So percent means parts out of 100

x%=x/100

so we jsut have to find

(red)/(total)

add 23+52+34+61+30=200

red=52

52/200

make bottom number 100

26/100=26%

answer is 26%

x%=x/100

so we jsut have to find

(red)/(total)

add 23+52+34+61+30=200

red=52

52/200

make bottom number 100

26/100=26%

Question

Which of the following is an undefined term?
Angle
Circle
Plane
Ray

Solution 1

**Answer:**

Plane is an undefined plane

**Step-by-step explanation:**

Hi, there are three undefined terms in geometry: point, line, and plane.

Point: has no size, only location . It can be named with a capital letter.

Plane: a flat surface that has no thickness, that extends infinitely n every direction. Â Is named Â by a single letter or by three coplanar, but non-collinear, points.

Line: Set of points extending in either direction infinitely.

Angle, circle, and ray are not undefined terms. Â are not Plane.

Solution 2

I think it would be C.plane... I had this question a while ago and I think its right... plz tell me if I am wrong. Thanks.

Question

A triangle has an area of 36 square feet. If the height of the triangle is 6 more feet than its base, what is its height and base?

Solution 1

If b is the base then the height h=b+6. As we have S=bh/2 then

36=b(b+6)/2;

bÂ˛+6b-72=0;

D/4=3Â˛+72=81

bâ=-3-9=-12

bâ=-3+9=6.

The base is always positive so b=6, h=6+6=12.

Answer: base=6 ft, height=12 ft.

36=b(b+6)/2;

bÂ˛+6b-72=0;

D/4=3Â˛+72=81

bâ=-3-9=-12

bâ=-3+9=6.

The base is always positive so b=6, h=6+6=12.

Answer: base=6 ft, height=12 ft.

Question

Factor completely 2x^3+6x^2+2x+6

Solution 1

2x^3+6x^2+2x+6

= 2(x^3 + 3x^2 + x +Â 3)

= 2[x^2 (x + 3) + (x + 3)]

= 2(x^2 + 1)(x + 3)

hope it helps

= 2(x^3 + 3x^2 + x +Â 3)

= 2[x^2 (x + 3) + (x + 3)]

= 2(x^2 + 1)(x + 3)

hope it helps

Solution 2

F(-3) = 2*-27 + 6*9 + 2*-3 + 6 =Â 0

so x + 3 is a factor

dividing the function by x + 3Â gives the quotientÂ

2x^2 + 2Â Â = 2 (x^2 + 1)

So the factors are 2(x^2 + 1)(x + 3)Â Answer

so x + 3 is a factor

dividing the function by x + 3Â gives the quotientÂ

2x^2 + 2Â Â = 2 (x^2 + 1)

So the factors are 2(x^2 + 1)(x + 3)Â Answer

Question

A gumball machine contains 23 green gumballs, 52 red gumballs, 34343434 blue gumballs, 61 yellow gumballs, and 30 pink gumballs. What percentage of the gumballs are red?

Solution 1

So percent means parts out of 100

x%=x/100

so we jsut have to find

(red)/(total)

add 23+52+34343434+61+30=34343600

red=52

52/34343600

divide out

0.0000015141103/1

multiply by 100/100

0.00015141103/100=0.00015%

make bottom number 100

26/100=26%

answer is 26%

x%=x/100

so we jsut have to find

(red)/(total)

add 23+52+34343434+61+30=34343600

red=52

52/34343600

divide out

0.0000015141103/1

multiply by 100/100

0.00015141103/100=0.00015%

make bottom number 100

26/100=26%

answer is 26%

Question

. Convert 5Ď/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 5Ď / 3 radiansÂ = 180 /Â ĎÂ Â * 5Â Ď / 3 = 900 / 3 = 300 degrees Answer

soÂ 5Ď / 3 radiansÂ = 180 /Â ĎÂ Â * 5Â Ď / 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 â(52) in 2 seconds, so is simplyÂ â(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

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

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!
