Answer: 36 / 2 1/4
Step-by-step explanation:
From the question, we are informed that Jared needs to drill holes 2 1/4 inches apart in a 36 inch section of his garage. The expression that he can use to figure out the number of holes he will need to drill will be:
= 36 ÷ 2 1/4
From the expression we can then calculate the number of hours to drill. This will be:
= 36 / 2 1/4
= 36 / 9/4
= 36 × 4/9
= 16
He'll need to drill 16 holes
Answer:
5(x+2)
Step-by-step explanation:
to factor it we need to find a common term(5) and then we take it out(divide) resulting in the answer abover
Let's calculate the areas of all three gardens
First garden
one garden that is 3 feet wide and 3 feet long
Area = length* width = 3 feet * 3 feet = 9 square feet
Second garden
3 feet wide and 6 feet long
Area = 3 feet * 6 feet = 18 square feet
Third garden
3 feet wide and 9 feet long
Area = 3 feet * 9 feet = 27 square feet
It means as we can see as the length increases by 2 times , the area also increases by 2 times every time.
Answer:
Step-by-step explanation:
hello,
I understand that there are only 4 cards and then the player draw a card out of the 4 cards, replace it so the second draw is still out of the 4 cards
<u>How many ways can you draw two cards?</u>
as the first card is replaced, this is 4*4=16
so there is 16 possibles ways
hearts hearts
hearts clubs
hearts diamonds
hearts spades
clubs hearts
clubs clubs
clubs diamonds
clubs spades
diamonds hearts
diamonds clubs
diamonds diamonds
diamonds spades
spades hearts
spades clubs
spades diamonds
spades spades
<u>out of these 16 ways, how many have same colour for both cards?</u>
I assume that there are only two colours Red and Black, so we can have
only 8 ways so the first probability is 8/16 = 1/2
<u>out of these 16 ways, how many are red ace first and black ace?</u>
There are 4 ways so the probability is 4/16 = 1/4
hope this helps
