60%. You count how many total (15) and then how many got below a 90 (9) and then divide 9 by 15.
Answer:
x = 95
Therefore the solution is 95
Step-by-step explanation:
<u><em>What is the solution to log Subscript 5 Baseline (x + 30) = 3</em></u>
<u><em /></u>
log₅(x+30) = 3
From our law of logarithm
5³ = x + 30
(but 5³ = 5 ×5×5=125)
125 = x + 30
Subtract 30 from both-side of the equation to get the value of x
125 - 30 = x + 30 -30
95 = x
x = 95
Therefore the solution is 95
We can check the correctness of our answer
log₅(x+30)
=log₅(95+30)
=log₅125
=log₅5³ ( Note: log₅5=1)
=1×3
=3
Answer:
The last statement is the true.
Step-by-step explanation:
As shown in the figure.
A'B' is the image of AB by dilation of factor x and the center of dilation is C
So, x = ![\frac{CA'}{CA} = \frac{CA'}{CA'+A'A} =\frac{2}{2+4} =\frac{2}{6} =\frac{1}{3}](https://tex.z-dn.net/?f=%5Cfrac%7BCA%27%7D%7BCA%7D%20%3D%20%5Cfrac%7BCA%27%7D%7BCA%27%2BA%27A%7D%20%3D%5Cfrac%7B2%7D%7B2%2B4%7D%20%3D%5Cfrac%7B2%7D%7B6%7D%20%3D%5Cfrac%7B1%7D%7B3%7D)
So, according to the previous, the true statement is:
He is incorrect because the scale factor is One-third. CB is actually 2 + 4 = 6. CB is the pre-image, so the scale factor is StartFraction C prime B prime Over CB EndFraction = StartFraction 2 Over 6 EndFraction = one-third.
9 is real answer hope you’re doing great
Answer:
9 hrs and 10 mins
Step-by-step explanation:
We can convert this into a proportion. 50/45 = x/495. Cross-multiply to get 45x = 50*495. Divide both sides by 45 to get x = 50*11 = 550 minutes or 9 hrs and 10 mins
