Michelle can fold 4/54 baskets per minute = 8/108 baskets per minute.
Ruby can fold 4/108 baskets per minute.

Each minute Michelle and Ruby work together, they can fold
   8/108 +4/108 = 12/108 = 1/9
of a basket of clothes. For 8 baskets of clothes, it will take them
   (8 baskets)/(1/9 baskets/minute) = 72 minutes

A new aircraft control system is being designed that must be 98.0​% reliable. This system consists of two components in series.
sweet [91]

Answer:

98.99%

Step-by-step explanation:

The combined reliability of both components must be 98%. Given that both components must be functional and have the same reliability 'r', the minimum value of 'r' that meets the system requirements is given by:

0.98 = r^2\\r=0.9899=98.99\%

The level of reliability required for each component is 98.99%.

A frog leaps 24 inches. The highest point in the jump is 6 inches. Assume the frog starts at (0,0). What quadratic function mode
Ivanshal [37]
The path is in the shape of a parabola, the horizontal length is 24, so the middle point is at x=12, the symmetry line is x=12, the highest point (the vertex) is at (12,6)
the equation in vertex form is y=a(x-12)²+6
next, find a by using either one of the two points, the starting point (0,0) or the end point (0,24). obviously (0,0) is easier to calculate:
0=a(0-12)² +6
a=-1/24
so the quadratic equation is y=-\frac{1}{24} (x-12)^2+6

Question #3: Complete the statement below to show the correct value of 100%. Part A: The expression 100 3 = 10 because 100 = 102
BigorU [14]

Answer:

Step-by-step explanation:

Part A.

Expression (100)^{\frac{1}{2}} = 10

Because 100 = (10)^{2} and [(10)^2]^{\frac{1}{2}}=10^1=10

[Since, (a^{2})^{\frac{1}{2}}=a^{2\times \frac{1}{2}}=a^1]

Part B.

When simplified, the answer is RATIONAL.

[Since, 10 can be written as \frac{10}{1}]
