find x if b is the midpoint of the line AC.
AB=6x-6 and BC=72

Answer:

7 cm and 49 cm²

Step-by-step explanation:

(a)

A square has 4 equal sides , then

28 cm ÷ 4 = 7 cm

The length of each side of the square is 7 cm

(b)

The area (A) of a square is

A = s² ( s is the side length ) , then

A = 7² = 49 cm²

Answer:

Step-by-step explanation:

Perimeter of square will be equal to the length of the  string

Perimeter of square = 28 cm

4*side = 28

Divide both sides by 4

Side = 28/4

Side = 7 cm

b) Area of square = side * side

                             = 7 * 7

                             =49 cm²

Answer:

45%

Step-by-step explanation:

18/40

You multiply this by 10/10 to get

180/400

And then you divide by 4 to get

45/100

= 0.45

= 45%

Answer:

Your final grade will be 77%

Step-by-step explanation:

40% will be from your test average which is 95

30% will be from your homework average which is 60

30% will be from your quiz average which is 70

Calculating based on these weights:

(40×95+30×60+30×70) / (40+30+30) = 7700 / 100 = 77.00%

Answer:

2nd option

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - [tex]\frac{1}{2}[/tex] x - 2 ← is in slope- intercept form

with slope m = - [tex]\frac{1}{2}[/tex]

Parallel lines have equal slopes , then

y = - [tex]\frac{1}{2}[/tex] x + c ← is the partial equation

To find c substitute (2, 5) into the partial equation

5 = - 1 + c ⇒ c = 5 + 1 = 6

y = - [tex]\frac{1}{2}[/tex] x + 6 ← equation of line

Step-by-step explanation:

This question asks for us to substitute values of variables into the following equation: -2xy

We know two pieces of information:

All we have to do is substitute the values for variables.

-2xy

-2(-4)(1)

= 8(1)

Answer:

280/8 = 35 "sets"

35*3 = 105 Constance

35*5 = 175 vowels

Step-by-step explanation:

There are 105 consonants and 175 vowels in a paragraph.

Vowels (such as a, e, I o, and u) and consonants combine to form words (the rest of the alphabet). The letter "y" is a little odd since it can function as a vowel or a consonant depending on the context. Spelling will be made easier for you if you understand how vowels and consonants combine to form words and sounds.

a speaking sound made by people when their teeth, tongue, or lips obstruct the breath from leaving their mouths. grammar. Except for the English vowels a, e, I o, and u, a consonant is a letter that represents a sound made in this way.

Given:
The ratio of vowels to Constance to a paragraph is 3:5 there are 280 letters in the paragraph.

First to find the number of sets in the paragraph as

[tex]\frac{280}{3+5} = \frac{280}{8} = 35[/tex]

Therefore, there are 35 sets in the paragraph.

So, 35 x 3 = 105 are consonants and

      35 x 5 = 175 are vowels.

Step-by-step explanation:

Since all the sides in equilateral triangle are equal ,Angles are also equal

Let it be x

The Angle sum property of triangle is 180

x+x+x=180

3x=180

x= 180/3

=60°

Answer: C. 75

Concept:

Here, we need to know the idea of quadrilaterals in a circle.

The opposite angles of quadrilaterals in a circle (cyclic quadrilaterals) are supplementary, meaning they add up to 180°

If you are still confused, please refer to the attachment below for a graphical explanation.

Solve:

Given information

The opposite angle of b = 105°

Given expression

b + opposite angle of b = 180°

Substitute values into the expression

b + 105 = 180

Subtract 105 on both sides

b + 105 - 105 = 180 - 105

b = 75°

Step-by-step explanation:

68 + (5t - 8) = 180

5t + 60 = 180

5t = 120

t = 24

Answer:

24

Step-by-step explanation:

5t-8 and 68 are the angles of a straight line so their addition will be180°.

5t-8 + 68 = 180

5t + 60 = 180

5t = 180-60

5t = 120

t= 120/5

t= 24

Hi there!

We've given with the base area and height. We know the formula for base area

Base area = πr²

154 = 22/7 × r²

154 × 7/22 = r²

49 = r²

√49 = r

7 = r

Now

TSA = 2πr(h + r)

TSA = 2 × 22/7 × 7(7 + 20)

TSA = 44(27)

TSA = 1188 cm²

Answer:

175 miles

Step-by-step explanation:

Hillary has travelled

320 + 350 = 670 miles

in the first two weeks.

Therefore, Hillary starts with 670 miles and needs to add a certain number of miles "x" to get 845 in total.

670 + x = 845

And if we subtract 670 from both sides:

x = 845 - 670 = 175

175 miles
