Question

. Convert 5Ï€/3 to degrees

Solution 1

radians is equal to 180 degrees.

Convert to 180 to get the following fraction:

Multiply 5 and 180 together to get the following fraction:

Simplify the fraction.

= 300

The answer is**300 degrees.**

Convert to 180 to get the following fraction:

Multiply 5 and 180 together to get the following fraction:

Simplify the fraction.

= 300

The answer is

Solution 2

Î radiansÂ = 180 degrees

soÂ 5Ï€ / 3 radiansÂ = 180 /Â Ï€Â Â * 5Â Ï€ / 3 = 900 / 3 = 300 degrees Answer

soÂ 5Ï€ / 3 radiansÂ = 180 /Â Ï€Â Â * 5Â Ï€ / 3 = 900 / 3 = 300 degrees Answer

Question

2. The robot was initially placed at position (6,9), and at = 2 seconds, its position is (10,15). a. How far did the robot travel in 2 seconds?
b. What is the speed of the robot?
Could you work it out

Solution 1

what's its speed?Â well, it traveledÂ âˆš(52) in 2 seconds, so is simplyÂ âˆš(52)/2, which is about 3.6 units per second.

Question

Challenger Elementary School has 8 0 0 800800 students. Every Wednesday, 1 2 % 12%12, percent of the students stay after school for Chess Club. How many students attend Chess Club on Wednesdays?

Solution 1

You need to calculate 12% of 800.

To find a percent of a number, multiply the percent by the number.

Change the percent into a decimal by dividing the percent by 100 (move the decimal point of the percent two places to the left.)

12% of 800 =

= 12% * 800

= 0.12 * 800

= 96

Answer: 96 students

Question

_________________ lines are lines that never intersect and are not coplanar. A) Parallel B) Perpendicular C) Skew D) Transversal

Solution 1

The answer is c- skew lines

Solution 2

Hey There! I'll be glad too help you.

**Skew lines are lines that never intersect and are not coplanar.**

So the answer would be**C**. ^-^

So the answer would be

Question

If BC is tangent to circle O and OB is a radius, what kind of triangle is OBC?

Solution 1

Hi there!

Triangle OBC is aÂ**right triangle**. This is because where the radius and the tangent meet creates a right angle. A right angle is created due to the theorem that states that a radius is perpendicular to its tangent.

Hope this helps!! :)

If there's anything else that I can help you with, please let me know!

Triangle OBC is aÂ

Question

What is the range of the data set 2 | 1, 3, 8, 8
5 | 2, 4, 6, 6, 7
6 | 0, 1, 1
Key: 6| 0 means 60 please help i do not get this plz solve

Solution 1

The range is the difference between the highest and lowest values.

The highest value is 61.

The lowest value is 21.

range = highest value - lowest value = 61 - 21 = 40

The highest value is 61.

The lowest value is 21.

range = highest value - lowest value = 61 - 21 = 40

Question

The square root of 136 is between which two whole numbers?

Solution 1

The square root is between 11 and 12 but closer to 12.Â

Hope this helps!Â

Hope this helps!Â

Solution 2

The square root of 136 is between 11 and 12. Hope I helped!

Question

Use the remainder theorem to determine the remainder when
A. 107
B. 57
C. 43
D. 93

Solution 1

That would be 3(5)^2 + 5(5) - 7 =Â 75 + 25 - 7Â = 93 answer

Question

Calculate the equation 6^2/2(3)+4=x

Solution 1

(6^2)/2(3)+4=x

so do the exponent

6^2=36

36/2(3)+4

divide

36/2=18

18(3)+4

54+4

58

x=58

so do the exponent

6^2=36

36/2(3)+4

divide

36/2=18

18(3)+4

54+4

58

x=58

Question

The dot product of u with itself is 12. what is the magnitude of u?

Solution 1

**Answer: Â The magnitude of the vector u is âˆš12 units.**

**Step-by-step explanation: Â **Given that the dot product of a vector u with itself is 12.

We are to **find the magnitude of the vector u.**

Let <a, b> represents the vector u.

That is, **u = <a, b>**

**Then, according to the given information, we have**

**Thus, the magnitude of the vector u is âˆš12 units.**

Solution 2

Let's say u = <a,b>.

we know it's dot product is 12, thus

we know it's dot product is 12, thus
