Can someone pls help me
Step-by-step explanation:
what is the problem here, what do you not understand ?
you do know fractions, and how to multiply and divide them ? because that would be a precondition for a teacher to give you such a problem to solve.
so, if you do know the handling of fractions, this is very basic and easy thing to solve.
let's get into it then :
2 similar triangles. that means all lengths of all lines in one triangle are the result of multiplying the corresponding lines in the other triangle by a constant factor.
that is the meaning of a scaling factor.
it is like on a map, where it says 1 unit on the map is that many units out there in reality.
your teacher was really nice to point out the right angles and even a second angle (37 degrees), so that we can immediately see, which side or line of one triangle corresponds to which side or line of the other.
when we imagine now to turn e.g. the smaller triangle so that it is oriented the same way as the larger one, we see that QS corresponds to LJ. and QR to LK. and RS to KJ.
so, we are going in the scaling process from left to right. that means we are starting with the larger triangle and turn it into the smaller triangle.
so, what (scaling) factor do I need to multiply with 15 to get 10 ?
it is the same factor to go also from 9 to 6 and from 12 to 8.
15×x = 10
x = 10/15 = 2/3
15 × 2/3 = 30/3 = 10
12 × 2/3 = 24/3 = 8
9 × 2/3 = 18/3 = 6
so, as you can see, 2/3 is the correct scaling factor.

A law firm offers a prepaid family plan that covers all of a family's legal services for as long as the family is enrolled
in the plan
. For this plan, a family pays a one-time enrollment fee of $10.00 plus $25.00 per month of enrollment in the
plan.
• For an additional monthly charge, any family member with a home-based business will also receive legal
services for that home business.
A family member who enrolled for both family and home-business legal services had a total cost of $484.00 for one
year. What was the additional monthly charge for legal services for the home business?
Answer:
The extra monthly charge for the family would be $14.50
Step-by-step explanation:
let x equal the additional monthly charge for legal services
[tex]10 + (25 + x)12 = 484 \\ 10 + 300 + 12x = 484 \\ 310 + 12x = 484 \\ 12x = 174 \\ x = 14.50[/tex]

solve for y 1/3x+2y=8
1. Simplify [tex]\frac{1}{3} x[/tex] to [tex]\frac{x}{3}[/tex]
[tex]\frac{x}{3} +2y=8[/tex]
2. Subtract [tex]\frac{x}{3}[/tex] from both sides
[tex]2y=8-\frac{x}{3}[/tex]
3. Divide both sides by 2
[tex]y=\frac{8-\frac{x}{3} }{2}[/tex]
4. Simplify [tex]\frac{8-\frac{x}{3} }{2}[/tex] to [tex]\frac{8}{2}[/tex] - x/3/2
y=8/2-x/3/2
5. Simplify 8/2 to 4
y=4-x/3/2
6. Simplify x/3/2 to x/3x2
y=4-x/3x2
7. Simplify 3x2 to 6
-y=4-x/6

Answer:
0
Step-by-step explanation:
If it takes 6 to 10 minutes to make something it's impossible to make it in less than 6 minutes. (the probability is 0)
mathamatically, you can use the CDF for a uniform distribution and get the same answer
(6-6)/(10-6)= 0

simplify 140/200 pleaseeeeee
Answer:
7/10
Step-by-step explanation:
140/200
the zero at the back of 140 will cancel the zero at the back of 200
2 divide 14=7
and 2 divide 20 =10
so;
140/200
=7/10
Nick jumps off a cliff. It takes him 2.2 s to hit the water below. What is the height of the cliff? g=9.8 m/s2
Answer:
9.8 x 2.2 = 21.56 m
distance = time x speed
speed = distance ÷ time
Step-by-step explanation:
The highest point he reached occurred at the vertex, which is at t = -b/2a = 2.2 second. Plugging in t = 2.2
9.8 x 2.2 = 21.56ft
Higher cliffs don't accelerate your fall -- acceleration is constant during free fall. The pull of gravity decreases infinitesimally at higher elevations, but it pulls you with an equal force from the first second of your jump until you decelerate when you hit the water.

Solve the system of equations by using substitution. Show all work for full credit. List your answer as an ordered pair. (4 points)
5x + 10y = 20
= 3y - 1
Answer:
[tex]x=2 , y=1[/tex]
Step-by-step explanation:
Since the second equation is fully simplified and we know what x equals, we plug the entire equation of x in for x in the top equation:
[tex]5(3y-1)+10y=20[/tex]
Now solve for y.
[tex]y=1[/tex]
Now plug y back into the bottom equation and solve for x.

In science class, Antonio and Anna were measuring the approximate speed of a marble as it
exits from an 8-foot-long ramp. They discovered that it took 2.1 seconds for the marble to

The marble was traveling at 4.05 miles per hour.
Since in science class, Antonio and Anna were measuring the approximate speed of a marble as it exits from an 8-foot-long ramp, and they discovered that it took 2.1 seconds for the marble to travel 12.5 feet from the end of the ramp, to determine approximately how fast was the marble traveling as it exited from the ramp to the nearest hundredth of a second, the following calculation must be performed:
12.5 / 2.1 = X 5.95 = X = feet per second 1 foot per second = 0.681818 miles per hour 5.95 x 0.681818 = X 4.05 = X
Therefore, the marble was traveling at 4.05 miles per hour.

Here's the solution :
1. The given figure is of a Rectangle, and we know that diagnonals of a Rectangle bisects each other.
so, PR = 2 × PT
that is :
PR = 2 × 10 = 20 unitsand both the diagnonals of a Rectangle are equal,
PR = QS = 20 units2. let's take the length of PQ = x and QR = y
Angle RPS = Angle PRQ = 60°
(because they form pair of Alternate Interior angles, which are equal)
By using trigonometry :
[tex] \sin(60) = \dfrac{x}{20} [/tex][tex] \dfrac{ \sqrt{3} }{2} = \dfrac{x}{20} [/tex][tex]x = \dfrac{20 \times \sqrt{3} }{ {2} } [/tex][tex]x = 10 \sqrt{3} \: \: units[/tex]similarly,
[tex] \cos(60) = \dfrac{y}{20} [/tex][tex] \dfrac{1}{2} = \dfrac{y}{20} [/tex][tex]y = \dfrac{20}{2} [/tex][tex]y = 10 \: \: units[/tex]And now, we know that area of triangle PQR is equal to :
[tex] \dfrac{1}{2} \times base \times height[/tex][tex] \dfrac{1}{2} \times x \times y[/tex][tex] \dfrac{1}{2} \times 10 \sqrt{3} \times 10[/tex][tex]50 \sqrt{3} \: \: unit {}^{2}[/tex]3. Area of Rectangle PQRS :
