Q57) if 1/4 of a packet cover 1/5 then using a packet is using 4* 1/4 of it. This means that 4*1/5 of the garden would be covered which = 4/5.

q58) the total is 24 and 9 of them are boys. Therefore it follows that 9/24 of them are boys and so thats the probability of choosing a boy at random.

Recall that two angles are complementary if the sum of their measures is 90°. find the measures of two complementary angles if

gizmo_the_mogwai [7]

Let one angle be x
Let another angle be 17x
17x+x = 90
18x = 90
x = 90/18 = 5
one angle = x = 5
another angle = 17x =17*5 = 85

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.
