Answer:

D. Last gragh

Step-by-step explanation:

Answer:

the correct answers are:

a. ) Point H is the center of the circle that passes through points D, E, and F.

c. ) HE=HD

Point H, being the circumcenter, ensures it is the center of the circle through D, E, and F and that HE equals HD; other statements regarding unrelated points cannot be confirmed.

If Point H is the circumcenter of triangle DEF, then the following must be true:

The other statements regarding points L, M, N cannot be determined to be true without additional information, as they are not related to triangle DEF and its circumcenter directly.

In summary, Point H as the circumcenter ensures it is at the center of the circumscribable circle through D, E, and F, and that HE equals HD.

The length of the picture frame is 17 inches, which is found by substituting the given width and perimeter into the perimeter formula and solving for the length.

The question asks to calculate the length of a picture frame using the perimeter formula P = 2l + 2w, where P stands for the perimeter, l is the length, and w is the width. Given that the width (w) is 19 inches and the perimeter (P) is 72 inches, we can substitute these values into the formula:

P = 2l + 2w

72 = 2l + 2(19)

72 = 2l + 38

2l = 72 - 38

2l = 34

l = 34 / 2

l = 17 inches

So, the length (l) of the frame is 17 inches.

[tex]3+\frac{3}{4}x\geq 12[/tex]

Step-by-step explanation:

Given,

The number of hour he already practiced in this week = 3,

Also, she practices for three fourth of an hour each session,

If x be the number of remaining session,

So, the additional number of hours he practiced in this week = [tex]\frac{3x}{4}[/tex]

Thus, the total number of hours he practiced in this week = [tex]3+\frac{3x}{4}[/tex]

According to the question,

Total number of hours ≥ 12 hours

[tex]\implies 3+\frac{3x}{4}\geq 12[/tex]

Which is the required inequality.

Answer: The total cost of the dinner is found by adding the two prices together. Then this sum is multiplied by 1.05, which is 100% + 5%, to get a cost of $11.72.

Step-by-step explanation:

This is the sample answer.

To calculate the total cost including sales tax, convert the percent tax rate to a decimal, multiply it by the meal's cost, and add it to the original cost. In this case, a 5 percent tax on a $3.99 salad and a $7.17 fettuccini alfredo results in a final total cost of $11.72.

First, to find the sales tax for Abelita's Italian salad and Franco's fettuccini alfredo, you convert the tax rate from a percent to a decimal. The tax rate is 5 percent, which as a decimal is 0.05. Next, add the cost of the Italian salad ($3.99) and fettuccini alfredo ($7.17) to get the total cost before tax, which is $11.16. Multiply this total by the tax rate to find the amount of sales tax: $11.16 × 0.05 = $0.558. Round this to the nearest cent, which gives us $0.56.

The next step is to add the sales tax to the total cost before tax to find the final total cost. Thus, $11.16 (meal cost) + $0.56 (sales tax) = $11.72. Therefore, the total cost for their dinner, including the 5 percent sales tax, is $11.72.

The regular price of the table is $650.

The student has asked to find the regular price of a table that is currently on sale for $403, which is 38% less than the regular price. To find the regular price, we can consider the sale price to be 62% (100% - 38%) of the regular price. Let's denote the regular price as R. Thus, we can set up the equation 0.62 * R = $403. Solving for R, we divide both sides by 0.62 to find the regular price:

R = $403 / 0.62

R = $650

Therefore, to find the regular price of a table on sale for $403 at 38% off, we determine that the sale price is 62% of the regular price. By dividing the sale price by 0.62, we discover that the regular price is $650.

The value of kj is 15.

It is required to find the value of kj.

The midpoint is the middle point of a line segment. It is equidistant from both endpoints, and it is the centroid both of the segment and of the endpoints. It bisects the segment.

Given that:

k is the midpoint of hj and hk.

hk=x+6

hj=4x-6

We know that midpoint cuts the segment hj in 2 equal parts that means hk=kj and hk+kj=hj

hk+hk=hj

2hk=hj

2hk=hj

2 (x+6)=(4x-6)

2x+12=4x-6

12+6=4x-2x

18=2x

Divide 2 on both sides, we get

18/2=2x/2

9=x

hk=kj=x+6=(9)+6=15

kj=15

Therefore, the value of kj is 15.

"It is a finite set of equations for which we find the solution."

For given question,

We have been given a system of equations.

4x +2y = -2                     ................(i)

x - 3y = 24                      ................(ii)

From equation (ii),

x = 24 + 3y                .............(iii)

Substitute this value of x in equation (i)

⇒ 4(24 + 3y) +2y = -2

⇒ 96 + 12y + 2y = -2

⇒ 14y = -98

⇒ y = -7

Substitute this value of y in equation (iii)

⇒ x = 24 + 3(-7)

⇒ x = 24 - 21

⇒ x = 3

Answer:

2^(6-3) = 2^3 = 8

Step-by-step explanation:

To simplify radical 64/8

We will express 64 and 8 in powers of 2

64 = 2×2×2×2×2×2= 2^6

8 = 2×2×2=2^3

From the law of indices,

a^5 / a^3 = a^ (5-3) = a^2

Applying this law of indices to the given radical,

64/8 = 2^6/ 2^3

= 2^(6-3)

= 2^3 = 8

Also, we can try another way. since

64 = 2×2×2×2×2×2= 2^6

8 = 2×2×2=2^3

64/8 = 2×2×2×2×2×2 / 2×2×2

2×2×2 cancels out 2×2×2 and

It remains 2×2×2 = 8

So which ever way we do it,

radical 64/8 simplified is 2^3 = 8
