It would be false b/c when you solve 0=5
Answer:
as we know Sara need 8 tube in 3 experiment
she will use 2 tube in 1 experiment
now she have 6 tube in other experiments
so the question said to find how many tube were used in both experiment equally so 3,3 test tube were needed for each of the other two experiment
Step-by-step explanation:
total tube=8 (3 experiment)
used =2tube (1 experiment)
remaining=8-2=6
now ,
dividing 6 into 2 equal part
so,=6/2=3
so 3 tube were used in 2nd experiment and 3in 3rd experiment
Answer:y=1.25x
Step-by-step explanation:
(fog) (x) = (5x - 7) / (5x - 4)
The denominator cannot be zero so the domain is All real x except x = 4/5
The measure of the angle x to the nearest hundredth is 22.62 degrees.
<h3>How to find the measure of an angle in a right triangle?</h3>
A right triangle is a triangle that has one of its angles as 90 degrees.
Therefore, the sides or angles can be found using trigonometric ratios, depending on the parameters given.
Hence, using trigonometric ratios,
cos x° = adjacent / hypotenuse
Therefore,
hypotenuse = 13 units
adjacent side = 12 units
Thus,
cos x = 12 / 13
cos x = 0.92307692307
x = cos ⁻¹ 0.92307692307
x = cos¹ 0.92307692307
x = 22.619864948
x = 22.62 degrees
Therefore, the measure of the angle x to the nearest hundredth is 22.62 degrees.
