Answer:
2000 meters
Step-by-step explanation:
The first step in this problem is to find 2/3 of 3 kilometers per hour.
2/3 * 3/1 = 6/3. This can be simplified to 2 kilometers per hour.
Now, find the rate of meters per minute. To do so, multiply 2 by 1000.
2 * 1000 = 2000
Therefore, at 2/3 of Lucia's rate, she walks 2000 meters per minute.
Answer:
The answer is 75 meters per minute.
Step-by-step explanation:
Ok I been seeing people say 2000 meter which is WRONG. 1 kilo= 1,000 meters
2/3 of an hour= 40 minutes
3,000 meters/40mins= 75 meters per minute

It costs Trevor $50 to have a security system installed in his house. He pays a monthly service fee plus tax of 6% of his monthly bill. After 6 months, Trevor had paid a total of $361.64 for his service fee, taxes, and his initial installation. Trevor’s monthly service fee, not including taxes, is ___.
Answer:
$49
Step-by-step explanation:
Cost of security system installation = $50
Let the monthly service cost be $x
In 6 month monthly service cost = 6*$x= $6xtax percentage = 6% of monthly service cost
hence if monthly service cost is $x
Then Tax value in terms of x is = 6% of $x = 6/100 * $x =$ 0.06x
In 6 month, Tax value in terms of x = 6 * $0.06x = $.36x_______________________________________________
Therefore total cost incurred by Trevor in 6 month including installation charges =
6 month monthly service cost + Tax value in 6 month + installation cost
Substituting value of 6 month monthly service cost , Tax value in 6 month , installation cost in above expression we have
Therefore total cost incurred by Trevor in 6 month including installation charges = $6x+ $0.36x+ $50 = $6.36x + $50
But it is given that After 6 months, Trevor had paid a total of $361.64 for his service fee, taxes, and his initial installation
Therefore total cost incurred by Trevor in 6 month including installation charges is also equal to $361.64
Hence,
$6.36x + $50 = $361.64
=> $6.36x = $361.64 - $50
=>$6.36x = $311.64
=> x = $311.64/6.36
=> x = 49.
Therefore , Trevor’s monthly service fee, not including taxes is $X which is equal to $49.

Answer:
18.5
Step-by-step explanation:
You are given the opposite side, and need to find the hypotenuse, leading you to use sine.
Set it up, like so:
[tex]sin67=\frac{17}{x} \\[/tex]
Multiply everything by x, to remove it from the denominator:
[tex]x(sin67=\frac{17}{x} )\\xsin67 = 17[/tex]
Divide both sides by sin67:
[tex]x = \frac{17}{sin67} \\x = 18.46[/tex]

Insert parentheses to make the statement true. 12 + 6 × 11 − 7 = 72 A. 12 + ( 6 × 11 ) − 7 = 72 B. 12 + 6 × ( 11 − 7 ) = 72 C. ( 12 + 6 ) × 11 − 7 = 72 D. ( 12 + 6 ) × ( 11 − 7 ) = 72
Answer:
D hope this help :)
Step-by-step explanation:(☞ﾟヮﾟ)☞☜(ﾟヮﾟ☜)
(12 + 6) × (11 − 7) = 72, is equal to 72 is a True statement.
The correct option is D.
To make the statement true by inserting parentheses, we need to follow the correct order of operations (also known as the PEMDAS or BODMAS rule).
According to this rule, multiplication and division should be performed before addition and subtraction.
Let's examine the options:
A. 12 + (6 × 11) − 7 = 72
B. 12 + 6 × (11 − 7) = 72
C. (12 + 6) × 11 − 7 = 72
D. (12 + 6) × (11 − 7) = 72
To determine the correct option, let's evaluate each expression:
A. 12 + (6 × 11) − 7 = 12 + 66 − 7 = 71 (not equal to 72)
B. 12 + 6 × (11 − 7) = 12 + 6 × 4 = 12 + 24 = 36 (not equal to 72)
C. (12 + 6) × 11 − 7 = 18 × 11 − 7 = 198 − 7 = 191 (not equal to 72)
D. (12 + 6) × (11 − 7) = 18 × 4 = 72
Thus, (12 + 6) × (11 − 7) = 72, is equal to 72 is a True statement.

Reasoning in a laboratory, the probability a bacterial colony thrives is 70%. The numbers 0 to 6 represent the outcome that a colony thrives. The numbers 7 to 9 represent the outcomes that a colony does not thrive. The list of random numbers simulates the out comes of 4 colonies . Based On the simulation in 6 trails . what is the probability that exactly half of the colonies will thrive.
4285 6903 3829 7871 2868 5137
Answer:
The probability that exactly half of the colonies will thrive = (1/3) = 0.3333
Step-by-step explanation:
The list of random numbers simulates the out comes of 4 colonies.
Based On the simulation in 6 trails, what is the probability that exactly half of the colonies will thrive?
The probability of an event is given mathematically as the number of elements in the event divided the total number of elements in the sample space.
Noting that the numbers 0 to 6 indicate that a colony thrives and the number 7 to 9 represent that a colony doesn't thrive.
The 6 trials are given as
4285; 3 colonies thrive, 1 doesn't.
6903; 3 colonies thrive, 1 doesn't.
3829; 2 colonies thrive, 2 don't.
7871; 1 colony thrives, 3 don't.
2868; 2 colonies thrive, 2 don't.
5137; 3 colonies thrive, 1 doesn't.
The number of trials where exactly 2 colonies thrive = 2
The total number of trials = 6
The probability that exactly half of the colonies will thrive = (2/6) = (1/3) = 0.3333

Answer:
it's A, one yard and 20 inches
Step-by-step explanation:
If you convert them all to inches, a yard and a 20 inches are equal to 56 inches, so you can rule out the 40 inches answer. a yard and a foot are equal to 48 inches, so we can rule out that also. 3 feet is equal to 36 inches, because we know that a foot is equal to 12 inches. so you are left with A. 1 yard and 20 inches.
