Answer:
Option D
Step-by-step explanation:
a/3 = 8/6
a × 6 = 8 × 3
6a = 24
a = 24/6
a = 4
Hence,
Option A is correct
A random number table is used to select numbers at random making use of the first digits that make sense according to the value in question to produce a probability or a mean. Choose the numbers by random and select the first digits. The numbers <span>0, 1, 2, 3, 4, 5, and 6 represent 1, while the numbers 7, 8, and 9 represent 0. Add all the 1's and 0's and divide by the total count of numbers.</span>
Wavelength times frequency equals speed, so wavelength=1080/7000=0.154 feet.
Answer:
The answer is 23.
Step-by-step explanation:
Our equation here is (2x + y) + 5.
If x=4, and y=10, let's plug that in into our variables, and simplify!
[2(4) + (10)] + 5
= [8+10] + 5
=[18] +5
=23
Ok so you got -30+2r=4(4r-4)
You distribute and get -30+2r=16r-16
Then you subtract 16r on both sides to get -30-14r=-16, then you add 30 on both sides and get -14r=14 then divide both sides by -14 to get r by itself, so the answer is r=-1
