Apply The Triangle Sum Theorem To Find The Sum Of The Angles In The Pentagon. A Pentagon Can Be Divided

Answers

Answer 1

Step-by-step explanation:

according to angle sum property of triangle

sum of all 3 angles of triangle is 180°

and here it is given that the Pentagon is divided in 3 triangles,

now,

3×180 = 540°

therefore, option C 540° is correct

hope this answer helps you dear! take care

Answer 2

Answer:

540

Step-by-step explanation:

Each triangle only has 180 degrees

We have 3 triangle, 180 + 180 + 180 = 540 degrees

Select the number line model that matches the expression | -6 - (-3)∣

Answers

-6 - (-3) remember ( a number in between ) this means positive number so that would mean that that equation would be 3
The absolute value means the value in side will be positive. - - or 2 negative signs give a positive number (cancel each other out). So it becomes -6 plus 3 which is -3. This would be the answer but absolute value signs mean that this value inside (-3) has to be positive.
The correct answer is a number line that shows 3.

Simplify the scale 5mm: 1 meter , writing your answer in ratio form. ​

Answers

Answer:

1 : 200

Step-by-step explanation:

To get an answer in ratio form, we must convert meters into millimeters or we can convert millimeters to meters. Then we can get our answer.

Step 1: Convert.

=> 5 millimeters : 1 meter

=> 5 millimeters : 1000 millimeters

Step 2: Simplify.

=> 5 millimeters : 1000 millimeters

=> 1 millimeter : 200 millimeters

Key Note: Answer in ratio form is always unitless.

=> 1 : 200

So therefore, 1 : 200 is our ratio. Hoped this helped.

so my math teacher made us do a review and I forgot how to do 8.90 x 15 bc when I do it's not in the multiple choices help​

Answers

Answer:

133.5

An easy way of doing this is to ignore the decimal so consider it as 89 instead because 0 is insignificant. So do 89x15 = 1335 we know that 8.90 has 1 decimal place because 0 is not significant so you just add 1 decimal place which becomes 133.5

The width of a rectangle is the length minus 4 units. The area of the rectangle is 12 units. What is the width, in units, of the rectangle?

Answers

Answer:

the width is 3

Step-by-step explanation:

you divide the 4 by 12

Answer:

2 units

Step-by-step explanation:

Area = Length × Width of a rectangle

If Length = L

Width = L-4

So 12 units = L×(L-4)

12 = L^2 -4L

L^2 -4L -12=0

Simplify this equation

L^2 + 2L -6L -12 = 0

L( L+2) - 6(L+2) = 0

(L+2) (L-6) = 0

L+2 =0 Or L-6=0

L=-2 Or L= +6

But L can't take a negative value

therefore L= 6

Now if we substitute and check,

L× (L-4) = 6×2=12 units

width = 6-4 =2 units

x =

What is the frequency of an observation?

The frequency of a variable value is the number of times it appears in a particular observational series or data.

A variable's frequency is always a positive integer.

Here the heights in the condition of 5 < h ≤  10 appear as 4.

Here the heights in the condition of 10 < h ≤ 15 appear as 6.

Here the heights in the condition of 15 < h ≤ 20 appear as 5.

The required frequency table as

Heights, h cm      Frequency

0 < h ≤ 5                     5

5 < h ≤  10                   4

10 < h ≤ 15                   6

15 < h ≤ 20                  5

9. The area of a rectangular fence is 300 square feet. If the width of the
fence is 15 feet, then find its length.

Answers

Answer:

20 feet

Step-by-step explanation:

The area formula is lw=A, where l is the length, w is the width, and A is the area. So, plug in the known variables. This creates the equation l15=300. Then, solve for l by dividing both sides by 15. Therefore, l=20. You can check your answer by plugging in all of the variables to create the equation 20*15=300. This is a true statement, thus 20 feet must be the correct length.

Use matrices to rotate the vector v=<-4 , 1> by 270°. Write the resulting vector in component form

Answers

Using rotation rules, it is found that the resulting vector is:

v = <1, 4>

When a vector in component form <x,y> is rotated by 270 degrees, the rule is:

<x, y> -> <y, -x>

That is, x and y are switched, and the signal of x changes.

In this problem, the vector is v <-4, 1>, hence:

<-4, 1> -> <1, -(-4)> -> <1,4>

Hence, <1,4> is the resulting vector.
