A koala bear eats at a steady rate 15 leaves in 2 hours. In how many minutes does the koala eat 10 leaves?

ZanzabumX [31]

Answer:

80 minutes

Step-by-step explanation:

1 hour=60 minutes

2 hours=120 minutes

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

15/120=10/x

cross product

120*10=15*x

1200=15x

x=1200/15

x=80

We want to compare the quality of three Tablet products: Tablet Product A has a Mean Time Between Failures (MTBF) 10,000 hours,

skelet666 [1.2K]

Answer:

The Availability of tablets A,B and C are equal

Step-by-step explanation:

Computation for Which tablet has better Availability

Using this formula

Availability of Tablet=MTBF/ ( MTBF + MTTR)

Where,

MTBF represent Mean Time Between Failures

MTTR represent Mean Time To Repair

Let plug in the formula

Availability of Tablet A = 10,000hrs/(10,000hrs + 10hrs)

Availability of Tablet A= 0.999

Availability of tablet B = 11,000hrs/( 11,000hrs + 11hrs )

Availability of Tablet B= 0.999

Availability of Tablet C = 12,000hrs/ ( 12,000hrs + 12hrs)

Availability of Tablet C= 0.999

Based on the above calculation the Availability of all the 3 tablets are equal

Therefore the Availability of tablets A,B and C are equal.

Given the vectors A⃗ and B⃗ shown in the figure ((Figure 1) ), determine the magnitude of B⃗ −A⃗. A is 28 degrees above the posi

Vlad [161]

This problem is represented in the Figure below. So, we can find the components of each vector as follows:

$\bullet \ cos(28^{\circ})=\frac{Adjacent}{Hypotenuse}=\frac{A_{x}}{44} \\ \\ \therefore A_{x}=44cos(28^{\circ})=38.85m \\ \\ \\ \bullet \ sin(28^{\circ})=\frac{Opposite}{Hypotenuse}=\frac{A_{y}}{44} \\ \\ \therefore A_{y}=44sin(28^{\circ})=20.65m$

$\bullet \ cos(56^{\circ})=\frac{Adjacent}{Hypotenuse}=\frac{-B_{x}}{26.5} \\ \\ \therefore B_{x}=-26.5cos(56^{\circ})=-14.81m \\ \\ \\ \bullet \ sin(56^{\circ})=\frac{Opposite}{Hypotenuse}=\frac{B_{y}}{26.5} \\ \\ \therefore B_{y}=26.5sin(56^{\circ})=21.97m$

Therefore:

$\vec{A}=(38.85, 20.65)m \\ \\ \vec{B}=(-14.81, 21.97)m$

So:

$\vec{B}-\vec{A}=(-14.81, 21.97)-(38.85, 20.65)=(-53.66,1.32)$

Finally, the magnitude is:

$\boxed{\left| \vec{B}-\vec{A}\right|=\sqrt{(-53.66)^2+(1.32)^2}=53.67m}$

Can you please help me

1) -2.5, 0.11111...., 1/4, 5 4/5, sqrt51, sqrt 100

2) Using simplification,

-2.5 is smallest because its negative, and no other number is negative. 0.11111 is the second smallest

1/4 is 0.25, and the third smallest

5 4/5 is 5.8 and is the third biggest

sqrt of 51 is around 7.14, so its second largest

lastly, sqrt 100 is 10, making it the largest

3) 10-(-2.5)=12.5

If the value of 3/4 divided by x Is the whole number which number is the value of x?

gregori [183]

A whole number is a number that has no fractional representation.

Let's test all the options for the value of x.

When dividing a fraction by another fraction, the divisor will be in its reciprocal form.

1. 3/4 × 2/3

= 6/12 = 1/2

1/2 isn't a whole number.

2. 3/4 × 2/1

= 6/4 = 3/2

3/2 isn't a whole number.

3. 3/4 × 6/1

= 18/4 = 9/2

9/2 isn't a whole number.

4. 3/4 × 8/1

= 24/4 = 6

6 is a whole number.

Hence the answer is 1/8.

Hope it helps. :)
