middle\ School = (15,13)[/tex]
[tex]Library = (27,9)[/tex]
To solve this, we simply solve for the distance (D) between both points.
[tex]D = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]
Where:
[tex](x_1,y_1) = (15,13)[/tex]
[tex](x_2,y_2) = (27,9)[/tex]
[tex]D = \sqrt{(27 - 25)^2 + (9 - 13)^2}[/tex]
[tex]D = \sqrt{(2)^2 + (-4)^2}[/tex]
[tex]D = \sqrt{4 + 16}[/tex]
[tex]D = \sqrt{20}[/tex]
[tex]D=4.472135955[/tex]
[tex]D=4.5[/tex] --- approximated
Since each unit is 1 mile. The distance is 4.5 miles

Compare 2 4/5 ? 2.325
Answer:
>
Step-by-step explanation:
2.8>2.325
answer: > p l e a s e m a r k b r a i n l e s t .
this is because 2 4/5 = 2.800 and 2.800 is bigger than 2.325 because in the tenths place column (the column closest to the decimal without going over it), 8 is bigger than 3 so 2.800 is bigger than 2.325. So the answer is 2 4/5 > 2.325.
