what does 2.1 represent if you had to turn it into a fraction?

Answers

2.1 as a fraction is 21/10

1.) A, B and C are collinear points with coordinates -4, 2 and -7 respectively. Determine which point is between the other two.

2.) A, B and C are collinear points with AB = 5, BC = 9 and AC = 4. Which is between the other two?

3.) If the coordinates of A and B are -5 and 7 respectively and C is the midpoint of line AB, find the CA. What is the coordinate of C?

4.) In ∠ABC, ray BD is the angle bisector of ∠ABC. If the m∠ABD = 2x + 5 and m∠DBC = 5x - 10, find:
a. value of x
b. m∠ABD
c. m∠ABC

Answers

The point between the other two is point A

2. The point between the other two is point A3. The coordinate of C is 14. x = 5, ABD = 15 and ABC = 30

The point between the other two.

Arranging the given points in order, we get:

C (-7) < A (-4) < B (2)

We can conclude that, the point A is between points C and B.

The point between the other two.

Since A, B, and C are collinear, we have:

BA + AC = BC

Substituting the given values, we get:

5 + 4 = 9

9 = 9 --- true

We can conclude that, the point A is between points C and B.

Midpoint of AB

Given that

A = -5

B = 7

We have

Midpoint C = (7 - 5)/2

Midpoint C = 1

The value of x and the angles

Here, we have

Bisector BD

This means that

2x + 5 = 5x - 10

Evaluate

3x = 15

x = 5

So, we have

ABD = 2(5) + 5

ABD = 15

Then, we have

ABC = 2 * 15

ABC = 30

This means that the measure of angle ABC is 30 degrees

Caleb bought a jacket for $52 and 3 shirts for $12 each. The sales tax is 4.5%. How much did Caleb spend for all of the items, including tax?

Round to the nearest cent (hundredth). Include the $ symbol

Answers

Answer:

Caleb spent $91.96 for all of the items, including tax.

Step-by-step explanation:

First, let's calculate the cost of the shirts:

3 shirts * $12 per shirt = $36

Now, let's add the cost of the jacket and the shirts together:

$52 + $36 = $88

Next, let's calculate the amount of sales tax Caleb has to pay:

$88 * 4.5% = $3.96

Finally, let's add the sales tax to the total cost:

$88 + $3.96 = $91.96

Therefore, Caleb spent $91.96 for all of the items, including tax.

B.
$202.50
C.

Answers

The answer is A) $182.25

My work: 275/100 = 2.75 * .75 *.90 = 1.8225 and then multiply it by 100

It’s D. $170.50 Ez. 25%+10%=35%
So $270 35% of $270 = #170.50

The length of a rectangle is 5cm less than twice it's width. If the perimeter of the rectangle is no more than 80cm, what are the maximum possible dimensions?

Answers

Answer:

15 cm and 25 cm

Step-by-step explanation:

First let's mark the width with the letter b, and the length with a:

width: b

length: a = (2b - 5)

Then we have an inequality (P = 2a + 2b):

2 × (2b - 5) + 2b ≤ 80

4b - 10 + 2b ≤ 80

6b ≤ 80 + 10

6b ≤ 90 / : 6

b ≤ 15

a ≤ 2 × 15 - 5

a ≤ 25

The total number of questions in the biology test are 40.

What is percentage?

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

For one biology test, Jhon correctly answered 14 questions. This gave him a score of 35%.

Let the total number of questions be w.

Now, 35% of w=14

35/100 ×w=14

35w=1400

w=1400/35

w=40

Therefore, the total number of questions in the biology test are 40.

A telephone pole 60 feet high casts a shadow 80 feet long at the same time that a tree casts a shadow 120 feet. What is the height of the tree

Answers

The height of the tree would be 90 feet. To solve the problem, you would need to cross multiply so you would put 60( the height of the telephone pole) over x( the height of the tree) times 80 (the shadow of the telephone pole) over 120 ( the shadow of the tree). You multiply x and 80 and get 80x and multiply 120 and 60 and get 7,200. 80x=7,200, so the last step would be to divide 7,200 by 80 and you get 90. Make sure to add the units also in your answer (feet).

Since a telephone pole is 60 feet and it’s shadow is 80 you would say subtract 60 from 80 and it equals 20 . So that means you would do 120 - 20 and that equals 100
