Answer:
for which question???????????????
This is a multiplication equation. So to solve for y, we must divide.
6.3/0.9 = 7
y = 7
If quantity t varies inversely with a quantity r ,
Then mathematically t α 1/r,
Introducing a constant, t = k/r .
When t = 6 then r = 5,
therefore, 6 = k/5
k = 6×5
k = 30 (Constant of variation)
Which means the equation connecting t and r will be t = 30/r
To find the value of t when r = 15, we use the equation of this variation
such that, t = 30/15
t = 2
Answer:
m∠A = 144°, m∠B = 36°
Step-by-step explanation:
Supplementary angles are angles that add up to 180 degrees.
Substitute 4(m∠B) for m∠A.
4(m∠B) + m∠B = 180
5(m∠B) = 180
<u>m∠B = 36°</u>
Substitute 36 for m∠B.
4(36) = m∠A
<u>m∠A = 144°</u>
To determine the common ratio of the geometric sequence, divide the second term with the first term. 480 divided by 768 equals 5/8. Further, the ratio of the third and second terms may be used to check the consistency of the common ratio. The ratio is also 5/8. Thus, the common ratio is 5/8.
