Given circle D, which of the following is an inscribed angle?

∠ EGD
∠ ADG
∠ AEG
∠ BCE

Answers

Answer:

<AEG

Step-by-step explanation:

Here, ∠AEG is an inscribed angle and the other three are not.

What is an inscribed angle?

"In geometry, an inscribed angle is the angle formed in the interior of a circle when two chords intersect on the circle. It can also be defined as the angle subtended at a point on the circle by two given points on the circle."

Here, ∠EGD is not an inscribed angle. Although it is interior of a circle, but there is no intersection of two chords on this circle.

∠ADG is not an inscribed angle, it is a central angle.

∠BCE is an not an inscribed angle. It is also interior of a circle, but there is no intersection of two chords on this circle.

Here, only ∠AEG is an inscribed angle as it is formed in the interior of a circle when two chords intersect on the circle.

Therefore, Option(C) is the correct answer.

Samantha, Nyla, and Jerry own shares of stock in the Triumph Hotels company. The shares of stock that they own have a combined value of $6,880. Samantha owns 70 shares, Nyla owns 50 shares, and Jerry owns 40 shares. What is the value of the shares Samantha owns?

Answers

Answer:

The value of the shares Samantha owns is $3,010

Step-by-step explanation:

Step 1

We add all the shares together and find out the cost of each share per dollar

Samantha owns 70 shares, Nyla owns 50 shares, and Jerry owns 40 shares.

Total amount of shares = (70 + 50 + 40) shares

= 160 shares

Step 2

The cost of share per dollar =

Values of shares/ Total number of shares

= $6,880/160 shares

= $43

1 share = $43

Step 3

The value of the shares Samantha owns is calculated as:

Number of shares Samantha owns × cost of share per dollar

Samantha owns 70 shares

Hence:

= 70 × $43

= $3010

The value of the shares Samantha owns is $3,010

Answer:

d = 200m

1400 m.

Step-by-step explanation:

This is direct variation.

At time 0 distance  run is zero.

d = km where d = distance, m = time and k is a constant.

k = the slope of the line joining the points and is  

800 / 4

= 200.

So the equation is d= 200m.

Answers

Answer:

x = 10

Step-by-step explanation:

The two triangles are similar, and it says that VUT is similar to EFG so side VT corresponds to side EG which means that 8 is just side VU divided by 2.

This means that side EG is 14 divided by 2 and that is 7.

This results in the equation " 2x - 13 = 7" First, add 13 to both sides of the equation to get rid of the -13. This gives 2x = 20. Then divide both sides by two to cancel out and get rid of the 2 in 2x. This leaves x as 10.

The length of the segment GI is 30.5 units

Step-by-step explanation:

In any triangle, the line segment joining the mid-points of two sides is parallel to the third side and equal to half its length

In ΔFHJ

∵ G is the mid-point of the side FH

∵ I is the mid-point of the side JH

∵ FJ is the 3rd side of the triangle

→ From the rule above

GI // FJ

GI = [tex]\frac{1}{2}[/tex] FJ

∵ FJ = 61 units

∴ GI = [tex]\frac{1}{2}[/tex] (61)

GI = 30.5

The length of the segment GI is 30.5 units

Robert and his children went into a bakery where they sell cupcakes for $4.75 each and cookies for $1.25 each. Robert has $50 to spend and must buy no less than 14 cupcakes and cookies altogether. If x represents the number of cupcakes purchased and y represents the number of cookies purchased, write and solve a system of inequalities graphically and determine one possible solution.

Answers

Answer:

Robert could buy 4 cupcakes and 20 cookies.

Step-by-step explanation:

Robert can buy 4 cupcakes and 20 cookies.

What is Inequality?

Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.

Given:

Price for cupcakes= 4.72

Price for cookies= 1.25

Robert has $50 to spend and must buy no less than 14 cupcakes and cookies altogether.

let x represents the number of cupcakes purchased and y represents the number of cookies purchased.

So, x + y ≥ 14

and, 4.75x + 1.25y ≤50

If we locate these inequalities on graph we get the intersection point (4, 20)

Hence, Robert can buy 4 cupcakes and 20 cookies.
