jack and josh shared some sweets in the ratio 4:7 josh got 18 more sweets than jack how many sweets were there in total

66 sweets

Step-by-step explanation:

Step one:

We are told that the ratio for sharing the sweet is 4:7

that is Jack takes 4 parts and Josh takes 7 paths

If Josh got 18 more

then Let the amount that Jack got be x

so that Josh got x+18

step two:

applying the part to part method, we can find the quantity each of them go

4/7= x/x+18

cross multiply

7x= 4x+72

collect like terms

7x-4x= 72

3x=72

divide both sides by 3

x= 72/3

x= 24

so  Jack got 24 sweets

and Josh got 24+18=42 sweets

in all the sweets = 66 sweets

step-by-step explanation:

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
