Step-by-step explanation:
since it is the midsegment, all involved and related line segments follow the 1/2 factor.
so, the length of the midsegment is precisely in the middle between the lengths of the top and bottom lines.
in the first drawing
22 = x + (x - 10)
22 = x + x - 10
32 = x + x = 2x
x = 16
in the second drawing
x = 15 + (15 - 8) = 15 + 7 = 22

Answer:
Step-by-step explanation:
If you multiply top and bottom of 7/2 by 2 as in (7 *2) / (2 * 2) = 14 /4
If you multiply 7/2 top and bottom by 4, you get 28/8
So 14/4 and 28/8 are both the same as 7/2

Let x1 = 36, y1 = −6, and y2 = 8, and let y vary inversely as x. Find x2.
Answers
Answer:
-30
Step-by-step explanation:
Using 'y' is vary inversely to 'x', the value of x₂ = -27.
What is inverse?The word inverse in mathematics "a function or operation which reverses the order or operation of another function or operation".
According to the question,
x₁ = 36, y₁ = -6, y₂ = 8 and x₁ is inversely proportional to y₁ which mean
(x₁) (y₁) = k
(36)(-6) = -216.
Formula for inverse is x = k([tex]\frac{1}{y}[/tex]).
In order to find x₂, x₂ = -216(1/8)
x₂ = -27
Hence, the value of x₂ = -27.

For the 50 students in an art contest, there will be 1 prize for first-place, 1 prize for second-place, and 3 prizes for honorable mention. What is the probability of winning a prize?
Answers
Step-by-step explanation:
there are 50 students and 5 prizes (1 + 1 + 3).
so, already in natural language we would say "there is 1 prize for every 10 students".
formally, remember the rule of probability : desired outcomes over total possible outcomes.
this is here
5/50 = 1/10 = 0.1
your can see it also this way :
if there was only 1 prize, each student would have a chance of 1/50 of winning.
now there are 5 prizes, which gives everybody 5 times the chance of winning. which is then 5×1/50 = 5/50 = 0.1

What is the IQR for 79 85 98 125 140
Answers
Hi there!
We have the numbers:
79 85 98 125 140
From the data, we can see that '98' is the median value as it is exactly in the middle. We can then split the data into equal groups on both sides of the median.
79 85
125 140
Since there are only two numbers, we can find the median of EACH sub-group (Q1 and Q3 respectively) by taking the average.
Q1 = (79 + 85)/2 = 82
Q3 = (140 + 125)/2 = 132.5
The IQR is simply the difference between Q3 and Q1, so:
IQR = 132.5 - 82 = 50.5
solve for x: x^3 + x^2 + x = 3

C) − 29/2
D) − 29/8
Answers
Answer:
A) 29/8
Step-by-step explanation:
Identify the blocks. As you can see there are 5 x blocks on the left, and 9 -1 blocks on the left. On the right there are 3 -x blocks and 20 1 blocks. With this, form the equation.
5x - 9 = -3x + 20
Add 3x to both sides.
8x - 9 = 20
Add 9 to both sides.
8x = 29
Divide both sides by 28 to get:
x = 29/8.

Tickets to games of a local basketball team cost $12 for students and $16 for adults. For one game, $3700 was collected and 250 tickets were sold. How many of each kind of ticket were sold? Write and solve a system of equations.
Answers
Answer:
12x + 16y = 3700
x + y = 250
x = 75 students
y = 175 adults
Step-by-step explanation:
y = 250 - x
12x + 16(250-x) = 3700
12x + 4000 - 16x = 3700
-4x = -300
x = 75
y = 250 - 75
y = 175
Find the particular solution of the differential equation that satisfies the initial condition f'(x) 4x, f(0) = 5 f(x) =
Answers
Answer: [tex]f(x)=2x^2+5[/tex]
Step-by-step explanation:
First integrate f'(x) so we can find the funtion f(x):
[tex]4\int\limits {x} \, dx =4[\frac{1}{2} x^2]=2x^2+C=f(x)[/tex]
The initial conditions say that when x = 0, the function equals 5. Let's write that down:
[tex]f(0)=5=2(0^2)+C=C[/tex]
Therefore, the integration constant 'C' must equal 5. This means that our function is:
[tex]f(x)=2x^2+5[/tex]
You work with 3 other students on a project for science class. Your group
zarns 329 points, or 94%, of the total possible points. How many points are
possible for the project?
Answers
Answer:
350 points are possible
Step-by-step explanation:
You take 329 divided by 94% or .94 to get 350.
100% of 350 is 350
To double check, 94% of 350 is 329 & 6% of 350 is 21. 329 +21 = 350
