The weight of a full steel bead tire is approximately 800 grams, while a lighter wheel weighs only 700 grams. What is the weight
Leona [12618]

To convert, divide each tire's weight by 453.592 grams per pound:

800 grams ÷ 453.592 = 1.76 pounds
700 grams ÷ 453.592 = 1.54 pounds

Carmen is using the quadratic equation (x + 15)(x) = 100 where x represents the width of a picture frame. Which statement about
Leona [12618]
By expressing the equation in its standard format, we have: ax^2 + bx + c = 0. First, we expand (x + 15)(x) = 100 to get x^2 + 15x - 100 = 0. Next, from (x + 20)(x - 5) = 0, we find the solutions to be x = -20 and x = 5. Hence, the accurate choice is option B. We discard x = -20 since it is not a valid solution.

tester [12383]

Answer:

13.8%

Step-by-step explanation:

With six employees and six checks, there are a total of 36 (6x6) possible distributions. To determine the probability that exactly five individuals receive the correct checks, there’s only one correct distribution for each of them out of the 36 possibilities, resulting in the calculation of 1/36 for the first and then 1/36 for the subsequent checks. Therefore, the final probability becomes 5/36 = 13.8%.

Which are the roots of the quadratic function f(b) = b2 – 75? Select two options. b = 5 StartRoot 3 EndRoot b = Negative 5 Start
zzz [12365]

Answer:

b = 5√3

b = -5√3

Step-by-step explanation:

We have

f(b)=b^{2}-75

Keep in mind, the root of a function corresponds to the value of x at which the function's output is zero.

In this case

The roots of the equation are the b values for which f(b) equals zero.

Thus

For f(b)=0

b^{2}-75=0

b^{2}=75

Take the square root of both sides

b=(+/-)\sqrt{75}

Now simplify

b=(+/-)5\sqrt{3}

b=5\sqrt{3}  and b=-5\sqrt{3}

So we find that

b = 5√3

b = -5√3
