How common is LSD use among high school seniors?LSD use among secondary school understudies is a specific concern. In excess of 8% of secondary school seniors in the United States utilized the medication something like once in the course of their life, and almost 4% involved the medication in the previous year, as per the University of Michigan's Monitoring the Future Survey. In spite of the fact that by the 1980s LSD use had extraordinarily declined, it made a resurgence during the 1990s, basically among teens. An overview led by Monitoring the Future Study discovered that 13.6 percent of 1997's secondary school seniors had tried different things with LSD no less than once contrasted with just 7.2 percent in 1986.

Answer:25
Step-by-step explanation:
If sea level = 0, write an integer that represents 25 feet below sea level.
Answer: -25
Step-by-step explanation:
The required integer that shows that 25 feet below the sea level is -25.
Given that,
To determine the in integer that represents 25 feet below sea level.
A number line is defined as the number marked on the line calibrated into an equal number of units. For example -1, 0, 1, and so on.
Here,
The sea level is set to equal to 0,
Now height above the seal level comprises of positive sign, and the height below the sea level comprises of negative sign.
So, for 25 feet below sea level,
-25 is the required integer that represents the 25 feet below sea level.
Thus, the required integer that shows that 25 feet below sea level is -25.

Based on the given parameters, Eli’s speed is 5/60 miles per minute
What is Speed?The speed of an object is the rate of change of the distance moved by the object with respect to time
How to determine Eli's speed?The given parameters are
Distance = 5/6 miles
Time = 10 minutes
The speed is calculated as
Speed = Distance/Time
So, we have
Speed = 5/6 miles/10 minutes
Evaluate
Speed = 5/60 miles per minute

Step 2: Solve for x
Distribute 7: 2x - 5 = 3Isolate x term: 2x = 8Isolate x: x = 4Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 7(2(4) - 5) = 21Multiply: 7(8 - 5) = 21Subtract: 7(3) = 21Multiply: 21 = 21Here we see that 21 does indeed equal 21.

Answer:
x = 3 is the solution
Step-by-step explanation:
3x + 4 = 5x - 2
when x = 3
so plug 3 into the equation where x is
so the equation becomes:
3(3) + 4 = 5(3) - 2
Then do the multiplication on both sides
9 + 4 = 15 - 2
Then do the addition and subtracition on both sides
13 = 13
Answer:
3x +4= 5x-2
3(3) +4 = 5(3) -2 (plug in the x values)
9+4= 15-2 (do the multiplication on both sides)
13= 13 (do the addition/ subtraction. pretty much all you're doing, is making sure that with the given x-value, the equation is true. and it is :))

22) The length of tangents drawn from
an external point to a circle are equal to
4 cm and radius is 3 cm then the
distance of external point from the
centre is
O 2 cm
O 3 cm
O 4 cm
O 5 cm
Answer:
The length from the external point to the center of the circle is 5 cm
Step-by-step explanation:
Here, we want to calculate the distance from the center of the circle to the external point
Please check attachment for diagram
Now, from what we know, the tangent and the radius meets at right angle
So we have a right-angled triangle with the length from the external point to the center of the circle as hypotenuse;
While the radius and the length of the tangent to the circle as the other sides
Using Pythagoras’ theorem, the square of the hypotenuse equals the sum of the squares of the two other sides
Let the length we want to calculate be x
x^2 = 3^2 + 4^2
x^2 = 9 + 16
x^2 = 25
x = √25
x = 5 cm

During an online sale, you buy three sweatshirts and two pairs of sweatpants for $85.50. Later you buy three more sweatshirts and four more pairs of sweatpants for $123. (You can never have too many sweats during a pandemic). What is the sale price of each sweatshirt and each pair of sweatpants?
Answer:
Step-by-step explanation:
let
x = price of a sweatshirt
y = trice of sweatpants
three sweatshirts and two pairs of sweatpants for $85.50
3x + 2y = 85.50
three more sweatshirts and four more pairs of sweatpants for $123
3x + 4y = 123
by solving the system of equations
3x + 2y = 85.50
3x + 4y = 123
we find
x = $16
y = $18.75
