1. Find the difference of arc measures.
mAC - mDE

Answers

Answer:

1.) Find the difference of arc measures.

mAC - mDE = 56

2.) Multiply the angle measure by 2.

2(mABC)= 56

3.) Moving points A and C to change

the angle and arcs and make a

conjecture.

The difference of arc measures

always equal 2 times the

angle measure.

The difference of arc measures is always equal to two times the angles measured at an external point of the circle.

What is an angle?

Angle is the space between the line or the surface that meets.  And the angle is measured in degree. For complete 1 rotation, the angle is 360 degrees.

The dimensions are given as

m∠ABC = 28°

mAC = 80

mDE = 24

The difference of arc measure will be

mAC - mDE = 80 - 24

mAC - mDE = 56

Multiply the measure of the angle m∠ABC by 2.

2 (m∠ABC) =  2 (28°)

2 (m∠ABC) =  56°

Moving points A and C to change the angle and arcs make a conjecture.

The difference of arc measures is always equal to two times the angles measured at an external point of the circle.

Hugh made a recipe that yields 8 and 1 over 2 cups. If each serving is 1 over 4 cup, which expression will help Hugh determine the number of servings his recipe will yield? 8 and 1 over 2 ⋅ 1 over 4 8 and 1 over 2 + 1 over 4 8 and 1 over 2 − 1 over 4 8 and 1 over 2 ÷ 1 over 4

Answers

A recipe yields = 8(1/2) cups.

And,

Each serving = (1/4) cups.

Therefore,

The number of servings his recipe will yield = (Total recipe yields) ÷ (Each serving) = 8(1/2) ÷ (1/4) = 8 and 1 over 2 ÷ 1 over 4 (Option D).

Step-by-step explanation:

t = 3 years

I = Prt

I = 18790 * 0.049 * 3

Step-by-step explanation:

The price of strawberries varies directly with the weight of the strawberries purchased. Two pounds of strawberries cost $6.

What is the cost of 7 pounds of strawberries?

Answers

Answer:

$21

Step-by-step explanation:

2Lbs. = $6

(2/2) = (6/2)

1Lbs. = $3

(1*7) = (3*7)

7Lbs = $21

Since strawberries are priced on weight, you first need to find the weight of one pound. The prices need to be proportional, so whatever you do to one side of the equal sign, you need to do to the other. Divide both numbers by 2. One pound costs three dollars. Then multiply both numbers by 7. Seven pounds of strawberries cost twenty-one dollars

There are 14 rows of seats in a cinema.
There are 15 seats in each row.
A film was shown in the cinema on Saturday,
Each ticket for the film cost £6.50
The tickets that were sold cost a total of £1274
How many tickets were not sold?​

Answers

Answer:

24 tickets were not sold

Step-by-step explanation:

Here, we want to get the number of unsold tickets

In each row, there are 15 seats

In the Cinema, there are 14 rows

The total number of seats is thus;

15 * 14 = 220 seats

If all the 220 seats were booked, the total amount of ticket sales would have been;

220 * 6.5 = £1430

But in this case, the amount generated is £1,274

Hence, the difference in these amounts will be;

1430 - 1274 = £156

To get the number of tickets unsold, we have to divide the amount here by the price per unit ticket

Mathematically, we have this as;

£156/£6.5 = 24

Which is a fourth degree trinomial with a leading coefficient of 3?
A) x2 – 3x4 + 13x
B) 3x4 – 8x3 = x + 2
C) 3x3 – x2 =12
D) x - x2 + 3x4​

Answers

Answer:

B.

Step-by-step explanation:

A fourth-degree trinomial with a leading coefficient of 3 is (B) [3x⁴-8x³=x+2].

What is a trinomial?A trinomial in elementary algebra is a polynomial made up of three terms, or monomials.An algebraic expression with three non-zero terms is called a trinomial. Trinomial expression examples: A trinomial with the variables x, y, and z is x + y + z.A trinomial in one variable, 2a² + 5a + 7, exists.

So, we know that a trinomial is made up of 3 terms.

4th-degree trinomial means that it has a power of 4.And with a coefficient of 3.

So, such expression is: 3x⁴ - 8x³ = x + 2

Therefore, a fourth-degree trinomial with a leading coefficient of 3 is (B) [3x⁴ - 8x³ = x + 2].

Lanya's house is located at (2 2/3, 7 1/3) on a map. The store where she works is located at (-1 1/3, 7 1/3). what is the distance from Lanya's home to the store?

Answers

Answer:

Option A: 4 units is the correct answer.

Step-by-step explanation:

Given that:

Layana's house is located at ([tex]2\frac{2}{3}, 7\frac{1}{3}[/tex])

Store is located at ([tex]-1\frac{1}{3},7\frac{1}3}[/tex])

We can find distance between two points by using distance formula.

S = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2[/tex]

The points can also be written as;

House (8/3, 22/3)

Store (-4/3, 22/3)

Putting values in the formula.

S = [tex]\sqrt{\frac{8}{3}-(-\frac{4}{3}))^2+(\frac{22}{3}-\frac{22}{3})^2[/tex]

S = [tex]\sqrt(\frac{8}{3}+\frac{4}{3}+0[/tex]

S = [tex]\sqrt{(\frac{8+4}{3})^2[/tex]

S = [tex]\sqrt{(\frac{12}{4})^2[/tex]

S = [tex]\sqrt{(4)^2[/tex]

S = 4 units

Hence,

Option A: 4 units is the correct answer.

1.)Students are using balloons to describe the expanding universe model. The students blow up several balloons and put them on the floor. Each balloon represents a different galaxy. How should the students move or change the balloons to demonstrate how the universe is expanding? All of the balloons should be moved to the center of the floor. Each balloon should be inflated more so that they are all increasing in size. Each balloon should be deflated so that there is more distance between the surface of each balloon. All of the balloons should be moved away from each other so there is more distance between them.2.)Evidence gathered by studying the composition and movement of distant galaxies indicates that the universe expanded rapidly from a single small point. The universe has continued to expand for over 13 billion years.Which statement is in agreement with the current understanding of the expanding universe?A.) All matter and energy were contained inside the small point.B.) Matter and energy came from areas of the universe and were attracted to the small point.C.) Matter and energy fell into the small point the same way a black hole attracts matter and energy.D.) Matter was considered into a single point until energy was attracted to the matter from dark areas of the universe.3.) Why do scientists believe the universe is still expanding?A.) The further away from an object is, the temperature and pressure eventually become, causing nuclear fusion.B.) Distant object shift in frequency toward red on the electromagnetic spectrum, which tells us objects are moving away from us.C.)

Jacob read the following information in an online science article: Tiny nerve endings in the ear are easily damaged. The risk of any permanent damage depends on the volume and the length of exposure.

Also, sitting as close as ten feet away from speakers at a concert can hurt your ears. Always allow twenty-four hours of rest for your ears after such an exposure to loud volume. What could Jacob claim in a research paper using the supporting evidence in the text? A. Nerve endings in the human ear are tiny and sensitive. B. Heavy and continued exposure to loud sounds can cause permanent hearing loss. C. Family history is important to hearing loss regardless of whether or not a person has had heavy exposure to loud sounds. D.
