Order these list of decimals from smallest to largest -8.91 4.56 -2.8 0.62
vodka [1.7K]

Answer: -8.91, -2.8, 0.62, 4.56

Step-by-step explanation:

The negative numbers are smaller than the positive ones. The larger number behind the negative sign is smaller. Therefore, -8.91 is smaller than -2.8 so -8.91 is first and -2.8 is second. The last two numbers are positive so you compare them. 0.62 is smaller than 4.56 so the list of decimals from smallest to largest is -8.91, -2.8, 0.62, 4.56.

Hope this helps!

When you flip a biased coin, the probability of getting a tail is 0.31. Find the probability of getting a head
Genrish500 [490]
Well if the probability of getting a tail is 0.31 then the probability of getting a head must be 0.69 because 0.31 is much like 31% and the last 0.69 makes 69% resulting in the total 100% chance when combining the outcome chances seeing as a coin only has 2 sides. (Assuming we are speaking of an U.S. coin here) <span />

The parallelogram has a base of 8 cm and corresponding height of 4 cm. The parallelogram is changed proportionally and is dilate
sukhopar [10]

Answer:

The area of the new reduced parallelogram after dilation is 8 cm^2

Step-by-step explanation:

Mathematically, the area of a parallelogram = b * h

before dilation, area of the parallelogram = 8 * 4 = 32 cm^2

After dilation by a factor of 1/2, the base of the parallelogram becomes 1/2 * 8 = 4cm while the height becomes 1/2 * 4 = 2cm

Thus, the area of the dilated parallelogram is 4 * 2 = 8 cm^2

The quantity p varies inversely as the square of (q + 2) <br>p=5 when q = 3 <br>Find p when q = 8​
MArishka [77]

Answer:

p = 1.25

Step-by-step explanation:

varies inversely

p (q + 2)² = k

-----------------------

Find k

p=5 when q = 3

5(3 + 2)² = k

5(25) = k

125 = k

----------------------

Find p when q = 8​

p(8 + 2)² = 125

p(100) = 125

divide both sides by 100

p = 1.25
