GEOMETRY Identify the segment bisector of (FG) . Then find (FG)

Answers

Answer:

The segment bisector of FG is HI because it splits it into two equal parts. Since point F to the bisector equals 33 and the bisector to point G is the same, that would also be 33. 33+33=66=FG

Step-by-step explanation:

The measurement of the line segment FG is 66 units.

We need to identify the segment bisector of FG and then find FG.

What is the bisector of the line segment?

A segment bisector is a line, a ray, a line segment, or a point that cuts a line segment at the centre dividing the line into two equal parts. The word segment can also be referred to as line segment which means a segment is a part of the line that has fixed endpoints. The word bisect means cutting any object or line into two equal halves. Hence, a segment bisector is referred to as when two line segments bisect or cut each other at a point dividing the lines into equal halves.

From the given figure, HI is the bisector of the line segment FG.

Given that, 1/2 (FG)=33 units

⇒FG=66 units

Therefore, the measurement of the line segment FG is 66 units.

A straight angle is broken into 3 angles. The first angle measures 38°, the second angle is a right angle. What is the measurement of the 3rd angle?


Answer: The measurement of the 3\large ^{rd} angle is

Answers

Answer:

52°

Step-by-step explanation:

Let the measure of the third angle be x°.

Since, straight line is broken into three angles. So, the sum of all the three angles will be equal to 180°.

38° + 90° + x = 180°

128° + x = 180°

x = 180° - 128°

x = 52°

Answer:

52°

Step-by-step explanation:

So, we basically know that,

A straight Angle=180°

When it has been broken into 3 pieces, we have gotten one which is 38°and a right angle.

Now , we know that

A right angle= 90°

So, we need to do,

Sum of known angles= 38+90=128°

Lastly,

Unknown angle = 180° - 128° = 52°

Maya, Ahmad, and Joe served a total of 75 orders Monday at the school cafeteria. Joe served 2 times as many orders as Maya. Ahmad served 5 fewer orders
than Maya. How many orders did they each serve?

Answers

Total number of orders served by Maya, Ahmad and Joe on Moday = 75

Let the number of orders Maya served be x.

Then :

Number of orders Joe served = 2x

Number of orders Ahmad served = x - 5

This can be written in an equation as :

[tex] \tt \: 2x + x - 5 + x = 75[/tex]

[tex] = \tt 4x - 5 = 75[/tex]

[tex] = \tt 4x = 75 + 5[/tex]

[tex] = \tt 4x = 80[/tex]

[tex] = \tt \: x = \frac{80}{4} [/tex]

[tex] = \tt \: x = 20[/tex]

Which means :

Number of orders Joe served :

= 2 × 20

= 40

Thus, Joe served 40 orders.

Number of orders Maya served = 20

Number of orders Ahmad served :

= 20 - 5

= 15

Thus, Ahmad served 15 orders.

Therefore, Maya served 20 orders Ahmad served 15 ordersJoe served 40 orders.

Eli needs to place buoys at specific points in the inlet. He used the expression x4−81 to find the location for each buoy. Which expression is equivalent to Eli's expression?

Answers

Answer:

[tex]x^4 - 81 = (x - 3)(x+3)(x^2 + 9)[/tex]

Step-by-step explanation:

Given

[tex]x^4 - 81[/tex]

Required

Write an equivalent expression

Express 81 as 9^2

[tex]x^4 - 81 = x^4 - 9^2[/tex]

Express x^4 as (x^2)^2

[tex]x^4 - 81 = (x^2)^2 - 9^2[/tex]

Apply difference of two squares:

[tex]x^4 - 81 = (x^2 - 9)(x^2 + 9)[/tex]

Express 9 as 3^2

[tex]x^4 - 81 = (x^2 - 3^2)(x^2 + 9)[/tex]

Apply difference of two squares

[tex]x^4 - 81 = (x - 3)(x+3)(x^2 + 9)[/tex]

Hence, an equivalent expression is: [tex](x - 3)(x+3)(x^2 + 9)[/tex]

What is Regression line?

An estimate of the line that depicts the actual, but unidentified, linear relationship between the two variables is called a regression line. When the value of the explanatory variable is known, the regression line's equation is used to predict (or estimate) the value of the response variable.

Given:

Using the regression model

In II nd week the calories is 2950 and weight 250.

and, Vth week the calories is 7400 and weight 216.

let Exercise be x and the weight is y then

= (216 - 250)/ (7400- 2950)

= -9/ 4450

So, at the start of week john weight

y= -9/ 4500 x + 230

Now, At the end of 8 week John weighs

= -9/4500 (6100) + 230

= 217.7

Answers

Answer:

$2.70

Step-by-step explanation:

to find out he marks up each shirt by, just do 45% of 6 or 0.45 * 6 = $2.70

If Jerry buys a t-shirt for $6 and sells it for 45% more than she bought it, then jerry is selling them for $8.70 and making $2.70 for each t-shirt she sells, because 45% of 6 is 2.7

Part 1: G)52%  H)28%  I)19%   J)75%   K)95%

Part 2: 88%

Step-by-step explanation: I did math stuff lol, converted the decimal into a percent

Ex: 13/25= 0.52

0.52= 52%

Answer:

g. 52%

h. 28%

i. 19%

j. 75%

k. 95%

l. 88%

Step-by-step explanation:

g. 13/25

The denominator is currently 25. We must multiply it by 4 to reach 100. By converting the denominator to 100, the numerator will give us the answer to the percentage. However, when multiplying one side of the fraction (the denominator), we must also do the same to the other side of the fraction (the numerator).

Hence:

13 × 4 / 25 × 4

52/100

Since the denominator is 100, we can confidently say the answer is 52%

h. 7/25

Multiply by the numerator and the denominator by 4 so that the denominator equals 100.

7 × 4 / 25 × 4

28/100

28%

i. 19/100

The denominator for this fraction is 100, meaning the percentage is the numerator:

19%

j. 3/4

To get from 4 to 100, we must multiply by 25. What we do to the denominator, we must do to the numerator.

3 × 25 / 4 × 25

75/100

75%

k. 19/20

In order to change the denoninator to 100, multiply the denominator by 5 (20 × 5 = 100). Multiply by 5 to the numerator too to get the percentage.

19 × 5 / 20 × 5

95/100

95%

l. Out of 25 questions, Maria answered 22 correctly. If we write this as a fraction, we would put the total number (of questions) as the denominator with the correctly answered (number of questions) as the numerator:

22/25

We have to convert the denominator to read as 100 instead of 25. To do so, we must multiply 25 by 4. Whatever we do to the denominator, we must do to the numerator which means multiply the numerator by 4 as well.

22 × 4 / 25 × 4
