Answer:
a.
cm or 7.21cm
b.
cm or 13.04cm
c. x=
cm or 11.66cm, y=
cm or 13.82cm
Step-by-step explanation:
a. You have to find the length of the other two sides of the triangle using the information already given. The first side is 6cm and the other is 12-9=4cm. Because it's a right-angled triangle you can use pythagoras

b. You can use pythagoras again because it's a right-angle triangle

c. In this question you have to find x and y. We need to find x first using pythagoras

Now that we've found x we can find y using pythagoras but instead of find c, we will find another side

Hope this helps :)
He worked an 8 hour day 3 days.
Let x be the number of 8 hour days he works. Then 10-x is the number of 6 hour days he works.
8x + 6(10-x) = 66
Using the distributive property,
8x + 6*10 - 6*x = 66
8x + 60 - 6x = 66
Combining like terms,
2x + 60 = 66
Subtract 60 from both sides:
2x + 60 - 60 = 66 - 60
2x = 6
Divide both sides by 2:
2x/2 = 6/2
x = 3
There were 3 days he worked 8 hours.

Answer:
Explanatio1- To make 18 bags of snack mix, Sherry needs 4.5 cups of almonds.
As the original recipe is for 6 bags, and here Sherry wants to triple that amount. You have to multiply 1.5 x 3.
2- Sherry needs 6 cups of granola to make 12 bags of the snack mix.
If Sherry gets 6 bags using 3 cups of granola, she will get 12 by using 6 cups of granola.
3- If Sherry uses one cup of cranberries, she will need to use 2 cups of raisins.
As 1 cup of cranberries is the double of what the recipe states, Sherry should also double the amount of cups of raisins.
4- The recipe will make 2 bags of the snack mix if Sherry uses only one cup of granola.
As 1 cup of granola is a third of the amount detailed in the recipe for 6 bags, the amount of bags will also be reduced to a third. 6/3=2n:
