Answer:
PQR reduction of ABC in the ratio 16/24=2/3
PR =x = AC*2/3 = 30*2/3=20
QR = y= BC*2/3 = 9*2/3=6
Step-by-step explanation:
Answer:
x=20cm
y=6cm
Step-by-step explanation:
We are told ΔABC and ΔPQr are similar. This means their corresponding sides are in ratios to one another.
That means the ratio of AB to PQ, is equal to the ratio of AC to PR, is equal to the ratio of BC to QR. Written mathematically, this is:
Find x/PR
Since we know the values of AB, PQ, and AC, we can use to find PR (x):
1.5=
1.5x=30
x=20
Find y/QR
Since we know the values of AB, PQ, and BC, we can use to find QR (y):
1.5=
1.5y=0
y=6
Equation of parallel line:
1)Parallel means they have to have the same slope. Since our equation is y=2/3x+1, a line parallel to that would be(using out points) -5=2/3(-4)+b.
To find the y-intercept, solve for "b".
b=-7/3
Our equation would then be y=2/3x-7/3
2)Perpendicular lines have opposite-reciprocal slopes. our previous equation was y=2/3x+1, so our new equation would be -5=-3/2(-4)+b. Now lets solve for b.
b=-11
So our perpendicular equation would be y=-3/2x-11
Hope that was helpful. :)

Answer: Cluster Sampling
Step-by-step explanation:
In cluster sampling, researcher divides the population into groups ,which are called clusters. Then random sample of clusters are chosen ,and researcher conduct study to collect data about the population.
Here each bus is considered a cluster ,because busses are selected at random ,this sampling would be an example of cluster type of sampling.

Answer:
C. 30,000
Step-by-step explanation:
We know that, the exponential function for decay is,
where,
y = the amount after time t,
a = initial amount,
r = rate of decay.
The half-life of a unstable isotope is 10,000 years, so
Now the function becomes,
Now, only 1/8 of the radioactive parent remains, so
