I have no idea what I'm supposed to do here

The answer is A.
All of the angles in a triangle add up to 180 degrees. For an angle to be obtuse, it has to be over 90 degrees. Therefore , when added together angle Z and Y must equal less than 90 degrees (since 180-90=90). Then you know that angle Z and Y are congruent (meaning their measures are the same), so each angle must be less than 45 degrees (since if one was say, 50, then the other has to be the same, making the two add up to 100 and the other angle being 80, so it wouldn’t be obtuse anymore). Hope that helps :)

128.34 as a mixed number in simplest form
katrin2010 [14]
128.34
= 128+ 0.34
= 128+ 34/100
= 128+ (34/2) / (100/2)
= 128+ 17/50
= 128 17/50

128.34 written as a mixed number is 128 17/50~

A scientist runs an experiment involving a culture of bacteria. She notices that the mass of the bacteria in the culture increas
Genrish500 [490]

The growth factor for the mass of bacteria is 2.8 in 1 week.

Step-by-step explanation:

Step 1:

It is given that the bacteria in the culture increase by 260% per week. Now we assign values to get a better understanding. If there were 1,000 bacteria in the culture at the start of the week there would be 1,000 + 260% at the week's end = 1,000 + 2,600 = 3,600 at the week's end.

Step 2:

To calculate the growth factor, we calculate the difference between the present value and the past value and divide it by the past value.

Here the past value is 1,000 and the present value is 2,600.

Growth factor = \frac{difference in values}{past value} = \frac{3,600-1,000}{1000} = \frac{2,600}{1,000} = 2.6.

So the growth factor is 2.6 per week.

A tortoise walks 3 inches in 1 second. How many feet per second can the tortoise walk?
den301095 [7]
Set up the conversion factor like this:

\frac{3in}{1} * \frac{1ft}{12in}

The inches are in the denominator while the feet are in the numerator in the conversion factor.  It's set up this way because the numerators and denominators have to be able to cancel out.  In this case, the inches would cancel out, and you would end up with 3/12 feet, which is also 0.25 feet.  The turtle walks 0.25 feet per second.
