The hypotenuse of one side of a right angled triangle are 5cm and 4cm respectively. what is the length of the other side

AURORKA [14]

Answer: 3cm

Explanation:

We can use Pythagorean’s theorem to find that other side:

a^2 + b^2 = c^2
a^2 + 4^2 = 5^2
a^2 = 25 - 16
a^2 = 9
a = 3

Therefore, the other side is 3cm

4. Represent the following sets in Roster form.

Phoenix [80]

The roster form of the given sets are:

(i) A = {1, 3, 5, 7, 9, 11, 13, 15, 17, 19}.

(ii) B = {1, 2, 3, 4, 5, 6, 7}.

(iii) C = {27, 64}.

(iv) D = {-1, 0, 1}.

The roster form of any set is the set with all elements of the set written in the set.

In the question, we are asked to represent the known sets in the roster form.

(i) A=The set of all odd natural numbers less than 20.

The set of all natural numbers, that is numbers after 1.

Odd numbers are numbers of the form 2n - 1.

Thus, the roster form is: A = {1, 3, 5, 7, 9, 11, 13, 15, 17, 19}.

Going similarly to the others, we will get:

(ii) B={y: y = n, n ∈ N, n ≤7}

Roster form is, B = {1, 2, 3, 4, 5, 6, 7}.

(iii) C = {x: x is a perfect cube, 8 < x < 125}

Roster form is, C = {27, 64}.

(iv) D= {x: x ∈ Z, -2 < x < 2}.

The roster form is, D = {-1, 0, 1}.

A printer takes 30 minutes to print a banner and a poster. I will take 50 minutes to print a banner and three posters. How long

qwelly [4]

Answer:

It takes the printer 20 minutes to print a banner

Step-by-step explanation:

Notice that there are two unknowns in this problem: the time to print a poster and the time to print a banner. Let's assign the letter "b" to the time it takes to print a banner, and "p' the time it takes to print a poster.

So we can write the following two equations involving the total amount of time that takes to print in the two cases:

$b+p=30\\b+3p=50$

We can solve for the unknown "p" by subtracting term by term in the equation set above:

$b+3p=50\\b+p=30\\\\b-b+3p-p=50-30\\2p=20\\p=10$

So it takes 10 minutes to print each poster, we can find the time it takes to print the banner by using the value we just found in one of the equations:

$b+p=30\\b+10=30\\b=20$

So, it takes 20 minutes to print a banner.
