AS we are supposed to find

\text{Types of concurrent constructions needed to find the orthocenter of a triangle}

\text{As we know that the orthocentre is}\\\text{as the point of intersection of altitudes from the vertices}\\

\text{Hence the types of concurrent construction required will be }\\\text{Intersection of the lines drawn from the vertex of the triangle and }\\\text{perpendicular to its opposite sides.}

Hence the correct option is A.

\text{Intersection of the lines drawn from each vertex of the triangle }\\ \text{and perpendicular to its opposite side.}\\

Your dinner bill comes to $19.68. Estimate your total cost for dinner with a 5% tax and a 20% tip on the original bill. Justify
barxatty [35]
Estimate:
Bill = $20 approximately.
5% tax on $20 = 20/20=$1
20 % on ($20) = $4
Total cost = $20+1+4 = $25
Total bill = $25 approximately.

Exact calculations
bill = 19.68
tax 5% = 0.98
Tip 20% of original = 3.94
Total bill = 19.68+0.98+3.94 = 24.60

In 6 years, Mariya will be as old as Vikram is now. In 2 years, Vikram will be three times older than Mariya. Find their ages no
Damm [24]

Answer:

Mariya is 1 year old

Vikram is 7 years old

Step-by-step explanation:

Here, we want to know the present ages of Mariya and Vikram.

Let the present age of Mariya be M and the present age of Vikram be V

From the question, we are told that in 6 years time, Mariya will be as old as Vikram is now

Thus, mathematically;

M + 6 = V ••••••(i)

Furthermore , in 2 years time Vikram will be 3 time older than Mariya

Mathematically;

( V + 2) = 3( M + 2)

V + 2 = 3M + 6

V = 3M + 6-2

V = 3M + 4 •••••••(ii)

So let’s equate the V

3m + 4 = m + 6

3m -m = 6-4

2m = 2

m = 1

But V = m + 6

V = 1 + 6

V = 7

In a class, 60% of the students are girls. There are 18 girls in the class.
N76 [4]

Answer:

The answer is 30

Step-by-step explanation:

If you were to do 50% of 30, it would be 15 students that are girls. There's 18 students that are girls though, so the extra 10% would make 18 students in the class girls. The remaining 40% would be 12 boys. So basically you're taking 10% from one side and putting it in the other because 50% of 30 is 15 (well this is at least how I would do it, I don't know how others would do it though)

Help me solve this question
irga5000 [103]
The correct answer is 1.

So, circle the 0 after the equals sign because the equation does not equal 0.

Anything raised by the power of 0 is 1.

This is known as the zero exponent rule :)
